    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.

    Hip dysplasia is a common developmental problem affecting the canine population. Despite extensive research into the condition, many questions remain unanswered and numerous misconceptions are present among the general public. The purpose of this paper is to review the current knowledge on the development of hip dysplasia, factors modifying its development, and current diagnostic techniques. A computerized literature search was conducted for the period of January 1983 to April 1985 using the ...

  4. Pathophysiology, diagnosis, and treatment of canine hip dysplasia

    International Nuclear Information System (INIS)

    Dogs with hip dysplasia are commonly presented to veterinarians for evaluation. Although many causes of the condition have been proposed, a definitive cause has not been established. The multifactorial nature of canine hip dysplasia can confuse client education and management ofthe disease. The basic concept involved is the biomechanical imbalance between the forces on the coxofemoral joint and the associated muscle mass; the result is joint laxity in young, growing dogs. This laxity leads to incongruity; the eventual result is degenerative joint disease. Canine hip dysplasia can affect any breed but is most often reported in large and giant breeds. Understanding the pathophysiology and biomechanics involved with this developmental disease is important in providing clients with diagnostic, therapeutic, and prognostic information. The selection of treatment is influenced by the following factors:the age, health, and intended use of the patient; clinical signs; diagnostic findings; the availability of treatment; and the financial constraints of the owner. This article discusses the current concepts concerning the pathophysiology and biomechanics of canine hip dysplasia and outlines diagnostic and therapeutic options. The objective of the article is to provide practitioners with a reference for decision making and client education

    Full Text Available BACKGROUND: Canine hip dysplasia (HD is a common polygenic trait characterized by hip malformation that results in osteoarthritis (OA. The condition in dogs is very similar to developmental dysplasia of the human hip which also leads to OA. METHODOLOGY/PRINCIPAL FINDINGS: A total of 721 dogs, including both an association and linkage population, were genotyped. The association population included 8 pure breeds (Labrador retriever, Greyhounds, German Shepherd, Newfoundland, Golden retriever, Rottweiler, Border Collie and Bernese Mountain Dog. The linkage population included Labrador retrievers, Greyhounds, and their crosses. Of these, 366 dogs were genotyped at ∼22,000 single nucleotide polymorphism (SNP loci and a targeted screen across 8 chromosomes with ∼3,300 SNPs was performed on 551 dogs (196 dogs were common to both sets. A mixed linear model approach was used to perform an association study on this combined association and linkage population. The study identified 4 susceptibility SNPs associated with HD and 2 SNPs associated with hip OA. CONCLUSION/SIGNIFICANCE: The identified SNPs included those near known genes (PTPRD, PARD3B, and COL15A1 reported to be associated with, or expressed in, OA in humans. This suggested that the canine model could provide a unique opportunity to identify genes underlying natural HD and hip OA, which are common and debilitating conditions in both dogs and humans.

    Full Text Available Emma R Schachner, Mandi J Lopez Department of Veterinary Clinical Sciences, School of Veterinary Medicine, Louisiana State University, Baton Rouge, LA, USA Abstract: Canine hip dysplasia (CHD is a polygenic and multifactorial developmental disorder characterized by coxofemoral (hip joint laxity, degeneration, and osteoarthritis (OA. Current diagnostic techniques are largely subjective measures of joint conformation performed at different stages of development. Recently, measures on three-dimensional images generated from computed tomography scans predicted the development of OA associated with CHD. Continued refinement of similar imaging methods may improve diagnostic imaging techniques to identify dogs predisposed to degenerative hip joint changes. By current consensus, joint changes consistent with CHD are influenced by genetic predisposition as well as environmental and biomechanical factors; however, despite decades of work, the relative contributions of each to the development and extent of CHD signs remain elusive. Similarly, despite considerable effort to decipher the genetic underpinnings of CHD for selective breeding programs, relevant genetic loci remain equivocal. As such, prevention of CHD within domestic canine populations is marginally successful. Conservative management is often employed to manage signs of CHD, with lifelong maintenance of body mass as one of the most promising methods. Surgical intervention is often employed to prevent joint changes or restore joint function, but there are no gold standards for either goal. To date, all CHD phenotypes are considered as a single entity in spite of recognized differences in expression and response to environmental conditions and treatment. Identification of distinct CHD phenotypes and targeting evidence-based conservative and invasive treatments for each may significantly advance prevention and management of a prevalent, debilitating condition in canine companions.

This trait was described in the dog in 1935 and leads to a debilitating secondary hip osteoarthritis. The diagnosis is confirmed radiographically by evaluating signs of degenerative joint disease, incongruence, and/or passive hip joint laxity. There is no ideal medical or surgical treatment so prevention based on controlled breeding is the optimal approach. The definitive CHD diagnosis based on radiographic examination involves the exposure to ionizing radiation under general anesthesia or heavy sedation but the image does not reveal the underlying genetic quality of the dog. Phenotypic expression of CHD is modified by environmental factors and dogs with a normal phenotype can be carriers of some mutations and transmit these genes to their offspring. Programs based on selection of dogs with better individual phenotypes for breeding are effective when strictly applied but remain inferior to the selection of dogs based on estimation of breeding values. Molecular studies for dissecting the genetic basis of CHD are ongoing, but progress has been slow. In the future, the recommended method to improve hip quality in controlled breeding schemes, which will allow higher selection pressure, would be based on the estimation of the genomic breeding value. Since 2012, a commercial DNA test has been available for Labrador Retrievers using a blood sample and provides a probability for

    Sophia Pfahler

    Full Text Available A genome-wide association study for canine hip dysplasia (CHD and canine elbow dysplasia (CED using the Illumina canine high density bead chip had been performed for 174 Bernese mountain dogs. General and mixed linear model analysis identified two different regions with single nucleotide polymorphisms (SNPs on dog chromosome (CFA 14 significantly associated with CHD and a further significantly CHD-associated region on CFA37. For CED, four SNPs on CFA11 and 27 were significantly associated. The identified SNPs of four associated regions included nearby candidate genes. These possible positional candidates were the genes PON2 on CFA14 and FN1 on CFA37 for CHD and the genes LMNB1 on CFA11 and WNT10B on CFA27 for CED.

    Full Text Available Increased concern for the welfare of pedigree dogs has led to development of selection programs against inherited diseases. An example is canine hip dysplasia (CHD, which has a moderate heritability and a high prevalence in some large-sized breeds. To date, selection using phenotypes has led to only modest improvement, and alternative strategies such as genomic selection may prove more effective. The primary aims of this study were to compare the performance of pedigree- and genomic-based breeding against CHD in the UK Labrador retriever population and to evaluate the performance of different genomic selection methods. A sample of 1179 Labrador Retrievers evaluated for CHD according to the UK scoring method (hip score, HS was genotyped with the Illumina CanineHD BeadChip. Twelve functions of HS and its component traits were analyzed using different statistical methods (GBLUP, Bayes C and Single-Step methods, and results were compared with a pedigree-based approach (BLUP using cross-validation. Genomic methods resulted in similar or higher accuracies than pedigree-based methods with training sets of 944 individuals for all but the untransformed HS, suggesting that genomic selection is an effective strategy. GBLUP and Bayes C gave similar prediction accuracies for HS and related traits, indicating a polygenic architecture. This conclusion was also supported by the low accuracies obtained in additional GBLUP analyses performed using only the SNPs with highest test statistics, also indicating that marker-assisted selection would not be as effective as genomic selection. A Single-Step method that combines genomic and pedigree information also showed higher accuracy than GBLUP and Bayes C for the log-transformed HS, which is currently used for pedigree based evaluations in UK. In conclusion, genomic selection is a promising alternative to pedigree-based selection against CHD, requiring more phenotypes with genomic data to improve further the accuracy

    Hip dysplasia (HD) scores, based on the five grades, as defined by the Fédération Cynologique Internationale, were compared between anaesthetized (group 1, n = 3839) and non-sedated non-anaesthetized dogs (group 2, n = 1517). Each dog was radiographed in the standard ventro-dorsal hip joint extended position. Each radiograph was evaluated by the same reader blinded regarding the dog's status of anaesthesia. Results showed that there was a significant difference in hip dysplasia prevalence between group 1 (22%) compared with group 2 (9%) (P < 0.005). This difference was the result of a lower rate of hip-joint laxity assessment and the measurement of Norberg-Olsson angle <105 degrees in group 2 compared with group 1. The acetabular and femoral morphologies were not significantly different between the groups. The data confirm that the scoring of dogs for HD on standard radiographs with the hip joints extended is influenced by anaesthesia. PMID:16970631

    Full Text Available Aim: The current study was undertaken to evaluate the findings of canine hip dysplasia screening in Kenya. Materials and Methods: Records for 591 dogs were included in this study. The data was obtained from the national screening office, Kenya Veterinary Board, for the period between the years 1998 and 2014. Monthly screening records were assessed and information relating to year of evaluation, breed, sex, age, and hip score captured. Descriptive statistics of hip scores was computed based on year, sex, age, and breed. Results: A total of 591 records from the year 1998 to 2014 were retrieved at the National Screening Centre, the Kenya Veterinary Board. Each record was examined and data pertaining to year of screening, the breed, sex, age of the dogs, and the total hip score were recorded. The highest number of dogs screened for hip dysplasia (HD was in the year 2009 and the lowest in the year 1998. More females than males were screened for HD and the mean age of all the dogs was 22.9±12.7 months. The most common breeds of dogs screened during the study period were German Shepherd (67.0%, Rottweiler (15.6%, and Labrador Retriever (12.2%. The mean hip score for the 591 dogs was 15.1±10.9 and the median 12.0. The mean hip scores per breed were; German Shepherd (16.3±12.1; Golden Retriever (16.0; Hungarian Vizla (15.0; Labrador Retriever (3.0±6.7; Great Dane (13.3±3.2; Rottweiler (12.2±8.2; Doberman (10.3±4.2; Rhodesian Ridgeback (9.6±3.8; and Boxer (9.3±0.6. Based on the hip score, moderate to severe HD was diagnosed in 16.6% of the dogs, mild HD in 32.7%, Borderline HD in 37.7%, fair HD in 6.9%, and good HD in 6.1%. Conclusion: Canine HD is a common occurrence in Kenya with most dogs suffering mild to border line HD. In addition, German Shepherd and Golden Retriever appear to be the most affected breeds. It is therefore recommended that stringent measures be imposed to dog breeding programs to avoid transmission of this undesirable trait

    Full Text Available Canine hip dysplasia is one of the most prevalent developmental orthopedic diseases in dogs worldwide. Unfortunately, the success of eradication programs against this disease based on radiographic diagnosis is low. Adding the use of diagnostic genetic tools to the current phenotype-based approach might be beneficial. The aim of this study was to develop a genetic prognostic test for early diagnosis of hip dysplasia in Labrador Retrievers. To develop our DNA test, 775 Labrador Retrievers were recruited. For each dog, a blood sample and a ventrodorsal hip radiograph were taken. Dogs were divided into two groups according to their FCI hip score: control (A/B and case (D/E. C dogs were not included in the sample. Genetic characterization combining a GWAS and a candidate gene strategy using SNPs allowed a case-control population association study. A mathematical model which included 7 SNPs was developed using logistic regression. The model showed a good accuracy (Area under the ROC curve = 0.85 and was validated in an independent population of 114 dogs. This prognostic genetic test represents a useful tool for choosing the most appropriate therapeutic approach once genetic predisposition to hip dysplasia is known. Therefore, it allows a more individualized management of the disease. It is also applicable during genetic selection processes, since breeders can benefit from the information given by this test as soon as a blood sample can be collected, and act accordingly. In the authors' opinion, a shift towards genomic screening might importantly contribute to reducing canine hip dysplasia in the future. In conclusion, based on genetic and radiographic information from Labrador Retrievers with hip dysplasia, we developed an accurate predictive genetic test for early diagnosis of hip dysplasia in Labrador Retrievers. However, further research is warranted in order to evaluate the validity of this genetic test in other dog breeds.

  14. Canine hip dysplasia: phenotypic scoring and the role of estimated breeding value analysis.

    Canine hip dysplasia (CHD) is a developmental orthopaedic disease of the coxofemoral joints with a multifactorial mode of inheritance. Multiple gene effects are influenced by environmental factors; therefore, it is unlikely that a simple genetic screening test with which to identify susceptible individuals will be developed in the near future. In the absence of feasible methods for objectively quantifying clinical CHD, radiographic techniques have been developed and widely used to identify dogs for breeding which are less affected by the disease. A hip-extended ventrodorsal view of the pelvis has been traditionally used to identify dogs with subluxation and/or osteoarthritis of the coxofemoral joints. More recently, there has been emphasis on the role of coxofemoral joint laxity as a determinant of CHD and methods have been developed to measure passive hip laxity. Though well-established worldwide, the effectiveness of traditional phenotypic scoring schemes in reducing the prevalence of CHD has been variable. The most successful implementation of traditional CHD scoring has occurred in countries or breeding colonies with mandatory scoring and open registries with access to pedigree records. Several commentators have recommended that for quantitative traits like CHD, selection of breeding stock should be based on estimated breeding values (EBV) rather than individual hip score/grade. The EBV is a reflection of the genetic superiority of an animal compared to its counterparts and is calculated from the phenotype of an individual and its relatives and their pedigree relationship. Selecting breeding stock on the basis of a dog's genetic merit, ideally based on a highly predictive phenotype, will confer the breeder with greater selection power, accelerate genetic improvement towards better hip conformation and thus more likely decrease the prevalence of CHD.

    International Nuclear Information System (INIS)

    This article questions the stagnation of breeding results by hip dysplasia screening and its current etiology. The ''Coxa Valga Antetorta'', anteversion of the hip joint and ''soft tissue displasia'' are discussed besides a multitude of primary diseases leading to growth deformities and other diseases in the hip. Ectopic primary causes like malformation of the spine leading to a secondary ''dysplatic'' osteoarthritis of the hip (functional secondary dysplasia) are also discussed in this article. Recent and very promising breeding strategies (estimation of the breeding value) in the battle against hip dysplasia are presented. Biochemical, immunological and structural aspects are presented as a not totally utopic perspecitive. Molecular genetic markers for hip dysplasia will offer in the near future a possibility to detect carriers ct the disease by a blood sample ion before clinical manifestation

  17. Early detection of canine hip dysplasia: comparison of two palpation and five radiographic methods

    International Nuclear Information System (INIS)

    Hip joint laxity was evaluated in four breeds (i.e., greyhound, Labrador retriever, Irish setter, hound mixed-breed) of puppies (n=32) by Ortolani's and Bardens' maneuvers, by subjective assessment of radiographs (Orthopedic Foundation for Animals [OFA] method), and by four radiographic measurement indices. Puppies were studied at four, six-to-10, 16-to-18, and 52 weeks of age. The purpose of this study was to compare palpation and radiographic methods of hip laxity detection in puppies for predicting the development of degenerative joint disease (DJD) by one year of age. Twenty-seven (42%) hips developed DJD. Ortolani's method was not a reliable predictor of hip dysplasia at six-to-10 weeks; it was significantly predictive at 16-to-18 weeks but had a high incidence of false negatives. Bardens' and subjective (OFA) assessment methods were not reliable at six-to-10 or 16-to-18 weeks. Radiographic measurements taken with femurs in a neutral position and hips distracted (distraction index [DI] and Norberg angle) and measurements taken with femurs extended in OFA position (Norberg angle) of six- to 10-week-old puppies accurately predicted DJD occurrence by one year of age (p less than 0.01). Distraction index measurement (PennHIP method) was the most accurate in predicting the development of DJD (p less than 0.001). Distraction index radiography in puppies six-to-10 and 16-to-18 weeks of age was the most reliable predictor of hip dysplasia. Norberg angle measurement was more reliable during hip distraction than when hips were measured in the OFA position in 16- to 18-week-old puppies, but had similar reliability in six- to 10-week-old puppies

    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.

    Lena Fels

    Full Text Available Canine hip dysplasia (CHD is the most common hereditary skeletal disorder in dogs. To identify common alleles associated with CHD, we genotyped 96 German Shepherd Dogs affected by mild, moderate and severe CHD and 96 breed, sex, age and birth year matched controls using the Affymetrix canine high density SNP chip. A mixed linear model analysis identified five SNPs associated with CHD scores on dog chromosomes (CFA 19, 24, 26 and 34. These five SNPs were validated in a by sex, age, birth year and coancestry stratified sample of 843 German Shepherd Dogs including 277 unaffected dogs and 566 CHD-affected dogs. Mean coancestry coefficients among and within cases and controls were <0.1%. Genotype effects of these SNPs explained 20-32% of the phenotypic variance of CHD in German Shepherd Dogs employed for validation. Genome-wide significance in the validation data set could be shown for each one CHD-associated SNP on CFA24, 26 and 34. These SNPs are located within or in close proximity of genes involved in bone formation and related through a joint network. The present study validated positional candidate genes within two previously known quantitative trait loci (QTL and a novel QTL for CHD in German Shepherd Dogs.

  2. Heritability and phenotypic variation of canine hip dysplasia radiographic traits in a cohort of Australian German shepherd dogs.

    Directory of Open Access Journals (Sweden)

    Bethany J Wilson

    Full Text Available Canine Hip Dysplasia (CHD is a common, painful and debilitating orthopaedic disorder of dogs with a partly genetic, multifactorial aetiology. Worldwide, potential breeding dogs are evaluated for CHD using radiographically based screening schemes such as the nine ordinally-scored British Veterinary Association Hip Traits (BVAHTs. The effectiveness of selective breeding based on screening results requires that a significant proportion of the phenotypic variation is caused by the presence of favourable alleles segregating in the population. This proportion, heritability, was measured in a cohort of 13,124 Australian German Shepherd Dogs born between 1976 and 2005, displaying phenotypic variation for BVAHTs, using ordinal, linear and binary mixed models fitted by a Restricted Maximum Likelihood method. Heritability estimates for the nine BVAHTs ranged from 0.14-0.24 (ordinal models, 0.14-0.25 (linear models and 0.12-0.40 (binary models. Heritability for the summed BVAHT phenotype was 0.30 ± 0.02. The presence of heritable variation demonstrates that selection based on BVAHTs has the potential to improve BVAHT scores in the population. Assuming a genetic correlation between BVAHT scores and CHD-related pain and dysfunction, the welfare of Australian German Shepherds can be improved by continuing to consider BVAHT scores in the selection of breeding dogs, but that as heritability values are only moderate in magnitude the accuracy, and effectiveness, of selection could be improved by the use of Estimated Breeding Values in preference to solely phenotype based selection of breeding animals.

    In human genetics and orthopedics quite different answers have been given to the question of hereditary transmission and frequency of hip dysplasia in families of children with congenital hip dislocation. We therefore have made roentgenometric measurements of 110 parents of children with congenital hip dislocation. In 25% we found abnormal flat acetabulae, whereas 12% had pathologic deep hips. This may propose a new concept of morphology of congenital hip dysplasia.

  4. Estimated breeding values for canine hip dysplasia radiographic traits in a cohort of Australian German Shepherd dogs.

    Bethany J Wilson

    Full Text Available Canine hip dysplasia (CHD is a serious and common musculoskeletal disease of pedigree dogs and therefore represents both an important welfare concern and an imperative breeding priority. The typical heritability estimates for radiographic CHD traits suggest that the accuracy of breeding dog selection could be substantially improved by the use of estimated breeding values (EBVs in place of selection based on phenotypes of individuals. The British Veterinary Association/Kennel Club scoring method is a complex measure composed of nine bilateral ordinal traits, intended to evaluate both early and late dysplastic changes. However, the ordinal nature of the traits may represent a technical challenge for calculation of EBVs using linear methods. The purpose of the current study was to calculate EBVs of British Veterinary Association/Kennel Club traits in the Australian population of German Shepherd Dogs, using linear (both as individual traits and a summed phenotype, binary and ordinal methods to determine the optimal method for EBV calculation. Ordinal EBVs correlated well with linear EBVs (r = 0.90-0.99 and somewhat well with EBVs for the sum of the individual traits (r = 0.58-0.92. Correlation of ordinal and binary EBVs varied widely (r = 0.24-0.99 depending on the trait and cut-point considered. The ordinal EBVs have increased accuracy (0.48-0.69 of selection compared with accuracies from individual phenotype-based selection (0.40-0.52. Despite the high correlations between linear and ordinal EBVs, the underlying relationship between EBVs calculated by the two methods was not always linear, leading us to suggest that ordinal models should be used wherever possible. As the population of German Shepherd Dogs which was studied was purportedly under selection for the traits studied, we examined the EBVs for evidence of a genetic trend in these traits and found substantial genetic improvement over time. This study suggests the use of ordinal EBVs could

    Full Text Available Introduction. Hip dysplasia is the elementary form of the developmental dysplasia of the hip (DDH. The diagnosis may be made by the ultrasound examination (types II a-, II b. Objective. The aim of the authors was to define the congenital structural neonatal hip dysplasia, and to differentiate hip hypoplasia, hip dysplasia and teratogenic anomalies. Methods. In all the cases, the uniform clinical and ultrasound tests were performed. All the patients were examined in the neonatal period of life (the first six weeks. The following clinical tests were used: Le Damany-Ortolany, Coleman-Barlow-Palmen and Weissman-Strinović. For the ultrasound examination, the Graph’s method was used. Results. The investigation was performed in the period 2007- 2008. 2,878 neonates were included. The distribution of the sonotypes, according to Graph, was as follows: Ia in 16.17%. Ib in 65.08%; IIa+ in 18.17%, IIc in 0.28%, IId in 0.19%; IIIa in 0.009%, IIIb in 0.02%; and IV in 0.01%. It was found that DDH was 8 times more frequent in girls; located more frequently at the left side than bilaterally. Conclusion. Hip sonoscreening has to be performed in all newborns in the first 72 hours. The suggested follow-up period is six weeks: for the diagnosis - the first three weeks, and for the prevention and treatment - all six weeks.

    The prevalence of rotation of the pelvis along its length axis was noted, as was the number of rotations towards the right or left hand side of the dog, on 7,012 conventional hip extended radiographs, which were sent for official screening. 29.8% of the radiographs showed a rotation the pelvis. The rotation was statistically more frequent towards the left hand side of the dog. The number of rejected radiographs for too important pelvis rotation was only 5.2%. The consequences of the pelvis rotation on the Norberg-Olsson angle, on the dorsal femoral head coverage, and in the aspect of cranial acetabular edge have to be taken into account when scoring the dog for hip dysplasia.

    Objective Hip arthroscopy in the setting of hip dysplasia is controversial in the orthopaedic community, as the outcome literature has been variable and inconclusive. We hypothesise that outcomes of hip arthroscopy may be diminished in the setting of hip dysplasia, but outcomes may be acceptable in milder or borderline cases of hip dysplasia. Methods A systematic search was performed in duplicate for studies investigating the outcome of hip arthroscopy in the setting of hip dysplasia up to July 2015. Study parameters including sample size, definition of dysplasia, outcomes measures, and re-operation rates were obtained. Furthermore, the levels of evidence of studies were collected and quality assessment was performed. Results The systematic review identified 18 studies investigating hip arthroscopy in the setting of hip dysplasia, with 889 included patients. Criteria used by the studies to diagnose hip dysplasia and borderline hip dysplasia included centre edge angle in 72% of studies but the range of angles were quite variable. Although 89% of studies reported improved post-operative outcome scores in the setting of hip dysplasia, revision rates were considerable (14.1%), with 9.6% requiring conversion to total hip arthroplasty. Conclusion The available orthopaedic literature suggests that although improved outcomes are seen in hip arthroscopy in the setting of hip dysplasia, there is a high rate of re-operation and conversion to total hip arthroplasty. Furthermore, the criteria used to define hip dysplasia vary considerably among published studies. Cite this article: M. Yeung, M. Kowalczuk, N. Simunovic, O. R. Ayeni.

  12. Genetic correlations among canine hip dysplasia radiographic traits in a cohort of Australian German Shepherd Dogs, and implications for the design of a more effective genetic control program.

    Full Text Available Canine hip dysplasia (CHD is a common musculoskeletal disease in pedigree dog populations. It can cause severe pain and dysfunction which may require extensive medication and/or surgical treatment and often ultimately requires humane euthanasia. CHD has been found to be moderately heritable and, given its impact on welfare, should be considered an imperative breeding priority. The British Veterinary Association/Kennel Club scoring method is one of several measures used to assess the genetic propensity of potential breeding stock for dysplastic changes to the hips based on radiographic examination. It is a complex measure composed of nine ordinal traits, intended to evaluate both early and late dysplastic changes. It would be highly desirable if estimated breeding values (EBVs for these nine traits were consolidated into a simpler, EBV-based, selection index more easily usable by breeders. A multivariate analysis on the phenotype scores from an Australian cohort of 13,124 German Shepherd Dogs (GSDs returned genetic correlations between 0.48-0.97 for the nine traits which fell into two trait groups, Group 1 reflecting early changes ("laxity" and Group 2 reflecting late changes ("osteoarthritis". Principal components analysis of the ordinal EBVs suggested the same pattern, with strong differentiation between "laxity" and "osteoarthritis" traits in the second component. Taking account of all results, we recommend interim use of two selection indexes: the first being the average of ordinal EBVs for "laxity" traits and the second being the average of ordinal EBVs for "osteoarthritis" traits. The correlation between these two selection indexes (0.771-0.774 is sufficiently less than unity enabling the selection of dogs with different genetic propensity for laxity and for osteoarthritic CHD changes in GSDs; this may also be applicable in other breeds. Dogs with low propensity for severe osteoarthritic change in the presence of laxity may be of interest

    Full Text Available A technique to restore acetabular anatomy by deepening the acetabular cavity and reconstructing the femoral head ligament and the joint capsule was tested on nine large breed dogs with severe hip dysplasia and acute subdislocation or dislocation. The technique consisted of two phases. First, all dogs were submitted to bilateral pectinotomy. In a second surgical intervention on the same dogs the acetabulum was approached and deepened, and the femoral head ligament and the joint capsule were reconstructed. In general, within 30 days of the surgery dogs could stand on the operated member to walk. Except for two dogs, all the others recovered pelvic member locomotive ability within 60-90 days after surgery. It is concluded that acetabuloplasty is a good alternative for treatment of severe canine hip dysplasia.Uma técnica para restituir a anatomia acetabular com aprofundamento da cavidade acetabular e reconstrução do ligamento da cabeça do fêmur e da cápsula articular, foi testada em nove cães, de raças de grande porte, portadores de displasia coxofemoral grave com subluxação acentuada ou luxação. O procedimento cirúrgico foi constituído de duas fases. Inicialmente, foi realizada a pectineotomia bilateral em todos os cães. A segunda intervenção nos mesmos cães incluiu abordagem e aprofundamento do acetábulo, reconstrução do ligamento da cabeça do fêmur e da cápsula. Em geral, 30 dias após a cirurgia, os cães apoiavam o membro operado para se locomover. Com exceção de dois cães, todos os outros recuperaram a função locomotora do membro pélvico dentro de 60-90 dias. É concluído que a técnica de acetabuloplastia é uma boa alternativa para o tratamento da displasia coxofemoral grave.

    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.

    2010-10-01

    Full Text Available Developmental dysplasia of the hip (DDH is a spectrum of anatomical abnormalities of the hip joint in which the femoral head has an abnormal relationship with the acetabulum. Most studies report an incidence of 1 to 34 cases per 1,000 live births and differences could be due to different diagnostic methods and timing of evaluation. Risk factors include first born status, female sex, positive family history, breech presentation and oligohydramnios. Clinical presentations of DDH depend on the age of the child. Newborns present with hip instability, infants have limited hip abduction on examination, and older children and adolescents present with limping, joint pain, and/or osteoarthritis. Repeated, careful examination of all infants from birth and throughout the first year of life until the child begins walking is important to prevent late cases. Provocative testing includes the Barlow and Ortolani maneuvers. Other signs, such as shorting of the femur with hips and knees flexed (Galeazzi sign, asymmetry of the thigh or gluteal folds, and discrepancy of leg lengths are potential clues. Treatment depends on age at presentation and outcomes are much better when the child is treated early, particularly during the first six months of life.

    Full Text Available ABSTRACT We evaluated 160 hip joint radiographs of 40 dogs of different large breeds (25 females and 15 males from the metropolitan area of Belo Horizonte, Minas Gerais, Brazil. The radiographs of each dog were obtained at two different stages: stage 1 (mean 7.23 months and stage 2 (mean 14.25. The conventional radiographic method (CRM and the radiographic distraction method (RDM were used, carried out in both stages. CRM measured the Norberg angle (NA, the angle of inclination (AI and evaluated the presence of degenerative joint disease (DJD. The MRD was performed to establish the distraction index (DI. The aims were to evaluate the presence of the Morgan line and other signs of DJD and correlate them with the degree of canine hip dysplasia (CHD and also check if the DI greater than 0.3 (first stage was associated with the presence of ML (second stage. It was found that DI, AI and changes of femoral neck and the formation of osteophytes were associated with the presence of ML. It was observed that if the DI is greater than 0.3 at the first stage, the chance of a positive outcome of ML in the second stage increases by 7.2 times. Thus, 49 joints showed DI > 0.3 at the first stage, in which 31 (63.3 % presented ML at the second stage. Of the 31 animals that showed DI ≤ 0.3 at first, six (19.4% had LM at the second stage. There has been a significant association between the presence of ML and the degree of CHD. The more severe the CHD, the higher the percentage of positive ML results. Thus, among the 24 (60 % animals that showed ML, 11 (45.83 % were classified as severe dysplastics, 5 (20.83% as moderate and 8 (33.33 % as mild. None of the animals classified as normal or borderline presented ML. Among the 8 animals classified as mild dysplastics, 5 showed only ML as DJD.

