    Hedgehog interacting protein (HHIP) was implicated in chronic obstructive pulmonary disease (COPD) by genome-wide association studies (GWAS). However, it remains unclear how HHIP contributes to COPD pathogenesis. To identify genes regulated by HHIP, we performed gene expression microarray analysis in a human bronchial epithelial cell line (Beas-2B) stably infected with HHIP shRNAs. HHIP silencing led to differential expression of 296 genes; enrichment for variants nominally associated with COPD was found. Eighteen of the differentially expressed genes were validated by real-time PCR in Beas-2B cells. Seven of 11 validated genes tested in human COPD and control lung tissues demonstrated significant gene expression differences. Functional annotation indicated enrichment for extracellular matrix and cell growth genes. Network modeling demonstrated that the extracellular matrix and cell proliferation genes influenced by HHIP tended to be interconnected. Thus, we identified potential HHIP targets in human bronchial epithelial cells that may contribute to COPD pathogenesis. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Background & objectives: Chronic obstructive pulmonary disease (COPD is a complex chronic inflammatory disease of the respiratory system affecting primarily distal respiratory pathways and lung parenchyma. This study was aimed at investigating the association of COPD with IREB2, CHRNA5, CHRNA3, FAM13A and hedgehog interacting protein (HHIP genes in a Tatar population from Russia. Methods: Six single nucleotide polymorphisms (SNPs (rs13180, rs16969968, rs1051730, rs6495309, rs7671167, rs13118928 were genotyped by the real-time polymerase chain reaction in this study (511 COPD patients and 508 controls. Logistic regression was used to detect the association of SNPs and haplotypes of linked loci in different models. Linear regression analyses were performed to estimate the relationship between SNPs and lung function parameters and pack-years. Results: The rs13180 (IREB2, rs16969968 (CHRNA5 and rs1051730 (CHRNA3 were significantly associated with COPD in additive model [Padj =0.00001, odds ratio (OR=0.64; Padj =0.0001, OR=1.41 and Padj =0.0001, OR=1.47]. The C-G haplotype by rs13180 and rs1051730 was a protective factor for COPD in our population (Padj =0.0005, OR=0.61. These results were confirmed only in smokers. The rs16969968 and rs1051730 were associated with decrease of forced expiratory volume in 1 sec % predicted (Padj =0.005 and Padj =0.0019. Interpretation & conclusions: Our study showed the association of rs13180, rs16969968 and rs1051730 with COPD and lung function in Tatar population from Russia. Further studies need to be done in other ethnic populations.

    Full Text Available The objective of the present study is to formulate and characterize a nanoparticulate-based formulation of a macromolecule in a hydrophobic ion pairing (HIP complex form. So far, HIP complexation approach has been studied only for proteins with molecular weight of 10–20 kDa. Hence, we have selected bovine serum albumin (BSA having higher molecular weight (66.3 kDa as a model protein and dextran sulphate (DS as a complexing polymer to generate HIP complex. We have prepared and optimized the HIP complex formation process of BSA with DS. Ionic interactions between basic amino acids of BSA with sulphate groups of DS were confirmed by FTIR analysis. Further, nanoparticles were prepared and characterized with respect to size and surface morphology. We observed significant entrapment of BSA in nanoparticles prepared with minimal amounts of PLGA polymer. Finally, results of circular dichroism and intrinsic fluorescence assay have clearly indicated that HIP complexation and method of nanoparticle preparation did not alter the secondary and tertiary structures of BSA.

    Streptococcus pyogenes is a significant bacterial pathogen in the human population. The importance of virulence factors for the survival and colonization of S. pyogenes is well established, and many of these factors are exposed to the extracellular environment, enabling bacterial interactions with the host. In the present study, we quantitatively analyzed and compared S. pyogenes proteins in the growth medium of a strain that is virulent to mice with a non-virulent strain. Particularly, one of these proteins was present at significantly higher levels in stationary growth medium from the virulent strain. We determined the three-dimensional structure of the protein that showed a unique tetrameric organization composed of four helix-loop-helix motifs. Affinity pull-down mass spectrometry analysis in human plasma demonstrated that the protein interacts with histidine-rich glycoprotein (HRG), and the name sHIP (streptococcal histidine-rich glycoprotein-interacting protein) is therefore proposed. HRG has antibacterial activity, and when challenged by HRG, sHIP was found to rescue S. pyogenes bacteria. This and the finding that patients with invasive S. pyogenes infection respond with antibody production against sHIP suggest a role for the protein in S. pyogenes pathogenesis. PMID:24825900

  6. Silencing mediated by the Schizosaccharomyces pombe HIRA complex is dependent upon the Hpc2-like protein, Hip4.

    Directory of Open Access Journals (Sweden)

    Holly E Anderson

    Full Text Available BACKGROUND: HIRA (or Hir proteins are conserved histone chaperones that function in multi-subunit complexes to mediate replication-independent nucleosome assembly. We have previously demonstrated that the Schizosaccharomyces pombe HIRA proteins, Hip1 and Slm9, form a complex with a TPR repeat protein called Hip3. Here we have identified a new subunit of this complex. METHODOLOGY/PRINCIPAL FINDINGS: To identify proteins that interact with the HIRA complex, rapid affinity purifications of Slm9 were performed. Multiple components of the chaperonin containing TCP-1 complex (CCT and the 19S subunit of the proteasome reproducibly co-purified with Slm9, suggesting that HIRA interacts with these complexes. Slm9 was also found to interact with a previously uncharacterised protein (SPBC947.08c, that we called Hip4. Hip4 contains a HRD domain which is a characteristic of the budding yeast and human HIRA/Hir-binding proteins, Hpc2 and UBN1. Co-precipitation experiments revealed that Hip4 is stably associated with all of the other components of the HIRA complex and deletion of hip4(+ resulted in the characteristic phenotypes of cells lacking HIRA function, such as temperature sensitivity, an elongated cell morphology and hypersensitivity to the spindle poison, thiabendazole. Moreover, loss of Hip4 function alleviated the heterochromatic silencing of reporter genes located in the mating type locus and centromeres and was associated with increased levels of non-coding transcripts derived from centromeric repeat sequences. Hip4 was also found to be required for the distinct form of silencing that controls the expression of Tf2 LTR retrotransposons. CONCLUSIONS/SIGNIFICANCE: Overall, these results indicate that Hip4 is an integral component of the HIRA complex that is required for transcriptional silencing at multiple loci.

    Mice lacking HIP/RPL29, a component of the ribosomal machinery, display increased bone fragility. To understand the effect of sub-efficient protein synthetic rates on mineralized tissue quality, we performed dynamic and static histomorphometry and examined the mineral properties of both bones and teeth in HIP/RPL29 knock-out mice using Fourier transform infrared imaging (FTIRI). While loss of HIP/RPL29 consistently reduced total bone size, decreased mineral apposition rates were not significant, indicating that short stature is not primarily due to impaired osteoblast function. Interestingly, our microspectroscopic studies showed that a significant decrease in collagen crosslinking during maturation of HIP/RPL29-null bone precedes an overall enhancement in the relative extent of mineralization of both trabecular and cortical adult bones. This report provides strong genetic evidence that ribosomal insufficiency induces subtle organic matrix deficiencies which elevates calcification. Consistent with the HIP/RPL29-null bone phenotype, HIP/RPL29-deficient teeth also showed reduced geometric properties accompanied with relative increased mineral densities of both dentin and enamel. Increased mineralization associated with enhanced tissue fragility related to imperfection in organic phase microstructure evokes defects seen in matrix protein-related bone and tooth diseases. Thus, HIP/RPL29 mice constitute a new genetic model for studying the contribution of global protein synthesis in the establishment of organic and inorganic phases in mineral tissues. PMID:20362701

    Full Text Available Abstract Background With the introduction of increasingly powerful mass spectrometry (MS techniques for clinical research, several recent large-scale MS proteomics studies have sought to characterize the entire human plasma proteome with a general objective for identifying thousands of proteins leaked from tissues in the circulating blood. Understanding the basic constituents, diversity, and variability of the human plasma proteome is essential to the development of sensitive molecular diagnosis and treatment monitoring solutions for future biomedical applications. Biomedical researchers today, however, do not have an integrated online resource in which they can search for plasma proteins collected from different mass spectrometry platforms, experimental protocols, and search software for healthy individuals. The lack of such a resource for comparisons has made it difficult to interpret proteomics profile changes in patients' plasma and to design protein biomarker discovery experiments. Description To aid future protein biomarker studies of disease and health from human plasma, we developed an online database, HIP2 (Healthy Human Individual's Integrated Plasma Proteome. The current version contains 12,787 protein entries linked to 86,831 peptide entries identified using different MS platforms. Conclusion This web-based database will be useful to biomedical researchers involved in biomarker discovery research. This database has been developed to be the comprehensive collection of healthy human plasma proteins, and has protein data captured in a relational database schema built to contain mappings of supporting peptide evidence from several high-quality and high-throughput mass-spectrometry (MS experimental data sets. Users can search for plasma protein/peptide annotations, peptide/protein alignments, and experimental/sample conditions with options for filter-based retrieval to achieve greater analytical power for discovery and validation.

    Full Text Available Abstract Background HIP1 Protein Interactor (HIPPI is a pro-apoptotic protein that induces Caspase8 mediated apoptosis in cell. We have shown earlier that HIPPI could interact with a specific 9 bp sequence motif, defined as the HIPPI binding site (HBS, present in the upstream promoter of Caspase1 gene and regulate its expression. We also have shown that HIPPI, without any known nuclear localization signal, could be transported to the nucleus by HIP1, a NLS containing nucleo-cytoplasmic shuttling protein. Thus our present work aims at the investigation of the role of HIPPI as a global transcription regulator. Results We carried out genome wide search for the presence of HBS in the upstream sequences of genes. Our result suggests that HBS was predominantly located within 2 Kb upstream from transcription start site. Transcription factors like CREBP1, TBP, OCT1, EVI1 and P53 half site were significantly enriched in the 100 bp vicinity of HBS indicating that they might co-operate with HIPPI for transcription regulation. To illustrate the role of HIPPI on transcriptome, we performed gene expression profiling by microarray. Exogenous expression of HIPPI in HeLa cells resulted in up-regulation of 580 genes (p HIP1 was knocked down. HIPPI-P53 interaction was necessary for HIPPI mediated up-regulation of Caspase1 gene. Finally, we analyzed published microarray data obtained with post mortem brains of Huntington's disease (HD patients to investigate the possible involvement of HIPPI in HD pathogenesis. We observed that along with the transcription factors like CREB, P300, SREBP1, Sp1 etc. which are already known to be involved in HD, HIPPI binding site was also significantly over-represented in the upstream sequences of genes altered in HD. Conclusions Taken together, the results suggest that HIPPI could act as an important transcription regulator in cell regulating a vast array of genes, particularly transcription factors and at least, in part, play a

    Full Text Available The interaction between HIP family proteins (HIP1 and HIP12/1R and clathrin is fundamental to endocytosis. We used circular dichroism (CD to study the stability of an HIP1 subfragment (aa468-530 that is splayed open. CD thermal melts show HIP1 468-530 is only stable at low temperatures, but this HIP1 fragment contains a structural unit that does not melt out even at 83C∘. We then created HIP1 mutants to probe our hypothesis that a short hydrophobic path in the opened region is the binding site for clathrin light chain. We found that the binding of hub/LCb was sensitive to mutating two distantly separated basic residues (K474 and K494. The basic patches marked by K474 and K494 are conserved in HIP12/1R. The lack of conservation in sla2p (S. cerevisiae, HIP1 from D. melanogaster, and HIP1 homolog ZK370.3 from C. elegans implies the binding of HIP1 and HIP1 homologs to clathrin light chain may be different in these organisms.

    2013-11-01

    Full Text Available Huntington’s disease (HD, a neurodegenerative disorder caused by an expanded CAG repeat in the huntingtin gene, impairs information processing in the striatum, which, as part of the basal ganglia, modulates motor output. Growing evidence suggests that huntingtin interacting protein 14 (HIP14 contributes to HD neuropathology. Here, we recorded local field potentials (LFPs in the striatum as HIP14 knockout mice and wild-type controls freely navigated a plus-shaped maze. Upon entering the choice point of the maze, HIP14 knockouts tend to continue in a straight line, turning left or right significantly less often than wild-types, a sign of motor inflexibility that also occurs in HD mice. Striatal LFP activity anticipates this difference. In wild-types, the power spectral density pattern associated with entry into the choice point differs significantly from the pattern immediately before entry, especially at low frequencies (≤13 Hz, whereas HIP14 knockouts show no change in LFP activity as they enter the choice point. The lack of change in striatal activity may explain the turning deficit in the plus maze. Our results suggest that HIP14 plays a critical role in the aberrant behavioral modulation of striatal neuronal activity underlying motor inflexibility, including the motor signs of HD.

    Huntingtin-interacting protein 1 related (Hip1R) is a novel component of clathrin-coated pits and vesicles and is a mammalian homologue of Sla2p, an actin-binding protein important for both actin organization and endocytosis in yeast. Here, we demonstrate that Hip1R binds via its putative central coiled-coil domain to clathrin, and provide evidence that Hip1R and clathrin are associated in vivo at sites of endocytosis. First, real-time analysis of Hip1R-YFP and DsRed-clathrin light chain (LC) in live cells revealed that these proteins show almost identical temporal and spatial regulation at the cell cortex. Second, at the ultrastructure level, immunogold labeling of 'unroofed' cells showed that Hip1R localizes to clathrin-coated pits. Third, overexpression of Hip1R affected the subcellular distribution of clathrin LC. Consistent with a functional role for Hip1R in endocytosis, we also demonstrated that it promotes clathrin cage assembly in vitro. Finally, we showed that Hip1R is a rod-shaped apparent dimer with globular heads at either end, and that it can assemble clathrin-coated vesicles and F-actin into higher order structures. In total, Hip1R's properties suggest an early endocytic function at the interface between clathrin, F-actin, and lipids.

    Huntingtin interacting protein 1 related (Hip1r) is an F-actin- and clathrin-binding protein involved in vesicular trafficking that is crucial for parietal cell function and epithelial cell homeostasis in the stomach. Gastric parietal cells in Hip1r-deficient mice are lost by apoptotic cell death, which leads to a progressive epithelial cell derangement, including glandular hypertrophy, zymogenic cell loss and expansion of a metaplastic mucous cell lineage known as spasmolytic polypeptide-expressing metaplasia (SPEM). The epithelial cell changes are associated with infiltration of inflammatory cells. As inflammatory mediators, such as IFNγ, have been shown to contribute to the development of the gastric epithelial cell metaplasia after Helicobacter infection, we tested whether IFNγ played a role in the spontaneous progressive epithelial metaplasia observed in Hip1r-deficient mice. Hip1r-deficient mice were crossed with IFNγ-deficient mice and single- and double-mutant mice were analyzed at 3 and 12 months of age. Histopathology scoring showed that loss of IFNγ tempered the spontaneous development of metaplastic lesions in Hip1r-deficient mice. Loss of IFNγ was observed to abrogate the glandular hypertrophy evident in Hip1r mutant stomach, although increased epithelial cell proliferation and elevated gastrin levels were not affected by the presence or absence of this pro-inflammatory cytokine. An analysis of cell lineage markers in the double-mutant mice demonstrated that IFNγ specifically affected the development of metaplastic mucous cells in the neck region, whereas the parietal cell, surface mucous cell and zymogenic cell alterations remained similar to the histopathology in the Hip1r mutant. Morphometric analysis showed that IFNγ was required for the mucous cell hypertrophy and hyperplasia observed in Hip1r-deficient mice. Together, these findings demonstrate that IFNγ is critical for the development of the gastric epithelial cell metaplasia that

    Introduction Hypochlorhydria during Helicobacter pylori infection inhibits gastric Shh expression. We investigated whether acid-secretory mechanisms regulate Shh gene expression through Ca2+i-dependent protein kinase C (PKC) or cAMP-dependent protein kinase A (PKA)-activation. Method We blocked Hedgehog signaling by transgenically overexpressing a secreted form of the Hedgehog interacting protein-1 (sHip-1), a natural inhibitor of hedgehog ligands, which induced hypochlorhydria. Gadolinium, EGTA+BAPTA, PKC-overexpressing adenoviruses, and PKC-inhibitors were used to modulate Ca2+i-release, PKC-activity and Shh gene expression in primary gastric cell, organ, and AGS cell line cultures. PKA hyperactivity was induced in the H+/K+-β-cholera-toxin overexpressing mice (Ctox). Results Mice that expressed sHip-1 had lower levels of gastric acid (hypochlorhydria), reduced production of somatostatin, and increased gastrin gene expression. Hypochlorhydria in these mice repressed Shh gene expression, similar to the levels obtained with omeprazole treatment of wild-type mice. However, Shh expression was also repressed in the hyperchlorhydric Ctox model with elevated cAMP, suggesting that the regulation of Shh was not solely acid-dependent, but pertained to specific acid-stimulatory signaling pathways. Based on previous reports that Ca2+i-release also stimulates acid secretion in parietal cells, we showed that gadolinium-, thapsigargin- and carbachol-mediated release of Ca2+i induced Shh expression. Ca2+-chelation with BAPTA+EGTA reduced Shh expression. Overexpression of PKC-α, -β and -δ (but not PKC-ε) induced Shh gene expression. In addition, phorbol esters induced a Shh-regulated reporter gene. Conclusion Secretagogues that stimulate gastric acid secretion induce Shh gene expression through increased Ca2+i-release and PKC activation. Shh might be the ligand transducing changes in gastric acidity to the regulation of G-cell secretion of gastrin. PMID:20816837

    Hip fractures are associated with significant morbidity and mortality and a major health problem in the United States (). Eighty percent of hip fractures are experienced by 80-year-old women. Plain radiographs usually confirm the diagnosis, but if there is a high level of suspicion of an occult hip fracture, magnetic resonance imaging or bone scan is the next step to confirm the diagnosis. Areas of the hip bone have varied bone strength and blood supply, making the femoral neck one of the most vulnerable areas for fracture. A consultation to an orthopedic surgeon will determine surgical interventions.

    Hip dysplasia, an abnormal laxity of the hip joint, is seen in humans as well as dogs and is one of the most common skeletal disorders in dogs. Canine hip dysplasia is considered multifactorial and polygenic, and a variety of chromosomal regions have been associated with the disorder. We performed a genome-wide association study in Dutch Labrador Retrievers, comparing data of nearly 18,000 single nucleotide polymorphisms (SNPs) in 48 cases and 30 controls using two different statistical methods. An individual SNP analysis based on comparison of allele frequencies with a χ(2) statistic was used, as well as a simultaneous SNP analysis based on Bayesian variable selection. Significant association with canine hip dysplasia was observed on chromosome 8, as well as suggestive association on chromosomes 1, 5, 15, 20, 25 and 32. Next-generation DNA sequencing of the exons of genes of seven regions identified multiple associated alleles on chromosome 1, 5, 8, 20, 25 and 32 (phip dysplasia. These genes are involved in hypertrophic differentiation of chondrocytes and extracellular matrix integrity of basement membrane and cartilage. The functions of the genes are in agreement with the notion that disruptions in endochondral bone formation in combination with soft tissue defects are involved in the etiology of hip dysplasia.

    Full Text Available Hip dysplasia, an abnormal laxity of the hip joint, is seen in humans as well as dogs and is one of the most common skeletal disorders in dogs. Canine hip dysplasia is considered multifactorial and polygenic, and a variety of chromosomal regions have been associated with the disorder. We performed a genome-wide association study in Dutch Labrador Retrievers, comparing data of nearly 18,000 single nucleotide polymorphisms (SNPs in 48 cases and 30 controls using two different statistical methods. An individual SNP analysis based on comparison of allele frequencies with a χ(2 statistic was used, as well as a simultaneous SNP analysis based on Bayesian variable selection. Significant association with canine hip dysplasia was observed on chromosome 8, as well as suggestive association on chromosomes 1, 5, 15, 20, 25 and 32. Next-generation DNA sequencing of the exons of genes of seven regions identified multiple associated alleles on chromosome 1, 5, 8, 20, 25 and 32 (p<0.001. Candidate genes located in the associated regions on chromosomes 1, 8 and 25 included LAMA2, LRR1 and COL6A3, respectively. The associated region on CFA20 contained candidate genes GDF15, COMP and CILP2. In conclusion, our study identified candidate genes that might affect susceptibility to canine hip dysplasia. These genes are involved in hypertrophic differentiation of chondrocytes and extracellular matrix integrity of basement membrane and cartilage. The functions of the genes are in agreement with the notion that disruptions in endochondral bone formation in combination with soft tissue defects are involved in the etiology of hip dysplasia.

    In newborns, US has an established role in the detection and management of developmental dysplasia of the hip. Later in childhood, when the limping child is a major diagnostic dilemma, US is extremely helpful in the identification of the varied disease processes underlying this condition, as transient synovitis, septic arthritis, Perthes disease and slipped femoral capital epiphysis. In adolescent practicing sporting activities, US is an excellent means to identify apophyseal injures about the pelvic ring, especially when avulsions are undisplaced and difficult-to-see radiographically. Later on, in the adulthood, US is an effective modality to diagnose tendon and muscle injuries about the hip and pelvis, identify effusion or synovitis within the hip joint or its adjacent bursae and guide the treatment of these findings. The aim of this article is to provide a comprehensive review of the most common pathologic conditions about the hip, in which the contribution of US is relevant for the diagnostic work-up.

    The neglected femoral neck fracture is one where there has been a delay of more than 30 days to seek medical help from the time of the original injury. Salvage procedures, such as osteotomy and other treatment options such as vascularized and nonvascularized bone grafts have high failure rates and arthroplasty procedures are not ideal, given the patient's young age and higher levels of activity. We designed a hollow bone graft dynamic hip screw (Hb-DHS) (modified DHS, Hb-DHS) for use in neglected femoral neck fractures. This study evaluates the efficacy and safety of the modified dynamic hip screw (DHS) with autogenous bone and bone morphogenetic protein 2 (BMP-2) composite materials grafting for the treatment of the neglected femoral neck fractures. A prospective study was carried out in twenty patients of neglected femoral neck fractures treated with the modified DHS with autogenous bone and BMP-2 composite materials grafting between July 2007 and February 2010. There were 14 men and 6 women with a mean age of 29.6 years (range 19-42 years). The mean time from injury to surgery was 9.7 weeks (range 6-16 weeks). The operation time, intraoperative blood loss, fracture healing time, Harris scoring for hip function and complications were recorded to evaluate treatment effects. The mean operation time was 75.8 min (range 55-100 min) with mean intraoperative blood loss volume of 105 mL (range 70-220 mL). The mean time to union was 17 weeks (range 12-24 weeks). One patient did not achieve union, and two patients had avascular necrosis of the femoral head. This patient with nonunion underwent intertrochanteric osteotomy. In patients with avascular necrosis one required total hip arthroplasty, the other did not require intervention at the last followup. A total of 14 patients (70%) had excellent results, 2 (10%) had good, 1 (5%) had moderate and 3 (15%) had poor results.

    Hip resurfacing arthroplasty is claimed to allow higher activity levels and to give better quality of life than total hip arthroplasty. In this literature review, we assessed the therapeutic value of hip resurfacing arthroplasty as measured by functional outcome. An extensive literature search was performed using the PubMed, Embase, and Cochrane databases. 9 patient series, 1 case-control study, and 1 randomized controlled trial (RCT) were included. Clinically and statistically significant improvement in sporting activity and hip scores were found in 10 studies. Studies with low levels of evidence have shown improvement in various different hip scores and one RCT showed better outcomes with hip resurfacing arthroplasty. There is no high-level evidence to prove that there is improved clinical outcome using hip resurfacing arthroplasty. More randomized research needs to be done.

    In a series of 57 hemiplegic patients who subsequently fractured their hips, it was found that hip fracture occurred significantly more often on the hemiplegic side. Hip fracture was equally common in right- and left-sided hemiplegia, and often occurred within one year of the stroke. Two factors seem to be important in the genesis of hip fractures in hemiplegic patients: the tendency of stroke patients to fall to the affected side as a result of impaired locomotor function, and the development of disuse osteoporosis in the hemiplegic limb.

  5. Hip Arthropathy in Haemophilia

    Directory of Open Access Journals (Sweden)

    Christian Carulli

    2017-04-01

    Full Text Available Hip arthropathy in haemophilic patients is disabling for hip and other common target joints. Even if bleedings in the hip are not frequent, femoroacetabular alterations may affect the functional ability of patients at a very young age. A haematologic prophylaxis combined with an adequate lifestyle and regular and low-traumatic physical activity are the keys to preventing such arthropathy. In the early stages of arthropathy, anti-inflammatory drugs and physical therapy may be sufficient to limit its progression. In cases of recurrent symptoms, viscosupplementation with hyaluronic acid, and chemical synoviorthesis are useful options. In more advanced stages, hip arthroscopy may be treated by synovectomy or loose body removal. For late stages, total hip arthroplasty (THA is mandatory. Until a few decades ago, the clinical outcomes after hip arthroplasty were variable, due to the different management of patients and the use of old generation implants and couplings. In the last decade, the introduction of the multidisciplinary management and the use of modern cementless implants with high performing materials and less invasive surgical techniques have dramatically improved the functional results. Nowadays, as is the case for other target joints, the purpose of the management in haemophilia centers is the early detection of any hip alterations—by clinical and ultrasound (US evaluations of patients in childhood—to reveal any early articular damage and to provide adequate treatment in case of symptoms. The present paper represents an updated review of the several approaches to hip arthropathy in haemophilia.

  6. TREATMENT OF HIP DYSPLASIA

    Full Text Available In this thesis, our purpose is to show that using physiotherapy on patients with hip dysplasia from the very beginning, in the first months of life, helps treating them faster. Common literature proposes to use physiotherapy on patients with hip dysplasia either after their recovery or in the terminal phase of recovery, claiming that any earlier intervention will prolong the hip recovery. The effects of hip dysplasia reflect over the whole musculoskeletal system, while it hinders the knees (genu valgum, the ankles (ankle valgus, calcaneal valgus and the spine (scoliosis especially at the lumbar level. The most spectacular are at the hip level, that is why we made an analytical evaluation only for this joint. To show the importance of physiotherapy for children with hip dysplasia we started from the hypothesis: untimely treatment for children with hip dysplasia has improved results in functional recovery and in obtaining a better stability, without the necessity of orthopedics or surgical interventions. The research methods used in this study are: the observation method, the bibliographic study method, the experimental method, the graphics method and the statistical mathematical method to process the data and to represent the results graphically. In the end, the results obtained are significantly different from the initial evaluations and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient improves stability and biomechanical parameters for the hip.

    Loss of muscle strength is associated with falls, which, in turn, are the main cause of hip fractures in elderly people. The factors that most influence loss of strength in elderly people are a decrease in muscle mass, i.e. sarcopenia, and an increase in fat, i.e. obesity. A prospective randomized clinical trial among patients who have undergone an operation for a traumatic hip fracture and who are aged 65 or above will be implemented. We shall compare a control diet against a high-protein diet enriched with β-hydroxy-βmethylbutirate, calcium and vitamin D. The diet will be administered during 30 days of hospitalization in the orthopaedic geriatric rehabilitation unit. There will be 50 patients in each arm of the study. The main objective is to assess whether the experimental diet, together with rehabilitation, improves functional recovery, measured on the Barthel index. Secondary objectives are to assess changes in body composition and the prevalence of sarcopenia, obesity and mortality one year after the hip fracture. We shall also assess whether there is a relationship between specific inflammatory markers, sarcopenia and functional recovery. Ageing is accompanied by changes in body composition that increase the risk of falls and progressive functional loss. These factors are a public health problem because they are highly associated with disability in older people. The present study seeks to gain knowledge of those factors that are most often associated with the onset of disability and those that can be modified through diet.

    2016-01-01

    Epidemiological evidence points strongly to a hazard of hip osteoarthritis from heavy manual work. Harmful exposures may be reduced by elimination or redesign of processes and use of mechanical aids. Reducing obesity might help to protect workers whose need to perform heavy lifting cannot be eliminated. Particularly high relative risks have been reported in farmers, and hip osteoarthritis is a prescribed occupational disease in the UK for long-term employees in agriculture. Even where it is not attributable to employment, hip osteoarthritis impacts importantly on capacity to work. Factors that may influence work participation include the severity of disease, the physical demands of the job, age, and the size of the employer. Published research does not provide a strong guide to the timing of return to work following hip arthroplasty for osteoarthritis, and it is unclear whether patients should avoid heavy manual tasks in their future employment.

    The management of hip injuries in the athlete has evolved significantly in the past few years with the advancement of arthroscopic techniques. The application of minimally invasive surgical techniques has facilitated relatively rapid returns to sporting activity in recreational and elite athletes alike. Recent advancements in both hip arthroscopy and magnetic resonance imaging have elucidated several sources of intraarticular pathology that result in chronic and disabling hip symptoms. Many of these conditions were previously unrecognized and thus, left untreated. Current indications for hip arthroscopy include management of labral tears, osteoplasty for femoroacetabular impingement, thermal capsulorrhaphy and capsular plication for subtle rotational instability and capsular laxity, lateral impact injury and chondral lesions, osteochondritis dissecans, ligamentum teres injuries, internal and external snapping hip, removal of loose bodies, synovial biopsy, subtotal synovectomy, synovial chondromatosis, infection, and certain cases of mild to moderate osteoarthritis with associated mechanical symptoms. In addition, patients with long-standing, unresolved hip joint pain and positive physical findings may benefit from arthroscopic evaluation. Patients with reproducible symptoms and physical findings that reveal limited functioning, and who have failed an adequate trial of conservative treatment will have the greatest likelihood of success after surgical intervention. Strict attention to thorough diagnostic examination, detailed imaging, and adherence to safe and reproducible surgical techniques, as described in this review, are essential for the success of this procedure.

    Historically, athletic hip injuries have garnered little attention; however, these injuries account for approximately 6% of all sports injuries and their prevalence is increasing. At times, the diagnosis and management of hip injuries can be challenging and elusive for the team physician. Hip injuries are seen in high-level athletes who participate in cutting and pivoting sports that require rapid acceleration and deceleration. Described previously as the "sports hip triad," these injuries consist of adductor strains, osteitis pubis, athletic pubalgia, or core muscle injury, often with underlying range-of-motion limitations secondary to femoroacetabular impingement. These disorders can happen in isolation but frequently occur in combination. To add to the diagnostic challenge, numerous intra-articular disorders and extra-articular soft-tissue restraints about the hip can serve as pain generators, in addition to referred pain from the lumbar spine, bowel, bladder, and reproductive organs. Athletic hip conditions can be debilitating and often require a timely diagnosis to provide appropriate intervention.

  16. Sequence analyses reveal that a TPR–DP module, surrounded by recombinable flanking introns, could be at the origin of eukaryotic Hop and Hip TPR–DP domains and prokaryotic GerD proteins

    2008-01-01

    The co-chaperone Hop [heat shock protein (HSP) organising protein] is known to bind both Hsp70 and Hsp90. Hop comprises three repeats of a tetratricopeptide repeat (TPR) domain, each consisting of three TPR motifs. The first and last TPR domains are followed by a domain containing several dipeptide (DP) repeats called the DP domain. These analyses suggest that the hop genes result from successive recombination events of an ancestral TPR–DP module. From a hydrophobic cluster analysis of homologous Hop protein sequences derived from gene families, we can postulate that shifts in the open reading frames are at the origin of the present sequences. Moreover, these shifts can be related to the presence or absence of biological function. We propose to extend the family of Hop co-chaperons into the kingdom of bacteria, as several structurally related genes have been identified by hydrophobic cluster analysis. We also provide evidence of common structural characteristics between hop and hip genes, suggesting a shared precursor of ancestral TPR–DP domains.

    Full Text Available Canine hip dysplasia (CHD is a hereditary developmental anomaly, most frequent in large dog breeds. Clinical confirmation of the disorder is based on hip X-ray imaging. Twenty Tornjak dogs aged between 9-36 months, and weighted from 35-42 kg were examined for CHD. Scoring was performed according to six clearly defined radiographic parameters by Flueckiger method (5. Dysplastic changes of various severity were observed in 11 dogs, while in 9 dogs changes were absent. The study describes 4 CHD cases of varying degrees of severity. The results indicate the presence of CHD in Bosnian Tornjak. Determining the incidence of dysplasia in this autochthonous breed requires a more detailed study, which will enable determination of the prevalence of dysplasia and analysis of the relationship to other dog breeds.

    Total hip replacement is a salvage procedure that is done to alleviate discomfort secondary to osteoarthritis in the hip, which is most often a result of hip dysplasia. Commercially available total hip replacement implants for small animal patients are classified as cemented or cementless. The INNOPLANT Total Hip Replacement system includes modular, screw-in cementless components that were developed to improve implant stability by maintaining as much normal anatomic structure, and by extension biomechanics of the coxofemoral joint, as possible. As a newer system, there are few data and no long-term studies available in the veterinary literature. Copyright © 2017 Elsevier Inc. All rights reserved.

    Older people living in nursing care facilities or older adults living at home are at high risk of falling and a hip fracture may occur after a fall. Hip protectors have been advocated as a means to reduce the risk of hip fracture. Hip protectors are plastic shields (hard) or foam pads (soft), usually fitted in pockets in specially designed underwear.This is an update of a Cochrane review first published in 1999, and updated several times, most recently in 2010. To determine if the provision of external hip protectors (sometimes referred to as hip pads or hip protector pads) reduces the risk of fracturing the hip in older people. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (December 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 12), MEDLINE (1950 to week 3 November 2012), MEDLINE In-Process (18 December 2012), EMBASE (1988 to 2012 Week 50), CINAHL (1982 to December 2012), BioMed Central (January 2010), trial registers and reference lists of relevant articles. All randomised or quasi-randomised controlled trials comparing an intervention group provided with hip protectors with a control group not provided with hip protectors. Two review authors independently assessed risk of bias and extracted data. We sought additional information from trialists. Data were pooled using fixed-effect or random-effects models as appropriate. This review includes 19 studies, nine of which were cluster randomised. These included approximately 17,000 people (mean age range 78 to 86 years). Most studies were overall at low risk of bias for fracture outcomes. Trials tested hard or soft hip protectors enclosed in special underwear in 18 studies.Pooling of data from 14 studies (11,808 participants) conducted in nursing or residential care settings found moderate quality evidence for a small reduction in hip fracture risk (risk ratio (RR) 0.82, 95% confidence interval (CI) 0.67 to 1.00); the absolute

    Musculoskeletal loading is an important factor affecting the development of osteoarthritis, bone remodelling and primary fixation of total hip replacement (THR). In this study, we analyzed the relation between muscular force, gait kinematics and kinetics and hip loading in 20 patients before and six weeks after THR. Hip contact forces were calculated from gait analysis data using musculoskeletal modelling, inverse dynamics and static optimization. We found aberrant pelvis and hip kinematics and kinetics before and six weeks after surgery, confirming previous findings in literature. Furthermore, we found a decrease in the total contact force and its vertical component. These changes result in a decrease of the associated inclination angles of the total hip contact force in the sagittal and transverse planes, changing the orientation towards more vertical implant loading after THR. These changes in hip loading were related to observed gait kinematics and kinetics. Most importantly, excessive pelvic obliquity and associated hip adduction related to impaired implant loading. We concluded, therefore, that physical therapy in the early post-operative phase should primarily focus on stretching of anterior and medial structures and strengthening of hip flexors and abductors to achieve normalization of the hip and pelvis kinematics and consequently normalize hip loading.

    Full Text Available Abstract Background High-sensitivity C-reactive protein (hs-CRP is an easily measured inflammatory biomarker. This study compared the association of percent body fat mass (%FM, body mass index (BMI, waist circumference (WC, and waist-to-hip ratio (WHR with hs-CRP in a Taiwanese population. Methods A total of 1669 subjects aged 40-88 years were recruited in 2004 in a metropolitan city in Taiwan. The relationships between obesity indicators and a high level of hs-CRP were examined using multivariate logistic regression analysis. The upper quartile of the hs-CRP distributions was defined as the high category group. The areas under the curve (AUCs of the receiver operating characteristic curves were calculated for all obesity indicators to compare their relative ability to correctly classify subjects with a high level of hs-CRP. Results After multivariate adjustment, the odds ratio for %FM was the only significant indicator that was associated with a high level of hs-CRP in men (1.55, 95% CI: 1.07-2.25. All indicators were associated with a high level of hs-CRP in women. In men, the AUCs for %FM were significantly higher than those for BMI, WHR, and WC, when demographic and lifestyle behaviors were considered (p Conclusions Our study demonstrates that %FM is the only obesity indicator that is strongly associated with a high level of hs-CRP after adjusting for sociodemographic factors, lifestyle behaviors and components of metabolic syndrome in both genders in a Taiwanese population aged forty years and over. In men, %FM had the greatest ability to classify subjects with a high level of hs-CRP when only demographic and lifestyle behaviors were considered. Our study finding has important implications for the screening of obesity in community settings.

