    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.

    Background Wrist arthroscopy plays a role in both the diagnosis and the treatment of wrist pathology. It has evolved in the last three decades. Questions The present status of wrist arthroscopy was investigated by answering the following questions: -What is its current position in the treatment wrist pathologies according to the literature? -What is its current position according to hand surgeons? Methods Analysis of the number of publications on wrist arthroscopy was performed and compared with the number of publications on other arthroscopy topics to assess the current position of wrist arthroscopy. The members of the EWAS (European Wrist Arthroscopy Society) and the members of eight national hand surgery societies were questioned on wrist arthroscopy in daily practice. Results From 1975 till now, 925 papers on wrist arthroscopy were found. The publications on wrist arthroscopy increased from an average of 8/year (1986) to 26/year (2012). More than half (56.9%) of the respondents of the EWAS perform fewer than 5 wrist arthroscopies per month, and only 7 (10.8%) indicate the performance of more than 10 wrist arthroscopies per month. Seventy-four percent of the orthopedic hand surgeons perform wrist arthroscopy (in 48.5% for therapeutic indications) against 36.8% of plastic surgery hand surgeons (in 23.1% for therapeutic indications). Conclusion Wrist arthroscopy has taken up a place in the armamentarium of the hand surgeon. The place of wrist arthroscopy in daily practice is related to the background of the hand surgeon.

    Since its introduction more than three decades ago, wrist arthroscopy has continually evolved. The procedure has a wide list of indications, including diagnostic and management applications. The scope of practice for the wrist arthroscopic surgeon includes management of triangulofibrocartilage complex pathology, evaluation and management of carpal instability, assistance in fracture reduction of the radius and scaphoid, treatment of trapeziometacarpal synovitis and arthritis, distal ulnar and carpal bone excisions, and salvage procedures. In addition, innovations such as new portals and smaller arthroscopes have expanded the applications of wrist arthroscopy. PMID:23118138

    Hip arthroscopy is a fast-growing and evolving field. Like knee and shoulder arthroscopy, hip arthroscopy began as a diagnostic procedure and then progressed to biopsy and resection of abnormalities. Subsequently, it has evolved to repair of various tissues and treatment of underlying causes. As the understanding of the hip joint and its associated pathophysiology grows, indications will continue to expand for this diagnostic and therapeutic modality. This article outlines the historic developments of hip arthroscopy, including advancements in instrumentation and techniques from the days of the first hip arthroscopies to the present day.

    The purpose of this article is to review the recent literature on arthroscopic treatment of distal radius fractures (DRFs), triangular fibrocartilage complex injuries, intercarpal ligament injuries, and ganglion cysts, including the use of electrothermal devices. A major advantage of arthroscopy in the treatment of DRFs is the accurate assessment of the status of the articular surfaces and the detection of concomitant injuries. Nonrandomized studies of arthroscopically assisted reduction of DRFs show satisfactory results, but there is only 1 prospective randomized study showing the benefits of arthroscopy compared with open reduction-internal fixation. Wrist arthroscopy plays an important role as part of the treatment for DRFs; however, the treatment for each practitioner and each patient needs to be individualized. Wrist arthroscopy is the gold standard in the diagnosis and treatment of triangular fibrocartilage complex injuries. Type 1A injuries may be successfully treated with debridement, whereas the repair of type 1B, 1C, and 1D injuries gives satisfactory results. For type 2 injuries, the arthroscopic wafer procedure is equally effective as ulnar shortening osteotomy but is associated with fewer complications in the ulnar positive wrist. With interosseous ligament injuries, arthroscopic visualization provides critical diagnostic value. Debridement and pinning in the acute setting of complete ligament tears are promising and proven. In the chronic patient, arthroscopy can guide reconstructive options based on cartilage integrity. The preliminary results of wrist arthroscopy using electrothermal devices are encouraging; however, complications have been reported, and therefore, their use is controversial. In dorsal wrist ganglia, arthroscopy has shown excellent results, a lower rate of recurrence, and no incidence of scapholunate interosseous ligament instability compared with open ganglionectomy. Arthroscopy in the treatment of volar wrist ganglia has yielded

    Wrist arthroscopy is a commonly used procedure that has undergone many modifications and improvements since it was first described. The advent of new portals (both dorsal and volar) means that the wrist joint can be viewed from virtually any perspective ("box concept"). Indications for wrist arthroscopy have continued to expand and include diagnostic and reparative procedures and, more recently, reconstructive, soft-tissue, and bony procedures. Arthroscopic grading of Kienböck's disease better describes articular damage compared with plain radiographs and can help guide surgical treatment options. Triangular fibrocartilage complex injury diagnosis, classification, and treatment can be performed arthroscopically, including distal ulna resection (wafer procedure). Assessment of fracture reduction of the distal radius and scaphoid is superior to that obtained with fluoroscopy, with the advantage of being able to look for associated soft-tissue and chondral injuries. Arthroscopic assessment of intercarpal ligament injuries and instability is now considered the gold standard by many authors. Arthroscopy can also aid us in the management of post-traumatic capsular contraction, resection of ganglia, and the relatively rare isolated ulna styloid impaction. Complications of wrist arthroscopy are relatively uncommon. With the ever-expanding list of indications and procedures that can be performed with this technique, it exists as an essential diagnostic and therapeutic tool for the orthopaedic surgeon.

    2012-09-01

    It has become clear that the stability of the scapholunate joint does not depend wholly on the scapholunate interosseous ligament, but rather on both primary and secondary stabilizers, which form a scapholunate ligament complex. Each case of scapholunate instability is unique and should be treated with tissue-specific repairs, which may partly explain why one procedure cannot successfully restore joint stability in every case. Wrist arthroscopy has a pivotal role in both the assessment and treatment of the scapholunate ligament complex derangements. Tears of the foveal attachment of the triangular fibrocartilaginous complex can be an underdiagnosed cause of distal radioulnar joint instability, because the foveal fibers cannot be visualized using the standard radiocarpal arthroscopy portals. Distal radioulnar joint arthroscopy allows for direct visualization and assessment of these fibers, which in turn has spawned a number of open and arthroscopic repair methods. Wrist arthroscopy has gained wider acceptance as a method to fine-tune articular reduction during open and percutaneous fixation of distal radius fractures, and simplifies intra-articular osteotomies for malunion. It can facilitate percutaneous bone grafting of scaphoid nonunions and has a role in the diagnosis and treatment of associated soft tissue lesions. These and other recent developments will be discussed in the following article. PMID:22916867

  15. Hip arthroscopy. The supine position.

    2001-10-01

    Hip arthroscopy is an effective technique. It can be performed successfully either supine or in the lateral position, but there appear to be modest advantages of the supine approach. Arthroscopy offers a less invasive alternative to arthrotomy for traditionally recognized forms of hip pathology, such as loose bodies or impinging osteophytes. Arthroscopy also offers a method of treatment for many conditions (including labral tears, acute articular injuries, and damage to the ligamentum teres) that previously went unrecognized and untreated. In the past, these patients were simply resigned to living within the constraints of their symptoms. Several dictums about hip arthroscopy must be acknowledged. First, the key to a successful outcome lies in proper patient selection. A technically well-executed procedure will fail when performed for the wrong reason, or when the outcome fails to meet the patient's expectations. Second, the patient must be properly positioned for the procedure to go well. Poor positioning will assure a difficult procedure. Third, simply gaining access to the hip joint is not an outstanding technical accomplishment. The paramount issue is accessing the joint in as atraumatic a fashion as possible. Due to its constrained architecture and dense soft tissue envelope, the potential for inadvertent iatrogenic scope trauma is significant and, perhaps unavoidable to some extent. Therefore, every reasonable step should be taken to keep this concern to a minimum. Perform the procedure as carefully as possible and be certain that it is being performed for the right reason. After accessing the joint, the techniques of operative arthroscopy for the hip employ existing strategies established in other joints. Because of the restraints imposed by the hip, however, technical deficiencies may be more apparent. PMID:11675882

    With the development of better and smaller equipment, arthroscopy of the wrist offers the same benefits achievable with arthroscopy of the knee, shoulder, or elbow - not only diagnostic information but also a therapeutic option. Standardized techniques of performing wrist arthroscopy have been developed to evaluate the treat various wrist disorders, such as lesions of the triangular fibrocartilage complex, intra-articular distal radius fractures, and scaphoid fractures. Arthroscopy is now performed in the treatment of dorsal-wrist ganglion cysts and interosseous ligament disruptions, as well as for bone incisions, such as radial styloidectomy, distal ulnar excision (wafer procedure), and proximal-row carpectomy. Compared with other techniques, arthroscopic procedures, such as repair of the triangular fibrocartilage complex, demonstrate better results and improved localization of the injury with a low complication rate. In addition, arthroscopic procedures involve lesssurgical dissection, less postoperative pain, a shorter recovery time, and an earlier return to work for the patient. PMID:11421577

    Fluid extravasation is possibly the most common complication of shoulder arthroscopy. Shoulder arthroscopy can lead to major increases in the compartment pressure of adjacent muscles and this phenomenon is significant when an infusion pump is used. This article describes a case of pectoral swelling due to fluid extravasation after shoulder arthroscopy. A 24-year-old male underwent an arthroscopic Bankart repair for recurrent shoulder dislocation. The surgery was performed in the beach chair position and lasted two hours. At the end of the procedure, the patient was found to have left pectoral swelling. A chest radiography showed no abnormality. Pectoral swelling due to fluid extravasation after shoulder arthroscopy has not previously been documented. PMID:26889473

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

    Distal radius fractures are the most common fractures in humans and early surgical intervention with modern plating systems is becoming increasingly more established to avoid secondary dislocation. Even fractures with slight dislocations are adequately stabilized and the affinity for surgical intervention and plating procedures is applied to secure these simple fractures. In this aspect the surgical indications are significantly dependent on X-ray examination results. Further diagnostics with respect to ligamentous and soft tissue injury are the exception although the impact energy which creates osseus fractures is sufficient by far to destroy functional soft tissue, cartilage and ligaments. The ongoing development of wrist arthroscopy enables new possibilities especially concerning concomitant articular involvement of distal radius fractures. Arthroscopy-assisted reduction and stabilization as well as minimally invasive soft tissue repair and loose body removal seem to be adequate methods to improve the surgical treatment of distal radius fractures.

    Femoroacetabular impingement may be particularly disabling to the high-demand athlete, especially those with significant cutting and pivoting requirements. If nonoperative treatment fails to adequately alleviate symptoms or sufficiently restore function in the athlete, hip arthroscopy can lead to improved pain, improved range of motion, and high rates of return to play with proper postoperative rehabilitation. The rate of return to previous level of competition is also high with accurate diagnosis and well-executed correction of deformity. A clear understanding of the etiology, diagnosis, management, and outcomes is essential for clinicians to optimally help patients to return to play. PMID:27543404

In 1931, Burman reported an experimental study on the arthroscopic exploration of cadaveric joints, but he believed that the ankle joint was unsuitable for such techniques because it was too narrow to pass through the posterior puncture.2Unexpectedly, several years later Takagi described a routine method for arthroscopic examination of the ankle.

    Full Text Available Pulmonary embolism (PE following shoulder arthroscopy is a rare complication. We present a unique case report of a 43-year-old right-hand dominant female who developed a PE 41 days postoperatively with no associated upper or lower extremity DVT. The patient had minimal preoperative and intraoperative risk factors. Additionally, she had no thromboembolic symptoms postoperatively until 41 days following surgery when she developed sudden right-hand swelling, labored breathing, and abdominal pain. A stat pulmonary computed tomography (CT angiogram of the chest revealed an acute PE in the right lower lobe, and subsequent extremity ultrasounds showed no upper or lower extremity deep vein thrombosis. After a thorough review of the literature, we present the first documented isolated PE following shoulder arthroscopy. Although rare, sudden development of an isolated PE is possible, and symptoms such as sudden hand swelling, trouble breathing, and systemic symptoms should be evaluated aggressively with a pulmonary CT angiogram given the fact that an extremity ultrasound may be negative for deep vein thrombosis.

  11. Valid MR imaging predictors of prior knee arthroscopy

    International Nuclear Information System (INIS)

    To determine whether fibrosis of the medial patellar reticulum (MPR), lateral patellar reticulum (LPR), deep medial aspect of Hoffa's fat pad (MDH), or deep lateral aspect of Hoffa's fat pad (LDH) is a valid predictor of prior knee arthroscopy. Institutional review board approval and waiver of informed consent were obtained for this HIPPA-compliant study. Initially, fibrosis of the MPR, LPR, MDH, or LDH in MR imaging studies of 50 patients with prior knee arthroscopy and 100 patients without was recorded. Subsequently, two additional radiologists, blinded to clinical data, retrospectively and independently recorded the presence of fibrosis of the MPR in 50 patients with prior knee arthroscopy and 50 without. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for detecting the presence of fibrosis in the MPR were calculated. κ statistics were used to analyze inter-observer agreement. Fibrosis of each of the regions examined during the first portion of the study showed a significant association with prior knee arthroscopy (p < 0.005 for each). A patient with fibrosis of the MPR, LDH, or LPR was 45.5, 9, or 3.7 times more likely, respectively, to have had a prior knee arthroscopy. Logistic regression analysis indicated that fibrosis of the MPR supplanted the diagnostic utility of identifying fibrosis of the LPR, LDH, or MDH, or combinations of these (p ≥ 0.09 for all combinations). In the second portion of the study, fibrosis of the MPR demonstrated a mean sensitivity of 82%, specificity of 72%, PPV of 75%, NPV of 81%, and accuracy of 77% for predicting prior knee arthroscopy. Analysis of MR images can be used to determine if a patient has had prior knee arthroscopy by identifying fibrosis of the MPR, LPR, MDH, or LDH. Fibrosis of the MPR was the strongest predictor of prior knee arthroscopy. (orig.)

    2006-01-01

    The athlete's elbow has been described as one of the last frontiers in orthopaedic sports medicine. It has been considered separately from other athletic injuries because of the unique constellation of pathology that results from repetitive overhead throwing. Tremendous gains in understanding the complex interplay between the dynamic and static stabilizers of the athlete's elbow have occurred over the past decade. The desire to treat these injuries in a minimally invasive manner has driven the development of techniques and instrumentation for elbow arthroscopy, a successful and essential technique in the treatment of the thrower's elbow. Medial collateral ligament injuries, ulnar neuritis, valgus extension overload with osteophyte formation and posteromedial impingement, flexor pronator strain, medial epicondyle pathology, and osteochondritis dissecans of the capitellum have all been described as consequences of the overhead throwing motion. In addition, loose body formation, bony spur formation, and capsular contracture can each be present in conjunction with these conditions or as isolated entities. Not all pathology in the thrower's elbow is amenable to arthroscopic treatment; however, the clinician must be familiar with all of these conditions to form a comprehensive differential diagnosis for an athlete with elbow pain. The surgeon treating the athlete's elbow should be comfortable with both open and arthroscopic treatments. An understanding of the anatomy and biomechanics of the thrower's elbow is essential for good patient care. The preoperative evaluation should focus on a thorough history and physical examination, as well as specific diagnostic imaging modalities. PMID:16958443

    The traditional method of surgical training has followed the 'observe, practice, and teach' model, which is useful for open surgery, but is insufficient for minimally invasive surgery. This study presents the validation of a new simulator designed for TMJ arthroscopy training. A group of 10 senior maxillofacial surgeons performed an arthroscopy procedure using the simulator. They then completed a questionnaire analyzing the realism of the simulator, its utility, and the educational quality of the audiovisual software. The mean age of the 10 surgeons was 42.6 years, and they had performed a mean 151 arthroscopies. With regard to the realism of the simulator, 80% reported that it was of an appropriate size and design and 70% referred to the very realistic positions and relationships between the internal structures. Regarding its educational potential, 80% reported the simulator to be very useful for acquiring the basic skills and to acquire the sensation of depth during access to the TMJ. Finally, 90% reported the prototype to be very useful for TMJ arthroscopy training. These preliminary results showed a high degree of approval. The general opinion of the group of experts was that the experience was rewarding and inspiring, and that the prototype has the educational potential for the achievement of basic TMJ arthroscopy skills.

  14. MR imaging before arthroscopy in knee joint disorders?

    International Nuclear Information System (INIS)

    Purpose: To review the current literature examining the relative merits of arthroscopy and MR imaging of the knee. Material and Methods: All papers comparing MR imaging with arthroscopy published within the last 10 years according to Medline were collected and read. Results: Technology has improved considerably during recent years allowing detailed non-invasive visualization of the knee. In particular, the development of cheaper whole-body and dedicated low-field MR units has opened up for non-invasive inspection of the knee at reasonable cost. Meniscal tears can be detected with accuracy rates of around 90% and rupture of the anterior cruciate ligament with accuracy rates of around 93% compared to arthroscopy. However, arthroscopy is not the ideal gold standard, since it has weak points, e.g. peripheral meniscal tears or osteochondritis without apparent damage to the cartilage. Conclusion: Based on the overwhelming literature it seems safe to conclude that MR examinations of the knee should be performed before arthroscopy is undertaken. (orig.)

    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.

    Intra-articular ganglion cysts of the knee joint are rare and most frequently are an incidental finding on MRI and arthroscopy. Most of the previous studies have reported a single ganglion cyst in the knee. There have been previous reports of more than one cyst in the same knee but not in the same structure within the knee. We are reporting a case of dual ACL (anterior cruciate ligament) ganglion cysts one of which was missed on radiological examination but later detected during arthroscopy. ...