    Congenital hip dysplasia and hip dislocation are relatively common pathological conditions of the musculoskeletal system in infants. An early and certain diagnosis can now be achieved by sonographic hip screening within the framework of screening examination programs. This early diagnostic procedure in infants is essential particularly for a conservative treatment strategy. Therefore, apart from possessing in-depth knowledge, training of the examiner in specialist courses is of central importance. This article presents an overview of the entity of congenital hip dysplasia and hip dislocation, the diagnostics and treatment with special emphasis on recent developments. PMID:26489825

    Full Text Available A desnervação capsular (DC se baseia na desperiostização da borda acetabular e tem sido utilizada como uma das técnicas de alívio da dor articular em cães displásicos. Compararam-se as técnicas de DC percutânea e aberta, aplicadas em 25 cães, que apresentaram diagnóstico clínico e radiográfico de displasia coxofemoral, totalizando 31 cirurgias. Os efeitos das técnicas foram comparados, em período de 180 dias, por meio de avaliação subjetiva de claudicação e dor, perimetria da coxa, graus máximos de flexão e extensão da articulação coxofemoral e amplitude de movimento articular. Os graus de claudicação e dor apresentaram decréscimo significativo ao longo do período avaliado em ambos os grupos, sem apresentarem diferenças quando comparados entre si. Com relação à perimetria da coxa, flexão, extensão e amplitude de movimento articular, foi observado o aumento dos valores numéricos destas variáveis ao longo do estudo. Baseado nos achados, concluiu-se que a abordagem percutânea ou aberta na DC produz similitude nas variáveis avaliadas, e ambas trazem bons resultados.Joint capsule denervation is based on removal of sensitive fibers from the acetabular edge and has been used as one of the techniques to joint pain relief in the canine dysplastic hip.

    Background: Reliable assessment of hip dysplasia and osteoarthritis is crucial in young adults who may benefit from joint-preserving surgery. Purpose: To investigate the variability of different methods for diagnostic assessment of hip dysplasia and osteoarthritis. Material and Methods: By each of four observers, two assessments were done by vision and two by angle construction. For both methods, the intra- and interobserver variability of center-edge and acetabular index angle assessment were analyzed. The observers' ability to diagnose hip dysplasia and osteoarthritis were assessed. All measures were compared to those made on computed tomography scan. Results: Intra- and interobserver variability of angle assessment was less when angles were drawn compared with assessment by vision, and the observers' ability to diagnose hip dysplasia improved when angles were drawn. Assessment of osteoarthritis in general showed poor agreement with findings on computed tomography scan. Conclusion: We recommend that angles always should be drawn for assessment of hip dysplasia on pelvic radiographs. Given the inherent variability of diagnostic assessment of hip dysplasia, a computed tomography scan could be considered in patients with relevant hip symptoms and a center-edge angle between 20 deg and 30 deg. Osteoarthritis should be assessed by measuring the joint space width or by classifying the Toennis grade as either 0-1 or 2-3

    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.

    2013-01-01

    A periacetabular osteotomy (PAO) is the preferred joint preserving treatment for young adults with symptomatic hip dysplasia and no osteoarthritis. In symptomatic dysplasia of the hip, there is labral pathology in up to 90% of cases. However, no consensus exists as to whether a labral tear should be treated before the periacetabular osteotomy (PAO), treated simultaneously with the PAO, or left alone and only treated if symptoms persist after the PAO. This review is an update of aspects of lab...

    Full Text Available Aim: We aimed to determine the frequency of cases with developmental hip dysplasia during the neonatal period and the associated risk factors. Methods: Hip ultrasound images of 258 full-term newborns aged one month were evaluated prospectively in conjunction with physical examination for developmental hip dysplasia in GATA well baby outpatient clinic. Results: The incidence of developmental hip dysplasia was 0.3% in one-month-old, healthy, full-term babies included in the study. 44% of them were male and 56% were female. The mean birth weight was 3311.8±511.4 g. 48% of all births were spontaneous vaginal deliveries and 52% cesarean deliveries. A history of oligohydramniosis was present in 8% of cases, 1% had breech presentation, 7% had a family history of developmental dysplasia and 7% had been swaddled. Additional congenital anomaly and torticollis were not detected at the physical examination of the babies. The risk factors were determined to be twin birth and female gender in the only baby who had developmental hip dysplasia (Type 2a. Conclusion: Developmental hip displasia is a significant public health concern in developing countries. Physical examination performed in conjunction with hip ultrasonography routinely in the neonatal period may contribute to the early diagnosis and treatment.

    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.

    Ineke C M Lavrijsen

    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.

  5. Bernese periacetabular osteotomy for hip dysplasia: Surgical technique and indications.

    Kamath, Atul F

    2016-05-18

    For young, active patients with healthy hip cartilage, pelvic osteotomy is a surgical option in to address hip pain and to improve mechanical loading conditions related to dysplasia. Hip dysplasia may lead to arthrosis at an early age due to poor coverage of the femoral head and abnormal loading of the joint articulation. In patients with symptomatic dysplasia and closed triradiate cartilage (generally over age 10), including adolescents and young adults (generally up to around age 40), the Bernese periacetabular osteotomy (PAO) is a durable technique for addressing underlying structural deformity. The PAO involves a modified Smith-Petersen approach. Advantages of the Bernese osteotomy include preservation of the weight-bearing posterior column of the hemi-pelvis, preservation of the acetabular blood supply, maintenance of the hip abductor musculature, and the ability to effect powerful deformity correction about an ideal center of rotation. There is an increasing body of evidence that preservation of the native hip can be improved through pelvic osteotomy. In contrast to hip osteotomy and joint preservation, the role of total hip arthroplasty in young, active patients with correctable hip deformity remains controversial. Moreover, the durability of hip replacement in young patients is inherently limited. Pelvic osteotomy should be considered the preferred method to address correctable structural deformity of the hip in the young, active patient with developmental dysplasia. The Bernese PAO is technically demanding, yet offers reproducible results with good long-term survivorship in carefully selected patients with preserved cartilage and the ability to meet the demands of rehabilitation.

  6. Hip dysplasia in a litter of Domestic Shorthair cats

    International Nuclear Information System (INIS)

    A 14-month-old female Domestic Shorthair cat was presented with bilaterally shallow acetabuli, flattened femoral heads, and subluxation of the hips, changes consistent with hip dysplasia. Follow-up radiographs showed additional osteophyte formation and remodeling of both coxofemoral joints. Two of her female littermate exhibited the same condition. Pelvic examinations of a male from the same litter as well as those of the queen and two other 3-year-old offspring were normal. This report demonstrates that it is likely that genetics plays a role in felinehip dysplasia, although further detailed reports and similar investigations of related cats affected by this condition are needed

    Full Text Available For over a decade, abduction splinting has been the method of treatment for developmental dysplasia of the hip in the Paquito González Cueto University Pediatric Hospital. This paper is aimed at presenting the dynamic classification for this condition from a radiographic point of view. Representative schemes and radiographies of patients with various stages of developmental hip dysplasia were used for illustrating this classification. The dynamic behavior of the radiographic parameters used in the classification allows gathering diagnostic groups before, during and after treatment in order to assess its final results.

    Many papers have been published about the different types of measurements used in the evaluation of hip dysplasia in the pediatric age group. However, there are no publications that deal with this topic regarding adults. The authors present an initial series of measurements of the angle of the roof of the acetabulum in 100 randomized asymptomatic adult males. The normal value ranged from -10/sup 0/ to +10/sup 0/. These measurements were correlated with those described by Wiberg. The combination of both methods yields highly reliable information in the evaluation of hip dysplasia.

    Background Treating developmental dysplasia of the hip is often challenging.The difficulties include not only the hip surgery itself but also the treatment of the associated lower-limb valgus deformity However,there have been very few studies on such deformity in patients with developmental hip dysplasia.In this study,we investigated the prevalence and severity of lower-limb valgus deformity,along with the relationship between the severity ef valgus deformity and mechanical alterations of the hip or the ipsilateral knee.Methods Two hundred and six affected lower limbs of 116 adult patients with untreated developmental dysplasia of the hip were included in the study,grouped according to the severity of hip dysplasia.Each study participant's radiographs were measured to quantitatively evaluate the mechanical axis deviation of the lower limb,and further to evaluate the prevalence and severity of the lower-limb valgus deformity.Some mechanical alterations of the hip and the ipsilateral knee were also measured on the radiographs.Results Of the affected lower limbs,14.1% had valgus deformities.Study participants with Crowe typeⅢ?hip dysplasiahad the most severe deformity and the highest prevalence of deformity.Severity of valgus deformity had a strong positive correlation with the lateral migration of the femoral head but not with the superior migration.A decreased lateral distal femoral angle contributed to the lower-limb valgus deformity,and the lateral distal femoral angle had a strong negative correlation with the severity of valgus deformity.Conclusions Hip dysplasia is commonly associated with lower-limb valgus deformity,and the severity of the lower-limb valgus deformity is mostly affected by lateral migration but not superior migration of the femoral head.The valgus deformity may originate mainly in the distal femur,in addition to the hip joint itself.These findings can be taken into account when planning to treat the patients with hip dysplasia.

    To assess the reliability of radiographic measurements in adults previously treated for developmental dysplasia of the hip (DDH) and to clarify whether these parameters differ according to position of the patient (supine versus standing). Fifty-one patients (41 females and 10 males) with 63 affected hips were included in the study. The mean follow-up period was 45 (44-49) years in the patients who had not undergone total hip replacement (THR). Anteroposterior radiographs of the pelvis were taken with the patient in the supine and in the standing position. Measurements used for residual hip dysplasia were center-edge (CE) angle and migration percentage (MP). The joint space width (JSW) was measured at three or four locations of the upper, weight-bearing part of the joint, and the shortest distance was termed the minimum joint space width (minJSW). One radiologist and one orthopaedic surgeon, each with more than 30 years of experience, independently measured the radiographic parameters. The limits of agreement (LOA) of the CE angle (mean interobserver difference {+-} 2SD) were within the range -8 to 7 . The LOA of the MP were in the range -8 to 8% and of the minJSW -0.6 to 1.1 mm. The mean differences in CE angle between supine and standing radiographs (supine - standing) ranged from -1.1 to 0.0 and the mean differences in MP between supine and standing positions were below 1%. The mean positional differences in minJSW were below 0.1 mm and were not statistically significant. The interobserver variations with regard to CE angle, MP, and minJSW were moderate, indicating that these are reliable measurements in clinical practice. Femoral head coverage and JSW did not significantly differ between supine and weight-bearing positions. (orig.)

    A fully automatic method for measuring diagnostic angles of hip dysplasia is presented. The method consists of the automatic segmentation of CT images and detection of anatomical landmarks on the femur and acetabulum. The standard angles used in the diagnosis of hip dysplasia are subsequently automatically calculated. Previous work in automating the measuring of angles required the manual segmentation or delineation of the articular joint surface. In the current work automatic segmentation is established using graph-cuts with a cost function based on a sheetness score to detect the sheet-like structure of the bone. Anatomical landmarks are subsequently detected using heuristics based on ray-tracing and the distance to the approximated acetabulur joint surface. Standard diagnositic angles are finally calculated and presented for interpretation. Experiments using 26 patients, showed a good agreement with gold standard manual measurements by an expert radiologist as performed in daily practice. The mean difference for the five angles was between -1:1 and 2:0 degrees with a concordance correlation coefficient between 0:87 and 0:93. The standard deviation varied between 2:3 and 4:1 degrees. These values correspond to values found in evaluating interobserver and intraobserver variation for manual measurements. The method can be used in clinical practice to replace the current manual measurements performed by radiologists. In the future, the method will be integrated into an intraoperative surgical guidance system.

    Full Text Available Aim: The purpose of the study was to determine the prevalence, incidence, and etiology as well as the risk factors for developmental dysplasia of the hip in newborns in whom we performed ultrasonography for screening using Graff’s method in our clinic. Methods: We retrospectively evaluated 2632 hip ultrasonography records of 1316 babies performed between 2008 and 2013. We analyzed the questionnaires of the Turkish Pediatric Orthopaedic Society which were filled by the physician during examination. The babies were divided into two groups according to ultrasonographic hip angles as pathological and normal. Results: The study is made on 1316 babies [680 girls (51.6%, 636 boys (48.4%]. The risk for developmental dysplasia of the hip was higher in girls, babies with a family history, babies with metatarsus adductus and those have been swaddled before. The mean gestational age and gestational weight was statistically significantly lower in the pathological group (p=0.0011. Conclusion: In our cross-sectional study, the incidence of developmental dysplasia of the hip was 0.5%. Female gender, positive family history of developmental dysplasia of the hip,metatarsus adductus and swaddling are still risk factors. Researching risk factors carefully, patient education and adding hip ultrasonograpy to newborn routine screening program are important measures in preventing developmental dysplasia of the hip.

    There is no consensus on the definition of dysplasia of the hip (DH). Past and present concepts used to describe DH do not form a complete view of the pathology. Moreover, some authors still present the disease as congenital, not developmental. This prompted authors to analyze the evolution of the definition of DH. Based on the biomedical databases 500 articles and books in the field of hip dysplasia were found and analyzed. Fifteen definitions of hip dysplasia met inclusion criteria, subsequently were analyzed and presented in chronological order. The analysis revealed that currently there is no single, universal definition of hip dysplasia in the aspect of morphological, clinical, and radiological studies. Despite the widely-used term of DH, it is described imprecisely and in different ways. Therefore, it is necessary to develop a multidisciplinary definition of this pathology covering all aspects of hip disorders considered valid in modern orthopaedics. PMID:26528350

  3. Delayed ossification of the femoral head in dogs with hip dysplasia

    International Nuclear Information System (INIS)

    In humans, delayed ossification of the caput femoris is often seen associated with hip dysplasia in babies. This phenomenon may possibly exist in dogs. In this study, the radiographic appearance of the caput femoris of 13 German shepherd dogs was examined. The dogs underwent pelvic radiography at the age of 14 to 15 days, six weeks, and 12 months. A significant relationship was shown between hip dysplasia and the late appearance of the epiphysis of the caput femoris (P=0–02). At the age of 14 to 15 days it was not possible to see both epiphyses in 54 per cent of the dogs. All of these dogs had hip dysplasia when they were 12 months old. This was in contrast to the six dogs which had both epiphyses visible when they were 14 to 15 days old. At 12 months of age, four of these dogs (67 per cent) did not show any sign of hip dysplasia

    Objective:To evaluate the outcome of total hip arthroplasty (THA) with cementless cups and femoral head autografts for patients with hip dysplasia and osteoarthritis.Methods: Between 1995 and 2002, we implanted 23cementless cups and femoral head autografts in 20 patients with hip dysplasia and osteoarthritis. In this study, a retrospective study was made on 21 hips in 20 patients (18females and 2 males, aged 50 years on an average) with developmental hip dysplasia treated by THA with acementless cup and femoral head autograft. The acetabular cup was placed at the level of the true acetabuinm and all the patients required autogenous femoral head grafts due to acetabular deficiency. The average rate of the acetabular cup covered by the femoral head autograft was 31%(ranging from 10% to 45%). Eight hips had less than 25%cup coverage and thirteen between 25% and 50%. The average follow-up period was 4.7 years (range, 1-8 years).The replacing outcome was evaluated by modified Harris hip score. Preoperative and follow-up radiographs were made.Results: All the autografts were united to the host bones. No autograft was collapsed or no component from the hip was loosed in all the patients. According to the modified Harris hip score, the average hip score increased from 46 before operation to 89 at the final review. Before operation, the leg-length discrepancy was greater than 2 cm in all the patients except one with bilateral hip dysplasia.After operation, only 2 out of 20 patients had a leg-length discrepancy greater than 1 cm. Three hips showed minor bone resorption in the lateral portion of the graft, which did not support the cup. Three hips developed Grade 1Brooker heterotopic ossification and one developed Grade 2.Conclusions: THA with a cementless cup and a femoral head autograft for patients with osteoarthritis resulted from hip dysplasia can result in favorable outcomes. This method can provide reliable acetabular fixation and restore the acetabular bone stock in

    Full Text Available Some orthopedic complications have been reported in the hereditary neuropathies. However, the association of the hip dysplasia with this category of neuropathy is rarely recognized. We present a 13-year-old boy with the progressive weakness of the lower extremities, difficulty in walking, climbing stairs, and rising from floor; a wide-based, hyper-extended and waddling gait similar to a myopathic process. Hip radiography showed dysplastic acetabulae with hip subluxation, broken Shenton′s lines, and valgus femoral necks. In electrodiagnosis, there was a significant neuropathic process (absent all evoked sensory potentials, abnormal evoked motor responses, and neurogenic electeromyography which eventually was found to be a hereditary mixed axonal and demyelinating sensorimotor polyneuropathy with concomitant hip dysplasia confirmed with thorough physical examination and the electrodiagnostic study. In patients with gait difficulties such as waddling gait mimicking a myopathic process, hereditary polyneuropathy complicated with hip dysplasia should be considered as well.

  8. Progression of hip dysplasia in 40 police working dogs: a retrospective study

    International Nuclear Information System (INIS)

    The aim of the study was to evaluate the effects of progression of CHD and degenerative joint disease on a working capability of population of police working dogs. In the first part of the study, we reviewed the whole health documentation of all dogs and gathered all necessary radiographs of hip joints that were taken at first initial procurement. In the second part, clinical examination and radiographs of all dogs were taken 60 months after first examination and the progression of hip dysplasia was evaluated by the FCI scheme. All dogs were male, 35 German shepherds and 5 Rottweilers. The Norberg-Olsson angle in the first set of radiographs was 105.54 +/- 3.22 deg in 37 dogs without hip dysplasia and 100.17 +/- 2.99 deg in 3 dogs with initial mild dysplasia. In the second set of radiographs taken after 60 months of service the Norberg- Olsson angle was 105.60 +/- 3.67 deg in 23 dogs with no signs of hip dysplasia and 101.62 +/- 4.49 deg in 17 dogs with hip dysplasia. On the first set of radiographs, secondary degenerative changes were found in 3 dogs with initial mild dysplasia (7.5 %) and in 14 dogs (35 %) on second radiographs. The position of the centre of the femoral head on first radiographs was outside of dorsal acetabular rim in 25 (31.25 %) of estimated hip joints (n = 80); at the level of the rim in 30 (37.5 %) and inside in 25 (31.25 %). On second radiographs it was outside in 41 (51.25 %); at the level of the rim in 26 (32.5 %); and inside in 13 (31.25 %) of estimated hip joints. The mean femoral angle of inclination for all 40 dogs was 132.50 +/- 4.39? deg . If it has occured, the increase in degree of hip dysplasia was generally more than one degree. In 57.5 % of cases hip dysplasia was not determined on second radiographs. All dogs with some degree of hip dysplasia were German shepherds, but only one of them had clinical symptoms connected to CHD. The progression of hip dysplasia did not correlate with work period of the dogs, and has no influence on

    [Purpose] To study preoperative and postoperative hip circumference data of various types of congenital dysplasia of the hip treated with total hip replacement, including the femoral offset, femoral neck length, height, and hip abductor arm parameters. [Subjects and Methods] This study included seventy-eight cases of congenital dysplasia of the hip (I-III type). Furthermore, four parameters were measured, including the preoperative and postoperative femoral offset. Statistical data analysis was performed using the SPSS 13.0 software. [Results] The femoral offset was 33.3 ± 8.4 mm (preoperative) and 39.1 ± 7.1 mm (postoperative). The femoral head height was 59.5 ± 8.7 mm (preoperative) and 68.8 ± 11.0 mm (postoperative). The femoral neck length was 50.8 ± 10.8 mm (preoperative) and 61.5 ± 10.4 mm (postoperative). The hip abductor arm was 54.3 ± 9.6 mm (preoperative) 64.7 ± 10.1 mm (postoperative). The preoperative and postoperative parameters showed statistical differences. Furthermore, no significant differences were evidenced when comparing the postoperative hip parameters with the normal data parameters. [Conclusion] Total hip replacement on congenital dysplasia of the hip could lead to the rebuilt of an almost normal physiological anatomy for each hip case (type I-III). PMID:27512242

  12. Monitoring Hip and Elbow Dysplasia achieved modest genetic improvement of 74 dog breeds over 40 years in USA.

    Full Text Available Hip (HD and Elbow Dysplasia (ED are two common complex developmental disorders of dogs. In order to decrease their prevalence and severity, the Orthopedic Foundation for Animals (OFA has a voluntary registry of canine hip and elbow conformation certified by boarded radiologists. However, the voluntarily reports have been severely biased against exposing dogs with problems, especially at beginning period. Fluctuated by additional influential factors such as age, the published raw scores barely showed trends of improvement. In this study, we used multiple-trait mixed model to simultaneously adjust these factors and incorporate pedigree to derive Estimated Breeding Values (EBV. A total of 1,264,422 dogs from 74 breeds were evaluated for EBVs from 760,455 hip scores and 135,409 elbow scores. These EBVs have substantially recovered the reporting bias and the other influences. Clear and steady trends of genetic improvement were observed over the 40 years since 1970. The total genetic improvements were 16.4% and 1.1% of the phenotypic standard deviation for HD and ED, respectively. The incidences of dysplasia were 0.83% and 2.08%, and the heritabilities were estimated as 0.22 and 0.17 for hip and elbow scores, respectively. The genetic correlation between them was 0.12. We conclude that EBV is more effective than reporting raw phenotype. The weak genetic correlation suggested that selection based on hip scores would also slightly improve elbow scores but it is necessary to allocate effort toward improvement of elbow scores alone.

    BACKGROUND: A neonatal screening programme for developmental dysplasia of the hip (DDH) is ongoing in Cork. Despite early screening, infants continue to present at later ages with DDH. The impact of late diagnosis is significant. Established DDH causes significant morbidity and may have major medicolegal implications. AIM: To identify the reasons for the late presentation of DDH in the presence of a screening programme. METHODS: In a retrospective study all cases of late DDH presenting from 1988 to 2000 were identified using inpatient database. RESULTS: Forty-nine cases of DDH were diagnosed. The mean age of diagnosis was 14.8 months (range 6-47). Multiple risk factors were identified in four patients only. More than one risk factor was identified in 10 patients. CONCLUSION: Despite screening, children continue to present with late DDH. In this study, only 14 patients had multiple risk factors and only four patients had more than two risk factors, highlighting the low incidence of suspicion in this patient group.

    2008-01-01

    Background Recently, the new generation of metal-on-metal total hip resurfacing arthroplasty is well known for preserving the proximal femoral bone stock, minimizing the risk of postoperative dislocation using large femoral heads, and expecting low wear of metal-on-metal articulation for longer prosthesis survival. It also has the advantage in biomechanical loading in the proximal femur. The osteoarthritis secondary to developmental dysplasia of the hip (DDH) has been the most common reason for total hip arthroplasty. Most of the patients are young and active, who require improved range of motion of the hip besides relief of the pain, even expect to resume the ability to run and jump after the joint arthroplasty, thus to be allowed an active lifestyle. The objective of the current study was to evaluate the early outcome of resurfacing arthroplasty for the mild DDH cases (Crowe type Ⅰ and Ⅱ).Methods Between September 2005 and May 2007, twenty-one consecutive patients (twenty-six hips) with the diagnosis of osteoarthritis secondary to DDH underwent metal-on-metal resurfacing arthroplasty. The average age at the time of surgery was 46.5 years (range, 37-59 years). Six patients (28.6%) were male and fifteen (71.4%) were female. Clinical and radiographic results were observed. The follow-up was performed at 6 weeks, 3, 6, 9 months and then yearly.Results All patients were followed for a mean of 18 months (9-29 months). During the follow-up period no complications, such as dislocation of hip joints, infection or femoral neck fracture occurred. The clinical outcomes, as rated with the Harris hip score, improved significantly compared with the preoperative ratings. The mean postoperative Harris hip score was 90.7, compared to 35.5 preoperatively. The radiographic analysis showed that all prostheses were fixed with no radiolucencies. All of the patients who had equal limb lengths preoperatively had equal lengths postoperatively. Of the nine patients with preoperative

    Full Text Available Stem cells isolated from adipose tissue show great therapeutic potential in veterinary medicine, but some points such as the use of fresh or cultured cells and route of administration need better knowledge. This study aimed to evaluate the effect of autologous stromal vascular fraction (SVF, n=4 or allogeneic cultured adipose-derived stem cells (ASCs, n=5 injected into acupuncture points in dogs with hip dysplasia and weak response to drug therapy. Canine ASCs have proliferation and differentiation potential similar to ASCs from other species. After the first week of treatment, clinical evaluation showed marked improvement compared with baseline results in all patients treated with autologous SVF and three of the dogs treated with allogeneic ASCs. On days 15 and 30, all dogs showed improvement in range of motion, lameness at trot, and pain on manipulation of the joints, except for one ASC-treated patient. Positive results were more clearly seen in the SVF-treated group. These results show that autologous SVF or allogeneic ASCs can be safely used in acupoint injection for treating hip dysplasia in dogs and represent an important therapeutic alternative for this type of pathology. Further studies are necessary to assess a possible advantage of SVF cells in treating joint diseases.

    Full Text Available Abstract Background The gluteus medius muscle is essential for gait and hip stability. Changes that occur in the gluteus medius muscles in patients with developmental dysplasia of the hip (DDH are not well understood. A better understanding of DDH related changes will have positive repercussions toward hip soft tissue reconstruction. Methods 19 adult patients with unilateral DDH scheduled for total hip arthroplasty were assessed for: cross-sectional area (CSA, radiological density (RD and the length of gluteus medius using computed tomograhpy(CT (scanned before THA. Hip abductor moment arm and gluteus medius activation angle were also measured via hip anteroposterior radiographs. Results Both CSA and RD of gluteus medius muscle were significantly reduced (p  Conclusions The gluteus medius showed substantial loss of CSA, RD as well as decreased length in patients with DDH in the affected hip. These changes should be considered in both hip reconstruction and postoperative rehabilitation training in patients with DDH.

    A lot of methods of measurement have been developed to record precisely the degrees of luxation and the deviations from the normal form in the hip joints of the child and adult. The orthopaedic surgeon needs those data for a preoperative ''coxometric program'' before performing acetabuloplastic operations with osteotomia, osteotomia of the pelvis and combined operations. Computed tomography yields a series of informations and of possibilities of measurements which can determine the operative procedure in particular. These informations concern among other things the dimensions of the dysplasia of the acetabulum in the horizontal plane with the extension of the posterior lip and the angle of the acetabular opening, furthermore the physiological or pathological congruence between the head of the femur and the acetabulum, the angle of antetorsion of the neck of the femur and, in the small infant, the direct noninvasive imaging of the tube of the capsule with imaging of possible obstacles to reposition.