    Majewski osteodysplastic primordial dwarfism type II (MOPDII) is characterized by severe prenatal and postnatal growth failure with microcephaly, characteristic skeletal dysplasia, an increased risk for cerebrovascular disease, and insulin resistance. MOPDII is caused by mutations in the pericentrin (PCNT) gene and is inherited in an autosomal-recessive manner. This study aimed to determine the incidence of hip pathology in patients with molecularly confirmed MOPDII and to describe the functional outcomes of surgical treatment. Thirty-three enrolled patients had a clinical diagnosis of MOPDII. Biallelic PCNT mutations or absent pericentrin protein was confirmed in 25 of these patients. Twelve patients (7 female) had appropriate clinical and radiographic records at this institution and were included in this study. The data collected included age at presentation, age at surgery, sex, body weight and height, weight-bearing status at diagnosis, and the clinical examination. Four patients (31%) had coxa vara: 3 unilateral and 1 bilateral. Three unilateral patients had in situ pinning at a mean age 4 years. The patient with bilateral coxa vara had valgus osteotomy at the age of 5 years. Two children had bilateral hip dysplasia and subluxation with no surgery. One patient had bilateral developmental hip dislocations. The patient was treated by open reduction-spica cast and 2 years after surgery, coxa valga was noted. Another patient was diagnosed at an age of 12 years with bilateral avascular necrosis of the hips. Four patients did not have hip pathology. Hip pathology is common among children with MOPDII; coxa vara is the most frequent diagnosis. Routine clinical and radiographic hip evaluation is important. The capital femoral epiphysis appears to slip down along the shaft, giving the appearance of a proximal femoral epiphysiolysis. A hip diagnosed with slipped capital femoral epiphysis in early life may progress to severe coxa vara. Level IV.

    The trabecular-orientated bionic hip stem was designed to mimic the natural force transmission through the femur in total hip arthroplasty, resulting in supposedly longer prosthesis survivability. The aim of this study was to compare the second-generation bionic hip stem to a standard uncemented hip stem. A group of 18 patients (21 hips) who underwent total hip arthroplasty with a bionic stem (bionic group) was compared with a historic group of 12 patients (12 hips) treated with standard anatomic hip stem (control group). During the first year after the procedure, the densitometric measurements of the bone around the prosthesis were taken. Radiographic and clinical assessments were additionally performed preoperatively and at the three month, six month, one year and three year follow-ups in the bionic group. In the bionic group, one patient was revised for aseptic loosening and 16 patients (19 hips) were available to the final follow-up. A significant decrease of bone mineral density was found in Gruen zones 3, 4 and 5 in the bionic group, and in zone 7 in both groups. The bionic group had a significantly higher bone mineral density in Gruen zone 1 at the one year follow-up. At the final follow-up, all prostheses were radiologically stable in both groups. Provided that a good implant position is achieved, comparable short-term results can be obtained using a bionic stem. Still, a decrease of bone mineral density in Gruen zone 7 occurred in both groups. Further studies are required to determine survivability of the bionic stem.

    studies were characterized as relevant to diagnosis (16 studies), disease staging (15 studies), prognosis (11 studies), and prearthritic hip disease (three studies). Sixteen different biomarkers demonstrated associations relevant to the diagnosis of hip OA, 16 biomarkers demonstrated similar associations for disease staging, and six for prognosis. Six biomarkers seemed to be the most promising, demonstrating associations with hip OA in multiple studies, including: urinary level of type II collagen telopeptide (n = 5 studies), serum cartilage oligomeric protein (n = 4 studies), and serum C-reactive protein (n = 4 studies). Only three studies investigated the role of biomarkers in prearthritic hip disease, including two in FAI and one in unspecified etiology of pain. There were no studies about biomarkers in hip dysplasia. Molecular biomarkers are increasingly investigated for their use in evaluating the pathophysiology of hip OA, but less so for prearthritic hip disease. Several biomarkers have demonstrated significant associations with hip OA across multiple studies. Further validation of these biomarkers is needed to assess their clinical use and potential application to prearthritic hip disease.

    Traumatic lesions of the hip in athletes may be clinically challenging because of the overlap in clinical presentation due to differing pathologies and the presence of multiple injuries. Imaging of the hip in the athlete has undergone a recent resurgence of interest and understanding related to the increasing accessibility and use of hip arthroscopy, which expands the treatment options available for intra-articular pathology. MR imaging and MR arthrography have a unique role in diagnosis of these pathologies, guiding the surgeon, arthroscopist, and referring clinician in their management of bony and soft tissue injury.

    Traumatic hip dislocations are high-energy injuries that often result in considerable morbidity. Although appropriate management improves outcomes, associated hip pathology may complicate the recovery and lead to future disability and pain. Historically, open reduction has been the standard of care for treating hip dislocations that require surgical intervention. The use of hip arthroscopy to treat the sequelae and symptoms resulting from traumatic hip dislocations recently has increased, however. When used appropriately, hip arthroscopy is a safe, effective, and minimally invasive treatment option for intra-articular pathology secondary to traumatic hip dislocation.

    Full Text Available Pseudogout is the acutest form of arthritis in the elderly. Although clinical manifestations vary widely, polyarticular involvement is typical mimicking osteoarthritis or rheumatoid arthritis. Monoarticular involvement is relatively rare and is generally provoked by another medical condition. There are reported cases of hip involvement by pseudogout in monoarticular form. However, all of the cases were presented as septic arthritis. In this report, we present a case of monoarticular hip involvement mimicking soft tissue abscess. We confirmed the pseudogout diagnosis after ultrasonographic evaluation of the involved hip joint and pathological and biochemical analysis of synovial fluid analysis. Diagnosis is important to avoid unnecessary medical and surgical treatment in cases of the bizarre involvement of hip in pseudogout.

    This paper is a refinement of previous studies in that only suitably radiographed dogs were included in the data base. The rate of hip dysplasia varied widely by breed from five percent in siberian huskies to eighty-three percent in english bulldogs. There was a significant difference in the prevalence of dysplasia within at least two breeds; golden retrievers and old english sheepdogs. Physical size per se did not appear to be an important determinant of hip dysplasia.

  20. DYSPLASIA OF HIP DEVELOPMENT: UPDATE

    Guarniero, Roberto

    2015-01-01

    The term “developmental dysplasia of the hip” (DDH) includes a wide spectrum of abnormalities that affect the hip during its growth, ranging from dysplasia to joint dislocation and going through different degrees of coxofemoral subluxation. The incidence of DDH is variable, and depends on a number of factors, including geographical location. Approximately one in 1,000 newborn infants may present hip dislocation and around 10 in 1,000 present hip instability. Brazil has an incidence of five per 1,000 in terms of findings of a positive Ortolani sign, which is the early clinical sign for detecting the disorder. The risk factors for DDH include: female sex, white skin color, primiparity, young mother, breech presentation at birth, family history, oligohydramnios, newborns with greater weight and height, and deformities of the feet or spine. Hip examinations should be routine for newborns, and should be emphasized in maternity units. Among newborns and infants, the diagnosis of DDH is preeminently clinical and is made using the Ortolani and Barlow maneuvers. Conventional radiography is of limited value for confirming the diagnosis of DDH among newborns, and ultrasound of the hip is the ideal examination. The treatment of DDH is challenging, both for pediatric orthopedists and for general practitioners. The objectives of the treatment include diagnosis as early as possible, joint reduction and stabilization of the hip in a secure position. Classically, treatment options are divided according to different age groups, at the time of diagnosis. PMID:27022528

    The purpose of this study was to verify the influence of the hip flexion angle on isokinetic rotator torque and acceleration times of the hip medial and lateral rotator muscles. Twenty-one healthy women were included in this study. The hip rotator function was evaluated at 3 different hip flexion angles (10°, 40°, and 90°). The results showed that both eccentric and concentric hip lateral rotator torques were greater at 40° of hip flexion when compared with 90°. Moreover, both the eccentric and concentric hip medial rotator torques were greater at 90° of hip flexion than at 40° and 10°, and greater at 40° than at 10°. In addition, both the eccentric and concentric hip medial to lateral rotator torque ratios were greater at 90° of hip flexion than at 40° and 10°, and greater at 40° than at 10°. Finally, the acceleration times of the hip medial rotator muscles were smaller at 90° of hip flexion than at 10° and smaller at 40° than at 10°. The current results highlight the importance of evaluating the hip rotator muscles at different hip flexion angles to comprehensively assess their functions.

    2011-01-01

    Background The renewed popularity of resurfacing hip arthroplasty in the last 10 years has generated a remarkable quantity of scientific contributions based on mid- and short-term follow-up. More than one paper has reported a consistent early revision rate as a consequence of biological or biomechanical failure. Two major complications are commonly described with resurfacing implants: avascular necrosis and femoral-neck fracture. A close relationship between these two events has been suggested, but not firmly demonstrated, whereas cementing technique seems to be better understood as potential cause of failure. Methods We performed an in vitro study in which four different resurfacing implants were evaluated with a simulated femoral head, two types of cement, (low and high viscosity) and two cementing techniques: direct (cement apposition directly on the femoral head) and indirect (cement poured into the femoral component). Results High-viscosity cement showed homogeneous distribution over the entire femoral head. Low-viscosity cement showed a massive polar concentration with insufficient, if not absent, distribution in the equatorial zone. Conclusion Polar cement concentration could be a risk factor for early implant failure due to two effects on the femoral head: biological (excessive local exothermic reaction could cause osteocyte necrosis) and biomechanical (which could lead to uneven load distribution on the femoral head).

    2003-03-01

    Purpose: To investigate the clinical and radiological characteristics of osteochondritis dissecans (OD) of the hip and the outcome of this condition after treatment. Material and Methods: Twelve male and 3 female patients with OD were retrospectively studied. Six patients had a history of Legg-Calve-Perthes disease (LCPD) and among them 2 also had had a trauma to the hip. A further 5 had had trauma and 1 a developmental dislocation of the hip (DDH). The remaining 3 patients had no history of previous hip disease or trauma. All patients were examined with plain radiography, 7 with MR, 3 with CT and 2 with hip arthrography. Results: All OD lesions were detected at plain radiography, and most of them were located near the fovea. At MR the lesions had low signal intensity at T1-weighted sequences, and 6/7 had edema or fluid collection in or adjacent to the lesion on T2-weighted sequences. The early treatment in 7 patients was surgery, 2 had had conservative treatment and 6 no treatment. At follow-up 12 years after radiological diagnosis, 5 patients had hip arthrosis, 4 of whom were treated with arthroplasty. All but 3 had reduced hip rotation and all but 2 (with arthroplasty) had load pain. Three of the patients with earlier surgery had not developed arthrosis. Conclusions: OD lesions are usually well seen with plain radiography. There is a great risk of developing early arthrosis and it seems that early surgery is connected with arthrosis development. Thus only symptomatic treatment is recommended.

    Total hip arthroplasty (THA) is an effective and durable treatment option for hip osteoarthritis (OA). As life expectancy continues to increase, so too will the demand for joint arthroplasty in the 10th decade of life, frequently in cases involving osteoarthritis of both hips. Simultaneous bilateral total hip arthroplasty (SBTHA) is a valuable therapeutic option in appropriately selected patients with bilateral degenerative hip disease, although its use in the very elderly is poorly reported on in the literature. A case of bilateral hip OA successfully treated with SBTHA in a nonagenarian is presented and the literature is reviewed.

    Microinstability and ligament teres lesions are emergent topics on the hip pathology. These entities are an increasingly recognized cause of persistent hip pain and should be considered in the differential diagnosis of the patient with hip pain. Conventional (non-arthrographic) CT and MR have a very limited role in the evaluation of these entities. CTa and MRa have emerged as the modalities of choice for pre-operative imaging of ligamentum teres injuries and microinstability. To date, pre-operative imaging detection of these pathologies is not widespread but with appropriate imaging and a high index of suspicion, preoperative detection should improve. This article discusses current concepts regarding anatomy, biomechanics, clinical findings, diagnosis and treatment of ligament teres lesions and microinstability.

    A prospective, multi-centre study was carried out on 1421 total hip replacements between January 1999 and July 2007 to examine if obesity has an effect on clinical outcomes. The patients were categorised into three groups: non-obese (body mass index (BMI) 40 kg/m(2)). The primary outcome measure was the change in Oxford hip score at five years. Secondary outcome measures included dislocation and revision rates, increased haemorrhage, deep infection, deep-vein thrombosis and pulmonary embolism, mean operating time and length of hospital stay. Radiological analysis assessing heterotopic ossification, femoral osteolysis and femoral stem positioning was performed. Data were incomplete for 362 hips (25.5%) There was no difference in the change in the Oxford hip score, complication rates or radiological changes at five years between the groups. The morbidly obese group was significantly younger and required a significantly longer operating time. Obese and morbidly obese patients have as much to gain from total hip replacement as non-obese patients.

    Hip fracture is commonly associated with an overwhelming inflammatory response, which may lead to high rates of morbidity and mortality in the elderly. MicroRNAs (miRNAs) play important roles in the functions of immune system. However, the association between miRNA dysregulation and immune disturbance (IMD) related to elderly hip fracture is largely unknown. In this study, microarray profiling was carried out to evaluate the differential expression patterns of miRNAs in plasma of the aged hip fracture rats with IMD, those without IMD, and normal aged rats, followed by validation using quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). Genes and signaling pathways of the dysregulated miRNAs related to elderly hip fracture-induced IMD were investigated in silico using Gene Ontology and analysis of Kyoto Encyclopedia of Genes or Genomes. Dead or moribund rats with hip fracture exhibited significantly reduced TNF-α/IL-10 ratio compared with healthy controls and other hip fracture rats, which were therefore named as hip fracture rats with IMD. Seven serum miRNAs in hip fracture rats with IMD were significantly downregulated. qRT-PCR and in silico analysis revealed that miR-130a-3p likely participated in regulating the hip fracture-induced IMD. Furthermore, Western blot experiment demonstrated that in lung tissue, the reduction of miR-130a-3p was accompanied with the increase of the protein expression of interferon regulatory factor-1 (IRF1) and sphingosine-1-phosphate receptor 1 (SIPR1). miR-130a-3p desregulation may be associated with elderly hip fracture-induced IMD, which might act as a new potential biomarker for the diagnosis and prognosis of elderly hip fracture-induced IMD and a potential therapeutic target as well.

    Full Text Available The authors define adolescence and developmental dysplasia of the hip (DDH. Special attention is paid to pathological findings characteristic of DDH in adolescence (unrecognized and untreated DDH; treated DDH, but non-terminated treatment; DDH diagnosed with delay, inadequately treated, with complications. The authors emphasise that DDH treatment has to be successfully terminated well before the adolescence; possibilities are explained on management modes at the time of adolescence, and possible persons guilty for the persistence of later hip problems are indicated. Based on the authors' experience and having in mind all surgical possibilities for the treatment (pelvic osteotomies, femoral osteotomies, trochanteroplasties, leg length equalization procedures the authors propose treatment protocols. The intention is to provide better treatment results and to prevent secondary hip arthrosis. Furthermore, how to improve the struggle against DDH is suggested.

    More than twenty years ago, hydroxyapatite (HA), calcium phosphate ceramics, was introduced as a coating for cementless hip prostheses. The choice of this ceramic is due to its composition being similar to organic apatite bone crystals. This ceramic is biocompatible, bioactive, and osteoconductive. These qualities facilitate the primary stability and osseointegration of implants. Our surgical experience includes the implantation of more than 4,000 cementless hydroxyapatite coated hip prostheses since 1990. The models implanted are coated with HA in the acetabulum and in the metaphyseal area of the stem. The results corresponding to survival and stability of implants were very satisfactory in the long-term. From our experience, HA-coated hip implants are a reliable alternative which can achieve long term survival, provided that certain requirements are met: good design selection, sound choice of bearing surfaces based on patient life expectancy, meticulous surgical technique, and indications based on adequate bone quality.

    2015-01-01

    Full Text Available More than twenty years ago, hydroxyapatite (HA, calcium phosphate ceramics, was introduced as a coating for cementless hip prostheses. The choice of this ceramic is due to its composition being similar to organic apatite bone crystals. This ceramic is biocompatible, bioactive, and osteoconductive. These qualities facilitate the primary stability and osseointegration of implants. Our surgical experience includes the implantation of more than 4,000 cementless hydroxyapatite coated hip prostheses since 1990. The models implanted are coated with HA in the acetabulum and in the metaphyseal area of the stem. The results corresponding to survival and stability of implants were very satisfactory in the long-term. From our experience, HA-coated hip implants are a reliable alternative which can achieve long term survival, provided that certain requirements are met: good design selection, sound choice of bearing surfaces based on patient life expectancy, meticulous surgical technique, and indications based on adequate bone quality.

    Full Text Available Rose hip, also known as wild rose, is a summer fruit. The aim of this research is to present physical, chemical, rheological, sensory and antioxidant properties of rose hip marmalades. Rose hips cultivated in Turkey are processed into pulp and then marmalade is made by using vacuum evaporator or classical method. For the purposes of this investigation, marmalades produced on a factory scale using two methods were compared to commercial marmalades purchased on market. The marmalades exhibited high levels of antioxidant activity as well as total phenolic content. The consistency indices for the marmalades were determined to be between 64.2 and 321 Pa·s^n. Colour parameters, namely L, a, b, were measured and correlations between the examined parameters were calculated.

    Fast-track surgery implies a coordinated perioperative approach aimed at reducing surgical stress and facilitating post-operative recovery. The fast-track programme has reduced post-operative length of stay and has led to shorter convalescence with more rapid functional recovery and decreased morbidity and mortality in total hip arthroplasty. It should now be a standard total hip arthroplasty patient pathway, but fine tuning of the multiple factors in the fast-track pathway is still needed in patients with special needs or high comorbidity burden.

    Traumatic hip dislocation is a rare event in children. Appropriate management remains a subject of debate. The purpose of this study was to investigate the epidemiological, therapeutic features of this situation and the long-term outcome after treatment. This was a retrospective analysis of 15 traumatic hip dislocations collected over a period of 20 years in pediatric patients with at least two years follow-up. We searched for predisposing factors and factors affecting prognosis. The series included 11 boys and three girls, mean age eight years. Dislocation was posterior in 13 hips and anterior in two. Time to reduction was less than 3h in eight cases, 3-6h in five and greater than 6h in two. After reduction, traction was performed in nine children, for 20 days on average, followed in five cases by immobilization for 40 days on average. Five hips were immobilized directly after reduction. We identified two groups by age: group 1 with dislocations in children aged less than six years (seven children) were characterized by low-energy trauma. Dislocation was not associated with other lesions. Predisposing factors (overt ligament hyperlaxity, insufficient superolateral head cover, coax valga) were noted in six children. Reduction was simple. Later treatment consisted in immobilization with a pelvispedious cast for 30-45 days. Group 2 were dislocations in children aged over six years (seven children) victims of high-energy trauma. Associated injuries were frequent. Predisposing factors were not present. At mean 11 years follow-up, all hips are considered normal clinically. The radiograph was normal for 14 hips. In one case, there was a slight coax magna. In three patients, defective femoral head cover persisted. Coxa valga persisted in two patients. Traumatic dislocation of the hip joint is rare in very young children, but results from a minimally traumatic event. This suggests the presence of predisposing factors in this category of patients, particularly

    To determine patient- and surgery-specific characteristics of patients sustaining postarthroscopic hip dislocation or subluxation. A systematic review of multiple medical databases was registered with PROSPERO and performed using Preferred Reporting Items for Systemic Reviews and Meta-Analysis guidelines. Level I to IV clinical outcome studies reporting the presence of hip dislocation or subluxation after hip arthroscopy were eligible. Length of follow-up was not an exclusion criterion. All patient- and surgery-specific variables were extracted from each, specifically evaluating osseous morphology and resection details; labral, iliopsoas, ligamentum teres, and capsular management; generalized ligamentous laxity; instability direction and mechanism; management; and outcome. Study authors were individually contacted to assess most recent outcome. Ten articles with 11 patients were analyzed (mean patient age: 36.6 ± 12.3 years). There were 9 hip dislocations and 2 subluxations. Mean time between surgery and dislocation was 3.2 ± 4.0 months (range: recovery room to 14 months). Anterior was the most frequent dislocation direction (8 cases). Acetabular undercoverage (preoperative dysplasia or iatrogenic rim over-resection) was observed in 5 cases. Labral debridement was performed in 5 cases, iliopsoas tenotomy in 3 cases, and ligamentum teres debridement in 1 case. A "T" capsulotomy was created in 1 case (isolated interportal in other 10 cases). Capsular closure was performed in 2 cases (both interportal). Generalized ligamentous laxity was diagnosed in 1 case. A combination of external rotation and extension was observed in 5 of the 6 cases reporting the mechanism of anterior dislocation. Four cases were successfully treated with closed reduction; 4 required total hip arthroplasty; and 3 required revision capsulorrhaphy. Postarthroscopic hip instability was observed in patients with acetabular undercoverage (including iatrogenic resection), labral debridement

  1. Adventure sports and sexual freedom hip replacement: the tripolar hip.

    2017-06-28

    Certain athletic activities and lifestyles require a completely stable and very mobile hip. Total hip replacement with a natural femoral head size and two mobile-bearing surfaces (i.e., a "tripolar" prosthesis) is the most stable prosthesis. Elegant design and wear-resistant bearing surfaces are the keys to long-term implant survivorship. The hypothesis is that a ceramic-coated tripolar prosthesis using highly cross-linked polyethylene can provide full function and complete stability with low wear. This study sought to determine: (1) patient-reported outcomes, (2) functional outcomes, (3) implant survivorship and complications, and (4) postoperative sexual limitations. Between 1998 and 2011, the author performed 160 primary total hip replacements using tripolar prostheses in patients participating in adventure sports and other physically demanding activities. The institutional review board approved this study. The inclusion criteria were patients who needed unrestricted activity and who were not candidates for or did not choose hip resurfacing. Patients were followed every second year and assessed with radiographs, Harris Hip Score, WOMAC, SF-12, and UCLA functional outcome scores. Patients were asked about symptoms of instability and satisfaction with their hip replacement. Patients were asked both preoperatively and 2 years postoperatively four questions about their sexual activity. Mean follow-up was 11 years. At 2 years' postoperatively, 98% of patients reported their satisfaction as excellent or good and 99% were not limited for sexual activity following surgery. Seventy-four percent of patients reported they were recovered within 6 weeks of surgery. There were no dislocations. There were three revision procedures for implant loosening, infection, and periprosthetic fracture, but there were no failures of the tripolar articulation. The mean postoperative UCLA score was the highly athletic score of 8. There were no signs of osteolysis, wear, or metal

    Full Text Available Osteoporosis is epidemic in Asian countries. It is a major cause of fractures that orthopaedic surgeons deal in Pakistan, though proper epidemiological data is not available. Habiba U et al found that 75.3% of post menopausal women of Pakistan were predisposed to Osteoporosis; whereas Baig L has described an average T - score of -1.833±0.65 on bone mineral density calculation of post menopausal females of Pakistan. Osteoporotic hip fractures constitute a major cause of elderly mortality worldwide and recent figures supporting the idea that these patients have survival rates comparable to breast and thyroid cancer patients. Pakistan is a developing country with large burden of hip fractures. Patients living in remote areas are the ones which suffer more because of inadequate awareness, fear of surgical treatment and lack of availability of standard treatment. These patients are dealt by surgeons of various expertise and levels of experience. Lack of facilities in hospitals is well known and usage of sub-standard implant is a major cause of failure. Therefore these patients either because of their bone fragility or mal-treatment suffer frequently from failure of hip fracture surgeries. Being in a tertiary care centre we come across these types of cases very frequently. Six to eight such cases present to outpatient department of Liaquat National Hospital every month being referred from every part of the country. These patients may have been operated once, twice or even multiple times. Special attention is required to acquire an informative history from these cases and perform a comprehensive examination. Moreover previous records and radiographs provide invaluable information regarding cause of failure and deciding course of further treatment. We herein discuss few of the cases of failure of hip fractures which were treated by hip arthroplasty.

    The Mycobacterium tuberculosis (Mtb) serine protease Hip1 (hydrolase important for pathogenesis; Rv2224c) promotes tuberculosis (TB) pathogenesis by impairing host immune responses through proteolysis of a protein substrate, Mtb GroEL2. The cell surface localization of Hip1 and its immunomodulatory functions make Hip1 a good drug target for new adjunctive immune therapies for TB. Here, we report the crystal structure of Hip1 to a resolution of 2.6 Å and the kinetic studies of the enzyme against model substrates and the protein GroEL2. The structure shows a two-domain protein, one of which contains the catalytic residues that are the signature of a serine protease. Surprisingly, a threonine is located within the active site close enough to hydrogen bond with the catalytic residues Asp463 and His490. Mutation of this residue, Thr466, to alanine established its importance for function. Our studies provide insights into the structure of a member of a novel family of proteases. Knowledge of the Hip1 structure will aid in designing inhibitors that could block Hip1 activity

    Hip or groin pain in athletes is common and clinical presentation is often nonspecific. Imaging is a very important diagnostic step in the work-up of athletes with hip pain. This review article provides an overview on hip biomechanics and discusses strategies for hip imaging modalities such as radiography, ultrasonography, computed tomography, and magnetic resonance (MR) imaging (MR arthrography and traction MR arthrography). The authors explain current concepts of femoroacetabular impingement and the problem of high prevalence of cam- and pincer-type morphology in asymptomatic persons. With the main focus on MR imaging, the authors present abnormalities of the hip joint and the surrounding soft tissues that can occur in athletes: intraarticular and extraarticular hip impingement syndromes, labral and cartilage disease, microinstability of the hip, myotendinous injuries, and athletic pubalgia.

    2016-11-01

    Full Text Available While hip arthroscopy grows in popularity, there are still many circumstances under which open hip preservation is most appropriately indicated. This article specifically reviews open hip preservation procedures for a variety of hip conditions. Femoral acetabular impingement may be corrected using an open surgical hip dislocation. Acetabular dysplasia may be corrected using a periacetabular osteotomy. Acetabular protrusio may require surgical hip dislocation with rim trimming and a possible valgus intertrochanteric osteotomy. Legg-Calve ́-Perthes disease produces complex deformities that may be better served with osteotomies of the proximal femur and/ or acetabulum. Chronic slipped capital femoral epiphysis (SCFE may also benefit from a surgical hip dislocation and/or proximal femoral osteotomy.

    2014-01-01

    Lifestyle factors play a role in both the genesis and recovery from fragility fracture. The purpose of this review is to summarize recent evidence for exercise and nutrition in the management of hip fracture. Recent randomized controlled trials of exercise have primarily consisted of isolated resistance training or multimodal home-based programs. More robust, long-term, or supervised training is generally associated with greater clinical benefits, including muscle strength, mobility, and function. Recent nutritional interventions have included multinutrient supplements, nutritional counseling and support, and vitamin D/calcium supplementation. Isolated nutritional interventions have not consistently shown significant impact on long-term outcomes after hip fracture, although improvements in body weight, biochemical indices, complication rates, and mobility have been reported. Overall, there is marked heterogeneity in the robustness of responses seen to hip fracture treatment studies. Few large, long-term, multicomponent interventions with clinically relevant outcomes of functional independence, need for residential care, mortality, and quality of life have been reported. Evidence-based approaches to hip fracture should include comprehensive risk-factor assessment and treatment for sarcopenia/dynapenia, balance impairment, undernutrition of protein, energy, vitamin D and calcium, depression, cognitive impairment, sensory impairment, social isolation, and comorbid illness with exercise, nutrition and other modalities.

    Full Text Available Introduction. Pathological dislocation of the hip is one of the most severe complications of acute hematogenous osteomyelitis. The program of treatment for children with pathological hip dislocation is complex, but it has been sufficiently developed and implemented very successfully. At the same time, the available literature provides no cases of treating children with bilateral pathological hip dislocations after hematogenous osteomyelitis. There is no information on the incidence of such cases or in regards to remote functional results. Materials and methods. The results of the treatment of 18 children with bilateral pathological dislocation of the hip after hematogenous osteomyelitis are presented, which constituted 23.1% of the total number of patients (78 who underwent surgery in 2000–2016 for the diagnosis of pathological hip dislocation. Both hip joints were surgically operated on in 12 patients, while one hip joint was operated on in 6 patients. To assess the anatomical and functional state of hip joints, the clinical and roentgenological diagnostic techniques were used. Results and discussion. To stabilize and restore the function of the hip joints, 18 children underwent 30 surgical interventions: simple open hip reduction (19 and open hip reduction with hip arthroplasty with one (6 or two (5 demineralized osteochondral allogeneic grafts. The decision regarding the possibility of performing surgical intervention on the second hip joint was made only after a child's check-up examination was complete and after positive information about the anatomical and functional state of the operated hip joint was obtained. According to these criteria, 14 (77.8% children underwent surgical treatment of the second hip joint 1–1.5 years after the course of conservative measures to restore the range of motion in the previously operated hip joint. Over a period of 1–12 years, 17 patients were examined, 10 of which underwent an operation on both

    2015-01-01

    Full Text Available Idiopathic chondrolysis is a rare condition characterized by the ultimate loss of femoroacetabular articular cartilage seen in a child with no history of trauma, slipped capital femoral epiphysis, infection, prolonged immobilization, or any other previously described disorder. The diagnosis is often delayed secondary to the insidious onset of symptoms, progressive radiographic findings, and the absence of diagnostic laboratory test. Typical radiographic features include localized osteoporosis, subchondral erosions, femoral head changes, and reduction of the joint space. Later changes include complete loss of the joint space, subchondral cysts, trochanteric and epiphyseal physeal closure, osteophytes, and in severe cases, protrusio acetabuli, ankylosis, and osteoarthritis. Magnetic resonance imaging of the hip demonstrates cartilage loss, joint effusion, marrow edema, femoral and acetabular remodeling, significant regional muscle atrophy, and synovial enhancement. We report a case of Idiopathic chondrolysis of the hip in an 11-year-old Indian girl.

    Hip-adductor strains are among the most common lower-extremity injuries sustained in athletics. Treatment of these injuries involves a variety of exercises used to target the hip adductors. To identify the varying activation levels of the adductor longus during common hip-adductor exercises. Descriptive study. Laboratory. 24 physically active, college-age students. None. Peak and average electromyographic (EMG) activity of the adductor longus muscle during the following 6 hip-adductor rehabilitation exercises: side-lying hip adduction, ball squeezes, rotational squats, sumo squats, standing hip adduction on a Swiss ball, and side lunges. The side-lying hip-adduction exercise produced more peak and average activation than any other exercise (P Ball squeezes produced more peak and average activation than rotational squats, sumo squats, and standing adduction on a Swiss ball (P Ball squeezes had more average activation than side lunges (P = .001). All other variables for peak activation during the exercises were not statistically significant (P > .08). These results allowed the authors to provide an overall ranking system (highest to lowest muscle activation): side-lying hip adduction, ball squeezes, side lunges, standing adduction on a Swiss ball, rotational squats, and sumo squats. The study provides a ranking system on the activation levels of the adductor longus muscle for 6 common hip-adductor rehabilitation exercises, with the side-lying hip-adduction and ball-squeeze exercises displaying the highest overall activation.

    The study "Contribution of the Pubofemoral Ligament to Hip Stability: A Biomechanical Study" by Martin, Khoury, Schröder, Johnson, Gómez-Hoyos, Campos, and Palmer found that cutting the hip capsular ligament allowed a large increase in femoral internal rotation, particularly in the flexed hip, causing subluxation to occur. In addition to providing new data on the role of the pubofemoral ligament, it raises the question of whether hip joint surgeons should repair the capsule-what are the likely consequences?-and whether any beneficial effects persist in long-term clinical follow-ups. For now, hip capsular repair seems a sound adjunct to hip arthroscopic surgery. Copyright © 2016 Arthroscopy Association of North America. Published by Elsevier Inc. All rights reserved.

    Although clinicians recognize hip involvement, which frequently leads to hip replacement surgery, as an important feature of AS, data on the epidemiology, nature of the disease and therapeutic strategies are scarce. We aimed to describe the epidemiology of clinical and radiological hip involvement and define the risk factors for the hip replacement surgery in AS patients. Data from 3 datasets were merged, including 847 Belgian (ASPECT database), 1405 Spanish (REGISPONSER database) and 466 Ibero-American (RESPONDIA database) AS patients. The ASPECT and REGISPONSER database (Dataset A) are used for exploratory analysis; the RESPONDIA database (Dataset B) is used for confirmative analysis. Factors associated with hip involvement and the hip replacement surgery were analysed. Twenty four (REGISPONSER) to 36% (RESPONDIA) of AS patients under rheumatologist's care presented clinical hip involvement, including the 5% (Dataset A) of AS patients who needed hip replacement surgery. Patients with hip involvement had significantly worse overall Bath Ankylosing Spondylitis Functional Index (BASFI) scores compared with patients without hip involvement (mean difference = 1.6, P < 0.001) (Dataset A, confirmed in B). Corrected for disease duration, patients with early disease onset, enthesial and axial disease needed most frequently hip replacement surgery (Dataset A, confirmed in B). Hip involvement is commonly recognized by rheumatologists in AS patients, and involves about one out of the three to four patients with AS and is associated with impaired functioning reflected by higher overall BASFI scores. Early onset of disease, axial and enthesial disease are associated with the hip replacement surgery in AS.

    2011-09-01

    Full Text Available Several factors seem to play a relevant role in the pathogenesis of hip osteoarthritis. Among these, an altered biomechanic and neuromuscular integrity of the hip joint should be considered. This is a review of the recent international literature concerning the role of loads and strengths acting on the hip joint, in order to better understand the pathogenesis and the physiopathology of the hip osteoarthritis. The study of these factors might be important to prevent the development of the osteoarthritis and might suggest the conservative treatment. In particular, the role of the balance among the muscles working in maintaining the equilibrium of the acting strengths is matter of discussion. The articular and neuromuscular dysfunction might induce an altered load distribution in the hip, particularly on the articular cartilage surface, and seems to favour the development of hip osteoarthritis...

    Dendritic cells (DCs) play a key role in the generation of CD4 T cell responses to pathogens. Mycobacterium tuberculosis (Mtb) harbors immune evasion mechanisms that impair DC responses and prevent optimal CD4 T cell immunity. The vaccine strain Mycobacterium bovis Bacille Calmette-Guérin (BCG) shares many of the immune evasion proteins utilized by Mtb, but the role of these proteins in DC and T cell responses elicited by BCG is poorly understood. We previously reported that the Mtb serine protease, Hip1, promotes sub-optimal DC responses during infection. Here, we tested the hypothesis that BCG Hip1 modulates DC functions and prevents optimal antigen-specific CD4 T cell responses that limit the immunogenicity of BCG. We generated a strain of BCG lacking hip1 (BCGΔhip1) and show that it has superior capacity to induce DC maturation and cytokine production compared with the parental BCG. Furthermore, BCGΔhip1-infected DCs were more effective at driving the production of IFN-γ and IL-17 from antigen-specific CD4 T cells in vitro. Mucosal transfer of BCGΔhip1-infected DCs into mouse lungs induced robust CD4 T cell activation in vivo and generated antigen-specific polyfunctional CD4 T cell responses in the lungs. Importantly, BCGΔhip1-infected DCs enhanced control of pulmonary bacterial burden following Mtb aerosol challenge compared with the transfer of BCG-infected DCs. These results reveal that BCG employs Hip1 to impair DC activation, leading to attenuated lung CD4 T cell responses with limited capacity to control Mtb burden after challenge. ©2017 Society for Leukocyte Biology.

    Total hip replacement (THR) is the treatment of choice for the patient suffering from end-stage hip osteoarthritis. In the presence of deformities due to congenital hip disease (CHD), THR is, in most of the cases, a difficult task, since the technique of performing such an operation is demanding and the results could vary. We present our experience and preferred strategies focusing on challenges and surgical techniques associated with reconstructing the dysplastic hip.

    2013-08-01

    Ankylosing spondylitis (AS) is an inflammatory rheumatologic disease characterized by inflammation and progressive structural damage of the affected joints. Hip involvement often results in severe deformities and significant impairment on function. Although, tremendous progress has been made in conservative management for AS, effective prevention strategies for hip involvement and long-term need for total hip arthroplasty (THA) remain indefinite. When hip involvement has progressed to intractable pain and disability, THA is still the most effective treatment strategy to relieve pain and restore function. However, certain AS-specific problems regarding "preoperative preparation," "intraoperative difficulties," "perioperative pharmacological management," "postoperative physiotherapy," "operation benefits," and "operation complications" need more concern and further discussion.

    Imaging of hip cartilage is challenging because of its limited thickness and complex geometry and therefore requires advanced MRI techniques. However, cartilage abnormalities are found in a number of disease entities, and their diagnosis may impact patient management. This article will provide pertinent information about the motivation to image hip cartilage, which imaging techniques to use, and how to analyze cartilage; finally, we will discuss disease entities with regional cartilage lesions, including the typical MRI findings. Because the detection and quantification of regional cartilage abnormalities are critical for guidance of operative and nonoperative management of hip disorders, radiologists should be familiar with imaging and analysis techniques for assessing hip cartilage.

    Full Text Available Introduction: In relation to the study reporting the effects of applying phased complex rehabilitation in patients with total hip arthroplasty, it has been concluded that the everyday clinical practice in Bulgaria does not apply complex examination, giving an objective picture about the extent of functional status of patients with trauma and diseases of the hip. Aim: The main goal of this report is to present a test which incorporates all known and routine research and in which the total number of points determines the functional status of patients with trauma and diseases of the hip. Material and Methods: Based on the Hip dysfunction and Osteoarthritis Outcome Score, the Harris Hip Score modified test, scale D’Aubigne and Postel and Iowa’s test for complex functional evaluation of the hip joint, we have developed a test including information about the degree of pain; goniometry and manual muscle testing of the hip; locomotor test – type of gait and adjuvants; test for Daily Activities of Life. The test has been developed on the basis of expert assessment by doctors and physiotherapists of the proposed indicators for evaluation and determination of the weighting factors’ contribution to the general condition of the patient. Conclusion: The developed and tested method of complex functional assessment of the hip joint enables our colleagues, dealing with trauma and diseases of the hip, to use it in various research and scientific projects, as well as in general medical practice.