    1984-02-01

    Knee arthroscopy in a patient with undiagnosed chronic monoarticular arthritis revealed dark pigmentation of the snyovium; synovial biopsy revealed histologic and ultrastructural features characteristic of ochronosis. Synovial fluid (SF) was non-inflammatory, without pigmented shards of cartilage; calcium pyrophosphate dihydrate crystals were absent in both the SF and biopsy specimen. Homogentisic acid was detectable in the urine by thin layer chromatography, and asymptomatic spondylosis with intervertebral disc calcification was found. The negative family history, lack of mucocutaneous pigmentation and failure of the urine to spontaneously darken obscured the diagnosis, which was easily made by arthroscopy. PMID:6699824

    Full Text Available Growing awareness of femoroacetabular impingement (FAI and recent innovations in management has resulted in hip arthroscopy becoming one of the fastest-growing orthopaedic subspecialties. The purpose of this study was to identify the 50 most cited articles related to the topic of FAI and hip arthroscopy and to analyze their characteristics.The overall number of citations within these articles ranged from 99 to 820. Citation density ranged from 4.41 to 74.55. Seven countries produced these articles with the majority attributed to the United States (n=26 and Switzerland (n=18. Clinical studies made up more than half of the top articles (n=27. The JBJS level of evidence most commonly encountered was level IV (n=24 while the remaining articles were level III (n=3. No randomized controlled trials or non-randomized controlled trials were encountered in this search. The level of evidence was not significantly correlated with the overall number of citations, publication year, or citation density. The current top 50 list provides orthopaedic surgeons interested in hip arthroscopy with anup-to-date core list of the most cited articles in the scientific literature and represents a foundation to use to develop their knowledge regarding hip arthroscopy and FAI.

  2. Only MR can safely exclude patients from arthroscopy

    International Nuclear Information System (INIS)

    The aim of this study was to determine in patients with subacute knee complaints and normal standardized physical examination the fraction of magnetic resonance imaging (MRI) studies showing arthroscopically treatable intra-articular pathology. There were 290 consecutive patients (between 16 and 45 years) with at least 4 weeks of knee complaints and low clinical suspicion of intra-articular pathology based on physical exam. Two hundred seventy-four patients were included. Sixteen patients with prior knee surgery, rheumatic arthritis, or severe osteoarthritis were excluded. MRI was used to assign patients to group 1 (treatable abnormalities) or group 2 (normal or no treatable findings), depending on whether MR demonstrated treatable pathology. Arthroscopy was performed in group 1 patients. If symptoms persisted for 3 months in group 2 patients, cross over to arthroscopy was allowed. MR showed treatable pathology in 73 patients (26.6%). Arthroscopy was performed in 64 patients of 73 patients (group 1). In 52 patients (81.3%, 95% confidence interval (CI) 71.4-91.1%), arthroscopy was therapeutic. Of the 13 arthroscopies (6.5%) in group 2, four were therapeutic (30.8%, 95% CI 1.7-59.8). The highest fraction of MR studies showing treatable pathology was found in males, aged over 30 years, with a history of effusion (54.5%, six of 11 patients). Authors believe that the negative predictive value of clinical assessment in patients with subacute knee complaints is too low to exclude these patients from MR. MR should at least be considered in male patients aged 30 years and over with a history of effusion. (orig.)

    2016-08-01

    Hip arthroscopy is a fast growing orthopedic field of expertise. As in any field of surgery adequate postoperative pain management regimes are of utmost importance. The purpose of this review is to provide an overview of current knowledge on anesthetic options for perioperative pain management for hip arthroscopy. We searched the Pubmed/Medline and Embase database for literature and included 10 studies for our analysis. Because of the variety of pain scales and different ways of measured pain no meta-analysis could be performed and a descriptive review is performed. There are several types of pain regimens that can mostly be divided in two groups: local anesthetics and nerve blocks. Included studies show a rather large variation in reported visual analogue scale scores, post anesthesia care unit admission time and opioid usage. There are several anesthetic options available for hip arthroscopy. Different studies use different dosages, anesthetic regimens and different protocols; this partly explains the differences between studies with similar techniques. Peripheral nerve blocks seems promising but regarding current literature no clear recommendation can be made about what the best perioperative pain management option is, an overview of all reported techniques is given.

    Full Text Available Background and Aims: Shoulder arthroscopy requires fluid irrigation, which causes soft-tissue oedema around chest, neck, and arm intraoperatively, leading to postoperative airway complications. We decided to study the incidence of increase in the neck circumference in shoulder arthroscopy and its effects on the airway. Methods: We studied 32 cases of shoulder arthroscopies over a period of 1-year, performed under general anaesthesia with interscalene block. The neck circumference of patients before and after the procedure was measured along with other parameters. The endotracheal tube cuff was deflated at the end of surgery to determine air leak around the tube. The negative leak test suggested airway oedema. Results: Thirty out of 32 patients showed positive air leak test. The average change in neck circumference was 1.17 ± 1.16 cm and all could be extubated uneventfully. Two showed negative leak test with an increase in neck circumference by 4.5 and 6.4 cm and were not extubated. Multiple regression analysis for risk factors showed intraoperative hypertension as a single predictor for an increase in neck circumference. Conclusion: Change in the neck circumference beyond 4 cm may suggest airway compromise and below 4 cm, airway compromise is unlikely even in the presence of extensive soft-tissue oedema around the shoulder, upper arm and chest.

    Ankle arthroscopy is an important diagnostic and therapeutic technique in the management of ankle disorders. Nowadays ankle arthroscopy provides good to excellent results (up to 90%) in the treatment of certain intra-articular disorders. Due to the superficial location of ankle joint and the abundance of overlying neurovascular structures, complications reported in ankle arthroscopy are greater than those reported in other joints. We present the first reported case of a complete division of the posterior tibial nerve during an anterior ankle arthroscopy combined with an additional posterolateral portal. This was due to a poorly controlled use of the arthroscopic instruments. PMID:27197613

    2016-01-01

    Background and purpose Several randomized controlled trials have not shown any added benefit of arthroscopy over placebo surgery or physiotherapy in middle-aged patients with knee symptoms without trauma. We studied the characteristics of the knee arthroscopies performed in southern Sweden. Patients and methods From the orthopedic surgical records from 2007–2009 in the Skåne region of Sweden (with a population of 1.2 million), we retrieved ICD-10 diagnostic codes and selected all 4,096 arthroscopies that were diagnosed peroperatively with code M23.2 (derangement of meniscus due to old tear or injury) or code M17 (knee osteoarthritis). We extracted information on cartilage and meniscus status at arthroscopy, and we also randomly sampled 502 of these patients from the regional archive of radiology and analyzed the preoperative prevalence of radiographic or magnetic resonance imaging (MRI)-defined osteoarthritis. Results 2,165 (53%) of the 4,096 arthroscopies had the diagnostic code M23.2 or M17. In this subgroup, 1,375 cases (64%) had typical findings consistent with degenerative meniscal tear (i.e. that correspond to a degenerative meniscal tear in at least a third of all arthroscopies). Of the randomly sampled patients, the preoperative prevalence of radiological knee osteoarthritis was 46%. Interpretation There is a discrepancy between evidence-based medicine treatment guidelines and clinical practice regarding the amount of knee arthroscopies performed in patients with symptoms of degenerative knee disease.

  18. Elbow arthroscopy: setup, portal placement, and simple procedures.

    Science.gov (United States)

    Ahmad, Christopher S; Vitale, Mark A

    2011-01-01

    Elbow arthroscopy has become an accepted treatment for numerous elbow conditions, including loose bodies, lateral epicondylitis, contractures, painful osteophytes, synovitis, osteochondritis dissecans, synovial plica, and osteoarthritis. It is absolutely necessary that the treating surgeon have complete knowledge of elbow anatomy. Three options exist for patient positioning: supine, prone, and lateral decubitus. Standard arthroscopic probes, grasping forceps, punches, and motorized shavers and burrs are used in the procedure. Retractors are essential for visualizing, exposing, and protecting nerves. Specially designed capsular biters can be used to develop a plane between the capsule and the surrounding soft tissues to facilitate capsulotomy and capsulectomy. Among elbow arthroscopists, the sequence of portal placement varies; however, there is little variation in the exact location of portal placement because of neurovascular constraints. Loose body removal and extensor carpi radialis brevis release for lateral epicondylitis are common procedures suitable for the beginning arthroscopist. For beginning and advanced procedures, the surgeon's skill and competence must be at a level consistent with the procedure to avoid complications. PMID:21553771

    2001-01-01

    Objective: To evaluate the therapeutic effects of retrograde interlocking intramedullary nailing under arthroscopy on supracondylar femoral fractures.   Methods: From June 1999 to December 2000, 17 patients with supracondylar femoral fracture were treated with arthroscopically assisted implantation of retrograde interlocking intramedullary nail and close reduction.   Results: More than 6-month follow-up study after operation in 11 patients revealed that the average healing time was 3 months. Average range of the knee motion for all the patients was more than 90 degrees. There was no implant breakage and infection.   Conclusions: This new method, combining the advantage of arthroscope and retrograde interlocking intramedullary nail, can provide a stable and reliable fixation, and meanwhile is less invasive to the soft tissue and knee, less operative time and blood loss, minimal disruption of the blood supply in fracture site. It is conducive to the fracture healing and the functional recovery of the knee joint and worthwhile to be recommended.

    2002-11-01

    Purpose: A prospective study was undertaken to determine the accuracy of ultrasound compared with arthroscopy in the evaluation of the symptomatic supraspinatus tendon, and to identify whether ultrasound diagnosis was helpful in pre-operative planning. Methods: A total of 276 consecutive patients with shoulder impingement symptoms underwent ultrasound examination of the supraspinatus tendon. Of these patients, 41 proceeded to open or arthroscopic surgical procedure on clinical grounds, and in this group direct comparison with ultrasound findings was made. Results: There was full correlation between ultrasound and arthroscopy in the diagnosis of a normal supraspinatus tendon, full-thickness tear, tendinopathy and tendon rupture. There was some discrepancy between the two techniques. Two patients with partial thickness tear on ultrasound had a full thickness tear at arthroscopy. Ultrasound was able to identify intra-substance partial thickness tears in three patients with supraspinatus tendon said to be normal at arthroscopy. Ultrasound helped plan the surgical approach and operative time needed in cases of supraspinatus tendon rupture and full thickness tear. Conclusion: In this study ultrasound was effective in the evaluation of the symptomatic supraspinatus tendon, and was also able to diagnose intra-tendinous lesions not visible at arthroscopy.

  2. Diagnostic Efficiency of MR Imaging of the Knee. Relationship to time Interval between MR and Arthroscopy

    International Nuclear Information System (INIS)

    To evaluate the efficiency of magnetic resonance (MR) in the diagnosis of knee lesions and how the results are influenced by the time interval between MR and arthroscopy. 248 knees studied by MR were retrospectively analyzed, as well as those which also underwent arthroscopy. Arthroscopy was considered to be the gold standard, MR diagnostic capacity was evaluated for both meniscal and cruciate ligament lesions. Sensitivity, specificity and Kappa index were calculated for the set of all knees included in the study (248), for those in which the time between MR and arthroscopy was less than or equal to three months (134) and for those in which the time between both procedures was less than or equal to one month. Sensitivity, specificity and Kappa index of the MR had global values of 96.5%, 70% and 71%, respectively. When the interval between MR and arthroscopy was less than or equal to three months, sensitivity, specificity and Kappa index were 95.5%, 75% and 72%, respectively. When it was less than or equal to one month, sensitivity was 100%, specificity was 87.5% and Kappa index was 91%. MR is an excellent tool for the diagnosis of knee lesions. Higher MR values of sensitivity, specificity and Kappa index are obtained when the time interval between both procedures is kept to a minimum. (Author) 11 refs

  3. Fibrous scar in the infrapatellar fat pad after arthroscopy. MR imaging

    International Nuclear Information System (INIS)

    We describe the MR appearance of fibrous scars in the infrapatellar fat pad after arthroscopy. The subjects were 96 patients who underwent arthroscope-assisted anterior cruciate ligament (ACL) reconstruction and were examined by oblique sagittal MR imaging at different follow-up intervals. Two observers evaluated the characteristics of the fibrous scars in the infrapatellar fat pad. All fibrous scars with low signal intensity were accentuated at the portal and coursed horizontally through the infrapatellar fat pad. The fibrous scar within the fat pad occurred and peaked within 6 months after arthroscopy. It then subsided gradually and had disappeared by one year later in nearly half of the patients. Identifying MR imaging characteristics of fibrous scars in the fat pad after arthroscopy may be clinically helpful to differentiate these scars from other abnormalities that involve the infrapatellar fat pad.

    Full Text Available INTRODUCTION: The anterior cruciate ligament (ACL is one of the most frequently injured ligaments in the human body. 1 The Anterior Cruciate ligament (ACL is the primary stabilizer of the knee and prevents the knee against anterior translation. 2 It is also important in counteracting rotational and valgus stress. 1 The middle third of the patellar tendon autograft for ACL reconstruction can be readily procured and firmly fixed. 3 It can tolerate the loads produced by an intensive rehabilitation programme. 3 Fixation of bone plugs using interference screws provides sufficient stability to meet the demand of a vigorous postoperative protocol. 3 It remains the gold standard for ACL reconstruction. 3 This study is to assess the functional outcome of arthroscopy assisted anterior cruciate ligament reconstruction using bone patellar tendon bone autograft. METHODS: This study was conducted in Kempegowda Institute of Medical Sciences Hospital from November 2012 to April 2014. During this period 20 cases of adult patients with ACL deficient patients were selected according to the inclusion criteria. Study aims to assess the functional outcome of arthroscopy assisted anterior cruciate ligament reconstruction using bone - patellar tendon - bone autograft in terms of range of motion, postoperative knee stability, graft site morbidity and subjective knee functions. RESULTS: Results of our study showed that arthroscopy assisted anterior cruciate ligament reconstruction with bone - patellar tendon - bone autograft could effectively improve knee stability and functions after surgery without any complication. CONCLUSION : Arthroscopy assisted anterior cruciate l igament reconstruction with bone - patellar tendon - bone autograft is an excellent treatment option for anterior cruciate ligament deficient knees. It provides a stable knee and reduces postoperative morbidity and enables early rehabilitation. The functional outcome of arthroscopy assisted anterior

    Arthroscopy of the foot and ankle is a common orthopedic procedure with low complication rates. Arterial injuries from these procedures are an even more rare subset of the complications. Hemophilia A is a genetic disorder of aberrant coagulation, which leads to increased risk of bleeding even after minor trauma. We present the second case of anterior tibial artery pseudoaneurysm formation secondary to ankle arthroscopy in a hemophiliac patient and suggest that these individuals are at higher risk for developing complications associated with arterial injury. Furthermore, potential risk factors include port placement, anatomic variation of the vessels, and nature of the arthroscopic procedure. We recommend steps to prevent complications in hemophiliac patients. PMID:27174350

  8. Synovialisation of the torn anterior cruciate ligament of the knee: comparison between magnetic resonance and arthroscopy

    International Nuclear Information System (INIS)

    The aim of this study was to assess the accuracy of MR in the diagnosis of synovialisation of the anterior cruciate ligament (ACL) compared with arthroscopy. One hundred and forty-nine patients were examined with MR imaging and arthroscopy of the knee. The MR sign used to consider a synovialised ACL consisted of hypointense fibrillar tracts, disrupted and wavily, in its expected course. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), comparison of proportions (McNemar test) and Kappa values for agreement between MR imaging and arthroscopy were calculated. Of the 133 (89.3 %) ligaments without synovialisation at arthroscopy, 130 accorded with the MR results. Of the 16 (10.7 %) synovialised ligaments, 13 accorded with the MR results. Three false-positive and three false-negative MR diagnoses were identified. The agreement between both techniques was excellent (Kappa = 0.79; p = 0.000), without differences (McNemar test; p = 1). Sensitivity was 0.81, specificity 0.98, PPV 0.98 and NPV 0.81. Magnetic resonance imaging is highly reliability for synovialisation diagnosis. The imaging sign used to diagnose synovialised ACL (hypointense comma-like tracts in its expected course) is reliable. As this reparative process can simulate an intact ligament, knowledge of this sign is important in diagnosing synovialisation of ACL tears so as not to confuse it with normal ACL. (orig.)

The functional results after arthroscopy were evaluate using Mc Cullough Score. In 78% of cases the pain disapeared significantly. There was made in all cases debridation with shaver, in 12 cases microabrasive chondroplasty and in 7 cases ligamentoplasty of the anterior talofibular ligament and/or deltoid ligament. In 76% there was, at least an associated, „hiden”, lesion, wich need also arthroscopic treatment. We have one complication (4,3% represented by a superficial chondral lesion, wich was treated by microabrasive chondroplasty. There were any neurological, vascular or other complications. The results show us that ankle arthroscopy remain a certain, mini-invazive method to diagnose and for the treatment of the ankle lesions. Arthroscopic ligamentoplasty of the ankle is still in confirmation. Arthrocopy is the main procedure for treating the impingement syndrom of the ankle and osteochondral lesion – injury that are frecventely associated with chronic ankle instability.