    Background: Total hip arthroplasty (THA) in developmental dysplasia of the hip (DDH) is more complex than the normal hip, with large replacement risks and many complications.Although nonosteotomy THA is convenient to perform, femoral osteotomy shortening can avoid blood vessel and nerve traction injuries.This study aimed to compare osteotomy THA with nonosteotomy to determine reasonable options for operative management of DDH.Methods: Data on 48 DDH patients who underwent THA were analyzed retrospectively.The patients were divided into two groups: Group A 29 cases (nonosteotomy), and group B 19 cases (osteotomy).Harris and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, limb length discrepancy (LLD), radiological data on the hip, and claudication were evaluated.Data were analyzed by using paired-sample Student's t-test, independent-sample Student's t-test, and Pearson's Chi-square test;the test level was α =0.05.Results: Postoperative Harris (90.7 ± 5.1) and WOMAC scores (88.0 ± 10.6) were significantly improved compared with preoperative Harris (44.8 ± 5.7) and WOMAC scores (42.0 ± 5.3) in group A (P < 0.05).Postoperative Harris (90.4 ± 2.8) and WOMAC scores (88.2 ± 5.9) were significantly improved compared with preoperative Harris (44.4 ± 4.2) and WOMAC scores (43.2 ± 4.3) in group B (P < 0.05).One case of dislocation occurred in group A;after closed reduction, dislocation did not recur.In group A, 2 patients developed cutaneous branch injury of the femoral nerve, which spontaneously recovered without treatment.Postoperative LLD >2 cm was seen in one case in group A and five cases in group B.Postoperative claudication showed no significant difference between the two groups (P > 0.05).No patients developed infection;postoperative X-rays showed that the location of the prosthesis was satisfactory, and the surrounding bone was not dissolved.Conclusions: THA is effective and safe for DDH.For unilateral high dislocation

    2016-01-01

    Background Developmental dysplasia of the hip joint is one of the most common congenital defects and often results in functional and structural disorders. Such cases particularly demand optimizing therapeutic effects and maximally reducing the duration of therapy. Purpose The aim of this case report is to present the therapeutic process in a child with developmental hip dysplasia. Case report This is a case report of a female child with a birth weight of 2,800 g and an Apgar score of 9 points born to a gravida 3 para 3 mother at 37 weeks. The child was delivered by cesarean section, and the pregnancy was complicated by oligohydramnios. Subluxation of the left hip joint was diagnosed by an orthopedist in the third month of life. The treatment followed was the Vojta method (the first phase of reflex turning and reflex crawling). Results During the 6 weeks of the Vojta treatment, the left half of the femoral head was centralized, and the process of formation of the hip joint acetabulum was influenced effectively enough to change the acetabulum’s Graff type from the baseline D to IIb after 41 days of treatment. Conclusion The diagnostic work-up of congenital hip joint dysplasia should involve a physiotherapist who will investigate the child’s neuromuscular coordination, in addition to a neonatologist and a pediatrician. The therapy for a disorder of hip joint development of neuromotor origin should involve the application of global patterns according to Vojta. Children with congenital dysplasia of the hip joint should commence rehabilitation as early as possible. PMID:27578980

    Full Text Available BACKGROUND: In Mongolia, adequate early diagnosis and treatment of developmental hip dysplasia (DDH have been unavailable and its incidence was unknown. We determined the incidence of ultrasonographic DDH in newborns and established adequate procedures for diagnosis and treatment of DDH at the largest maternity hospital in Ulaanbaatar, Mongolia. METHODOLOGY/PRINCIPAL FINDINGS: During one year (Sept 2010 - Aug 2011 we assessed the hips newborns using ultrasound and Graf's classification of DDH. 8,356 newborns were screened; median age at screening was 1 day. We identified 14,873 Type 1 (89.0%, 1715 Type 2a (10.3%, 36 Type 2c (0.2%, 70 Type D (0.4%, 14 Type 3 (0.08%, and 4 Type 4 hips (0.02%. Children with Type 1 hips (normal were discharged. Children with Type 2a hips (physiologically immature received follow-up ultrasounds at monthly intervals. Children with Type 2c to 4 (DDH; deformed or misaligned hip joint hips were treated with a Tubingen hip flexion splint and also followed up. The hip abnormalities resolved to mature hips in all children who were followed up. There was no evidence for severe treatment related complications. CONCLUSION/SIGNIFICANCE: This study suggests that the incidence of DDH in Mongolian neonates is comparable to that in neonates in Europe. Early ultrasound-based assessment and splinting treatment of DDH led to mature hips in all children followed up. Procedures are feasible and will be continued.

    Developmental dysplasia of the hip (DDH) is a spectrum of disorders affecting the proximal femur and/or acetabulum leading to an abnormal formation of the hip. Genetic factors are involved in the etiology of DDH. Early recognition of DDH affords the best results from treatment and a better knowledge of the genetics of DDH could enhance early diagnosis. Variants in the Type II collagen (COL2A1) and vitamin D receptor (VDR) genes have been associated with patients with osteoarthritis of the hip...

    Objective: To evaluate the clinical and radiological medium-term results from surgical treatment of developmental hip dysplasia through Salter innominate bone osteotomy and Ombrédanne femoral shortening. Methods: Fourteen patients were evaluated, with surgical treatment on 18 hips (seven right-side hips and eleven left-side hips) using the proposal technique, performed between 1998 and 2008. The Dutoit and Severin criteria were used respectively for clinical and radiographic evaluations. Results: The average preoperative index for the seven right-side hips was 43.3° (40° to 50°), and this was corrected through surgery to an average of 31.57° (24° to 42°). The average preoperative index for the eleven left-side hips was 42.1° (36° to 56°), and this was corrected through surgery to an average of 30.36° (20° to 44°). There was a statistically significant difference between the preoperative and postoperative acetabular indexes, with P > 0.05. The clinical evaluation showed that there were seven excellent hips (38.9%), eight good ones (44.4%), three fair hips (16.7%) and no poor ones (0%). By grouping the hips rated good and excellent as satisfactory and those rated poor and fair as unsatisfactory, 83.3% of the results were seen to be favorable. There were no statistically significant correlations between occurrences of complications and patient age at the time of surgery or between complications and the preoperative acetabular index (p > 0.05). The complications observed consisted of one case each of subluxation, osteonecrosis and osteonecrosis together with subluxation. Conclusion: The combined procedure of Salter and Ombrédanne is a viable option for treating developmental hip dysplasia after patients have started to walk. PMID:27027068

    Full Text Available Sacral agenesis (SA is a rare condition consisting of the imperfect development of any part of the sacrum. This paper describes two cases of the rare cooccurrence of ipsilateral SA and developmental dysplasia of the hip (DDH and analyzes possible contributory factors for SA and DDH. Each of a 16-year-old female and 13-year-old female visited our hospital for left hip pain and limping. The findings of physical examinations showed a lower limb length discrepancy (left side in both cases, as well as left hip pain without limitations of the range of motion or neurological deficits. Initial radiographs demonstrated left subluxation of the left hip with associated acetabular dysplasia and partial left sacral agenesis. MRI revealed a tethering cord with a fatty filum terminale, and periacetabular osteotomy combined with allogeneic bone grafting was performed. After the surgery, the patients experienced no further pain, with no leg length discrepancy and were able to walk without a limp, being neurologically normal with a normal left hip range of motion. The cooccurrence of SA and DDH suggests a plausible hypothesis to explain the embryogenic relationship between malformation of the sacrum and hip.

    Full Text Available Developmental dysplasia of the hip (DDH is one of the most widely discussed abnormalities in neonates. The advantages of sonographic examination are well known, but its main disadvantage is that it might lead to over diagnosis, which might cause over treatment. Variations in the incidence of developmental dysplasia of the hip are well known. During six months study since September 2006 all 1300 neonates (2600 hips were born in our hospital examined clinically and sonographically (587 hips in the first 48 hours of life. Sonography was performed according to Graf's method, which considers mild hip sonographic abnormalities as type II a. Type IIb Graf were considered pathologic. Sonography screening of 587 hips detected 36 instances of deviation from normal indicating a sonographic DDH incidence of 12.5%. However, only 8 neonates remained abnormal and required treatment, indicating a true DDH incidence of 6 per 1000 live birth. Risk of diagnosis clinically and sonographicaly were 2.5 and 4.5 percent respectively and was significant (P<0.00001, x2=1170. In order to avoid over diagnosis in first days examination, repeated clinical and sonographic examination is required.

    Measurements of length and breadth were done in 439 X-ray pictures of the pelvis of German Shepherd Dog, Rottweiler and Great Dane. The relation of pelvic proportions to hip dysplasia was checked. In 66 X-ray pictures of the pelvis of young dogs the ischiadic part of the acetabulum was measured. In all breeds the ischium formed 68,8 percent of the acetabulum. Ilium and ischium showed changes in relation to hip dysplasia, which could be proved unequivocally only in Rottweilers. Changes of pelvic proportions in other breeds were not perceived. In Rottweilers also those changes can be seen distinctly only in severe cases of hip dysplasia. For the special case valid accordance with any degree of hip dysplasia could not be found.

    The use of MRI scanning has been described after open reduction of the hip in developmental dysplasia of the hip (DDH) to check hip position, but has not previously been reported after open reduction with femoral osteotomy and the use of metalwork. We report a prospective study to determine whether MRI scanning can be used to confirm satisfactory reduction of the hip following surgery for DDH, even in the presence of metalwork in the proximal femur. MRI scans were performed in 12 consecutive children, and all gave diagnostic information indicating satisfactory reduction. Sedation was not required and the mean scanning time was 3 min 45 s. Satisfactory images, the lack of need for sedation, comparable time and cost to CT scanning and most importantly the lack of exposure of the child to ionizing radiation make MRI a most appealing method for imaging. We therefore recommend it as the investigation of choice in this patient group. (orig.)

    Twenty-four infants and children aged five days to three years had their hips examined by ultrasound, and in 17 the findings were compared with the radiographic appearances. Real-time sonography, because of its flexibility, is a suitable screening method for the early diagnosis of hip dysplasia. It has the typical characteristics of a screening method: so far there have been no false negative findings. False positive results are rare, but cannot be completely excluded. The patients examined so far were mostly abnormal, and a final assessment of false positive findings will have to await larger clinical material, including normals. 6 figs.

    In the field of hip arthroplasties, the secondary fixation of the implants depends directly on the quality of the primary stability. A good acetabular fit and metaphyseal filling between the prostheses and implants improve the initial stabilization, and optimize the transmission of forces to the bone. A precise knowledge of the three-dimensional acetabular or femoral shape is essential to the selection of adapted implants. A total of 63 patients diagnosed with developmental dysplasia were ana...

    OBJECTIVE: To ascertain the current approach to screen for developmental dysplasia of the hip in the Republic of Ireland. METHODS: Two-pronged prospective and retrospective study. (1) Postal questionnaire to consultant paediatricians responsible for the routine neonatal care of infants in the Irish Republic in June 2006. (2) Retrospective database review to identify infants undergoing radiological follow-up and their outcome. RESULTS: All maternity units surveyed responded. Most units (84%) were dependent on radiographs at 4-6 months for imaging hips, only two units primarily used ultrasound (10.5%). We estimate that neonatal hip examination is performed by an experienced examiner in less than 30% of routine newborn examinations. On retrospective analysis, 94% of radiographs performed were normal. CONCLUSIONS: The most effective interventions, selective ultrasound and examination by an experienced clinician are not widely practiced. There is a need for the development of national guidelines based on available resources.

    Full Text Available We carried out a cross-sectional study to measure the association of the seven acetabular parameters with pelvic morphometry and prevalence of hip dysplasia in our population. Convenience sampling was carried out and 250 consecutive patients who came to AKUH for intravenous pyelogram and had no complaints in the region of the hip joint were enrolled in the study. Post-micturition standardized plain antero-posterior pelvic radiographs of 250 asymptomatic adults (500 hip joints was studied. There were 136 males (54.4% and 114 females (45.6%. Mean age of our study population was 38 years (15-78 years. The average center edge angle was 35.5±6.6° standard deviation (SD, acetabular angle was 37.76±4.37°, depth to width ratio was 0.31±4.6°, roof obliquity was 10.6±6.2°, extrusion index was 0.1±5.8, lateral subluxation 8.9±2.7 mm, and peak to edge distance 17±3.98 mm. There was significant influence (p lower than  0.05 of age in all angles except depth to width ratio. A total of seven hip joints (1.4% were dysplastic with CE angle lower than 25° while four of the seven hips were severely dysplastic with CE angle  lower than 20°. In the dysplastic group there was significant correlation (p lower than 0.05 of CE angle with acetabular angle, depth to width ratio, extrusion index and peak to edge distance. Prevalence of hip dysplasia was found to be very low in our population. These results are consistent with the findings of studies carried out in other Asian countries.

    To report on intra-observer, inter-observer, and inter-method reliability and agreement for radiological measurements used in the diagnosis of hip dysplasia at skeletal maturity, as obtained by a manual and a digital measurement technique. Pelvic radiographs from 95 participants (56 females) in a follow-up hip study of 18- to 19-year-old patients were included. Eleven radiological measurements relevant for hip dysplasia (Sharp's, Wiberg's, and Ogata's angles; acetabular roof angle of Toennis; articulo-trochanteric distance; acetabular depth-width ratio; femoral head extrusion index; maximum teardrop width; and the joint space width in three different locations) were validated. Three observers measured the radiographs using both a digital measurement program and manually in AgfaWeb1000. Inter-method and inter- and intra-observer agreement were analyzed using the mean differences between the readings/readers, establishing the 95% limits of agreement. We also calculated the minimum detectable change and the intra-class correlation coefficient. Large variations among different radiological measurements were demonstrated. However, the variation was not related to the use of either the manual or digital measurement technique. For measurements with greater absolute values (Sharp's angle, femoral head extrusion index, and acetabular depth-width ratio) the inter- and intra-observer and inter-method agreements were better as compared to measurements with lower absolute values (acetabular roof angle, teardrop and joint space width). The inter- and intra-observer variation differs notably across different radiological measurements relevant for hip dysplasia at skeletal maturity, a fact that should be taken into account in clinical practice. The agreement between the manual and digital methods is good. (orig.)

    To report on intra-observer, inter-observer, and inter-method reliability and agreement for radiological measurements used in the diagnosis of hip dysplasia at skeletal maturity, as obtained by a manual and a digital measurement technique. Pelvic radiographs from 95 participants (56 females) in a follow-up hip study of 18- to 19-year-old patients were included. Eleven radiological measurements relevant for hip dysplasia (Sharp's, Wiberg's, and Ogata's angles; acetabular roof angle of Toennis; articulo-trochanteric distance; acetabular depth-width ratio; femoral head extrusion index; maximum teardrop width; and the joint space width in three different locations) were validated. Three observers measured the radiographs using both a digital measurement program and manually in AgfaWeb1000. Inter-method and inter- and intra-observer agreement were analyzed using the mean differences between the readings/readers, establishing the 95% limits of agreement. We also calculated the minimum detectable change and the intra-class correlation coefficient. Large variations among different radiological measurements were demonstrated. However, the variation was not related to the use of either the manual or digital measurement technique. For measurements with greater absolute values (Sharp's angle, femoral head extrusion index, and acetabular depth-width ratio) the inter- and intra-observer and inter-method agreements were better as compared to measurements with lower absolute values (acetabular roof angle, teardrop and joint space width). The inter- and intra-observer variation differs notably across different radiological measurements relevant for hip dysplasia at skeletal maturity, a fact that should be taken into account in clinical practice. The agreement between the manual and digital methods is good. (orig.)

    Full Text Available An Alaskan Malamute (2-year-old, castrated male, 41kg was referred with bilateral hind limb lameness. The dog had a history of a bilateral triple pelvic osteotomy (TPO to correct hip dysplasia one year previously, a surgery that was unsuccessful. On physical examination, pain and crepitus were noted in both hip joints. There was hip joint subluxation and mild degenerative changes bilaterally seen by radiograph. A Zurich cementless total hip replacement (ZCTHR was planned for the right hind limb. After a craniolateral approach, an acetabular cup and a cementless femoral stem were implanted. The femoral head was placed in the femoral stem, and the prosthetic joint was then reduced. At a 9 month postoperative checkup, there was no pain on palpation or manipulation of the right pelvic limb, and the range of motion was within normal limits. On radiological examination, there was no implant loosening. The ZCTHR can thus be applied in a failed TPO patient as a revision surgery.

    In order to determine the prevalence of hip dysplasia (HD) from radiographs that were submitted for authorative grading, and its changes over the time in 31 breeds of dogs in France, a 14 year-retrospective study was conducted. Significant differences were observed between breeds, with HD prevalence ranging from 59.7% (Cane Corso) to 3.9% (Siberian Husky). When comparing the 1993-1999 with the 2000-2006 period in 15 breeds, a significant decrease in HD prevalence was detected in Berger Picard, Bernese Mountain dog, Briard, Gordon Setter, White Swiss Sheepdog and Rottweiler. Modifications observed in the other breeds were not statistically significant. PMID:18288340

    Joint morphogenesis is an important phase of prenatal joint development during which the opposing cartilaginous rudiments acquire their reciprocal and interlocking shapes. At an early stage of development, the prenatal hip joint is formed of a deep acetabular cavity that almost totally encloses the head. By the time of birth, the acetabulum has become shallower and the femoral head has lost substantial sphericity, reducing joint coverage and stability. In this study, we use a dynamic mechanobiological simulation to explore the effects of normal (symmetric), reduced and abnormal (asymmetric) prenatal movements on hip joint shape, to understand their importance for postnatal skeletal malformations such as developmental dysplasia of the hip (DDH). We successfully predict the physiological trends of decreasing sphericity and acetabular coverage of the femoral head during fetal development. We show that a full range of symmetric movements helps to maintain some of the acetabular depth and femoral head sphericity, while reduced or absent movements can lead to decreased sphericity and acetabular coverage of the femoral head. When an abnormal movement pattern was applied, a deformed joint shape was predicted, with an opened asymmetric acetabulum and the onset of a malformed femoral head. This study provides evidence for the importance of fetal movements in the prevention and manifestation of congenital musculoskeletal disorders such as DDH. PMID:26163754

    Materials and Methods: 35 children with unilateral DDH were operated between 2002 and 2007 at our institute. Open reduction was performed in all using the standard anterior approach and peroperative test for hip stability was done. Nine children got an additional pelvic procedure in the form of Dega acetabuloplasty. All were followed up for a minimal period of 2 years (range 2-7 years. Results: No hip got redislocated. At the end of 18 months, there were seven cases of RAD with acetabular index (AI of 35° and above. These were all from the group where open reduction alone was done. Conclusion: We feel that a preoperative AI of >40° and a per-operative safe-zone <20° increases the need for supplementary pelvic osteotomy in age group of 18 to 24 months because in such cases, the remodeling capacity of the acetabulum is unable to overcome the dysplasia and to form a relatively normal acetabulum.

    Full Text Available Introduction. Nowadays, the total hip arthroplasty is a very frequent surgical intervention. In some cases, vascular and nerve injuries may happen around the hip with total hip arthroplasty. Although they are very rare, they may be very dangerous for the patient in some cases. This paper presents a case of a female patient, in whom the nervous fibularis lesion was detected after the total hip arthroplasty, and the occlusion of the iliac femoral artery was revealed later during physical therapy. Case Report. We described a case of a 32-year-old female patient, in whom the nervous fibularis lesion was detected after the total hip arthroplasty. The patient was referred to a ward for physical therapy. On the 19th postoperative day, she felt a vigorous ache and numbness on the left operated leg during stimulation of the paretic fibular musculature. Clinically weak inguinal arterial pulse was detected. After the examination, iliac-femoral occlusion was diagnosed. The patient was referred to the vascular surgeon. In the next few months, she was treated conservatively and eventually underwent surgery. The revascularization was achieved with a satisfactory effect. A year after the total hip replacement, the patient continued with rehabilitation and physical treatment, which lasted one and a half month and had an incomplete functional result - the patient walked with a walking stick and had weak fibular musculature of a severe degree. The vascular status of the leg was good. Conclusion. In this case, neurovascular lesions led to an incomplete functional recovery of the patient and compromised the expected treatment outcome. According to the scoring system used to assess the functionality, the result was marked as poor.

    Full Text Available Background: Developmental dysplasia of hip (DDH is one of the congenital anomalies in newborns that if not diagnosed and treated on time can lead to a severe disability. Although clinical examination is a very useful way for screening, but in some patients, a confirmatory diagnostic method such as ultrasonography is needed. The aim of the present study is to compare the sensitivity and specificity of clinical examination and ultrasonography in early detecting of DDH. Materials and Methods: A total of 5800 of newborns were examined by orthopedic surgeon as a screening method. The newborns with risk factors or suspicious on clinical examination were introduced to repeat clinical and ultrasonographic examination of hip. The results were collected and recorded by a check list and then the sensitivity and specificity of clinical examination were calculated. Results: Of 5701 newborns (11402 hips who were studied by two methods of clinical examination and ultrasonography (by Graf method, the overall incidence of DDH was 29 per 1000. Only 94 hips (13.5% of 694 disordered ones according to clinical examination were involved on ultrasonographic evaluation. A total of 240 hips of 334 (72% involved hips according to ultrasonography (Graf type IIb or more were diagnosed normal on clinical examination, considering ultrasonography as a gold standard method of evaluating DDH, the sensitivity and specificity of clinical examination were calculated 28.1% and 94.5%, respectively. Conclusion: According to the present study, ultrasonogeraphic examination has a high valuable in screening of DDH and the clinical examination done by an experienced orthopedic surgeon has an acceptable value in primary screening of DDH in developing countries for detecting of healthy neonates, but if the newborn has a risk factor or is suspicious on clinical examination, it will be necessary to get assistance from ultrasonography by an experienced sonographer.

    Developmental dysplasia of the hip is a congenital hip joint malformation affecting the proximal femurs and acetabulum that are subluxatable, dislocatable, and dislocated. Conventionally, physicians made diagnoses and treatments only based on findings from two-dimensional (2D) images by manually calculating clinic parameters. However, anatomical complexity of the disease and the limitation of current standard procedures make accurate diagnosis quite difficultly. In this study, we developed a system that provides quantitative measurement of 3D clinical indexes based on computed tomography (CT) images. To extract bone structure from surrounding tissues more accurately, the system firstly segments the bone using a knowledge-based fuzzy clustering method, which is formulated by modifying the objective function of the standard fuzzy c-means algorithm with additive adaptation penalty. The second part of the system calculates automatically the clinical indexes, which are extended from 2D to 3D for accurate description of spatial relationship between femurs and acetabulum. To evaluate the system performance, experimental study based on 22 patients with unilateral or bilateral affected hip was performed. The results of 3D acetabulum index (AI) automatically provided by the system were validated by comparison with 2D results measured by surgeons manually. The correlation between the two results was found to be 0.622 (p<0.01).

    Full Text Available This paper aimed to assess the prevalence of hip dysplasia (HD in some breeds of dogs widely diffused in Italy and to estimate heritability of HD in German Shepherd and Boxer Italian populations. Data consisted of radiographic findings taken on 32,900 dogs (18,665 females and 14,225 males of 7 breeds (German Shepherd; Boxer; Labrador Retriever; Golden Retriever; Rottweiler; Dobermann; Cane Corso screened at an age of 17.9 ± 7.0 months. Radiographs of the coxofemoral joints, taken by 478 veterinarians, were scored for HD grade by a single veterinarian panelist according to a grading procedure based on a 5-class linear system (from A, no signs of dysplasia, to E, severe dysplastic hip changes. Logistic regression analysis was used for studying the relationships between selected explanatory variables with the out- come of the diagnosis for HD. Variance components, direct and maternal heritability have been estimated for German Shepherd and Boxer dogs using a REML animal model procedure. Prevalence of HD (hip joint graded C or worse for the pool of breeds involved approached 22%, with large differences among breeds. In dogs diagnosed as dysplastic, the mild form (grade C was largely prevalent for all breeds. When compared to the German Shepherd, the Cane Corso exhibit- ed a significantly higher risk, whereas the Dobermann, Labrador and Rottweiler showed a significantly lower risk of being affected by HD. The probability of being diagnosed as dysplastic increased with the increasing of the age of dogs at screening and with the decreasing of experience of x-raying veterinarians. The effect of birth year of dogs on the out- come of the HD diagnosis was significant, but evidenced an inconsistent trend through years. Heritability estimates approached 0.24 and 0.15 for Boxers and German Shepherds, respectively, whereas maternal heritability was close to 0.03 for both breeds. Results from this study demonstrated that HD is fairly prevalent in some breeds

A incidência da DDQ é variável, dependendo de vários fatores, inclusive da localização geográfica. Aproximadamente um em cada 1.000 recém-nascidos poderá nascer com o quadril luxado e cerca de 10 em 1.000 com o quadril subluxado (instável. Em nosso meio podemos esperar a incidência de cinco por 1.000 quanto à positividade do sinal de Ortolani, que é o sinal clínico precoce de detecção da afecção. Os fatores de risco para a DDQ incluem: sexo feminino, raça branca, primiparidade, mãe jovem, apresentação pélvica ao nascimento, história familiar, oligohidrâmnio, recém-nascido com maiores peso e altura e com deformidades nos pés ou na coluna vertebral. O exame do quadril do recém-nascido deverá ser rotineiro e enfatizado nos berçários. No recém-nascido e nos bebês o diagnóstico da DDQ é eminentemente clínico e realizado com as manobras de Ortolani e de Barlow.

  1. Shielding during x-ray examination of pediatric female patients with developmental dysplasia of the hip

    International Nuclear Information System (INIS)

    Patients with developmental dysplasia of the hip (DDH) generally undergo multiple x-ray examinations of both hip joints. During these examinations, the gonads are completely exposed to radiation, unless shielded. Although many types and sizes of gonad shields exist, they often do not provide adequate protection because of size and placement issues; additionally, these shields are frequently omitted for female patients. Our aim was to assess gonad protection during x-ray examination that is provided by gonad shields designed for individual female patients with DDH. We retrospectively retrieved data from the Picture Archiving and Communication System database; pelvic plain x-ray films from 766 females, 18 years old or younger, were included in our analysis. Based on x-ray measurements of the anterior superior iliac spine, we developed a system of gonad shield design that depended on the distance between anterior superior iliac spine markers. We custom-made shields and then examined shielding rates and shielding accuracy before and after these new shields became available. Standard (general-purpose) shields were used before our custom design project was implemented. The shielding rate and shielding accuracy were, respectively, 14.5% and 8.4% before the project was implemented and 72.7% and 32.2% after it was implemented. A shield that is more anatomically correct and available in several different sizes may increase the likelihood of gonad protection during pelvic x-ray examinations. (paper)

    Full Text Available We report the case of a 72-year-old woman whose pseudoaneurysm was difficult to diagnose and treat. The patient had a history of congenital dislocated hip and was undergoing anticoagulation therapy with warfarin due to the mitral valve replacement. Her chief complaint was pain and enlargement of the left buttock, and the laboratory tests revealed severe anemia. However, her elderly depression confused her chief complaint, and she was transferred to a psychiatric hospital. Two months after the onset of the symptoms, she was finally diagnosed with a pseudoaneurysm by contrast-enhanced CT and angiography. IDC coils were used for embolization. A plain CT showed hemostasis as well as a reduced hematoma at 2 months after the embolization. The possible contributing factors for the pseudoaneurysm included bleeding due to warfarin combined with an intramuscular hematoma accompanied by Crowe type IV developmental dysplasia of the hip that led to an arterial rupture by impingement between pelvis and femoral head. Since the warfarin treatment could not be halted due to the valve replacement, embolization was chosen for her treatment, and the treatment outcome was favorable.

    Previous reports demonstrated 8-60% patients treated for developmental dislocation of hip (DDH) in infancy have residual acetabular dysplasia (AD) at skeletal maturity. AD patients reportedly exhibit abnormal morphology of the pelvis, high rates of comorbid spinal congenital anomalies and high bone mineral density. These physical findings suggest that AD patients have genetic background. We examined the percentage of AD patients with hip pain at skeletal maturity having a history of DDH in infancy and the correlation between the severity of AD at skeletal maturity and history of DDH treatment to investigate the relationship between AD and DDH.A total of 245 patients were radiographically examined for any history of DDH treatment in infancy. The study included 226 women and 19 men with a mean age at examination of 40.7 years (range 17-59 years).Eighty-eight patients (36%) had a history of DDH treatment (DDH group) and the remaining 157 patients (64%) had no history of DDH treatment (non-DDH group). The average age was lower and acetabular angle was larger in the DDH group. There was a significant increasing trend of the percentage of DDH patients associated with the severity of AD classified with CE, acetabular angle, and acetabular roof angle.Our data suggest that there are several AD patients without a history of DDH in Japan, and AD in patients without a history of DDH has different characteristics from AD in patients with a history of DDH.

    Full Text Available DDH includes a spectrum of disorders affecting a developing hip joint, varying from an occult dysplasia to frank dislocation. Since the hip joint at birth is purely cartilaginous the chances of missing this condition is very high. High degree of suspicion is essential to make sure that cases are detected early. Difficulty in changing the diapers may be any early indicator of occult dysplasia.

    Full Text Available Introduction. Developmental dysplasia of the hip (DDH represents one of common diseases of the locomotor system. Late discovery and inadequate healing of this defect leads to serious disability in the best years of human life. Objective. The aim of this study was to analyze the quality of functional and anatomic restitution of the diseased hip, depending on the age of the patient at the time of surgery. Methods. Our retrospective study was developed on 78 children surgically treated for DDH. The examiners were distributed in three groups according to age in which they had been operated. The data were produced on the basis of full-scale medical documents for each patient. Results. We analyzed and compared anatomic and functional results of surgeries treating DDH in the group of examiners. On examination, we got data that the most prevalent were distorted gait, inequality of the legs and positive Trendelendburg’s sign in the group of children who had been operated in the oldest age. The patients who were surgically treated in older age had worse postoperative results in aspect value angle of flexion and abduction in treated hip, higher frequency in manifesting pain and asymmetric gait. Better corrective results on aspect of dimension of the colodiaphyseal and Hilgenrainer’s angle will be obtained if DDH treatment is conducted in younger age of patients. In 94.95%, the patients were treated with Salter innominate osteotomy of pelvis with osteotomy of the femur involving its shortening and reverse rotation. Preoperative treatment with Pavliks harness was provided in 44.02% children, with abduction of Hilgenrainer’s apparatus in 2.6%, with abductions “Niva” slips in 2.6% and preoperative extension in 28.2%. Conclusion. The surgical treatment of DDH in the observed patients done at the earlier age of growth resulted in the evidently better anatomical and functional results at postoperative observation.