    The objective of this study was to compare a cohort of geriatric patients with operatively managed isolated fractures below the hip to a cohort of geriatric patients with operatively managed isolated hip fractures. All patients greater than 59 years of age admitted to our institution for surgical care of an isolated lower extremity fracture during a 3-year period were included. Patients were divided into 2 cohorts: BTH (fracture below the subtrochanteric region of the femur) and HIP (proximal femoral fracture at subtrochanteric region or proximal). We identified 141 patients included in cohort BTH and 205 patients included in cohort HIP. HIP patients were older (P patients and of peripheral neuropathy (P = .014) in BTH patients. HIP patients were more likely to be under active antiosteoporotic medication management and were more likely to be receiving pharmacological anticoagulation at the time of admission. HIP patients and BTH patients were similar with regard to necessity of assistance with ambulation preinjury, but HIP patients were less likely to reside independently at home than were BTH patients (P patients were also less likely to be discharged directly home from the hospital (P Geriatric patients with fractures below the hip are medically similar to geriatric patients with hip fracture. Medical comanagement protocols have been extensively published that improve care of geriatric patients with hip fracture; consideration should be given to similar protocol-driven medical comanagement programs for geriatric patients with fractures below the hip.

    Hypochlorhydria during Helicobacter pylori infection inhibits gastric Sonic Hedgehog (Shh) expression. We investigated whether acid-secretory mechanisms regulate Shh gene expression through intracellular calcium (Ca2(+)(i))-dependent protein kinase C (PKC) or cyclic adenosine monophosphate (cAMP)-dependent protein kinase A (PKA) activation. We blocked Hedgehog signaling by transgenically overexpressing a secreted form of the Hedgehog interacting protein-1, a natural inhibitor of hedgehog ligands, which induced hypochlorhydria. Gadolinium, ethylene glycol-bis(β-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA) + 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid (BAPTA), PKC-overexpressing adenoviruses, and PKC inhibitors were used to modulate Ca(2+)(i)-release, PKC activity, and Shh gene expression in primary gastric cell, organ, and AGS cell line cultures. PKA hyperactivity was induced in the H(+)/K(+)-β-cholera-toxin-overexpressing mice. Mice that expressed secreted hedgehog-interacting protein-1 had lower levels of gastric acid (hypochlorhydria), reduced production of somatostatin, and increased gastrin gene expression. Hypochlorhydria in these mice repressed Shh gene expression, similar to the levels obtained with omeprazole treatment of wild-type mice. However, Shh expression also was repressed in the hyperchlorhydric H(+)/K(+)-β-cholera-toxin model with increased cAMP, suggesting that the regulation of Shh was not solely acid-dependent, but pertained to specific acid-stimulatory signaling pathways. Based on previous reports that Ca(2+)(i) release also stimulates acid secretion in parietal cells, we showed that gadolinium-, thapsigargin-, and carbachol-mediated release of Ca(2+)(i) induced Shh expression. Ca(2+)-chelation with BAPTA + EGTA reduced Shh expression. Overexpression of PKC-α, -β, and -δ (but not PKC-ϵ) induced an Shh gene expression. In addition, phorbol esters induced a Shh-regulated reporter gene. Secretagogues that stimulate

    Full Text Available Abstract Background There have been reports both supporting and refuting an inverse relationship between hip fracture and hip osteoarthritis (OA. We explore this relationship using a case-control study design. Methods Exclusion criteria were previous hip fracture (same side or contralateral side, age younger than 60 years, foreign nationality, pathological fracture, rheumatoid arthritis and cases were radiographic examinations were not found in the archives. We studied all subjects with hip fracture that remained after the exclusion process that were treated at Akureyri University Hospital, Iceland 1990-2008, n = 562 (74% women. Hip fracture cases were compared with a cohort of subjects with colon radiographs, n = 803 (54% women to determine expected population prevalence of hip OA. Presence of radiographic hip OA was defined as a minimum joint space of 2.5 mm or less on an anteroposterior radiograph, or Kellgren and Lawrence grade 2 or higher. Possible causes of secondary osteoporosis were identified by review of medical records. Results The age-adjusted odds ratio (OR for subjects with hip fracture having radiographic hip OA was 0.30 (95% confidence interval [95% CI] 0.12-0.74 for men and 0.33 (95% CI 0.19-0.58 for women, compared to controls. The probability for subjects with hip fracture and hip OA having a secondary cause of osteoporosis was three times higher than for subjects with hip fracture without hip OA. Conclusion The results of our study support an inverse relationship between hip fractures and hip OA.

    The objective of this study was to define, in unilateral hip osteoarthritis (OA), factors predicting the outcome of the other hip. We examined the anteroposterior radiographs of the pelvis of 95 white patients with unilateral idiopathic (56 patients) or secondary to congenital hip diseases (39 patients) OA. The other hip was free from symptoms (pain or limping) at the initial examination and without radiographic evidence of OA; it was what we call a ''normal'' hip. Two parameters were evaluated: (1) the type of osteoarthritis of the involved hip and (2) the range of four radiographic indices of the contralateral hip: the sourcil inclination (weight-bearing surface), the acetabular angle, the Wiberg's center-edge angle, and the neck-shaft angle. Follow-up radiographs for the hips that remained OA-free were available for 10 to 35 years and for those that developed OA, at the time of initial symptoms, range 2 to 31 years. Logistic regression analysis showed that the presence of idiopathic OA in one hip had a statistically significant effect on the development of OA on the other hip (p<0.001). Minor deviations of radiographic indices of the contralateral hip is not a predictive factor for its outcome. When the radiographic indices are examined together with the pathology of the involved hip, only WBS was shown to have a significant effect to the development of OA and its type (p < 0.001). The following conclusions can be drawn from this study: 1. Patient with idiopathic OA of one hip is at increased risk of developing OA in the other hip. 2. The outcome of the other hip cannot be predicted only on the basis of the evaluation of its radiographic indices. 3. Among the different indices, WBS seems to have a strong influence toward the development of OA. (orig.)

    We examined the effects of hip fracture on mortality, entry into long-term institutional care, and new evidence of poverty. We estimate of the proportion of hip fracture patients who require not just short-term rehabilitation but who become dependent on long-term institutional care, and the risk of becoming newly dependent on Medicaid or eligible for low-income subsidies following hip fracture. We used data from 2005 through 2010 for a random 5% sample of Medicare beneficiaries (N = 3.1 million) to conduct a retrospective matched cohort study. We used high-dimensional propensity score matching to compare outcomes for patients who experienced a hip fracture with subjects who did not, but had similar propensity for suffering a hip fracture. We then compared the 1-year risk of death, debility, and destitution between groups. We matched 43,210 hip fracture patients to comparators without a hip fracture. Hip fractures were associated with more than a twofold increase in likelihood of mortality (incidence proportion ratio [IPR] of 2.27, 95% CI, 2.20-2.34), a fourfold increase in likelihood of requiring long-term nursing facility care (IPR, 3.96; 95% CI, 3.77-4.16), and a twofold increase in the probability of entering into low-income status (IPR, 2.14; 95% CI 1.99-2.31) within 1 year following hip fracture compared with subjects without a hip fracture. Hip fracture in elderly patients resulted in increased death, debility, and destitution. Initiatives that lead to improved treatment of osteoporosis could result in a decrease in incidence of fractures, subsequent death, debility, and destitution for older adults.

    Jogging has been classified as a high-impact sport, and jogging after total hip arthroplasty (THA) has not been well documented. To investigate the participation rate for postoperative jogging as well as jogging parameters and the influence of jogging on implant stability and bearing wear. Case-control study; Level of evidence, 3. Included in this study were 804 hips in 608 patients (85 men, 523 women) who underwent THA between 2005 and 2011 with follow-up longer than 1 year. The mean patient age was 62 years (range, 26-98 years), and mean follow-up duration was 4.8 years (range, 2.3-7.8 years). Hip resurfacing arthroplasty (HRA) was performed in 81 patients and conventional THA in 527 patients. During routine postsurgical visits, patients were given a questionnaire concerning preoperative and postoperative jogging routines. For joggers, frequency, distance, duration, and velocity of jogging were recorded. Patients who did not jog postoperatively were asked to provide reasons for not jogging. Radiographs concerning implant migration and polyethylene wear were evaluated with specialized software, and serum cobalt and chromium ion concentrations were investigated for patients with metal-on-metal articulation. A total of 33 patients (5.4%) performed jogging preoperatively, and 23 patients (3.8%) performed jogging postoperatively. Of the 23 who jogged postoperatively, conventional THA was performed in 13 patients and HRA in 10 patients. Postoperatively, joggers trained a mean of 4 times (range, 1-7 times) per week, covering a mean distance of 3.6 km (range, 0.5-15 km) in a mean time of 29 minutes (range, 5-90 minutes) per session and at a mean speed of 7.7 km/h (range, 3-18 km/h). No patient complained of pain or showed serum cobalt and chromium ion elevation greater than 7 ppb. No hip showed loosening, abnormal component migration, or excessive wear at a mean 5-year follow-up. There were 74 postoperative non-joggers with an interest in jogging. The reasons given for

    Hip dysplasia (HD) is a common orthopedic condition seen in small animal patients that leads to osteoarthritis of the coxofemoral joint. The disease can be managed conservatively or surgically. The goals of surgical treatment in the immature patient are to either prevent the clinical signs of HD or to prevent or slow the progression of osteoarthritis. In mature patients surgery is used as a salvage procedure to treat debilitating osteoarthritis. Conservative management can be used in dogs with mild or intermittent clinical signs and includes nutritional management and weight control, exercise modification, physical rehabilitation, pain management and disease-modifying agents.

    Hot Isostatic Pressing (HIP) is investigated as a technique for joining the cermet WC-15% Co to itself. Encapsulation of the specimens prior to HIPing was carried out using steel encapsulation, glass encapsulation and self encapsulation. The bonds were evaluated using a four point bend method. It is shown that the glass and steel encapsulation methods have a number of inherent problems which make them inappropriate for near net shape processing. In contrast the novel self encapsulation method, described for the first time in this communication, is both simple and effective, producing joined material with bulk strength. The concept of self encapsulation is potentially widely applicable for joining composite materials.

    To study the hip muscle strength and cross sectional area (CSA) in men with hip osteoarthritis (OA) compared to age and sex matched healthy controls. Based on the American College of Rheumatology criteria regarding classification of hip OA, 27 men (aged 47-64 yrs) with unilateral or bilateral hip OA and 30 age matched randomly selected healthy male controls were studied. The maximal isometric hip abductor, adductor, flexor, and extensor strength (Nm) at 0 degree of hip flexion in the supine position was determined with a dynamometer. The isokinetic hip flexion and extension strength (peak torque, Nm) was determined using angular velocities of 60 degrees /s and 120 degrees /s. The subjective severity of hip pain was rated by visual analog scale prior to the muscle strength test. CSA of the pelvic and thigh muscles was measured from magnetic resonance images. The reliability of intraclass correlation coefficients for repeated measures of muscle strength varied from 0.70 to 0.94 in controls and from 0.84 to 0.98 in subjects with OA. Hip isometric adductor and abductor strength was 25% and 31% lower (p muscles did not differ between the groups. However, in OA subjects, the CSA of the pelvic and thigh muscles was 6-13% less (p muscle strength than controls. The decrease of muscle size and hip pain may contribute to the decrease of muscle strength in hip OA. Other possible underlying causes of the muscle weakness need to be studied.

Postmenopausal women suffering earlier non-hip fractures have an increased risk of later hip fracture. The relative risk being highest within the first years following the fracture. Nursing home residents...... have a high risk of hip fracture (annual rate of 5-6%), and the incidence of falls is about 1,500 falls/1,000 persons/year. Most hip fractures are a result of a direct trauma against the hip. The incidence of falls on the hip among nursing home residents is about 290 falls/1,000 persons/year and about...... the hip may influence the risk of hip fracture, and being an important determinant for the development of hip fracture, maybe more important than bone strength. External hip protectors were developed and tested in an open randomised nursing home study. The rate of hip fractures was reduced by 50...

    Pertunjukan Teater Karo Hip Hop Kontemporer KAI. The performance of Karo Theater collaborated with Hip Hop stems from a simple idea to collaborate Karo cultural traditions with popular culture. The performances can be enjoyed without having limitation on the language and culture. The process of combining two different cultures is a form of hybrid culture, and it may occur due to the globalization process. Through the process of deposition of the observations and strong impression, this performance is then brought into the form of Hip Hop as a preferred form which is energetic, personal and global. This performance is part of a modern tragedy with its destructive character which has explored the emotion and has presented it to the audiences. The exploration of Karo cultural tradition and Hip Hop dance as a language of symbols is able to reinforce words. The movement is not revealed by the verbal phrase but is presented through the movement of Hip Hop dance. The interpretation of the legend and texts into movement is carried out through the training process at the laboratory as a searching process and experiment, and afterward can be realized by considering the basic elements of Hip Hop, Karo cultural elements and performance. Karo Hip Hop Theatre is expected to become a preferred aesthetic form of a modern theater without losing its tradition form. Keyword: a contemporary Karo theater, Hip Hop, hybrid culture.

    Full Text Available Congenital hip luxation is a disorder which evolves in time. Teratological hip dislocation is a distinct form of hip luxation, which usually appears with other disorders. These hips are dislocated before birth. In this thesis we will try to elaborate a recovery program, through physical exercises, which will help us realize our treatment objectives: diminishing articular stiffness, increasing articular mobility, increasing muscle strength, recalibration of agonist and antagonist balances and reeducating gait. The specific objectives of the study consist of the particularization of the recovery programs based on age, illness stage (dysplasia or luxation and either surgical or non-surgical intervention. To show the importance of physiotherapy in gait rehabilitation of a child with hip dislocation we started from the hypothesis: using an adequate rehabilitation program after an individualized methodology, optimizes the functional recovery and ensures the gains of hip stability and the formation of an engram of gait as close as it could be to the normal one. We present a case of neurological congenital hip dislocation where the treatment initiated early is showing good results. Results obtained are significantly different and we came to the conclusion that starting an untimely analytical kinetic treatment and globally personalizing it to every patient has better biomechanical results for the hip.

    It is not known whether postsurgery systemic inflammation and plasma amino acid abnormalities are still present during rehabilitation of individuals after elective hip arthroplasty (EHA). Sixty subjects (36 females; age 66.58 ± 8.37 years) were randomized to receive 14-day oral EAAs (8 g/day) or a placebo (maltodextrin). At admission to and discharge from the rehabilitation center, serum C-reactive protein (CRP) and venous plasma amino acid concentrations were determined. Post-EHA hip function was evaluated by Harris hip score (HHS) test. Ten matched healthy subjects served as controls. At baseline, all patients had high CRP levels, considerable reduction in several amino acids, and severely reduced hip function (HHS 40.78 ± 2.70 scores). After treatment, inflammation decreased both in the EAA group and in the placebo group. Only EAA patients significantly improved their levels of glycine, alanine, tyrosine, and total amino acids. In addition, they enhanced the rate of hip function recovery (HHS) (from baseline 41.8 ± 1.15 to 76.37 ± 6.6 versus baseline 39.78 ± 4.89 to 70.0 ± 7.1 in placebo one; p = 0.006). The study documents the persistence of inflammation and plasma amino acid abnormalities in post-EHA rehabilitation phase. EAAs enhance hip function retrieval and improve plasma amino acid abnormalities. PMID:27110573

    Full Text Available Osteoporotic hip fracture (HF is a serious global public health problem associated with high morbidity and mortality. Hip bone size (BS has been identified as one of key measurable risk factors for HF, independent of bone mineral density (BMD. Hip BS is highly genetically determined, but genetic factors underlying BS variation are still poorly defined. Here, we performed an initial genome-wide copy number variation (CNV association analysis for hip BS in 1,627 Chinese Han subjects using Affymetrix GeneChip Human Mapping SNP 6.0 Array and a follow-up replicate study in 2,286 unrelated US Caucasians sample. We found that a copy number polymorphism (CNP267 located at chromosome 2q12.2 was significantly associated with hip BS in both initial Chinese and replicate Caucasian samples with p values of 4.73E-03 and 5.66E-03, respectively. An important candidate gene, four and a half LIM domains 2 (FHL2, was detected at the downstream of CNP267, which plays important roles in bone metabolism by binding to several bone formation regulator, such as insulin-like growth factor-binding protein 5 (IGFBP-5 and androgen receptor (AR. Our findings suggest that CNP267 region may be associated with hip BS which might influence the FHL2 gene downstream.

    The aim of this study was to evaluate the impact of dancing on hip joint mobility and to assess the relationship between active movements of the hips and injuries among dancers, which may be important in planning rehabilitation in this group. The sample comprised 49 dancers (37 women and 12 men) aged 15 to 32 years. The participants were the professional dancers of the Kielce Dance Theatre and members of two youth jazz dance teams from the Kielce Dance Theatre. The active range of motion of the hips was measured in three planes using a goniometer in order to assess the influence of dance training on hip joint mobility. A questionnaire-based survey was also conducted. The range of flexion, extension and external rotation was significantly greater in the group of long-time dancers (p gender were associated with an increased range of hip joint motion.

    Hip fracture is the most serious complication of osteoporosis and the incidence is rising worldwide. Bone mineral density measurements can be used not only to diagnose osteoporosis at the hip, but also to give prognostic information on the lifetime risk of hip fracture. A number of additional risk factors enhance the ability of density measurements to assess risk. Candidates include markers of bone resorption, prior fragility fractures, hip axis length, and estimates of postural integrity, each of which improve prognostic value independently of bone mineral assessments. Their use in the stratification of risk will help define intervention thresholds for treatments and improve the design of population screening policies, particularly in elderly women in whom the burden of hip fracture is greatest.

  9. Hip Resurfacing Arthroplasty and Perioperative Blood Testing

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available It is standard practice in many institutions to routinely perform preoperative and postoperative haemoglobin level testing in association with hip joint arthroplasty procedures. It is our observation, however, that blood transfusion after uncomplicated primary hip arthroplasty in healthy patients is uncommon and that the decision to proceed with blood transfusion is typically made on clinical grounds. We therefore question the necessity and clinical value of routine perioperative blood testing about the time of hip resurfacing arthroplasty. We present analysis of perioperative blood tests and transfusion rates in 107 patients undertaking unilateral hybrid hip resurfacing arthroplasty by the senior author at a single institution over a three-year period. We conclude that routine perioperative testing of haemoglobin levels for hip resurfacing arthroplasty procedures does not assist in clinical management. We recommend that postoperative blood testing only be considered should the patient demonstrate clinical signs of symptomatic anaemia or if particular clinical circumstances necessitate.

    SUMMARY: The aim of this study was to estimate the incidence of hip fracture in Kermanshah, Iran. 161 cases (88 men and 73 women) were recorded. The annual age-standardized incidence rates were 181.1/100,000 in men and 214.6/100,000 in women. Incidence rate of hip fracture was less than in Western countries. INTRODUCTION: Hip fracture is the most serious complication of osteoporosis, the most common metabolic bone disease worldwide. The incidence of hip fracture in the elderly patients varies in different areas. The aim of this study was to estimate the incidence rate of hip fracture in Kermanshah, Iran. MATERIALS AND METHODS: All cases of hip fracture patients who aged 50 years or more admitted in six referral orthopedic hospitals in Kermanshah from May 21, 2007 to May 21, 2008 were studied. The age- and sex-specific incidence rates of hip fracture per 100,000 persons were calculated using the population data from the last national census in Iran, 2007. RESULTS: A total of 161 cases of hip fracture (88 men and 73 women) were recorded. The annual age-standardized incidence rates were 181.1/100,000 in men and 214.6/100,000 in women. The female to male ratio of hip fracture incidence was 1.18. CONCLUSION: We found a relatively low incidence of hip fracture in Iran than in Western countries, which is mostly due to the lower rate in women. This is probably related to the different lifestyle factors in different societies.

    OBJECTIVE: Decreased hip muscle strength is frequently reported in patients with hip injury or pathology. Furthermore, soccer players suffering from groin injury show decreased strength of hip muscles. Estimating 10-repetition maximum can be time-consuming and difficult, thus, using the Borg...... category rating 10 scale (Borg CR10 scale) can be a useful tool for estimating the intensity of exercise. The aims of this study were 1) to investigate the feasibility of the use of the Borg CR10 scale for rating strength training intensity of the hip abductor and hip adductor muscles, and 2) to compare...... hip muscle activity during hip abduction and hip adduction exercises using elastic resistance and isotonic machines, using electromyography (EMG). METHODS: EMG activity was recorded from 11 muscles at the hip, thigh and trunk during hip adduction and hip abduction exercises in 16 untrained women...

    1983-10-01

    We analyzed the preoperative and perioperative data on sixty-nine consecutive complex total hip replacements performed in fifty-seven patients using miniature or microminiature custom-made femoral components. The patients' average age was 45.7 years. The preoperative diagnosis was congenital dysplasia or dislocation of the hip in 72 per cent of the hips. Acetabular bone grafts were required in thirty-seven of the sixty-nine hips. Operative complications occurred in thirteen (19 per cent) and postoperative dislocation occurred in eleven (16 per cent) of the sixty-nine hips. Fifty-five hips in forty-seven patients were followed for a minimum of two years, the average follow-up being 4.8 years and the longest, 9.8 years. All acetabular grafts united. Loosening of one or both prosthetic components occurred in ten (18 per cent) of the fifty-five hips (twelve of the 110 components became loose). There were no instances of a stem bending or fracturing, despite the small size of the femoral components. Eight hips (14.5 per cent) had undergone revision, six for painful loose components and two for recurrent dislocation. For the forty-seven hips that were not revised, the average Harris hip score rose from 43 points preoperatively to 80 points postoperatively.

    The purpose of this case-control study was to characterise hip joint kinematics and moments during gait in people with mild-to-moderate hip osteoarthritis (OA). Eligible participants were allocated to the hip OA group (n=27) or the age-matched control group (n=26) based on radiographic and symptomatically defined inclusion criteria. Participants walked barefoot along a 10-m walkway at their self-selected gait speed. Trajectories of 43 markers attached to the trunk, pelvis, upper and lower limbs were recorded using a 12-camera motion capture system. Ground reaction force data were simultaneously collected. Individuals in the hip OA group had a 10% higher body mass, 13% slower self-selected walking speed, 10% shorter step length, 2% and 9% longer relative stance and double support duration (% stride) respectively, 41% lower sagittal plane hip range of motion, and 28% and 45% lower peak sagittal and transverse plane hip joint moments respectively during gait compared to controls (phip OA experienced less net hip joint loading over a reduced range of hip motion for a longer proportion of the gait cycle when walking at their preferred gait speed suggest that the mechanics of the hip joint are altered in hip OA, and could have implications for disease progression through altered mechano-biological processes within the joint.

    2014-09-01

    Full Text Available Developmental dysplasia of the hip (DDH or congenital hip dysplasia (CDH is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DDH, 32.5 years for low dislocation, 31.2 years for high dislocation with a false acetabulum, and 46.4 years for high dislocation without a false acetabulum. Thorough understanding of the bony and soft tissue deformities induced by dysplasia is crucial for the success of total hip arthroplasty. It is important to evaluate the existing acetabular deformity three-dimensionally, and customize the correction in accordance with the quantity and location of ace tabular deficiencies. Acetabular reconstruction in patients with DDH is hallenging. Interpretation of published data is difficult and should be done with caution because most series include patients with different types of hip disease. In general, the complication rate associated with THA is higher in patients with hip dysplasia than it is in patients with osteoarthritis. Overall, clinical and functional outcomes following THA in patients hip dysplasia (DDH differ from those treated for primary hip osteoarthritis, possibly due to the lower age and level of activity. Although function scores decline with age, the scores for pain and range of motion presented with a statistically significant improvement in the long-term.

    To evaluate factors associated with lameness severity and hip joint range of motion in dogs with hip dysplasia and to assess the association between hip joint range of motion and degree of lameness. Prospective case series. 60 client-owned Labrador Retrievers with hip dysplasia. Owners completed a questionnaire regarding their dogs' daily exercise duration and type (i.e., low impact vs high impact) and lifestyle. Range of motion of affected hip joints was measured with a transparent plastic goniometer. The presence of subluxation or luxation of hip joints as a consequence of hip dysplasia and the size of the largest osteophytes or enthesophytes of hip joints on ventrodorsal radiographic images of the pelvis were recorded. Multivariate analyses were performed to identify factors associated with lameness, loss of hip joint flexion, and loss of hip joint extension and to identify factors associated with the presence of large osteophytes. Exercise was associated with a decrease in the severity of lameness in dogs with hip dysplasia. The strength of this inverse relationship increased with longer exercise duration. Lameness was more severe in dogs with hip joint luxation than in dogs without luxation. Hip joint extension was 1° lower for each year of age, and osteophyte or enthesophyte size was 1 mm larger with each 3-year increase in age. Longer daily exercise duration was associated with lower lameness scores in dogs with hip dysplasia. Dogs with hip joint luxation secondary to hip dysplasia had higher lameness scores than did dogs without hip joint luxation.

    2013-01-01

    Full Text Available Pathological changes that develop in the hip joints (HJ have different origins and mechanisms of development, but their main manifestation is pain. The nature of this pain cannot be well established on frequent occasions. The English-language medical literature currently classifies such disorders as greater trochanter pain syndrome (GTPS. Its major signs are chronic pain and local palpatory tenderness in the outer part of HJ. The development of GTPS may be associated with inflammation of the synovial bursae situated in the greater tronchanter, as well as with tendinitis, myorrhexis, iliotibial band syndrome, and other local changes in the adjacent tissues or with systemic diseases. So GTPS may be characterized as regional pain syndrome that frequently mimics pain induced by different diseases, including myofascial pain syndrome, osteoarthrosis, spinal diseases, etc.

    Objective Using biomechanical studies, this research aims to compare hip capsulorrhaphy in rabbits, carried out with two different techniques: capsulorrhaphy with simple sutures and with anchors. Method Thirteen New Zealand Albino (Oryctolaguscuniculus) male rabbits, twenty-six hip joints, were used. First, a pilot project was performed with three rabbits (six hip joints). This experiment consisted of ten rabbits divided into two groups: group 1 underwent capsulorrhaphy on both right and left hips with simple suture using polyglycolic acid absorbable thread, and group 2 underwent capsulorrhaphy with titanium anchors. After a four-week postoperative period, the animals were euthanized and the hip joints were frozen. On the same day of the biomechanical studies, after the hip joints were previously unfrozen, the following parameters were evaluated: rigidity, maximum force, maximum deformity and energy. Results There was no relevant statistical difference in rigidity, maximum force, maximum deformity and energy between the simple suture and anchor groups. Conclusion Through biomechanical analyses, using parameters of rigidity, maximum force, maximum deformity and energy, it has been shown that capsulorrhaphy with simple suture and with anchors has similar results in rabbit hip joints.

    Full Text Available Hip fractures often result in serious health implications, particularly in the geriatric population, and have been related to long-term morbidity and death. In most cases, these fractures are caused by impact loads in the area of the greater trochanter, which are produced in a fall. This work is aimed at developing hip protectors using composite materials and evaluating their effectiveness in preventing hip fractures under high impact energy (120 J. The hip protectors were developed with an inner layer of energy absorbing soft material and an outer rigid shell of fiberglass-reinforced polymer composite. According to the experimental results, all tested configurations proved to be effective at reducing the impact load to below the average fracture threshold of proximal femur. Furthermore, an addition of Ethylene Vinyl Acetate (EVA to the impacted area of the composite shell proved to be beneficial to increase impact strength of the hip protectors. Thus, composite hip protectors proved to be a viable alternative for a mechanically efficient and cost-effective solution to prevent hip fractures.

    Hip dislocation is a major and common complication of total hip arthroplasty (THA), which appears with an incidence between 0.3% and 10% in primary total hip arthroplasties and up to 28% in revision THA. The hip dislocations can be classified into three groups: early, intermediate and late. Approximately two-thirds of cases can be treated successfully with a non-operative approach. The rest require further surgical intervention. The prerequisite to developing an appropriate treatment strategy is a thorough evaluation to identify the causes of the dislocation. In addition, many factors that contribute to THA dislocation are related to the surgical technique, mainly including component orientation, femoral head diameter, restoration of femoral offset and leg length, cam impingement and condition of the soft tissues. The diagnosis of a dislocated hip is relatively easy because the clinical situation is very typical. Having identified a dislocated hip, the first step is to perform a closed reduction of the implant. After reduction you must perform a computed tomography scan to evaluate the surgical options for treatment of recurrent dislocation that include: revision arthroplasty, modular components exchange, dual-mobility cups, large femoral heads, constrained cups, elimination of impingement and soft tissue procedures. The objective is to avoid further dislocation, a devastating event which is increasing the number of operations on the hip. To obtain this goal is useful to follow an algorithm of treatment, but the best treatment remains prevention.

    To evaluate the risk factors after total hip replacement arthroplasty for rerevision and to analyze complications after hip revision surgery. We obtained data from 117 hip revisions and 12 hip rerevision arthroplasties performed in 1992-2001 in the Department of Orthopedics of Klaipeda Hospital. Special forms were filled in for every patient who participated in the study. Name, operation date, type of implants, operative technique, revision diagnosis, intraoperative and postoperative complications were recorded. All patients were checked for death until 2003. Hip revisions were performed for 77 (66%) women and 50 (44%) men in 1992-2001. We revised 22 (19%) cups, 6 (5%) stems, 86 (74%) total hip revisions; femoral head was exchanged for 3 patients. Revision diagnoses were: aseptic loosening in 106 (90%) cases, recurrent dislocations in 7 (6%) cases, and periprosthetic fractures in 4 (4%) cases. Patients' age varied from 26-82 years, average 63.5 years. In revision group only 8% of patients were less than 50 years old, compared to 33% in rerevision group. Morselized allografts and bone impaction technique for reconstruction of bone defects were used in 70 (60%) of cases. We rerevised one cup only for which revision morselized allografts were used. Eight (67%) rerevisions were performed after first 28 (24%) hip revisions. Patients, who underwent revision surgery being younger than 50 years old, were at higher risk for rerevision surgery. Revision with morselized bone allografts and bone impaction technique decreases number of rerevisions. Learning curve was steep and had great influence to our results.

    The aim of the Danish Hip Arthroplasty Register (DHR) is to continuously monitor and improve the quality of treatment of primary and revision total hip arthroplasty (THA) in Denmark. The DHR is a Danish nationwide arthroplasty register established in January 1995. All Danish orthopedic departments - both public and private - report to the register, and registration is compulsory. The main variables in the register include civil registration number, indication for primary and revision surgery, operation date and side, and postoperative complications. Completeness of primary and revision surgery is evaluated annually and validation of a number of variables has been carried out. A total of 139,525 primary THAs and 22,118 revisions have been registered in the DHR between January 1, 1995 and December 31, 2014. Since 1995, completeness of procedure registration has been high, being 97.8% and 92.0% in 2014 for primary THAs and revisions, respectively. Several risk factors, such as comorbidity, age, specific primary diagnosis and fixation types for failure of primary THAs, and postoperative complications, have been identified through the DHR. Approximately 9,000 primary THAs and 1,500 revisions are reported to the register annually. The DHR is important for monitoring and improvement of treatment with THA and is a valuable tool for research in THA surgery due to the high quality of prospective collected data with long-term follow-up and high completeness. The register can be used for population-based epidemiology studies of THA surgery and can be linked to a range of other national databases.

    Canine hip dysplasia (CHD) is a complex, polygenic disease radiographically associated with hip subluxation and development of osteoarthritis. Screening programs have been established with the goal of hip improvement, with the most common in the United States being OFA hip scoring and the PennHIP method. When evaluating the single hip-extended view used by OFA versus the 3 radiographic views and associated distraction index (DI) used by PennHIP for CHD screening, the scientific evidence supports the use of the DI and PennHIP method. OFA scoring can be used to effect hip improvement, especially when incorporated into estimated breeding values. Copyright © 2017 Elsevier Inc. All rights reserved.

    2011-01-01

    The external snapping hip syndrome is a condition characterized by palpable or audible snap on the lateral region of the hip occurring during movements and sometimes associated with pain. It is typical of young adults and athletes and can be favored by the abnormal sliding of the iliotibial band or of the gluteus maximus muscle over the greater trochanter. We present a case of external snapping hip syndrome occurring in a young woman secondary to a dysmorphic sickle-shaped myotendinous junction of the gluteus maximus muscle. Diagnosis was allowed by an integrated clinical and radiological approach, based on dynamic ultrasound and magnetic resonance imaging (MRI).

    PURPOSE: To compare the quantity of bone removed from the acetabulum during resurfacing hip arthroplasty versus uncemented total hip arthroplasty (THA). METHODS: 62 consecutive patients with osteoarthritis of the hip were prospectively studied. 24 men and 7 women aged 40 to 86 (mean, 59) years underwent Birmingham hip resurfacing. 13 men and 18 women aged 34 to 88 (mean, 61) years underwent uncemented THA using the trident acetabular cup. Obese elderly women at risk of femoral neck fracture and patients with large subchondral pseudocysts or a history of avascular necrosis of the femoral head were assigned to uncemented THA. Acetabular reamings were collected; marginal osteophytes were not included. The reamings were dehydrated, defatted, and weighed. RESULTS: The mean weight of acetabular reamings was not significantly different between patients undergoing hip resurfacing and uncemented THA (p=0.57). CONCLUSION: In hip resurfacing, the use of an appropriately small femoral component avoids oversizing the acetabular component and removal of excessive bone stock.

    2010-01-01

    Analysis of diverse signaling systems has revealed that one important level of control is regulation of membrane trafficking of ligands and receptors. The activities of some ligands are also regulated by whether they are membrane bound or secreted. In Drosophila, several morphogenetic signals that play critical roles in development have been found to be subject to such regulation. For example, activity of the Hedgehog (Hh) is regulated by Raspberry, which palmitoylates Hh. Similarly, the palmitoylases Porcupine and Raspberry increase the activities of Wingless (Wg) and the EGF-ligand Spitz (Spi) respectively. In contrast to its vertebrate homologues, which have typical N-terminal signal sequences, the precursor form of Drosophila Hh contains an internal type-II secretory signal motif. The Short Gastrulation (Sog) protein is another secreted Drosophila protein that contains a type-II signal and differs from its vertebrate ortholog Chordin which contains a standard signal peptide. In this study, we examine the regulation of Sog secretion and regulation by dHIP14, the ortholog of a mammalian palmitoylase first identified as Huntington Interacting Protein (HIP). We show that dHIP14 binds to Sog and that Sog is palmitoylated. In S2 cells, dHIP14 promotes secretion of Sog as well as stabilizing a membrane associated form of Sog. We examined the requirement for candidate Cysteine residues in the N-terminal predicted cytoplasmic domain of Sog and find that Cys27, one of two adjacent Cysteines (Cys27,28), is essential for the full activity of dHIP14 and its effect on Sog. Finally, we find that dHIP14 promotes the activity of Sog in vivo. These studies highlight the growing importance of lipid modification in regulating signaling at the level of ligand production and localization. PMID:20599894

    Full Text Available Introduction: Snapping hip syndrome (SHS occurs in 5-10% of the global population. A back and forth skip of the tendon of the dysfunctional muscle across the osseous prominence is the most common symptom of this condition. Mainly young generation suffers from SHS. Depending on the structures that cause an audible snap, snapping hip syndrome may be classified into intra-articular and extra-articular types. The main aim of the research was to assess the strength of the major hip muscles and static balance in patients with snapping hip syndrome.

  14. Mild to Moderate Hip OA: Joint Preservation or Total Hip Arthroplasty?

    2015-07-01

    Treatment of structural hip disease such as FAI and acetabular dysplasia has increased dramatically over the past decade with the goal of preservation of the native hip joint. A number of patient and disease specific parameters including the amount of underlying hip osteoarthrosis can help predict success with joint preservation surgery. Total hip arthroplasty remains a very good option in young patients who are not ideal candidates for joint preservation surgery. Future developments will help to better identify ideal surgical candidates and improve understanding of the disease processes. Copyright © 2015 Elsevier Inc. All rights reserved.