  13. Prospective, double-blind comparison of shoulder MR imaging, US, arthrography, and arthroscopy

    International Nuclear Information System (INIS)

    To determine the efficacy of diagnostic imaging modalities in the evaluation of shoulder pain, magnetic resonance (MR) imaging, ultrasonography (US) and arthrography were prospectively compared in a double-blind experimental protocol. Thirty consecutive patients were studied by these modalities, which received separate, blinded interpretations. The images and interpretations were sealed in an envelope and blinded from the arthroscopist for initial arthroscopy, but second-look arthroscopy, and in some cases open surgery, was performed after the envelopes were unsealed. To avoid selection bias, negative MR and/or US examinations never affected confirmation by arthrography and/or arthroscopy, so negatives and positives were equivalently tested. To date, MR imaging and US are equally sensitive in the detection of rotator cuff tears, but the combination is more sensitive. Both MR imaging and US demonstrated tears not diagnosed by means of arthrography, and MR imaging distinguished hemorrhagic muscle tears from rotator cuff tears, which arthrography and arthroscopy did not. Both MR imaging and US showed characteristic appearances of biceps tendonitis, but neither demonstrated adhesive capsulitis. The authors conclude that all three imaging modalities have a role in shoulder diagnosis

    Full Text Available Hip arthroscopy has continued to expand its horizons in treating many conditions other than femoroacetabular impingement (FAI. However, the results of hip arthroscopy are known to be poor if the degree of articular cartilage damage is significant. We wanted to assess, whether the procedure might have a role in the management of young and active patients with advanced osteoarthritis (OA and whether it should be offered as a treatment modality. 77 consecutive patients with Tönnis grade 2 and 3 osteoarthritis of the hip who had undergone hip arthroscopy were included in the study. Patients' medical notes, plain radiographs and outcome scores (modified Harris hip score (mHHS, non-arthritic hip score (NAHS preoperatively and postoperatively at six weeks, six months, one year and annually thereafter, were analysed. 77 patients consisted of 63 men and 14 women with mean follow-up of 2.8 years (2.2 to 4.2 and mean age at surgery of 43 years (19 to 64. The mean preoperative mHHS and NAHS scores were 58 (28 to 87 and 64 (27 to 93 respectively. The mean improvements in both the mHHS and NAHS scores were significant (p = 0.003 and p = 0.0001 for mHHS at one and two years, p = 0.002 and p = 0.0003 for NAHS at one and two years, respectively. There were 34 patients (44% who required a total hip replacement at mean of 18 months (6 to 48 after hip arthroscopy. We conclude that hip arthroscopy improves outcome scores in 56% of patients with severe OA of the hip (Tönnis grade 2 and 3 for at least two years after surgery. We thus consider the procedure to be a reasonable option for patients with hip OA, although success of the procedure will be less than if undertaken for certain other conditions.

  16. The comparative analysis of magnetic resonance imaging and arthroscopy of the temporomandibular joints

    International Nuclear Information System (INIS)

    The aim of the study was to correlate arthroscopic and MRI image of temporomandibular joints (TMJ) dysfunction on the clinical basis. The study sample comprised 44 patients. All subjects underwent bilateral MRI and unilateral arthroscopy of TMJ to evaluate disc structure, position and function, bone structure abnormalities, joint effusion localization and entity according to Wilkes classification. In 31 patients (70,5%) MRI allowed diagnosing the morphological and functional changes with the arthroscopic confidence. In 13 (29,5%) cases the differences between both images were noted. The stage of the disease was over- or underestimated at one grade level. The present study contributes to an improved understanding of TMJ changes in MRI. The MRI analysis of cranio mandibular disorders is extremely helpful as the primary imaging preceding arthroscopy. (author)

    The aim of this study is to investigate whether virtual MR arthroscopy could be used to visualize the internal architecture of the radiocarpal compartment of the wrist joint in comparison to surgical arthroscopy. Diluted paramagnetic contrast material was injected into the radiocarpal compartment prior to MR examination in all patients. A fat-suppressed T1-weighted three-dimensional fast spoiled gradient echo sequence was acquired in addition to our standard MR imaging protocol in each patient. Three-dimensional data sets were then transferred to an independent workstation and were postprocessed using navigator software to generate surface rendered virtual MR arthroscopic images. Nineteen patients referred for chronic ulnar-sided wrist pain were evaluated with conventional MR arthrography prospectively. Virtual MR arthroscopic images demonstrating the triangular fibrocartilage complex (TFCC) in an intraarticular perspective were achieved in 12 out of 19 patients. Our preliminary investigation suggests that although it has several limitations, virtual MR arthroscopy shows promise in visualizing the TFCC from an intraarticular perspective. (orig.)

    During knee arthroscopy, the transtendinous approach best visualizes articular structures, even though it may cause patellar tendinitis, following the surgical procedures. Thirty patients (22 men and 8 women) who had undergone transtendinous arthroscopy of the knee were submitted to clinical and US follow-up at 3, 6, 12 months. This monitoring was aimed at correlating clinical and instrumental findings of the above iatrogenic condition. Painful symptoms were present in 30% of the cases in group I, in 10% of group II and in no patient in group III. US demonstrated thickening of the patellar tendon in all the three groups of patients, with reduced echogenicity and blurred margins at the arthroscopic portal, plus decreasing gravity over time. The US pattern of arthroscopic surgical gap was observed in all patients in group I, in 10% of patients in group II and in none of the patients in group III. In conclusion because of its clinical course and of its US findings, in our experience patellar tendinopathy following transtendinous arthroscopy of the knee is not to be considered as a iatrogenic inflammatory or degenerative sequela, but as a physiological cicatricial evolution of the surgical transtendinous breach. The US follow-up of the latter allows the correct assessment of the recovering process. PMID:8272543

    Fractures of the distal radius, which currently are treated with palmar locking plates, are often accompanied by carpal lesions. Tears of the scapholunate interosseus ligament (SL) can affect the outcome. Between January 2007 and May 2008, 28 patients with distal intraarticular fractures of the radius were included in a prospective study. Preoperative CT-arthrography was performed. SL tears were found in 11 patients, with 10 partial and one complete rupture observed. A tear of the triangular fibrocartilage complex (TFCC) was detected in 16 patients. Every patient was operated with a palmar locking plate through a palmar approach between the flexor carpi radialis tendon and the radial artery. Then, a palmar wrist arthroscopy using a palmar portal was performed. Eleven SL tears with 9 partial and two total ruptures were diagnosed by arthroscopy. Ten lesions were associated with a C1-fracture with a fracture line projected onto the scapholunate interval. The TFCC was appraisable by palmar wrist arthroscopy only in 4 patients. Three of the SL tears detected by CT-arthrography could not be confirmed by palmar wrist arthroscopy. One complete rupture and one partial lesion confirmed by palmar wrist arthroscopy were found by CT-arthrography to be intact. Palmar wrist arthroscopy affords certainty when assessing the SL ligament. In this study, an assessment of ulnocarpal structures was not possible. For assessment of the ulnocarpal structures, CT-arthrography was superior to palmar wrist arthroscopy. However, the latter is an alternative during emergency treatment or when CT-arthrography is not available. PMID:19790024

  6. Comparison of MR arthrography with arthroscopy of the hip for the assessment of intra-articular loose bodies

    International Nuclear Information System (INIS)

    To assess the specificity and sensitivity of MR arthrography of the hip in comparison with arthroscopy for the evaluation of intra-articular loose bodies. Over a 3-year period, 81 consecutive patients underwent a total of 82 hip arthroscopies by a single orthopedic surgeon for intractable hip pain. Of the 82 arthroscopies, 70 had pre-operative MR arthrograms. Of these, 57 were available for retrospective review, after which they were compared with the operative notes of the subsequent arthroscopies. Of 82 arthroscopies 16 (20%) demonstrated intra-articular loose bodies, while, in the study group, nine of 57 had loose bodies (16%). There was a total of seven discordant cases (five false negatives and two false positives). The sensitivity of MR arthrography for detection of intra-articular loose bodies was 44%, while the specificity was 96%. While the specificity of MR arthrography for the detection of intra-articular loose bodies was high (96%), the sensitivity was not nearly as good (44%). (orig.)

    Eight patients with low-velocity civilian gunshot wounds of the knee were examined and evaluated by arthroscopy. Three of these patients were also treated by surgical arthroscopy and underwent limited arthrotomy for bullet removal. In two patients small arthrotomy incisions were made following arthroscopic exploration for removal of bullets. Two patients underwent diagnostic arthroscopy. One underwent internal fixation for a chondral fracture of the femoral condyle. The majority of patients sustained intra-articular damage and retained foreign materials (denim flecks and metallic shards) and osteochondral fragments. There were no postoperative infections after a minimum follow-up period of one year. Arthroscopy is highly effective in the diagnosis and surgical management of low-velocity gunshot wounds of the knee both alone and in combination with limited arthrotomy depending on the severity of the condylar damage. The length of the hospital stay is reduced (length of stay exceeded 3-4 days only as a result of intravenous antibiotic coverage). Physical therapy requirements are minimal. Active mobility and a full range of motion are regained more rapidly with arthroscopy than with surgical exposure of multiple exploratory incisions or conventional standard arthrotomy. PMID:6705381

    Purpose To provide an efficient learning process, feedback on performance is crucial. In skills laboratories, it is possible to measure the skills and progression of skills of the trainees objectively. This requires metrics that represent the learning curve of the trainee, which were investigated for wrist arthroscopy. The research questions were: What are the forces used by novices during wrist arthroscopy? What aspects of these navigation forces are discriminative for the wrist arthroscopy skills level? Methods A cadaver wrist was mounted in a custom-made distraction device mounted in front of a force platform (ForceTrap). Eleven novices were invited to perform two tasks on the wrist: Insertion of the scope through the 3–4 portal and the hook through the 6R portal, and visualization of the hook in the center of the image Navigation through the wrist from radial to ulnar with probing and visualization of five predefined landmarks The second task was repeated 10 times. The absolute force (F abs) and the direction of force were measured. The angle α is defined in the vertical plane, and the angle β in the horizontal plane. Results The median F abs used by novices remained below the force threshold as defined from the expert data (7.3 N). However, the direction of the applied forces by novices in both planes was not consistent with expert data and showed a wider range. Also, there was no improvement after more trials. Conclusion Our study suggests by the absence of a learning curve for the novices and a significant difference between novices and experts that novices can benefit from feedback on the magnitude and direction of forces to improve their performance.

    International Nuclear Information System (INIS)

    Vascular injuries arising from artroscopy of the knee are very rare, and several large series have reported an incidence of less than 1%. Most vascular injuries involve the popliteal artery or vein, or both. Arthroscopic meniscectomy of the knee is generally a safe and effective procedure with a low rate of vascular complications. We report here on a unique case of a 55-year-old man with a lateral inferior genicular artery pseudoaneurysm and a concomitant arteriovenous fistula that developed after arthroscopic meniscectomy; this was successfully treated with selective angiographic embolization. This case illustrates the effectiveness of an endovascular approach as a minimally invasive treatment for this uncommon complication that occurs after an arthroscopic procedure. Arthroscopy meniscectomy of the knee has become a routine therapeutic procedure. The worldwide clinical experience has proven this technique to be safe, effective and well tolerated by patients, with low rates of morbidity and mortality. The overall complication rate for knee arthroscopy ranges from 0.56% to 8.2%. Vascular injuries are quite rare and they represent less than 1% of all the complications, and most have involved the popliteal artery or vein, or both. There are only a few reports about injuries to the genicular artery during arthroscopic procedures. In this report, we describe a unique case of iatrogenic lateral inferior genicular artery pseudoaneurysm and concomitant arteriovenous fistula that were detected one week after arthroscopic meniscectomy; these lesions were successfully treated with superselective percutaneous transarterial embolization

    Background: Previous authors have suggested that intra-articular morphine and clonidine injections after knee arthroscopy have demonstrated equivocal analgesic effect in comparison with bupivacaine while circumventing the issue of chondrotoxicity. There have been no studies evaluating the effect of intra-articular morphine after hip arthroscopy. Purpose: To evaluate the efficacy of intra-articular morphine in combination with clonidine on postoperative pain and narcotic consumption after hip arthroscopy surgery for femoroacetabular impingement. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective chart review was performed on 43 patients that underwent hip arthroscopy for femoroacetabular impingement at a single institution between September 2014 and May 2015. All patients received preoperative celecoxib and acetaminophen, and 22 patients received an additional intra-articular injection of 10 mg morphine and 100 μg of clonidine at the conclusion of the procedure. Narcotic consumption, duration of anesthesia recovery, and perioperative pain scores were compared between the 2 groups. Results: Patients who received intra-articular morphine and clonidine used significantly less opioid analgesic (mEq) in the postanesthesia recovery (median difference, 17 mEq [95% CI, –32 to –2 mEq]; P = .02) compared with the control group. There were no differences in time spent in recovery before hospital discharge or in visual analog pain scores recorded immediately postoperatively and at 1 hour after surgery. Conclusion: Intraoperative intra-articular injection of morphine and clonidine significantly reduced the narcotic requirement during the postsurgical recovery period after hip arthroscopy. The reduction in postsurgical opioids may decrease adverse effects, improve overall pain management, and lead to better quality of recovery and improved patient satisfaction. PMID:26977421

    Background There are many different materials used for ligament reconstruction. Currently, autograft, allograft, and artificial ligaments are used in the reconstruction. The objective of this study was to explore the clinical result of cruciate ligament reconstruction under arthroscopy.Methods Eighty-one cases were reconstructed with the LARS ligament under arthroscopy, including 43 cases of anterior cruciate ligament (ACL) injury, 20 cases of posterior cruciate ligament (PCL) injury, and 18 cases of ACL combined with PCL injuries of the knee. The follow up period was 10 to 49 months. The International Knee Documentation Committee (IKDC) and Lysholm knee score scales were used for functional evaluation. We examined the anterior and posterior stability of the knee with KT-1000.Results According to the Lysholm knee function score scale, the average preoperative score of (44.6±1.4) increased to a postoperative score of (82.8±2.5) in the ACL group and from (46.6±2.3) to (80.8±2.0) in the PCL group. In the ACL combined with PCL injury group, the preoperative score increased from (45.2±1.2) to (85.5±2.3). According to IKDC score standards, in ACL group we evaluated 19 cases as C and 24 cases as D, preoperatively, and postoperatively 27 cases as A, 14 cases as B and two cases as C. In the preoperative PCL group, we had 11 cases defined as C and nine cases as D that resolved to 12 cases as A, seven as B and one case of C in postoperative evaluation. In the ACL combined with PCL injury group we defined four cases as C and 14 as D during preoperative scoring. These patients had postoperative grades of six cases as A, 10 as B, and two cases as C. All of the results have statistical significance. Conclusions ACL, PCL, or combined ACL and PCL reconstruction using the LARS ligament under arthroscopy is a minimally invasive, safe and effective method to treat cruciate ligament injuries of the knee. Clinical results are satisfactory in the short term.

    Objectives: Cam-type femoroacetabular impingement (FAI) causes a shearing and delamination injury to the acetabular articular cartilage due to a mismatch between the size of the femoral head and the acetabulum. This mechanism is thought to lead to early osteoarthritis in this population. Cam decompression has been advocated to eliminate impingement, with the ultimate goal of halting the progression of articular cartilage delamination. Although outcomes following this procedure in the young adult population have been favorable at short and medium term follow up, it is not known whether the articular cartilage itself is protected from further injury by changing the biomechanics of the joint with decompression of the cam morphology. The purpose of this study is to compare the pre- and post-operative integrity of the acetabular articular cartilage using T2 mapping to determine if hip arthroscopy is protective of the articular cartilage at short- to medium term follow up. Methods: Males between 18 and 35 years of age who had pre-operative T2 mapping MRIs, underwent hip arthroscopy for cam or mixed-type FAI with an alpha angle greater than 50°, and had at least 2 year follow-up were identified. Post-operative MRIs were performed and T2 relaxation times in the transition zone and weight bearing articular cartilage in the anterosuperior acetabulum at deep and superficial chondral layers were recorded at nine points on three sagittal sequences on pre and post-operative MRIs. A paired t-test was used to compare T2 relaxation values between pre-operative and post-operative scans. Results: Eleven hips were evaluated. Mean age was 26.3 years (range 21 - 35). Mean follow up time to post-operative T2 mapping MRI was 2.6 years (range 2.4 - 2.7). The change in T2 relaxation time was not significantly different between pre- and post-operative MRI scans for any of the nine regions in the deep zone of the acetabular cartilage (p=0.065 - 0.969) or the superficial zone of the

  1. Clinical, epidemiological and endoscopic characteristics of the synovial plica in patients with arthroscopy

    International Nuclear Information System (INIS)

    A prospective study of patients with surgical treatment of the knee through arthroscopy was carried out at the Rheumatology Service, belonging to 'Saturnino Lora' Teaching Clinical Surgical Provincial Hospital from Santiago de Cuba during the years 2000-2009; a decade in which 663 knees were surgically treated and, 208 due to a synovial plica. This last one turned out to be the most frequent disease, with predominance in the female sex and the ages from 16 to 25 years. There was a marked clinicoarthroscopic correspondence. Preoperative diagnosis consisted of lesion of the internal meniscus, chondromalacia patellae and synovitis, reason why they should be kept in mind as differential diagnosis in this syndrome. The way of healing the surgical section of the synovial plica is the cause of symptomatic relapse and surgical reintervention, as it happened in the patients of the case material 54,0 %, mainly attributable to fibrosis in the wound area.(author)

  2. Comparison between arthroscopy and magnetic resonance studies of rupture of the anterior cruciate ligament of the knee

    International Nuclear Information System (INIS)

    To compare the reliability of magnetic resonance (MR) in the diagnosis of rupture of the anterior cruciate ligament (ACL) with that of arthroscopy in a large series of patients. A series of 149 patients underwent arthroscopy and MR study of the knee. The condition of the ACL was classified as normal, partial rupture (increased signal in the ligament with integral hypointense fibers) or complete rupture (complete interruption or failure to visualize the ligament). The agreement (kappa), sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. MR images of ACL were normal in 114 of 116 normal cases; partial rupture was observed in 4 cases (versus 3 in arthroscopy) and complete rupture in 31 (versus 30 in arthroscopy). The agreement was excellent (kappa: 0.93; p < 0.001). For the diagnosis of normal ACL, the sensitivity of MR was 1, the specificity 0.98, the PPV 0.94 and the NPV 1. For the diagnosis of partial rupture, the sensitivity was 0.67, the specificity 0.98, the PPV 0.50 and the NPV 0.99. For complete rupture, the sensitivity was 0.97, the specificity 0.98, the PPV 0.94 and the NPV 0.99. The high sensitivity and specificity of MR observed in the diagnosis of integral ACL is somewhat reduced in cases of complete rupture and even lower in cases of partial rupture. It is important to differentiate the degree of rupture since the therapeutic management of the patient differs. (Author) 18 refs

    Full Text Available Background/Objective: The concept of evaluating the musculoskeletal system with ultrasound was initially introduced in the late 1970s. For evaluating meniscal tears, which are a common injury in traumatic events of knee, linear probes with high resolution have been used. In this study, we compared the results of sonography with arthroscopy in diagnosing bucket handle tear of meniscus and MCL tear. Patients and Methods: 218 clinically symptomatic knee joints with clinical indication of arthro-scopy were examined by sonography in a referral sport medicine center. The patients eventually had arthroscopic exam. The results were compared, and statistically analyzed using Fisher’s exact. Results: In this study, of 218 patient who had arthroscopy and sonography, the sensitivity and specificity of sonography in meniscal tear were 68.1% and 100%, respectively. 34 patients had bucket handle tear of the posterior horn of the medial meniscus on sonography; six cases (17.6% of which had abnormally small posterior horns of medial meniscus (in favor of meniscal tear but in 60 patients with other types of meniscal tear, sonography revealed tear in 58 (96.6%(P<0.0001. Six patients had complete MCL tear in arthroscopy, while in sonography 4 complete MCL tears were shown. Sensitivity of ultrasound in diagnosing complete MCL tear was 66.6% and specificity of 98%. Conclusion: Ultrasound is easily applicable in evaluation of knee derangement: however, for bucket handle tears it has limited application. For MCL tears, sonography seems an accurate method. Ultrasonography is rapid, low-cost and non-invasive examination.