    Developmental dysplasia of the hip (DDH) should be diagnosed as early as possible to optimise treatment. The current United Kingdom recommendations for the selective screening of DDH include a clinical examination at birth and at six weeks. In Northern Ireland babies continue to have an assessment by a health visitor at four months of age. As we continue to see late presentations of DDH, beyond one year of age, we hypothesised that a proportion had missed an opportunity for earlier diagnosis. We expect those who presented to our service with Tonnis grade III or IV hips and decreased abduction would have had clinical signs at their earlier assessments. We performed a retrospective review of all patients born in Northern Ireland between 2008 and 2010 who were diagnosed with DDH after their first birthday. There were 75 856 live births during the study period of whom 645 children were treated for DDH (8.5 per 1000). The minimum follow-up of our cohort from birth, to detect late presentation, was four years and six months. Of these, 32 children (33 hips) were diagnosed after their first birthday (0.42 per 1000). With optimum application of our selective screening programme 21 (65.6%) of these children had the potential for an earlier diagnosis, which would have reduced the incidence of late diagnosis to 0.14 per 1000. As we saw a peak in diagnosis between three and five months our findings support the continuation of the four month health visitor check.

    Five patients with cerebral palsy, hip dysplasia, pelvic obliquity, and scoliosis were evaluated retrospectively using three dimensional computed tomography (3DCT) scans of the proximal femur, pelvis, and lumbar spine to qualitatively evaluate their individual deformities by measuring a number of anatomical landmarks. Three dimensional reconstructions of the data were visualized, analyzed, and then manipulated interactively to perform simulated osteotomies of the proximal femur and pelvis to achieve surgical correction of the hip dysplasia. Severe deformity can occur in spastic cerebral palsy, with serious consequences for the quality of life of the affected individuals and their families. Controversy exists regarding the type, timing and efficacy of surgical intervention for correction of hip dysplasia in this population. Other authors have suggested 3DCT studies are required to accurately analyze acetabular deficiency, and that this data allows for more accurate planning of reconstructive surgery. It is suggested here that interactive manipulation of the data to simulate the proposed surgery is a clinically useful extension of the analysis process and should also be considered as an essential part of the pre-operative planning to assure that the appropriate procedure is chosen. The surgical simulation may reduce operative time and improve surgical correction of the deformity.

    Full Text Available Introduction: Developmental dysplasia of the hip (DDH is the most common hip pathology which can be prevented with early diagnosis and treatment. Prevention, early diagnosis and treatment can be achieved if health professionals are endowed with adequate knowledge. Here, we aimed to evaluate the knowledge level of pediatric trainees and specialists in an education and training hospital and to review the up-to-date information about DDH. Materials and Methods: A multiple choice questionnaire about etiopathogenesis, risk factors, diagnosis and treatment of DDH was answered by the pediatric trainees and specialists in Zeynep Kamil Maternity and Children Education and Training Hospital, İstanbul. NCSS 2007®, USA Software Program is used for statistical analysis.Results: Thirty-nine pediatric residents and twenty-one pediatric specialists were enrolled to the study. Person with DDH in the family, swaddling, breech presentation, female gender, oligohydroamnios were risk factors known with rate ≥70%. Metatarsus adductus, Larsen syndrome, congenital knee dislocation were the least known risk factors (≤10%. The recognition rates of residents and specialist about torticollis, multiple gestation, first born baby and metatarsus adductus as risk factors were statistically different (p<0.05. For the diagnosis of DDH, specialist tended to use conventional methods like physical examination and direct radiographs while residents chose computerized tomography and magnetic resonance imagining. Pediatric residents thought cigarette smoking (48.7% and factors other than mechanic pressure of femoral head for the acetabular development (30.7% as most responsible factors (p<0.05. There was no relationship between duration of residency, duration of being specialists, bearing children and knowledge about DDH. Conclusions: The actual knowledge of pediatricians about DDH should be improved and updated for the success of prevention, diagnosis and treatment of DDH

    Knowledge of the acetabular rim and surface can be invaluable for hip surgery planning and dysplasia evaluation. The acetabular rim can also be used as a landmark for registration purposes. At the present time acetabular features are mostly extracted manually at great cost of time and human labor. Using a recent level set algorithm that can evolve on the surface of a 3D object represented by a triangular mesh we automatically extracted rims and surfaces of acetabulae. The level set is guided by curvature features on the mesh. It can segment portions of a surface that are bounded by a line of extremal curvature (ridgeline or crestline). The rim of the acetabulum is such an extremal curvature line. Our material consists of eight hemi-pelvis surfaces. The algorithm is initiated by putting a small circle (level set seed) at the center of the acetabular surface. Because this surface distinctively has the form of a cup we were able to use the Shape Index feature to automatically extract an approximate center. The circle then expands and deforms so as to take the shape of the acetabular rim. The results were visually inspected. Only minor errors were detected. The algorithm also proved to be robust. Seed placement was satisfactory for the eight hemi-pelvis surfaces without changing any parameters. For the level set evolution we were able to use a single set of parameters for seven out of eight surfaces.

    The developmental dysplasia of the hip (DDH) is a congenital malformation affecting the proximal femurs and acetabulum that are subluxatable, dislocatable, and dislocated. Early diagnosis and treatment is important because failure to diagnose and improper treatment can result in significant morbidity. In this paper, we designed and implemented a computer aided system for the diagnosis and treatment planning of this disease. With the design, the patient received CT (computed tomography) or MRI (magnetic resonance imaging) scan first. A mixture-based PV partial-volume algorithm was applied to perform bone segmentation on CT image, followed by three-dimensional (3D) reconstruction and display of the segmented image, demonstrating the special relationship between the acetabulum and femurs for visual judgment. Several standard procedures, such as Salter procedure, Pemberton procedure and Femoral Shortening osteotomy, were simulated on the screen to rehearse a virtual treatment plan. Quantitative measurement of Acetabular Index (AI) and Femoral Neck Anteversion (FNA) were performed on the 3D image for evaluation of DDH and treatment plans. PC graphics-card GPU architecture was exploited to accelerate the 3D rendering and geometric manipulation. The prototype system was implemented on PC/Windows environment and is currently under clinical trial on patient datasets.

    Developmental dysplasia of the hip (DDH) is one of the most common skeletal anomalies. DDH encompasses a spectrum of the disorder ranging from minor acetabular dysplasia to irreducible dislocation, which may lead to premature arthritis in later life. Involvement of genetic factors underlying DDH became evident when several studies reported chromosomal loci linked to DDH in families with multiple affected individuals. Moreover, using association studies, variants in genes involved in chondrogenesis and joint formation have been shown to be associated with DDH. At least, one study identified a pathogenic variant in the chemokine receptor gene in DDH. No genetic analysis has been reported or carried out in DDH patients from the Middle East. Here, we review the literature related to genetics of DDH and emphasized the usefulness of new generation technologies in identifying genetic variants underlying DDH in consanguineous families.

    Five hundred and twenty German shepherd dogs were screened for elbow dysplasia. The following primary lesions were analysed: joint incongruity (JI), fragmented medial coronoid process (FCP), osteochondrosis or osteochondritis of the medial humeral condyle and ununited anconeal process (UAP). Three radiographic views were used for each joint to achieve a definitive diagnosis. The prevalence of elbow dysplasia was 19.4 per cent. The most frequent lesion was JI (16.3 per cent), followed by FCP (11.3 per cent). UAP was diagnosed rarely (1.1 per cent). Combinations of lesions were very frequent (42.2 per cent of the dysplastic elbows). Although these results may be biased due to prescreening of dogs with UAP, it should be highlighted that JI and FCP occur frequently in German shepherd dogs and are probably the most common primary lesions of elbow dysplasia, although they have been under-reported until now.

    We used a three-dimensional rigid body spring model (RBSM) to compare the contact force distributions on the acetabular surface of the infant hip joint that are produced by three orthopedic treatments for developmental dysplasia of the hip (DDH). We analyzed treatments using a Pavlik harness, a generic rigid splint, and a spica cast. The joint geometry was modeled from tomography images of a 1-year-old female. The articular cartilage was modeled as linear springs connecting the surfaces of the acetabulum and the femoral head, whereas the femur and the hip bone were considered as rigid bodies. The hip muscles were modeled as tensile-only preloaded springs. The treatments with the Pavlik harness and the generic rigid splint were modeled for an infant in supine position with a hip flexion angle of 90 deg. Also, since rigid splints are often recommended when children are initiating their gait phase, we modeled the treatment with the infant in standing position. For the spica cast, we only considered the infant in standing position with a flexion angle of 0 deg, and the fixation bar at two heights: at the ankle and at the knee. In order to analyze the effect of the hip abduction angle over the contact force distribution, different abduction angles were used for all the treatments modeled. We have found that the treatments with the infant in supine position, with a flexion angle of 90 deg and abduction angles between 60 deg and 80 deg, produce a more homogenous contact force distribution compared to those obtained for the treatments with the infant in standing position.

    Full Text Available The purpose of this study was to investigate the need for and choice of stratification factors, and the effects of blinding and placebo in a clinical experiment. Eighty dogs with canine hip dysplasia (CHD were included in a randomized, placebo-controlled and double blind clinical trial with stratified parallel group design, in which body weight and degree of CHD were used as stratification factors. Thirty-eight dogs were allocated to gold bead implantation and 42 to placebo. After six months, 33 of the 42 placebo-treated dogs received gold bead implantation in an open study lasting a further 18 months. The main outcome variable in the study was change in pain signs of CHD as assessed by the owner. No significant difference in the main outcome variable, regardless of the treatment given, could be detected in the two chosen stratification factors. The only factor to influence the main outcome variable significantly was age. The blinding procedure used in the study, in which 60% of the owners correctly guessed the treatment given, was found sufficient. Of those who guessed the treatment erroneously, 88% believed the treatment given was gold bead implantation. The treatment efficacy after six months in the blinded treatment group was found to be significantly larger compared to the efficacy obtained in the open study. A significant placebo effect was therefore detected. Conclusion and Clinical Relevance: The age of the dogs influenced the outcome of the CHD treatment, and is recommended as a stratification factor. A significant placebo effect has to be expected and an optimal blinding procedure is necessary in similar clinical studies.

    Full Text Available Background: Ultrasonography is accepted as a useful imaging modality in the early detection of developmental dysplasia of the hip (DDH. Early detection and early treatment of DDH prevents hip dislocation and related physical, social, economic, and psychological problems. The purpose of this study was to evaluate the reliability of ultrasonographic and roentgenographic measurements measured by seven different observers. Materials and Methods: The alpha angles of 66 hips in 33 patients were measured using the Graf method by seven different observers. Acetabular index degrees on plane roentgenograms were measured in order to assess the correlation between the ultrasonographic alpha angle and the radiographic acetabular index, which both show the bony acetabular depth, retrospectively. Results: The interclass correlation coefficient, measuring the interobserver reliability, was high and statistically significant for the ultrasonographic measurements. There was a negative correlation between the alpha angle and the acetabular index. Conclusions: Ultrasonography, when applied properly, is a reliable technique between different observers, in the diagnosis and follow up of DDH. When assessed concomitantly with the roentgenographic measurements, the results are reliable and statistically meaningful.

  1. The reliability of ultrasonography in developmental dysplasia of the hip: How reliable is it in different hands?

    Full Text Available Background: Developmental dysplasia of the hip (DDH is the most common skeletal dysplasia. Two principal methods used in early diagnosis of DDH are clinical examination and ultrasonographic investigation. Dogruel et al. found a low specificity of clinical examination in patients with DDH. Additionally, Kamath et al. stated that ultrasonography performed by a radiologist in routine clinical practice is more reliable than physical examination performed by the average clinician. In clinical practice, the application and assessment of hip ultrasonography are completed by a single person. This assessment determines the followup of the patient. Thus, hip ultrasonography performed on the same person by different individuals under the same conditions will yield a more accurate assessment of the reliability of ultrasonographic assessment of DDH. Although inter-observer reliability was high in many previous studies of ultrasound image evaluation, reliability rates vary among studies of the application of ultrasonography. Materials and Methods: Inter-examiner reliability of hip ultrasonography was analyzed among four investigators who separately evaluated 100 hips (50 infants. The obtained bone structure angles α, cartilage structure angles β, and distribution of hip types were compared among the investigators. All infants were brought to the hospital for a healthy child followup examination, according to the country's health policy. Babies between 0 and 6 months were included in the study. Babies with any neuromuscular disorders, neural tube defects or any type of genetic anomalies were excluded from the study. The study was explained to the families of all infants and written informed consent was obtained. Results: There was a significant difference in the hip type determined by the investigators with respect to α and β angles (P < 0.01,P< 0.01, P = 0.002.

    Cloning and sequencing of the progesterone receptor gene in dogs have revealed 2 isoforms, A and B, transcribed from a single gene. Distribution of isoforms A and B in canine mammary lesions has hitherto been investigated only by Western blot analysis. This study analyzed progesterone receptor and its isoforms in formalin-fixed, paraffin-embedded tissue samples from canine mammary lesions (4 dysplasias, 10 benign tumors, and 46 carcinomas) using 1-step SYBR Green quantitative real-time polymerase chain reaction (RT-qPCR). Progesterone receptor was expressed in 75% of dysplasias, all benign tumors, and 59% of carcinomas. Carcinomas, and particularly simple epithelial-type carcinomas, displayed the lowest levels of expression. A high rate of agreement was recorded between RT-qPCR and immunohistochemical labeling. Isoforms A and B were successfully amplified, with correlation coefficients of 0.99 and amplification efficiencies close to 2, and were expressed in all lesion types analyzed. Predominance of A over B expression was observed in carcinomas and complex adenomas. Low-grade tumors exhibited higher progesterone receptor messenger RNA (mRNA) levels, but no difference was observed in the expression of isoform A versus B. Analysis of progesterone receptor mRNA isoforms by RT-qPCR was successful in routinely formalin-fixed, paraffin-embedded tissue samples and enabled the distribution of isoforms A and B to be identified for the first time in dysplasias, benign tumors, and malignant tumors of the canine mammary gland. These findings will facilitate future research into the role of progesterone receptor isoforms in the progression of canine mammary tumors. PMID:24249219

    Intra-articular membranous interposition was detected by MRI in the hip joint with residual subluxation of a girl aged 5 years 10 months. This structure, which had low signal intensity on both T1- and T2-weighted images, separated the femoral head from the acetabulum. Histological examination revealed chondrometaplasia, which suggested that this interposition might be transformed to a surface cartilaginous tissue of the secondary acetabulum often observed in residual subluxation of the hip.

    This study was undertaken to document the fate of the hip with reference to its structure and function in patients with spondylo-epi-metaphyseal dysplasia tarda Handigodu type (SEMD{sub HG}). Radiographs of 271 adult patients with SEMD{sub HG} were studied to identify the pattern of long-term sequelae in the hips. Several measurements of the proximal femur and acetabulum were made to quantify morphological alterations in the hip. Fifty-four adult patients were examined and administered a questionnaire to evaluate the extent of disability attributable to the hips. Three patterns of changes in the hips were noted: 35% had acetabular protrusio, 33% had subluxation of the hip, and 32% had no protrusio or subluxation. Distinctly different anthropometric measurements and dimensional alterations around the hip were noted in these three patterns. Patients with protrusio were relatively tall while those with subluxation were the shortest. All the patients had developed degenerative arthritis of the hips by the fourth decade of life irrespective of the pattern of hip involvement. The reduction in the range of hip motion and fixed deformities were most severe in patients with protrusio. All the patients had significant disability and very low functional hip scores. Degenerative arthritis of the hip develops in the majority of patients with SEMD{sub HG}; the symptoms are severe enough to warrant reconstructive surgery by the fourth decade of life. Protrusio or subluxation develops in a third of the patients each; both these complications will influence the surgical approach if total hip arthroplasty is planned. (orig.)

    Full Text Available Objectives:To evaluate the radiographic results from patients with bilateral developmental dysplasia of the hip (DDH who underwent surgical treatment by means of open reduction and Salter osteotomy, with or without associated femoral shortening as described by Ombrédanne.Methods:This was a retrospective descriptive study in which 21 patients with bilateral DDH (42 hips were analyzed. They were treated at Hospital Infantil Joana de Gusmão (HIJG, with operations between August 1997 and October 2009. To evaluate the radiographic results, the acetabular index and the Wiberg center-edge angle were measured, and the Severin and Kalamchi–MacEwen classifications were used. Descriptive and parametric statistical analyses were used to evaluate the data.Results:We did not observe any statistically significant difference in analyzing the radio-graphic parameters, making comparisons regarding the side affected, the order of the procedures and whether femoral shortening was performed, although there was a significant difference between them from before to after the operation.Conclusion:Open reduction in association with iliac osteotomy as described by Salter presented significant improvements in the radiographic parameters analyzed, comparing the pre- and postoperative values. This improvement occurred independently of whether Ombrédanne femoral shortening was performed. The most prevalent complication in the study group was avascular necrosis of the femoral head.

    Full Text Available Abstract Background Developmental dysplasia of the hip (DDH is a congenital or acquired deformation or misalignment of the hip joint which affects mainly females. We hypothesized that HOXD9 gene could be regulated in acetabular size or shape and related in DDH developing. Methods Two hundred and nine Chinese Han female DDH patients and 173 ethnic, age matched healthy female controls were genotyped for HOXD9 two tag SNPs using sequenom method. Results One of the two tag SNPs, rs711822, was not shown significantly differences in genotypic or allelic distribution between case and control group. Comparing the genotypic distribution of rs711819, there was significant differences between DDH patients group and control group (χ2 = 7.54, df =2, P =0.023, and the association to DDH developing reached significance (P =0.045, OR =1.79, 95 % CI: 1.01-3.17 by dominant mode. Conclusion In conclusion, the association between one tag SNP of HOXD9 gene and the development of DDH reach significant in our study population, this result indicate the positive correlation between HOXD9 gene and DDH developing. Further study in larger sample size and different population as well as functional studies will help to understand the pathogenesis of DDH.

    Morphological correlation between the acetabulum and femur at the hip joint is still controversial. We tested the hypothesis that femoral anteversion correlates with acetabular version and coverage in patients with developmental dysplasia of the hip (DDH). Using pelvic computed tomography (CT) images of 79 hips in 49 Asian women with DDH and 49 normal hips, we measured femoral anteversion, the axial and vertical acetabular version and the acetabular sector angle (ASA) to demarcate femoral head coverage. Depending on the location of the acetabular bone defect, dysplastic hips were divided into three subgroups: the anterior, global and posterior deficiency groups. We performed a comparative analysis between dysplastic and normal hips using the Wilcoxon rank sum test, and a relative analysis between femoral anteversion and acetabular measurements in dysplastic hips using Pearson's correlation coefficient. The amount of femoral anteversion in dysplastic hips was greater and more variable than in normal hips (p < 0.0001, p = 0.0277 respectively). Femoral anteversion in dysplastic hips correlated significantly with acetabular anteversion in the groups with anterior and global deficiency subgroups (p < 0.05, r = 0.2990, p < 0.05, r = 0.451 respectively), but not with the posterior deficiency subgroup. Femoral anteversion also correlated with vertical acetabular version. When acetabular coverage was examined, significant correlations were noted between femoral anteversion and anterior and superior coverage, but not with posterior coverage. These correlations were not observed in normal hips. Our results showed significantly greater and more variable femoral anteversion in DDH, and a significant correlation between femoral anteversion and acetabular version and coverage in DDH with anterior and global acetabular bone deficiency.

    The purpose of the present study was to evaluate the 6- to 11-year follow-up results of hemispherical porous-coated cups implanted into dysplastic hips using press-fit technique without screws focusing on the amount of host bone coverage. There were 87 patients who underwent 98 primary total hip arthroplasties. Bony coverage was measured as the angle between the vertical line and the line drawn from the cup center to the lateral edge of the acetabulum, which was named the cup center-edge angle (cup-CE angle). All 98 cups were judged to be bone ingrown. The minimum cup-CE angle was 8.4° (mean, 26.3°). Bone-cup contact of more than 8.4° of the cup-CE angle was large enough for press-fit cups to resist superior directed loads during this follow-up period. PMID:20647158

  15. Transposition of the acetabulum after iliac ischial osteotomy in the treatment of hip dysplasia in infants

    Full Text Available Background. Transposition of the acetabulum after pelvic osteotomy is the most effective surgical method to treat dysplastic hip joint disorders in patients of different ages. According to Salter, iliac osteotomy of the pelvis is the main surgical method used to correct dysplastic acetabulum in 7- and 8-year-old children. In older patients, the pubic symphysis and pelvic ligaments become more rigid, which significantly limits the degree of rotation of the acetabulum. In these cases, a triple pelvic osteotomy is performed to enhance the mobility of the acetabular fragment. This pubic bone osteotomy is performed near the femoral neurovascular bundle, which may be damaged during the procedure.Aim. To describe a technique for transposition of the acetabulum after iliac and ischial osteotomy of the pelvis, which was developed to reduce trauma, prevent vascular complications, and increase postoperative stability of the pelvic ring.Materials and methods. A method developed by the authors for transposition of the acetabulum after iliac and sciatic pelvic osteotomy is described in detail. The surgical method was performed 99 times on 89 children with dysplastic hip joint disorders, and the results are presented.Conclusion. Transposition of the acetabulum after iliac and ischial pelvic osteotomy is an effective treatment for dysplastic instability of the acetabulum in children aged 9–16 years. The procedure is indicated when it is necessary to rotate the acetabular fragment by more than 25°, and there is no need for hip medialization.

    Breeding to reduce the prevalence of categorically scored hip dysplasia (HD), based on phenotypic assessment of radiographic hip status, has had limited success. The aim of this study was to evaluate two selection strategies for improved hip status: truncation selection based on phenotypic record...... versus best linear unbiased prediction (BLUP), using stochastic simulation and selection scenarios resembling those in real dog populations. In addition, optimum contribution selection (OCS) was evaluated. Two traits were considered: HD (as a categorical trait with five classes and a heritability of 0.......45 on the liability scale) and a continuous trait (with a heritability of 0.25) intended to represent other characteristics in the breeding goal. A population structure mimicking that in real dog populations was modelled. The categorical nature of HD caused a considerably lower genetic gain compared to simulating HD...

    The primary purpose of this article is to draw closer attention to a particularly important orthopedic problem: the prevention and early treatment of Developemental Displasia of the Hip (DDH) in children, using ultrasonography (USG) as the main diagnostic method. The article presents clinical material collected over a period of several years in the Children's Orthopedic Outpatient Clinic at the County Pediatric Hospital in Toruń. The material covers a period of six years (1994-1999), but the experience of this clinic in the area of DDH dates back many years. The entire system of complex diagnosis, prevention, and treatment of dysplasis hip joints in children will be presented in the light of Polish realities. The authors' intention is to portray the rich potential of USG technology in the diagnosis of DDH, to demonstrate its effectiveness, and to promote the use of this method among orthopedic surgeons and pediatricians, who may have differing opinions concerning its actual value. The problem of the early prevention of DDH is an interdisciplinary one, involving first neonatologists and obstetricians, later pediatricians, orthopedic surgeons, and even primary care physicians whose practice includes infants. This issue has been the subject of many national and international conferences, congresses and symposia. PMID:17984920

    Highlights: • The article adds information about the pubo-femoral distance (PFD) used as a simple tool to detect dysplastic hips in neonates. This articles shows that the PFD is comparable with the “gold standard” Graf method for the diagnosis of developmental dysplasia of the hip and it can be used as a screening tool for its diagnosis, regardless the radiologists’ experience, with high accuracy. - Abstract: Purposes: To evaluate whether the pubo-femoral distance (PFD) can be used as an accurate screening test to diagnose developmental dysplasia of the hip (DDH) in an at-risk population compared with the Graf method. Second, to determine whether PFD assessment is feasible and reproducible regardless of the observer's experience. Materials and methods: IRB approved this retrospective single-institution study. Written informed consent was waived. Between January 2010 and March 2012, 116 neonates at risk for DDH were included. Infants’ hips were distributed into two groups according to recommendation for treatment: non-dysplastic (ND; Graf I/IIA; 211 hips; 69 females/37 males) and dysplastic hip (DH; Graf IIB/IIC/III/D/IV; 21 hips; 8 females/3 males). One resident and one experienced radiologist reviewed ultrasonography images performed in the fourth week. To compare the groups, Student's t and Mann–Whitney tests for normally and non-normally distributed covariates were performed. Accuracy of PFD to diagnose DDH was calculated. Intraclass correlation coefficient (ICC) was calculated to assess inter-observer agreement. Results: Mean PFDs of ND group were 3.09 mm at neutral position and 3.64 mm with the hip flexed. Mean PFDs of DH group were 6.29 mm and 7.59 mm, respectively. Sensitivity, specificity, and accuracy of PFD were 94.4%, 93.4%, and 97.2% (cut-off = 4.6 mm) at neutral position and 94.4%, 89.0%, and 95.5% (cut-off = 4.9 mm) with hip flexed. ICCs were 0.852 and 0.864, respectively. Conclusions: PFD is comparable with Graf method, enabling

    @@ Congenital absence of the cruciate ligaments is an extremely rare condition with a prevalence of 0.017 per 1000 live births.~1 Niebauer and King~2 first reported this disease in 1960, and after that, similar cases have been reported. These cases are usually associated with other deformities of the knee joint, such as the joint dislocation, absence of the tibial intercondylar eminence, deformity of the meniscus, dysplasia of the distal femur, etc.~3 However, its association with multiple congenital abnormalities in other areas of the body has been rarely reported. Here, we report a patient with congenital deficiency of bilateral anterior cruciate ligaments associated with scoliosis and hip dysplasia, together with the result of four years follow-up along with a literature review.

    Objective: To analyse in detail the two methods for the measurement of the center-edge (CE) angle in developmental dysplasia of the hip (DDH) in children and adolescents. Design: Four observers independently interpreted the radiographs of 51 surgically treated and 15 unaffected hips on two occasions. CE angle was measured by using two methods: classic (Wiberg) and refined (Ogata et al.). Intraobserver and interobserver variations of both methods were calculated and the effect of age and treatment type on the two measurement methods were analysed. Results: Following 528 measurements in 66 hips, the mean classic CE angle was 28.2 and the mean refined CE angle, 19.9 . The classic CE angle had nearly 1 less intraobserver and interobserver variation than the refined CE angle. Classic angle measurements were obviously higher than refined ones in the hips of children under 9 years of age and in hips in which an innominate osteotomy had been performed. Conclusion: Although CE angle of Wiberg, which is an important radiographic indicator, has an adequate level of reliability and reproducibility it may not reflect the true lateral femoral head coverage in some cases.

    Background: The technique of medialization has been used to reconstruct acetabula at the level of true acetabula in total hip arthroplasty (THA) in patients with developmental dysplasia of the hip (DDH). Appreciation of the bone stock in the medial acetabular wall is significant for making an optimal acetabular reconstruction plan and avoiding complications. Purpose: To evaluate the bone stock of the medial acetabular wall and its relation to the degree of subluxation in patients with DDH using computed tomography (CT). Material and Methods: Helical CT scans of 27 hips were obtained from 21 patients with osteoarthritis secondary to DDH who were scheduled for total hip arthroplasty. Eleven hips belonged to Crowe class I, while 16 hips belonged to Crowe class II/III. The raw CT data were reprocessed in various planes by scrolling multiplanar reformation (MPR). Acetabular opening, depth, and medial bone stock, as indicated by the minimum thickness of the medial acetabular wall, were measured in the transverse reformed MPR plane. Results: The minimum thicknesses of the medial acetabular wall in Crowe-I and Crowe-II/III hips were 3.8+-2.1 mm and 7.1+-3.1 mm, respectively, with statistically significant differences between the groups (P<0.05). Furthermore, the bone stock in the medial acetabular wall correlated with the degree of subluxation (R=0.69) and the acetabular depth (R= ;- ;0.71). Conclusion: There was significantly more bone stock in the medial acetabular wall in patients with higher-degree subluxation than there was in the less-severe class. This difference should be taken into consideration when reconstructing acetabula in THA in patients with DDH using the technique of medialization

    BACKGROUND:Total hip arthroplasty is an optimal choice for patients with late hip dysplasia. Crowe type IV developmental dysplasia of the hip increases the difficulty of the operation, and the surgery is controversial. OBJECTIVE:To evaluate the clinical effects of total hip arthroplasty on Crowe type IV developmental dysplasia of the hip and the method of reconstruction of acetabulum and the treatment of proximal femur. METHODS:A total of 12 patients (14 hips) with Crowe type IV developmental dysplasia of the hip underwent total hip arthroplasty. Preoperative Harris hip score was averagely (35.0±6.8) points. Al hips were treated with smal acetabular components combined with medial protrusion technique in acetabular reconstruction, as wel as subtrochanteric shortening osteotomy in femur. Joint function of hips was evaluated according to the Harris hip score. RESULTS AND CONCLUSION:Al patients were fol owed up with an average of 4.6 years (ranged 1 to 7 years). Two cases (two hips) suffered from infraction of greater trochanter of femur during replacement, and it was fixed with wire. There was complete sciatic nerve injury in one case, which partial y restored after conservative treatment for 1 month. No infection, prosthesis loosening, or deep venous thrombosis with obvious clinical manifestations was visible. Bone union was observed at the site undergoing osteotomy at the side of femur. After replacement, final fol ow-up showed that Harris hip score was averagely (84.0±7.0) points. The mean amount of postoperative leg lengthening was 5 cm (range 4-6 cm). Shortened limbs were corrected satisfactorily. These results suggested that total hip arthroplasty using smal acetabular component, medial protrusion, and femoral subtrochanteric shortening osteotomy technique for the Crowe type IV developmental dysplasia of the hip can effectively restore hip function and leg length. The long-term curative effects require further investigations.%背景:人工全髋关节置

    The objective of this study was to investigate the type of chemical restraint used by French practitioners to perform official hip screening radiographs, to determine the proportion of dogs under general anesthesia versus dogs under sedation, and to search for a difference in hip dysplasia (HD) prevalence between the two groups. From September 2005 to August 2008, 3302 conventional ventrodorsal hip extended radiographs sent for official scoring to the same panellist were selected because information related to the type of chemical restraint had been provided. There were 2825 dogs under general anesthesia and 477 were sedated. Chemical restraint used by French veterinarians to perform HD screening radiographs is mainly based on general intra-venous anesthesia with an alpha2 agonist associated with ketamine. A single injection of alpha2 agonist is also mostly used for dogs which are radiographed while under sedation. A very low (1.7%) difference in HD prevalence was noted between the anesthetized and the sedated group. Except for acepromazine, which has been demonstrated to provide insufficient muscle relaxation to show evidence of hip laxity, the protocols seem acceptable as regards the Federation Cynologique Internationale requirements for HD screening.