  15. Interventions for hip pain in the maturing athlete: the role of hip arthroscopy?

    Science.gov (United States)

    Gomberawalla, M Mustafa; Kelly, Bryan T; Bedi, Asheesh

    2014-01-01

    Femoroacetabular impingement (FAI) alters hip mechanics, results in hip pain, and may lead to secondary osteoarthritis (OA) in the maturing athlete. Hip impingement can be caused by osseous abnormalities in the proximal femur or acetabulum. These impingement lesions may cause altered loads within the hip joint, which result in repetitive collision damage or sheer forces to the chondral surfaces and acetabular labrum. These anatomic lesions and resultant abnormal mechanics may lead to early osteoarthritic changes. Relevant articles from the years 1995 to 2013 were identified using MEDLINE, EMBASE, and the bibliographies of reviewed publications. Level 4. Improvements in hip arthroscopy have allowed FAI to be addressed utilizing the arthroscope. Adequately resecting the underlying osseous abnormalities is essential to improving hip symptomatology and preventing further chondral damage. Additionally, preserving the labrum by repairing the damaged tissue and restoring the suction seal may theoretically help normalize hip mechanics and prevent further arthritic changes. The outcomes of joint-preserving treatment options may be varied in the maturing athlete due to the degree of underlying OA. Irreversible damage to the hip joint may have already occurred in patients with moderate to advanced OA. In the presence of preexisting arthritis, these patients may only experience fair or even poor results after hip arthroscopy, with early conversion to hip replacement. For patients with advanced hip arthritis, total hip arthroplasty remains a treatment option to reliably improve symptoms with good to excellent outcomes and return to low-impact activities. Advances in the knowledge base and treatment techniques of intra-articular hip pain have allowed surgeons to address this complex clinical problem with promising outcomes. Traditionally, open surgical dislocations for hip preservation surgery have shown good long-term results. Improvements in hip arthroscopy have led to

  1. Computed tomography through the hip joint

    1981-09-01

    Computed tomography through the hip joint should be used only after conventional radiographs (at least a.p. views). It may provide information that is diagnostic or helpful, e.g. in bacterial infections, trauma of praearthrotic states. Indications for surgery may be obtained in the presence of inflammatory-rheumatic and degenerative hip disease, arthritic deformities and trauma, and the type of suitable operation may be indicated. The obturator internus muscle, which can be seen medial to the acetabulum on the scan, is an important diagnostic indicator where there is trauma or bacterial infection of the hip joint. The capsule of the hip joint can be visualized directly. Slice thickness of 6 mm, or less is necessary.

  2. Atraumatic Anterior Dislocation of the Hip Joint

    2015-01-01

    Full Text Available Dislocation of the hip joint in adults is usually caused by high-energy trauma such as road traffic accidents or falls from heights. Posterior dislocation is observed in most cases. However, atraumatic anterior dislocation of the hip joint is extremely rare. We present a case of atraumatic anterior dislocation of the hip joint that was induced by an activity of daily living. The possible causes of this dislocation were anterior capsule insufficiency due to developmental dysplasia of the hip, posterior pelvic tilt following thoracolumbar kyphosis due to vertebral fracture, and acetabular anterior coverage changes by postural factor. Acetabular anterior coverage changes in the sagittal plane were measured using a tomosynthesis imaging system. This system was useful for elucidation of the dislocation mechanism in the present case.

  3. Structure and interactions of a dimeric variant of sHIP, a novel virulence determinant of Streptococcus pyogenes

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available Streptococcus pyogenes is one of the most significant bacterial pathogens in the human population mostly causing superficial and uncomplicated infections (pharyngitis and impetigo but also invasive and life-threatening disease. We have previously identified a virulence determinant, protein sHIP, which is secreted at higher levels by an invasive compared to a non-invasive strain of S. pyogenes. The present work presents a further characterization of the structural and functional properties of this bacterial protein. Biophysical and structural studies have shown that protein sHIP forms stable tetramers both in the crystal and in solution. The tetramers are composed of four helix-loop-helix motifs with the loop regions connecting the helices displaying a high degree of flexibility. Owing to interactions at the tetramer interface, the observed tetramer can be described as a dimer of dimers. We identified three residues at the tetramer interface (Leu84, Leu88, Tyr95, which due to largely non-polar side-chains, could be important determinants for protein oligomerization. Based on these observations, we produced a sHIP variant in which these residues were mutated to alanines. Biophysical experiments clearly indicated that the sHIP mutant appear only as dimers in solution confirming the importance of the interfacial residues for protein oligomerisation. Furthermore, we could show that the sHIP mutant interacts with intact histidine-rich glycoprotein (HRG and the histidine-rich repeats in HRG, and inhibits their antibacterial activity to the same or even higher extent as compared to the wild type protein sHIP. We determined the crystal structure of the sHIP mutant, which, as a result of the high quality of the data, allowed us to improve the existing structural model of the protein. Finally, by employing NMR spectroscopy in solution, we generated a model for the complex between the sHIP mutant and an HRG-derived heparin-binding peptide, providing further

  4. Epidemiology of hip fracture: Worldwide geographic variation

    Directory of Open Access Journals (Sweden)

    Dinesh K Dhanwal

    2011-01-01

    Full Text Available Osteoporosis is a major health problem, especially in elderly populations, and is associated with fragility fractures at the hip, spine, and wrist. Hip fracture contributes to both morbidity and mortality in the elderly. The demographics of world populations are set to change, with more elderly living in developing countries, and it has been estimated that by 2050 half of hip fractures will occur in Asia. This review conducted using the PubMed database describes the incidence of hip fracture in different regions of the world and discusses the possible causes of this wide geographic variation. The analysis of data from different studies show a wide geographic variation across the world, with higher hip fracture incidence reported from industrialized countries as compared to developing countries. The highest hip fracture rates are seen in North Europe and the US and lowest in Latin America and Africa. Asian countries such as Kuwait, Iran, China, and Hong Kong show intermediate hip fracture rates. There is also a north-south gradient seen in European studies, and more fractures are seen in the north of the US than in the south. The factors responsible of this variation are population demographics (with more elderly living in countries with higher incidence rates and the influence of ethnicity, latitude, and environmental factors. The understanding of this changing geographic variation will help policy makers to develop strategies to reduce the burden of hip fractures in developing countries such as India, which will face the brunt of this problem over the coming decades.

    We describe a case of external snapping hip diagnosed by dynamic sonography. The case prompted us to retrospectively review the imaging findings of children who clinically had presented with snapping hip. From this review we identified the features on MRI and CT of either thickening of the iliotibial band or thickening of the anterior edge of the gluteus maximus muscle as the cause of snapping and atrophy of the bulk of gluteus maximus muscle as an important secondary sign associated with snapping.

    Hemiarthroplasty of the hip is a commonly performed procedure for subcapital neck of femur fractures. Dislocation of the hemiarthroplasty is a recognised but uncommon complication. Dislocations can be complicated by the uncoupling or dissociation of the femoral head component from the femoral stem. Dissociations are rare and require open reduction. We present a case of a patient with a hip hemiarthroplasty dislocation and dissociation subsequent to a fall. 2015 BMJ Publishing Group Ltd.

    The dislocated hip in a non-ambulatory child with spastic paresis tends to be a painful interference to sleep, sitting upright, and perineal care. Proximal femoral resection-interposition arthroplasty is one method of treatment for this condition. We reviewed eight hips, two bilateral cases, with a mean follow-up of 30 months. Clinical improvement was observed in all except one case, with respect to pain relief and sitting tolerance. Some proximal migration was observed in three cases, despit...

    We examined whether blood levels of two markers of fibrosis (transforming growth factor beta one (TGF-β1) and procollagen type III N-terminal propeptide (PIIINP)) are related to hip fracture risk and to bone mineral density (BMD). TGF-β1 levels were associated with lower hip fracture risk in women and with lower BMD in men. PIIINP levels were not associated with either outcome. TGF-β1 serves several roles in bone formation and resorption. A consequence of TGF-β1 activation is the production of PIIINP, a marker of collagen III deposition. Here, we explore whether these two biomarkers are related to incident hip fracture and bone mineral density (BMD) and whether their associations are modified by systemic inflammation, as measured by C-reactive protein (CRP) levels. Participants were from the Cardiovascular Health Study (mean age 78 years; mean follow-up 8.3 years). We included 1681 persons with measured levels of TGF-β1 (149 hip fractures) and 3226 persons with measured levels of PIIINP (310 hip fractures). Among women, higher TGF-β1 levels were associated with lower hip fracture risk (HR, per doubling, 0.78 [95 % CI 0.61, 0.91]). Among men, TGF-β1 levels were associated with hip fracture risk in a non-linear manner, but among those with elevated CRP levels, doubling was associated with increased risk of fracture (HR 2.22 [1.20, 4.08]) (p = 0.02, interaction between low and high CRP and TGF-β1 on fracture risk). TGF-β1 levels had no significant association with total hip or total body BMD in women but were significantly associated with lower BMD in men. There were no associations of PIIINP levels with hip fracture risk or BMD in men or women. TGF-β1 levels appear to be associated with bone-related phenotypes in a sex-specific manner. The reasons for these differences between men and women regarding TGF-β1 levels and hip fracture risk and bone density require further investigation.

  10. Tuberculosis of hip: A current concept review

    Saraf, Shyam Kumar; Tuli, Surendra Mohan

    2015-01-01

    Tuberculosis (TB) of the hip is second to spine only hence a good number of cases are visiting the medical facilities every year. Many present in the advanced stage of the disease due to delayed diagnosis. In early stages of TB of hip, there is a diagnostic dilemma when plain X-rays are negative. In the present time, diagnostic modalities have improved from the days when diagnosis was based essentially on clinicoradiological presentation alone. By the time definite radiological changes appear on plain X-ray, the disease has moderately advanced. The modern diagnostic facilities like ultrasonography (USG) or magnetic resonance imaging of the hip joint, USG guided aspiration of synovial fluid and obtaining the material for polymerase chain reaction and tissue diagnosis must be utilized. In the treatment, current emphasis is more on mobility with stability at hip. Joint debridement, skeletal traction, and mobilization exercises may give more satisfying results as compared to the immobilization by hip spica. Adults with advanced arthritis and healed infection should be informed and discussed the various treatment modalities including the joint replacement. More and more surgeons are taking up the challenge of putting the total hip replacement in the active stage of the disease. Until the long term results in active disease are well established, we recommend it for the healed disease only in selected cases. PMID:25593352

    To detail our early experience using concomitant hip arthroscopy and periacetabular osteotomy (PAO) for the treatment of acetabular dysplasia. We prospectively collected and retrospectively reviewed the surgical and outcome data of 17 patients who underwent concomitant hip arthroscopy and PAO between October 2010 and July 2013. Preoperative and postoperative range of motion, outcome and pain scores, and radiographic data were collected. Intraoperative arthroscopic findings and postoperative complications were recorded. The group consisted of 3 male and 14 female patients with a mean follow-up period of 2.4 years. Three patients had undergone previous surgery on the affected hip. Chondrolabral pathology was identified in all 17 patients. Twelve patients underwent labral repair, and five patients underwent partial labral debridement. No patient was converted to total hip arthroplasty or required revision surgery at short-term follow-up. All 4 patient-reported outcome scores showed statistically significant changes from baseline to latest follow-up (P hip arthroscopy and PAO has been favorable. We noted that all our patients have evidence of chondrolabral damage at the time of PAO when the joint is distracted and evaluated. All patients in this series had intra-articular pathology treated arthroscopically and showed satisfactory mean clinical improvement. Hip arthroscopy with PAO did not appear to introduce complications beyond the PAO alone. Level IV, therapeutic case series. Copyright © 2015 Arthroscopy Association of North America.

    Full Text Available Tuberculosis (TB of the hip is second to spine only hence a good number of cases are visiting the medical facilities every year. Many present in the advanced stage of the disease due to delayed diagnosis. In early stages of TB of hip, there is a diagnostic dilemma when plain X-rays are negative. In the present time, diagnostic modalities have improved from the days when diagnosis was based essentially on clinicoradiological presentation alone. By the time definite radiological changes appear on plain X-ray, the disease has moderately advanced. The modern diagnostic facilities like ultrasonography (USG or magnetic resonance imaging of the hip joint, USG guided aspiration of synovial fluid and obtaining the material for polymerase chain reaction and tissue diagnosis must be utilized. In the treatment, current emphasis is more on mobility with stability at hip. Joint debridement, skeletal traction, and mobilization exercises may give more satisfying results as compared to the immobilization by hip spica. Adults with advanced arthritis and healed infection should be informed and discussed the various treatment modalities including the joint replacement. More and more surgeons are taking up the challenge of putting the total hip replacement in the active stage of the disease. Until the long term results in active disease are well established, we recommend it for the healed disease only in selected cases.

    Female, 30. Intertrochanteric fracture under an arthrodesed hip. Developmental dysplasia of the hip. Pain • inability to walk. Open reduction and internal fixation. Orthopedics and traumatology. Rare disease, Unusual setting of medical care. An intertrochanteric fracture among elderly people is common, but it is rare to see such a fracture under a longstanding hip arthrodesis. Its surgical management represents a real challenge to orthopedic surgeons. A 30-year-old female teacher with long-standing hip arthrodesis was involved in a traffic accident. Clinical and radiological examination revealed the presence of a displaced intertrochanteric fracture under an arthrodesed hip and high neck shaft angle. Before embarking on surgery, we have to consider many factors such as patient personality (a young active and ambitious woman) and the mature of the fracture (a displaced fracture, coxa valga, and atrophied muscles). After a deep discussion and evaluation of the available devices, we selected a heavy duty locked plate and cannulated screws to fix the fracture. Because of the rarity of intertrochanteric fracture under an arthrodesis hip, the proper surgical treatment is controversial. Nevertheless, we were fortunate in successfully treating this unusual fracture using a locked plate and cannulated screws, which are implants that can be useful in treatment of such fractures.

    To assess the radiographic features of 36 hips with hereditary multiple exostoses (HME). Hip parameters of 12 males and 6 females (36 hips) aged 2 to 28 years with HME were assessed using anteroposterior radiographs. The recorded features included the sites of osteochondromas, the femoral head/neck ratio, the Reimer's migration percentage, Sharp's acetabular angle, the centre edge angle, the femoral neck-shaft angle, and degenerative changes. 15 of the 18 patients were asymptomatic; 3 complained of pain (2 underwent excision or bone biopsy); no lesion was malignant. Osteochondromas were most commonly located in the femur followed by the ilium; only one was intra-articular. 32 hips had coxa valga; 26 had an abnormal Reimer's migration percentage; 17 had an abnormal Sharp's acetabular angle; 12 had an abnormal centre edge angle; 32 had an abnormal femoral neck-shaft angle; and 6 had degenerative changes. Acetabular and femoral dysplasia as well as subluxation are common in patients with HME. Borderline subluxated hips and those with marked coxa valga and/or acetabular dysplasia should be closely monitored to determine the need for surgery in the future. Subluxated hips should be operated on early, particularly in children and symptomatic adults.

    Osteocalcin (OC) is the most abundant non-collagenous bone protein and is determinant for bone mineralization. We aimed to compare OC bone expression and serum factors related to its carboxylation in hip fragility fracture and osteoarthritis patients. We also aimed to identify which of these factors were associated with worse mechanical behavior and with the hip fracture event. In this case-control study, fragility fracture patients submitted to hip replacement surgery were evaluated and compared to a group of osteoarthritis patients submitted to the same procedure. Fasting blood samples were collected to assess apolipoproteinE (apoE) levels, total OC and undercarboxylated osteocalcin (ucOC), vitamin K, LDL cholesterol, triglycerides and bone turnover markers. The frequency of the apoε4 isoform was determined. Femoral epiphyses were collected and trabecular bone cylinders drilled in order to perform compression mechanical tests. Gene expression of bone matrix components was assessed by quantitative RT-PCR analysis. 64 patients, 25 submitted to hip replacement surgery due to fragility fracture and 39 due to osteoarthritis, were evaluated. Bone OC/collagen expression (OC/COL1A1) ratio was significantly lower in hip fracture compared to osteoarthritis patients (phip fracture event (OR ~0; p=0.003) independently of the group assigned, or the clinical characteristics. Apoε4 isoform was more frequent in the hip fracture group (p=0.029). ucOC levels were higher in the fracture group although not significantly (p=0.058). No differences were found regarding total OC (p=0.602), apoE (p=0.467) and Vitamin K (p=0.371). In hip fracture patients, multivariate analysis, adjusted for clinical characteristics, serum factors related to OC metabolism and gene expression of bone matrix proteins showed that low OC/COL1A1 expression ratio was significantly associated with worse trabecular strength (β=0.607; p=0.013) and stiffness (β=0.693; p=0.003). No association was found between

    Contra-lateral hip fractures in elderly patients with a previous hip fracture increase the incidence of complications and socioeconomic burden. The purpose of this study was to identify the risk factors that contribute to the occurrence of contra-lateral hip fracture in elderly patients. Among 1093 patients treated for a hip fracture, 47 patients sustained a contra-lateral hip fracture. These patients were compared with 141 patients with a unilateral hip fracture (controls). The incidence of contra-lateral hip fracture was 4.3% among the 1093 patients treated for a hip fracture at our institute. A contra-lateral hip fracture occurred within 2 years of initial fracture in 66%, and subsequently, the annual incidence rate decreased. A similar fracture pattern was noted in 70% of patients who sustained an intertrochanteric fracture. In terms of preoperative factors, respiratory disease (OR 2.57, P=0.032) and visual impairment (OR 2.51, P=0.012) were higher in patients with a contra-lateral hip fracture than in controls, and for postoperative factors, the proportions of patients with postoperative delirium (OR 2.91, P=0.022), late onset of rehabilitation (OR 1.05, P=0.023), and poor ambulatory status at 3 months (OR 1.34, P=0.002) were also significantly higher in patients than in controls. Postoperative delirium and underlying visual impairment and respiratory disease could be risk factors of contra-lateral fracture in elderly patients. Early and active rehabilitation after surgery is important to prevent the occurrence of contra-lateral hip fracture in the elderly. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Objective Hip pain and injury as a result of activity can lead to the development of early hip osteoarthritis (OA) in susceptible individuals. Our understanding of the factors that increase susceptibility continues to evolve. The ability to clearly identify individuals (and cohorts) with activity-related hip pain who are at risk of early hip OA is currently lacking. The purpose of this study was to gain expert consensus on which key clinical measures might help predict the risk of early hip OA in individuals presenting with activity-related hip pain. The agreed measures would constitute a standardised approach to initial clinical assessment to help identify these individuals. Methods This Dephi study used online surveys to gain concordance of expert opinion in a structured process of ‘rounds’. In this study, we asked ‘What outcome measures are useful in predicting hip OA in activity-related hip pain?’ The Delphi panel consisted of experts from sport and exercise medicine, orthopaedics, rheumatology, physiotherapy and OA research. Results The study identified key clinical measures in the history, examination and investigations (plain anteroposterior radiograph and femoroacetabular impingement views) that the panel agreed would be useful in predicting future risk of hip OA when assessing activity-related hip pain. The panel also agreed that certain investigations and tests (eg, MR angiography) did not currently have a role in routine assessment. There was a lack of consensus regarding the role of MRI, patient-reported outcome measures (PROMs) and certain biomechanical and functional assessments. Conclusions We provide a standardised approach to the clinical assessment of patients with activity-related hip pain. Assessment measures rejected by the Delphi panel were newer, more expensive investigations that currently lack evidence. Assessment measures that did not reach consensus include MRI and PROMs. Their role remains ambiguous and would benefit from further

    Tuberculosis remains a major public health problem in developing countries. Diagnosing extrapulmonary tuberculosis can be difficult, as it requires a higher index of suspicion than primary tuberculosis. Extrapulmonary tuberculosis may mimic malignancies and many other diseases, so it should be included in the differential diagnosis. Here, we present a case of extrapulmonary tuberculosis associated with Pott's disease and hip arthritis in a patient who recovered after 12 months of antituberculosis therapy. A 16-year-old girl presented to the outpatient otolaryngology clinic with painless swelling of the neck, and to the physical medicine and rehabilitation clinic with complaints of hip and low back pain that mimicked spondyloarthropathy. She was eventually referred to the outpatient pediatric clinic. Her acute-phase reactants were high, and hilar lymphadenopathy was evident on chest x-ray. On computerized tomography, a Pott's abscess involving the T8, T9, and T10 vertebrae was suspected. Magnetic resonance imaging of the dorsal vertebrae and hip was performed, and a Pott's abscess and hip tuberculous arthritis were confirmed. The patient had been exposed to tuberculosis 10 years earlier, and her purified protein derivative (PPD) test was 16 mm. After antituberculosis treatment, our patient recovered and the Pott's disease and hip tuberculous arthritis regressed. Extrapulmonary tuberculosis may mimic many other diseases, so it should be kept in mind in the differential diagnosis. It is essential to diagnose osteoarticular tuberculosis early, as late diagnosis or inadequate treatment may cause permanent disability.

    Prediabetes, a high-risk state for developing diabetes showing impaired glucose tolerance but a normal fasting blood glucose level, has an increasing prevalence worldwide. However, no study investigating the prevention of impaired glucose tolerance at the prediabetic stage by anti-diabetic functional foods has been reported. Thus, the present study aimed to evaluate the anti-prediabetic effect of rose hip in a prediabetic rat model. Spontaneously diabetic Torii (SDT) rats were supplemented with hot-water extract of rose hip at a dose of 100 mg kg-1 body weight day-1 for 12 weeks. The results obtained showed that the supplementation of rose hip extract improved impaired glucose tolerance, promoted insulin secretion, preserved pancreatic beta-cell function and suppressed plasma advanced glycation end-products formation of methylglyoxal-derived hydroimidazolone (MG-H1) residue and Nϵ -carboxymethyl-lysine residues (e.g. MG-H1, control: 465.5 ± 43.8 versus rose hip: 59.1 ± 13.0 pmol mg protein-1 , P < 0.05) in SDT rats at the prediabetic stage (12-20 weeks old). The present study provides the first evidence showing that a hot-water extract of rose hip could exert an anti-prediabetic effect in a rat model. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    OBJECTIVES: To compare the hip and ankle range of motion and hip muscle strength in 8-11 year old novice female ballet dancers and controls. METHODS: Subjects were 77 dancers and 49 controls (mean (SD) age 9.6 (0.8) and 9.6 (0.7) years respectively). Supine right active hip external rotation (ER) and internal rotation (IR) were measured using an inclinometer. A turnout protractor was used to assess standing active turnout range. The measure of ER achieved from below the hip during turnout (non-hip ER) was calculated by subtracting hip ER range from turnout range, and hip ER:IR was derived by dividing ER range by IR range. Range of right weight bearing ankle dorsiflexion was measured in a standing lunge using two methods: the distance from the foot to the wall (in centimetres) and the angle of the shank to the vertical via an inclinometer (in degrees). Right calf muscle range was measured in weight bearing using an inclinometer. A manual muscle tester was used to assess right isometric hip flexor, internal rotator, external rotator, abductor, and adductor strength. RESULTS: Dancers had less ER (pballetic training.

    Robotic lower limb exoskeletons hold significant potential for gait assistance and rehabilitation; however, we have a limited understanding of how people adapt to walking with robotic devices. The purpose of this study was to test the hypothesis that people reduce net muscle moments about their joints when robotic assistance is provided. This reduction in muscle moment results in a total joint moment (muscle plus exoskeleton) that is the same as the moment without the robotic assistance despite potential differences in joint angles. To test this hypothesis, eight healthy subjects trained with the robotic hip exoskeleton while walking on a force-measuring treadmill. The exoskeleton provided hip flexion assistance from approximately 33% to 53% of the gait cycle. We calculated the root mean squared difference (RMSD) between the average of data from the last 15 minutes of the powered condition and the unpowered condition. After completing three 30-minute training sessions, the hip exoskeleton provided 27% of the total peak hip flexion moment during gait. Despite this substantial contribution from the exoskeleton, subjects walked with a total hip moment pattern (muscle plus exoskeleton) that was almost identical and more similar to the unpowered condition than the hip angle pattern (hip moment RMSD 0.027, angle RMSD 0.134, p<0.001). The angle and moment RMSD were not different for the knee and ankle joints. These findings support the concept that people adopt walking patterns with similar joint moment patterns despite differences in hip joint angles for a given walking speed. PMID:21333995

    To determine the reliability of early passive hip laxity examination in predicting moderate and severe hip dysplasia. The passive hip laxity of 104 Estrela Mountain dogs was evaluated using the Ortolani method, conventional hip-extended radiography and the PennHIP method, when the animals were between four and 12 months of age. After the age of one, dogs were re-examined for hip dysplasia using the Fédération Cynologique Internationale scoring system. The passive hip laxity results were subsequently compared with the Fédération Cynologique Internationale scores for sensitivity, specificity, positive predictive value, negative predictive value and accuracy. The PennHIP method achieved the best results in specificity (93 per cent), positive predictive value (91 per cent) and accuracy (88 per cent), and the Ortolani method was the best in sensitivity (92 per cent) and negative predictive value (92 per cent). The Fédération Cynologique Internationale grades D and E can be predicted with confidence even before animals are one year old.

    We aimed to study the risk of hip fracture and risk of hip arthroplasty among farmers in Sweden. Our results indicate that farming, representing an occupation with high physical activity, in men is associated with a lower risk of hip fracture but an increased risk of hip arthroplasty. The risks of hip fracture and hip arthroplasty are influenced by factors including socioeconomic status, education, urbanization, latitude of residence, and physical activity. Farming is an occupation encompassing rural living and high level of physical activity. Therefore, we aimed to study the risk of hip fracture and risk of hip arthroplasty among farmers in Sweden. We studied the risk of hip fracture, and hip arthroplasty due to primary osteoarthritis, in all men and women aged 35 years or more in Sweden between 1987 and 2002. Documented occupations were available in 3.5 million individuals, of whom 97,136 were farmers. The effects of age, sex, income, education, location of residence, and occupation on risk of hip fracture or hip arthroplasty were examined using a modification of Poisson regression. A total of 4027 farmers and 93,109 individuals with other occupations sustained a hip fracture, while 5349 farmers and 63,473 others underwent a hip arthroplasty. Risk of hip fracture was higher with greater age, lower income, lower education, higher latitude, and urban area for all men and women. Compared to all other occupations, male farmers had a 20% lower age-adjusted risk of hip fracture (hazard ratio (HR) 0.80, 95%CI 0.77-0.84), an effect that was not seen in female farmers (HR 0.96, 95% CI 0.91-1.01). Both male and female farmers had a higher age-adjusted risk for hip arthroplasty. Our results indicate that farming, representing an occupation with high physical activity, in men is associated with a lower risk of hip fracture but an increased risk of hip arthroplasty.

    The purpose of this study was to analyze the effect of 3 different exercise interventions plus a control group on passive hip range of motion (ROM). Previous research studies into the methods of improving passive hip mobility have focused on stretching protocols aimed specifically at the hip joint. The effect of core stabilization, motor training, and myofascial stretching techniques on hip mobility in a selected asymptomatic group with limited hip mobility is unclear. In this study, 24 young men with limited hip mobility (stretching, stretching with motor control exercises for the hip and trunk, core endurance with motor control exercises, and the control group. Six-week home exercise programs were individually prescribed based on the assigned group, hip ROM, movement patterns, and timed core endurance. Two-way analyses of variances were conducted to analyze the effect of group assignment on hip ROM improvements. Both stretching groups demonstrated significant improvements in hip ROM (p stretching also demonstrated a moderate increase in ROM but only significantly so in rotation. Average core endurance holding times improved 38-53%. These results indicate that stretches aimed at the myofascial components of the upper body, in addition to the hip joint, resulted in dramatic increases in hip ROM in a group of young men with limited hip mobility. Hip ROM also improved in the group that did no active stretching, highlighting the potential role of including stabilization or "proximal stiffening training" when rehabilitating the extremities.

    Many attempts have been made to improve the predictive ability of areal bone mineral density (aBMD) which integrates bone mass and area. The addition of an extra variable derived from the hip dual-energy X-ray (DXA) image TR_σ, which describes distribution of mass within the scanned area of the trochanter, improved prediction of 15-year hip fracture probability in elderly women. Two-dimensional DXA imaging of the proximal femur to produce an aBMD is a clinically useful predictor of future fracture risk. Further analysis of the DXA image to produce an eight-variable hip structure analysis (Beck HSA) has been developed to improve understanding of structural factors determining hip bone strength at each of three proximal femur sites, the narrow femoral neck (NN), intertrochanter (TR) and shaft (S). Recently, data on four measurements derived from the currently used eight Beck HSA variables were used to capture population variation in bone structure at each site. These include two previously used variables, the localised aBMD and the sub-periosteal width (W) applying to 5-mm sections (at each sites), and two new variables, standard deviation of normalised mineral-mass projection profile distribution (σ), and displacement between centre-of-mineral mass and geometric centre-of-mineral mass of projection profile (δ). Using a cohort of 1159 women, mean baseline age 75, who sustained 139 hip fractures over 15 years, we determined whether these measures significantly improved 15-year hip fracture prediction compared to current approach utilising age and total hip aBMD. To describe the most parsimonious model for hip fracture risk prediction, the 12 base measures (4 from each site), total hip aBMD and age were evaluated in stepwise logistic regression models. The final model included TR_σ, total hip aBMD and age and provided improved utility for hip fracture prediction compared to total hip aBMD and age alone (C-statistic 0.73 vs. 0.69, P = 0.009 and net

    Total hip arthroplasty with subtrochanteric shortening osteotomy is widely performed for high hip dislocation. However, suboptimal leg length discrepancy correction and nonunion of the osteotomy site remain concerns. Although total hip arthroplasty using trochanteric osteotomy without subtrochanteric osteotomy was introduced, cemented implants have been more commonly used than contemporary cementless implants in this procedure. We evaluated the long-term results of cementless total hip arthroplasty with trochanteric osteotomy without subtrochanteric osteotomy for high hip dislocation. From 1990 to 2002, 27 cementless total hip arthroplasties using trochanteric osteotomy without subtrochanteric osteotomy were performed in 26 patients with Crowe III or IV high hip dislocation and a mean age of 36.4 ± 12.9 years. Seven ceramic-on-ceramic, 8 ceramic-on-polyethylene, 10 metal-on-polyethylene, and 2 metal-on-metal bearings were inserted. Mean follow-up was 15.1 ± 3.7 years. We retrospectively reviewed medical records and radiographic data and evaluated the clinical and radiological results including the Harris hip score, implant survival, correction of leg length discrepancy, and occurrence of complications. The mean Harris hip score and leg length discrepancy improved significantly from 73.3 to 94.9 points and from 4.3 cm to 1.0 cm, respectively. With revision for loosening set as the end point, implant survival rates at 10 and 15 years postoperatively were 96.0% and 90.9% for stems and 74.1% and 52.3% for cups. In 8 of 10 hips with the metal-on-polyethylene bearing and 4 of 8 hips with the ceramic-on-polyethylene bearing, revision surgery was performed for aseptic loosening. However, no revision was performed in hips with the ceramic-on-ceramic bearing or the metal-on-metal bearing. Implant survival was significantly different by the type of bearing surface. Two permanent neurologic complications occurred in patients with a limb lengthening over 3.5 cm. With proper

    Injuries of the hip in the adolescent and young adult athlete are receiving more attention with advances in the understanding of femoroacetabular impingement (FAI), labral pathology, and hip arthroscopy. Labral tears have not been well characterized in rowers. The purposes of this study were (1) to describe the clinical presentation of labral pathology in rowers; (2) to describe the MRI and radiographic findings of labral pathology in rowers; and (3) to determine the likelihood that a rower with labral injury, treated arthroscopically, will return to sport. We conducted a review from August 2003 to August 2010 to identify all rowers with MRI-confirmed intraarticular pathology of the hip presenting to our institution. Baseline demographics, symptoms and physical findings, and location of the labral tear with associated pathology, management, and early followup were recorded. The review yielded a total of 21 hips (18 rowers, three with bilateral labral pathology) with a mean patient age of 18.5 years (range, 14-23 years). Most of the rowers (85%) were female and the series included prep school (44%) and collegiate rowers (56%). Eighteen of the 21 hips (85%) eventually underwent arthroscopic surgery at our institution. A large majority of patients had isolated groin pain (71%) and physical findings consistent with impingement (81%). There was no single, dominant location for the labral tears on MRI. Among the 18 patients who had surgery, 10 (56%) returned to rowing, six (33%) never returned, and return data were not available for two (11%) at a mean of 8 months (range, 3-25 months) after surgery. The repetitive motions of the hip required for rowing may be a factor leading to intraarticular labral injuries in the athletes. Underlying anatomic abnormalities of the hip such as FAI may predispose certain patients to these injuries. However, many patients treated arthroscopically did not return to sport at a mean of 8 months after surgery.

    Metal-on-metal (MoM) hip arthroplasties have been utilised over the last 15 years to restore hip function for 1.5 million patients worldwide. Althoug widely used, this hip arthroplasty releases metal wear debris which lead to muscle atrophy. The degree of muscle wastage differs across patients ranging from mild to severe. The longterm outcomes for patients with MoM hip arthroplasty are reduced for increasing degrees of muscle atrophy, highlighting the need to automatically segment pathological muscles. The automated segmentation of pathological soft tissues is challenging as these lack distinct boundaries and morphologically differ across subjects. As a result, there is no method reported in the literature which has been successfully applied to automatically segment pathological muscles. We propose the first automated framework to delineate severely atrophied muscles by applying a novel automated segmentation propagation framework to patients with MoM hip arthroplasty. The proposed algorithm was used to automatically quantify muscle wastage in these patients.

    Full Text Available Hip joint instability and impingement are the most common biomechanical risk factors that put the hip joint at risk to develop premature osteoarthritis. Several surgical procedures like periacetabular osteotomy for hip dysplasia or hip arthroscopy or safe surgical hip dislocation for femoroacetabular impingement aim at restoring the hip anatomy. However, the success of joint preserving surgical procedures is limited by the amount of pre-existing cartilage damage. Biochemically sensitive MRI techniques like delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC might help to monitor the effect of surgical or non-surgical procedures in the effort to halt or even reverse joint damage.

    The aim of the treatment is reduction of hip pain through arthroscopic synovectomy of the hip joint, reduction in activity of the synovial disease and removal of loose bodies in chondromatosis. Synovialitis of the hip due to synovial disease, such as pigmented villonodular synovitis (PVNS) and chondromatosis, synovialitis of the hip due to a further diseases of the hip. The disease must be treatable by arthroscopy (e.g. femoroacetabular impingement and lesion of the acetabular labrum). Suspicion of malignant synovial disease, extensive synovitis, especially in those areas of the hip which are difficult to reach or inaccessible to arthroscopy, primary disease not sufficiently treatable by arthroscopy, e.g. coxarthrosis. Arthroscopy of the central compartment of the hip is carried out by lateral, anterolateral (alternatively inferior anterolateral) and posterolateral portals, using all portals both for the camera and for instruments. In the central compartment synovectomy of the acetabular fossa is performed. A shaver and/or a high frequency diathermy applicator (HF applicator) are employed for removal of the synovial membrane. For arthroscopy of the peripheral compartment lateral, anterolateral (alternatively inferior anterolateral) and superior anterolateral portals are established and all portals are used both for the camera and instruments. In the peripheral compartment, the synovial membrane of the anterior, anteromedial, anterolateral and as far as possible posterolateral areas of the hip is removed. The dorsolateral synovial plica needs to be spared. Non-steroidal anti-inflammatory drugs (NSAIDs) are administered as prophylaxis of heterotopic ossification for 10 days. Contraindications for NSAIDs need to be considered. Thrombosis prophylaxis with low molecular weight heparin over 5 days. Mobilization with full weight bearing. Intensive physiotherapeutic exercises for at least 6 and possibly up to 12 postoperative weeks. Radiosynoviorthesis 6-8 weeks after

    Full Text Available History of present illness: A 24-year-old male was brought in by paramedics status post motor vehicle collision (MVC into an electric pole and tree at high speed. The patient was an unrestrained driver who required extrication. The patient complained of left hip pain, left foot pain, and difficulty extending his bilateral lower extremities. He denied numbness or tingling to his lower extremities. The patient had normal vitals; his bilateral lower extremities were held in flexion at the hips, but otherwise had no obvious injuries. The patient’s pelvis was stable with palpable distal pulses and intact motor and sensory function of his distal lower extremities. Significant findings: The initial radiograph of the pelvis revealed bilateral hip dislocations. Small bony fragments were noted in the right hip joint, suggestive of an underlying fracture. The sacroiliac joints and the pelvic ring were intact. In the emergency department, bilateral hip reductions were performed using the Captain Morgan technique.1 The post-reduction film showed reduction of the bilateral hip dislocations with extensive comminuted and displaced fractures of the right and left acetabula. Discussion: Bilateral hip dislocations are extremely rare, occurring in only 1% of all hip dislocations,2 and require immense force, typically occurring in MVCs (74%.3-7 Associated injuries include fracture of the acetabulum or femoral head, sciatic nerve damage, and obstruction of the blood supply to the femoral head.8 X-ray imaging and CT scans are used to assess the injury and to detect intra-articular fragments.3 Definitive treatment is achieved by closed reduction if possible; otherwise open reduction is utilized.9 Post-reduction therapy includes a non-weight-bearing period of time. Complications include avascular necrosis of the femoral head, osteonecrosis, and posttraumatic arthritis, the occurrence of which can be decreased by early reduction.4,10-12 This patient underwent bilateral

    The purpose of our study was to identify the clinical and radiologic factors associated with a positive culture during image-guided hip joint aspiration. We performed a retrospective analysis of 167 consecutive hip aspirations for septic arthritis at a large tertiary medical center. Chart review was performed on the following clinical factors: serum WBC count≥11×10(3)/μL, serum erythrocyte sedimentation rate (ESR)≥20 mm/h, C-reactive protein (CRP)≥100 mg/L, synovial fluid WBC count, synovial fluid polymorphonuclear (PMN) leukocytes≥90%, fever, immunosuppression, antibiotic use, diabetes, presence of a prosthesis, and IV drug use (IVDU). Radiologic studies were reviewed for the following imaging and technical factors: presence of a sinus tract, fluid turbidity, volume of fluid (mL) aspirated, and whether the fluid analyzed was primarily aspirated or reaspirated after lavage. Logistic regression was used to calculate odds ratio (OR) and 95% CI. Of the 167 aspirations, 29 (17.4%) had positive cultures; 6 of 29 (20.7%) positive cultures occurred in reaspirated lavage fluid. On multivariate analysis using logistic regression with stepwise backward elimination, the significant clinical and radiologic predictors were elevated WBC (OR, 4.4; 95% CI, 1.1-17.3), high percentage of synovial fluid PMN leukocytes (OR, 10.6; 95% CI, 2.9-39.8), IVDU (OR, 9.0; 95% CI, 1.3-64.7), and fluid turbidity (OR, 20.5; 95% CI, 6.9-61.4). Positive hip cultures are associated with elevated serum WBC, IVDU, high percentage of synovial fluid PMN leukocytes, and fluid aspirate turbidity. Reaspiration of lavage fluid with either nonbacteriostatic saline or contrast material can yield positive cultures.