    5Objective:To evaluate the values of spiral CT arthrography with multiplanar reconstruction and virtual arthroscopy technique in diagnosis of internal derangements of the knee. Methods:Ten bovine knees were used for experiment. The menisci, anterior and posterior cruciate ligaments and cartilage of these 10 bovine knees were injured with a hook. Each of the joints was injected with 100 mi air, then soon scanned with a PQ6000 spiral computed tomography scanner. The data obtained was input into the work station, and multiplanar reconstruction technique was used to illustrate lesions in the knees. The results of CT diagnosis were compared to those found by gross inspection of the specimens. Clinically, 10 knees of 9 patients diagnosed as internal derangement were evaluated with the same method after 50-70 ml air was injected into each of the joints. Nine months later, the data of 2 patients were used for CT endoscopy reconstruction. The results were compared with intraoperative findings. Results:Experimentally,the sensitivity and specificity were 88.9% and 93.9% by detection of meniscal abnormalities, 85.7% and 100% by detection of cruciate ligament lesions, and 72.7% and 100% by detection of cartilage damage, respectively. Clinically, the sensitivity and specificity were 90. 0% and 95.0% by detection of meulscal lesion. As to ligament, the figures were 85.7% and 100% respectively. Images of virtual arthroscopy simulated the images of real arthroscopy. Conclnsious:Spiral CT arthrography of multiplanar reconstruction technique offers fime images of internal structures of the knee, with clear border and internal structure. It is an accurate method for detecting meulscal, cruciate and collateral ligament and cartilaginous lesions that cause internal derangement of the knee.Virtual arthroscopy technique is a hopeful method for detecting reasons of derangement of the knee.

    Despite being one of the most common orthopaedic operations, it is still not known how many arthroscopies of the knee must be performed during training in order to develop the skills required to become a Consultant. A total of 54 subjects were divided into five groups according to clinical experience: Novices (n = 10), Junior trainees (n = 10), Registrars (n = 18), Fellows (n = 10) and Consultants (n = 6). After viewing an instructional presentation, each subject performed a simple diagnostic arthroscopy of the knee on a simulator with visualisation and probing of ten anatomical landmarks. Performance was assessed using a validated global rating scale (GRS). Comparisons were made against clinical experience measured by the number of arthroscopies which had been undertaken, and ROC curve analysis was used to determine the number of procedures needed to perform at the level of the Consultants. There were marked differences between the groups. There was significant improvement in performance with increasing experience (p skills of a Consultant. We suggest that this approach to identify what represents the level of surgical skills of a Consultant should be used more widely so that standards of training are maintained through the development of an evidenced-based curriculum.

    Elbow arthroscopy has become a safe and effective treatment option for a number of elbow disorders. The most rewarding and successful indication is the removal of loose bodies. Loose bodies are often a result of osteochondritis dissecans (OCD) of the capitellum, and arthroscopy in this case is useful for performing debridement, thereby eliminating the need for a more extensive open procedure associated with complications. In this review, we describe our arthroscopic technique for OCD of the capitellum. We usually conduct arthroscopy in the supine position, and use 2.9-mm arthroscopes of 30° and 70°. The 70° arthroscope provides a greater operative field than the 30° arthroscope. Arthroscopic treatment for OCD may require 2 anterior and 2 posterior portals. Loose bodies are commonly found in the radial fossa, coronoid fossa, and in the olecranon fossa. Once the loose bodies are removed, all unstable cartilage of the capitellum lesion is removed to create a stable bed. If any sclerotic changes to the lesion bed are observed, we create microfractures in the lesion bed. The most significant complication in arthroplasty is neurovascular injury. However, we have never experienced this devastating complication, which can be avoided by paying careful attention to detail. PMID:25264040

    Objective: To evaluate operative effects of a new method to reconstruct anterior crucial ligament (ACL) and posterior crucial ligament (PCL) simultaneously by using patellar tendon under arthroscopy.Methods: From November 1999 to November 2003,the injured ACL and PCL of 11 patients were fixated with compressed screws and reconstructed under arthroscopy with the bone-patellar tendon-bone treated with deep hypothermia and T radiation. At the same time, 2 patients were treated with medial collateral ligament (MCL)reconstruction, 3 with lateral collateral ligament (LCL)reconstruction, 1 with meniscus suture and 4 with whole or partial resection.Results: All patients were followed up for 12-26months (average 16.5 months ). The Lysholm score method was employed to evaluate the knee function. The average preoperative score was 45.3 and the postoperative score was 86.4. Anterior drawer test (ADT) was positive in 11 knees preoperatively and feeble positive in one knee postoperatively. Lachman test was positive in 11 knees preoperatively and in one postoperatively, and feebly positive in two postoperatively. Posterior drawer test was positive in 11 knees preoperatively and feebly positive in 2postoperatively. There were 2 knees with tolerable pain and 2 with knee flexion of 5°-20°.Conclusions: As for simultaneous reconstruction of ACL and PCL under arthroscopy, ailogeneic bone-patellar tendon-bone can not only avoid injury and complication caused by autografting, but also help rehabilitation of the knee function.

    The purpose of this paper is to retrospectively review 234 consecutive cases of scaphoid fractures and nonunions treated using arthroscopy with the dorsal percutaneous implantation of a headless compression screw for healing and complications. Solid union of fracture is determined by CT scan. We identified 126 acute injuries, including 65 proximal pole fractures; 67 grossly displaced fractures; 12 trans-scaphoid perilunate dislocations including four trans-scaphoid trans-capitate fractures; and ten combined scaphoid and distal radius fractures. 108 scaphoid nonunions were identified. 98 were correctly aligned and ten had a humpback deformity which was correctable using arthroscopic assisted reduction techniques at the time of surgery. 82 presented with a fracture gap 2mm or greater requiring percutaneous bone grafting. 12 cases of avascular necrosis (AVN) were identified by MRI. 20 nonunions had surgery performed at other institutions. The mean time to surgery for the nonunions was 20 months. 99% union rate of acute scaphoid fractures was obtained by 12 weeks, as determined by CT scan. Two complications were identified (3%). One case of delayed healing was identified. this delayed union was treated with percutaneous bone grafting and continued on to heal uneventfully. The other complication was a case of volar trans-scaphoid peri-lunate dislocation. While the fracture healed, the patient developed a traumatic dislocation requiring a capitate-lunate arthrodesis. Treatment of scaphoid nonunions resulted in ten cases of delayed healing, which were treated with repeat percutaneous bone grafting. This represented a 9% complication rate. of the ten cases of delayed unions that were re-bone grafted, four failed to heal by nine months. This resulted in a 96% union rate of our nonunion group by nine months. when acute fracture healing was compared to nonunions the average healing of acute fractures as determined by CT scanning measuring trabecular bridging was 12 weeks

Its use in the diagnosis and treatment of the hip injury get more notably. Many of pathologic conditions previously unrecognized through X-ray,CT or MRI have been diagnosed correctly under hip arthroscopy. The technology has become gradually a golden standard to confirm the hip discords. In the present, the examining path of the hip arthroscopy contains mainly the outside path, the anterior path, the outside-posterior path. The application range of the hip arthroscopy includes the management of labral tears, the femoroacetabular impingement, the ligamentum tear injuries,the chondral lesions,the synovical abnormalities,the intra-articular infection,the loose bodies in the joint etc. The hip arthroscopy is a comprehensive technology. Its superiority can be reflect well if the doctors are familiar with the indication,the contraindication and the operation procedure. And also the thorough physical examination and imaging examination should be made before operation,as well as reasonable and effective postoperative function training should be conducted.

    Hip disorders are increasingly recognized among athletic populations. The rigors of military service expose individuals to the same risks as those participating in competitive sports, compounded by potential exposure to violent macrotrauma. This is a retrospective review of prospectively collected data among 62 active duty military personnel (64 hips) with 2-10-year follow-up. Follow-up averaged 47 months (range 24-120 months). The average age was 30 years (range 17-53 years) with 45 males and 17 females; 37 right and 27 left hips. Duration of symptoms prior to arthroscopy averaged 28 months (range 6-168 months). The average improvement was 22 points (pre-op 63; post-op 85) using the 100-point modified Harris hip score and was statistically significant (P ulnar nerve neurapraxia and superficial sensory dysesthesias of the foot, both of which resolved within a few days. This is a heterogeneous cohort of pathology, but illustrates that hip disorders may exist among active duty military personnel and may benefit from arthroscopic intervention. A sense of awareness is important for accurate diagnosis and timely treatment. PMID:27026823

    We compared naproxen sodium (550 mg) and propoxyphene napsylate with acetaminophen (PN/A, 100 mg with 650 mg) for pain relief after arthroscopy or arthroscopic meniscectomy. Fifty-two patients entered this multicenter, double-blind, randomized, parallel trial. In each drug group, pain intensity values dropped consistently throughout this six-hour study from mean baseline levels of approximately 55 on a scale of 0 to 100. Pain intensity values were lower at each hour in the naproxen sodium than in the PN/A group and significantly lower at hour 1 (P = .008). Pain intensity differences (PID, reflecting change from baseline) mirrored this trend: greater mean PIDs were seen in the naproxen sodium group at each hour, and this difference between drug groups was statistically significant at hour 1 (P = .017). One patient in the naproxen sodium group and seven patients using PN/A took a second dose within the six hours. Patients in each drug group reported five complaints. PMID:2882607

    The significance of subtle changes in signal intensity on MR images of the meniscus is not clear, as the authors have a high rate of false-negative diagnoses using previously reported criteria. Unselected patients scheduled for knee arthroscopy were imaged in sagittal and coronal planes (repetition time/echo time = 800-1,500/20, 70 msec) with 5-mm and 3-mm section thickness, respectively. A total of 140 menisci were evaluated. The images and interpretations were withheld from the arthroscopist until the arthroscopic diagnosis was recorded so that the MR imaging results did not influence which cases received arthroscopic confirmation. Before the arthroscope was withdrawn the MR images and interpretations were unsealed so that additional arthroscopic evaluation could be obtained of areas suspicious on MR imaging. Review of the first 60 menisci showed that significant tears of the meniscus were often represented by subtle signal intensity that did not extend to the surface of the meniscus. When previously reported criteria were used, approximately 50% of those menisci with increased internal signal not extending to the surface were interpreted as false-negative diagnoses. An initial classification system based on ten categories of signal morphology was developed which reduced the false-negative rate to 10% but led to a 30% rate of false-positive diagnoses in those cases with equivocal signal. Retrospective, blinded categorization of signal morphology was optimized based on ROC curves, and this is being tested prospectively in an ongoing investigation

Finally, a pass-or-fail standard was set with use of the contrasting groups method, and the consequences of the pass-or-fail standard were explored. RESULTS: One procedure was excluded from the final test because of a lack of validity. The total Z-scores for...... the four procedures included in the final test showed an intercase reliability of 0.87 (95% confidence interval, 0.78 to 0.93). The total mean z-score (and standard deviation) was 38.6 ± 27.3 points for the novices and 0.0 ± 9.1 points for the experienced surgeons (p < 0.0005). The pass......-or-fail standard was set at a total z-score of 15.5 points, resulting in two of the novices passing the test and a single experienced surgeon failing the test. CONCLUSIONS: By combining four procedures on a virtual reality arthroscopy simulator, it was possible to create a valid, reliable, and feasible test of...

    Highlights: • MR is the preferred imaging modality for diagnosing acetabular labral tears. • The diagnostic performance of MR arthrography are superior than conventional hip MR. • The hip MR arthrography is recommended for diagnosing acetabular labral lesions. - Abstract: Objective: To evaluate the value of hip MR for diagnosing acetabular labrum tears, and to further compare the diagnostic performances of conventional MR with MR arthrography in acetabular labrum tears. Methods: 90 patients undergoing both hip MR examination and subsequent hip arthroscopy were retrospectively evaluated. Of these patients, 34 accepted both conventional MR and MR arthrography; while the other 56 only underwent conventional MR examination. All hip MR images were independently reviewed by two radiologists, and further compared with the results of hip arthroscopy. Results: 59 of 90 patients were confirmed with acetabular labral tears by hip arthroscopy and 31 without tears. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of conventional MR for evaluating the acetabular labral tears were 61.0%, 77.4%, 83.7% and 51.1% (radiologist A), and 66.1%, 74.2%, 82.9% and 53.4% (radiologist B), respectively, with good consistency between the two observers (K = 0.645). The sensitivity, specificity, PPV and NPV of MR arthrography for assessing the acetabular labral tears were 90.5%, 84.6%, 90.5% and 84.6% (radiologist A), and 95.2%, 84.6%, 90.9% and 91.7% (radiologist B), respectively, with excellent good consistency between the two observers (K = 0.810). The sensitivity and NPV of MR arthrography for diagnosing the acetabular labral tears were significantly higher than those of conventional MR (both P < 0.05). Conclusion: Hip MR arthrography is a reliable evaluation modality for diagnosing the acetabular labral tears, and its diagnostic performance is superior to that of conventional MR at 3.0 T.

    Full Text Available INTRODUCTION: Shoulder arthroscopy is a common orthopedics procedure performed on day - case basis. Adequate pain relief reduces surgical stress response, patient’s morbidity and improves postoperative recovery and rehabilitation. Various drugs have been tried intra - articularly t o provide postoperative analgesia. PURPOSE: We studied analgesic effect of dexamethasone 16mg (4ml with ropivacaine and compared it with ropivacaine intra - articularly in shoulder arthroscopic procedures in search of the ideal analgesic combination. METHODS: A Prospective Multicenter Double Blind study on 60 patients undergoing arthroscopic shoulder surgery from July’13 - April’14. Patients were assigned into 3 groups randomly - Group I (20 ml normal saline,Group II (20 ml 0.2% ropivacaine and Group III (16 ml 0.2% of ropivacaine & dexamethasone - 4 ml containing 16 mg. VARIABLES ASSESSED: Analgesic effect (VAS Score, time to first postoperative analgesic request, Analgesic used during first 24 hours. RESULTS: Group III had significant low pain scores for 1 st 20 hours as compared to Group II and Group I. Time to first analgesic requirement was longest in Group III (1356.2±193.10mins (p<0.01. Intensity of pain &Total analgesic requirement was significantly less in Group III (38.2±27.83 mg(p<0.01 in comparison to Group II and I. No significant side - effects were noted. CONCLUSION: A16 mg (4ml dosage of Dexamethasone is safe, cost effective and free from relative side effects, has a better patient compliance in terms of post - operative pain, need for analgesia and should be used routinely in arthroscopic shoulder surgeries. Helps in the recovery of patients to the pre - operative level.

    Abstract: The optimum anaesthetic and analgesic management following hip arthroscopy is yet to be determined. There is, in addition, some concern over the use of intraarticular local anaesthetic. We compared the analgesic efficacy of intra-articular infiltration compared with portal infiltration of bupivacaine following hip arthroscopy. Patients were randomised to receive either 10ml of 0.25% bupivacaine either into the joint or around the portal sites following completion of surgery. 73 patients were recruited (40 intra-articular). The portal infiltration group required significantly more rescue analgesia immediately after surgery (2.33mg vs.0.57mg, p=0.036). Visual Analogue Scale pain scores were not significantly different at 1 and 2 hours following surgery, but at 6 hours the portal group had significantly lower VAS scores (p=0.0036). We believe that the initial pain following surgery results from capsular injury and this explains the need for more rescue analgesia in the portal infiltration group. Further work is needed to establish the ideal regimen. A combination of portal and intra-articular infiltration may be the most efficacious.

    Health care facilities produce significant waste (2200 kg/bed/year) creating 2% of greenhouse gas emissions and 1% total solid waste nationwide, with 20-70% of waste coming from operating rooms. We performed a waste audit of hip arthroscopy for femoroacetabular impingement (FAI) to understand its environmental impact and identify areas for greening practices. A waste audit of five hip arthroscopy procedures for FAI was performed. All waste was collected and separated into six waste streams in real time: (i) normal/landfill waste; (ii) recyclable cardboards and plastics; (iii) biohazard waste; (iv) sharp items; (v) linens and (vi) sterile wrapping. The surgical waste (except laundered linens) from five FAI surgeries totaled 47.4 kg, including 21.7 kg (45.7%) of biohazard waste, 11.7 kg (24.6%) of sterile wrap, 6.4 kg (13.5%) of normal/landfill waste, 6.4 kg (13.5%) of recyclable plastics and 1.2 kg (2.6%) of sharp items. An average of 9.4 kg (excluding laundered linens) of waste was produced per procedure. Given the considerable biohazard waste produced by FAI procedures, additional recycling programs, continued adherence to proper waste segregation and an emphasis on 'green outcomes' is encouraged to demonstrate environmental responsibility and effectively manage and allocate finite resources.