    We investigated the three-dimensional morphological characteristics of the pelvis in adult female patients with developmental dysplasia of the hip (DDH), using computerized tomography (CT) images. Forty-two subjects with normal hips and 40 DDH patients were recruited for the study. In the DDH group, the average transverse diameter of the pelvic inlet was significantly less and the average transverse diameter of the pelvic outlet was significantly greater than the measurements in the normal group. Further, the bony birth canal in DDH patients exhibited a higher incidence of anthropoid-type geometry, as defined by a longer sagittal diameter relative to the transverse diameter of the pelvic inlet. These findings indicate a characteristic pelvic geometry and suggest different development of the pelvis in the transverse direction in DDH patients. In addition, the obstetric conjugate length/transverse diameter of the pelvic inlet ratio was correlated to the degree of severity of acetabular dysplasia. This finding suggests that DDH is a manifestation of a developmental characteristic of the pelvis. (author)

    Background and purpose Avascular necrosis (AVN) is a major cause of disability after treatment of developmental dysplasia of the hip (DDH), leading to femoral head deformity, acetabular dysplasia, and osteoarthritis in adult life. Type-II AVN is characterized by retarded growth in the lateral aspect of the physis or by premature lateral fusion, which produces a valgus deformity of the head on the neck of the femur. We investigated the effect of medial percutaneous hemi-epiphysiodesis as a novel technique in the treatment of late-diagnosed type-II AVN. Patients and methods 9 patients (11 hips) with a diagnosis of type-II AVN who underwent medial percutaneous hemi-epiphysiodesis after the surgical treatment for DDH were included in the study. 10 patients (12 hips) with the same diagnosis but who did not undergo hemi-epiphysodesis were chosen as a control group. Preoperative and postoperative articulotrochanteric distances, head-shaft angles, CE (center-edge) angles, and physeal inclination angles were measured. The treatment group underwent medial hemi-epiphysodesis at a mean age of 8 years. The mean ages of the treatment group and the control group at final follow-up were 14 and 12 years respectively. The mean duration of follow-up was 5.7 years in the treatment group and 8.3 years in the control group. Results Preoperative articulotrochanteric distance, head-shaft angle, and functional outcome at the final follow-up assessment were similar in the 2 groups. However, preoperative and postoperative CE angles and physeal inclination angles differed significantly in the treatment group (p < 0.05). The final epiphyseal valgus angles were better in the treatment group than in the control group (p = 0.05). The treatment group improved after the operation. Interpretation Medial percutaneous epiphysiodesis performed through a mini-incision under fluoroscopic control is a worthwhile modality in terms of changing the valgus tilt of the femoral head.

    J.D. Mande

    2003-06-01

    Full Text Available Ventrodorsal pelvic radiographs were made of 32 adult dogs under general anaesthesia. The hip joints were evaluated according to the severity of osteoarthritic changes graded as 0, 1, 2 or 3. The dogs were euthanased, the hip joints opened and the ligamentum capitis femoris dissected out in toto. The volume of each ligament was determined using a water displacement technique and the mean volume compared to the four radiographic grades of osteoarthritis. There was an inverse correlation (r = -0.75 between the mean volume of the ligamentum capitis femoris and the increasing severity of osteoarthritis as assessed by radiography. The results confirmed the crucial role of radiography in the clinical evaluation of hip dysplasia and osteoarthritis in the adult dog. Assessment of the volume of the ligamentum capitis femoris revealed that it is an important tool for research in canine hip dysplasia and osteoarthritis.

    2010-01-01

    In recent years, canine genetics had made huge progress. In 1999 the first complete karyotype and ideogram of the dog was published. Several linkage and RH maps followed. Using these maps, sets of microsatellite markers for whole genome scans were compiled. In 2003 the sequencing of the DNA of a female Boxer began. Now the second version of the dog genome assembly has been put online, and recently, a microchip SNP array became available. Parallel to these developments, some causal mutations for different traits have been identified. Most of the identified mutations were responsible for monogenic canine hereditary diseases. With the tools available now, it is possible to use the advantages of the population structure of the various dog breeds to unravel complex genetic traits. Furthermore, the dog is a suitable model for the research of a large number of human hereditary diseases and particularly for cancer genetics, heart and neurodegenerative diseases. There are some examples where it was possible to benefit from the knowledge of canine genetics for human research. The search for quantitative trait loci (QTL), the testing of candidate genes and genome-wide association studies can now be performed in dogs. QTL for skeletal size variations and for canine hip dysplasia have been already identified and for these complex traits the responsible genes and their possible interactions can now be identified.

    In order to look for phenotypic correlation between hip (HD) and elbow (ED) dysplasia, we used radiographic scoring obtained from 1,411 dogs of different breeds, which were evaluated for authoritative grading of both conditions. In this population, we found that the risk ratio for an animal to be simultaneously affected by HD and ED is 1.67. For a dog with ED, the risk ratio to be affected by HD increases as the ED grade increases. Similarly, for a dog affected by HD, the risk ratio to be affected by ED increases as the HD grade increases. In a dog affected by HD or ED, the clinician should look for the second condition in the same animal. Due to the low, yet positive correlation, selection against one trait will not affect the other trait sufficiently. Therefore selection has to be conducted at reduction of HD as well as reduction of ED. PMID:19997665

    Normative references for radiographic measurements commonly used in the diagnosis of developmental dysplasia of the hip at skeletal maturity are incomplete. The present study therefore aimed to establish new gender-specific standards for measurements reflecting the acetabular morphology, namely Sharp's angle, the acetabular roof angle of Toennis (AA) and the acetabular depth-width ratio (ADR), and measurements reflecting the position of the femoral head related to the acetabulum, namely the center-edge (CE) angle of Wiberg, the refined CE angle of Ogata, and the femoral head extrusion index (FHEI). The joint space width (JSW) is also reported. The population-based 1989 Bergen Birth Cohort (n = 3,935) was invited at age 19 years to a follow-up during 2007-09, of which 2,038 (52 %) attended. A standardized antero-posterior radiograph was assessed. The normative references are presented as mean {+-} standard deviation (SD) and 2.5-97.5 percentiles with 95 % confidence intervals. A total of 2,011 (841 males, 1,170 females, mean age 18.6 (SD 0.6)) radiographs were analyzed. Sharp's angle was 38.8 {+-} 3.5 in males and 40.7 {+-} 3.5 in females, with 97.5 percentiles of 46 and 47 , respectively. The CE angle was 32.1 {+-} 6.1 in males and 31.0 {+-} 6.1 in females, with 2.5 percentiles of 21 and 20 , respectively. The FHEI was 86.0 % {+-} 6.3 % in males and 85.6 % {+-} 6.6 % in females, with 2.5 percentiles of 74 and 73 , respectively. Updated gender-specific reference ranges for radiographic measurements commonly used for hip dysplasia at skeletal maturity are reported, similar to or slightly wider than those described in the literature. Statistically significant gender differences have been confirmed for most of the measurements. (orig.)

    Full Text Available Introduction: Epiphyseal dysplasia of the femoral head (EDFH is defined as an alteration in the development of the child’s hip, characterized by delayed ossification of the proximal femoral epiphysis. Methods: Herein, we present six cases of epiphyseal dysplasia of the femoral head (EDFH, seen by the principal author (EVA within the last six years with minimum follow up at 15 months. Results: The cases were all diagnosed as casual findings. None of the children had symptoms or clinical signs in the hip, only one had a history of hip pain for five days, two months prior, which was diagnosed at the time as transient synovitis. Discussion: Among the differential diagnoses, the main one is Perthes disease, which is differentiated by several parameters like earlier age onset for EDFH (in children below 4 years of age, bilateralism (50% vs. 10%, and a calmer presentation in Meyer’s dysplasia. The evolution in Meyer’s dysplasia is toward improving radiographic changes. None of the patients revealed incongruence of the hip or early degenerative changes, indicating an excellent prognosis. Many authors think it is a variant of the normal ossification of the femoral head.

    Objectives to evaluate the radiographic results from patients with bilateral developmental dysplasia of the hip (DDH) who underwent surgical treatment by means of open reduction and Salter osteotomy, with or without associated femoral shortening as described by Ombrédanne. Methods this was a retrospective descriptive study in which 21 patients with bilateral DDH (42 hips) were analyzed. They were treated at Hospital Infantil Joana de Gusmão (HIJG), with operations between August 1997 and October 2009. To evaluate the radiographic results, the acetabular index and the Wiberg center-edge angle were measured, and the Severin and Kalamchi–MacEwen classifications were used. Descriptive and parametric statistical analyses were used to evaluate the data. Results we did not observe any statistically significant difference in analyzing the radiographic parameters, making comparisons regarding the side affected, the order of the procedures and whether femoral shortening was performed, although there was a significant difference between them from before to after the operation. Conclusion open reduction in association with iliac osteotomy as described by Salter presented significant improvements in the radiographic parameters analyzed, comparing the pre- and postoperative values. This improvement occurred independently of whether Ombrédanne femoral shortening was performed. The most prevalent complication in the study group was avascular necrosis of the femoral head.

    Full Text Available PURPOSE: The purpose of this hospital-based case-control study was to evaluate the patient-related risk factors for aseptic loosening after total hip arthroplasty (THA and total knee arthroplasty (TKA in Chinese patients. METHODS: From January 2000 to December 2012, 67 patients undergoing THA and TKA who developed aseptic loosening were detected as case subjects and 336 patients without aseptic loosening, matched by the year of index surgery and type of surgery, were selected as controls. Conditional logistic regression was used to compute odds ratios (ORs and 95% confidence intervals (CIs. RESULTS: The demographic factors and comorbid conditions associated with a risk-adjusted increase in aseptic loosening (in decreasing order of significance were a rural place of residence (OR = 2.28; 95% CI: 1.21-4.30; p = 0.011, body mass index (BMI ≥ 28 kg/m(2 (vs. 18.5-28 kg/m(2 (OR = 2.29; 95% CI: 1.19-4.41; p = 0.013, developmental dysplasia of the hip (DDH (OR = 2.91; 95% CI: 1.11-7.66; p = 0.030, tobacco abuse (OR = 2.88; 95% CI: 1.05-7.89; p = 0.039, and age <45 years (vs. 45-65 years (OR = 2.63; 95% CI: 1.01-6.80; p = 0.047. CONCLUSIONS: Patients aged <45 years and those with a BMI of ≥ 28 kg/m(2, a preoperative diagnosis of DDH, history of tobacco abuse, or living in rural areas are at increased risk for aseptic loosening after THA and TKA in Chinese population.

    Full Text Available Introduction. Use of Pavlik harness for the treatment of DDH can be complicated for parents. Any misuse or failure in the adjustments may lead to significant complications. An abduction brace was introduced in our institution, as it was thought to be easier to use. Aim. We assess the results for the treatment of DDH using our abduction brace in children of 0–6 months old and compare these results with data on treatments using the Pavlik harness. Method. Retrospective analysis of patients with DDH from 0 to 6 months old at diagnosis, performed from 2004 to 2009. Outcomes were rates of reduction of the hip and avascular necrosis of the femoral head (AVN. Follow-up was at one year and up to 4 years old. Results. Hip reduction was successful in 28 of 33 patients (85%, with no AVN. Conclusion. Our results in terms of hip reduction rate and AVN rate are similar to those found in literature assessing Pavlik harness use, with a simpler and comfortable treatment procedure.

    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.

    Developmental dysplasia of the hip( DDH )is a common skeletal disease during the period of infant and child, and its morbidity is nearly 1‰-2‰. Hip dysplasia refers to an anomaly in the size, shape, o-rientation, or organization of the femoral head, acetabulum, or both. This disease usually comprises shallow ac-etabulum and/or lax joint capsule. Hip instability, joint pain, gait abnormalities and premature arthritis are common clinical signs. It is important to prevent,diagnose and treat DDH as early as possible. More about the etiopathogenesis should be learned for the prevention, and genetic factor is one of the most important etiologi-cal factors of the disease.%髋关节发育不良(DDH)是婴幼儿时期一种常见的骨科疾病,发病率为1‰ ~2‰.其是由股骨头和(或)髋臼的大小、形态、取向和(或)组织构成异常导致,通常指关节囊松弛和(或)髋臼太浅.DDH可导致膝关节不稳定、关节疼痛、步态异常及早发型骨性关节炎,因此早期预防、早期诊断和早期治疗显得尤为重要.预防该病必须了解病因,而遗传因素是DDH的重要病因之一.

    Objective To study the indications and mid-term outcomes of periacetabular osteotomy on adult patients of developmental dysplasia of the hip (DDH). Methods Twenty-five adult patients with DDH underwent periacetabular osteotomies through modified Smith-Peterson approach. There were 19 females and 6 males with an average age of 25.5 years (range, 18-45). Every patient had a single dysplasia hip, including 14 hips in the left, and the other 11 in the right. Three cases were operated formerly, 2 of them received Chari osteotomy and 1 received Salter osteotomy. Before operation 13 hips were T(o)nnis Grade 0 osteoarthritis, 9 hips were Grade Ⅰ , 3 hips were Grade Ⅱ. The Shenton line of 18 hips was broken. The lateral center-edge angle was 4.57°±7.39°, the anterior center-edge angle was 0.95°±6.02°, the horizontal tilt angle was 32.50°±5.96°, the femoral head extrusion index was 38.11%±5.70%, the Harris hip score was 75.32±7.51 points. Changes of the indexes mentioned above were observed during the period of follow-up.Results All patients were followed up for average 4.5 years (range, 2.0-7.5). Compared with the preoperative radiographic severity at the latest follow-up, 3 hips of T(o)nnis Grade Ⅰ improved to Grade 0, 2 hips of Grade Ⅱ improved to Grade Ⅰ, 1 hip of Grade Ⅰ changed into Grade Ⅱ. The incident of the break of Shenton line decreased to 10 hips. The lateral center-edge angle improved to 29.07°±5.81° the anterior centeredge angle improved to 29.52°±4.51°, the horizontal tilt angle decreased to 19.17°±4.95°, the femoral head extrusion index decreased to 24.20%±4.83%, the Harris hip score increased to 84.88±4.88 points.

    There have been a small number of case reports describing late normal-hip dislocations in children who were later diagnosed with developmental dysplasia of the hip. Here, we contest the assumption that normal hips can dislocate. We argue that (as in our case) the ultrasound scans in all published case reports on late dislocated normal hips did not show results that were entirely normal and therefore, so far, there has been no convincing evidence of a dislocation of a normal hip. We also want to highlight the importance of meticulous ultrasound and clinical assessments of high-risk children by an experienced orthopaedic surgeon. PMID:25144883

    Adult congenital hip dysplasia(ACHD) is a congenital defect of acetabular disease. It may develop subluxation or luxation of hip after a long term, and osteonecrosis of the femeral head may occur at last. Now the patients with ACHD at early stage are treated with the operation of rotational osteotomy of the acetabulum, but in later period it can only be treated with the operation of total hip replacement. No matter which method is selected, nursing care of perioperative period plays a very important role in recoveries of the patients.%成人先天性髋关节发育不良是一种髋臼先天性发育缺陷的疾病,长期发展会形成髋关节半脱位、脱位,最终甚至可能出现股骨头坏死等严重合并症.对于早期患者目前主要采用髋臼旋转截骨手术治疗,而晚期出现股骨头脱位及坏死则只能通过全髋关节置换进行治疗.不论哪种手术方式,围手术期的护理时于患者的健康恢复都有着非常重要的意义.

    Objective To investigate the pathological mechanism of hip dysplasia. Methods The left knee joints of eighteen rabbits were fixed in extending position with plaster cylinder for four weeks, but their hip joints were flexed. The right side served as control. Roentgenogram was made in all animals. The changes of the xray films and the pathological findings between left and right hips were compared. Results Appearance of hip dysplasia was obvious at four weeks after plaster fixation. There were pathological changes, including shallow acetabulum and flat femoral head, increased acetabular index and decreased acetabular head index on the x-ray films.Conclusion The hip dysplasia is the result of prolonged extending position of the knee joint. Abnormal knee posture seems to be one of the important factors of hip dysplasia. This kind of deformation may be worsened with time.

    Developmental dysplasia of the hip (DDH) has a broad spectrum of presentation with the minor findings resolving spontaneously and the most severe ones resulting in disability, if not diagnosed early in life. Diagnosis in the first few months of life allows conservative treatment with complete resolution in most cases. Suspicion of DDH is based on ethnic, family, and pregnancy history, and on physical examination of the newborn. Imaging assists in the diagnosis and follows the treatment. Different modalities have their own advantages and disadvantages. This article deals with the description of the disease, risk factors, statistics, the physical examination as applied to real-time sonography, and imaging (plain radiography, arthrography, computed tomography, and magnetic resonance imaging).

    'Hip' pain is usually located in the groin, upper thigh or buttock and is a common complaint. Slipped capital femoral epiphysis, avascular femoral head necrosis and apophyseal avulsion are the most common diagnoses in childhood and adolescents. Strains and fractures are common in sport-active adults. Osteoarthritis occurs in middle-aged and older adults. Trauma may result in femoral head fracture or typical muscle and tendon sprains and bursitis. Septic or inflammatory arthritis can occur at every age. Septic arthritis, fractures and acute epiphyseal slipping are real emergency cases. Congenital dysplasia of the hip joint may lead to labral tears and early osteoarthritis. The most important hip problems in children, adolescents, adult and older people are discussed; these problems originate from intra-articular disorders and the surrounding extra-articular soft tissues. Medical history, clinical examination and additional tests, including imaging, will be demonstrated. Principles of treatment are given for specific disorders. PMID:12659822

    To establish the current status of canine hydrotherapy in the UK and to ascertain information regarding the current use of hydrotherapy, a questionnaire was sent to 152 hydrotherapy centres throughout the UK, from which 89 responded. Hydrotherapy was found to be a rapidly growing business. Stand-alone centres were in existence; however, many centres were connected to other businesses, including boarding kennels and general practice veterinary surgeries. The dogs using the facility were mainly pedigree breeds, particularly labrador retrievers (30 per cent), and the most commonly encountered conditions were rupture of the cranial cruciate ligament (25 per cent), hip dysplasia (24 per cent) and osteoarthritis (18 per cent). The proportion of qualified versus unqualified staff varied between centres, highlighting a need for improved regulation of this aspect of the industry. However, all the dogs treated by the hydrotherapy centres surveyed were direct veterinary referrals, suggesting a good degree of professionalism in the field and a high regard for the benefits of hydrotherapy.

    Purpose: To evaluate a possible dose reduction in pediatric pelvic radiographs in congenital hip dysplasia using a digital flat-panel system instead of a phosphor-storage system. Materials and Methods: During a six-month period, all pediatric patients referred for pelvic radiography for the evaluation of congenital hip dysplasia were randomely assigned to be examined by either a phosphor-storage system or a digital flat-panel system, whereby the latter system was operated with half the radiation dose. Thirty pairs of radiographs were assessed for the visibility of 16 anatomic details and for 5 orthopedic-radiographic measurements (5-point scale with 1 = excellent; three independent observers). The projection indices of Ball and Kommenda and of Toennis and Brunken were calculated for all radiographs. The Student's t-test was used to compare the flat-panel and the phosphor-storage radiographs for observers' assessments, patients' age and projection indices. Results: In a total of 7560 observations, the scores for the visibility of anatomic details and orthopedic-radiographic measurements were respectively 2.72 and 2.64 for the flat-panel system and 2.93 and 2.79 for the phosphor-storage system. No significant differences were found between both systems (p > 0.05) and between patient age and projection indices (p > 0.05). Conclusion: Pediatric pelvic radiographs can be obtained with a digital flat-panel system using half the radiation dose instead of a phosphor-storage system without sacrificing relevant information in the diagnosis of congenital hip dysplasia.

The X-linked recessive form (SEDL affects boys and is characterized by reduced height, arm span exceeding total height, and barrel chest deformity. The radiographic phenotype comprises a hump-shaped deformity of vertebral bodies and mild epiphyseal dysplasia of the femoral head associated with early signs of hip arthrosis.The disorder is caused by mutations in the SEDL (or sedlin gene on Xp22.12-p22.31. SED should be kept in mind as a differential diagnosis in men with early “primary” bilateral osteoarthrosis.Case Report: Here, 11 years old twins diagnosed as SED due to walking disability, limitation of joint motion, pain at the hips and disability in standing for a long time were presented. Discussion: This rare skelatal dysplasia must be kept in mind in patients with painful spine and hip joints, and walking disability. (Jo­ur­nal of Cur­rent Pe­di­at­rics 2011; 9: 97-9

Renal stenosis can be asymptomatic or complicated with arterial hypertension or less frequently with renal insufficiency. Carotid and vertebral involvements are less frequent (10-35%). Surgical management of fibromuscular dysplasia is now less common because of the better efficacy of percutaneous transluminal angioplasty. Thus, histologic characteristics are no longer relevant prognostic criteria. Clinical features and outcome vary according to angiographic presentation (focal or multifocal disease), with an increased recovery rate of hypertension with focal lesions. In the presence of renal fibromuscular dysplasia, only symptomatic patients are revascularized (recent or resistant hypertension) or patients with asymmetric renal size or impaired renal function. Transluminal angioplasty is the first-line treatment except for patients with complex lesions or stenosis associated with aneurysm. PMID:25455952

    Objective Congenital muscular torticollis (CMT) and developmental dysplasia of the hip (DDH) are common congenital problems in infants. Association between CMT and DDH has been reported in literatures. The aim of this study was to assess coexistence of DDH in infants with CMT and curative effects of its rehabilitative therapy. Methods In total, 187 infants less than two months old with CMT were recruited in the study. DDH was diagnosed and graded by Graf's bilateral hip type B ultrasonography and pelvic X-ray films. Massage manipulation, magnetic strapping, postural orthosis at home and heat compress were instituted for CMT and frog spica device and hip-flexion abduction plaster immobilization were instituted for DDH. Their early rehabilitative effects were evaluated. Results DDH was coexisted in 24 of 187 infants with CMT, with incidence of 12. 8%. The hips of 22 infants were graded as type Ⅱ b (91.7%) and two as type Ⅲ a (8.3%), and eight at the left side and seven at the right side.Comorbid hips completely recovered normal with early frog spica device and hip-flexion abduction therapy in 24 infants. Conclusions Coexistence of CMT and DDH are relatively common in infants. Type B ultrasonography can be used as a measure for screening DDH in neonates with CMT. Early rehabilitative therapy is effective for those coexisted with DDH and CMT at the same time.%目的 了解先天性肌性斜颈(CMT)伴发育性髋关节异常(DDH)发生情况及其康复治疗的效果.方法 对187例月龄<2个月的CMT患儿,应用Graf方法行双侧髋关节B超、骨盆X线摄片检查以明确诊断,筛查DDH并对其髋关节类型进行分类.CMT采用手法推拿、磁贴、家庭体位矫治、热敷治疗,DDH采用屈髋外展支架、外展位石膏治疗,观察早期康复治疗的效果.结果 187例CMT患儿中,24例(12.8%)合并DDH;髋关节类型:Ⅱb型22例(91.7%),Ⅲa型2例(8.3%).24例患儿通过早期康复和屈髋外展支具治疗,共存疾

    Objective To study the stress distribution in the acetabular cup-bone interface affected by the structural bone graft for the acetabulum reconstruction during the total hip replacement (THR) in treating the dysplasia of hip by using the three dimensional (3D) finite element analysis. Methods The acetabulumm of the hip with dysplasia was scanned by CT.The computer simulation technology was used to reconstruct the three-dimensional (3D) model of the pelvic from CT scan picture in order to observe the dysplasia of the hip.The structural bone graft for reconstruction of the acetabulum reconstruction in THR was simulated.Then the pelvis and acetabular cup models were meshed.The mechanical analysis tool was used to analyze the 3D model, and the stress data in the acetabular cup-bone interface was achieved.After the statistical analysis of the experimental results, the structural bone graft affecting the stress distribution in the acetabular cup-bone interface was observed.Results The structural bone graft augmented the deficient acetabulum and improved the bone-bed inclusion of the cup during THR in treating the dysplasia of the hip, which leaded to greater contact area and smaller stress per unit area. The structural autograft which covered the anterior-lateral part of the cup bore greater stress.Conclusion The acetabular reconstruction with the structural bone graft improves the bone-bed inclusion of the cup during THR in treating the dysplasia of the hip.The stress deconcentration due to the larger contact area could benefit the stability of the cup.The coverage of the cup by the graft should not be too much, otherwise, the great stress on the structural bone graft would increase the risk of loosening.%目的:利用三维有限元力学分析方法,研究髋关节发育不良患者髋臼外上缘结构性植骨重建髋臼、增加臼杯假体包容对髋臼假体-骨界面间的应力分布情况的影响。方法选取髋关节发育不良患者的骨盆为

    Objective To explore the installing methods of hip prothesis in a total hip arthroplasty for patients of osteoarthritis secondary to end-stage acetabular dysplasia. Methods Between January 2002 and January 2008.a total of 60 hips in 52 patients with advanced osteoarthritis secondary to acetabular dysplasia underwent the total hip arthroplasty and were followed up. Among the patients,6 were male and 46 were female,with their ages ranging from 46 to 72 years and a average age of 62 years. The bilateral arthroplasty was performed in 8 patients and the unilateral arthroplasty in 44 patients. The main symptoms were pain and claudication. According to the developmental degree of acetabulums,three methods were adopted to perform the total hip arthroplasty,which were deepen acetabulum,inward deepening acetabulum and bone transplantation on external upper lip of acetabulum. The Harris scores were applied to evaluate function of the hip during follow-up. X-ray films for both joints were taken in order to learn the coalescence of acetablum with its bone bed after 3,6,9,12 months and every 1 years after operation. The follow-up time ranged from 2 years to 8 years,with an average of 4 years and 6 months. Results At the end of follow-up,the acetabulum prostheses contacted well with their beds of 45 years and the recovery of joint function was satisfactory and no sign of aseptic loosening among the cases of deepen acetabulum and inward deepened acetabulum. However,in 5 of 6 acetabulums which implanted bone on their external upper lip,there was a radiolucency between the implanted bone and the acetabulum prothesis after 2 years of the operation. No sign of aseptic loosening was found. Conclusion While performing total hip arthroplasty,various methods should be adopted according to the bed of acetabulum for the joints of osteoarthrosis due to acetabulum dysplasis. For the patient of enough bone at the bottom of acetabulum bed the acetabulum should be installed by the operation

    To determine the efficiency of an early diagnosis programme using ultrasounds (US) of development dysplasia of the hip (DDH), using different criteria to delect patients according to the sex: universal to girls, but only including boys with a DDH risk factor (a physical pathological examination of new born babies, babies born feet first, family history and orthopaedic deformities). Of the 3,469 children born at our hospital during one specific year, 1,721 were included in the programme. US was carried out on all of them, following the Graf technique, when they were a month old, with the exception of the new born babies who were studied during their first week by means of a physical pathological examination. The babies who were diagnosed with physically immature hips in this first study using US; were followed up. Thirty-two babies born during the year suffered from DDH (a rate of 9.2 per thousand). Among them there was only 1 case of delayed DDH (that was not detected in the programme). Seven babies were diagnosed with DDH thanks to the follow up procedures carried out on babies with physically immature hips. Putting this programme for early diagnosis into practices has achieved the almost total disappearance of delayed DDH. When comparing the results with previous periods, where different early detection systems were used, the duration and the aggressiveness of the treatment has reduced considerably. Follow up procedures using US of physically immature hips is obligatory. (Author) 14 refs.