    Hip fracture in the elderly often occurs in patients with high co-morbidity. Effective management requires a comprehensive and multidisciplinary approach. To evaluate the effect of a quality improvement intervention in the detection and treatment of complications in elderly patients admitted for hip fracture. A comparative study was conducted between two groups of patients admitted for hip fracture prior to 2010, and after a quality improvement intervention in 2013. The intervention consisted of implementing improved multidisciplinary measures in accordance with recent scientific evidence. The degree of compliance of the implemented measures was quantified. Patients admitted due to hip fracture in 2010 (216 patients) and 2013 (196 patients) were similar in age, sex, Barthel Index, and a reduced Charlson Index, although there were more comorbidities in 2013. After implementation of the protocols, the detection of delirium, malnutrition, anemia, and electrolyte disturbances increased. A larger number of patients in 2013 were precribed intravenous iron (24% more) and osteoporosis treatment (61.3% more). The average stay was reduced by 45.3% and surgical delay by 29.4%, achieving better functional efficiency. The implementation of a clinical pathway in geriatric patients with hip fracture is useful to detect and treat complications at an early stage, and to reduce pre-operative and overall stay, all without a negative clinical or functional impact.

    2016-01-01

    Context: Successful treatment of nonarthritic hip pain in young athletic individuals remains a challenge. A growing fund of clinical knowledge has paralleled technical innovations that have enabled hip preservation surgeons to address a multitude of structural variations of the proximal femur and acetabulum and concomitant intra-articular joint pathology. Often, a combination of open and arthroscopic techniques are necessary to treat more complex pathomorphologies. Peri- and postoperative recovery after such procedures can pose a substantial challenge to the patient, and a dedicated, thoughtful approach may reduce setbacks, limit morbidity, and help optimize functional outcomes. Evidence Acquisition: PubMed and CINAHL databases were searched to identify relevant scientific and review articles through December 2014 using the search terms hip preservation, labrum, surgical dislocation, femoroacetabular impingement, postoperative rehabilitation, peri-acetabular osteotomy, and rotational osteotomy. Reference lists of included articles were reviewed to locate additional references of interest. Study Design: Clinical review. Level of Evidence: Level 4. Results: Hip preservation procedures and appropriate rehabilitation have allowed individuals to return to a physically active lifestyle. Conclusion: Effective postoperative rehabilitation must consider modifications and precautions specific to the particular surgical techniques used. Proper postoperative rehabilitation after hip preservation surgery may help optimize functional recovery and maximize clinical success and patient satisfaction. PMID:26733593

    To evaluate the evidence for the resuscitation of patients with hip fracture in the preoperative or perioperative phase of their treatment and its impact on mortality. We searched MEDLINE, EMBASE, CENTRAL and PROSPERO databases using a systematic search strategy for randomised trials and observational studies investigating the fluid resuscitation of any patient with hip fracture. No language limits were applied to the search, which was complemented by manually screening the reference lists of appropriate studies. Mortality at 1 week, 30 days and 1 year following surgery. Two hundred and ninety-eight citations were identified, and 12 full manuscripts were reviewed; no studies satisfied the inclusion criteria. The background literature showed that the mortality for these patients at 30 days is approximately 8.5% and that bone cement implantation syndrome is insufficient to explain this. The literature was explored to define the need for an interventional investigation into the preoperative resuscitation of patients with hip fracture. Patients with hip fracture show similar physiological disturbance to major trauma patients. Nineteen per cent of patients presenting with hip fracture are hypoperfused and 50% show preoperative anaemia suggesting that under resuscitation is a common problem that has not been investigated. A properly conducted interventional trial could improve the outcome of these vulnerable patients. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To discuss the clinical significance of the most common hip and groin injuries in baseball players, as well as an algorithmic approach to diagnosis and treatment of these injuries. (a) Limitations in throwing velocity, pitch control, and bat swing speed may be secondary to decreased mobility and strength within the proximal kinetic chain, which must harness power from the lower extremities and core. (b) Approximately 5.5% of all baseball injuries per year involve the hip/groin and may lead to a significant amount of time spent on the disabled list. Injuries involving the hip and groin are relatively common in baseball players. Our knowledge of the mechanics of overhead throwing continues to evolve, as does our understanding of the contribution of power from the lower extremities and core. It is paramount that the team physician be able to accurately diagnose and treat injuries involving the hip/groin, as they may lead to significant disability and inability to return to elite levels of play. This review focuses on hip- and groin-related injuries in the baseball player, including femoroacetabular impingement, core muscle injury, and osteitis pubis.

    We defined the characteristics of dysplasia and coxa valga in hereditary multiple exostoses (HME) by radiological analysis of 24 hips in 12 patients. The degree and effect of the 'osteochondroma load' around the hip were quantified. We investigated the pathology of the labrum and the incidence of osteoarthritis and of malignant change in these patients. Coxa valga and dysplasia were common with a median neck-shaft angle of 156 degrees, a median centre-edge angle of 23 degrees and Sharp's acetabular angle of 44 degrees. There was overgrowth of the femoral neck with a significantly greater ratio of the neck/shaft diameter in HME than in the control hips (p coxa valga (p coxa valga. No correlation was found between dysplasia and coxa valga. These data suggest that HME may cause anomalies of the hip as a reflection of a generalised inherited defect, but also support the theory that osteochondromas may themselves precipitate some of the characteristic features of HME around the hip.

    Hip fracture is often complicated by depressive symptoms in older adults. We sought to characterize trajectories of depressive symptoms arising after hip fracture and examine their relationship with functional outcomes and walking ability. We also investigated clinical and psychosocial predictors of these trajectories. We enrolled 482 inpatients, aged ⩾60 years, who were admitted for hip fracture repair at eight St Louis, MO area hospitals between 2008 and 2012. Participants with current depression diagnosis and/or notable cognitive impairment were excluded. Depressive symptoms and functional recovery were assessed with the Montgomery-Asberg Depression Rating Scale and Functional Recovery Score, respectively, for 52 weeks after fracture. Health, cognitive, and psychosocial variables were gathered at baseline. We modeled depressive symptoms using group-based trajectory analysis and subsequently identified correlates of trajectory group membership. Three trajectories emerged according to the course of depressive symptoms, which we termed 'resilient', 'distressed', and 'depressed'. The depressed trajectory (10% of participants) experienced a persistently high level of depressive symptoms and a slower time to recover mobility than the other trajectory groups. Stressful life events prior to the fracture, current smoking, higher anxiety, less social support, antidepressant use, past depression, and type of implant predicted membership of the depressed trajectory. Depressive symptoms arising after hip fracture are associated with poorer functional status. Clinical and psychosocial variables predicted membership of the depression trajectory. Early identification and intervention of patients in a depressive trajectory may improve functional outcomes after hip fracture.

    The role of hip arthroscopic surgery in dysplasia is controversial. To determine the 7-year joint preservation rate after hip arthroscopic surgery in hip dysplasia and identify anatomic and intraoperative features that predict the success of hip preservation with arthroscopic surgery, allowing the formulation of an evidence-based classification system. Case-control study; Level of evidence, 3. Between 2008 and 2013, 111 hips with dysplastic features (acetabular index [AI] >10° and/or lateral center-edge angle [LCEA] arthroscopic surgery were identified. Clinical, radiological, and operative findings and the type of procedure performed were reviewed. Radiographic evaluations of the operated hip (AI, LCEA, extrusion index) were performed. Outcome measures included whether the hip was preserved (ie, did not require arthroplasty) at follow-up and the preoperative and postoperative Non-Arthritic Hip Score (NAHS) and Hip disability and Osteoarthritis Outcome Score (HOOS). The AI and LCEA were calculated, factored by a measure of articular wear (AIf and LCEAf, respectively), according to the University College Hospital, London (UCL) grading system as follows: AIf = AI × (number of UCL wear zones + 1), and LCEAf = LCEA / (number of UCL wear zones + 1). A contour plot of the resulting probability value of failure for every combination of AIf and LCEAf allowed for the determination of the zones with the lowest and highest incidences of failure to preserve the hip. The mean AI and LCEA were 9.8° and 18.0°, respectively. At a mean follow-up of 4.5 years (range, 0.4-8.3 years), 33 hips had failed, requiring hip arthroplasty. The 7-year joint survival rate was 68%. The mean improvements in the NAHS and HOOS were 11 ( P = .001) and 22.8 ( P arthroscopic surgery is associated with an excellent chance of hip preservation in mild dysplasia (green zone: AI = 0°-15°, LCEA = 15°-25°) and no articular wear. The authors advise that the greatest caution should be used when

    home. The other trial compared anabolic steroid injections every three weeks for six months and daily protein supplementation versus control in 40 "lean elderly women". Both trials found some evidence of better function in the steroid plus group. One trial reported greater independence, higher Harris hip scores and gait speeds in the steroid plus group at 12 months. The second trial found fewer participants in the anabolic steroid group were either dependent in at least two functions, including bathing, or dead at six and 12 months (one person in the control group died) (1/17 versus 7/18; RR 0.15, 95% CI 0.02 to 1.10; P = 0.06). Pooled mortality data (2/51 versus 3/51) from the two trials showed no evidence of a difference between the two groups at one year. Similarly, there was no evidence of between-group differences in individual adverse events. Three participants in the steroid group of one trial reported side effects of hoarseness and increased facial hair. The other trial reported better quality of life in the steroid plus group. The available evidence is insufficient to draw conclusions on the effects, primarily in terms of functional outcome and adverse events, of anabolic steroids, either separately or in combination with nutritional supplements, after surgical treatment of hip fracture in older people. Given that the available data points to the potential for more promising outcomes with a combined anabolic steroid and nutritional supplement intervention, we suggest that future research should focus on evaluating this combination.

    Full Text Available We performed dynamic hip doppler ultrasonography in children with Legg-Calve-Perthes disease (LCPD in order to determine the effectiveness of the conservative and surgical treatment. The study included children aged from 3 to 7 years old with LCPD who had pain in the hip joints during admission. We assessed the structural changes in the head of the femur and the hip joint (B-mode, when the Doppler study analyzed diameter of enveloping hip vessels, blood velocity and resistance index. The study found that severe pain and contracture of the hip during admission appeared as a manifestation of concomitant hip osteoarthritis. On admission all patients had signs of arterial spasm and venous stasis in the hip joints, which determined the administration of a comprehensive arthrologic, osteogenesis stimulating and angioprotective therapy, according to the data of dynamic ultrasound.

    A retrospective analysis of 52 patients with hip pain following total hip replacement was made. Each of them was evaluated by plain radiographs, technetium 99m pyrophosphate scans, arthrography with plain film substraction technique, and culture of joint fluid. In 30 cases there was evidence of prosthetic loosening, and in 21 of these lymphangeal opacification during arthrography was seen. In 15 cases with lymphongeal opacification the daignosis of prosthetic loosening was subsequently confirmed by prosthetic revision. In none of the 22 cases in which no evidence of prosthetic loosening was seen was there lymphatic opacification. It is concluded that lymphatic opacification during arthrography for pain following total hip prosthesis is a valuable ancillary sign of loosening. (orig.).

    Full Text Available Osteoblastoma occurring in the region of the hip is very rare, and vague symptoms with uncharacteristic radiographic features often lead to misdiagnosis. Because of radiographic and histological similarities, it must be carefully distinguished from osteoid osteoma, aneurysmal bone cyst, giant cell tumor, and osteosarcoma. Computed tomography is the preferred imaging modality as it is able to detect the nidus and images will not exhibit the flare phenomenon caused by surrounding inflammation seen with magnetic resonance imaging. For hip joint lesions in weight-bearing areas, intralesional curettage may achieve satisfactory outcomes as compared with wide resection. We herein report two cases of osteoblastoma in the hip region in which diagnosis was delayed that were successfully treated with curettage and followed by high-speed burring.

  16. Hip Pain: Dry Needling Versus Cortisone Injections.

    Science.gov (United States)

    2017-04-01

    Greater trochanteric pain syndrome (GTPS) is chronic, intermittent pain and tenderness on the outside of the hip. The medical community once thought that a swollen hip bursa was the source of such pain, which led to the use of corticosteroid injections to the bursa to help decrease swelling and pain. However, researchers now believe that injuries to the muscles and tendons around the hip are the actual cause of this pain, and that inflammation is often not involved. A study published in the April 2017 issue of JOSPT explores dry needling as an alternative to cortisone injections to reduce pain and improve function in patients with GTPS.

    Spontaneous hip lateralization complicates the management of non-ambulatory children with cerebral palsy (CP). It can be diagnosed early using radiographs, but it involves standardization of positioning and exposure to radiation. Hence, the aim of this study was to assess the utility of Combined hip abduction angle (CHAA) in the clinical setting to identify those children with CP who were at greater risk to develop spontaneous progressive hip lateralization. One hundred and three children (206 hips) with CP formed our study population. There were 48 boys and 55 girls aged 2-11 years (mean 5.03 years). 61 children were Gross Motor Function Classification System (GMFCS) level 5, while 42 were GMFCS level 4. Clinical measurements of CHAA were statistically correlated with radiographic measurements of Reimer's migration percentage (MP) for bivariate associations using χ(2) and t tests. CHAA is evaluated against MP which is considered as a reliable measure of hip subluxation. Thus, for CHAA, sensitivity was 74.07% and specificity was 67.35%. False-positive rate was 32.65% and false-negative rate was 25.93%. Our study shows that correlation exists between CHAA and MP, which has been proved to be useful for hip screening in CP children at risk of hip dislocation. CHAA is an easy, rapid, cost-effective clinical test which can be performed by paraclinical health practitioners (physiotherapists) and orthopedic surgeons.

    Full Text Available The purpose of the study was to analyze the medium- and long-term results of hip arthroplasty using Paavilainen technique in patients with the congenitally dislocated hip. Methods: From 2001 to 2012 180 operations were carried out were using the Paavilainen technique in 140 patients with high dislocation of the hip (Crowe IV. All patients were clinically evaluated using the Harris Hip Score (HHS, VAS and radiography. Statistical analysis was performed using the Pearson correlation coefficients, multiple regression analysis and classification trees analysis. Results: The average Harris score improved from preoperative 41.6 (40,3-43,5 to 79.3 (77,9-82,7 at final follow-up, and the difference was significant. Early complications were 9% (the most frequent were fractures of the proximal femur, later - 16.7% (pseudoarthrosis of the greater trochanter, 13.9%; disclocations-1,1%, aseptic loosening of the components - 1.7%, reoperation performed in 8.3% of cases. Such factors as age and limb length has statistically significant effect on functional outcomes. Established predictive model allows to get the best possible functional outcome in such patients with severe dysplasia. Conclusions: Total Hip arthroplasty using the Paavilainen technique is an effective method of surgical treatment in patients with the congenitally dislocated hip, but it is technically difficult operation with a high incidence of complications in comparison with standard primary total hip replacement.

    Hip arthroscopy is a minimally invasive surgical technique often performed in athletes who want an expeditious return to sport. To the authors' knowledge, no studies in the literature provide a time frame or criteria for return to sport after hip arthroscopy. The purpose of this study was to develop an aggregate recommendation for return to sport after hip arthroscopy based on data assimilated from high-volume hip arthroscopy centers. Twenty-seven orthopedic surgeons from high-volume hip arthroscopy centers completed a survey regarding return to sport after hip arthroscopy. The questionnaire asked surgeons to give a time frame for return to sport and to choose meaningful criteria that an athlete must meet prior to return to sport. Surgeons were asked to categorize various common sports as high, medium, or low risk with regard to the hip. The aggregate results were used to create standardized recommendations for time, criteria, and risk for return to competitive sports. Regarding time frame for return to sport, 70% of surgeons recommended 12 to 20 weeks. In addressing criteria for return to sport, 85% of surgeons recommended that patients need to be able to reproduce all motions involved in their sport without pain. A majority of surgeons recommended criteria of pain-free running, jumping, lateral agility drills, and single-leg squats. Finally, surgeons categorized sports requiring the most movement and impact of the hip joint (football, basketball, wrestling, and martial arts) as high-risk sports. Sports with less impact on the hip, such as golf, were ranked as low risk. Copyright 2014, SLACK Incorporated.

    Full Text Available CONTEXT: Rehabilitation following hip arthroscopy is an integral component of the clinical outcome of the procedure. Given the increase in quantity, complexity, and diversity of procedures performed, a need exists to define the role of rehabilitation following hip arthroscopy.OBJECTIVES: 1 To determine the current rehabilitation protocols utilized following hip arthroscopy in the current literature, 2 to determine if clinical outcomes are significantly different based on different post-operative rehabilitation protocols; and 3 to propose the best-available evidence-based rehabilitation program following hip arthroscopy.DATA SOURCES: Per PRISMA guidelines and checklist, Medline, SciVerse Scopus, SportDiscus, and Cochrane Central Register of Controlled Trials were searched.STUDY SELECTION: Level I-IV evidence clinical studies with minimum two-year follow-up reporting outcomes of hip arthroscopy with post-operative rehabilitation protocols described were included. DATA EXTRACTION: All study, subject, and surgery parameters were collected. All elements of rehabilitation were extracted and analyzed. Descriptive statistics were calculated. Study methodological quality was analyzed using the Modified Coleman Methodology Score (MCMS.RESULTS: 18 studies were included (2,092 subjects; 52% male, mean age 35.1 +/- 10.6 years, mean follow-up 3.2 +/- 1.0 years. Labral tear and femoroacetabular impingement were the most common diagnoses treated and labral debridement and femoral/acetabular osteochondroplasty the most common surgical techniques performed. Rehabilitation protocol parameters (weight-bearing, motion, strengthening, and return-to-sport were poorly reported. Differences in clinical outcomes were unable to be assessed given heterogeneity in study reporting. Time-, phase-, goal-, and precaution-based guidelines were extracted and reported.CONCLUSIONS: The current literature of hip arthroscopy rehabilitation lacks high-quality evidence to support a

    Full Text Available We developed a new povidone iodine coating technology for titanium hip implants and performed a clinical trial to assess its usefulness in suppressing postoperative infection. Results indicate that iodine-supported titanium has favorable antibacterial activity, biocompatibility, and no cytotoxicity. Thirty joints in 28 patients were treated using iodine-supported implants. Fourteen joints were revision total hip arthroplasty (THA after periprosthetic infection, 13 were primary THA for immunosuppressive conditions or pyogenic arthritis, and 3 were conversions from hemiarthroplasty to THA for immunosuppressive conditions. Two examinations were conducted sequentially until final follow-up: white blood cell (WBC and C-reactive protein (CRP were measured pre- and postoperatively and thyroid hormone levels in the blood were examined. The mean follow-up period was 33 months (14–78. There were no signs of infection in any patient at the last follow-up. WBC and CRP levels returned to normal within several weeks. No abnormalities of thyroid gland function were detected. Loosening of the implants did not occur in any patient. Excellent bone ingrowth and ongrowth were found around prostheses. No cytotoxicity or adverse effects were detected. These results suggest that iodine-supported THA implants can be highly effective in preventing and treating postoperative infections.

    Following total hip arthroplasty, patients demonstrate compensatory movement strategies during activities of daily living such as walking and stair climbing. Movement compensations are important markers of functional decline in older adults and are related to poor functional capacity. Despite increased utilization of hip arthroplasty, persistent movement compensation, and functional performance deficits, no consensus on postoperative rehabilitation exists. Neuromuscular reeducation techniques offer a strategy to improve movement quality by emphasizing hip abductor performance and pelvic stability. This case series illustrates changes in movement strategy around the hip in response to targeted neuromuscular reeducation techniques after hip arthroplasty. Five participants received an 8-week exercise program following total hip arthroplasty, emphasizing targeted neuromuscular reeducation techniques hallmarked by specific, weight-bearing exercise to improve hip abductor performance and pelvic stability. Five additional participants were supervised and followed for comparison. Participants in the neuromuscular reeducation program improved their internal hip abductor moments and vertical ground reaction forces during walking and stair climbing. They also improved their functional performance and hip abductor strength outcomes. Targeted neuromuscular reeducation techniques after total hip arthroplasty provided a positive effect on biomechanical outcomes, functional performance, and muscle strength. Through focused use of the hip abductor muscles, increased internal hip abductor moments were observed. This intervention potentially promotes pelvic stability, and may contribute to improved performance on tasks such as stair climbing, fast walking, and balance. The results suggest that neuromuscular reeducation offers a unique effect on movement strategy and function for patients following total hip arthroplasty. Copyright © 2016 Elsevier Ltd.

    2011-01-01

    Dancers are quite prone to injuries in the hip region. Imaging plays a key role in evaluation of the pain resulting from such injuries, as proximity of structures and cross-innervation can result in a clinical dilemma regarding the specific injury, and thus origin of the pain generator. Advanced imaging techniques, including MRI, ultrasound, and multidetector CT, are becoming increasingly important in the workup of injuries in athletes, yet radiographs remain an essential component. This article presents a variety of injuries in the hip and groin region that may be seen in dancers and discusses the utility of basic and advanced imaging modalities.

    Hip fractures account for coxa vara in 3 (13%) and coxa valga in 2 (9%). There was no nonunion. Poor outcomes were related to the development of osteonecrosis. The time to surgery (≤ 12 hours) and the quality of reduction significantly influenced the occurrence of osteonecrosis. The occurrence and severity of femoral head osteonecrosis significantly influenced the functional results (p < 0.001, and p < 0.048, respectively). Osteonecrosis is the most severe complication after hip fractures in children and is associated with poor functional results. The time to surgery and the quality of reduction were the significant predictors in our study.

  9. Usefulness of ultrasonography in the diagnosis of hematoma after primary hip arthroplasty

    Full Text Available Introduction: To date, suction drainage has been routinely used after hip joint replacement. Currently, the validity of this practice is questioned in the literature. Hematoma is a risk factor of periprosthetic infection. Post-operative ultrasonography enables precise assessment of hip joint hematoma. Aim: The aim of the study was to evaluate the usefulness of hip joint ultrasonography with respect to the validity of using suction drainage after primary hip arthroplasty. Material: Inclusion criteria: coxarthrosis. Exclusion criteria: primary and secondary coagulopathy, renal or hepatic failure and history of venous or arterial thrombosis. In total, 90 patients were enrolled. Methods: The study was prospective. The patients were assigned into groups in accordance with simple randomization. On the third day postsurgery, an ultrasound examination was conducted in all patients. Results: Deep infection was found in two patients with suction drainage. Hematoma was almost twice bigger in the drainage group. There were no statistically significant differences in the Harris Hip Score between the groups. No statistically significant differences were found between the groups in: complete blood count parameters and C-reactive protein values in the first and third day after surgery, the amount of transfused packed red blood cells, duration of hospital stay, cost of hospital stay and the relationship between osteophyte removal and hematoma size. Conclusions: Ultrasonography performed after hip replacement surgeries is useful in the assessment of hematoma. The randomized study did not reveal statistically significant differences between the group with and without drainage, thus suggesting that this practice can be abandoned, except for selected cases. Due to a short hospital stay, it is recommended to conduct an ultrasound scan in addition to routine radiography and laboratory tests in order to reduce the risk of complications.

    Elderly people, due to neurological conditions and muscular atrophy, present a greater propensity to falls and thus are very susceptible to hip fractures. Other variables, such as osteoporosis, may also be related to the etiopathogenesis of hip fractures, although osteoporosis is in fact a concurrent disease, and merely a coadjutant cause. Nonetheless, osteoporosis can make fracture patterns more severe and interfere with osteosynthesis. Osteoporosis is the radiological image of osteopenia, a pathological concept meaning a smaller quantity of bone per unit of volume. The radiological expression of osteopenia is therefore that of bone tissue with a lower radiological density than normal. In the context of hip fractures, bone mineral density and bone architecture of the femoral neck together with protein expression profiles and cross-links of this anatomical area are of special interest which is reviewed in the current paper. Spatial variations in bone mineral density in the femoral neck were found in the literature with increased porosity from the periosteal to the endosteal region and also from the distal to the proximal part of the femoral neck. Furthermore, increased crystal size, increased cortical porosity, reduced osteocyte lacunar density and an increased Ca/P ratio associated with higher concentrations of Ca and P were described in hip fracture patients compared to control patients. Osteocalcin/collagen type 1 expression ratio and enzymatic cross-link content in high-density bone was found to be significantly lower in hip fractures compared to controls. In conclusion, further research in bone mineral density and associated parameters are of interest to deepen the understanding of osteoporotic hip fractures. Copyright © 2016 Elsevier Ltd.

    tetramers both in the crystal and in solution. The tetramers are composed of four helix-loop-helix motifs with the loop regions connecting the helices displaying a high degree of flexibility. Owing to interactions at the tetramer interface, the observed tetramer can be described as a dimer of dimers. We...... identified three residues at the tetramer interface (Leu84, Leu88, Tyr95), which due to largely non-polar side-chains, could be important determinants for protein oligomerization. Based on these observations, we produced a sHIP variant in which these residues were mutated to alanines. Biophysical experiments...... clearly indicated that the sHIP mutant appear only as dimers in solution confirming the importance of the interfacial residues for protein oligomerisation. Furthermore, we could show that the sHIP mutant interacts with intact histidine-rich glycoprotein (HRG) and the histidine-rich repeats in HRG...

    Almost 30% of hip fractures occur in men; the mortality, morbidity, and loss of independence after hip fractures are greater in men than in women. To comprehensively evaluate risk factors for hip fracture in older men, we performed a prospective study of 5994 men, primarily white, age 65+ years recruited at six US clinical centers. During a mean of 8.6 years of 97% complete follow-up, 178 men experienced incident hip fractures. Information on risk factors including femoral neck bone mineral density (FNBMD) was obtained at the baseline visit. Cox proportional hazards models were used to calculate the hazard ratio (HR) with 95% confidence intervals; Fine and Gray models adjusted for competing mortality risk. Older age (≥75 years), low FNBMD, currently smoking, greater height and height loss since age 25 years, history of fracture, use of tricyclic antidepressants, history of myocardial infarction or angina, hyperthyroidism or Parkinson's disease, lower protein intake, and lower executive function were all associated with an increased hip fracture risk. Further adjustment for competing mortality attenuated HR for smoking, hyperthyroidism, and Parkinson's disease. The incidence rate of hip fracture per 1000 person-years (PY) was greatest in men with FNBMD T-scores hip fracture at rates of 14.52 versus 0.88 per 1000 PY in men age hip fracture. Many of these assessments can easily be incorporated into routine clinical practice and may lead to improved risk stratification. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and Mineral Research.

    Guss, Michael; Youm, Thomas

    2017-05-01

    Hip dysplasia, when significant, is effectively treated with periacetabular osteotomy. There have been good results reported with hip arthroscopy when dysplasia is mild. However, when dysplasia is significant, hip arthroscopy with labral repair alone has led to poor results and even rapid decline to end stage arthritis. Staged hip arthroscopy and periacetabular osteotomy would potentially treat the labral lesion and correct the underlying bony abnormality that resulted in the labral pathology. Such a staged treatment plan should help prevent progression to degenerative joint disease. We report a case of a 33-year-old woman who presented with left hip pain and was diagnosed with mild hip dysplasia and a labral tear. She underwent staged hip arthroscopy and labral repair followed by periacetabular osteotomy 2 weeks later. Three and a half months after surgery she developed constant pain and began limping at 5 months. Radiographs showed progression to severe degenerative joint disease. The patient was indicated for total hip arthroplasty.

    Coxa valga and femoral anteversion often are seen in patients with spastic hip displacement and osteotomy is recommended. However, the relationship between femoral deformities and hip displacement has not been clearly defined and other factors, such as joint motion and posture, should be considered before recommending treatment. For children with cerebral palsy with Gross Motor Function Classification System Level IV or V, we questioned (1) whether hip abduction range correlates with hip displacement, (2) what the relationships are between proximal femoral deformities and hip displacement, and (3) whether the patient with a windblown posture has greater degrees of femoral anteversion? We retrospectively studied 31 consecutive children with cerebral palsy with Level IV or V gross motor function who underwent three-dimensional CT for preoperative assessment of hip displacement between January 2010 and December 2013. Among the children, 23 had a windblown posture and eight had symmetric hip motion. Femoral anteversion and true neck-shaft angle were measured from the three-dimensional CT images. Migration percentage was the dependent variable we chose to study in relation to femoral anteversion, neck-shaft angle, maximal hip abduction, and hip flexion contracture, using correlations and multiple linear regressions. Using ANOVA and Scheffé's post hoc tests, we analyzed and compared the data of 23 abducted hips and 23 adducted hips in the 23 children with windblown posture and in 16 displaced hips in the eight children with symmetric hip abduction. Greater migration percentage was associated with less hip abduction range (r = -0.86; p < 0.001). Femoral anteversion had a weak correlation (r = 0.28; p < 0.05) to migration percentage, and the association became insignificant after considering hip abduction motion. Adducted windblown hips had greater femoral anteversion than the symmetric displaced hips and abducted windblown hips (46° vs 36° and 38°, respectively; p < 0

    Evaluation of pain following total hip arthroplasty (THA) can be challenging in the absence of radiographic pathology. This study aimed to examine the diagnostic utility of magnetic resonance imaging (MRI) in the evaluation of enigmatic hip pain following THA. We reviewed a series of patients who were evaluated with MRI after presenting with enigmatic hip pain following THA. MRI was able to demonstrate pathology in the periprosthetic tissues in all hips with minimal artifact. Patients underwent a range of conservative and operative interventions depending on the underlying pathology. If used discriminately in situations where pathology cannot be detected by conventional methods, MRI is a highly effective modality that can aid in the diagnosis of a wide range of disorders thereby allowing the clinician to determine the most appropriate intervention.

    The disease activity score including 28 joints (DAS28), the simplified disease activity index and the clinical disease activity index (CDAI) were developed in order to provide a quantifiable measure of rheumatoid arthritis (RA) activity. Although inflamed hip joints greatly impact activities of daily living (ADL) and walking ability, the hip joint was not included in the DAS28, SDAI or CDAI assessments. Although excellent clinical results have been reported for total hip arthroplasty (THA) in RA patients, correlations between disease activity and hip function in RA patients after THA remain unknown. We analysed the effect of RA disease activity on a hip function score in an observational cohort of RA patients after THA. Twenty-five registered RA patients who had undergone THA (33 joints) were included. Hip function was recorded and RA disease activity was measured on the same day. The mean age of the patients was 65.17 years. They were followed up for a mean of 5.24 years after surgery. The mean duration of disease following RA diagnosis for this patient group was 19.47 years. The Japanese Orthopaedic Association (JOA) hip score was used as a clinical outcome measure for hip dysfunction. RA disease activity and health-related quality of life were measured using the DAS28, SDAI, CDAI and the modified health assessment questionnaire (MHAQ). The mean JOA score for hip function was 80.48 at the final follow-up. The mean DAS28-ESR, DAS28-CRP, SDAI, CDAI and MHAQ measuring RA disease activity levels were 3.38, 2.65, 9.59, 8.63 and 0.44, respectively, at the final follow-up. There was a significant negative correlation between the JOA hip score and all disease activity assessments observed after THA (DAS-ESR [P = 0.0067], DAS-CRP [P = 0.0008]), SDAI [P = 0.0034], CDAI [P = 0.0003]) and MHAQ [P = 0.0002]). We found significant negative correlations between JOA hip scores and all disease activity assessments in RA patients treated with THA.

    Full Text Available Objectives: This study sought to assess the value of differing pre-operative measures in prediction of post-operative non-surgical site infection (NSSI and length of hospital stay following hip fracture surgery. Methods: All patients admitted during a one year period with a hip fracture to our department were included in the study (n=207. Primary outcome measures were ten independent risk factors correlated to the development of non-surgical site infection following surgery for hip fracture. Secondary outcome measures were duration of hospital stay and inpatient mortality. Results: The patients who had severe cognitive impairment had a 71.0% risk of developing non-surgical site infection. Patients who had multiple medical co-morbidities also had increased risk of developing non-surgical site infection at 59.1%. Patients who developed NSSI on average stayed in hospital 13.1 days longer than patients who did not (31.6 vs. 18.5, p < .001. Conclusions: This study demonstrates the importance of reducing post-operative infection in hip fracture patients in view of reducing morbidity, mortality and cost. These patients can be stratified by risk factors and interventions can be employed in view of reducing inpatient post-operative infection rates in this cohort.

    Hip hop dance has rapidly become a popular international art form. There is limited information on injury patterns in this population. The purpose of this study was to determine injury incidence and patterns among three groups of hip hop dancers. Three hundred and twelve intermediate, advanced, and expert hip hop dancers were recruited at battles, dance conferences, clubs, and on dance related web sites within the United States and internationally. A Web-based survey was conducted over a 6-month period. Inclusion criteria included intermediate and advanced level dancers over the age of 13. Dancers were divided into three main categories: Breakers, Popper/Lockers, and New Schoolers. Separate analysis of variances were used to compare injury pattern differences between groups. Two hundred and thirty-two dancers reported a total of 738 injuries. Five hundred and six of these (sustained by 205 dancers) were time-loss (TL) injuries. Annual injury incidence was 237% (162% involving TL). Lower extremity injuries were 52% and upper extremity injuries 32% of total injuries. Breakers had a higher injury incidence compared with Popper/Lockers, and New Schoolers. Hip hop dancers report injury rates that are higher than other dance forms but similar to gymnastics. These dancers should be educated concerning injury prevention, biomechanics, and use of protective equipment. © 2010 John Wiley & Sons A/S.

    With ethical requirements to the enrollment of lower risk subjects, osteoporosis trials are underpowered to detect reduction in hip fractures. Different skeletal sites have different levels of fracture risk and response to treatment. We sought to identify fracture sites which cluster with hip fracture at higher than expected frequency; if these sites respond to treatment similarly, then a composite fracture endpoint could provide a better estimate of hip fracture reduction. Cohort study using Veterans Affairs and Medicare administrative data. Male Veterans (n=5,036,536) aged 50-99 years receiving VA primary care between 1999 and 2009 were included. Fractures were ascertained using ICD9 and CPT codes and classified by skeletal site. Pearson correlation coefficients, logistic regression and kappa statistics were used to describe the correlation between each fracture type and hip fracture within individuals, without regard to the timing of the events. 595,579 (11.8%) men suffered 1 or more fractures and 179,597 (3.6%) suffered 2 or more fractures during the time under study. Of those with one or more fractures, the rib was the most common site (29%), followed by spine (22%), hip (21%) and femur (20%). The fracture types most highly correlated with hip fracture were pelvic/acetabular (Pearson correlation coefficient 0.25, pfractures cluster with hip fractures within individuals at greater than expected frequency. If we observe similar treatment risk reductions within that cluster, subsequent trials could consider the use of a composite endpoint to better estimate hip fracture risk. Published by Elsevier Inc.

    To determine how well measures of hip geometry can predict radiological incident hip osteoarthritis (HOA) compared to well known clinical risk factors. The study population is part of the Rotterdam Study, a prospective population-based cohort. Baseline pelvic radiographs were used to measure hip geometry by two methods: Statistical Shape Models (SSM) and predefined geometry parameters (PGPs). Incident HOA (Kellgren and Lawrence (KL) ≥ 2) was assessed in 688 participants after 6.5 years without radiographic HOA at baseline. The ability to predict HOA was quantified using the area under the Receiver Operating Characteristics (ROC) curve (AUC). Comparison of the two methods showed that both contain information that is not captured by the other method. At 6.5 years follow-up 132 hips had incident HOA. Five PGPs (Wiberg angle, Neck Width (NW), Pelvic Width (PW), Hip Axis Length (HAL) and Triangular Index (TI)) and two SSM (modes 5 and 9) were significant predictors of HOA (P = 0.007). Hip geometry added 7% to the prediction obtained by clinical risk factors (AUC = 0.67 (geometry), 0.66 (gender, age, Body Mass Index (BMI)) and combining both: AUC = 0.73, respectively). Mode 12 (associated with position of the femoral head in acetabulum) and Wiberg angle were predictors of HOA in participants without radiological signs at baseline (KL = 0). Although the strength of the prediction decreased for all variables at a longer follow-up, the contribution of hip geometry was still significant (P = 0.01). Hip geometry has a moderate ability to predict HOA in participants with and without initial signs of osteoarthritis (OA), similar to and largely independent of the predictive value of clinical risk factors.