    Full Text Available Background and Aims: Sudden, profound hypotension and bradycardia events (HBEs have been reported in more than 20% of patients undergoing shoulder arthroscopy in the sitting position. The present study was designed to know whether intravenous (IV ondansetron (selective 5-hydroxy tryptamine 3-antagonist can help in reducing the HBEs associated with shoulder arthroscopy performed in sitting position under interscalene brachial plexus block (ISBPB. Methods: A total of 100 patients (age 20-50 years undergoing shoulder arthroscopy performed in the sitting position under ISBPB were assigned randomly to one of the two groups: Group C received 10 ml of normal saline and Group T received 4 mg of ondansetron diluted in 10 ml of normal saline` IV. All patients received ISBPB using levobupivacaine 0.5%. Assessment of motor and sensory blockade, pulse rate, systolic blood pressure, respiration, and side effects were noted every 5 min for first 30 min and every 10 min till the end of surgery. HBEs were recorded in both groups. Results: IV injection of ondansetron significantly reduces the incidence of HBEs from 11 (22.44% in Group C to 3 (6.1% in Group T. The duration of analgesia was significantly longer in Group C (8.1 ± 3.3 in comparison with Group T (6.3 ± 4.2 h. Conclusion: We conclude that 4 ml of IV ondansetron can significantly reduce the HBEs during shoulder arthroscopy done in the sitting position under ISBPB.

  20. Conventional angiography in comparison with magnetic resonance tomography and arthroscopy for the diagnosis of knee joint lesion - specific indications?

    International Nuclear Information System (INIS)

    Twenty-one patients with suspected internal knee joint lesions were examined prospectively. In all patients an MRI was carried out first and was followed within two weeks by an arthrography and an arthrocopy. Lesions of the menisci, cruciate ligaments, hyaline cartilage, and synovial tissues were evaluated. Arthroscopy findings were defined as the 'gold standard'. MRI achieved an accuracy of 96.4%, a sensitivity of 93.6%, and a specifity of 92.5%, whereas arthrography achieved an accuracy of 67.8%, a sensitivity of 66.6%, and a specifity of 71.4%. These statistical data as well as the single findings revealed no special indications for arthrography in suspected knee joint lesions. (orig.)

    2010-10-01

    Full Text Available Abstract Background Surgery for type II SLAP (superior labral anterior posterior lesions of the shoulder is a promising but unproven treatment. The procedures include labral repair or biceps tenodesis. Retrospective cohort studies have suggested that the benefits of tenodesis include pain relief and improved function, and higher patient satisfaction, which was reported in a prospective non-randomised study. There have been no completed randomised controlled trials of surgery for type II SLAP lesions. The aims of this participant and observer blinded randomised placebo-controlled trial are to compare the short-term (6 months and long-term (2 years efficacy of labral repair, biceps tenodesis, and placebo (diagnostic arthroscopy for alleviating pain and improving function for type II SLAP lesions. Methods/Design A double-blind randomised controlled trial are performed using 120 patients, aged 18 to 60 years, with a history for type II SLAP lesions and clinical signs suggesting type II SLAP lesion, which were documented by MR arthrography and arthroscopy. Exclusion criteria include patients who have previously undergone operations for SLAP lesions or recurrent shoulder dislocations, and ruptures of the rotator cuff or biceps tendon. Outcomes will be assessed at baseline, three, six, 12, and 24 months. Primary outcome measures will be the clinical Rowe Score (1988-version and the Western Ontario Instability Index (WOSI at six and 24 months. Secondary outcome measures will include the Shoulder Instability Questionnaire (SIQ, the generic EuroQol (EQ-5 D and EQ-VAS, return to work and previous sports activity, complications, and the number of reoperations. Discussion The results of this trial will be of international importance and the results will be translatable into clinical practice. Trial Registration [ClinicalTrials.gov NCT00586742

    Objective: To evaluate fat-suppressed (FS) proton-density-weighted (PDw) turbo spin-echo (TSE) magnetic resonance imaging for the detection of anterior and posterior cruciate ligament lesions in comparison to arthroscopy. Materials and methods: In a prospective study 31 knee joints were imaged on a 1.5 T MR scanner (Vision[reg], Siemens, Erlangen) prior to arthroscopy using following sequences: (a) sagittal FS-PDw/T2w TSE (TR/TE: 4009/15/105 ms); (b) sagittal PDw/T2w TSE (TR/TE:3800/15/105 ms). Further imaging parameters: slice thickness 3 mm, FOV 160 mm, matrix 256 x 256. A total of 62 anterior and posterior cruciate ligaments (ACL/PCL) were evaluated, standard of reference was arthroscopy. Sensitivity, specificity, positive (ppv) and negative predictive value (npv) and accuracy were calculated. Results: Twenty-one cruciate ligament ruptures were detected in arthroscopy, 19 ACL- and 2 PCL-ruptures (on MRI 34/124, 25/62 ACL, 9/62 PCL lesions). For all four sequences in the 31 patients with arthroscopic correlation sensitivity, specificity, ppv, npv and accuracy were 86%, 98%, 95%, 93% and 94% for detection of tears, and 84%, 100%, 100%, 80% and 90% for ACL-ruptures respectively. The two PCL-ruptures were true positive in all sequences, one intact PCL was diagnosed as torn (false positive). Conclusions: Fat-suppressed PDw/T2w TSE-MR sequences are comparable to PDw TSE sequences for the detection of ACL/PCL-lesions.

    The role of arthroscopy in the treatment of soft-tissue injuries associated with proximal tibial fractures remains debatable. Our hypothesis was that MRI over-diagnoses clinically relevant associated soft-tissue injuries. This prospective study involved 50 consecutive patients who underwent surgical treatment for a split-depression fracture of the lateral tibial condyle (AO/OTA type B3.1). The mean age of patients was 50 years (23 to 86) and 27 (54%) were female. All patients had MRI and arthroscopy. Arthroscopy identified 12 tears of the lateral meniscus, including eight bucket-handle tears that were sutured and four that were resected, as well as six tears of the medial meniscus, of which five were resected. Lateral meniscal injuries were diagnosed on MRI in four of 12 patients, yielding an overall sensitivity of 33% (95% confidence interval (CI) 11 to 65). Specificity was 76% (95% CI 59 to 88), with nine tears diagnosed among 38 menisci that did not contain a tear. MRI identified medial meniscal injuries in four of six patients, yielding an overall sensitivity of 67% (95% CI 24 to 94). Specificity was 66% (95% CI 50 to 79), with 15 tears diagnosed in 44 menisci that did not contain tears. MRI appears to offer only a marginal benefit as the specificity and sensitivity for diagnosing meniscal injuries are poor in patients with a fracture. There were fewer arthroscopically-confirmed associated lesions than reported previously in MRI studies. PMID:25452365

  7. MR imaging of the articular cartilage of the knee with arthroscopy as gold standard: assessment of methodological quality of clinical studies

    International Nuclear Information System (INIS)

    The purpose of this study was to assess the methodological quality of articles addressing the value of MR imaging of the knee cartilage with arthroscopy as a standard. Relevant papers were selected after Medline review (MEDLINE database search including the terms ''cartilage'' ''knee'', ''MR'' and ''arthroscopy''). Two observers reviewed independently 29 selected articles to determine how each study had met 15 individual standards that had been previously developed to assess the methodological quality of clinical investigations. The following criteria were met in variable percentage of articles including adequate definition of purpose (100%), statistical analysis (90%), avoidance of verification bias (86%), patient population description (83%), reference standard (79%), review bias (79%), study design (66%), inclusion criteria (41%) and method of analysis (41.5%), avoidance of diagnostic-review bias (24%), exclusion criteria (21%), indeterminate examination results (17%), analysis criteria (14%), interobserver reliability (14%) and intraobserver reliability (7%). The assessment of the methodological quality of clinical investigations addressing the value of MR imaging in the evaluation of the articular cartilage of the knee with arthroscopy as the standard of reference demonstrated that several standards were rarely met in the literature. Efforts should be made to rely on clearly defined lesion criteria and to determine reliability of the observations. (orig.)

  8. Clinical significance of bone bruises and cartilage lesions associated with anterior cruciate ligament injuries by magnetic resonance imaging and arthroscopy

    International Nuclear Information System (INIS)

    In 85 patients with anterior cruciate ligament (ACL) rupture, we examined bone bruises retrospectively using magnetic resonance imaging (MRI). In 53 patients who underwent arthroscopy, the bone bruises were compared with the cartilage lesions. Depending on the time from their ligamentous injury to the performance of MRI, the patients were divided into three groups: the acute group (less than 1 months, n=29), the subacute group (between 1 and 12 months, n=29), and the chronic group (12 months or more, n=27). The detection rate of bone bruises by MRI was significantly higher in the acute group than in the other groups (p<0.0001). Bone bruises were always detected in the same locations of the lateral compartment of the knee joint. In four patients who observed bone bruises in the first MRI and underwent follow-up MRI 3-6 months later, bone bruises had disappeared in the follow-up MRI. In the acute group, bone bruises in the lateral femoral condyle were often found to be accompanied by cartilaginous injuries. In the subacute and chronic groups, the rate of degeneration of these cartilaginous lesions had progressed. (author)

  9. Diagnoses of meniscal and cruciate ligament injuries using magnetic resonance imaging of the knee. Comparison with the findings of arthroscopy

    International Nuclear Information System (INIS)

    As previously reported, MRI is found to be useful in the evaluation of meniscal and cruciate ligament injuries. But at our institute, however, due to frequent in consistencies between MRI and arthroscopic findings, we investigated problem knees by MRI and compared the findings with those using arthroscopy subsequently performed. Twenty-eight cases with medial and lateral meniscus, and 31 cases with anterior and posterior crucial ligament were examined. The field strength of MRI was 1.0 Tesla, and images were measured by the T2 weighted gradient echo method. Sensitivity for medial meniscus, lateral meniscus, anterior cruciate ligament, and posterior cruciate ligament was 60, 38, 33, and 20 percent respectively, specificity was 78, 90, 91, and 89 percent respectively, and accuracy was 75, 75, 74, and 77 percent respectively. These values are lower compared with other reports. Diagnoses of meniscal and cruciate ligament injuries from magnetic resonance imaging of the knee at our institute are not confidential. For improvement, the scanning and imaging methods, must be changed and a new sophisticated MRI scanner is desirable. (author)

  10. Relationship between mucoid hypertrophy of the anterior cruciate ligament (ACL) and morphologic change of the intercondylar notch: MRI and arthroscopy correlation

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the relationship between mucoid hypertrophy of the anterior cruciate ligament (ACL) and morphologic change of the intercondylar notch. We retrospectively reviewed the 105 patients with knee magnetic resonance imaging (MRI) with or without knee arthroscopy [group 1: patients with arthroscopic notchplasty (N = 47), group 2: knee arthroscopy demonstrating intact ACL (N = 33), and group 3: patients with normal knee MRI but no arthroscopy (N = 25)]. Groups 2 and 3 served as an arthroscopic and MR control group, respectively. Two musculoskeletal radiologists reviewed all MR examinations. The intercondylar notch width, notch index (width of intercondylar notch/width of femoral condyle), transverse notch angle (TNA), sagittal notch angle (SNA), and notch area were recorded on axial and sagittal MR images at the midpoint of Blumensaat's line which was identified on sagittal images. The diameter of the ACL was recorded on coronal MR images at the posterior end of Blumensaat's line. The mean values of the intercondylar notch width, notch index, TNA, SNA, notch area, and ACL diameter for the three groups were 16.0 mm/0.2/50.3 /36.5 /249.0 mm2/7.7 mm (group 1); 19.3 mm/0.3/52.9 /40.2 /323.4 mm2/4.8 mm (group 2); and 20.3 mm/0.3/51.4 /39.1 /350.8 mm2/4.5 mm (group 3). The intercondylar notch width, notch index, SNA, and notch area were smaller, and ACL diameter was thicker in group 1 compared with the other groups (p < 0.05). Patients with mucoid ACL hypertrophy show a narrower notch, a steeper notch angle, and a smaller notch area than control groups. (orig.)

    Full Text Available Abstract Background In patients with osteoarthritis, a detailed assessment of degenerative cartilage disease is important to recommend adequate treatment. Using a representative sample of patients, this study investigated whether MRI is reliable for a detailed cartilage assessment in patients with osteoarthritis of the knee. Methods In a cross sectional-study as a part of a retrospective case-control study, 36 patients (mean age 53.1 years with clinically relevant osteoarthritis received standardized MRI (sag. T1-TSE, cor. STIR-TSE, trans. fat-suppressed PD-TSE, sag. fat-suppressed PD-TSE, Siemens Magnetom Avanto syngo MR B 15 on a 1.5 Tesla unit. Within a maximum of three months later, arthroscopic grading of the articular surfaces was performed. MRI grading by two blinded observers was compared to arthroscopic findings. Diagnostic values as well as intra- and inter-observer values were assessed. Results Inter-observer agreement between readers 1 and 2 was good (kappa = 0.65 within all compartments. Intra-observer agreement comparing MRI grading to arthroscopic grading showed moderate to good values for readers 1 and 2 (kappa = 0.50 and 0.62, respectively, the poorest being within the patellofemoral joint (kappa = 0.32 and 0.52. Sensitivities were relatively low at all grades, particularly for grade 3 cartilage lesions. A tendency to underestimate cartilage disorders on MR images was not noticed. Conclusions According to our results, the use of MRI for precise grading of the cartilage in osteoarthritis is limited. Even if the practical benefit of MRI in pretreatment diagnostics is unequivocal, a diagnostic arthroscopy is of outstanding value when a grading of the cartilage is crucial for a definitive decision regarding therapeutic options in patients with osteoarthritis.

    All simple arthroscopic procedures during 1999 through 2001 performed at Baerum community hospital were retrospectively examined. Procedures were excluded when being part of more complex procedures. A total of 876 procedures performed on 785 patients were left for examination. Complications were registered from the patient record and all received a written questionnaire or phone call. The answer was obtained from 97.6%. The overall complications rate was low, giving total of 5.00%. A total of 0.68% of the complications had therapeutic consequences. There were two superficial infections, one thromboembolic event/pulmonary embolus and one reoperation due to scar tissue. Other complications were considered minor, and had none or little consequence for the patient comprising preoperative bradycardial episodes, asthmatic events, subcutaneous infusion of total intravenous anaesthetics (TIVA), instrument breakage and conversion to arthrotomi. Postoperatively registered complications included swelling, haemarthros, portal bleeding and fistulation, temporary sensory loss and longstanding pain. Duration of surgery was the only predicting factor for postoperative complications. Simple arthroscopic surgery is safe and has few serious complications. The use of TIVA or tourniquet does not increase the morbidity or complication rate, and prophylaxis against thromboembolism was not necessary. PMID:16208459

    contrast, age, pain intensity, disability, and pain-associated psychological factors did not differ between pre-op PT treatment groups (P>0.05. Subacromial bursectomies were more commonly performed in patients having pre-op PT treatment (P<0.05. Pre-op PT treatment did not influence length of post-op PT treatment and did not affect 3-month and 6-month pain intensity and disability outcomes. Differences in distribution of pre-op PT for males and females and subacromial bursectomy did not influence 3-month or 6-month postsurgical outcomes. Conclusion: Receiving pre-op PT treatment did not influence post-op PT treatment or pain and disability outcomes at 3 months and 6 months. This prospective cohort study provides no evidence of benefit for pre-op PT on post-op PT treatment or postsurgical outcomes. Females or patients receiving certain surgical procedures are more likely to undergo pre-op PT treatment. However, these differences did not influence postoperative outcomes in this cohort.

    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.