  6. Hip sonography in the newborn

    International Nuclear Information System (INIS)

    The authors report the data relative to 1507 cases studied with clinical and US examinations, in the neonatal period, in order to exclude hip dysplasia dislocation. US examination was carried out according to Graf's technique and the newborns were classified according to US hip type, to clinical examination and to possible risk factors. The patients were included in a protocol including orthopedic and US controls. Seventeen treated infants were considered as pathologic. Ten of them had IIc or D hips ar birth; the other 7, with IIa hips at birth, presented a X-ray pathologic hip after the 4th months of life. At about one year of age all infants could normally walk, excpet for one who was being treated with herness. No statistically significant differences were observed between the number of pathologic infants in the risk group (1.7%) and that in the no-risk group (0.8%). Clinical examination of the newborn has low sensitivity in detecting pathologic hips. On the basis of their results, thw authors belive US examination of the newborn to be a valuable screening method to diagnose hip dysplasia/dislocation. Moreover, Graf's morphologic method is the best one for US screening of the hip in the neonatal period

    Full Text Available Oculodentodigital dysplasia is a rare, autosomal dominant disorder with high penetrance and variable expressivity, caused by mutations in the connexin 43 or gap junction protein alpha-1 gene. It has been diagnosed in fewer than 300 people worldwide with an incidence of around 1 in 10 million. It affects many parts of the body, particularly eyes (oculo, teeth (dento, and fingers and/or toes (digital. The common clinical features include facial dysmorphism with thin nose, microphthalmia, syndactyly, tooth anomalies such as enamel hypoplasia, anodontia, microdontia, early tooth loss and conductive deafness. Other less common features are abnormalities of the skin and its appendages, such as brittle nails, sparse hair, and neurological abnormalities. To prevent this syndrome from being overlooked, awareness of possible symptoms is necessary. Early recognition can prevent blindness, dental problems and learning disabilities. Described here is the case of a 21-year-old male who presented to the ophthalmology outpatient department with a complaint of bilateral progressive loss of vision since childhood.

    Little data exists on the original morphology of acetabular dysplasia obtained from patients without radiographic advanced osteoarthritic changes. The aim of this study was to investigate the distribution and degree of acetabular dysplasia in a large number of patients showing no advanced degenerative changes using three-dimensional computed tomography (3DCT). Eighty-four dysplastic hips in 55 consecutive patients were studied. All 84 hips were in pre- or early osteoarthritis without radiographic evidence of joint space narrowing, formation of osteophytes or cysts, or deformity of femoral heads. The mean age at the time of CT scan was 35 years (range 15-64 years). 3D images were reconstructed and analyzed using recent computer imaging software (INTAGE Realia and Volume Player). Deficiency types and degrees of acetabular dysplasia were precisely evaluated using these computer software. The average Harris hip score at CT scans was 82 points. Twenty-two hips (26%) were classified as anterior deficiency, 17 hips (20%) as posterior deficiency, and 45 hips (54%) as lateral deficiency. No significant difference was found in the Harris hip score among these groups. The analysis of various measurements indicated wide variations. There was a significant correlation between the Harris hip score and the acetabular coverage (p < 0.001). Our results indicated wide variety of deficiency type and degree of acetabular dysplasia. Hips with greater acetabular coverage tended to have a higher Harris hip score. (orig.)

    Full Text Available Abstract Fibromuscular dysplasia (FMD, formerly called fibromuscular fibroplasia, is a group of nonatherosclerotic, noninflammatory arterial diseases that most commonly involve the renal and carotid arteries. The prevalence of symptomatic renal artery FMD is about 4/1000 and the prevalence of cervicocranial FMD is probably half that. Histological classification discriminates three main subtypes, intimal, medial and perimedial, which may be associated in a single patient. Angiographic classification includes the multifocal type, with multiple stenoses and the 'string-of-beads' appearance that is related to medial FMD, and tubular and focal types, which are not clearly related to specific histological lesions. Renovascular hypertension is the most common manifestation of renal artery FMD. Multifocal stenoses with the 'string-of-beads' appearance are observed at angiography in more than 80% of cases, mostly in women aged between 30 and 50 years; they generally involve the middle and distal two-thirds of the main renal artery and in some case also renal artery branches. Cervicocranial FMD can be complicated by dissection with headache, Horner's syndrome or stroke, or can be associated with intracerebral aneurysms with a risk of subarachnoid or intracerebral hemorrhage. The etiology of FMD is unknown, although various hormonal and mechanical factors have been suggested. Subclinical lesions are found at arterial sites distant from the stenotic arteries, and this suggests that FMD is a systemic arterial disease. It appears to be familial in 10% of cases. Noninvasive diagnostic tests include, in increasing order of accuracy, ultrasonography, magnetic resonance angiography and computed tomography angiography. The gold standard for diagnosing FMD is catheter angiography, but this invasive procedure is only used for patients in whom it is clinically pertinent to proceed with revascularization during the same procedure. Differential diagnosis include

    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.

  5. Retrospective analysis for genetic improvement of hip joints of cohort labrador retrievers in the United States: 1970-2007.

    Directory of Open Access Journals (Sweden)

    Yali Hou

    Full Text Available BACKGROUND: Canine Hip Dysplasia (CHD is a common inherited disease that affects dog wellbeing and causes a heavy financial and emotional burden to dog owners and breeders due to secondary hip osteoarthritis. The Orthopedic Foundation for Animals (OFA initiated a program in the 1960's to radiograph hip and elbow joints and release the OFA scores to the public for breeding dogs against CHD. Over last four decades, more than one million radiographic scores have been released. METHODOLOGY/PRINCIPAL FINDINGS: The pedigrees in the OFA database consisted of 258,851 Labrador retrievers, the major breed scored by the OFA (25% of total records. Of these, 154,352 dogs had an OFA hip score reported between 1970 and 2007. The rest of the dogs (104,499 were the ancestors of the 154,352 dogs to link the pedigree relationships. The OFA hip score is based on a 7-point scale with the best ranked as 1 (excellent and the worst hip dysplasia as 7. A mixed linear model was used to estimate the effects of age, sex, and test year period and to predict the breeding value for each dog. Additive genetic and residual variances were estimated using the average information restricted maximum likelihood procedure. The analysis also provided an inbreeding coefficient for each dog. The hip scores averaged 1.93 (+/-SD = 0.59 and the heritability was 0.21. A steady genetic improvement has accrued over the four decades. The breeding values decreased (improved linearly. By the end of 2005, the total genetic improvement was 0.1 units, which is equivalent to 17% of the total phenotypic standard deviation. CONCLUSION/SIGNIFICANCE: A steady genetic improvement has been achieved through the selection based on the raw phenotype released by the OFA. As the heritability of the hip score was on the low end (0.21 of reported ranges, we propose that selection based on breeding values will result in more rapid genetic improvement than breeding based on phenotypic selection alone.

    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.

    Objective To evaluate the results of rotational acetabular osteotomy (RAO) combined with debridement under arthroscope in the treatment of adult developmental dysplasia of the hip (DDH). Methods Between April 2002 and August 2007,24 cases (29 hips) of DDH were treated with RAO combined with debridement under arthroscope. There were 2 males (2 hips) and 22 females (27 hips) with an average age of 37.7 years (range, 21-50 years). The locations were the left hip in 7 cases, the right hip in 12 cases, and both hips in 5 cases. The course of hip pain was 8-216 months (median, 30.5 months). According to Crowe DDH classification, there were 24 hips of type I and 5 hips of type II. According to T8nnis hip osteoarthritis classification, there were 20 hips of stage I and 9 hips of stage II. Results The mean operation time was 150 minutes (range, 120-180 minutes); the mean intraoperative blood loss was 600 mL (range, 500-700 mL); and the mean postoperative drainage volume was 200 mL(range, 50-400 mL). All incisions healed by first intention. Twenty-four cases were followed up 4.5 years on average (range, 3-8 years). At last follow-up, daudication disappeared in 16 hips and was improved in 8 hips. The Harris hip score was improved from 79.4 ± 9.8 preoperatively to 95.1 ± 8.6 postoperatively, showing significant difference (t=2.467, P=0.010). The visual analogue scale (VAS) score was improved from 5.1 ± 0.8 preoperatively to 1.1 ± 0.6 postoperatively, showing significant difference (t=2.118, P=0.011).

    Introduction: Fibrous dysplasia is a rare benign disorder of the skeletal system characterized by fibro osseous proliferation with intervening areas of normal or immature bone in the intramedullary region. It can either be a monostotic (involves one bone) or a polyostotic (involves more than one bone) presentation and usually occurs equally in males and females. Deformities like scoliosis and shepherd’s crook deformity are frequently encountered in the polyostotic form. We report a rare manag...

  13. A contribution of quality assurance in veterinary radiography: further development and calibration of a test phantom to control the radiographic quality for diagnosis of the canine hip displasia

    International Nuclear Information System (INIS)

    The test phantom of PARISOT (1988), constructed in the form of a staircase was further developed for quality assurance in hip displasia photographing of dog. The original model of the staircase was made out of PVC could not be used because of the big size of the structures being photographed. The X-ray density of this material would have demanded a phantom 80 mm thick. A new staircase made out of plates copper, 0.1 mm thick (234 x 55 mm), with 18 steps and a basis plate, 20 mm projecting on each side, containing drill holes of 0.5 and 0.7 mm per step, was constructed. Using different recording data, this test phantom was simultaneously HD-photographed (HD-position I, focused screen, size of the cassette 30 x 40 cm) with the patient and the X-ray images were classified into three groups, too light, assessable and too dark by a recognized HD-expert. Than these X-ray images were assessed by 15 test subjects judging the visibility of the drillings in the basis plate. Summarizing these two judgements a nomogram was made, fixing the respective permissible upper limit of the visibility of the drill holes according to different diameters. In compliance with these limits the X-ray image can be judged with very high probability (> 95 %). The mounting of phantom below the screen offered a substantially improved possibility for evaluation. The division of a nomogram into a small cove area (ideal photograph) and into an area for still usable X-ray images is discussed. (author)

  15. Biomechanics of the Hip Capsule and Capsule Management Strategies in Hip Arthroscopy.

    Nepple, Jeffrey J; Smith, Matthew V

    2015-12-01

    Recent advances in our understanding of the function of the hip capsule have clarified its importance to normal hip function and kinematics. The iliofemoral ligament is the primary stabilizing structure for controlling anterior translation and external rotation of the hip, and is violated by the arthroscopic interportal capsulotomy. Microinstability of the hip occurring after surgical trauma remains a poorly defined clinical entity. In certain at-risk populations, capsular repair should be considered as part of an arthroscopic hip procedure to achieve optimal outcomes and avoid iatrogenic instability (dislocation or microinstability). Despite a lack of conclusive evidence-based indications, we recommend capsular repair in the settings of borderline hip dysplasia (or dysplastic variants such as increased femoral anteversion), hip hypermobility, connective tissue disorders, and traumatic or atraumatic instability. With careful attention to arthroscopic capsular management, adequate exposure can be achieved and reproducibly allow for an effective capsular repair when indicated. PMID:26524549

    2010-06-01

    Hip instability is becoming a more commonly recognized source of pain and disability in patients. Traumatic causes of hip instability are often clear. Appropriate treatment includes immediate reduction, early surgery for acetabular rim fractures greater than 25% or incarcerated fragments in the joint, and close follow-up to monitor for avascular necrosis. Late surgical intervention may be necessary for residual symptomatic hip instability. Atraumatic causes of hip instability include repetitive external rotation with axial loading, generalized ligamentous laxity, and collagen disorders like Ehlers-Danlos. Symptoms caused by atraumatic hip instability often have an insidious onset. Patients may have a wide array of hip symptoms while demonstrating only subtle findings suggestive of capsular laxity. Traction views of the affected hip can be helpful in diagnosing hip instability. Open and arthroscopic techniques can be used to treat capsular laxity. We describe an arthroscopic anterior hip capsular plication using a suture technique. PMID:20473129

  1. Polyostotic fibrous dysplasia

    International Nuclear Information System (INIS)

    Fibrous dysplasia is a benign fibro-osseous condition that is replacement of normal bone and marrow tissues by cellular fibrous tissue and immature bone, and it is divided into monostotic type and polyostotic type. Polyostotic fibrous dysplasia involves multiple bones, such as skull, jaw bones, femur and tibia. And it is also divided into two forms: the less severe Jaffe's type and the more severe Albright's syndrome. Clinically, it frequently occurs in the 2nd decade, and occurs more frequently in maxilla than in mandible. And the lesions of fibrous dysplasia tend to become static as skeletal maturity is reached. The authors experienced three cases of polyostosic fibrous dysplasia in the craniofacial area with the complaints of facial asymmetry due to painless swelling. And we discussed the clinical, radiological, and histopathological features of these cases with a brief review of the literatures.

    Renal dysplasia is a congenital anomaly with abnormal development of nephrotic and ductal structure and untreatable disease with absent renal function. To determine whether any consistent sonographic patterns exists,the sonograms of 27 pediatric patients with mastocytosis despotically kidney were reviewed. The diagnosis was proved by pathology in 16 cases and other radiologic imaging in 11 cases. In the classical multicystic despotically kidney(pelvoinfundibular atresia type, 10 cases), there were typical findings, such as absent communication between peripherally located variable sized cysts and presence of the largest cyst away from the renal hilum. One case was associated contralateral renal hydronephrosis. There cases were hydro nephrotic type which had medial location of the largest cyst with non communicating peripheral cysts. Segmental dysplasia with double collecting system and ureterocele (5 cases) and dysplasia due to parasite urethral valve (2 cases) showed hydronephrosis without identifiable peripheral cysts. Among the hypoplastic dysplastic kidney (7 cases) including ectopic kidneys (3cases), corticomedullary differentiation were hard to be identified in 2 cases. In conclusion, diagnosis of the renal dysplasia can be obtained by US only or US with other functional studies such as radionuclide scan(99mTc-DMSA or renogram) and IVP. US detection of renal dysplasia is easy, and US findings provide valuable information in the subsequent management

    To evaluate the diagnostic accuracy of MR imaging in the identification of labral and articular cartilage lesions in patients with acetabular dysplasia. Pre-operative MR imaging was performed on 27 hips in 25 consecutive patients (16 males, 9 females, age range 19-52 years, mean age 31.2 years) with radiographic evidence of acetabular dysplasia (centre-edge angle of Wiberg <20 degrees). The average duration of symptoms was 16.2 months. Two musculoskeletal radiologists assessed MR images in consensus for the presence of abnormality involving the acetabular labrum and adjacent acetabular articular cartilage. A high resolution, non-arthrographic technique was used to assess the labrum and labral chondral transitional zone. Surgical correlation was obtained in all cases by a single surgeon experienced in hip arthroscopy and ten patients with normal hip MRI were included to provide a control group. The acetabular labra in the dysplastic hips demonstrated abnormal signal intensity, and had an elongated appearance when compared with the control group (mean length 10.9 mm vs 6.4 mm). Morphological appearances in the labra included surface irregularity, fissures and cleft formation. MR imaging correctly identified the severity of chondral abnormality in 24 of 27 hips (89%) when compared with arthroscopic findings. MR imaging demonstrates an elongated labrum, focal intra-substance signal change and irregularity and fissuring of the margins in patients with acetabular dysplasia. Abnormality is also identified at the labral chondral transitional zone, where fissuring, focal clefts, chondral deficiency and subchondral cyst formation may be apparent. A high-resolution, non-arthrographic technique can provide an accurate preoperative assessment and evaluate the presence of premature osteoarthritis. (orig.)

    Full Text Available The aim of this study is to systematically review the literature with regards to surgical treatment of patients with hip joint osteochondromas, and to report our surgical management of three paediatric patients who had femoral neck or acetabular osteochondromas in association with acetabular dysplasia. We performed a systematic review using PubMed and Embase databases for all studies that reported surgical treatments for patients with peritrochanteric or acetabular osteochondroma with or without acetabular dysplasia. We also retrospectively reviewed three patients who were diagnosed with a hip osteochondroma in association with actetabular dysplasia. These patients were known to have hereditary multiple exostoses (HME. The systematic review revealed 21 studies that met our inclusion criteria. All studies were case reports and retrospective in nature and failed to conclude a uniform treatment plan. The three reported cases illustrate successful excision of hip osteochondromas and treatment of acetabular dysplasia. Early excision of hip osteochondromas might prevent acetabular dysplasia in HME patients. Routine radiographic pelvic survey at the time of diagnosis of HME is recommended for early detection of hip osteochondromas and acetabular dysplasia in these children.

    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.

    Age has been cited in a recent article as the largest predictor of both chondral and labral lesions in patients with hip dysplasia. But it was not surprising that there is also a direct relation between a small lateral center-edge angle, acetabular head index, and cartilage degeneration and an increased acetabular index and labral tears in patients with hip dysplasia. The severity of the congenital disease determines the severity of the intra-articular lesions. PMID:27495863

    Aim: To prove that bilateral hereditary micro-epiphyseal dysplasia (BHMED), first described by Elsbach in 1959, is a distinct disorder radiologically as well as clinically, compared with multiple epiphyseal dysplasia (MED). Material and Methods: We used the data of the revised pedigree with 84 family members, performed a medical history, physical examination and made a radiological evaluation for defining a clinical and radiological phenotype of BHMED family members. We used blood samples for genetic analysis. Results: Although there is a clear clinical picture of the dysplasia, the radiological signs are more reliable for making the diagnosis. Especially the typical deformity of the hip and knee joint are diagnostic for BHMED. By linkage analysis we excluded linkage with the three known MED-loci (EDM1, EDM2 and EDM3). Conclusion: BHMED is indeed an entity that is distinct from common multiple epiphyseal dysplasia (MED), clinically, as well as radiologically and genetically. (orig.) [German] Ziel: Es sollte dargelegt werden, dass sich eine vererbliche, laterale Mikro-Epiphysendysplasie (BHMED), Erstbeschreibung durch Elsbach 1959, klinisch, radiologisch und genetisch von einer mutiplen Epiphysendysplasie (MED) unterscheidet. Material und Methode: Anhand der Daten eines ueberarbeiteten Stammbaumes mit 84 Familienmitgliedern wurde der medizinische Werdegang rekonstruiert. Es erfolgte eine physische Untersuchung der Familienmitglieder. Schliesslich wurde eine radiologische Auswertung durchgefuehrt, um einen klinischen und radiologischen Phaenotyp der von BHMED betroffenen Familienmitglieder zu definieren. Fuer eine genetische Analyse wurden Blutproben entnommen. Ergebnisse: Obwohl es ein deutliches klinisches Bild einer Dysplasie gibt, sind die radiologischen Kennzeichen fuer die Diagnose zuverlaessiger. Insbesondere die typische Deformation der Huefte und des Kniegelenks ist diagnostisch fuer BHMED. Durch Linkage-Analyse konnte eine Verbindung zu den drei bekannten

    Full Text Available Arrhythmogenic right ventricular dysplasia is a hereditary cardiomyopathy characterized by structural and functional disorders in the right ventricle, which results in ventricular arrhythmias. Arrhythmogenic right ventricular dysplasia is one of the important causes of sudden cardiac death in young people and athletes. Structural disorders in arrhythmogenic right ventricular dysplasia are associated with fibrosis and fatty infiltration of the right ventricular myocardium. These changes lead to progressive dilatation and dysfunction of the right ventricle, as well as the occurrence of life-threatening ventricular arrhythmias.In 2010 The Task Force corrected the diagnostic criteria of the condition, which include large and small criteria from 6 different categories to make the diagnosis more accurate. ECG, EchoCG, MRI of the heart as well as myocardial biopsy play an important role in the diagnosis of the disease. Prognosis of the disease often depends on the timely prevention of sudden cardiac death – the implantation ofa cardioverter-defibrillator and optimal drug therapy of the symptomatic heart failure.

    Full Text Available Hip arthroscopy is a safe method for treating a variety of pathological conditions that were unknown until a decade ago. Femoroacetabular impingement is the commonest of these pathological conditions and the one with the best results when treated early on. The instruments and surgical technique for hip arthroscopy continue to evolve. New indications for hip arthroscopy has been studied as the ligamentum teres injuries, capsular repair in instabilities, dissection of the sciatic nerve and repair of gluteal muscles tears (injuries to the hip rotator cuff, although still with debatable reproducibility. The complication rate is low, and ever-better results with fewer complications should be expected with the progression of the learning curve.

    Full Text Available Total hip arthroplasty in degenerative pathology secondary to congenital dysplasia differentiates itself amongtotal arthroplasties by the frequent technical difficulties it poses and the site where it is performed. The existence of aform of congenital dysplasia that remained untreated or insufficiently treated in childhood leads to irreversibledeformities in adulthood. Partial or total loss of joint congruence causes, in time, degenerative changes with theimpairment of hip mobility and is associated with a number of progressive deformations (limb length discrepancy,abnormal rotation, asymmetric lesions, periarticular muscle failure, which gradually reduce the quality of the patient’slife. This study aims at investigating the incidence of prosthetic hip arthroplasty for osteoarthritis secondary todysplastic hip in the total number of arthroplasties, the age when surgery is performed, the type of deformity andprosthetic components used, and the postoperative and long-term functional results. The study was conducted on 110patients who received total hip arthroplasty due to osteoarthritis secondary to hip dysplasia, between 1994 and 2011, inthe Orthopaedics Trauma Department of the Rehabilitation Hospital of Iasi, the incidence being of 3.34% of the totalnumber of arthroplasties, with a prevalence of 65% under the age of 50 years. The functional results were assessed,according to the Harris-hip-score parameters, as good or very good in proportion of 82%. The complexity of the areawhere the total hip arthroplasty is performed requires a good management consisting of thorough preoperativeplanning, determining the operatory indication, and specialized and individualized medical recovery.

    Full Text Available OBJETIVO: Apresentar uma ampla revisão da literatura sobre displasia broncopulmonar, abordando novas definições, fisiopatologia, prevenção, tratamento, prognóstico e evolução. FONTE DOS DADOS: Foram selecionados os artigos mais relevantes sobre o tema, desde a sua descrição inicial, em 1967, pesquisados na MEDLINE. SÍNTESE DOS DADOS: A displasia broncopulmonar é considerada uma das principais causas de doença pulmonar crônica em lactentes. Está associada a hospitalizações freqüentes e prolongadas, especialmente por doenças pulmonares, altos índices de mortalidade e alterações no desenvolvimento neuropsicomotor e no crescimento pôndero-estatural. A patogênese é complexa e influenciada principalmente por prematuridade, infecção, oxigênio suplementar e ventilação mecânica. A prevenção envolve o acompanhamento pré-natal adequado, a prevenção do parto prematuro, o uso pré-natal do corticosteróide, a terapia de reposição de surfactante e o uso de estratégias ventilatórias "protetoras". O tratamento do paciente com displasia broncopulmonar demanda uma equipe multidisciplinar. Quando indicada, a suplementação de oxigênio é de extrema importância. Apesar de maior risco de morbimortalidade nos primeiros anos de vida, a evolução em longo prazo é favorável na maioria das vezes. CONCLUSÕES: A displasia broncopulmonar vem sendo profundamente estudada na tentativa de identificação das suas causas e possibilidades de prevenção e de tratamento. Ainda existem controvérsias quanto a esses assuntos e também em relação ao prognóstico desses pacientes, especialmente quando se trata da evolução tardia da "nova" displasia broncopulmonar.OBJECTIVE: To present a wide-ranging review of the literature on bronchopulmonary dysplasia, covering new definitions, pathophysiology, prevention, treatment, prognosis and progression.

    The recognition of hips at risk of displacement in children with cerebral palsy (CP) is a difficult problem for the orthopaedic surgeon. The Gross Motor Function Classification System (GMFCS) and head-shaft angle (HSA) are prognostic factors for hip displacement. However, reference values for HSA are lacking. This study describes and compares the development of HSA in normal hips and children with CP. We selected 33 children from a retrospective cohort with unilateral developmental dysplasia of the hip (DDH) (five boys, 28 girls) and 50 children (35 boys, 15 girls) with CP with GMFCS levels II to V. HSA of normal developing hips was measured at the contralateral hip of unilateral DDH children (33 hips) and HSA of CP children was measured in both hips (100 hips). Measurements were taken from the radiographs of the children at age two, four and seven years. The normal hip HSA decreased by 2° per year (p GMFCS levels II and III HSA decreased by 0.6° (p = 0.046) and 0.9° (p = 0.049) per year, respectively. The HSA did not alter significantly in GMFCS levels IV and V. Between the ages of two and eight years, the HSA decreases in normal hips and CP children with GMFCS level, II to III but does not change in GMFCS levels IV to V. As HSA has a prognostic value for hip displacement, these reference values may help the orthopaedic surgeon to predict future hip displacement in children with CP.

  20. Fibrous dysplasia and cherubism.

    Science.gov (United States)

    Bhattacharya, Surajit; Mishra, R K

    2015-01-01

    Fibrous dysplasia (FD) is a non-malignant fibro-osseous bony lesion in which the involved bone/bones gradually get converted into expanding cystic and fibrous tissue. The underlying defect in FD is post-natal mutation of GNAS1 gene, which leads to the proliferation and activation of undifferentiated mesenchymal cells arresting the bone development in woven phase and ultimately converting them into fibro-osseous cystic tissue. Cherubism is a hereditary form of fibrous dysplasia in which the causative factor is transmission of autosomal dominant SH3BP2 gene mutation. The disease may present in two distinct forms, a less severe and limited monostotic form, and a more aggressive and more widespread polyostotic form. Polyostotic form may be associated with various endocrine abnormalities, which require active management apart from the management of FD. Management of FD is not free from controversies. While total surgical excision of the involved area and reconstruction using newer micro-vascular technique is the only definitive treatment available from the curative point of view, but this can be only offered to monostotic and very few polyostotic lesions. In polyostotic varieties on many occasions these radical surgeries are very deforming in these slow growing lesions and so their indication is highly debated. The treatment of cranio-facial fibrous dysplasia should be highly individualized, depending on the fact that the clinical behavior of lesion is variable at various ages and in individual patients. A more conservative approach in the form of aesthetic recontouring of deformed bone, orthodontic occlusal correction, and watchful expectancy may be the more accepted form of treatment in young patients. Newer generation real-time imaging guidance during recontouring surgery adds to accuracy and safety of these procedures. Regular clinical and radiological follow up is required to watch for quiescence, regression or reactivation of the disease process. Patients must be

  2. Arrhythmogenic right ventricular dysplasia

    International Nuclear Information System (INIS)

    The arrhythmogenic right ventricular dysplasia is a condition predominantly well defined with arrhythmic events. We analyze three cases diagnosed by the group. These cases were presented as ventricular tachycardia with a morphology of left bundle branch block, presenting one of them aborted sudden death in evolution. The baseline electrocardiogram and signal averaging were abnormal in two of the three cases, like the echocardiogram. The electrophysiological study was able to induce in the three patients with sustained monomorphic ventricular tachycardia morphology of left bundle branch block. The definitive diagnosis was made by right ventriculography in two cases and magnetic resonance imaging in the other. Treatment included antiarrhythmic drugs in the three cases and the placement of an automatic defibrillator which survived a sudden death (Author)

    2003-01-01

    Histologic grading of esophageal biopsies remains the cornerstone of management in patients with Barrett esophagus. This remains true despite ongoing research into the genetic abnormalities that occur in the setting of intestinal metaplasia, dysplasia, and adenocarcinoma of the esophagus. As of this writing, there are no objective tests that can replace the pathologist's eyes in predicting prognosis in this setting. However, pathologists and clinicians are well aware that the histologic interpretation of biopsies is an inherently subjective practice. The validity of this exercise depends entirely on the experience of the pathologist. Having said that, two interobserver studies on the grading of dysplasia in Barrett esophagus suggest that, if published criteria are adhered to, the histologic grading of dysplasia is a useful tool in patient management. In this review, the updated pathologic criteria for each category of dysplasia are presented, and the results of two large interobserver variability studies are reviewed.

    2011-01-01

    Full Text Available The hereditary condition known as ectodermal dysplasia is characterized by the absence or defect of two or more ectodermally derived structures. The most commonly observed forms of ectodermal dysplasia are the hidrotic and hypohidrotic types; discrimination is based on the absence or presence of sweat glands. A case of 8-year-old male child with hypohidrotic ectodermal dysplasia with complete anodontia of primary as well as secondary dentitions is presented. The child had a short stature, low intelligent quotient (I.Q.,, and was underweight. The patient experienced episodes of high fever, was intolerant to heat, and did not sweat. He exhibited smooth and dry skin, sparse light-colored eyebrows. Dental clinicians can be the first to diagnose ectodermal dysplasia due to the absence of teeth.