    Management of the hip capsule has been a topic of recent debate in hip arthroscopic surgery. Postoperative instability after hip arthroscopic surgery has been reported and can lead to poor outcomes. To determine the outcome of patients diagnosed with symptomatic instability after hip arthroscopic surgery at a minimum of 12 months and 24 months after revision surgery for capsular repair. Case series; Level of evidence, 4. In a cohort of approximately 1100 patients who underwent hip arthroscopic surgery, 33 patients (33 hips) developed symptomatic instability requiring a revision surgery. Two patients suffered anterior dislocations following their initial surgery. Radiographs were reviewed to evaluate for acetabular dysplasia. Three patients were lost to follow-up and 10 patients were excluded as they were arthroscopic procedure. After their index arthroscopic procedures, patients had minimal improvement at a mean of 19.1 months postoperatively on the mHHS (from 57.1 to 57.6; P = .423), HOS-Activities of Daily Living (ADL) (from 62.7 to 66.4; P = .260), and HOS-Sports (from 42.0 to 39.1; P = .800). For the patients with a minimum 1-year follow-up after revision surgery (n = 20; mean follow-up, 21.3 months), the mean mHHS (from 57.6 preoperatively to 85.8 at final follow-up; P .05). At final follow-up, all but 1 patient had improved overall physical ability levels. Revision hip arthroscopic surgery for capsular repair in patients with symptomatic instability after hip arthroscopic surgery provides good functional outcomes at a minimum of 1 and 2 years postoperatively. © 2015 The Author(s).

    Preclinical durability testing of hip replacement implants is standardised by ISO-14242-1 (2002) which is based on historical inverse dynamics analysis using data obtained from a small sample of normal healthy individuals. It has not been established whether loading cycles derived from normal healthy individuals are representative of loading cycles occurring in patients following total hip replacement. Hip joint kinematics and hip contact forces derived from multibody modelling of forces during normal walking were obtained for 15 asymptomatic total hip replacement patients and compared to 38 normal healthy individuals and to the ISO standard for pre-clinical testing. Hip kinematics in the total hip replacement patients were comparable to the ISO data and the hip contact force in the normal healthy group was also comparable to the ISO cycles. Hip contact forces derived from the asymptomatic total hip replacement patients were comparable for the first part of the stance period but exhibited 30% lower peak loads at toe-off. Although the ISO standard provides a representative kinematic cycle, the findings call into question whether the hip joint contact forces in the ISO standard are representative of those occurring in the joint following total hip replacement.

At a mean follow-up of 14 years (12-16 years), Harris hip scores showed no difference between the 2 groups. The longitudinal multilevel model analysis shows that the mean slope of the change in the Harris hip score was -0.02 for the Furlong group and -0.05 for the Charnley group; the difference is 0.03 (P = .002). The survival analysis using Kaplan-Meier regression analysis (the log-rank test lambda(2)(1) = 0.031, P = .58) does not show a significant difference between the 2 groups. Overall survival was 93.6% in the Furlong group and 94.8% in the Charnley group. 2010 Elsevier Inc. All rights reserved.

    The purpose of this study was to report the clinical results of surgical dislocation of the hip in the treatment of pre-arthritic hip disease. Between 2005 and 2010, eighty-two patients (89 hips) underwent a surgical dislocation of the hip at a mean age of 30.5 years (range 14.8-51.7); 10 females and 72 males. At a mean follow-up of 7.1 years (range 5-9.6) clinical function improved significantly. 6 patients were converted to total hip arthroplasty and 3 patients underwent an arthroscopy and an additional three patients had >1mm of joint space narrowing at latest follow-up giving us a 9-year cumulative Kaplan-Meier survivorship of 86.4% (CI, 79% to 94%). Thirty-four patients underwent internal fixation removal at a mean of 12.0 months (range 0.3-40.8 months). Although effective in the treatment of early hip disease, the surgical dislocation approach carries a high re-operation rate for removal of internal fixation; consequently, less invasive approaches should be considered for less complex deformities.

    Surgical hip dislocation (SHD) is an accepted standard to treat femoroacetabular impingement (FAI). However, arthroscopic techniques have gained widespread popularity and comparable results are reported. The purpose of this prospective comparative study was to test the hypothesis that, when compared to SHD, hip arthroscopy (HA) results in faster recovery, better short-term outcome, and equivalent morphological corrections. 38 patients presenting with clinically and morphologically verified isolated FAI were allocated to either HA or SHD. Morphological evaluation consisted of pre- and postoperative X-rays, and arthro-MRI. Demographic data, sport activities, hospital stay, complications, and the time off work were recorded. The subjective hip value, WOMAC, HHS, and hip abductor strength were measured up to 1 year. Shorter hospital stay and time off work, less pain at 3 months and 1 year, higher subjective hip values at 6 weeks and 3 months, and better WOMAC at 3 months were seen after HA. The HHS and the hip abductor strengths were higher in the HA group. However, morphological corrections at the head-neck-junction achieved by HA showed some overcorrection when compared to SHD. Labral refixation was performed less frequent in the HA group. When compared to SHD, HA results in faster recovery and better short-term outcome. However, some overcorrection of the cam deformity and limited frequency of labrum refixation with HA in this study may have a negative impact on long-term outcome.

    Mobilization with movement (MWM) has been shown to reduce pain, increase range of motion (ROM) and physical function in a range of different musculoskeletal disorders. Despite this evidence, there is a lack of studies evaluating the effects of MWM for hip osteoarthritis (OA). To determine the immediate effects of MWM on pain, ROM and functional performance in patients with hip OA. Randomized controlled trial with immediate follow-up. Forty consenting patients (mean age 78 ± 6 years; 54% female) satisfied the eligibility criteria. All participants completed the study. Two forms of MWM techniques (n = 20) or a simulated MWM (sham) (n = 20) were applied. pain recorded by numerical rating scale (NRS). hip flexion and internal rotation ROM, and physical performance (timed up and go, sit to stand, and 40 m self placed walk test) were assessed before and after the intervention. For the MWM group, pain decreased by 2 points on the NRS, hip flexion increased by 12.2°, internal rotation by 4.4°, and functional tests were also improved with clinically relevant effects following the MWM. There were no significant changes in the sham group for any outcome variable. Pain, hip flexion ROM and physical performance immediately improved after the application of MWM in elderly patients suffering hip OA. The observed immediate changes were of clinical relevance. Future studies are required to determine the long-term effects of this intervention. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Osteonecrosis of the hip (Legg-Calvé-Perthes) is a common disease, with 10,000-20,000 symptomatic cases annually in the United States. The disorder affects both adults and children and is most frequently associated with trauma and corticosteroid usage. The initial imaging evaluation of suspected hip osteonecrosis is done using radiography. MRI is the most sensitive and specific imaging modality for diagnosis of osteonecrosis of the hip. The clinical significance of hip osteonecrosis is dependent on its potential for articular collapse. The likelihood of articular collapse is significantly increased with involvement of greater than 30%-50% of the femoral head area, which is optimally evaluated by MRI, often in the sagittal plane. Contrast-enhanced MRI may be needed to detect early osteonecrosis of the hip in pediatric patients, revealing hypoperfusion. In patients with a contraindication for MRI, use of either CT or bone scintigraphy with SPECT (single-photon emission CT) are alternative radiologic methods of assessment. Imaging helps guide treatment, which may include core decompression, osteotomy, and ultimately, need for joint replacement. The ACR Appropriateness Criteria(®) are evidence-based guidelines for specific clinical conditions that are reviewed every three years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Copyright © 2016 American College of Radiology.

    Painful hip following hip dislocation or acetabular fracture can be an important signal for early degeneration and progression to osteoarthritis due to intraarticular pathology. However, there is limited literature discussing the use of arthroscopy for the treatment of painful hip. The purpose of this retrospective study was to analyze the effectiveness and benefit of arthroscopic treatment for patients with a painful hip after major trauma. From July 2003 to February 2013, we reviewed 13 patients who underwent arthroscopic treatment after acetabular fracture or hip dislocation and were followed up for a minimum of 2 postoperative years. The degree of osteoarthritis based on the Tonnis classification pre- and postoperatively at final follow-up was determined. Clinical outcomes were evaluated using visual analogue scale for pain (VAS) and modified Harris hip score (MHHS), and range of motion (ROM) of the hip pre- and postoperatively at final follow-up. There were nine male and four female patients with a mean age at surgery of 28 years (range, 20 to 50 years). The mean follow-up period of the patients was 59.8 months (range, 24 to 115 months), and the mean interval between initial trauma and arthroscopic treatment was 40.8 months (range, 1 to 144 months). At the final follow-up, VAS and MHHS improved significantly from 6.3 and 53.4 to 3.0 and 88.3, respectively (p = 0.002 and p hip flexion, abduction, adduction, external rotation, and internal rotation as minor improvements from 113.1°, 38.5°, 28.5°, 36.5°, and 22.7° to 118.5°, 39.0°, 29.2°, 38.9°, and 26.5° were observed, respectively (p = 0.070, p = 0.414, p = 0.317, p = 0.084, and p = 0.136, respectively). None of the patients exhibited progression of osteoarthritis of the hip at the final follow-up. Arthroscopic treatment after acetabular fracture or hip dislocation is effective and delays the progression of traumatic osteoarthritis.

    Full Text Available Background: Tuberculosis (TB of hip constitutes nearly 15% of all cases of osteoarticular tuberculosis. We report a retrospective study carried out on 43 children with hip TB. Materials and Methods: Forty-three children of TB hip treated between 1971 and 2000 were analysed. Twenty-four children of the early series were treated with streptomycin (S, isoniazid (H and PAS (Pa for 18 months (3HPaS, 15 HPa, while 19 children in the later series were treated with isoniazid (H, rifampicin (R and ethambutol (E or pyrazinamide (Z for 12 months [(12 RHE(Z]. Five out of 18 children with radiologically normal appearing type hip TB were treated with chemotherapy alone and 38 children were subjected to surgery; simple synovectomy alone in 31 hips, joint debridement in six hips, and proximal femoral varisation osteotomy in one. After surgery hips were immobilized in cast for one to three months according to the severity of the disease and patients pain tolerance, and then were mobilized under leg traction in bed gradually till pain subsided completely. Results: TB of hip healed with minimum sequelae in all children. In 18 Type one hip TB, normal hip (synovial form anatomy was maintained, and in 25 patients with advanced lesions some defect in the femoral head and acetabulum was noticed, though painless good hip motion was maintained. Excellent to good results were obtained in 31 children (73.1%, fair in eight (18.6%, and poor in four (9.3%. In four patients with poor results, there was some residual morphological defect in the hip. None developed ankylosis of hip. Conclusion: We achieved good outcome with minimum sequelae in this series. The management goal should be aimed not only to heal the disease but also to maintain a painless mobile hip and anatomical cephalocotyloid relationship until maturity, and retard the development of secondary osteoarthritis.

    Traumatic posterior hip dislocation in adults is generally understood to be the result of a high-energy trauma. Aside from reduced femoral antetorsion, morphologic risk factors for dislocation are unknown. We previously noticed that some hips with traumatic posterior dislocations had evidence of morphologic features of femoroacetabular impingement (FAI), therefore, we sought to evaluate that possibility more formally. We asked whether hips with a traumatic posterior hip dislocation present with (1) a cam-type deformity and/or (2) a retroverted acetabulum. We retrospectively compared the morphologic features of 53 consecutive hips (53 patients) after traumatic posterior hip dislocation with 85 normal hips (44 patients) based on AP pelvic and crosstable axial radiographs. We measured the axial and the lateral alpha angle for detection of a cam deformity and the crossover sign, ischial spine sign, posterior wall sign, retroversion index, and ratio of anterior to posterior acetabular coverage to describe the acetabular orientation. Hips with traumatic posterior traumatic dislocation were more likely to have cam deformities than were normal hips, in that the hips with dislocation had increased axial and lateral alpha angles. Hips with posterior dislocation also were more likely to be retroverted; dislocated hips had a higher prevalence of a positive crossover sign, ischial spine sign, and posterior wall sign, and they had a higher retroversion index and increased ratio of anterior to posterior acetabular coverage. Hips with posterior traumatic dislocation typically present with morphologic features of anterior FAI, including a cam-type deformity and retroverted acetabulum. An explanation for these findings could be that the early interaction between the aspherical femoral head and the prominent acetabular rim acts as a fulcrum, perhaps making these hips more susceptible to traumatic dislocation.

    The problemes of the exact preparation of the hip acetabulum for implantation of total hip prothesis have caused the development of several milling machines. Two sorts of construction predominate. Their disadvantages, especially the fact, that there is now mechanism, while is able to carry of the milled tissue, gave rise to construct a new milling machine. In cooperation with engineers of the branch mechanical engineering a new model was developed. The characteristic features are described and explained by pictures. The milling basket will be fastened on the ground plate by a quick fastener. In this way we get a hemisphere cavity, which is able to absorb all the milled tissue without any residue. A grasp will be connected with the drive shaft and guarantee an exact and rightangeled direction. The clinical tests have shown, that the new milling machine with the grasp especially is qualified for use in the osteoporotic senil bone too.

    Weak hip abductors may be related with increased hip adduction and knee abduction angular movement, which may be risk factors of lower extremity injuries. As the role of eccentric hip abduction strength (EHAS) on hip adduction angular movement and knee abduction angular movement (KABD) remains unclear, the purpose of this study was to explore the association between EHAS and hip and knee angular movement. In 100 healthy male recreational runners, EHAS was quantified using an isokinetic dynamometer, while hip and knee angular movements were collected using pressure-sensitive treadmill and Codamotion active marker system. Using multiple linear regression models (n=186 legs), no relationships between EHAS and hip and knee kinematics were found. A possible reason for the lack of relationship between EHAS and hip and knee kinematics may be owing to differences in the running kinematics. Some runners with weak EHAS may compensate the weakness by leaning toward the stance limb and thereby reduces the demand on the hip abductors with the consequence of increased knee abduction moment, which may lead to an increased knee abduction angular excursion. Possible, others mechanism as the quadriceps strength and activity in the hip and thigh muscles may also be able to explain the lack of relationship that may or may not exist. Despite the inconclusive results of this study, the findings may suggest that weak hip abductor muscles may be a relevant factor to focus on in future studies. © 2017 John Wiley & Sons A/S.

    Hip fracture registries offer an opportunity to identify and to monitor patients with rare conditions and outcomes, including hip fractures in pediatric patients. To report patient demographics and surgical outcomes of pediatric patients treated surgically for hip fractures in a large integrated health care system. Pediatric patients (fracture) with hip fractures were identified between 2009 and 2012 using our health care system's hip fracture registry. Patient characteristics, type of fracture, surgical treatment, and short-term complications. Among 39 patients identified, 31 (79.5%) were male, and the median age was 15 years old (interquartile range: 11-17 years). Most patients were Hispanic (n = 17, 43.6%) or white (n = 14, 35.9%). There were 8 patients (20.5%) with 15 comorbidities. Delbet Type IV (intertrochanteric) fractures were the most common fracture type (n = 22, 56.4%), and fixation method was equally distributed between intramedullary, screw and sideplate, and screws (n = 12, 30.8% for each). Most surgeries were performed by medium-volume surgeons (n = 22, 56.4%) at medium- and high-volume hospitals (n = 37, 94.9%). Three 90-day readmissions (7.7%), 1 infection (2.6%), 1 malunion (2.6%), and 1 revision (2.6%) were observed in this cohort during the study period. In our series using registry data, hip fractures younger than age 21 years were more common in boys and Hispanic patients. Intertrochanteric fractures (Delbet Type IV) were the most frequently observed type in our community-based hip fracture registry. Short-term complications were infrequent.

    To determine whether results of the Ortolani method of hip joint palpation in dogs were related to distraction index (DI), Norberg angle, or radiographic hip score. Cross-sectional study. 459 clinically normal dogs. Dogs were sedated for radiography and palpation of the hip joints. Results of hip joint palpation were classified as negative, mild positive, moderate positive, or severe positive. Distraction indices were measured for all dogs. Norberg angles were measured for 380 dogs for which ventrodorsal hip-extended radiographic projections were available. Hip scores assigned by the Orthopedic Foundation for Animals (OFA) were available for 95 dogs. Age, weight, and sex were not significantly associated with results of hip joint palpation. There was moderate correlation between results of hip joint palpation and DI (r = 0.636), low-moderate correlation between results of hip joint palpation and OFA hip scores (rs = 0.437), and weak negative correlation (r = -0.236) between results of hip joint palpation and Norberg angle. For joints without degenerative joint disease (DJD), there was a significant linear relationship between results of hip palpation and DI; however, for joint with DJD, there was not. Results of hip joint palpation were 5.3-fold as likely to be negative for dogs with DJD as for dogs without. Results of hip joint palpation were at best moderately correlated with radiographic measures of hip joint laxity. Therefore, hip joint palpation should be combined with hip-extended and stress radiography when assessing hip joint quality.

  17. Caudoventral hip luxation in a miniature pig

    Directory of Open Access Journals (Sweden)

    Carolina Silveira Braga

    Full Text Available ABSTRACT: A miniature pig was examined because of left pelvic limb lameness after falling from a short height. Clinical examination and radiographs of the pelvic region revealed a left caudoventral hip luxation. Surgical reduction of luxation was performed on the patient under general anesthesia using a transarticular pinning technique. Postoperative radiographs confirmed that the luxation was reduced, the joint was aligned, and the transarticular pinning was correct. The transarticular pin was removed 21 days after it was surgically inserted. The limb was fully functional in the immediate postoperative period. Nine months after the surgery, the patient could use the limb properly, but mild degenerative joint disease was observed via radiographic follow-up. This technique may be a viable treatment option for the repair of caudoventral hip luxation in miniature pigs.

    Hip problems due to dysplasia are commonly associated with female athletes in sports demanding supraphysiologic motion, such as ballet, gymnastics and figure skating. However, hip problems are rarely mentioned among wrestlers, a male sport in which flexibility is advantageous. Dysplasia may have a mostly unrecognized prevalence among wrestlers that can lead to problems and benefit from reorientation periacetabular osteotomy (PAO). Study design in this research is Level 4 evidence case reports. Three consecutive intercollegiate wrestlers ages 20, 21 and 22 years underwent PAO for dysplasia and are reported. Two underwent concomitant arthroscopy. Each returned successfully to intercollegiate wrestling at 6, 8 and 11 months. There were no complications. This work concludes that dysplasia has an unknown but mostly unrecognized prevalence among wrestlers. With proper recognition and treatment with PAO, there is a reasonable expectation that they could return to wrestling.

    Full Text Available Hip resurfacing technique is a conservative arthroplasty used in the young patient in which the femoral head is reshaped to accept metal cap with small guide stem. In the present investigation, a hybrid composite-metal resurfacing implant is proposed. The cup is made of carbon fiber/polyamide 12 (CF/PA12 covered with a thin layer of cobalt chrome (Co-Cr. Finite element (FE method was applied to analyze and compare the biomechanical performances of the hybrid hip resurfacing (HHR and the conventional Birmingham (BHR. Results of the finite element analysis showed that the composite implant leads to an increase in stresses in the cancellous bone by more than 15% than BHR, indicating a lower potential for stress shielding and bone fracture and higher potential for bone apposition with the HHR.

    2017-07-15

    Ultrasonography (US) is a useful screening method for the diagnosis of developmental dysplasia of the hip (DDH) and congenital spinal anomalies in infants. In addition, US is a useful, noninvasive imaging modality for the diagnosis of transient synovitis in children. The early detection of DDH leads to a better prognosis without surgical intervention. Moreover, spinal US allows the detection of congenital malformations and can also demonstrate normal anatomy and normal variants that may resemble disorders. Therefore, radiologists should be familiar with the sonographic anatomy of the normal infant hip, scanning and measurement techniques for DDH, the US features of transient synovitis in children, spinal US techniques, and the US features of normal anatomical structures, normal variants, and congenital spinal anomalies.

    2010-06-01

    Full Text Available Total hip arthroplasty through minimum anterior incision is a minimally invasive technique that allows access to the joint capsule without posting the skeletal muscle surrounding areas. Anterior surgical approach is advantageous because the hip joint is located closer to the front than the rear part of the limb. The surgical approach follows a internervous plane between superior and inferior gluteal nerves (in the side and femoral nerve (medially, without involving the muscle removal. This technique provides good access, through the same incision, both to the acetabul and the femur. It also allows better control of the acetabular cup, keeping the limb length, a decrease of dislocations rate and reduced post-operative precautions.

  5. Effect of Posture on Hip Angles and Moments during Gait

    Science.gov (United States)

    Lewis, Cara L.; Sahrmann, Shirley A.

    2014-01-01

    Anterior hip pain is common in young, active adults. Clinically, we have noted that patients with anterior hip pain often walk in a swayback posture, and that their pain is reduced when the posture is corrected. The purpose of this study was to investigate a potential mechanism for the reduction in pain by testing the effect of posture on movement patterns and internal moments during gait in healthy subjects. Fifteen subjects were instructed to walk while maintaining three postures: 1) natural, 2) swayback, and 3) forward flexed. Kinematic and force data were collected using a motion capture system and a force plate. Walking in the swayback posture resulted in a higher peak hip extension angle, hip flexor moment and hip flexion angular impulse compared to natural posture. In contrast, walking in a forward flexed posture resulted in a decreased hip extension angle and decreased hip flexion angular impulse. Based on these results, walking in a swayback posture may result in increased forces required of the anterior hip structures, potentially contributing to anterior hip pain. This study provides a potential biomechanical mechanism for clinical observations that posture correction in patients with hip pain is beneficial. PMID:25262565

    Summary Background Hip microinstability is an established diagnosis; however, its occurrence is still debated by many physicians. Diagnosis of hip microinstability is often challenging, due to a lack of specific signs or symptoms, and patients may remain undiagnosed for long periods. This may lead to early manifestation of degenerative joint disease. Consequently, careful patient and family history must be obtained and diagnostic imaging should follow. After a thorough clinical evaluation of the patient with suspected hip microinstability, the physician should focus on how to improve symptoms and functionality in daily and sports activities. Purpose The purpose of this review article was to give a current update regarding this diagnosis and to provide a complete diagnostic approach in order to effectively treat hip microinstability. Methods We reviewed the literature on the diagnosis, the non-operative and operative indications for the treatment of this complex and often misdiagnosed pathology. Conclusion Conservative treatment is considered the best initial approach, though, surgical intervention should be considered if symptoms persist or other hip pathology exists. Successful surgical intervention, such as hip arthroscopy, should focus on restoring the normal anatomy of the hip joint in order to regain its functionality. The role of the hip joint capsule has gained particular research interest during the last years, and its repair or reconstruction during hip arthroscopy is considered necessary in order to avoid iatrogenic hip microinstability. Various capsular closure/plication techniques have been developed towards this direction with encouraging results. Level of evidence V. PMID:28066740

    The purpose of this study was to evaluate cytokine level characteristics in the hip joint fluid, including rapidly destructive coxopathy (RDC), OA, osteonecrosis (ON) of the femoral head and RA. Thirty-three hips with RDC, 57 with OA, 36 with ON and 10 with RA were included in the study. OA hips were divided into two groups: 20 hips with early OA without joint space narrowing and 37 hips with terminal OA. ON hips were divided into three groups: 13 hips with hips with >3 mm collapse and 9 hips with terminal ON. Joint fluid was collected during surgery. Cytokine levels including IL-1β, IL-6, IL-8 and TNF-α were measured using homogeneous time-resolved fluorescence. All measured cytokine levels in RDC were significantly higher than those in OA (P 3 mm collapse were higher than those found in the ON group with hip diseases. The IL-8 level may reflect the aggressiveness of joint destruction in RDC, and IL-6 and TNF-α levels may also reflect ongoing destruction in OA and ON.

    To evaluate the possible relationship between flexible flat foot and developmental hip dysplasia in children between six and 15 years of age. Cross-sectional study including 65 patients that had undergone surgery due to residual hip dysplasia or hip dislocation and compared against 75 healthy patients. Flexible flat foot prevalence was measured in each group, with the results showing that 61% of the group with residual hip dysplasia or hip dislocation had this condition, vs. 12% in the healthy group. The statistical analysis shows that the chances of suffering from flexible flat foot, are five times greater in the hip dysplasia or hip dislocation group, than in the healthy group. There is no evidence in the literature showing a relationship between these two conditions, even though they have a common etiology. This study shows a potential measurable relation between this two conditions. Patients with hip dysplasia or dislocation may have a higher chance of presenting flexible flat foot during late childhood, adolescence and adulthood, a fact that suggests a relationship between these two pathologies. Also, patients who seek assistance for the first time because of a flexible flat foot condition without having been evaluated during the first year of life for hip dysplasia, would be better off if evaluated for residual hip dysplasia.

    Femoroacetabular Impingement (FAI) is characterized by abnormal contact of the hip joint. Many etiologies cause this painful condition, which leads to early osteoarthritis. While hip arthroscopy has become the most prevalent way to surgically correct a hip, some presentations of FAI require open surgical hip preservation techniques to fully address the pathology at hand. Certain head neck deformities may require open surgical hip dislocation utilizing a trochanteric slide osteotomy. A retroverted acetabulum may require an open periacetabular osteotomy to gain anteversion and eliminate impingement in the hip joint. Acetabular protrusio may require surgical hip dislocation with rim trimming and a possible valgus intertrochanter osteotomy. The sequelae of Legg-Calvé-Perthes disease causes complex abnormalities about the hip joint, which may require open surgery to address both the intra-articular pathology and the extra-articular pathology. Osteotomies of the proximal femur and acetabulum may all be necessary to restore a hip back to normal morphology. Chronic slipped capital femoral epiphysis (SCFE) may also require open surgical hip dislocations and complex intertrochanter osteotomies to recreate normal morphology.

    Objective To investigate the radiographic hip joint phenotype of the Pembroke Welsh Corgi. Study Design Prospective and retrospective cross-sectional study. Animals Pembroke Welsh Corgis (n = 399). Methods Ventrodorsal, hip-extended radiographs were evaluated for subluxation, osteoarthritis (OA), caudolateral curvilinear osteophytes (CCO), and circumferential femoral head osteophytes (CFHO) of PennHIP evaluated Corgis. Joint laxity was measured by distraction index (DI). Results All Corgis had DI > 0.30 (mean, 0.66), 6.8% had OA, 18% had subluxation, 22.3% had CCO, and 74.4% had CFHO. Higher DI increased the odds for subluxation and canine hip dysplasia (CHD) but not for OA, CCO, or CFHO. The presence of CCO increased the odds for OA by 4.6 times (P = .002) and 2.2 times (P = .01) for hip dysplasia. All dogs with OA had CFHO. The presence of CFHO increased the odds for subluxation by 8.7 times (p hip dysplasia. Subluxation increased the odds for OA by 15.4 times (P hip laxity that has been shown to correlate with hip OA and hip dysplasia in large-breed dogs. The relationship between CCO and OA was similar to published findings in nonchondrodystrophic large-breed dogs and the CFHO was significantly associated with subluxation. Both CCO and CFHO are associated with hip dysplasia in this small chondrodystrophic breed. PMID:23253037

    To evaluate the CT images of reduced hips after posterior hip dislocation and to propose specific diagnostic criteria based on the CT results. We retrospectively reviewed the CT findings on 18 reduced hips from 17 patients with radiographs and clinical histories of traumatic posterior hip dislocations by evaluating 18 corresponding CT scans for joint space asymmetry, intra-articular abnormalities (intra-articular fat obliteration, loose bodies, and joint effusion), changes in posterior soft tissue (capsule, muscles, and adjacent fat), the presence, and location of fractures (acetabulum and femoral head). All 18 hips (100%) showed posterior soft tissue changes. In total, 17 hips (94.4%) had intra-articular abnormalities and 15 hips (83.3%) had joint space asymmetries. In addition, 17 hips (94.4%) had fractures involving the acetabula (15 cases, 88.2%) the femoral head (13 cases, 76.5%), or on both sides (11 cases, 64.7%). The most frequent fracture location was in he posterior wall (13/15, 86.7%) of the acetabulum and in the anterior aspect (10/13, 76.9%) of the femoral head. Patients with a prior history of posterior hip dislocation showed specific CT findings after reduction, suggesting the possibility of previous posterior hip dislocations in patients.

    Dance, gymnastics, figure skating, and competitive cheerleading require a high degree of hip range of motion. Athletes who participate in these sports use their hips in a mechanically complex manner. A search of the entire PubMed database (through December 2013) and additional searches of the reference lists of pertinent articles. Systematic review. Level 3. Whether innate or acquired, dancers and gymnasts have some hypermobility that allows their hips to be placed in potentially impinging or unstable positions required for their given activity. Such extremes of motion can result in both intra-articular and extra-articular impingement as well as compensatory osseous and muscular pathology. In addition, dancers and gymnasts are susceptible to impingement-induced instability. Dancers with innate generalized hyperlaxity are at increased risk of injury because of their activities and may require longer recovery times to return to play. Both nonoperative and operative treatments (arthroscopic and open) have an important role in returning flexibility athletes to their preoperative levels of sport and dance. Because of the extreme hip motion required and the compensatory soft tissue laxity in dancers and gymnasts, these athletes may develop instability, impingement, or combinations of both. This frequently occurs in the setting of subtle pathoanatomy or in patients with normal bony anatomy. With appropriate surgical indications and the correct operative technique, the treating surgeon can anticipate high levels of return to play for the gymnast and dancer with hip pain.

    Our objectives were to clarify the 3D articular contact areas of the in vivo normal hip joint and acetabular dysplasia during specific positions using magnetic resonance imaging (MRI), voxel-based registration, and proximity mapping. Forty-two normal and 24 dysplastic hips were examined. MRI was performed at four positions: neutral; 45° flexion; 15° extension; and the Patrick position. Femur and pelvis bone models were reconstructed at the neutral position and superimposed over the images of each different position using voxel-based registration. The inferred cartilage contact and bony impingement were investigated using proximity mapping. The femoral head translated in the anterior or posteroinferior, anterosuperior, and posteroinferior direction from neutral to 45° flexion, 15° extension, and the Patrick position, respectively. Multiple regression analyses showed age, femoral head sphericity, and acetabular sphericity to be associated with higher hip instability. The present technique using subject-specific models revealed the in vivo hip joint contact area in a population of healthy individuals and dysplastic patients without radioactive exposure. These results can be used for analyzing disease progression in the dysplastic hip and pathogenesis of acetabular labral tear. Copyright © 2013 Orthopaedic Research Society.

    Symptomatic external snapping hip can be a long-standing condition affecting physical function in younger people between 15-40 years. Gluteal weakness has been suggested to be associated with the condition. The aim of this study was to investigate whether eccentric hip abduction strength....... Eccentric hip abduction strength was 16% lower in patients with external snapping hip compared with healthy matched controls (1.50 ± 0.47 Nm/kg versus 1.82 ± 0.48 Nm/kg, P = 0.01). No other strength differences were measured between patients and controls (P > 0.05). Eccentric hip abductor weakness...... were compared with 13 healthy matched controls in a cross-sectional study design. The mean age of the patients was 25.5 ± 3.4 years and the mean age of the controls was 25.6 ± 2.6 years. Eccentric and isometric strength were assessed with a handheld dynamometer, using reliable test procedures...

    The aim of this study was to assess the influence of bone mineral density and hip geometry on the fragility fracture of femoral neck and trochanteric region. There were 95 menopausal females of age ≥ 50 years with fragility fracture of hip, including 55 cases of femoral neck fracture and 40 cases of trochanteric fracture. Another 63 non-fractured females with normal bone mineral density (BMD) were chosen as control. BMD, hip axis length, neck-shaft angle and structural parameters including cross surface area, cortical thickness and buckling ratio were detected and compared. Compared with control group, the patients with femoral neck fracture or trochanteric fractures had significantly lower BMD of femoral neck, as well as lower cross surface area and cortical thickness and higher buckling ratio in femoral neck and trochanteric region. There were no significant differences of BMD and structural parameters in the femoral neck fracture group and intertrochanteric fracture group. Hip axis length and neck-shaft angle were not significantly different among three groups. The significant changes of BMD and proximal femur geometry were present in the fragility fracture of femoral neck and trochanteric region. The different types of hip fractures cannot be explained by these changes.

    Femoroacetabular impingement (FAI) is a pathomechanical process, which may cause hip pain, disability and early development of hip osteoarthritis (OA) in young and active adults. Patients with FAI experience functional disability during dynamic weight-bearing activities, which could originate from weakness of the hip muscles. The objective of this study was to compare hip muscle strength between patients with symptomatic FAI and healthy controls. It was hypothesized that patients would present overall hip muscle weakness compared to controls. A total of 22 FAI patients and 22 controls matched for gender, age, and body mass participated in the study. We evaluated isometric maximal voluntary contraction (MVC) strength of all hip muscle groups using hand-held and isokinetic dynamometry, and electromyographic (EMG) activity of the rectus femoris (RF) and tensor fasciae latae (TFL) muscles during active flexion of the hip. FAI patients had significantly lower MVC strength than controls for hip adduction (28%), flexion (26%), external rotation (18%) and abduction (11%). TFL EMG activity was significantly lower in FAI patients compared with controls (P=0.048), while RF EMG activity did not differ significantly between the two groups (P=0.056). Patients with symptomatic FAI presented muscle weakness for all hip muscle groups, except for internal rotators and extensors. Based on EMG recordings, it was demonstrated that patients with symptomatic FAI have a reduced ability to activate TFL muscle during hip flexion. These findings provide orthopedic surgeons with objective information about the amount and specificity of hip muscle weakness in patients with FAI. Future research should investigate the relationship between hip muscle weakness, functional disability and overuse injury risks, as well as the effects of hip muscle strengthening on clinical outcomes in individuals with symptomatic FAI.

    From 1965-1975 in the orthopedical Univ. Clinic Balgrist, Zurich, there were 177 reoperations after total hip prostheses necessary. In 91 replacements the interval between first and second operation was an average of 4.1 years, in 67 prosthesis-removements 2.1 years. The follow-up showed a relationship between bacteriological culture taken before and during operation and clinical results. The decision to change or remove the prostheses should be made on the positive or negative bacteriological results.

  19. Comparison of the carboxy-terminal DP-repeat region in the co-chaperones Hop and Hip.

    Functional steroid receptor complexes are assembled and maintained by an ordered pathway of interactions involving multiple components of the cellular chaperone machinery. Two of these components, Hop and Hip, serve as co-chaperones to the major heat shock proteins (Hsps), Hsp70 and Hsp90, and participate in intermediate stages of receptor assembly. In an effort to better understand the functions of Hop and Hip in the assembly process, we focused on a region of similarity located near the C-terminus of each co-chaperone. Contained within this region is a repeated sequence motif we have termed the DP repeat. Earlier mutagenesis studies implicated the DP repeat of either Hop or Hip in Hsp70 binding and in normal assembly of the co-chaperones with progesterone receptor (PR) complexes. We report here that the DP repeat lies within a protease-resistant domain that extends to or is near the C-terminus of both co-chaperones. Point mutations in the DP repeats render the C-terminal regions hypersensitive to proteolysis. In addition, a Hop DP mutant displays altered proteolytic digestion patterns, which suggest that the DP-repeat region influences the folding of other Hop domains. Although the respective DP regions of Hop and Hip share sequence and structural similarities, they are not functionally interchangeable. Moreover, a double-point mutation within the second DP-repeat unit of Hop that converts this to the sequence found in Hip disrupts Hop function; however, the corresponding mutation in Hip does not alter its function. We conclude that the DP repeats are important structural elements within a C-terminal domain, which is important for Hop and Hip function.

    A torque measurement system was added to a widely used hip wear simulator, the biaxial rocking motion device. With the rotary transducer, the frictional torque about the drive axis of the biaxial rocking motion mechanism was measured. The principle of measuring the torque about the vertical axis above the prosthetic joint, used earlier in commercial biaxial rocking motion simulators, was shown to sense only a minor part of the total frictional torque. With the present method, the total frictional torque of the prosthetic hip was measured. This was shown to consist of the torques about the vertical axis above the joint and about the leaning axis. Femoral heads made from different materials were run against conventional and crosslinked polyethylene acetabular cups in serum lubrication. Regarding the femoral head material and the type of polyethylene, there were no categorical differences in frictional torque with the exception of zirconia heads, with which the lowest values were obtained. Diamond-like carbon coating of the CoCr femoral head did not reduce friction. The friction factor was found to always decrease with increasing load. High wear could increase the frictional torque by 75%. With the present system, friction can be continuously recorded during long wear tests, so the effect of wear on friction with different prosthetic hips can be evaluated. © IMechE 2016.

    Neuropathies about the hip may be cause of chronic pain and disability. In most cases, these conditions derive from mechanical or dynamic compression of a segment of a nerve within a narrow osteofibrous tunnel, an opening in a fibrous structure, or a passageway close to a ligament or a muscle. Although the evaluation of nerve disorders primarily relies on neurological examination and electrophysiology, diagnostic imaging is currently used as a complement to help define the site and aetiology of nerve compression and exclude other disease possibly underlying the patient’ symptoms. Diagnosis of entrapment neuropathies about the hip with US and MR imaging requires an in-depth knowledge of the normal imaging anatomy and awareness of the anatomic and pathologic factors that may predispose or cause a nerve injury. Accordingly, the aim of this article is to provide a comprehensive review of hip neuropathies with an emphasis on the relevant anatomy, aetiology, clinical presentation, and their imaging appearance. The lateral femoral cutaneous neuropathy (meiralgia paresthetica), femoral neuropathy, sciatic neuropathy, obturator neuropathy, superior and inferior gluteal neuropathies and pudendal neuropathy will be discussed.