    The International Society for Hip Arthroscopy (ISHA) Annual Scientific Meeting is at the forefront of informing today's orthopaedic surgeons and society of the rapid advances in the exponentially growing field of hip arthroscopy. The purpose of this study was to evaluate and observe any trends in the level of clinical evidence in the papers and posters presented at the ISHA Annual Scientific Meeting from 2010 to 2014. The online abstracts of the paper and poster presentations presented at the ISHA Annual Scientific Meetings were independently evaluated by two reviewers (582 total resulting presentations). Two reviewers screened these results for clinical studies and graded the quality of evidence from level I (i.e. randomized trials) to IV (i.e. case series) based on the American Academy of Orthopaedic Surgeons classification system. Four hundred and twenty-eight presentations met the inclusion criteria and were evaluated. Overall, 10.1% of the presentations were level I, 12.8% were level II, 30.1% were level III and 47.0% were level IV evidence. Over time, from 2010 to 2014, we observed an increase in the percentage of level II paper presentations, an increase in the proportion of level III poster presentations, and a decrease in the proportion of both level IV paper and poster presentations. Significant non-random improvement in the level of evidence presented was noted for the poster presentations (P = 0.012) but not for the paper presentations (P = 0.61) over the study period. Statistical trends demonstrate ISHA's increased awareness and commitment to presenting higher quality evidence as the availability of this evidence increases. PMID:27011857

    Full Text Available Abstract Background Ankle sprains are common in sports and can sometimes result in a persistent pain condition. Purpose Primarily to evaluate clinical symptoms, signs, diagnostics and outcomes of surgery for symptomatic chondral injuries of the talo crural joint in athletes. Secondly, in applicable cases, to evaluate the accuracy of MRI in detecting these injuries. Type of study: Prospective consecutive series. Methods Over around 4 years we studied 61 consecutive athletes with symptomatic chondral lesions to the talocrural joint causing persistent exertion ankle pain. Results 43% were professional full time athletes and 67% were semi-professional, elite or amateur athletes, main sports being soccer (49% and rugby (14%. The main subjective complaint was exertion ankle pain (93%. Effusion (75% and joint line tenderness on palpation (92% were the most common clinical findings. The duration from injury to arthroscopy for 58/61 cases was 7 months (5.7–7.9. 3/61 cases were referred within 3 weeks from injury. There were in total 75 cartilage lesions. Of these, 52 were located on the Talus dome, 17 on the medial malleolus and 6 on the Tibia plafond. Of the Talus dome injuries 18 were anteromedial, 14 anterolateral, 9 posteromedial, 3 posterolateral and 8 affecting mid talus. 50% were grade 4 lesions, 13.3% grade 3, 16.7% grade 2 and 20% grade 1. MRI had been performed pre operatively in 26/61 (39% and 59% of these had been interpreted as normal. Detection rate of cartilage lesions was only 19%, but subchondral oedema was present in 55%. At clinical follow up average 24 months after surgery (10–48 months, 73% were playing at pre-injury level. The average return to that level of sports after surgery was 16 weeks (3–32 weeks. However 43% still suffered minor symptoms. Conclusion Arthroscopy should be considered early when an athlete presents with exertion ankle pain, effusion and joint line tenderness on palpation after a previous sprain

    International Nuclear Information System (INIS)

    To evaluate the prevalence of deltoid ligament and distal tibiofibular syndesmosis injury on 3T magnetic resonance imaging (MRI) in patients with chronic lateral ankle instability (CLAI). Fifty patients (mean age, 35 years) who had undergone preoperative 3T MRI and surgical treatment for CLAI were enrolled. The prevalence of deltoid ligament and syndesmosis injury were assessed. The complexity of lateral collateral ligament complex (LCLC) injury was correlated with prevalence of deltoid or syndesmosis injuries. The diagnostic accuracy of ankle ligament imaging at 3T MRI was analyzed using arthroscopy as a reference standard. On MRI, deltoid ligament injury was identified in 18 (36%) patients as follows: superficial ligament alone, 9 (50%); deep ligament alone 2 (11%); and both ligaments 7 (39%). Syndesmosis abnormality was found in 21 (42%) patients as follows: anterior inferior tibiofibular ligament (AITFL) alone, 19 (90%); and AITFL and interosseous ligament, 2 (10%). There was no correlation between LCLC injury complexity and the prevalence of an accompanying deltoid or syndesmosis injury on both MRI and arthroscopic findings. MRI sensitivity and specificity for detection of deltoid ligament injury were 84% and 93.5%, and those for detection of syndesmosis injury were 91% and 100%, respectively. Deltoid ligament or syndesmosis injuries were common in patients undergoing surgery for CLAI, regardless of the LCLC injury complexity. 3T MRI is helpful for the detection of all types of ankle ligament injury. Therefore, careful interpretation of pre-operative MRI is essential

    Objective To investigate the clinical value of arthroscopy in the treatment of dorsal carpal ganglion. Methods A total of 22 cases of dorsal carpal ganglion was treated from September 2009 to May 2013.With 4/5 or 6R portal access as arthroscopy vision, 1/2 portal access as working pathway, and 6U for outflow, the scapholunate interosseous ligament ( SLIL) was found and then the examination was carried out toward dorsal part till the reentry point of SLIL and dorsal carpal articular capsule. Pedicles of dorsal carpal ganglion were exposed, and the pedicles and part of articular capsules were removed by planer tools.The joint fluid was cleaned till the ganglion disappeared.Then absorbable sutures were used to close subcutaneous tissues.Pressure bandaging was given.After the operation, a supporter was used to fix the wrist for 3 weeks, during which massage and restorative exercise were conducted. Results Conversion to open surgery was required in 2 cases because the pedicles of dorsal carpal ganglion were not found in intraoperative arthroscopic examinations, including the cyst originated in the extensor tendon in 1 case and originated in the mediocarpal joint in 1 case.The remaining 20 cases underwent treatment under arthroscopy successfully.The patients were followed up for 6-14 months, with an average of 9.2 months.The wrists were normal in appearance and fully functional without obvious scars. Three cases developed recurrence, 1 of which was not given further intervention because the cyst was too tiny to be found at neutral position, and 2 of which were given open resections. Conclusions Although arthroscopic treatment of dorsal carpal ganglion has a relatively high equipment and technical requirements and has certain limitations on indications, the surgery is safe with few complications and good appearance.It can be used as a treatment option for some young women with strong cosmetic requirements.%目的:探讨关节镜治疗腕背侧腱鞘

    Tibial plateau fractures belong to intra-articular fractures of the main weight-bearing joints of lower limbs. Traumatic osteoarthritis of the knee is mainly caused by articular surface collapse, joint deformities and joint instabilities after fractures. Therefore, the ideal target in the treatment of tibial plateau fractures is to obtain stable and painless knee joints with good counterpoint and alignment and normal range of motion, and to minimize the occurrence of traumatic osteoarthritis. In recent years, the widespread use of arthroscopic technique promotes the new progress in the diagnosis and treatment of tibial plateau fractures. In this article, the application of arthroscopy in the diagnosis and treatment of tibial plateau fractures was introduced, including the classiifcation of tibial plateau fractures, indications and contraindications of arthroscopic surgery, prevention and management of special problems of arthroscopic-assisted treatment of tibial plateau fractures and advantages and limitations of arthroscopic-assisted treatment of tibial plateau fractures versus traditional open reduction and internal ifxation. The progress of arthroscopy in the diagnosis and treatment of tibial plateau fractures was summed up, so as to provide reference for the clinical diagnosis and treatment of tibial plateau fractures.

    Objective: In literature the diagnostic value of MRI for detecting lesions of the carpal ligaments and the TFCC is judged controversially. The aim of the following study is to determine the diagnostic accuracy of direct MR arthrography for depicting and staging of intraarticular lesions of the wrist. Material and methods: One day before undergoing arthroscopy, 125 patients suffering from wrist pain were examined with direct MR arthrography in a prospective and blinded study. A mixture of contrast medium (iodine-containing contrast medium and gadopentetate in relation 200:1) was injected into both radiocarpal and midcarpal joints. The following sequences were acquired on a 1.5T scanner: coronal T1-weighted SE, coronal fat-saturated T1-weighted SE, coronal T1-/T2*-DESS-3D, and sagittal T2*-weighted MEDIC. MRI results were compared with arthroscopic findings using statistical analysis (SEN=sensitivity, SPE=specificity, PPV=positive predictive value, NPV=negative predictive value, ACC=accuracy). Results: In comparison to arthroscopy as the accepted diagnostic gold standard, the following results were found for MR arthrography. Detection of TFCC lesions: SEN 97.1%, SPE 96.4%, PPV 97.1%, NPV 96.4%, ACC 96.8%. Detection of complete tears of the scapholunate ligament: SEN 91.7%, SPE 100%, PPV 100%, NPV 99.1%, ACC 99.2%. Detection of partial tears: SEN 62.5%, SPE 100%, PPV 100%, NPV 94.8%, ACC 95.2%. Detection of cartilage defects: SEN 84.2%, SPE 96.2%, PPV 80%, NPV 97.1%, ACC 94.4%. In total, only three lesions of the lunotriquetral ligament were present. Conclusion: Direct MR arthrographic imaging is well suited for detecting intraarticular lesions of the wrist. The presented diagnostic results of MR arthrography are superior to the results of unenhanced MRI reported in the literature. Direct MR arthrography as a reliable diagnostic tool is strongly recommended if lesions of the scapholunate ligament and the triangular fibrocartilage complex are suspected. In contrast, an

    Background Nowadays, the wrist is not limited to a dorsal visualization; the joint can be thought of as a "box," which can be visualized from almost every perspective. The purpose of this study was to describe a new volar central portal for the wrist, following three principles: a single incision that allows access to both the radiocarpal and midcarpal joints, centered on the lunate, with the volar structures at risk protected not only by retractors, but also by tendons. Description of Technique The incision begins in the distal wrist crease and extended 1.5 cm proximally up to the proximal wrist crease, following the axis of the third intermetacarpal space. The flexor superficialis tendons are identified and retracted toward the radial side. Next, the fourth and fifth flexor digitorum profundus tendons are retracted toward the ulnar side, while the third and second tendons are retracted toward the radial side. The volar central midcarpal portal is performed under direct vision just over the anterior horn of the lunate through the Poirier space. The volar central radiocarpal portal is created under the lunate through the interval between the ulnocarpal ligaments and the short radioulnar ligament. Methods An anatomical study was performed on 14 cadaver specimens. Two data were recorded: iatrogenic injuries of the structures at risk and the distances to the structures at risk. Results The median (interquartile range [IQR]) distances from the volar central radiocarpal portal to the median nerve, palmar cutaneous branch of the median nerve, and ulnar neurovascular bundle were 10.5 (7.8-15.0), 18.5 (15.8-20.3), and 7.0 (5.0-10.5) mm, respectively. The median (IQR) distances from the volar central midcarpal portal to the median nerve, palmar cutaneous branch of the median nerve, and ulnar neurovascular bundle were 7.0 (4.8-10.3), 16.0 (14.8-19.0), and 4.5 (3.8-9.0) mm, respectively. No iatrogenic injuries were observed. Conclusion The volar central portal is reproducible and safe. The risk of iatrogenic injury is low. The capsule is pierced through one of its thinner portions, and both the radiocarpal and midcarpal joints can be inspected through one single incision. PMID:26855842

RESULTS: The use of CO2 for arthroscopy causes an acute and mild synovitis alike to the liquid capsular distension, showing similar synovial fluid increase of leukocytes, TP, and TNF-α. Although synovial fluid PGE2 content was higher in joints submitted to CO2 distension, lower levels of hemoglobin and leukocytes oxidative burst after surgery indicates that CO2 arthroscopy decreased intra-articular bleeding and activation of infiltrating leukocytes. CONCLUSIONS: The use of CO2 for arthroscopic examination causes acute and mild synovitis that is similar to the effects caused by the liquid capsular distension. CO2 also seems to decrease intra-articular bleeding and activation of leukocytes.OBJETIVO: Avaliar comparativamente a resposta inflamatória decorrente da distensão líquida ou gasosa em cavalos submetidos ao exame artroscópico. MÉTODOS: Cada animal foi submetido a uma artroscopia bilateral tarsocrural empregando uma distensão com gás em uma articulação e líquido na articulação contralateral. O líquido sinovial foi avaliado as zero, seis, 12, 24 e 48 horas do pós-operatório. RESULTADOS: A utilização de CO2 para a artroscopia provoca uma sinovite aguda e leve tal como a distensão capsular por líquido, mostrando um aumento similar de leucócitos, TP (proteína total e TNF-a. Embora no líquido sinovial a quantidade de PGE2 tenha sido maior nas articulações submetidas à distensão por CO2, níveis mais baixos de hemoglobina e explosão oxidativa de leucócitos após a cirurgia indica que a artroscopia com CO2 diminuiu o

    management of acute postoperative pain is becoming increasingly important for the progression of the patient during their hospital stay. Taking advantage of a change in the infrastructure of our complex, and being aware of the regular analgesic control required by certain patients, in this study we attempt to highlight the importance of this analgesic management being directed by the Anaesthetic Department. Material and methods: This study was performed in the Orthopaedic Surgical Unit of the Badajoz (Spain University Hospital Complex, lasted 2 months, and included two working groups consisting of Group A (arthroplasty with 33 patients and Group B (arthroscopy with 15 patients. We collected the relevant data for subsequent analysis (descriptive observational study, as well a survey carried out on the physicians of the Traumatology Unit and nursing staff, which collected a series of items to establish an opinion on the concepts to study. Results: Two fundamental deficiencies were found. Firstly, the levels of pain perceived by the patients were higher than those desired, and secondly, the analgesic techniques that were being practiced were not the most adequate and were not multimodal. Conclusions: According to the results we consider the support of the Anaesthetic Department as fundamental in the management of postoperative pain, since the final satisfaction of the patient would improve greatly. Although they were not objectives of the study, the days in hospital and the appearance of morbidity associated with the surgery would surely be reduced based on the existing literature. Furthermore, the surveys carried out showed a lack of protocols, clinical attitudes and training that the physicians and nurses demand.

    A ganglion cyst (GC) is a mucinous or gelatinous-filled benign tumor overlying a joint or tendon sheath, which commonly arises in the dorsal and volar wrist side but may occur anywhere in the body. Although cystic lesions around the knee are common, the occurrence of GCs are rare. Ganglia may arise from intra or extra-articular, soft tissue, intraosseous, or periosteal location. Symptoms may vary according to the size and location. After the more frequent performance of magnetic resonance imaging for the assessment of a knee joint, the number of incidental, asymptomatic lesions have been increasingly diagnosed. The etiology of GC remains unclear; however, trauma and a flaw in the joint tissues may explain its appearance. The authors report two cases of women aged 47 years and 37 years who presented pain and swelling in their left knees following arthroscopic partial medial meniscectomy. The former was surgically treated and had a favorable outcome, while the latter had conservative treatment and a gloomy outcome. PMID:26894048

  14. 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

    Seven consecutive patients undergoing arthroscopic surgery in a gravity-fed fluid delivery system were studied. The average minimum adequate intraarticular pressure (MAIP) was 55 mm Hg. The height of a saline bag above the knee necessary to achieve this average MAIP was 75 cm. There was a positive correlation between diastolic blood pressure and the minimum adequate intraarticular pressure in this study. There was no positive correlation between systolic blood pressure and the MAIP. PMID:1418206

    Background There is limited literature investigating preoperative physical therapy (pre-op PT) treatment on pain intensity and disability after musculoskeletal surgery. The purposes of the present cohort study were to describe patient characteristics for those who had and did not have pre-op PT treatment and determine whether pre-op PT influenced the length of postoperative physical therapy (post-op PT) treatment (number of sessions) and 3-month and 6-month postsurgical outcomes, such as pain intensity and disability. Patients and methods A total of 124 patients (mean age =43 years, 81 males) with shoulder pain were observed before and after shoulder arthroscopic surgery. Demographic data, medical history, and validated self-report questionnaires were collected preoperatively and at 3 months and 6 months after surgery. Analysis of variance models were performed to identify differences across measures for patients who had pre-op PT treatment and those who did not and to examine outcome differences at 3 months and 6 months. Alpha was set at the 0.05 level for statistical significance. Results Males had less participation in pre-op PT than females (P=0.01). In contrast, age, pain intensity, disability, and pain-associated psychological factors did not differ between pre-op PT treatment groups (P>0.05). Subacromial bursectomies were more commonly performed in patients having pre-op PT treatment (P<0.05). Pre-op PT treatment did not influence length of post-op PT treatment and did not affect 3-month and 6-month pain intensity and disability outcomes. Differences in distribution of pre-op PT for males and females and subacromial bursectomy did not influence 3-month or 6-month postsurgical outcomes. Conclusion Receiving pre-op PT treatment did not influence post-op PT treatment or pain and disability outcomes at 3 months and 6 months. This prospective cohort study provides no evidence of benefit for pre-op PT on post-op PT treatment or postsurgical outcomes. Females or patients receiving certain surgical procedures are more likely to undergo pre-op PT treatment. However, these differences did not influence postoperative outcomes in this cohort.

    2016-01-01

    Safe and effective arthroscopic surgery requires ambidextrous motor skills. The current study examined dominant versus non-dominant hand performance on a virtual reality serious game in a group of expert arthroscopic surgeons (n=15) compared to a group of orthopedic surgery residents (n=10). A virtual reality Tetris game was performed with the arthroscopic camera and arthroscope in one hand, using an arthroscopic grasping tool in the opposite hand to manipulate the virtual Tetris blocks onto the game grid. A second run was performed after swapping instruments between hands. The order of hand testing was randomized. There was no statistically significant difference in exercise time, grasper path length, or camera path length between the right and left hands of the expert surgeons. In contrast, there were statistically significant differences in all of these parameters between the two hands for the orthopedic surgery residents, with better performance when the grasping tool was used in the dominant hand. The findings of this study suggest that virtual reality games which incorporate progressive cognitive loading could be used to facilitate training, automation, and objective assessment of surgical motor skills.