  6. Primary abductor hip contracture as diagnostic, prognostic and therapeutic problem in child hip pathology

    2007-01-01

    Full Text Available Coxa obliqua represents a special functional entity in the pathology of the child hip. Authors have confirmed the results of S.L. Weissman and B. Strinovic which claimed that the abductor contracture of the hip was a primary congenital condition that developed as a result of intrauterine malposition, leading later to the contralateral adductor contracture. Critical period for the development of complications was between 6 and 8 month after birth, adductor contracture might keep persisting together with the development of acetabular dysplasia, and later on with ipsilateral subluxation. This malformation has usually been diagnosed within 3 and 6 months of age. It could be connected with some other signs of malposition, such as plagiocephaly, torticollis or infantile thoracic C scoliosis. For the diagnosis of coxa obliqua, the examination of hips in the prone position was very important and the ultrasonic and radiological examinations were crucial. The applied treatment used to be exclusively physical rehabilitation. Wide diapering has been contraindicated. In this study, we included 2,500 newborns, 1,300 boys and 1,200 girls (5,000 hips. In 22 cases of coxa obliqua (10‰, the excellent results were obtained in 96% of cases. In two unsuccessfully treated cases, a contralateral dysplasia developed, and in one untreated, subluxation. The authors are advocating a systematic and early detection and treatment of the primary coxa obliqua. .

    Skeletal dysplasia is a disorder of skeletal development characterized by abnormality in shape, length, a number and mineral density of the bone. Skeletal dysplasia is often associated with manifestation of other organs such as lung, brain and sensory systems. Skeletal dysplasias or dysostosis are classified with more than 400 different names. Enchondral bone formation is a coordinated event of chondrocyte proliferation, differentiation and exchange of terminally maturated chondrocyte with bone. Impaired enchondral bone formation will lead to skeletal dysplasia, especially associated with short long bones. Appropriate bone volume and mineral density are achieved by balance of bone formation and bone resorption and mineralization. The gene encoding fibroblast growth factor receptor 3 is responsible for achondroplasia, representative skeletal dysplasia with short stature. The treatment with growth hormone is approved for achondroplasia in Japan. Osteogenesis imperfecta is characterized by low bone mineral density and fragile bone. Data on the beneficial effect of bisphosphonate for osteogenesis imperfecta are accumulating. Osteopetrosis has high bone mineral density, but sometimes show bone fragility. In Japan as well as other countries, pediatrician treat larger numbers of patients with skeletal dysplasia with short stature and fragile bones compared to 20 years ago.

    2007-10-15

    A skeletal dysplasia with previously unreported features is presented. Its evolution was characterized by growth abnormalities of bones without involvement of other organs. Advanced bone age, increased stature and irregular epiphyseal ossification with stippling of the main long bones were documented. Physeal overgrowth was massive in the left proximal humerus and femur. Furthermore, the hip joint appeared fused with an abundant mass of pathological calcific tissue extending from the femur to the ilium. Pathological epiphyses were characterized by anarchic cartilaginous proliferation with multiple ossification centres, while lamellar bone apposition and remodelling were normal. The observed bone changes were different from those in any previously reported syndrome, metabolic defect or bone dysplasia. However, they clearly indicated a defect of endochondral ossification with some resemblance to phenotypes observed in dysplasia epiphysealis hemimelica. (orig.)

    2016-01-01

    Background: Total hip arthroplasty (THA) for poliomyelitis is a problematic procedure due to difficulty in positioning the cup of the prosthesis in the true acetabulum and the risk of dislocation after THA due to the low muscle tone. Methods: We herein present a case of bilateral hip pain with a history of poliomyelitis. Radiograph showed bilateral hip osteoarthritis caused by hip dysplasia due to residual poliomyelitis in right hip joint or developing dysplasia of the hip joint in left hip joint. THA was performed to bilateral hip joints. Results: Six years after bilateral THA, bilateral hip pain significantly improved. Additionally, the muscle strength on the paralyzed right side partially improved. However, the muscle strength on the non-paralyzed left side did not significantly improve. No complications related to the surgery were observed. Conclusion: Promising early results were obtained for THA in our patient with residual poliomyelitis. However, surgeons should pay attention to the potential development of complications concerning THA that may arise due to the residual poliomyelitis. PMID:27347238

    Dumont, Guillaume D

    2016-07-01

    Instability of the hip can manifest in a wide range of settings, with presenting symptoms including subtle discomfort at end range of motion or more dramatic dislocation of the joint. It can result from traumatic injury with dislocation or subluxation; atraumatic capsular laxity; structural bony abnormality, such as acetabular dysplasia; and iatrogenic injury. Initial treatment of the concentrically reduced joint often begins with physical therapy to strengthen dynamic stabilizers and to allow time for resolution of acute symptoms. Surgical treatment is aimed at repairing injured soft tissue structures, including static stabilizers, and addressing underlying bony structural deficiencies. PMID:27343395

    2013-02-01

    Full Text Available Canine degenerative myelopathy (DM is a progressive disease process that is diagnosed late in life and mainly affects the pelvic limbs. Factors that make an ante-mortem definitive diagnosis of DM include: an insidious onset and clinical manifestation that mimics other disease processes of the pelvic limbs (hip dysplasia, cranial cruciate ligament rupture, etc. or there may even be concurrent disease processes, old-age onset and lack of reliable diagnostic methods. Until recently, South African dog owners had to submit samples to laboratories overseas for genetic testing in order to confirm an affected dog (homozygous A/A and to aid in the ante-mortem diagnosis of DM. Only affected dogs have been confirmed to manifest the clinical signs of DM. This study aimed to verify whether genetic testing by a local genetic laboratory was possible in order to detect a missense mutation of the superoxide dismutase gene (SOD1 that is implicated in causing the clinical signs of DM. The study also aimed to detect and map the inheritance of this disease process in a local Boxer dog population where the pedigree of the sampled population was known. Venous blood collected from Boxer dogs using a simple random sampling technique. The samples were genotyped for the SOD1:c.118G>A polymorphism. Carrier and affected Boxer dogs were detected. A pedigree that demonstrated the significance of inheriting a carrier or affected state in the population was mapped. The present study concludes that genotyping of the missense mutation in Boxer dogs is possible in South Africa. There are carrier and affected Boxer dogs in the local population, making DM a plausible diagnosis in aged dogs presenting with pelvic limb pathology.

    Full Text Available Congenital Dislocation of Hip (CDH, is one of the most common congenital diseases in the orthopedic field. It is also known as Developmental Dysplasia of Hip. The condition can be diagnosed by clinical, ultrasonographic and radiological examination. Here we are reporting two days old male baby with congenital dislocation of right hip joint. The goal of treatment is to obtain a reduction to provide an optimal environment for femoral head and acetabular development. Early diagnosis is the most crucial aspect of the treatment of children with congenital dislocation of hip. If dislocation remains undiagnosed or neglected, the secondary pathological changes take place. Education of primary care colleagues, in making the diagnosis and prompt referral for management is recommended.

    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.

  6. Results of Chiari pelvic osteotomy for acetabular dysplasia in adults

    International Nuclear Information System (INIS)

    In an attempt to determine indications of Chiari pelvic osteotomy in acetabular dysplasia, postoperative outcome of hip joint (64 joints) was examined on the basis of findings of bone scintigraphy. The subjects were 61 patients with osteoarthrosis of hip joint who underwent preoperative bone scintigraphy. The follow-up period ranged from 2 years to 9 years and 7 months with a mean of 4 years and 9 months. According to X-ray findings, 37 osteoarthrosis joints were staged as early and 27 as progressive. Preoperative bone scintigraphic findings fell into three: (I) normal or slight hot type (33 joints), (II) hot type at the weighting part (16 joints), and (III) double hot type in the weighting part and inside part (15 joints). None of the patients had severe surgical complications such as deep-seated infection, neuroparalysis and pseudojoint. According to the clinical staging for hip joint function, 7 (47%) of 64 joints were judged as poor after osteotomy, belonging to type III. Deterioration of osteoarthrosis was seen in 11 joints (41%) on X-ray films. Of these, 9 had type III. In conclusion, Chiari pelvic osteotomy should not be indicated when type III is shown on bone scintigrams. (N.K.)

    Burke, Neil G

    2011-02-01

    Periacetabular osteotomy (PAO) is a very effective reconstructive procedure for treatment of acetabular dysplasia. An orthopaedic paediatric surgeon and a reconstructive hip arthroplasty surgeon performed this procedure together in the early phase of their learning curve and then performed it individually. The early clinical and radiographic results of 85 consecutive PAOs performed in this academic orthopaedic unit were reviewed. The mean Merle-d\\'Aubigné score increased from 12.4 preoperatively to 16 at follow-up. Pre-operatively 73 hips were anteverted and 12 were neutral or retroverted. The mean angle of Wiberg improved from 5 degrees to 21 degrees (p < 0.0001) in anteverted hips, and from 9 degrees to 30 degrees in neutral or retroverted hips. The mean angle of Lequesne and de Sèze improved from 6 degrees to 35 degrees (p < 0.0001) in anteverted hips, and in neutral or retroverted hips from 9 degrees to 30 degrees (p < 0.0001). The acetabular index improved from 26 degrees to 8 degrees (p < 0.0001) in anteverted hips, and from 21 degrees to 7 degrees (p < 0.0001) in neutral or retroverted hips. Over the 7 year period the blood loss and operative time improved from 2000 ml to 900 ml and 4 hours to 2 hours respectively. Four hips (four patients) required conversion to total hip replacement. The radiographic correction and improved clinical scores are similar to those in previous studies. This study shows a survival rate of 94% at 58 months following periacetabular osteotomy. The learning curve and the early results of this procedure performed in our academic unit are encouraging.

    Objective is to identify epidemiologic and radiologic criteria allowing specific diagnoses of tumors and tumor-like lesions in the hip region and pelvis, and to optimize pre-operative staging. Patients with pelvic tumors are usually older, and their tumors are larger relative to patients with tumors in extremities. The majority of tumors in the pelvis are malignant (metastases, myeloma, chondrosarcoma, Ewing-, osteo-, and MFH/fibrosarcoma), while those in the proximal femur are in majority benign (fibrous dysplasia, solitary bone cyst, and osteoid osteoma). Soft tissue masses in the thigh in the elderly are typically sarcomas without tumor specific signs. Common tumor-like lesions occurring in the hip and pelvis that can mimic neoplasm are: infections (including tuberculosis), insufficiency/avulsion fractures, cysts, fibrous dysplasia, aneurysmal bone cyst, Langerhans cell histiocytosis, and Paget's disease. Local MR staging is based on the compartmental anatomy. The psoas and gluteal muscles are easily invaded by sarcoma originating in the ileum. The pectineus muscle protects the neurovascular bundle at the level of the hip. The thigh is separated into three compartments, some structures (Sartorius muscle) cross borders between compartments. Immobile joints (SI-joints, osteoarthritic hip) are relatively easily crossed by sarcoma and giant cell tumor.

    Skeletal dysplasias are not uncommon entities and a radiologist is likely to encounter a suspected case of dysplasia in his practice. The correct and early diagnosis of dysplasia is important for management of complications and for future genetic counselling. While there is an exhaustive classification system on dysplasias, it is important to be familiar with the radiological features of common dysplasias. In this article, we enumerate a radiographic approach to skeletal dysplasias, describe the essential as well as differentiating features of common non-lethal skeletal dysplasias and conclude by presenting working algorithms to either definitively diagnose a particular dysplasia or suggest the most likely differential diagnoses to the referring clinician and thus direct further workup of the patient.

    Full Text Available Background. The S-ROM-A prosthesis has been designed for the Asian proximal femur with a small deformed shape and narrow canal. In this study, the clinical and radiological results using the S-ROM-A prosthesis for Japanese patients with severe deformity due to dysplasia and excessive posterior pelvic tilt were examined. Methods. 94 hips were followed up for a mean of 55 months, with a mean age at surgery of 61 years. The primary diagnoses were 94 coxarthritis cases, including 51 dysplasia and 37 primary OA, 1 avascular necrosis, 2 traumatic arthritis, and 3 Perthes disease. Thirty-one hips had been treated with osteotomy of the hip joints. Preoperative intramedullary canal shapes were stovepipe in 23 hips, normal in 51 hips, and champagne-flute in 5 hips. The maximum pelvic inclination angle was 56°. Results. The mean JOA score improved from 46 points preoperatively to 80 points at final follow-up. On radiological evaluation of the fixation of the implants according to the Engh classification, 92 (97% hips were classified as “bone ingrown fixation.” Conclusion. In primary THA, using the S-ROM-A prosthesis for Asian patients with proximal femoral deformity, even after osteotomy and with posterior pelvic tilt, provided good short- to midterm results.

    We report a case of a 75-year-old woman presenting a hitherto undescribed condition of bilateral second carpal row duplication. She was diagnosed in childhood with both Marfan and Ehlers-Danlos syndromes, with no clear evidence and no further medical follow-up. She presented throughout her life with various articular symptoms, which appeared to be compatible with a diagnosis of multiple epiphyseal dysplasia, and underwent several surgical procedures on her knees and hips. Most recently, she was reporting pain at the base of the fifth metacarpal bone of the left hand. X-ray images and computed tomography (CT) were obtained for exploration and showed a total second row duplication in both carpi, with a total number of 18 carpal bones in each wrist. PMID:26649258

    Cleidocranial dysplasia is a rare and autosomal dominant disorder characterized by aplasia or hypoplasia of the clavicles, an open fontanelle, dental abnormalities, and short stature. A 17-year-old female who presented with short stature and subsequent delay in eruption of permanent teeth is described. she showed the abnormal hypermobility of the shoulder, ocular hypertelorism and concave nasal bridge. Radiographs revealed the underdeveloped maxilla, defect of the cranium in the fontanelle region, and aplasia of the clavicles. Characteristically, panoramic view revealed near parallel-sided borders of the ascending ramus and downward curvature of the zygomatic arch with hypoplasia. The prolonged retention of deciduous teeth with delayed eruption of permanent teeth and multiple embedded supernumerary teeth were striking. Radiographic and clinical investigations revealed Cleidocranial dysplasia.

    Andersen, P.E. Jr.; Schantz, K.; Bollerslev, J.; Justesen, P.

    Multiple epiphyseal dysplasia tarda (MEDT) and spondylo-epiphyseal dysplasisa tarda (SEDT) are genetically transmitted conditions affecting the hips, which may resemble bilateral Legg-Perthes disease (LPD). Misdiagnoses are not uncommon, with serious implications for treatment, prognosis and genetic counseling. An epidemiologic study of MEDT and SEDT in a well-defined population of 453 921 persons in Denmark was performed. A population prevalence of 0.7 per 100 000 inhabitants with SEDT and 4.0 per 100 000 inhabitants with MEDT was found. Distinguishing features between MEDT, SEDT and bilateral LPD based on radiologic findings in the hips, other joints, and spine were ascertained. Bilateral LPD is always asymmetric, exhibits patches of increased density in the epiphyses and often metaphyseal cyst-like changes. No spinal lesion or affection of other joints is present, and the acetabula are normal. In MEDT and SEDT the capital femoral epiphyses are symmetrically flattened, fragmented and uniformly slightly sclerotic. Generalised platyspondyly is a constant finding in SEDT.

    Multiple epiphyseal dysplasia (MED) is an osteochondrodysplasia characterized clinically by mild short stature and early-onset degenerative joint disease and radiographically by epiphyseal hypoplasia/dysplasia. MED is genetically heterogeneous, with autosomal dominant cases resulting from mutations in at least three genes: the cartilage oligomeric matrix protein (COMP) gene (EDM1) and the COL9A2 (EDM2) and COL9A3 (EDM3) genes of type IX procollagen. We present here a comparison of the radiographic phenotypes of MED patients with type IX collagen gene mutations and those with COMP gene mutations. We reviewed radiographs from two patients with MED produced by COMP mutations, two families with COL9A2 mutations, and one family with a mutation in COL9A3. The data demonstrated that the patients with type IX collagen defects had more severe joint involvement at the knees and relative hip sparing, while the patients with COMP mutations had significant involvement at the capital femoral epiphyses and irregular acetabuli. This pattern of joint involvement was consistent regardless of overall degree of severity of the phenotype. (orig.)

    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.

    Background: Various qualitative and quantitative radiological geometrical parameters can be of great help when assessing dysplasia of the hip joint and in understanding developmental processes of the infant hip. There are few data on the normal values of the hip joint at different ages. Objective: To perform radiographic measurements on hip joints considered to be anatomically normal and to provide data for each age group, thus describing features of the radiographic development of the hip. Materials and methods: Radiographs were examined from 355 children (age 0-16 years) undergoing examination for scoliosis (long film), urography or plain abdominal radiography. Qualitative and quantitative signs were observed and measured, focusing on the Hilgenreiner, Wiberg and Idelberger angles and the decentric distance. Results: Before the age of 9 years measurable data from neighbouring age groups differed significantly, indicating typical radiological changes of the joint. For the same age range, qualitative changes could also be observed. After 9 years of age, radiological development of the normal hip joint during childhood is much slower. (orig.)

    Fibrous dysplasia is a benign skeletal disorder of unknown aetiology. Fibrous dysplasia characteristically involves the fibrous replacement of portions of the medullary cavities of a single bone (monostotic) or multiple bones (polyostotic). Bones typically involved include the femurs, tibiae, ribs and maxillae. The polyostotic form may be accompanied by skin pigmentation and endocrine abnormalities (McCune Allbright Syndrome). Radiological findings in fibrous dysplasia are variable, ranging from completely radiolucent to radio-opaque lesions, depending on the amount of fibrous or osseous tissue deposited in the medulla. The most common radiographic finding is that of a ground glass-like semi-opaque lesion. Case reports on scintigraphic manifestation of fibrous dysplasia are scanty. We present radiological and scintigraphic findings of polyostotic fibrous dysplasia in a young male. (authors). 3 refs., 1 fig.

    We report on a 4-year-old boy with craniometadiaphyseal dysplasia (CMDD), wormian bone type. Component manifestations include a large head with prominent forehead, skull changes showing multiple wormian bones, wide long tubular bones without the usual metaphyseal flare, wide and short tubular bones without the normal diaphyseal constriction, and wide ribs and clavicles. In addition to these findings, the propositus, his brother, his father, and a paternal aunt all have parietal protuberances, which seem not related to CMDD. Parental consanguineity supports the autosomal recessive transmission of the condition. PMID:9605592

    2006-10-01

    Full Text Available Abstract Background Developmental dysplasia of the hip (DDH is a condition in which bone growth irregularities subject articular cartilage to higher mechanical stresses, increase susceptibility to subluxation, and elevate the risk of early osteoarthritis. Study objectives were to calculate three-dimensional cartilage contact stresses and to examine increases of accumulated pressure exposure over a gait cycle that may initiate the osteoarthritic process in the human hip, in the absence of trauma or surgical intervention. Methods Patient-specific, non-linear, contact finite element models, constructed from computed tomography arthrograms using a custom-built meshing program, were subjected to normal gait cycle loads. Results Peak contact pressures for dysplastic and asymptomatic hips ranged from 3.56 – 9.88 MPa. Spatially discriminatory cumulative contact pressures ranged from 2.45 – 6.62 MPa per gait cycle. Chronic over-pressure doses, for 2 million cycles per year over 20 years, ranged from 0.463 – 5.85 MPa-years using a 2-MPa damage threshold. Conclusion There were significant differences between the normal control and the asymptomatic hips, and a trend towards significance between the asymptomatic and symptomatic hips of patients afflicted with developmental dysplasia of the hip. The magnitudes of peak cumulative contact pressure differed between apposed articular surfaces. Bone irregularities caused localized pressure elevations and an upward trend between chronic over-pressure exposure and increasing Severin classification.

    2012-04-01

    Full Text Available Leishmaniasis is the third most important vector-borne disease worldwide. Visceral leishmaniasis (VL is a severe and frequently lethal protozoan disease of increasing incidence and severity due to infected human and dog migration, new geographical distribution of the insect due to global-warming, co-infection with immunosuppressive diseases and poverty. The disease is an anthroponosis in India and Central Africa and a canid zoonosis (ZVL in the Americas, the Middle East, Central Asia, China and the Mediterranean. The ZVL epidemic has been controlled by one or more measures including the culling of infected dogs, treatment of human cases and insecticidal treatment of homes and dogs. However, the use of vaccines is considered the most cost-effective control tool for human and canine disease. Since the severity of the disease is related to the generation of T-cell immunosuppression, effective vaccines should be capable of sustaining or enhancing the T-cell immunity. In this review we summarize the clinical and parasitological characteristics of ZVL with special focus on the cellular and humoral canine immune response and review state-of-the-art vaccine development against human and canine visceral leishmaniasis. Experimental vaccination against leishmaniasis has evolved from the practice of leishmanization with living parasites to vaccination with crude lysates, native parasite extracts to recombinant and DNA vaccination. Although more than 30 defined vaccines have been studied in laboratory models no human formulation has been licensed so far; however three second-generation canine vaccines have already been registered. As expected for a zoonotic disease, the recent preventive vaccination of dogs in Brazil has led to a reduction in the incidence of canine and human disease. The recent identification of several Leishmania proteins with T-cell epitopes anticipates development of a multiprotein vaccine that will be capable of protecting both humans

    2000-04-01

    Objective: To investigate the diagnostic value and the impact on surgical type classification of three-dimensional (3D) images for pre-surgical evaluation of dysplastic hips. Materials and methods: Three children with a different surgical type of hip dysplasia were investigated with helical computed tomography. For each patient, two-dimensional (2D) images, 3D, and a stereolithographic model of the dysplastic hip were generated. In two separate sessions, 40 medical observers independently analyzed the 2D images (session 1), the 2D and 3D images (session 2), and tried to identify the corresponding stereolithographic hip model. The influence of both image presentation (2D versus 3D images) and observer (degree of experience, radiologist versus orthopedic surgeon) were statistically analyzed. The SL model choice reflected the impact on surgical type classification. Results: Image presentation was a significant factor whereas the individual observer was not. Three-dimensional images scored significantly better than 2D images (P=0.0003). Three-dimensional imaging increased the correct surgical type classification by 35%. Conclusion: Three-dimensional images significantly improve the pre-surgical diagnostic assessment and surgical type classification of dysplastic hips.

    Objective. To present the magnetic resonance (MR) imaging findings in patients with labral cysts adjacent to the acetabulum and to examine their association with hip pathology. Design. MR images and conventional radiographs of seven patients with paralabral cysts were retrospectively reviewed by three musculoskeletal radiologists. Patients. The patients included three men and four women with hip pain, ranging in age from 29 to 82 years. Two patients had developmental dysplasia of the hip and six had a history of remote trauma/dislocation. Clinical history and follow-up were obtained in all patients. Surgery was performed on one patient. Results and conclusions. Paralabral cysts were located in the posterosuperior aspect of the hip joint in five patients and in the anterior aspect in two patients. A tear of the adjacent acetabular labrum was confirmed surgically in one patient, and in all patients the MR features suggested the presence of an abnormal labrum. Osteoarthritis was observed in three patients and there was associated subchondral cyst formation in the acetabulum adjacent to the cyst in three patients. The paralabral cyst of the hip is well visualized on MR imaging and is seen in patients with a predisposition to labral pathology. (orig.). With 3 figs., 1 tab.

    There are no published studies focused on the potential crosstalk between steroid hormones and EGF in canine mammary tumourigenesis. The objective was to investigate the role of EGF in canine mammary tumours (CMT) and the relationship with steroid hormones. Sixty-three CMT (39 malignant including 10 inflammatory mammary carcinomas (IMC); 19 benign and 5 dysplasias), and 13 normal mammary glands from dogs without history of neoplastic disease were analysed. Levels of EGF and steroid hormones [progesterone (P4); 17beta-estradiol (E2); androstenedione (A4) and dehydroepiandrosterone (DHEA)], were analysed by EIA in CMT homogenates. Levels of EGF were significantly higher in malignant compared with benign tumours, dysplasias and normal mammary glands (pIMC presented the highest EGF levels, with statistical significant difference between IMC and non-IMC cases (pIMC and IMC), a strong correlation was observed between EGF and: P4 (r=0.452; p=0.003); E2 (r=0.624; p=0.023); A4 (r=0.496; p=0.038); DHEA (r=0.431; p=0.005). These results suggest that EGF is implicated in canine mammary tumourigenesis. The positive correlation observed, opens an interesting perspective of interaction that should be further investigated.

    Pain is the main reason inducing patients to undergo surgery and persistence of pain after the operation is a major concern, both for the patient and the surgeon. Up to 10% of patients report pain five years after hip arthroplasty. An analysis of the literature reveals numerous causes of pain localised to the replacement hip. In assessing a painful hip it is fundamental to arrive at a definite diagnosis before starting any treatment. Intrinsic causes can be identified, such as unrecognised as...

    We describe 27 individuals of 7 families related to each other with high probability who showed manifestations of ectodermal dysplasia and other anomalies affecting females as severely as males with variable expressivity. All parents were normal. These families were detected in a relatively isolated and inbred population with very small neighbouring communities from a Caribbean Sea island, Margarita Island, in Northeastern Venezuela (Nueva Esparta State). The clinical picture common to all patients could not be classified within the heterogeneous group of known ectodermal dysplasias and the published cases do not resemble our patients. We believe that this condition constitutes a newly recognized autosomal recessive dysplasia/malformation syndrome of ectodermal dysplasia. PMID:1776626

    Ectodermal Dysplasia Syndrome (EDS) is mainly X-linked inherited disorder with male predominance. According to Lyon hypothesis, female patients may show partial expression of EDS. Oral findings include hypodontia, rarely anodontia, protuberant lips, hyposalivation, conical teeth and loss of vertical dimension. The alveolar process fails to develop in the three dimensions. Such patients present a challenge to dental treatment due to an irregular residual ridge. This case report presents oral, functional and aesthetic rehabilitation of a 21-year-old female diagnosed with EDS using implants in the anterior maxilla at the sites of the canines bilaterally. Following, implant placement, it was noted that implant in the region of right canine was labially inclined compared to implant in the region of left canine, but both were centered in the ridge. To manage non-parallelism, one-piece titanium framework was fabricated using computer numeric controlled (CNC) machine. Subsequently, tooth and gingival shade ceramics were fired to simulate natural teeth and compensate for gingival deficiency respectively. The treatment described here restored patient's aesthetics, function, self-confidence and status in society. PMID:27437373

    Full Text Available Ectodermal dysplasia-skin fragility syndrome (EDSFS is a rare autosomal recessive genodermatosis first described in 1997 by Mc Grath. EDSFS results from loss of function mutations in plakophilin-1 (PKP1. PKP1 is a structural component of desmosomes, cellcell adhesion complexes. It is also found as a nuclear protein in several cell types that are lack of desmosomes. In skin, however, PKP1 expression is confined mainly to suprabasal keratinocytes and the outer root sheath of hair follicules. Loss of function mutation in PKP1 leads to extensive skin fragility, bullae and erosions following minor trauma, focal keratoderma with painful fissures, alopecia, and nail dystrophy. In some patients hypohidrosis may also be seen. EDSFS is now considered as a specific suprabasal form of epidermolysis bullosa simplex. In this report we describe a 20 year old EDSFS case.

The mass had grown for 6 years, after she had sustained a head injury at the age of 6, and was located directly under a previous wound. Skull X-ray Photograph (xp, computed tomography (CT, and magnetic resonance imaging (MRI showed a bony defect and cystic changes in the skull corresponding to a subcutaneous mass. Bone scintigraphy revealed partial accumulation. The patient underwent total removal of the skull mass, and the diagnosis from the pathological findings of the cyst wall was fibrous dysplasia (FD. The radiographic findings for cystic cranial FD can be various. Progressive skull disease has been reported to be associated with head trauma, but the relationship between cranial FD and head trauma has not been previously reported. Previous studies have suggested that c-fos gene expression is a key mechanism in injury-induced FD.

    Fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory vascular disease that most commonly affects the renal and extracranial carotid arteries. We present 3 cases of renal infarction complicating renal artery FMD in 42-, 43-, and 46-year-old females and provide a comprehensive review of the literature on this topic. In our patients, oral anticoagulation therapy was used to treat all cases of infarction, and percutaneous angioplasty was used nonemergently in one case to treat refractory hypertension. All patients remained stable at 1-year follow-up. This is consistent with outcomes in previously published reports where conservative medical management was comparable to surgical and interventional therapies. Demographic differences may also exist in patients with renal infarction and FMD. A higher prevalence of males and a younger age at presentation have been found in these patients when compared to the general population with FMD.

    Congenital dysplasia of the humerus is very rare. It is characteristically seen in omodysplasia and has also been reported as one of the associated features of Larsen's syndrome. We report a 4-year-old girl with bilateral humero-ulnar dysplasia, with dislocation of the elbows, facial dysmorphism, ball-and-socket ankles and foot deformities. Although the elbow dysplasia is similar to that seen in Larsen's syndrome, other pathognomic features of Larsen's syndrome were absent. The changes seen in the elbows in this patient are also different from those encountered in omodysplasia. We believe that this condition may be a distinct form of skeletal dysplasia hitherto undescribed. (orig.)