    The pattern of hip fractures, treatment, outcome of treatment, and complications of forty-four consecutive patients treated over a five-year period were retrospectively studied. This represents 3.5% of the hospitalised patients in orthopaedic services. The male:female ratio was 1:1.3. Seventy percent of the fractures occurred in those over 65 years of age. The fractures were the result of low energy trauma in 81.8% of patients. Intracapsular (cervical) fractures accounted for 79.5% of the total cases. Only two patients had associated injuries on admission. Austin Moore hemiarthroplasty was the choice of hip replacement for intracapsular fractures, while ORIF (Open reduction and internal fixation using fixed angle blade plate) was done for patients with (extracapsular) trochanteric fractures. Anaesthesia (general or regional) was uneventful. Non-fatal pulmonary embolism occurred in one patient post-hemiarthroplasty while in the hospital. This study shows that hip fractures are not uncommon in our environment although far less common than what obtains in the Caucasians.

This study intended to ascertain whether perioperative ONS is beneficial for the rehabilitation of elderly patients after hip surgery. Materials and methods: We searched databases including PubMed, Embase, and the Cochrane Central Register of Controlled Trials for articles published up to May 2014. Randomized controlled trials of ONS for elderly patients after hip surgery were included. Results: The combined trials showed that ONS had a positive effect on the serum total protein (P<0.00001 and led to a significantly decreased number of complications (P=0.0005. Furthermore, data from the infection subgroups showed significant decreases in wound infection (P=0.02, respiratory infection (P=0.04, and urinary tract infection (P=0.03. Clinical observation suggests that the intervention may improve the level of serum albumin, although the data did not reach statistical significance (P=0.48. Regarding mortality, there was no significant statistical difference between the intervention group and the control (P=0.93. Conclusion: Based on the evidence available, this meta-analysis is consistent with the hypothesis that perioperative ONS can help elderly patients recover after hip surgery and reduce complications.

    BACKGROUND & AIMS: Hip fractures are a significant cause of mortality and morbidity in the elderly. Malnutrition is a significant contributor to this, however no consensus exists as to the detection or management of this condition. We hypothesise that results of admission serum albumin and total lymphocyte count (TLC), as markers of Protein Energy Malnutrition (PEM) can help predict clinical outcome in hip fracture patients aged over 60 years. METHODS: This retrospective study evaluated the nutritional status of patients with hip fractures using albumin and TLC assays and analysed their prognostic relevance. Clinical outcome parameters studied were delay to operation, duration of in-patient stay, re-admission and in-patient, 3- and 12-month mortality. RESULTS: Four hundred and fifteen hip fracture patients were evaluated. Survival data were available for 377 patients at 12 months. In-hospital mortality for PEM patients was 9.8%, compared with 0% for patients without. Patients with PEM had a higher 12-month mortality compared to patients who had normal values of both laboratory parameters (Odds Ratio 4.6; 95% CI: 1.0-21.3). Serum albumin (Hazard Ratio 0.932, 95% CI: 0.9-1.0) and age (Hazard Ratio 1.04, 95% CI: 1.0-1.1) were found to be significant independent prognostic factors of mortality by Cox regression analysis. CONCLUSIONS: These results highlight the relevance of assessing the nutritional status of patients with hip fractures at the time of admission and emphasises the correlation between PEM and outcome in these patients.

    The diagnosis of periprosthetic infection requires a clear definition itself and structured procedure concerning anamnesis, clinical examination, laboratory findings, puncture and imaging diagnostics. The clinical presentation may vary considerable due to the time of their occurrence as early, delayed, or late infection. Recognition of risk factors and knowledge of differential diagnoses facilitate and confirm the diagnosis. The synovial fluid is assessed with regard to leukocyte count, protein content, and glucose. Intraoperative tissue specimen sampling has to be performed correctly; the histopathological and microbiological studies must be assessed using specific criteria. The examination and classification of periprosthetic membranes make discrimination of the causal pathological mechanism possible, especially distinction between septic and aseptic loosening. In this manner statements with regard to etiology and prosthesis durability are possible. Different causative microorganisms appear postoperatively at specific times. Pathogens that grow as biofilms are of great significance, as they may compound diagnosis and therapy. Early infections are often caused by virulent microorganisms (S. aureus) with acute onset. Delayed (low grade) infections are usually caused by less virulent microorganisms, such as S. epidermidis or coagulase-negative staphylococci. Many diagnostic imaging methods have been used in the assessment of periprosthetic infection: plain radiographs, arthrography, ultrasonography, computed tomography, and magnetic resonance imaging. Nuclear medicine with bone scintigraphy or positron-emission tomography enhance diagnostic capabilities. Cultures of samples obtained by sonication of prostheses are more sensitive than conventional periprosthetic tissue culture. Multiplex PCR of sonication fluid is a promising test for diagnosis of periprosthetic joint infection. The promising diagnostic accuracy for interleukin-6 and procalcitonin has yet not been

    Full Text Available Background: High rates of loosening of cemented implants led to change in technique of fixation of the implant. Methods: Fifty-nine hips were operated in 42 patients with non-cemented acetabular and cemented femoral components between January 1999 and July 2003. The average age of the patient was 45.2 years in our study. Preoperative diagnosis was avascular necrosis (28, ankylosing spondylitis (18, fracture neck femur (9, rheumatoid arthritis (2 and osteoarthritis (2. Results: At an average follow up of 3.6 years (range 1.2-5.8 years excellent to good results were obtained 92% according to Harris hip criteria. No radiological loosening was noted in any femoral or acetabular component on follow up. One poor result was seen in a case of bilateral ankylosing spondylitis operated on one side. Conclusion: Hybrid THA provides a viable and highly acceptable method of treatment of diseases of hip in young patients.

    Hip osteoarthritis results in abnormal gait mechanics, but it is not known whether abnormalities are the same in men and women. The hypothesis tested was that gait abnormalities are different in men and women with hip osteoarthritis vs. sex-specific asymptomatic groups. 150 subjects with mild through severe radiographic hip osteoarthritis and 159 asymptomatic subjects were identified from an Institutional Review Board-approved motion analysis data repository. Sagittal plane hip range of motion and peak external moments about the hip, in all three planes, averaged from normal speed walking trials, were compared for men and women, with and without hip osteoarthritis using analysis of variance. There were significant sex by group interactions for the external peak hip adduction and external rotation moments (P=0.009-0.045). Although asymptomatic women had peak adduction and external rotation moments that were respectively 12% higher and 23% lower than asymptomatic men (P=0.026-0.037), these variables did not differ between men and women with hip osteoarthritis (P≥0.684). The osteoarthritis vs. asymptomatic group difference in the peak hip adduction moment was 45% larger in women than in men. The osteoarthritis vs. asymptomatic group difference in the peak hip external rotation moment was 55% larger for men than for women (P<0.001). Sex did not influence the association between radiographic severity and gait variables. Normal sex differences in gait were not seen in hip osteoarthritis. Sex-specific adaptations may reflect different aspects of hip abductor function. Men and women with hip osteoarthritis may require different interventions to improve function.

    Bone mineral density (BMD) measurement from dual-energy X-ray absorptiometry (DXA) is widely used to assess skeletal strength in clinical practice, but DXA instruments can also measure biomechanical parameters related to skeletal shape. The objective of the study was to determine whether DXA-derived hip geometry measures provide information on fracture prediction that is independent of hip fracture probability determined from the fracture risk assessment tool (FRAX) algorithm. This was a retrospective registry study using BMD results for Manitoba, Canada. Women aged 40 years and older with baseline hip DXA, derived hip geometry measures, and FRAX scores (n = 50 420) participated in the study. Hospitalized hip fracture (n = 1020) diagnosed during 319 137 person-years of follow-up (median 6.4 y) was measured. Among the hip geometry measures, hip axis length (HAL) showed a consistent association with hip fracture risk when adjusted for age [hazard ratio (HR) 1.30 per SD increase, 95% confidence interval (CI) 1.22-1.38], and this was unaffected by further adjustment for BMD or FRAX score. Adjusted for FRAX score with BMD, there was a significant effect of increasing HAL quintile on hip fracture risk (linear trend P women (FRAX adjusted HR 1.70 per SD increase, 95% CI 1.48-1.94). DXA-derived hip geometry measurements are associated with incident hip fracture risk, but many do not confer significant independent predictive information. HAL was found to predict hip fractures when adjusted for BMD or FRAX score and may be of clinical value in refining hip fracture risk.

    The hip-joint capsule is exposed to increased tension forces during canine hip dysplasia, resulting in inflammation of the capsular tissue. It has been postulated that inflammation is associated with an increased nerve-distribution density. Therefore, it could be supposed that the nerve-distribution density in the hip-joint capsule is higher in dogs with dysplastic hip compared to healthy dogs. In 16 Labrador Retriever dogs that had been euthanised due to unrelated reasons, the hip joints were classified as normoplastic (group 1, n = 18) or dysplastic (group 2, n = 14) based on radiography. Following staining of the capsular nerve fibres by the Sihler method, histological specimens of the hip-joint capsules were scanned. By subdividing each specimen into 10 quadrants numbered from dorsomedial (Q01) to craniodorsolateral (Q10), the ratio of black to white pixels was calculated digitally for each specimen and each quadrant by using a semiautomatic image analysis. Statistical analysis was performed using an independent t-test. Comparison of the mean values of each quadrant showed a significantly higher (p hip-joint capsule in dogs with dysplastic hip could be the result of increased tension forces on this area following hip-joint dysplasia. The craniodorsal region of the hip-joint capsule is an important origin of pain and coxarthrosis in canine hip dysplasia. The results provide the pathophysiological basis for the efficacy of hip-joint denervation. Denervation of the cranial region of the acetabular rim is essential to reduce capsular inflammation and joint-related pain in canine hip dysplasia.

We hypothesized that preoperative depression impedes early functional outcome after THA (primary outcome measure. Additional objectives were perioperative changes in the psychological status and their influence on perioperative outcome. This observational study analyzed depression, anxiety, resilience, and personality traits in 50 patients after primary unilateral THA. Hip functionality was measured by means of the Harris Hip Score. Depression, state anxiety, and resilience were evaluated preoperatively as well as 1 and 5 weeks postoperatively. Trait anxiety and personality traits were measured once preoperatively. Patients with low depression and anxiety levels had significantly better outcomes with respect to early hip functionality. Resilience and personality traits did not relate to hip functionality. Depression and state anxiety levels significantly decreased within the 5-week stay in the acute and rehabilitation clinic, whereas resilience remained at the same level. Our study suggests that low depression and anxiety levels are positively related to early functionality after THA. Therefore, perioperative measurements of these factors seem to be useful to provide the best support for patients with risk factors.

    Administrative discharge registers could be a valuable and easily accessible single-sources for research data on periprosthetic hip joint infection. The aim of this study was to estimate the positive predictive value of the International Classification of Disease 10th revision (ICD-10) periprosthetic hip joint infection diagnosis code in the Danish National Patient Register. Patients were identified with an ICD-10 discharge diagnosis code of T84.5 ("Infection and inflammatory reaction due to internal joint prosthesis") in association with hip-joint associated surgical procedure codes in The Danish National Patient Register. Medical records of the identified patients (n = 283) were verified for the existence of a periprosthetic hip joint infection. Positive predictive values with 95% confidence intervals (95% CI) were calculated. A T84.5 diagnosis code irrespective of the associated surgical procedure code had a positive predictive value of 85% (95% CI: 80-89). Stratified to T84.5 in combination with an infection-specific surgical procedure code the positive predictive value increased to 86% (95% CI: 80-91), and in combination with a noninfection-specific surgical procedure code decreased to 82% (95% CI: 72-89). Misclassification must be expected and taken into consideration when using administrative discharge registers for epidemiological research on periprosthetic hip joint infection. We believe that the periprosthetic hip joint infection diagnosis code can be of use in future single-source register based studies, but preferably should be used in combination with alternate data sources to ensure higher validity.

    This study was carried out to explore articular capsule repair in first artificial hip replacement (AHR) via anterolateral approach and its influence on postoperative dislocation. A total of 292 patients who received AHR via anterolateral approach and had the articular capsule repaired in People’s Hospital of Zhengzhou (Henan, China) from February 2008 to February 2014 were selected and divided into total hip replacement (THR) group (group A1) and artificial femoral head replacement (AFHR) group (group A2). Five hundred and five cases in the control group treated using the same approach but receiving no articular capsule repair were divided into THR group (group B1) and AFHR group (group B2). Condition of postoperative dislocation was compared between the two groups. All cases were followed up for 6 months to 5 years (average: 3.75 years); it was noted that the difference in average age, gender, disease constitution and follow-up time in the two groups was not significant (P>0.05). Moreover, groups A1 and B1 were found with 1 case of early hip joint dislocation (0.73%) and 13 cases of hip joint dislocation (5.24%) respectively post-operatively, and the comparison between the two groups was statistically significant (P less than 0.05). One case of hip joint dislocation (0.65%) was found in group A2 and 5 cases (1.95%) in group B2 in early post operation and the difference between two groups had no statistical significance (P>0.05). Neither the repair group nor the control group developed late-onset dislocation after the operation. Thus, we can state that articular capsule repair is feasible during the first AHR via anterolateral approach, which decreases the occurrence of early hip joint dislocation after operation and proves that repairing articular capsule during AFHR via anterolateral approach is unnecessary.

    The increasing number of people who underwent both hip implant surgery based on World Health Organization (WHO) has received massive attention from researchers lately to develop various types of hip simulators in order to test the hip implant. Various number of hip simulator have been developed with different functions and capabilities. This paper presents the design development of biped hip simulator using SolidWorks software by taking into consideration some improvement and modifications. The finite element method is used to test the design whether it is safe to be used or not. The biped hip simulator has been successfully designed and ready to be fabricated as the endurance testing shown a positive results. The von Mises stress induced in the material is an alloy steel which is 2,975,862.3 N/m2 lower than the yield strength. Thus, the design is safe to be used as it obey the safety criterion.

    This study was conducted to examine the risk factors for recurrent dislocation after total hip arthroplasty (THA) and test the hypothesis that late dislocations are associated with recurrence. A total of 1,250 hips in 1,017 patients were retrospectively reviewed. All operations were performed through the posterolateral approach with posterior soft tissue repair. An early or late dislocation was defined as a dislocation occurring before or after one year postoperatively, respectively. Dislocation occurred in 36 hips (2.9 %) and 20 of them experienced recurrence. Recurrent dislocations were observed in ten out of 25 hips (40.0 %) with early dislocation; however, ten out of 11 hips (90.9 %) with late dislocation experienced recurrence (p = 0.0046). Multivariate analysis revealed that late dislocation was significantly associated with recurrence with odds ratio of 5.94 per year. Seven in 20 hips with recurrent dislocation required surgical treatment. Late dislocation significantly contributed to the development of recurrent dislocations.

    Full Text Available Abstract Hip pathology may cause groin pain, referred thigh or knee pain, refusal to bear weight or altered gait in the absence of pain. A young child with an irritable hip poses a diagnostic challenge. Transient synovitis, one of the most common causes of hip pain in children, must be differentiated from septic arthritis. Hip pain may be caused by conditions unique to the growing pediatric skeleton including Perthes disease, slipped capital femoral epiphysis and apophyseal avulsion fractures of the pelvis. Hip pain may also be referred from low back or pelvic pathology. Evaluation and management requires a thorough history and physical exam, and understanding of the pediatric skeleton. This article will review common causes of hip and pelvic musculoskeletal pain in the pediatric population.

  6. On the matter of synovial fluid lubrication: implications for Metal-on-Metal hip tribology.

    Myant, Connor; Cann, Philippa

    2014-06-01

    Artificial articular joints present an interesting, and difficult, tribological problem. These bearing contacts undergo complex transient loading and multi axes kinematic cycles, over extremely long periods of time (>10 years). Despite extensive research, wear of the bearing surfaces, particularly metal-metal hips, remains a major problem. Comparatively little is known about the prevailing lubrication mechanism in artificial joints which is a serious gap in our knowledge as this determines film formation and hence wear. In this paper we review the accepted lubrication models for artificial hips and present a new concept to explain film formation with synovial fluid. This model, recently proposed by the authors, suggests that interfacial film formation is determined by rheological changes local to the contact and is driven by aggregation of synovial fluid proteins. The implications of this new mechanism for the tribological performance of new implant designs and the effect of patient synovial fluid properties are discussed. Copyright © 2014 Elsevier Ltd.

    2014-02-01

    Proposed benefits of total hip resurfacing arthroplasty over total hip arthroplasty (THA) include better proprioception, but this has not been rigorously tested or validated. Our purpose was to apply an advanced testing device that objectively quantifies dynamic postural stability to determine if total hip resurfacing is associated with improved proprioception compared with standard or large-head THA. Three groups of 25 patients (total hip resurfacing, THA femoral head > 32 mm, THA femoral head ≤ 32 mm) and a matched control group were recruited. All participants had UCLA scores ≥ 5 and Harris hip scores ≥ 90 at the time of testing. Testing was conducted using a commercially available device that uses a multidirectional, powered platform to measure deviations of the center of mass and consisted of trials with both double- and single-limb support. Double-limb testing showed no differences between groups. In single-limb testing, the operative side performed better in patients who had undergone total hip resurfacing versus THA, but this difference disappeared when the operative side was normalized to the nonoperative side. When compared with control subjects who had not had arthroplasty, both operative and nonoperative sides showed significantly worse proprioception for all arthroplasty cohorts, suggesting that decreased proprioception is associated with arthritis of the hip in young adults. Total hip resurfacing arthroplasty did not result in improved proprioception compared with THA. These results tend to refute the concept that improved proprioception is a rationale for selecting total hip resurfacing over THA in young patients.

    Full Text Available Abstract Background Hip dislocation in children with cerebral palsy (CP is a common and severe problem. The dislocation can be avoided, by screening and preventive treatment of children with hips at risk. The aim of this study was to analyse the characteristics of children with CP who develop hip displacement, in order to optimise a hip surveillance programme. Methods In a total population of children with CP a standardised clinical and radiological follow-up of the hips was carried out as a part of a hip prevention programme. The present study is based on 212 children followed until 9–16 years of age. Results Of the 212 children, 38 (18% developed displacement with Migration Percentage (MP >40% and further 19 (9% MP between 33 and 39%. Mean age at first registration of hip displacement was 4 years, but some hips showed MP > 40% already at two years of age. The passive range of hip motion at the time of first registration of hip displacement did not differ significantly from the findings in hips without displacement. The risk of hip displacement varied according to CP-subtype, from 0% in children with pure ataxia to 79% in children with spastic tetraplegia. The risk of displacement (MP > 40% was directly related to the level of gross motor function, classified according to the gross motor function classification system, GMFCS, from 0% in children in GMFCS level I to 64% in GMFCS level V. Conclusion Hip displacement in CP often occurs already at 2–3 years of age. Range of motion is a poor indicator of hips at risk. Thus early identification and early radiographic examination of children at risk is of great importance. The risk of hip displacement varies according to both CP-subtype and GMFCS. It is sometimes not possible to determine subtype before 4 years of age, and at present several definitions and classification systems are used. GMFCS is valid and reliable from 2 years of age, and it is internationally accepted. We recommend a hip

She was treated with closed reduction and immobilisation in skin traction for three weeks. She was followed up closely for one year and did not develop any complications during that period.

  13. The role of arthroscopic thermal capsulorrhaphy in the hip.

    Philippon, M J

    2001-10-01

    Arthroscopic thermal modification of collagen in the hip capsular tissue appears to be a treatment option for patients with hip instability. Traumatic hip instability is associated with frank dislocation or a subluxation, and labral tears. Atraumatic hip instability is associated with evidence of generalized ligament laxity. It can be associated with bone-collagen type disorders, including Ehlers-Danlos syndrome, Down syndrome, arthrochalasis multiplex congenita, developmental dysplastic hip, and idiopathic type. As previously discussed by Bellabarba et al, capsular laxity may be the underlying cause of dynamic hip instability. The capsule is a fibrous, thick, and strong structure that encircles the proximal femur and the acetabulum. The capsule is thicker anteriorly than posteriorly, and consists of two sets of fibers, circular and longitudinal. The capsule ligaments play a very important role in hip stability. The hip joint capsule is reinforced by the iliofemoral, pubofemoral, and ischiofemoral ligaments. It remains sensitive to stretch and serves as a mechanism for muscular feedback and pain. The iliofemoral ligament limits hyperextension and lateral rotation of the hip joint and is taut in full extension. Full extension of the hip exposes the capsule and ligaments to a twisting and shortening effect that forces the head onto the acetabulum. We are currently studying the effect of iliofemoral ligament deficiency and its relationship to instability. Many of the properties of synovial lubrication depend on contact with articular surfaces, and incongruency due to instability may have some functional role in distribution of synovial fluid, leading to stresses from weightbearing and eventually to rapid deterioration of the articular surfaces. The high-level athletes in this series include two professional baseball players, three professional golfers (PGA), one professional football player (NFL), one figure skater (Olympic gold medalist), one gymnast (Olympic level

    Full Text Available Prasad Antapur, Nizar Mahomed, Rajiv GandhiToronto Western Hospital, Toronto, Ontario, CanadaAbstract: As the world’s population ages, hip fractures pose a significant health care problem. Hip fractures in the elderly are associated with impaired mobility, and increased morbidity and mortality. Associated conditions, such as osteoporosis, medical comorbidity, and dementia, pose a significant concern and determine optimal treatment. One-year mortality rates currently range from 14% to 36%, and care for these patients represents a major global economic burden. The incidence of hip fractures is bimodal in its distribution. Young adult hip fractures are the result of high energy trauma, and the larger peak seen in the elderly population is secondary to low-energy injuries. The predilection for the site of fracture at the neck of femur falls into two major subgroups. Pertrochanteric fractures occur when the injury is extracapsular and the blood supply to the head of femur is unaffected. The management of this group involves internal fixation through a sliding hip screw device or intramedullary fixation device, both of which have good results. The other group of patients who sustain an intracapsular fracture at the femoral neck are at increased risk of nonunion and osteonecrosis. Recent papers in the literature have shown better functional outcomes with a primary hip replacement over other treatment modalities. This article reviews the current literature and indications for a primary total hip replacement in these patients.Keywords: hip fractures, elderly, hip replacement

    Dancers frequently present with hip pain. The etiology of this pathology has not been clearly identified from an anatomical perspective. Structural variations including hip dysplasia and dynamic variables from the foot to the pelvis will be discussed. Understanding the etiology as a structural entity, neuromuscular entity or a combination of the two, allows for a successful rehabilitative process and a successful return to dance. This article describes the possible correlation between hip dysplasia and hip pain in the dancer, the relationship of dance postures to the kinematic chain and outlines possible treatment strategies for management.

    The best approach to use when performing THA is controversial. We did a prospective, nonrandomized multicenter study of 1089 THAs to evaluate patient-centered hip scores and dislocation and revision rates when comparing anterolateral and posterior hip approaches at 5 years' followup. Patients were divided into two groups depending on which surgical approach was used: anterolateral or posterior. The primary outcome measure was change in Oxford hip score. At 5 years, there were no differences in change in Oxford hip score and in dislocation or revision rates between the groups. Level II, therapeutic study.

    Hip dysplasia is a common developmental disorder of the dog, consisting of varying degrees of hip laxity, progressive remodeling of the structures of the hip, and subsequent development of osteoarthritis. It is a juvenile-onset condition, with clinical signs often first evident at 4 to 12 months of age. A tentative diagnosis of hip dysplasia can be made based on signalment, history, and physical examination findings. The Ortolani test is a valuable tool for identifying juvenile dogs affected with this condition. Further diagnostics can then be prioritized, contributing to prompt diagnosis and appropriate treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

    This study examined the clinical outcome of 220 hips in 196 Asian patients who underwent primary total hip arthroplasty (THA) for treatment of developmental dysplasia of the hip (DDH) using a modified S-ROM modular (S-ROM-A) stem designed for Asians, after 2-5 years (mean, 3.3 years) of follow-up. The stem was placed so that the anteversion angle of the neck was decreased against the sleeve in 56% of the hips and increased in 18% of the hips. Bone ingrown fixation was achieved in 99.5% of the hips on X-ray at final follow-up. There were 2 (0.9%) dislocations postoperatively. In primary THA for treatment of DDH accompanied by femoral rotational deformity, the freely-rotatable modular stem provided favorable short-term outcomes by affording both morphological and functional advantages.

    Full Text Available There is a need of independent prospective studies about modern generation of hip resurfacing implants. The aim of this propective observational study was to compare the functional outcomes and revision rates with hip resurfacing arthroplasty and total hip arthroplasty and to present the preliminary results at 2 years. Patients included were recruited prospectively in the Partial Pelvic Replacement Hip Project by a single surgeon between January 2007 and January 2010. Patients were assessed with the Harris Hip Score (HHS and Postel-Merle d’Aubigné (MDA score and Devane Score. The end point of the study was reoperation for any cause related to the prosthesis. At a mean follow up of 38.6 months there were a total of 142 patients with hip resurfacing (group 1 [100 Durom® (Zimmer Inc., Warsaw, IN, USA and 42 Birmingham Hip Resurfacing® (Smith & Nephew, Memphis, TN, USA] and 278 patients with total hip arthroplasty (group 2. The results showed significantly greater gain of HHS, MDA and Devane score with hip resurfacing procedures. However, considering all the complications, the rate was significantly higher in group 16.4% vs 1.79% in group 2 (P<0.0001. In group 1 we observed 6 complications only concerned males with Durom® implants. The follow up of this cohort is still on going and may deliver more information on the evolution of these results in time.

    The implantation of a bipolar partial hip endoprosthesis is a treatment of choice for displaced medial femoral neck fracture. We present an experimental study which asses and compare biomechanical and clinical status through period before and after hip fracture and implantation of bipolar partial hip endoprosthesis. This study encompassed 75 patients who suffered from an acute medial femoral neck fracture and were treated with the implantation of a bipolar partial hip endoprosthesis. Their biomechanical status (stress distribution on the hip joint weight bearing area) and clinical status (Harris Hip Score) were estimated for the time prior to the injury and assessed at the follow-up examination that was, on average, carried out 40 months after the operation. Despite ageing, the observed Harris Hip Score at the follow-up examination was higher than that estimated prior to the injury (77.9 > 69.6; p = 0.006). Similarly, the hip stress distribution was reduced (2.7 MPa endoprosthesis for patients with displaced medial femoral neck fractures improves the biomechanical and clinical features of the hip, what should have on mind during making decision about treatment.

    Early identification and intervention with conservative measures is important to help manage hip dysplasia in children with a high adductor and iliopsoas tone and delay in weight bearing. The effect of a daily standing program with hip abduction on hip acetabular development in ambulatory children with cerebral palsy was studied. The participants were 26 children with spastic diplegia cerebral palsy (CP), classified at Level III according to the Gross Motor Function Classification System (GMFCS). Thirteen children stood with hip abduction at least 1 h daily from 12 to 14 months of age to 5 years with an individually fabricated standing frame with hip abduction. At the age of 5 years, radiologic results of the study group were compared with a comparison group of 13 children with spastic diplegia CP who had not taken part in a standing program. The migration percentage in all children who stood with abduction remained within stable limits (13-23%) at 5 years of age, in comparison to children who did not stand in abduction (12-47%) (p diplegia CP. Abnormal acetabular development is a problem related to mobility problems and spasticity muscles around the hip. The literature suggests that postural management and standing programs could reduce levels of hip subluxation and increase function in children with cerebral palsy. A standing program with hip abduction can be a beneficial to develop more stable hips in children with spastic diplegic GMFCS level III.

    Patients with Charcot-Marie-Tooth disease may develop hip dysplasia. Hip geometry in these patients has not been well described in the literature. We compared the hip morphometry in Charcot-Marie-Tooth hip dysplasia (CMTHD) and developmental dysplasia of the hip (DDH) in terms of extent of (1) acetabular dysplasia and subluxation, (2) acetabular anteversion and osseous support, (3) coxa valga and femoral version, and (4) osteoarthritis. Fourteen patients with CMTHD (19 hips; mean age, 23 years) presenting for periacetabular osteotomy were matched to 45 patients with DDH (45 hips; mean age, 21 years) based on age, sex, and BMI. We assessed acetabular dysplasia and subluxation using lateral center-edge angle (LCEA), anterior center-edge angle (ACEA), and acetabular roof angle of Tönnis (TA) on plain pelvic radiographs and acetabular volume, area of femoral head covered by acetabulum, and percentage of femoral head covered by acetabulum on three-dimensional CT reconstruction models. Acetabular version and bony support, femoral version, and neck-shaft angle were measured on two-dimensional axial CT scans. Hip osteoarthritis was graded radiographically according to Tönnis criteria. Acetabular dysplasia was more severe in CMTHD, as measured by smaller LCEA (p coxa valga (p coxa valga, and hip osteoarthritis was more severe in CMTHD. These findings are important in choosing the appropriate surgical strategy for patients affected by CMTHD.

At follow-up, significantly fewer patients had heterotopic ossifications in the tenoxicam groups than in the placebo and morphine groups. There was no significant difference between the 2 tenoxicam-treated groups, and we therefore conclude...... that tenoxicam 20 mg for 5 days postoperatively can reduce heterotopic ossification after cemented total hip arthroplasty....

    Joint mobilization and manipulation stimulate mechanoreceptors, which may influence the joint and surrounding muscles. The purpose of this pilot study was to determine the effect of grade IV inferior hip joint mobilization on hip abductor torque. Thirty healthy subjects were randomly assigned to a control group (grade I inferior hip joint mobilization) or an experimental group (grade IV inferior hip joint mobilization). Subjects performed a pre- and post-intervention test of five isometric repetitions on the Cybex Normö dynamometer; the average torque was determined for both pre- and post-intervention measurements. These data were analyzed using the independent samples t-test with the significance level set at Phip abductor torque in the experimental group (P=0.03). The experimental group demonstrated a 17.35% increase in average torque whereas the control group demonstrated a 3.68% decrease in average torque. These findings are consistent with other studies demonstrating that the use of grade IV non-thrust mobilization improves strength immediately post-intervention in healthy individuals. The results of this pilot study provide physical therapists with further support for the utilization of manual therapy in conjunction with therapeutic exercise to enhance muscle strength.

    Transient osteoporosis of the hip (TOH) presents with acute onset pain and bone marrow edema (BMe) on MR imaging. The purpose of this study is to revise the MR imaging characteristics of TOH by analyzing the data derived from 155 hip examinations. We also sought to explore the relationship between the duration of symptoms and the presence of sparing and subchondral fractures. MR images of 155 hips (141 TOH patients) were retrospectively evaluated for the presence of insufficiency fractures and the morphology of BMe. Sparing of the medial bone marrow of the femoral head was recorded together with demographic and clinical data. Progression to regional migratory osteoporosis (RMO) and postpartum cases were also recorded. Our population consisted of 76.4% male and 23.6% female patients. RMO progression was recorded in 19.4% and 4 postpartum cases displayed bilateral disease. Sparing of the medial bone marrow was present at 87.7% of patients and disappeared as the disease progressed (P=0.005). BMe was restricted within the femoral head in 11.0%, extended to the femoral neck in 40% and to the femoral shaft in 49% of the cases studied. Subchondral fractures were present at 48.7% of the hips. This study describes TOH patient characteristics, the MR imaging findings (BMe pattern, microfractures), their association with symptom duration and the chance of progressing to RMO.

    Full Text Available Background: Transient osteoporosis of the hip (TOH is a poorly understood and forgotten clinical entity. The diagnosis is often delayed, and inappropriate treatment is provided, due to the lack of its awareness among the clinicians. Materials and Methods: Twelve patients (11 male and one female within the age group of 35–50 years, were identified retrospectively from the hospital records between July 2011 and June 2015 who had evidence of TOH on clinical and radiological parameters. Results: All the patients were treated conservatively by nonweight bearing mobilization, anti-inflammatory drugs, bisphosphonates, calcium, and Vitamin D supplements. None of our patients had any symptoms after 6 months of conservative management. The disease did not progress, and there was no evidence of hip joint involvement in any of the cases. Plain radiographs were not diagnostic in the early detection of TOH. Magnetic resonance imaging was found to be highly specific and sensitive in diagnosing TOH. The clinical condition of TOH is characterized by its acute onset of hip pain in middle-aged people, and its symptoms are out of proportion to the radiological findings. Conclusion: The TOH is a nondestructive and self-limiting condition of the hip, which responds well to the conservative treatment. We believe that TOH could be a subset of complex regional pain syndrome type 1, as it has many similarities in clinical presentation and management. Awareness of this entity is important to the clinicians for an early diagnosis and to avoid unnecessary treatment for other mimicking conditions.

    To determine the frequency of disease, and to evaluate the methods used for lumbar spine radiography in Korea. Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1215 patients, taken using 14x17 inch film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. In 15 patients (1.2%), the radiographs revealed hip or pelvic lesion, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesion in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 or the 20 hospitals which responded, 14{sup x}17{sup f}ilm was being used for lumbar radiography, while in the other nine, film size was smaller. Plain radiography of the lumbar spine including both hip joints, may be a useful way to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis.

    The objective of this study was to evaluate patients' braking performance using a modern driving simulator after undergoing a right hip arthroscopy. This prospective study included 5 total driving sessions at which measurements were taken. The study was conducted at an academic medical center. A total of 14 patients scheduled to undergo a right hip arthroscopy were enrolled and compared with a control group of 17 participants to account for a potential learning phenomenon. Patients drove in the simulator preoperatively to establish a baseline, and then drove again at 2, 4, 6, and 8 weeks postoperatively. The control group did not undergo any type of surgical procedure. The main independent variable was time from surgery. A modern driving simulator was used to measure initial reaction time (IRT), throttle release time (TRT), foot movement time (FMT), and brake travel time (BTT). The braking reaction time (BRT) was calculated as the sum of IRT + TRT + FMT, and the total braking time (TBT) was calculated as the sum of BRT + BTT. The experimental group showed no significant changes in BTT (P = 0.11, ηG = 0.04) nor TBT (P = 0.20, ηG = 0.03) over the duration of 8 weeks. Although the experimental group did exhibit significant improvements in IRT (P = 0.002), TRT (P < 0.0001), FMT (P < 0.0001), and BRT (P = 0.0002) between preoperative and 2 weeks postoperative driving sessions, there were no significant changes thereafter. The mean preoperative TBT and 2 weeks postoperative TBT for the experimental group were 3.07 seconds (SD = 0.50) and 2.97 seconds (SD = 0.57), respectively. No learning phenomenon was observed in the control group. This study's findings suggest that patients may return to driving 2 weeks postoperatively from a right-sided hip arthroscopy procedure.

  14. CUSTOMIZED ACETABULAR COMPONENTS IN REVISION HIP ARTHROPLASTY

    Directory of Open Access Journals (Sweden)

    G. M. Kavalersky

    2016-01-01

    Full Text Available In recent years, there is a trend of increasing demand for revision hip arthroplasty. Among these patients there are many with complex acetabular defects, including patients with pelvic discontinuity. To ensure stability for revised acetabular components in such cases becomes a challenging or unachievable task. Such defects give indications for printing customized tri-flange acetabular component. The authors analysed own experience of creating and applying custom made acetabular components in 3 patients with complex acetabular defects. Material and methods. Among the patients there were 2 women and 1 man. Average age was 60,3±19,4 years (38 to 78 years. Two patients had III B defects with pelvic discontinuity and one patient had III A defect by Paprosky classification. As the first step, the authors in collaboration with engineers printed a plaster full size pelvic 3D model, as the second step a customized tri-flange acetabular component was designed and printed. Harris Hip Score was evaluated preoperatively and 3 months postoperatively. Results. Average follow-up period was 5,3±2,5 months (3 to 8 months. The authors observed no cases of implant loosening, dislocation or deep periprosthetic infection. Average Harris Hip Score before surgery was 27,13 and after surgery – 74,1 indicating a significant improvement in 3 months postoperatively. Conclusion. Indications for use of individual acetabular components in reported patients correspond to indications formulated by Berasi et al. The authors obtained encouraging early follow-up outcomes that correspond to data of other authors. In one patient certain difficulties were reported due to insufficient pelvic distraction. Component’s flanges prevented achieving adequate pelvic distraction. Nevertheless, good primary stability was achieved. Modern software and 3D metal printers can significantly reduce the production cost of customized acetabular components. Application of this technology can be

    Injury data on hip and groin injuries vary, and these injuries are often misrepresented or overlooked for more commonly seen injuries, such as those to the foot and ankle. To provide a systematic review of the injury rates of hip and groin pathology in dancers and look to establish a better understanding of the occurrence of hip and groin injuries in the dancer population. A literature search was performed using PubMed and CINAHL databases for articles published between 2000 and 2016. Inclusion criteria consisted of (1) documentation of the number of hip and/or groin injuries, (2) study population consisting of dancers whose training included some level of ballet, and (3) studies of levels 1 through 3 evidence. Systematic review. Level 3. A single reviewer identified studies that met the inclusion criteria. The number of overall injuries, hip/groin injuries, study participants, injured participants, training hours per week, mean age of study group, injury definition, injury reporting method, and study time frame were extracted. Thirteen unique studies were included in the descriptive analysis. Of the 2001 dancers included in this study, 3527 musculoskeletal injuries were seen in 1553 dancers. Of these, 345 injuries were localized to the hip and groin region (overall rate, 17.2%). An incidence rate of 0.09 hip and groin injuries per 1000 dance-hours was seen in the selected cohort studies. Of 462 professional dancers, 128 hip/groin injuries were recorded, for an injury rate of 27.7%. Of the 1539 student dancers, 217 hip/groin injuries were recorded, for an injury rate of 14.1% ( P hip and groin injuries have many limitations. However, these injuries represent an important health issue for dancers of all skill levels, encompassing 17.2% of musculoskeletal injuries seen in dancers. An increasing rate of hip/groin injuries is seen in professional dancers compared with students.