    A total of 20 consecutive patients with knee stiffness post total knee arthroplasty (TKA) underwent arthroscopic lysis of adhesions and manipulation plus indwelling epidural were evaluated retrospectively. Epidural catheters were placed preoperatively for an intended 6 weeks of postoperative analgesia to facilitate intensive physical therapy. The mean loss of knee extension immediately before incision was 13.5 ± 9.1 degrees (range, 0-35 degrees) and flexion was 77.65 ± 19.2 degrees (range, 45-125 degrees). At the 6-week and final (mean, 0.47 years) follow-up, the loss of extension was 1.5 ± 5.1 degrees (range, -10 to +7 degrees) and 5.4 ± 4.7 degrees (range, 0-15 degrees), respectively, and flexion was 99.7 ± 12.3 degrees (range, 75-120 degrees) and 98.5 ± 16.1 degrees (range, 75-130 degrees), respectively. Of the 20 patients, 2 missed their 6-week clinic visit. Improvements in motion immediately preoperative to 6-week and final follow-up were each significant (p definition for clinical motion success and 70% maintained success at final follow-up. Visual analog scale improved significantly from 5.4 to 2.0 (p success postoperatively as measured by range of motion improvement. PMID:25300008

    2003-12-01

    Full Text Available Introduction: Artroscopy of the knee is a procedure that is frequently developed as a diagnostic and therapeutic means in patients who suffer among other diseases, from chronic sinuvitis, lesions of the meniscus and adherence . A great number of these patients receive medical assistance at the outpatient department of the orthopaedic department where the need of its use is assessed. It is a relatively short procedure that has few risks when it is performed with the appropriate technique. Objective: To show the use of intra articular Bupivacaine 0,25 % in the artroscopy of the knee. Method: Retrospective study carried out at the University Hospital ¨Dr. Gustavo Aldereguía Lima¨ from Cienfuegos province from September 2002 to February 2003. This study was developed with 20 patients who were initially assisted at the service of Orthopaedics in which a group of therapeutic procedures were decided. Bupivacaine 0,25 % together with Epinephrine 0,1 % in a dose of 0,1 ml were injected in the intra articular space in a volume of 20 ml distributed in 4 sections with 5 ml each. At the level of the section where the artroscope was inserted , 5 ml of Bupivacaine 0,25 % was applied Result: the age of the patient ranged 30 to 61 years of age with a media of 44,6 years and a standard deviation of 12,6 years. The introduction and application of the procedure throughout artroscopy was possible in al patients. Conclusion: Bupivacaine is a good local anaesthetic because of its slow action since the onset of application and its prolonged duration, and because of the intensity and the duration of the sensorial block that is superior to the motor block.
    Introducción: La artroscopia de la rodilla es un proceder que se realiza frecuentemente en la actualidad con fines diagnósticos y terapéuticos, a pacientes portadores de enfermedades como sinovitis crónica, lesiones de menisco, adherencias, entre otros. Un considerable número de estos pacientes son atendidos en consulta de ortopedia, donde se valora la necesidad o no de su realización. Es un proceder relativamente corto y con pocos riesgos cuando se realiza con la técnica adecuada. Objetivo : Demostrar el uso de la bupivacaína al 0,25 % intraarticular en la artroscopia de la rodilla. Métodos: Estudio prospectivo realizado en el Hospital ¨Dr. Gustavo Aldereguía Lima¨ de Cienfuegos en el período comprendido entre septiembre 02 y febrero del 03 a un grupo de 20 pacientes atendidos inicialmente por el Servicio de Ortopedia y luego por Anestesiología, decidiéndose en conjunto el proceder terapéutico. Se inyectó bupivacaína en el espacio intraarticular, a 0,25 % con epinefrina 0,1 ml al 0,1 %, en un volumen de 20 ml, distribuidos en 4 portales a razón de 5 ml en cada uno. A nivel del portal donde se introdujo el artroscopio, se aplicó 5 mil. de bupivacaína al 0,25 % Resultados: Las edades de los pacientes oscilaron entre 30 y 61 años con una media de 44,6 años y desviación estándar de 12.6 años. Fue posible la introducción y la realización de los procedimientos a través de la artroscopia en todos los pacientes. Conclusión : La bupivacaína resultó un agente anestésico local muy favorecedor, por su inicio de acción lento y una duración prolongada, la intensidad y duración del bloqueo sensorial superior a las del bloqueo motor.

    A prospective study was performed on 50 patients suffering from osteochondritis dissecans of the knee and ankle to define criteria for stability and fixation of osteochondral lesions. Morphological parameters in MRI (size, fragmentation, cartilage, interface) and conventional radiology (separation, fragmentation) were registered and compared with arthroscopical staging. MRI staging based on different types of interfaces was demonstrated on T{sub 1}- and T{sub 2}-weighted images. MRI could correctly predict a Grade 1 lesion in 50%, a Grade 2 lesion in 90%, a Grade 3 lesion on 0%, and a Grade 4 lesion in 79%. Stable lesions were differentiated from unstable lesions in 90%. Radiographic findings corresponded with arthroscopic staging in only 56% of the cases because fibrotic connection may guarantee stability in case of bony separation. (orig./MG) [Deutsch] In einer prospektiven Studie an 50 Patienten mit einer Osteochondrosis dissecans (OD) des Knie- und Sprunggelenkes sollten MRT-Kriterien zur Beurteilung der Stabilitaet bzw. Einbindung des osteochondralen Fragmentes bestimmt werden. Fuer jede Laesion wurden verschiedene morphologische Merkmale im MRT (Groesse, Sinterung, Vitalitaet, Knorpelbeschaffenheit, Grenzzone) und im konventionellen Roentgenbild (Separation, Sinterung) bestimmt und mit den entsprechenden arthroskopischen Stadien verglichen. Das MRT-Stadium wurde anhand der Morphologie der Grenzzone der OD im T{sub 1}- und T{sub 2}-gewichteten Bild definiert. Mit der MRT wurde das Stadium 1 in 50%, das Stadium 2 in 90%, das Stadium 3 in 0% und das Stadium 4 in 79% richtig vorhergesagt. Eine korrekte Einstufung in stabile und instabile Fragmente gelang in 90% der Faelle. Mit der konventionellen Radiologie war eine Uebereinstimmung mit den arthroskopischen Stadien nur in 56% zu erreichen, da auch nativradiologisch abgetrennt erscheinende Fragmente noch stabil mit dem Mausbett verbunden sein koennen.

  19. Articular cartilage damage with intramedullary lesion (bone bruise) in anterior cruciate ligament rupture

    International Nuclear Information System (INIS)

    We evaluated the relationship between the intramedullary lesion on MRI and cartilage damage in patients associated with acute anterior cruciate ligament (ACL) rupture. Thirty-two cases documented by MRI and arthroscopy within one month from injury underwent ACL reconstruction using ST-G, and arthroscopy was performed again after surgery. The mean term between reconstruction and postoperative arthroscopy was twelve months. The cartilage damage on arthroscopy was compared with the intramedullary lesion on MRI. Cartilage damage was observed in 9 cases (28.1%) during the initial arthroscopy and in 16 cases (50.0%) during the second arthroscopy. Intramedullary lesion was detected in all 32 cases (total: 73 lesions) on MRI. Intramedullary lesion leading to cartilage damage was common in the geographic-type lateral femoral condyle. There was significant difference between the lateral meniscus tear and the cartilage damage of the lateral compartment. (author)

    Full Text Available The role of hip arthroscopy in the management of femoroacetabular impingement (FAI has been advancing rapidly. In this case report, we describe the use of hip arthroscopy to successfully treat a femoral neck osteochondroma that caused a symptomatic labral tear in a 37 year old woman. Hip arthroscopy offers several advantages to surgical dislocation of the hip in the management of intra articular pathology and FAI. Hip arthroscopy is minimally invasive without the significant trauma to hip musculature, is useful in treatment of labral tears generated by FAI, and can be used to resect small lesions on the femoral head.

Os pacientes incluídos no estudo tiveram seu índice de massa corporal (IMC aferido e foram classificados entre os diferentes graus de obesidade. Foram aferidas a dobra cutânea abdominal e a tricipital contralateral com um adipômetro graduado em milímetros, bem como determinado o biótipo de cada indivíduo através do ângulo mensurado no apêndice xifóide. A tenotomia do CLB, quando indicada, foi realizada junto a sua inserção no labrum superior da glenóide. Os pacientes foram questionados quanto à percepção da deformidade residual gerada pela tenotomia do CLB. As variáveis estudadas foram: idade, sexo, lado operado, dominância, biótipo, grau de obesidade, dobra cutânea abdominal e dobra cutânea tricipital contralateral. Foram avaliados 77 pacientes com média de 15,14 (± 10,7 meses de pós-operatório. RESULTADOS: Não houve queixa da deformidade em 50 (64,9%, enquanto 27 pacientes (35,1% manifestaram alguma queixa estética. A análise estatística não foi significativa quando avaliou de forma cruzada a idade (p = 0,788, o lado (p = 0,075 e o biótipo (p = 0,529 dos pacientes que apresentaram queixa estética de sua deformidade residual. Houve correlação significativa para a queixa da deformidade quando foram avaliados o sexo (p = 0,004, a dominância (p = 0,026 e ao agrupar os pacientes com IMC abaixo de 30 (normal e sobrepeso e compará-los com os pacientes com IMC acima de 30 (obesidade graus 1, 2 e mórbida (p = 0,005. Demonstrou-se correlação significativa para a queixa da deformidade nos pacientes com a dobra cutânea abdominal abaixo de 23,2mm (p = 0,003, bem como com a dobra cutânea tricipital contralateral abaixo de 14,5mm (p = 0,001. CONCLUSÕES: A freqüência da queixa estética foi de 35,1% na amostra. Pacientes masculinos; submetidos à tenotomia do CLB no lado dominante; com IMC abaixo de 30; com dobra cutânea abdominal abaixo de 23,2mm e dobra cutânea tricipital contralateral abaixo de 14,5mm são considerados de risco para apresentar queixa estética da deformidade residual.OBJECTIVE: To analyze the frequency of esthetic complaints after tenotomy of the long head of the biceps in order to create a criterion for some pre-operative analysis that could identify patients that tend to complain about esthetics after the procedure, and thus reduce the incidence. METHODS: A group of 89 patients (90 shoulders submitted to arthroscopic tenotomy of the long head of the biceps was analyzed. Patients included in the study had their bodily mass index (BMI measured and were classified into different degrees of obesity. The abdominal skin fold and the contralateral tricipital skin fold were measured with a millimeter-graded adipometer, and the biotype of each individual was determined by the angle measured in the xiphoid appendix. Tenotomy of the long head of the biceps, when indicated, was performed at its insertion in the upper labrum of the glenoid. Patients were asked about their perception of residual deformity created by the tenotomy of the long head of the biceps. Variables studied were age, gender, operated side, dominance, biotype, degree of obesity, abdominal skin fold, and contralateral tricipital skin fold. 77 patients were evaluated for a mean 15.14 (± 10.7 months period after the surgery. RESULTS: 50 patients (64.9% did not complain about deformity, whereas 27 patients (35.1% had some esthetic complaint. Statistical analysis was not significant in the cross analysis for age (P = 0.788, the side (P = 0.075, and the biotype (P = 0.529 of the patients who did present an esthetic complaint about their residual deformity. Significant correlation of deformity complaint was present in the evaluation of gender (p = 0.004, dominance (P = 0.026, and when a group was formed of patients with BMI below 30 (normal and overweight and this group was compared to patients with BMI above 30 (obesity grade one, two, and morbid (P = 0.005. A significant correlation was shown for the deformity complaint in patients with abdominal skin fold of less than 23.2 mm (P = 0.003, and with the contralateral tricipital skin fold of less than 14.5 mm (p = 0.001. CONCLUSIONS: The frequency of esthetic complaint was of 35.1% in the series. Male patients; submitted to tenotomy of the long head of the biceps on the dominant side, with BMI below 30; with abdominal skin fold of less than 23.2 mm and contralateral tricipital skin fold of less than 14.5 mm are considered at risk of presenting some esthetic complaint regarding residual deformity.

    背景:随着外科技术、重建材料技术的发展,关节置换在肩关节脱位中也得到了广泛应用,特别是各种定制型或装配型假体使得置换适应证明显提高。  目的:观察与随访关节镜与关节置换治疗肩关节复发性前脱位伴重度骨缺损的远期疗效。  方法:纳入肩关节复发性前脱位伴重度骨缺损患者144例,根据随机抽签分为治疗组与对照组,每组72例。对照组行关节镜下内固定治疗,治疗组行关节置换治疗。通过电话调查与复诊完成3年随访,记录患者Neer肩关节功能评分、肩关节活动度及并发症发生情况。  结果与结论:随访3年,治疗组的肩关节功能优良率90%明显高于对照组81%(P RESULTS AND CONCLUSION:After 3-year fol owed-up, the excel ent and good rate of shoulder function was significantly higher in the treatment group (90%) than in the control group (81%) (P<0.05). The magnitude of the flexion in the 3-year fol owed-up was apparently increased, while the lateral margin external rotation was decreased, which showed significant differences after intragroup comparison (P<0.05). Simultaneously, the magnitude of the flexion and the lateral margin external rotation in the treatment group had statistical y significant differences compared to the control group in the 3-year fol owed-up (P<0.05). The complications of wound infection, shoulder dislocation, and implant loosening in the treatment group during fol ow-up were significantly lower than in the control group (P<0.05). These findings verified that compared with arthroscopic surgery, arthroplasty for treating recurrent anterior dislocation of the shoulder joint with severe bone defects in long-term fol ow-up can effectively restore shoulder function and range of motion, and it has few complications, thereby effectively rebuilds shoulder joint.

  5. Tibialis Posterior Tendon Entrapment Within Posterior Malleolar Fracture Fragment.

    Science.gov (United States)

    Fantry, Amanda; Lareau, Craig; Vopat, Bryan; Blankenhorn, Brad

    2016-01-01

    Management of posterior malleolus fractures continues to be controversial, with respect to both need for fixation and fixation methods. Fixation methods include an open posterior approach to the ankle as well as percutaneous reduction and fixation with or without arthroscopy for visualization of the articular surface. Plain radiographs are unreliable in identifying fracture pattern and intraoperative reduction, making arthroscopy a valuable adjunct to posterior malleolus fracture management. In this article, we report a case of tibialis posterior tendon entrapment within a posterior malleolus fracture, as identified by arthroscopy and managed with open reduction. Tibialis posterior tendon entrapment within a posterior malleolus has not been previously reported. Ankle arthroscopy for posterior malleolus fractures provides an opportunity to identify soft-tissue or tendinous entrapment, articular surface reduction, and articular cartilage injuries unlikely to be identified with fluoroscopy alone and should be considered in reduction and fixation of posterior malleolus fractures.

  13. Degenerative joint disease on MRI and physical activity: a clinical study of the knee joint in 320 patients

    International Nuclear Information System (INIS)

    We examined 320 patients with MRI and arthroscopy after an acute trauma to evaluate MRI in diagnosis of degenerative joint disease of the knee in relation to sports activity and clinical data. Lesions of cartilage and menisci on MRI were registered by two radiologists in consensus without knowledge of arthroscopy. Arthroscopy demonstrated grade-1 to grade-4 lesions of cartilage on 729 of 1920 joint surfaces of 320 knees, and MRI diagnosed 14 % of grade-1, 32 % of grade-2, 94 % of grade-3, and 100 % of grade-4 lesions. Arthroscopy explored 1280 meniscal areas and showed degenerations in 10 %, tears in 11.4 %, and complex lesions in 9.2 %. Magnetic resonance imaging was in agreement with arthroscopy in 81 % showing more degenerations but less tears of menisci than arthroscopy. Using a global system for grading the total damage of the knee joint into none, mild, moderate, or severe changes, agreement between arthroscopy and MRI was found in 82 %. Magnetic resonance imaging and arthroscopy showed coherently that degree of degenerative joint changes was significantly correlated to patient age or previous knee trauma. Patients over 40 years had moderate to severe changes on MRI in 45 % and patients under 30 years in only 22 %. Knee joints with a history of trauma without complete structural or functional reconstitution showed marked changes on MRI in 57 %, whereas stable joints without such alterations had degenerative changes in only 26 %. There was no correlation of degenerative disease to gender, weight, type, frequency, and intensity of sports activity. Therefore, MRI is an effective non-invasive imaging method for exact localization and quantification of chronic joint changes of cartilage and menisci that recommends MRI for monitoring in sports medicine.

    We report a case of inferior lateral genicular artery (ILG) injury during anterior cruciate ligament (ACL) reconstruction surgery with lateral partial meniscectomy. This is a rare arthroscopy complication. A review of the literature has been made with the aim to define the anatomy of ILG across the lateral articular line and the risk of lesion during knee arthroscopy. We propose embolization as a good treatment option for this type of injuries.

    Intra-articular fractures may result in stiffness, deformity, pain and post-traumatic arthritis. In order to avoid deformity and stiffness, it is necessary to secure an anatomical reduction and early motion. Recently arthroscopy is being used to treat more complex pathologies such as intra-articular fractures of the knee joint. The main advantages of this procedure are improved visualization and decreased patient morbidity. Additionally arthroscopy allows the orthopedic surgeon to assess and ...

  1. MRI profiles of menisci of the knee

    International Nuclear Information System (INIS)

    The rate of correct diagnosis of disorders of menisci is considered to exceed 95% by arthrography and arthroscopy, but these examinations are both invasive and effective only for evaluation of changes on the surface of meniscus. Diagnosis of injury of the posterior horn of the lateral meniscus is difficult by athrography, and that of injury of the posterior horn of the medial meniscus is difficult by arthroscopy. MRI is a non-invasive examination that allows the diagnosis of changes of the surface and the inside of the meniscus. This study reviewed 44 cases in which MRI findings could be confirmed by arthroscopy or at operating among 114 patients who underwent MRI to rule out the possibility of meniscus injury during the period between August 1988 and June 1991. The total number of patients who underwent MRI during this period was 6,983. The apparatus used was a 1.5-Tesla superconductive MR system, and evaluation was based mainly on the control T1-weighted image obtained by the spin-echo mode and sagittal image double-echo sequence. Characteristics of MRI were described as follows. Four cases of injury of the medial meniscus are (1) typical bucket-handle injury; (2) horizontal tear visible by arthroscopy; (3) horizontal tear difficult to observe by arthroscopy; (4) horizontal tear after partial meniscectomy under arthroscopy. Four cases of injury of the lateral meniscus are (1) multiple tear and artifact of foreign body of needle-fragment; (2) longitudinal tear; (3) multiple injury of discoid meniscus; (4) locking of discoid meniscus. MRI was considered to be advantageous over arthrography or arthroscopy in injury of medial meniscus (especially horizonal tear extending to the lower surface on the tibial side), meniscus ganglion, injury of the posterior horn of the lateral meniscus, and discoid menisci of children. From the findings in these 44 cases, MRI is considered to provide important information for the diagnosis of injury of menisci. (author)

    Purpose: To evaluate the diagnostic efficacy of using additional oblique coronal 1 mm proton density-weighted (PDW) MR imaging of the knee for detection and grading anterior cruciate ligament (ACL), anteromedial bundle (AMB) and posterolateral bundle (PLB) injuries. Materials and methods: We prospectively assessed preoperative MR images of 50 patients (36 men, 14 women; age range, 18–62 years). First, we compared the diagnostic performance of routine sagittal (3 mm) and additional oblique coronal images (1 mm) for ACL tears. Then, we compared the tear types (AMB or PLB) and grade presumed from oblique coronal MR imaging with arthroscopy. Results: Arthroscopy revealed ACL tear in 24 (48%) patients. There was significant difference between sagittal images and arthroscopy results for ACL tear recognition (p < 0.001). No significant difference was detected for oblique coronal images when compared with arthroscopy results (p = 0.180). Sensitivity and specificity values for ACL tear diagnosis were 37.04% and 95.65% for sagittal images; 74.07% and 91.30% for oblique coronal images. There was no significant difference between arthroscopy and oblique coronal MR images in grading AMB and PLB injuries (p > 0.05). Conclusion: Addition of thin slice oblique coronal images to conventional sequences could better contribute to better verifying the presence of ACL tear and in determining its grade.