    A normal hip has a natural tendency toward stability because of both osseous and soft tissue structures. Hip motion is primarily rotational around a center of rotation. When the femoral head and its center of rotation translate, with or without rotation, the inherent stability of the femoroacetabular articulation may be lost. The spectrum of hip instability ranges from subtle microinstability to traumatic dislocation. Microinstability may be the cause or the effect of several other hip pathologies. Soft tissue contributions to stability include the static capsule, dynamic musculotendinous units, and underlying generalized connective tissue (eg, Ehlers-Danlos). Osseous contributions include multiple femoral and acetabular radiographic coverage parameters. Iatrogenic contributions include an unrepaired capsulotomy, overresection of the acetabular rim (iatrogenic dysplasia), overresection of cam osteochondroplasty, iliopsoas tenotomy, labral debridement, and ligamentum teres debridement. Patients with hip microinstability often have deep groin pain, exhibited by a C sign. These patients frequently participate in flexibility sports and activities, such as ballet, gymnastics, figure skating, and martial arts. On physical examination, generalized hypermobility syndromes should be assessed, as should loss of log-roll external rotation recoil, excessive abduction, trochanteric-pelvic impingement, and abductor fatigue. Standard imaging, including plain radiographs, magnetic resonance imaging, and computed tomography, should be analyzed for all causes of hip pain. A new plain radiograph, the splits radiograph is introduced here, consistently showing lateral femoral head translation and creation of a vacuum sign, showing hip microinstability. The splits radiograph is illustrated in a 22-year-old female dancer who presented with bilateral deep anterolateral groin pain. PMID:26730687

  16. Differentiating subluxation from developmental dislocation of the hip

    Full Text Available The radiological and clinical picture of a developmental hip dislocation and a severe subluxation are identical. According to Leveuf and Wiberg the diagnosis can only be made by arthrography. The differential diagnosis is critical, as treatment differs dependent on the diagnosis. In this study, the diagnosis of subluxation was based on a plain radiograph of the pelvis. A radiograph of the pelvis with the hips abducted at least 45° and internally rotated (AIR view was used to differentiate these two entities. In subluxations, the femoral head will relocate into the acetabulum with perfect or near perfect reconstitution of the Shenton’s line. It will fail to do so in true dislocations. Five patients, mean age 14.6 months (range 9 to 20 months, presented with delayed diagnosis of hip dysplasia. The examination revealed minimal or no limitation of hip abduction, a leg length discrepancy, and a Trendelenburg gait in the three walking age girls. The radiograph suggested a hip dislocation. The diagnosis of hip subluxation was based on the relocation of the femoral head with the abduction/internal rotation radiograph. All were successfully treated with an Ilfeld abduction splint. None had examination with general anesthesia, arthrograms, traction or immobilization in spica cast. Avoiding over diagnosis of hip dislocation in cases of subluxation is important. This is necessary to prevent overtreatment and to accurately assess the results of treatment. The abduction/internal rotation view may achieve this goal while avoiding diagnostic and therapeutic procedures, such as arthrograms, cast immobilization and surgery.

The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus. Though anophthalmia can be diagnosed clinically, imaging plays a crucial role in delineating the associated anomalies. In addition, often clinical anophthalmia may prove to be severe microphthalmia on imaging. We describe the imaging findings in an infant with bilateral anophthalmia and septo-optic dysplasia.

    Saul-Wilson syndrome (SWS) is a rare congenital skeletal syndrome characterized by postnatal onset of short stature, relative microcephaly, frontal bossing, prominent eyes with shallow orbits, midface hypoplasia, cataract, and generalized skeletal changes, including spondylar dysplasia, overtubulation of the long bones with metaphyseal flaring and megaepiphyses, coxa valga, elbow deformity, and brachydactyly. We describe a boy with the overall clinical and radiological features fitting the characteristics of SWS, although cataract, elbow deformity, and overt brachydactyly were not seen. He presented with painful hip joint due to hip subluxation in late childhood, which exacerbated with age and ultimately, required surgical intervention. Awareness of this orthopedic complication in SWS is essential in the management of patients with SWS. PMID:26239279

    Highlights: • We evaluated a possible screening method for trochlea dysplasia. • 3D ultrasound was used to perform the measurements on standardized axial planes. • The evaluation of the technique showed comparable results to other studies. • This technique may be used as a screening technique as it is quick and easy to perform. - Abstract: Femoro-patellar dysplasia is considered as a significant risk factor of patellar instability. Different studies suggest that the shape of the trochlea is already developed in early childhood. Therefore early identification of a dysplastic configuration might be relevant information for the treating physician. An easy applicable routine screening of the trochlea is yet not available. The purpose of this study was to establish and evaluate a screening method for femoro-patellar dysplasia using 3D ultrasound. From 2012 to 2013 we prospectively imaged 160 consecutive femoro-patellar joints in 80 newborns from the 36th to 61st gestational week that underwent a routine hip sonography (Graf). All ultrasounds were performed by a pediatric radiologist with only minimal additional time to the routine hip ultrasound. In 30° flexion of the knee, axial, coronal, and sagittal reformats were used to standardize a reconstructed axial plane through the femoral condyle and the mid-patella. The sulcus angle, the lateral-to-medial facet ratio of the trochlea and the shape of the patella (Wiberg Classification) were evaluated. In all examinations reconstruction of the standardized axial plane was achieved, the mean trochlea angle was 149.1° (SD 4.9°), the lateral-to-medial facet ratio of the trochlea ratio was 1.3 (SD 0.22), and a Wiberg type I patella was found in 95% of the newborn. No statistical difference was detected between boys and girls.

  5. Does the gestation age of newborn babies influence the ultrasonic assessment of hip condition?

    Directory of Open Access Journals (Sweden)

    Simić Slavica

    2009-01-01

    Full Text Available Introduction. Ultrasound represents a method of examination of hips of newborn babies capable of defining hip condition and distinguishing stable and unstable hips based on morphological elements. It is accepted in a large number of countries as a method of examination of high risk newborns, or as a method of systematic screening. Objective. The objective of this study was to investigate correlation between ultrasonically estimated hip maturity and respective gestation maturity both in premature and term-born babies, and to investigate the influence of different delivery types on hips condition. Methods. In our study 2045 patients, 1141 males and 904 females, were examined in at the Institute of Neonatology over a period of 5 years. The average age was 34.04 gestation weeks. There were significantly more premature (1698 or 83.03% than term-born babies (347 or 16.97%. Ultrasound hip examination, as a screening method, was carried out according to Graf. It was followed by clinical examination. Results were analyzed by appropriate statistical methods (χ2-test, one-way ANOVA, multifactor ANOVA. Results. The overall frequency of unstable hips was 3.2%, 1.88% in males and 4.87% in females (p<0.05. 96.8% babies had stable hips, out of which 35.21% were mature and 61.59% immature. In the study of the breech presentation, out of 183 babies, unstable hips were found in 1.58% of male cases, and in 10.23% of female cases. Conclusion. Clinical screening of developmental dysplasia of the hip is insufficient for early diagnosis and decision about the treatment of premature babies. The high frequency of unstable hip type IIc (risky and IId (decentralized in premature babies requires early diagnosis and therapy. Wide swaddling for prematures should be applied up to eight months of age. Gentle manipulation is necessary while nursing and conducting physiotherapy of a premature baby.

  6. Total hip arthroplasty

    Directory of Open Access Journals (Sweden)

    Slavković Nemanja

    2012-01-01

    Full Text Available Total hip arthroplasty is most common reconstructive hip procedure in adults. In this surgery we replace some parts of the upper femur and acetabulum with biocompatible materials. The main goal of this surgery is to eliminate pain and regain full extent of joint motion, maintaining hip stability. Surgical technique, biomaterials, design of the prosthesis and fixation techniques have evolved with time adjusting to each other. After total hip arthroplasty patients’ quality of life should be improved. There are many various postoperative complications. Some of them are fatal, and some are minor, which may become manifested years after surgery. Each next surgical procedure following previous hip surgery is associated with considerably lower chances to be successful. Therefore, in primary total hip arthroplasty, preoperative evaluation and preparation of patients are essential. Every orthopaedic surgeon needs to improve already adopted surgical skills applying them with precision and without compromise, with the main goal to achieve long-term durability of the selected implant. The number of total hip arthroplasties will also increase in future, and newer and higher quality materials will be used.

The entire coding region of COL2A1, including the flanking intron regions, was analyzed with PCR and direct sequencing. The stature of the subjects ranged from extremely short to within normal height range. Hip deformity and advanced osteoarthritis were noted in all the subjects, ranging from severe coxa plana to mild acetabular dysplasia. Atlantoaxial subluxation combined with a hypoplastic odontoid process was found in three of the subjects. Various degrees of platyspondyly were confirmed in all subjects. Genetically, a novel COL2A1 mutation (c.1349G>C, p.Gly450Ala) was identified in all the affected family members; however, it was not present in the one unaffected family member tested. We described a family with spondyloepiphyseal dysplasia and a novel COL2A1 mutation (c.1349G>C, p.Gly450Ala). Phenotypes were diverse even among individuals with the same mutation and within the same family. PMID:27274858

  8. Pathogeny and natural history of congenital dislocation of the hip.

    Based on a review of the literature, the authors have made a critical study of several etiological factors. Endogenous factors such as acetabular dysplasia, increased anteversion of the femoral neck, and capsular laxity support the genetic theory but are neither constant nor necessary and are only facilitating factors. The major factor seems to be a mechanical one linked to the position in the uterus: hyperflexion with adduction and external rotation constituting the dislocating foetal posture combined with abnormal pressure on the greater trochanter and leading to expulsion of the head upward and backward. This theory can explain the natural history of C D H which is first, at birth a hip instability followed by two possible evolutions: either persistent luxation becoming irreducible or spontaneous stabilisation leading sometimes to complete healing or to residual abnormalities (subluxation or dysplasia). This concept suggests practical conclusions: the importance of an early diagnosis, the selection of the signs of the hip at risk, the pattern of prevention, the role for non-clinical investigations, the principles of the treatment based on postures, the indications for the different types of treatment.

    Full Text Available Vertebroplasty of the axis is a challenging procedure, and little is known about its therapeutic outcome. Cervical fibrous dysplasia with a distinct cyst is a rare entity and few cases have been reported in the literature. A 55-year-old man with fibrous dysplasia of axis presented with severe neck pain and left arm since six months. Computed tomography and magnetic resonance imaging revealed an expansile, destructive lesion involving the axis, and no spinal cord. He was submitted to retropharyngeal surgery and the lesion was fulled by vertebroplasty. Microscopic examination was consistent with the diagnosis of monostotic fibrous dysplasia. After the surgery no recurrence was observed. The patient had remarkable improvement in clinical relief of neck pain at 1-year follow-up. Although there are descriptions of vertebral fibrous dysplasia, this is the 13th case of monostotic fibrous dysplasia of the cervical spine, and the 3rd case of the axis described in the literature. The unique case who had treated with ope vertebroplasty.

    Full Text Available Harsh Mohan1, Preeti Mittal1, Irneet Mundi1, Sudhir Kumar21Department of Pathology, 2Department of Orthopedics, Government Medical College, Sector 32, Chandigarh, IndiaAbstract: Fibrous dysplasia of the bones is an uncommon congenital skeletal disorder that is found equally in both genders and is not inherited. Its etiology has been linked to an activating mutation of Gsα and the downstream effects of the resultant increase in cAMP. Fibrous dysplasia is categorized as either monostotic or polyostotic, and may occur as a component of McCune-Albright syndrome or the rare Mazabraud syndrome. Long bones, skull bones, and ribs are the most commonly affected bones. The radiological picture is somewhat variable, including a ground-glass appearance, expansion of the bone, and sclerosis surrounding the lesion. Histologically, fibrous dysplasia shows irregularly-shaped trabeculae of immature, woven bone in a background of variably cellular, loosely arranged fibrous stroma. It may be complicated by pathologic fracture, and rarely by malignant transformation. This review examines interesting issues surrounding the etiology of fibrous dysplasia, its clinical and laboratory manifestations, radiological picture, utility of bone biopsy, gross and microscopic pathology, complications, and its differential diagnostic considerations.Keywords: fibrous dysplasia, McCune-Albright syndrome, monostotic form, polyostotic form

    Full Text Available The word dysplasia originates from ancient Greek words dys (anomalous and plasia (formation. Skeltal dysplasia (SD is a heterogeneous group of congenital anomalies characterized by abnormalities in the development of the bone and cartilage tissue. This results in mark disproportion of the long bones, the spine and fetal head relation to the trunk. Perinatal lethal skeletal dysplasia leads to still birth or early neonatal death due to pulmonary hypoplasia. 30 yrs old G3P3L2 at 32 weeks presented with leaking per vaginum. Her serial scan was done as she had previous stillborn male child with short limbs. Her antenatal scan revealed short limbs from 24 weeks. From18 weeks to 24 weeks she did not underwent any sonography. She went into spontaneous labor and delivered still born male baby with clinical and radiological features suggestive of skeletal dysplasia. Skeletal dysplasia can be diagnosed on antenatal 2 D ultrasound from 14 - 16 weeks onwards. Prenatal genetic testing should be done to diagnose the genetic anomaly and patient should be referred to higher institute for this test. Even if genetic test not done even then termination of pregnancy should be considered based on ultrasound diagnosis especially with family history because of poor fetal prognosis and long term morbidity if survived.

    2010-01-01

    Background The order and mechanism of pathological changes in acetabular dysplasia are still unclear. This study investigated cartilage changes in rabbit acetabular dysplasia models at different ages.Methods Twenty-seven 1-month-old New Zealand rabbits underwent cast immobilization of the left hind limb in knee extension. Serial acetabular dysplasia models were established by assessment of the acetabular index and Sharp's angle on radiographs. The thickness of the acetabular cartilage was measured under a microscope, and fibrosis was observed. Ultrastructural changes were investigated with scanning electron microscopy and transmission electron microscopy. The messenger RNA expression of collagen Ⅰ and Ⅱ, β1 integrin, and caspase-9 were measured by real-time fluorescence quantitative polymerase chain reaction.Results In an immature group of rabbits, the acetabular index of the treated hip increased with animal growth. The cartilage on the brim of the left acetabulum was significantly thicker than that on the right side. The collagen fibrils on the surface of the cartilage became gross, and the chondrocytes in the enlargement layer underwent necrosis. In a mature group of rabbits, the left Sharp's angle increased in the rabbits with 6-week casting. The cartilage on the brim of the left acetabulum underwent fibrosis. The chondrocytes were weakly stained, and the number of lysosomes was much larger than normal. The messenger RNA expression of collagen Ⅰ and Ⅱ, β1 integrin, and caspase-9 in the cartilage differed significantly at different ages.Conclusions Increasing thickness followed by fibrosis may be the order of pathological cartilage changes in acetabular dysplasia, with changes in ultrastructure and collagen expression contributing to the process.

    Epidemiological evidence points strongly to a hazard of hip osteoarthritis from heavy manual work. Harmful exposures may be reduced by the elimination or redesign of processes and the 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 the 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.

    ➤Subtle forms of glenoid dysplasia may be more common than previously thought and likely predispose some patients to symptomatic posterior shoulder instability. Severe glenoid dysplasia is a rare condition with characteristic radiographic findings involving the posteroinferior aspect of the glenoid that often remains asymptomatic.➤Instability symptoms related to glenoid dysplasia may develop over time with increased activities or trauma. Physical therapy focusing on rotator cuff strengthening and proprioceptive control should be the initial management.➤Magnetic resonance imaging and computed tomographic arthrograms are useful for detecting subtle glenoid dysplasia by revealing the presence of an abnormally thickened or hypertrophic posterior part of the labrum, increased capsular volume, glenoid retroversion, and posteroinferior glenoid deficiency.➤Open and arthroscopic labral repair and capsulorrhaphy procedures have been described for symptomatic posterior shoulder instability. Glenoid retroversion of >10° may be a risk factor for failure following soft-tissue-only procedures for symptomatic glenoid dysplasia.➤Osseous procedures are categorized as either glenoid reorientation (osteotomy) or glenoid augmentation (bone graft), and no predictable results have been demonstrated for any surgical strategy. Glenoid osteotomies have been described for increased retroversion, with successful results, although others have noted substantial complications and poor outcomes.➤In severe glenoid dysplasia, the combination of bone deficiency and retroversion makes glenoid osteotomy extremely challenging. Bone grafts placed in a lateralized position to create a blocking effect may increase the risk of the development of arthritis, while newer techniques that place the graft in a congruent position may decrease this risk.

    Rasmussen's encephalitis is a rare syndrome characterized by intractable seizures, often associated with epilepsia partialis continua and symptoms of progressive hemispheric dysfunction. Seizures are usually the hallmark of presentation, but antiepileptic drug treatment fails in most patients and is ineffective against epilepsia partialis continua, which often requires surgical intervention. Co-occurrence of focal cortical dysplasia has only rarely been described and may have implications regarding pathophysiology and management. We describe a rare case of dual pathology of Rasmussen's encephalitis presenting as a focal cortical dysplasia (FCD) and discuss the literature on this topic. PMID:25667877

    We report a 43-year-old woman who presented with a right frontoparietotemporal ischemic stroke. She had been diagnosed with Turner's syndrome during childhood and had a history of chronic estrogen therapy. Cerebral angiography showed lesions characteristics of fibromuscular dysplasia involving the right internal carotid and right vertebral arteries. We are not aware of any previous reports describing an association between fibromuscular dysplasia and Turner's syndrome. Although chronic estrogen therapy cannot be ruled out as a cause of this patient's stroke, we suggest a possible etiologic relation between these two entities.

    Kim, Yoon Hyuk; Park, Won Man; Kim, Kyungsoo; Yoo, Won Joon; Cho, Tae Joon; Choi, In Ho

    Finite element contact analyses of dysplastic hip joints were performed based on CT and MR images as a surgical planning tool of the shelf operation. The 3-D cartilage thickness was approximated using MRI, and the joint contact force was calculated from a 3-D expansion of the Ninomiya’s method. After surgical planning, the anatomical parameters including the CE angle, the AC angle, the sharp angle and the spheric sector angle were improved to normal hips. The mechanical parameters including the maximum contact pressure, the contact area and the quality of contact pressure distribution also were improved. The present models and the results can be used as a computer simulation tool for optimal pre-operative planning of the shelf operation in hip dysplasia.

    Our aim was to compare hip arthroplasty with internal screw fixation in the repair of intertrochanteric fractures in elderly patients with osteoporosis. Of 112 included patient, 70 (81.81 ± 4.88 years) received hip arthroplasty with a prosthesis specially designed for intertrochanteric fractures, and 42 (83.46 ± 5.11 years) underwent plate-screw fixation. The hip arthroplasty group had significantly longer operation time, intraoperative blood loss, and total volume of blood transfused but had shorter time to beginning weight-bearing (5.94 ± 2.76 vs 23.68 ± 22.01 days) and higher postoperative Harris hip score (91.37 ± 4.80 vs 86.14 ± 5.46). In the arthroplasty group, there were 2 dislocations; and in the plate-screw fixation group, there were 5 internal fixation failures. Hip arthroplasty is preferable to internal fixation in elderly patients (age >80 years) with osteoporosis. PMID:21530148

    Full Text Available Fibrous dysplasia (FD is a condition in which normal bone marrow is replaced by an abnormal proliferation of new fibrous connective tissue. Female patient, white, 20 years old, attended the dental clinic reporting a slow increase in volume in the right mandible region over the last 5 years. She was examined by imaging: the panoramic X-ray revealed a lesion with the appearance of ground glass while the cone-beam computed tomography showed an extensive lesion in the region of the right hemimandible. The histopathological examination was compatible with fibrous dysplasia. Bone gammagraphy was indicated, plus an endocrinological study to eliminate polyostotic forms, which produced a negative result. Monostotic fibrous dysplasia in the right hemimandible was diagnosed. Conservative surgery was carried out and after 1 year recurrence of the tumour was observed. We may conclude that conservative surgery might not be the best choice for treatment for monostotic fibrous dysplasia in the mandible and that other options must be considered, such as radical surgery or the use of bisphosphonates. In our study, we may also conclude that it is very important to explain to the patient the possibility of recurrence of the lesion and the need for monitoring with periodic imaging studies.

    The aim of this study was to describe MR findings of osteofibrous dysplasia. MR images of 24 pathologically proven osteofibrous dysplasia cases were retrospectively analyzed for a signal intensity of the lesion, presence of intralesional fat signal, internal hypointense band, multilocular appearance, cortical expansion, intramedullary extension, cystic area, cortical breakage and extraosseous extension, abnormal signal from the adjacent bone marrow and soft tissue and patterns of contrast enhancement. All cases of osteofibrous dysplasia exhibited intermediate signal intensity on T1-weighted images. On T2-weighted images, 20 and 4 cases exhibited heterogeneously intermediate and high signal intensity, respectively. Intralesional fat was identified in 12% of the cases. Internal low-signal bands and multilocular appearance were observed in 91%. Cortical expansion was present in 58%. Intramedullary extension was present in all cases, and an entire intramedullary replacement was observed in 33%. Cortical breakage (n 3) and extraosseous mass formation (n = 1) were observed in cases with pathologic fractures only. A cystic area was observed in one case. Among 21 cases without a pathologic fracture, abnormal signal intensity in the surrounding bone marrow and adjacent soft tissue was observed in 43% and 48%, respectively. All cases exhibited diffuse contrast enhancement. Osteofibrous dysplasia exhibited diverse imaging features ranging from lesions confined to the cortex to more aggressive lesions with complete intramedullary involvement or perilesional marrow edema.

    Geleophysic dysplasia (GD) is a rare genetic disorder characterized by acromelic dysplasia. Geleophysic dysplasia type 1 (MIM 231050) is autosomal recessive and is caused by homozygous or compound heterozygous mutation in the ADAMTSL2 (a disintegrin and metalloproteinase with thrombosponding repeats-like 2) gene. Geleophysic dysplasia type 2 (MIM 614185) is autosomal dominant and is caused by heterozygous mutation in the fibrillin 1 (FBN1) gene. Here, we present the clinical and histopathologic findings in a child with GD with newly identified ADAMTSL2 mutations. The 1st mutation was probably a pathogenic one, c.[1934G>A] p.[Arg645His], located in exon 13; the 2nd, in intron 8, was probably changing a splice site. While the light and electron microscopic findings were similar to those previously described, hydrocephalus due to aqueductal stenosis might be a new associated finding in these patients. This child with these 2 novel mutations also had an aggressive clinical course with early-onset progressive cardiac valvular disease. PMID:24251637

    Full Text Available Canine elbow dysplasia (CED is a complex of diseases resulting in osteoarthritis (OA. CED includes ununited anconeal process (UAP, fragmented medial coronoid process (FMCP, osteochondritis (OC of the medial humeral condyle, and elbow incongruity. A patient with OC of the medial humeral condyle and FMCP was treated by arthroscopy for micro-fractures of subchondral bone and removal, respectively, and received intra-articular doses of autologous platelet concentratres (APC. The patient was evaluated by clinical examination, synovial fluid cytology, radiographic assessment and platform force evaluation, before surgery and at 30, 60 and 90th postoperative days. The patient reached full clinical recovery at 60th postoperative day with improvement in the synovial fluid cytology and the kinematic findings. However, radiological evaluation showed a progressive development of OA. Results from this report may suggest the potential-use of APC as a symptomatic modifying therapy in the treatment of OA secondary to elbow dysplasia in the dog.

    Full Text Available This paper aimed to present the first results of an explorative screening program currently running in Italy and focussing  on the prevalence of a specific orthopaedic disorder, elbow dysplasia (ED, in some breeds of dogs commonly reared in  Italy. Data consisted of radiographic findings taken on 1370 dogs (758 females and 612 males of 6 breeds (Bernese  Mountain dog, Cane Corso, German Shepherd , Golden Retriever, Labrador Retriever and Rottweiler screened at an age  of 20.6 ± 11.6 months. Radiographs were graded for both ED and hip dysplasia (HD according to a four- (0 to 3 or a  five-grade (A to E linear system, respectively. Logistic regression analysis was used for studying the relationships  between breed, sex, age of dogs at screening and HD diagnosis with the outcome of the diagnosis for ED. Prevalence of  ED (ED score ≥ 1 for the pool of breeds involved was 25%, and Labrador Retriever (17% and Rottweiler (40% showed,  respectively, the lowest and the highest prevalence of ED among breeds in the study. Prevalence of HD (grades C or high-  er approached 15%. When compared to other breeds, Rottweiler and Bernese Mountain dogs showed significantly high-  er risk to be affected by ED (odds ratio 3.2 and 3.0, respectively. Conversely, sex did not significantly affect the onset  of ED. When compared to the youngest group of dogs at screening (average: 14 months, the oldest group of screened  dogs (average: 40 months exhibited a significantly higher risk of being diagnosed as affected by ED (odds ratio: 1.9.  A negative status of hip joints appeared positively associated with a negative status of elbow joints, and dogs diagnosed  as affected by HD had a 40% increased risk of being diagnosed as affected by ED. In conclusion, results from this study  demonstrated that ED has a noticeable prevalence in some Italian dog populations, particularly in heavy breeds.  Screening of dogs for ED appeared feasible and should be performed

  14. A Huge Capital Drop with Compression of Femoral Vessels Associated with Hip Osteoarthritis

    Directory of Open Access Journals (Sweden)

    Tomoya Takasago

    2015-01-01

    Full Text Available A capital drop is a type of osteophyte at the inferomedial portion of the femoral head commonly observed in hip osteoarthritis (OA, secondary to developmental dysplasia. Capital drop itself is typically asymptomatic; however, symptoms can appear secondary to impinge against the acetabulum or to irritation of the surrounding tissues, such as nerves, vessels, and tendons. We present here a case of unilateral leg edema in a patient with hip OA, caused by a huge bone mass occurring at the inferomedial portion of the femoral head that compressed the femoral vessels. We diagnosed this bone mass as a capital drop secondary to hip OA after confirming that the mass occurred at least after the age of 63 years based on a previous X-ray. We performed early resection and total hip arthroplasty since the patient’s hip pain was due to both advanced hip OA and compression of the femoral vessels; moreover, we aimed to prevent venous thrombosis secondary to vascular compression considering the advanced age and the potent risk of thrombosis in the patient. A large capital drop should be considered as a cause of vascular compression in cases of unilateral leg edema in OA patients.

    Zimny, N J

    1998-01-01

    This case report describes the clinical reasoning used to manage chronic left hip pain in a 21-year-old woman who was recreationally active. The patient had a history of possible congenital hip dysplasia (CHD) and known recurrent lateral (external) patellar subluxations on the left side. She complained of experiencing hip pain when walking, sitting, playing soccer, and doing "step aerobics." Hip range of motion (ROM), muscle force, and joint stability problems were assessed. Abnormal movement patterns were observed during gait and step aerobics. Intervention was based on the working hypothesis that periarticular stiffness and muscle weakness from earlier trauma were superimposed on joint instability from CHD. Following intervention, the patient's hip ROM and muscle force improved concurrently with reduction of hip pain, increased ability to participate in recreational activities, and improvement in the movement pattern during step aerobics. An eclectic approach to analysis of the problem was used, combining data unique to the patient with knowledge of CHD and concepts proposed by Cyriax, Maitland, Sahrmann, and others. The clinical reasoning used to establish a basis for treatment and its limitations are discussed.

    CT scan is widely used in orthopedic examinations. By three-dimentional display of the form of bone and joint, the change of form can be identified and the lesion can be located. CT figures were stereographically processed using a personal computer to display the images of the hip joints. The outlines of the bone seen on the CT film were directly traced with a digitizer, then the A/D converted coordinate data were obtained. The data for each slice were input to the personal computer. After conversion to normal coordinate and magnification, the data were filed on the floppy disc. These data were regained from the disk and made affin transformation to display the stereographic images of the hip joints. In a case of solitary bone cyst of the coxal bone, this method helped us to decide the appropriated surgical approach. For the congenital dysplasia of the hip, acetabular coverage was examined three-dimensionally and postoperative changes were assessed in the cases of shelf operation and intertrochanteric extension osteotomy. In the cases of aseptic necrosis of the femoral head, location and size of the necrotic area were clearly visualized and the appropriate surgical procedure could be decided. Moreover, it was useful to decide the degree of rotation of the femoral head in rotational osteotomy. (author) 61 refs.

    Full Text Available Dysplasia is a morphological term that ethymologically means ‘malformation’. For the definition of inflammatory bowel disease-related dysplasia, the nature and origin of the malformation are stressed and the lesion is defined as an epithelial malformation that is unequivocally neoplastic but noninvasive. The use of a precise definition is necessary because of the clinical consequences related to the finding of dysplasia in IBD. The microscopic diagnosis of dysplasia, however, remains difficult. Clinically, it is important to make a proper differential diagnosis between polypoid IBD-related dysplasia and sporadic adenoma occurring in IBD, and between therapy-related ‘pseudodysplasia’ and genuine dysplasia. When dysplasia is diagnosed, a second opinion may be indicated because of the clinical consequences. Additional techniques to search for genetic defects associated with carcinogenesis can help to support the diagnosis. They can identify changes in DNA content and molecular changes resulting from defects of genes controlling cell proliferation and death or tissue structure. These changes can, however, be absent, appear early or late in the transition from normality toward dysplasia and cancer, or appear during repair. Positive findings indicate an increased cancer risk, but the magnitude of the risk remains to be defined. A positive diagnosis of genuine dysplasia necessitates clinical action – either follow-up of the patient or treatment. In practice, treatment means surgery because dysplasia can be a precursor and/or a marker of malignancy, except for sporadic adenomas, which can be removed locally.