    Full Text Available This article is about two patients having vascular injuries complicating total hip arthroplasty because of intraoperative indirect injuries. One patient had a delayed presentation of acute lower limb ischaemia, in which he required amputation of his left second toe because of ischaemic gangrene. The other patient had acute lower limb ischaemia leading to permanent muscle and nerve damage because of delayed recognition. Both patients had vascular interventions for the indirect vascular injuries. Preoperative workup for suspicious underlying peripheral vascular disease, intraoperative precautions, and perioperative period of vascular status monitoring are essential for prevention and early detection of such sinister events.

    Minimally invasive surgery has been developed to reduce incision length, muscle damage, and rehabilitation time. However, reduced exposure of anatomical landmarks may result in technical errors and inferior implant survivorship. The objective of this study was to compare in vivo motions and hip joint contact forces during gait in total hip arthroplasty subjects, performed with either minimally invasive surgery or standard surgical approaches. Fifteen subjects implanted using either minimally invasive surgery anterolateral, minimally invasive surgery posterolateral, or traditional posterolateral total hip arthroplasty were evaluated using fluoroscopy while performing gait on a treadmill. Kinematics, obtained using 3D-to-2D image registration technique, were input as temporal functions in a 3D inverse dynamic mathematical model that determines in vivo soft tissue and hip contact forces. The subjects implanted with posterolateral and anterolateral minimally invasive surgery demonstrated significantly less separation than those implanted with the traditional approach (P<0.01). The minimally invasive surgery subjects also experienced lower average maximum peak forces, with 3.2 body weight for the anterolateral minimally invasive surgery and 2.9 body weight for the posterolateral minimally invasive surgery subjects, compared to 3.5 body weight for the traditional subjects (P=0.02 and P=0.03, respectively). This is the first study to compare in vivo weight-bearing kinematics, separation and kinetics for traditional, anterolateral minimally invasive surgery and posterolateral minimally invasive surgery total hip arthroplasty subject groups. Our data indicated in all analyzed parameters differences between the minimally invasive surgery and the traditional groups, with favorable results for the minimally invasive surgery subjects. This may be related, to a reduction in stabilizing soft tissues after a minimally invasive surgery procedure, leading to lower bearing surface

    To compare radiographic and arthroscopic abnormalities in juvenile dogs with clinically apparent hip dysplasia. Case series. 52 dogs (70 hip joints) with clinical signs of hip dysplasia scheduled to undergo triple pelvic osteotomy. A ventrodorsal radiographic projection of the pelvis was evaluated by a radiologist unaware of clinical and arthroscopic findings, and radiographic osteoarthritic abnormalities were judged and scored as absent (0), mild (1), moderate (2), or severe (3). Arthroscopy was performed by a surgeon unaware of clinical and radiographic findings, and arthroscopic abnormalities were graded from 0 (normal) to 5 (exposed, eburnated subchondral bone). In 30 of the 70 (43%) hip joints, no radiographic osteoarthritic abnormalities were seen. Severe, full-thickness articular cartilage lesions (grade 4) of the femoral head or acetabulum were seen arthroscopically in 14 (20%) joints. Lesions > or = grade 2 were seen in 60 (86%) joints. Partial tearing of the ligament of the femoral head was present in 57 (81%) joints, and complete rupture was seen in 5 (7%). Radiographic abnormalities were seen in 13 of the 14 (93%; 95% confidence interval, 66% to 99.8%) joints with grade 4 arthroscopic abnormalities but in only 23 of the 46 (50%; 95% confidence interval, 35% to 65%) joints with grade 2 or 3 arthroscopic abnormalities. Results suggest that radiography is not a sensitive method for identifying moderate cartilage lesions in juvenile dogs with hip dysplasia. If moderate cartilage lesions are an important prognostic indicator for the success of triple pelvic osteotomy, then methods other than radiography should be used to detect these lesions.

    The high hip center technique used for a deficient acetabulum is reconstruction of the hip at a high center of rotation. In the literature, there is no consensus regarding the value of this technique. We investigated whether the new-generation biconical threaded Zweymüller cup fixed in a high nonanatomic position in patients with arthritis secondary to congenital hip disease experienced different rates of polyethylene wear and long-term survivorship when compared with anatomically positioned cups. We studied the polyethylene wear rate and Kaplan-Meier survivorship of 104 titanium threaded Zweymüller cups in 88 patients (81 females), placed in 70 hips at near-normal hip center and in 34 hips at a high hip center position at a distance of 31.1 to 60 mm (mean, 39.7 mm) from the interteardrop line. Minimum followup was 2 years (mean +/- SD, 8.6 +/- 3.5 years; range, 2-15 years). The mean linear polyethylene wear rates in the near-normal and high hip center groups were not different (0.110 +/- 0.050 mm and 0.113 +/- 0.057 mm, respectively). The Kaplan-Meier 15-year cup survivorship rates with revision for any reason as an event of interest in the near-normal and high hip center groups also were not different (97.2% [95% confidence interval, 88.5%-99.3%] and 97.1% [95% confidence interval, 73.8%-99.3%], respectively). The high hip center technique using a biconical threaded Zweymüller cup in patients with arthritis secondary to congenital hip disease results in a polyethylene wear rate and long-term cup survivorship comparable to those observed in anatomically positioned cups. Level III, therapeutic study. See the Guidelines for Authors for a complete description of level of evidence.

    Full Text Available Septic arthritis of the hip in children has multiple sequelae and may result in severe disability. Significant morbidity can be prevented by early recognition and treatment. The authors reviewed 13 children with 14 hips with sequelae of septic arthritis of the hip. All of children had history of hip septic arthritis before age of 4 years. Six were male subjects, and 7 were female subjects. We evaluated the history, clinical findings and radiographs of all children who had been treated at the Imam Khomeini hospital between 1986 and 2001 for septic arthritis of the hip. Final results of operations in patients include range of motion, presence or absence pain, joint stability, limb-length discrepancy were assessed. Three hips had mild pain in usual daily activities and one patient with cerebral palsy experienced hip instability. Most of patients (80% had flexion contracture about 10-15 degrees .Final results showed average limb length discrepancy was about 2.8 cm. Septic arthritis of the hip in children may result in a spectrum of residual problems and the significant complications can be averted by early detection and treatment. Treatment in younger age cause better outcome.

  6. Paralytic dislocations of the hip in adolescence: Orthopaedic treatment

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Paralytic dislocation of the hip in adolescence is not typical, but presents a serious problem whether diagnosed primarily in adolescence or due to the lack of treatment or failed treatment in earlier age. It is characteristic of cerebral palsy and myelomeningocele. If the paralytic dislocation of the hip in adolescence is asymmetric, then pelvic obliquity, leg-length discrepancy, imbalance in sitting position, scoliosis and secondary spondylosis with all its consequences ensue. Complications like hip pains due to secondary arthrosis and walking ability impairment are frequent in ambulatory patients. The dislocation is the result of muscle imbalances in the hip region. The diagnosis is based on Illness history, clinical examination, neurological examination and radiography. Treatment is mostly operative, except in cases of pelvic symmetry and absence of difficulties. Pelvic and/or femoral osteotomy with or without open reduction of the hip is done in ambulatory patients with cerebral palsy. Soft-tissue surgery, hip flexors release and tenotomy of the hip adductors, are done in non-ambulatory patients with cerebral palsy. In patients with myelomeningocele soft-tissue surgery, hip flexors release and tractus iliotibialis resection on the lower side of the pelvis, are done regardless of the ability to walk. The same bone surgery procedures as in cerebral palsy are done only in ambulatory patients with unilateral dislocations if soft-tissue surgery failed.

    2018-02-20

    Osteoporotic hip fractures can be life changing and can increase mortality. Treatment of osteoporosis following hip fracture is often delayed. We began offering osteoporosis medication during hospitalization for hip fracture, dramatically increasing the number of patients meeting standard of care. Osteoporotic hip fracture is a debilitating condition with major morbidity and mortality implications. Osteoporosis medication given within 90 days of hip fracture improves mortality and reduces risk of future fractures. The aim of this project was to improve rates of timely osteoporosis treatment following fragility hip fracture. This was a two-step intervention utilizing the Plan-Do-Study-Act cycle, beginning with resident-focused education in cycle 1. In cycle 2, we offered osteoporosis medication to inpatients for hip fracture with help from a new electronic order set. Prior to this intervention, 32% of patients received osteoporosis medication within 90 days of fragility hip fracture; this improved to 81% after intervention. Resident education and an electronic order set dramatically improved the percentage of patients meeting standard of care with osteoporosis pharmacotherapy following fragility fracture.

    2009-12-01

    SUMMARY: Data of 17 male patients with a final diagnosis of transient osteoporosis (TO) of the hip seen at the radiology department of a university hospital over a period of 7 years were retrospectively studied. Comparison of the proportion of doctors among TO cases with that among other hip joint pathologies revealed a significant difference. PURPOSE: The objective of this study is to present clinical and radiological findings of hip TO and to assess the association of the condition with patients' occupation. MATERIALS AND METHODS: Data of 17 male patients with a final diagnosis of transient osteoporosis of the hip seen at the radiology department of a university hospital over a period of 7 years were retrospectively studied. RESULTS: The diagnosis of transient hip osteoporosis was in accordance with the published literature for clinical, imaging findings, and laboratory results. Among the 17 cases of male transient hip osteoporosis, 65% were physicians and 12% were commercial pilots. Comparison of the proportion of doctors among TO cases with that among other hip joint pathologies revealed a significant difference. Abnormal low hormone levels of testosterone and 25-cholicalciferol (vitamin D) were detected in three and two patients, respectively. CONCLUSION: The preponderance of physicians among patients with transient hip osteoporosis has not been previously reported. Etiological contribution of endocrine pathology and type of occupation to the causation of transient osteoporosis merits further research.

    This study was designed to assess the use of a 3D printing technique in total hip arthroplasty (THA) for severe hip deformities, where new and improved approaches are needed. THAs were performed from January 2015 to December 2016. Bioprosthesis artificial hip joints were used in both conventional and 3D printing hip arthroplasties. A total of 74 patients (57 cases undergoing conventional hip replacements and 17 undergoing 3D printing hip replacements) were followed-up for an average of 24 months. The average age of the patients was 62.7 years. Clinical data between the patients treated with different approaches were compared. Results showed that the time to postoperative weight bearing and the Harris scores of the patients in the 3D printing group were better than those for patients in the conventional hip replacement group. Unfortunately, the postoperative infection and loosening rates were higher in the 3D printing group. However, there were no significant differences in femoral neck anteversion, neck shaft, acetabular or sharp angles between ipsilateral and contralateral sides in the 3D printing group (P>0.05). The femoral neck anteversion angle was significantly different between the two sides in the conventional hip replacement group (P3D printing approach provides a better short-term curative effect that is more consistent with the physiological structure and anatomical characteristics of the patient, and we anticipate that its use will help improve the lives of many patients.

  13. HIP ROTATIONAL VELOCITIES DURING THE FULL GOLF SWING

    Directory of Open Access Journals (Sweden)

    Heather Gulgin

    2009-06-01

    Full Text Available Since labral pathology in professional golfers has been reported, and such pathology has been associated with internal/external hip rotation, quantifying the rotational velocity of the hips during the golf swing may be helpful in understanding the mechanism involved in labral injury. Thus, the purpose of this study was to determine the peak internal/external rotational velocities of the thigh relative to the pelvis during the golf swing. Fifteen female, collegiate golfers participated in the study. Data were acquired through high-speed three dimensional (3-D videography using a multi-segment bilateral marker set to define the segments, while the subjects completed multiple repetitions of a drive. The results indicated that the lead hip peak internal rotational velocity was significantly greater than that of the trail hip external rotational velocity (p = 0.003. It appears that the lead hip of a golfer experiences much higher rotational velocities during the downswing than that of the trail hip. In other structures, such as the shoulder, an increased risk of soft tissue injury has been associated with high levels of rotational velocity. This may indicate that, in golfers, the lead hip may be more susceptible to injury such as labral tears than that of the trailing hip

    2010-05-01

    A normally functioning hip joint is imperative for athletes who use their lower extremities with running, jumping, or kicking activities. Sports-related injuries of the hip and groin are far less frequent than injuries to the more distal aspect of the extremity, accounting for less than 10% of lower extremity injuries. Despite the lower incidence, hip and groin injuries can lead to significant clinical and diagnostic challenges related to the complex anatomy and biomechanical considerations of this region. Loads up to 8 times normal body weight have been documented in the joint in common daily activities, such as jogging, with significantly greater force expected during competitive athletics. Additionally, treatment for hip and groin injuries can obviate the participation of medical and surgical specialties, with a multidisciplinary approach frequently required. Delay in diagnosis and triage of these injuries may cause loss of time from competition and, potentially, early onset of degenerative changes. Magnetic resonance imaging (MRI) of the hip has proven to be the gold standard for the diagnosis of sports-related hip and groin injuries in the setting of negative radiographs. With its exquisite soft tissue contrast, multiplanar capabilities, and lack of ionizing radiation, MRI is unmatched in the noninvasive diagnosis of intra-articular and extra-articular pathology, as well as intraosseous processes. This review focuses on MRI of common athletic injuries of the hip and groin, including acetabular labral tears, femoral acetabular impingement syndrome, muscle injuries around the hip and groin (including athletic pubalgia), and athletic osseous injuries.

    Traumatic inferior hip dislocation is the least common of all hip dislocations. Adult inferior hip dislocations usually occur after high-energy trauma, very few cases are reported without fracture. A 26-year-old female was brought to the emergency department with severe pain in the left hip, impaired posture and restricted movement following a fall from 15m height. The hip joint was fixed in 90° flexion, 15° abduction, and 20° external rotation. No neurovascular impairment was determined. On radiologic examination, a left ischial type inferior hip dislocation was detected. Hemorrhagic shock which developed due to acute blood loss to thoracic and abdominal cavity and patient died at third hour after she was brought to the hospital. Traumatic hip dislocations have high morbidity and mortality rates due to multiple organ damage, primarily of the extremities, chest and abdomen. In the treatment of traumatic hip dislocation, closed reduction is recommended through muscle relaxation under general anesthesia or sedation. This procedure should be applied before any intervention for concomitant extremity injuries. A detailed evaluation on emergency presentation, a multi-disciplinary approach and early diagnosis with the rapid application of imaging methods could be life-saving for such patients.

    Hip hop dance has many styles including breakdance (breaking), house, popping and locking, funk, streetdance, krumping, Memphis jookin', and voguing. These movements combine the complexity of dance choreography with the challenges of gymnastics and acrobatic movements. Despite high injury rates in hip hop dance, particularly in breakdance, to date there are no published biomechanical studies in this population. The purpose of this study was to compare representative hip hop steps found in breakdance (toprock and breaking) and house and provide descriptive statistics of the angular displacements that occurred in these sequences. Six expert female hip hop dancers performed three choreographed dance sequences, top rock, breaking, and house, to standardized music-based tempos. Hip, knee, and ankle kinematics were collected during sequences that were 18 to 30 sec long. Hip, knee, and ankle three-dimensional peak joint angles were compared in repeated measures ANOVAs with post hoc tests where appropriate (pHip hop maximal joint angles exceeded reported activities of daily living and high injury sports such as gymnastics. Hip hop dancers work at weight-bearing joint end ranges where muscles are at a functional disadvantage. These results may explain why lower extremity injury rates are high in this population.

    Full Text Available Background: Children with myelomeningocele (MMC develop a wide variety of hip deformities such as muscle imbalance, contracture, subluxation, and dislocation. Various methods and indications have been introduced for treatment of muscle imbalances and other hip problems in patients with MMC but there is no study or meta-analysis to compare the results and complications. This review aims to find the most acceptable approach to hip problems in patients with MMC. Methods: MEDLINE was searched up to April 2015. All study designs that reported on the outcomes of hip problems in MMC were included. From 270 screened citations, 55 were strictly focused on hip problem in MMC were selected and reviewed. Results: Complex osseous and soft tissue reconstructive procedures to correct hip dysplasia and muscle balancing around the hip are rarely indicated for MMC patients without good quadriceps power. Conclusion: Over the years a consensus on the best algorithm for treatment of hip dislocation in myelomeningocele has been missing, however, muscular balancing with/out osseous procedure seems a reasonable approach especially in unilateral mid-lumbar MMC.

    Vania Regina Goveia

    Full Text Available OBJECTIVE: to characterize the epidemiological profile of patients undergoing hip replacement, primary or revisional. METHODS: we conducted a retrospective, descriptive study, including hip arthroplasties performed from January 2009 to June 2012 in a Belo Horizonte teaching hospital, Minas Gerais State - MG, Brazil. Data were analyzed using descriptive statistics. RESULTS: orthopedic procedures represented 45% of the operations at the hospital in the period, 1.4% hip arthroplasties. There were 125 hip replacements, 85 total, 27 partial and 13 reviews. Among the patients, 40% were male and 60% were female. Age ranged between 20 and 102 years, mean and median of 73 and 76 years, respectively. The most frequent diagnosis (82% was femoral neck fracture by low-energy trauma caused by falling form standing position. In 13 revision operations, 12 required removal of the prosthesis. The infectious complication led to revision in 54% of the time, followed by dislocation (15%, peri-prosthetic fracture (15% and aseptic loosening (15%. The infection etiologic agent was identified in 43% of occasions. The average length of the prosthesis to a revision operation was eight months. CONCLUSION: patients undergoing hip arthroplasty are elderly, with femoral neck fracture caused by falling form standing position, affecting more women. The incidence of hip prosthesis loosening was 10%. The main cause of the infection was loosening. The incidence of revisional hip arthroplasty was 10% and the incidence of hospital mortality in patients undergoing hip arthroplasty was 7.2%.

    García Pascual, E

    2015-06-01

    Repairing hip fractures is one of the most common surgical procedures and has greater morbidity and mortality. This procedure is also a process that involves a greater need for blood products. Numerous factors influence morbidity, mortality and the use of blood products: patient age, concomitant diseases and drug treatments that change hemostasis and hemorrhaging (preoperative, intraoperative and postoperative), which are usually significant. On top of all this is the presence in a high percentage of cases of preoperative anemia, which can have one or more causes. It is therefore essential to establish an appropriate management of perioperative anemia and optimize the transfusion policy. The aim of this review is to briefly analyze the epidemiology of hip fractures as well as establish a basis for treating perioperative anemia and transfusion policies, proposing guidelines and recommendations for clinical management based on the most current studies.

  17. Anchorage strategies in geriatric hip fracture management

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available There is an enormous humanitarian and socioeconomic need to improve the quality and effectiveness of care for patients with hip fracture. To reduce mechanical complications in the osteosynthesis of proximal femoral fractures, improved fixation techniques have been developed including blade or screw-anchor devices, locked minimally invasive or cement augmentation strategies. However, despite numerous innovations and advances regarding implant design and surgical techniques, systemic and mechanical complication rates remain high. Treatment success depends on secure implant fixation in often-osteoporotic bone as well as on patient-specific factors (fracture stability, bone quality, comorbidity, and gender and surgeon-related factors (experience, correct reduction, and optimal screw placement in the head/neck fragment. For fracture fixation, the anchorage of the lag screw within the femoral head plays a crucial role depending on the implant’s design. Meta-analyses and randomized controlled studies demonstrate that there is a strong trend towards arthroplasty treating geriatric femoral neck fractures. However, for young adults as well as older patients with less compromised bone quality, or in undisplaced fractures, head-preserving therapy is preferred as it is less invasive and associated with good functional results. This review summarizes the evidence for the internal fixation of femoral neck fractures and trochanteric femoral fractures in elderly patients. In addition, biomechanical considerations regarding implant anchorage in the femoral head including rotation, migration, and femoral neck shortening are made. Finally, cement augmentation strategies for hip fracture implants are evaluated critically.

    Femoral Acetabular Impingement (FAI) means a set of alterations involving the acetabulum, proximal femur, or both of these components that can results in osteoarthritis. Arthroscopy is a choice for the treatment of initial stages of osteoarthritis (OA) in order to reduce evolution of the degenerative processes; advanced degrees of osteoarthritis are absolute contraindications. 40 patients affected by osteoarthritis in FAI  underwent hip arthroscopy between May 2010 and March 2015. In all 40 cases OA secondary to FAI was diagnosed. All patients were clinically and instrumentally analyzed pre-operatively and then post-operatively after 3, 6, and 12 months. We evaluated the degree of OA using the Tonnis classification; our study included only patients affected by Tonnis grade 0-2 osteoarthritis. The mean modified Harris Hip Score showed an evolution from 54.7 points to an average value of 89,1 points after 12 months. The Lower Extremities Functional Scale evolved by 43 points to an average value of 65,28 points. Based on the data of this study, supported by the concordance with recent literature reviews, in degrees Tonnis 0 and 1 an arthroscopic treatment is recommended. Instead the therapeutic algorithm in Tonnis grade 2 is still being discussed. We detect a significant response to arthroscopic intervention which leads us to suggest that validation of this method needs further confirmatory studies.

The interdependencies among these elements and their correlations depended on factors including age, gender, place of residence, tobacco consumption, alcohol consumption, exposure to environmental pollution, physical activity, and type of degenerative change which were examined by statistical and chemometric methods. The factors that exerted the greatest influence on the elements in the femoral head and neck were tobacco smoking (higher Cr and Ni content in smokers, alcohol consumption (higher concentrations of Ni, Cu in people who consume alcohol, and gender (higher Cu, Zn, and Ni concentrations in men. The factors influencing Pb accumulation in bone tissue were tobacco, alcohol, gender, and age. In primary and secondary osteoarthritis of the hip, the content and interactions of elements are different (mainly those of Fe and Pb. There were no significant differences in the concentrations of elements in the femoral head and neck that could be attributed to residence or physical activity.

    2011-06-01

    The number of total hip replacement (THR) surgeries has increased significantly over the last few years and patients undergoing surgery are of decreasing age. In consequence the question of the influencing factors for the survival of artificial hip joints becomes more and more urgent. The expected survival time of an implant is nowadays 15-20 years and it seems that factors for a shorter lifetime are female gender, overweight, younger age and certain indications which led to surgery, such as rheumatoid arthritis or fractures. In the early phase of rehabilitation, measures against dislocation including training of the abductor muscles are most important. Starting rehabilitation programs early after surgery has positive effects on outcome, especially when strengthening programs are included. There are different opinions concerning the question how the lifetime of a THR is influenced by sports activities. However, it seems to have been demonstrated that suitable sports activities have a positive effect and do not necessarily correlate with higher loosening rates after THR. In general, high-impact sports should be avoided. Recommended activities are cycling, swimming, aquajogging, hiking, rowing and dancing.

    Hip and groin pain is a common clinical problem. Multiple causes can generate hip or groin pain, often sharing clinical and demographic characteristics. Diagnostic imaging tests play an important role in the etiological diagnosis. New forms of extra-articular hip impingement have recently been recognized as a cause of hip pain and limited function especially in young active patients. These conditions include ischiofemoral impingement, anterior inferior iliac spine and subspine impingement, iliopsoas impingement and greater trochanteric-pelvic impingement. In general, they are caused by a mechanical conflict with an abnormal or excessive contact between the proximal femur and pelvis and/or soft tissue between them. In this manuscript we review the physiopathology, clinical presentation, the most common radiologic findings and treatment of these forms of extra-articular hip impingement. Copyright © 2017 SERAM.

    Quantitative assessment of bone scintigraphy was performed in fifty-six patients with hip joint disease including femoral neck fracture, aseptic necrosis of the femoral head, traumatic dislocation of the hip, Perthes disease, and transient synovitis of the hip. In the static study, bone scintigraphy was obtained 3 hours after injection of sup(99m)Tc-MDP by gamma camera equipped with a computer and uptake ratios were calculated. In the dynamic study, bone scintigraphy was performed in one, 3 and 5 hours after injection of radionuclide. Femoral head uptake ratio was markedly decreased in osteonecrosis following femoral neck fracture and characteristically increased in aseptic necrosis of the femoral head but prolonged retention of sup(99m)Tc-MDP could be observed. Uptake ratios of epiphysis were decreased in Perthes disease but normal in transient synovitis of the hip. Static and dynamic study of bone scintigraphy may be useful for early diagnosis and treatment in the hip joint disease. (author).

    Wear debris from metal-on-polyethylene articulation in conventional total hip arthroplasty can limit the implant's longevity. Modern ceramic material with high wear resistance and low fracture risk has the potential to extend the lifetime of total hip arthroplasty, which makes the procedure potentially more suitable for young, active patients. Concerns with brittle ceramic material include fracture risk, the "squeak" phenomenon, and potentially a higher dislocation rate secondary to limited neck lengths and liner options. We therefore determined the early dislocation rate in modern ceramic-on-ceramic total hip arthroplasty. In 1635 total hip arthroplasties performed over the 9-year period (1996-2005), we observed three anterior and 15 posterior dislocations (1.1%). All were treated successfully, one with a revision and 17 with closed reduction under general anesthesia. Ceramic-on-ceramic total hip arthroplasty can be a good alternative bearing surface with a low dislocation rate.

    Full Text Available The aim of this study was to evaluate bacteria species detected in a large number of patients treated for prosthetic joint infection of the hip and knee at a single specialized center. Furthermore, the rate of implant loosening was investigated in a time-dependent manner for the most frequently detected bacteria species. A retrospective analysis of patients (n = 209 treated for prosthetic joint infection of the hip and knee was performed. The following parameters were evaluated: C-Reactive Protein (CRP concentration, microbiological evaluation of tissue samples, loosening of the implant, the time that had elapsed since the primary prosthetic joint replacement, and the duration since the last surgical intervention. Coagulase-negative Staphylococcus spp. were most frequently detected, followed by Staphylococcus aureus. Differences in CRP concentration were detected among various bacteria species. Osteolysis was not associated with one causative agent in particular. Patients who had undergone previous revision surgery had a higher probability of implant loosening. Coagulase-negative Staphylococcus spp. are the most common causative agents of prosthetic joint infection and show no significant differences with regard to implant loosening or the time-course when compared to S. aureus. Infections with Enterococcus spp. seem to develop faster than with other bacteria species. The risk of implant loosening increases with revision surgery, in particular in the hip joint.

    The demand for total hip replacement (THR) surgery is increasing in the younger population due to faster rehabilitation and more complete restoration of function. Up to 2009, metal-on-metal (MoM) hip joint bearings were a popular choice due to their design flexibility, post-operative stability and relatively low wear rates. The main wear mechanisms that occur along the bearing surface of MoM joints are tribochemical reactions that deposit a mixture of wear debris, metal ions and organic matrix of decomposed proteins known as a tribolayer. No in-depth electrochemical studies have been reported on the structure and characteristics of this tribolayer or about the parameters involved in its formation. In this study, we conducted an electrochemical investigation of different surfaces (bulk-like: control, nano-crystalline: new implant and tribolayer surface: retrieved implant) made out of two commonly used hip CoCrMo alloys (high-carbon and low-carbon). As per ASTM standard, cyclic polarization tests and electrochemical impedance spectroscopy tests were conducted. The results obtained from electrochemical parameters for different surfaces clearly indicated a reduction in corrosion for the tribolayer surface (Icorr: 0.76 μA/cm2). Further, polarization resistance (Rp:2.39±0.60MΩ/cm2) and capacitance (Cdl:15.20±0.75 μF/cm2) indicated variation in corrosion kinetics for the tribolayer surface, that attributed to its structure and stability in a simulated body environment.

    Hip fractures cause increased mortality and disability and consume enormous healthcare resources. Only 46% of hip fracture patients have osteoporosis at the total hip according to dual-energy X-ray absorptiometry (DXA) measurement. Cortical porosity increases with ageing and is believed to be important for bone strength. To investigate whether older women with hip fracture have higher cortical porosity than controls, and if so whether this difference is independent of clinical risk factors and areal bone mineral density (aBMD). From an ongoing population-based study, we identified 46 women with a prevalent X-ray-verified hip fracture and 361 control subjects without any fractures. aBMD was measured with DXA. High-resolution peripheral quantitative computed tomography was used to measure bone microstructure at the standard (ultradistal) site and at 14% (distal) of the tibial length. Women with a previous hip fracture had lower aBMD at the femoral neck (-11.8%) and total hip (-14.6%) as well as higher cortical porosity at the ultradistal (32.1%) and distal (29.3%) tibia compared with controls. In multivariable logistic regression analysis, with adjustment for covariates (age, height, weight, smoking, calcium intake, physical activity, walk time, oral glucocorticoids, parental hip fracture, rheumatoid arthritis, previous fall, current bisphosphonate treatment and femoral neck aBMD), cortical porosity at the ultradistal [odds ratio per standard deviation increase (95% confidence interval) 2.61 (1.77-3.85)] and distal [1.57 (1.12-2.20)] sites was associated with prevalent hip fracture. Cortical porosity was associated with prevalent hip fracture in older women independently of femoral neck aBMD and clinical risk factors. © 2017 The Authors.

    A hip fracture results in a lower quality of life and a cost of £30,000. In this study, one-leg standing time (OLST) had a negative linear relationship to the risk of a hip fracture. OLST could be a useful tool to assess the need for fracture-preventive interventions. A hip fracture immobilizes, restricts autonomy, shortens life expectancy, and results in a cost of £30,000 in the UK health care system. However, effective preventive treatments can be offered to high-risk individuals. Impaired postural balance is an important risk factor for hip fractures, and the aim of this study was to evaluate whether OLST can predict hip fractures in elderly women. FRAX is the most established fracture risk assessment tool worldwide and a secondary aim was to relate the predictive ability of OLST to that of FRAX in this population. Three hundred fifty-one women aged between 69 and 79 years were timed standing on one leg up to 30 s with eyes open and assessed with FRAX. Fracture data was obtained from registers. The main outcome, a hip fracture, occurred in 40 of the 351 participants (11.4%). The age-adjusted risk of a hip fracture was 5% lower with 1 s longer OLST (Hazard ratio 0.95, 95% CI 0.927-0.978). The relation between OLST and hip fracture risk was linear. Harrell's c was 0.60 for FRAX and 0.68 for OLST adjusted for age. With 1 s longer OLST, the risk of a hip fracture decreased significantly by 5%. This risk reduction was not explained by differences in the classic fracture risk factors included in FRAX. OLST had a predictive ability similar to FRAX. OLST is an easily performed balance test which may prove to be valuable in the assessment of hip fracture risk.

    Coxarthrosis is a chronic musculoskeletal condition that causes severe pain and considerable limi-tation of the patient's motor performance. Total hip arthroplasty is one of the most common and effective methods used in the treatment of advanced degenerative changes. The aim of the present study was to evaluate the activity and quality of life of patients after unilateral total hip arthroplasty. The study was conducted in a group of 189 patients who had undergone unilateral total hip arthroplasty. Goniometry was used to determine the range of motion of both hip joints. Patients' physical ability and pain severity were assessed based on the Harris Hip Score (HHS) questionnaire. The examination of the range of motion in the lower extremities revealed statistically significant diffe-rences in flexion (p<0.01), abduction (p=<0.01), adduction (p<0.01) and external rotation (p<0.01) between the operated and the healthy extremity. The greatest limitation of motion was demonstrated for external rotation (<14°). Approximately 14% of the patients were not able to perform this motion in their healthy hip joint, while 17.5% of them could not do so in the affected hip joint. Analysis of HHS results (mean = 79 pts) revealed that more than 50% of the patients described their functional ability and quality of life as good and excellent. It was demonstrated that 54% of patients did not suffer from pain, whereas minor or mild pain was noted in 35%. 1. A subjective clinical assessment of patients after total hip arthroplasty showed that their quality of life had improved. 2. It is necessary to perform physiotherapy after total hip arthroplasty, on both the operated and healthy side. 3. Exacerbation of pain and impaired activity in patients after total hip arthroplasty were associated with the female sex to a considerable extent.

    To summarize the short- and medium-term effectivenesses of stemless hip arthroplasty for treating hip joint disease in young and middle-aged patients. Between June 2005 and December 2010, 25 cases (27 hips) of hip joint disease were treated with stemless hip arthroplasty. There were 17 males (19 hips) and 8 females (8 hips) with an average age of 45.6 years (range, 30-57 years), including 13 left hips, 10 right hips, and 2 bilateral hips. The causes included avascular necrosis of the femoral head (ANFH) secondary to femoral neck fracture in 5 cases (5 hips), ANFH in 15 cases (16 hips), osteoarthritis of the hip joint caused by ankylosing spondylitis in 2 cases (3 hips), osteoarthritis of the hip joint caused by dysplasia of acetabular in 2 cases (2 hips), and rheumatoid arthritis in 1 case (1 hip). The disease duration was 1-17 years (mean, 6.1 years). Before operation, the Harris score was 47.6 ± 14.2. The incision healed by first intention in all patients, and no complications occurred, such as infection, periprosthetic fracture, and deep vein thrombosis of lower extremity. Twenty-five patients (27 hips) were followed up 36-96 months (mean, 51 months). One case (1 hip) had sciatic nerve injury after operation, which was relieved by symptomatic treatment. One case (1 hip) had prosthesis loosening, which was relieved after revision. The survival rate of prosthesis was 96.3% (26/27). At last follow-up, the Harris score was 92.1 ± 3.6, which was significantly better than preoperative score (t = 18.241, P = 0.000). The excellent and good rate was 88.9% (excellent in 19 hips, good in 5 hips, fair in 2 hips, and poor in 1 hip). The X-ray films showed good location of prosthesis, and no evidence of dislocation, bone resorption, osteolysis, and heterotopic ossification. Because of reserving femoral neck, biomechanics conduction and distribute of the proximal femur achieve natural biomechanics state of the human body. The short- and medium-term effectivenesses of

Failure to meet an adequate dietary intake is involved in the pathogenesis of sarcopenia and osteoporosis, which in turn increase the risk for falls and fractures, respectively. Older people with hip fracture are often protein-malnourished at hospitalization. Whether low protein-energy intake is associated with muscle atrophy in hip fractured patients is presently unknown. This information is necessary for the development of novel strategies to manage this especially vulnerable patient population. The aim of this study was therefore to explore the relationship between dietary intake and muscle mass in older hip fractured patients.Methods. Analyses were conducted in hip fractured elderly admitted to an orthopedic and trauma surgery ward (University Hospital. Muscle mass was estimated by bioelectrical impedance analysis within 24 h from admission. Dietary information was collected via 24-h dietary recall and nutrient intakes calculated by a nutrition software.Results. Among 62 hip fractured patients (mean age 84.6±7.6 years, 84% women, the average energy intake was 929.2±170.3 Kcal/day, with higher values reported by men (1.046.8±231.4 Kcal/day relative to women (906.5±148.3 Kcal/day; p=0.01. Absolute and normalized protein intake was 50.0±13.5 g/day and 0.88±0.27 g/kg (body weight/day, respectively, with no gender differences. A positive correlation was determined between total energy intake and muscle mass (r=0.384; p=0.003. Similarly, protein and leucine consumption was positively correlated with muscle mass (r=0.367 and 0.311, respectively; p=0.005 for both.Conclusions. A low intake of calories, protein and leucine is associated with reduced muscle mass in hip fractured elderly. Given the relevance of sarcopenia as a risk factor for adverse outcomes in this patient population, our findings highlight the importance of a comprehensive dietary assessment for the detection of nutritional deficits predisposing to or aggravating

    Researchers measure the significance of hip fracture by the patient's impairment. The patient's quality of life (QOL) is usually also substantially affected. However, there is no specific quality of life (QOL) questionnaire for patients with hip fractures. This study was designed to determine whether adding a new set of specific questions about…

    Total hip replacement is the most common procedure in the treatment of severe degenerative changes in the hip joint. The authors present clinical evaluation of 129 patients (151 hips) who underwent total hip replacement using either the Mittelmeier type or the Parhofer-Mönch type hip prothesis. The age of the patients ranged at the time of the operation between 17 and 74 years (average 44.9). The follow-up ranged from 24 to 143 months (average 61.2 months). The P-M prothesis was implanted in 53 hips, the P-M "Plasmapore" prothesis in 42 patients, Mittelmeier Autophor 900 prothesis in 49 patients and the Mittelmeier Autophor 900S prothesis in 7 patients. Clinical evaluation was performed according to the d'Aubigne-Postel method with the Charnley modification. The results were graded as very good in 17 cases, good in 64 cases, satisfactory in 53 cases and poor in 17 cases. Very good and good results were mainly observed after implantation of the P-M type prothesis and P-M "Plasmapore" type prothesis. Worse results were observed in patients, who at the time of the operation were aged 45 years or less and who had congenital hip dysplasia. P-M type prothesis gives better clinical results in the treatment of degenerative changes of the hip joint.

    Strengthening of the hip and trunk muscles has the potential to change lower limb kinematic patterns, such as excessive hip medial rotation and adduction during weight-bearing tasks. This study aimed to investigate the effect of hip and trunk muscles strengthening on hip muscle performance, hip passive properties, and lower limb kinematics during step-down task in women. Thirty-four young women who demonstrated dynamic knee valgus during step-down were divided into two groups. The experimental group underwent three weekly sessions of strengthening exercises for eight weeks, and the control group continued their usual activities. The following evaluations were carried out: (a) isokinetic maximum concentric and eccentric work of hip lateral rotators, (b) isokinetic hip passive torque of lateral rotation and resting transverse plane position, and (c) three-dimensional kinematics of the lower limb during step-down. The strengthening program increased concentric (Plower limb adduction during step-down. The changes in hip maximum work and resting position may have contributed to the observed kinematic effects.