    We incidentally noted distinctive high signal defects or fissures in the patellar articular cartilage on sagittal T2-weighted magnetic resonance (MR) images in 4 patients. At subsequent arthroscopy all 4 patients were found to have patellar chondromalacia. To determine the reliabilty of these signs, we retrospectively evaluated, in a blinded manner, sagittal T2-weighted MR images of the knee in 75 patients who were undergoing arthroscopic assessment of their patellar articular cartilage. We indentified high signal defects of fissures in the patellar cartilage of 5 patients. Patellar chondromalacia was noted at arthroscopy in all 5 patients. Arthroscopy demonstrated patellar chondromalacia in an additional 21 patients with normal MR images. We conclude that high signal defects or fissures on sagittal T2-weighted images are usefull signs of patellar chondromalacia. This single imaging sequence will, however, detect only a small number of the cartilage lesions that may be present. (orig.).

    Recent advances in hip arthroscopy offer an approach for treating an uncommon but highly disabling injury from intra-articular missile injury to the hip. Hip arthroscopy affords the patient the benefit of minimally invasive surgery while allowing for the diagnosis and treatment of concomitant pathology, which may be either acute, from the trauma of the missile, or chronic. We present a technique for the removal of projectiles from the central and peripheral compartments of the hip joint. Through a surgical series of a variety of gunshot wounds, we detail the unique aspects of retrieval for the various missile endpoints. We describe this technique for bullets or pieces of bullets lodged within the hip joint space, bone of the acetabulum, or femoral head. Furthermore, we provide an example in which hip arthroscopy is not a suitable option for treatment because of the resulting fracture pattern, which necessitates open reduction along with internal fixation.

    Surgery for femoroacetabular impingement (FAI) has been advocated for correction of cam and pincer hip joint morphology. Surgery for FAI was first pioneered by Myers et al, who surgically treated FAI by open dislocation. Arthroscopy was then introduced in 2005 by Sampson. Arthroscopy has continued to develop since then, with the intent of providing pain relief and improving function in patients with FAI. This Viewpoint discusses the escalating popularity of FAI surgery, the widespread acceptance of this relatively new surgical procedure, and next steps for determination of who benefits from this treatment.

  11. Magnetic resonance imaging of meniscal and anterior cruciate ligament injuries of the knee

    International Nuclear Information System (INIS)

    To categorise discrepancies in findings of the menisci and anterior cruciate ligament (ACL) between arthroscopy and MRI. Materials and methods: The MRIs of 236 patients were retrospectively analysed by an experienced radiologist without knowledge of clinical and/for operative findings. Discrepancies in arthroscopic findings were reevaluated together with the arthroscopist to determine their cause of error. Results: The diagnostic accuracies for injuries of the medial and lateral meniscus and the ACL were 92.4%, 92.4%, and 94.1%. respectively. For the menisci, causes for discrepancies in findings (n=31) were: overinterpretation of central signal intensities with contact to the meniscal surface but without disturbance of the meniscal contour as a tear (n=12), insufficient arthroscopie evaluation of the knee joint (n=11), overlooked tears on MR imaging (n=6), misinterpretation of normal anatomic structures (n=1), ''magic angle'' phenomenon (n=1), and missed tears at MRI (n=1). Causes for discrepancies for the ACL (n=18) were: nearly complete versus complete rupture either at MRI or arthroscopy and vice versa (n=9), insufficient arthroscopic evaluation (n=6), insufficient MRI technique (n=2), and overlooked tear on MR imaging (n=1). Conclusions: Discrepant findings between MRI and arthroscopy may be also due to an insufficient arthroscopic evaluation in clinical routine. The close cooperation between surgeons and radiologists improves the understanding of the methods of each other. (orig.)

  14. The value of water-excitation 3D FLASH and fat-saturated PDw TSE MR imaging for detecting and grading articular cartilage lesions of the knee

    International Nuclear Information System (INIS)

    To evaluate the diagnostic accuracy of water-excitation (WE) 3D FLASH and fat-saturated (FS) proton density-weighted (PDw) TSE MR imaging for detecting, grading, and sizing articular cartilage lesions of the knee. A total of 26 patients underwent MR imaging prior to arthroscopy with the following sequences: (1) WE 3D FLASH: 28/11 ms, scan time: 4 min 58 s, flip angle: 40 ; (2) FS PDw TSE: 3433/15 ms, scan time: 6 min 15 s, flip angle: 180 . Grade and size of the detected lesions were quantified and compared with the results of arthroscopy for each compartment. The sensitivity, specificity, positive and negative predictive values, and accuracy for detecting cartilage lesions were 46%, 92%, 81%, 71% and 74% for WE 3D FLASH and 91%, 98%, 96%, 94% and 95% for FS PDw TSE MR imaging. WE 3D FLASH correlated significantly with arthroscopy for grading on the patella (P<0.0001) and the femoral trochlea (P=0.02) and for sizing on the femoral trochlea (P=0.03). FS PDw correlated significantly (P<0.0001) with arthroscopy for grading and sizing on all compartments. FS PDw TSE is an accurate method for detecting, grading and sizing articular cartilage lesions of the knee and yielded superior results relative to WE 3D FLASH MR imaging. (orig.)

    The purpose of this study was to assess the usefulness of MRI in the evaluation of autografts after anterior cruciate ligament reconstruction. The subjects were 110 patients with anterior cruciate ligament reconstruction using patellar tendon autografts who underwent clinical examination, MRI, and arthroscopy of the knee. T1- and T2-weighted MR images were obtained in sagittal plane. Clinical findings were categorized into three groups: normal, borderline, and abnormal. The MRI appearances of the autografts were categorized into three types: straight continuous band (type I), interrupted band (type II) and generalized increased intensity band (type III). The clinical findings and MRI findings were compared with arthroscopic findings. Ninety-six percent of the type I showed no autograft tear on arthroscopy. In comparison with the clinical findings, MRI was found to be well correlated with arthroscopic findings. In conclusion, if the clinical findings are normal, patients are to be followed-up without MRI and arthroscopy. However, if clinical findings are either borderline or abnormal, MRI should be performed prior to arthroscopy. (author)

    To investigate the accuracy of conventional magnetic resonance imaging (MRI) in determining the severity of glenoid bone loss in patients with anterior shoulder dislocation by comparing the results with arthroscopic measurements. Institutional review board approval and written consent from all patients were obtained. Thirty-six consecutive patients (29 men, seven women; mean age, 34.5 [range, 18-55] years) with recurrent anterior shoulder dislocation (≥3 dislocations; mean, 37.9; range, 3-200) and suspected glenoid bone loss underwent shoulder MRI before arthroscopy (mean interval, 28.5 [range, 9-73] days). Assessments of glenoid bone loss by MRI (using the best-fit circle area method) and arthroscopy were compared. Inter- and intrareader reproducibility of MRI-derived measurements was evaluated using arthroscopy as a comparative standard. Glenoid bone loss was evident on MRI and during arthroscopy in all patients. Inter- and intrareader correlations of MRI-derived measurements were excellent (intraclass correlation coefficient = 0.80-0.82; r = 0.81-0.86). The first and second observers' measurements showed strong (r = 0.76) and moderate (r = 0.69) interreader correlation, respectively, with arthroscopic measurements. Conventional MRI can be used to measure glenoid bone loss, particularly when employed by an experienced musculoskeletal radiologist. (orig.)

  9. Accuracy of 3-Tesla MR and MR arthrography in diagnosis of meniscal retear in the post-operative knee

    International Nuclear Information System (INIS)

    This study assesses the accuracy of 3-Tesla (3-T) conventional MR imaging, 3-T MR arthrography, and the combined use of conventional MR and MR arthrography in the diagnosis of meniscal retears as compared with arthroscopy. The study also assess whether there are false-negative cases in which injected contrast does not extend into the meniscus despite a meniscal retear being seen on arthroscopy. One hundred consecutive knee MR arthrograms performed on patients with previous knee surgery were reviewed retrospectively. 3-T conventional MR imaging, 3-T MR arthrography, and the combined use of conventional MR and MR arthrography were assessed for meniscal retears as compared with arthroscopy. The criterion used to diagnose a meniscal retear on MR arthrogram was injected contrast tracking into the meniscus. All patients underwent second-look arthroscopy. Seventy-four patients had conventional MR findings consistent with a meniscal retear. In 83 of the 100 patients, intraarticular contrast helped in demonstrating a retear. In ten patients, there were MR findings consistent with a meniscal retear despite intra-articular contrast not tracking into the meniscus. Ninety-four of the 100 patients had meniscal retears on second-look arthroscopy. Three-Tesla conventional MR examination was 78 % sensitive and 75 % specific, MR arthrogram examination was 88 % sensitive and 100 % specific, and the combined use of MR and MR arthrogram imaging was 98 % sensitive and 75 % specific in the diagnosis of a meniscal retear. The combined use of 3-T MR and MR arthrography allows for high sensitivity and specificity in meniscal retear detection. In some patients, intraarticular contrast will not track into a meniscal retear. When MR findings are consistent with a meniscal retear but contrast does not extend into the meniscus, a meniscal retear is likely. (orig.)

    Full Text Available Objective:This study is analyzing the role and significance of the three diagnostic methods (clinical diagnosis, magnetic resonance imaging (MRI and arthroscopy, in establishing accurate diagnosis in knee injuries. The goal is to determine the diagnostic accuracy of each diagnostic method, using arthroscopy as gold standard. Material and Methods: We examined 70 patients with knee injuries. Clinical diagnosis was established using patient’s history and positive clinical tests for meniscal lesions, ACL injury and articular cartilage lesions. All patients underwent MRI on a 1.5 T magnet for MRI diagnosis. This was followed by arthroscopy for making the final diagnosis. Results: We analyzed the results of clinical tests for meniscal, ligamentous and articular cartilage injuries of the patients in both groups. Validity of the clinical tests was compared to the results got from MRI and arthroscopy. Accuracy of clinical diagnosis versus MRI diagnosis for medial(69.6% vs. 68.5% and lateral (84% vs. 82.6%meniscal lesions was almost identical. Accuracy of clinical diagnosis compared with the accuracy of MRI diagnosis for ACL injuries was higher (91.3% vs. 81.4%. Accuracy (85.5% vs. 72.8% of clinical diagnosis versus MRI diagnosis for articular cartilage lesions was better. Conclusion: Affirmation of clinical diagnosis in this study is a result of usage of standard clinical signs and tests which are fundamental in establishing clinical diagnosis of knee injuries. MRI is a diagnostic method which enriches the diagnostic process. Arthroscopy is defined as superior diagnostic method, also a gold standard for comparison of the other two diagnostic methods.

  12. Initial clinical experience of MRI microscopy coil to triangular fibrocartilage complex

    International Nuclear Information System (INIS)

    This paper presents the efficacy of high-resolution MRI using a microscopy coil at 1.5 T for diagnosing triangular fibrocartilage complex (TFCC) injury, compared with arthroscopy and arthrography. All subjects were imaged in the prone position with the arm over the head. The wrist was kept in the pronation position and a microscopy coil was placed on the center of ulnar head. All MR images were obtained at 1.5 T. Two-dimensional gradient-echo (GRE), short tau inversion recovery (STIR) and fast spin echo (FSE) images of the wrist were acquired using a microscopy coil (47 mm in diameter). Eight patients with injured TFCC were studied with both arthrography and MRI, and three patients were studied with both arthroscopy and MRI. The structures of TFCC were classified into 6 regions (radius attachment, disc proper, triangular ligament, lunate-triquetral attachment, volar side radio-ulnar ligament, and dorsal side radio-ulnar ligament), and were evaluated by one orthopedics surgeon and two radiologists. It was possible to distinguish each structure of the TFCC using high-resolution MRI with a microscopy coil. The injuries were pointed out at radius attachment in 3 patients, disc proper in 4, triangular ligament in 4, dorsal side radio-ulnar ligament in 3, volar side radioulnar ligament in 7, and lunate-triquetral attachment in 7 on MRI. Using arthroscopy, injuries at lunate-triquetral attachment in 1, dorsal side radio-ulnar ligament, and triangular ligament in 3 were not observed possibly because of dorsal approach. Another TFCC injuries on MRI in 3 patients were consistent with those with arthroscopy. High-resolution MRI with a microscopy coil allowed to describe most of TFCC injuries, and to evaluate triangular ligament, lunate-triquetral attachment and dorsal side radio-ulnar ligament, which could not be observed by arthroscopy and arthrography.

  14. Imaging of postarthroscopic complications after knee injuries

    International Nuclear Information System (INIS)

    The most common joint injuries in professional and recreational sports participants and also in the total population are knee injuries. Arthroscopy is indicated if this modality will improve the patient outcome and potential long-term complications can be avoided. Although uncommon, complications following arthroscopy are mostly evaluated by magnetic resonance imaging (MRI). For planning further therapy strategies following postarthroscopic complications, e.g. if anterior cruciate ligament (ACL) reconstruction is required, digital radiographs and computed tomography (CT) are helpful. This article provides an overview of the different procedures for surgical treatment which are a prerequisite for the analysis of postarthroscopic images. In addition typical complications after treatment of meniscal and chondral injuries as well as after ACL reconstruction are described and typical signs in MRI, radiography and CT are explained in detail.

  15. Radiographer led supplementary anterior cruciate ligament MRI sequences: Technical report

    International Nuclear Information System (INIS)

    Aims: To compare different supplementary MRI sequences of the ACL to arthroscopy and determine the diagnostic performance of each sequence. To ascertain whether radiographers could identify patients requiring supplementary MRI sequences of anterior cruciate ligament (ACL) tears, without a supervising radiologist. Methods: The study had ethical approval and two hundred and thirty one consecutive prospective MRI patients with mechanical knee symptoms (77 females, 154 males, of mean age 43.5, range 18–82 years) gave written informed consent. They then had a knee arthroscopy within seven days of the MRI. This was a pragmatic study to see if the six general MRI radiographers, each with over four years experience, could evaluate the ACL on routine orthogonal sequences (sagittal T1, Gradient Echo T2, Coronal STIR and axial fat suppressed dual echo). If they identified no ACL, then two 3D volume sequences (Dual Echo Steady State and Fast Low Angle Shot) and 2D limited sagittal oblique T1 sequences were also performed. Patients requiring extra sequences, missed by the radiographers, were recalled. The MRI sequences were independently evaluated in a blinded fashion by two consultant radiologists and a specialist radiology registrar and compared to the subsequent knee arthroscopy, as the gold standard, to determine the diagnostic performance statistics. Results: The cohort was on the knee arthroscopy weighting list and comprised 205 patients with chronic, 20 acute and 6 acute on chronic mechanical knee symptoms. There were no posterior cruciate, medial, or lateral collateral ligament tears at arthroscopy, used as the gold standard. The arthroscopy was normal and the radiographers correctly did not scan the extra sequence in 140 patients (72%) who then had normal arthroscopies. The radiographers did perform additional ACL sequences in 63 patients (27%). Of these, 10 patients had a partial and 12 complete ACL tears. Only two patients (0.9%) were recalled for additional

    Full Text Available PURPOSE. To evaluate the role of single photon emission computed tomography (SPECT bone scan for the diagnosis of knee lesions in routine clinical practice. METHODS. 40 consecutive case records were examined in patients who underwent a SPECT scan prior to knee arthroscopy in routine clinical practice. The accuracy of clinical examination, SPECT scan results, and arthroscopic findings (as the gold standard in diagnosing knee lesions were compared. RESULTS. The sensitivity of SPECT scans in detecting medial meniscal, lateral meniscal, anterior cruciate ligament lesions, osteochondral defects, and chondromalacia patellae was 77%, 14%, 33%, 50%, and 74%, respectively. The specificities for the same structural lesions were high at 89%, 94%, 97%, 94%, and 69%, respectively. CONCLUSION. SPECT bone scan appears to be useful in the diagnosis of knee pathology in routine practice and in selecting patients for arthroscopy, especially most useful for the diagnosis of medial meniscal tears.

  17. Evaluation of anterior talofibular ligament injury with stress radiography, ultrasonography and MR imaging

    International Nuclear Information System (INIS)

    The purpose of this study was to clarify the efficacy of stress radiography (stress X-P), ultrasonography (US), and magnetic resonance (MR) imaging in the detection of the anterior talofibular ligament (ATFL) injury. Thirty-four patients with ankle sprain were involved. In all patients, Stress X-P, US, MR imaging, and arthroscopy were performed. The arthroscopic results were considered to be the gold standard. The imaging results were compared with the arthroscopic results, and the accuracy calculated. Arthroscopic findings showed ATFL injury in 30 out of 34 cases. The diagnosis of ATFL injury with stress X-P, US, MR imaging were made with an accuracy of 67, 91 and 97%. US and MR imaging demonstrated the same location of the injury as arthroscopy in 63 and 93%. We have clarified the diagnostic value of stress X-P, US, and MR imaging in diagnosis of ATFL injury. We obtained satisfactory results with US and MR imaging. (orig.)

    Femoroacetabular impingement (FAI is a condition characterized by the impingement of the femur and acetabulum. In Japan, this disorder has become recognized gradually. Here we report a rare case of surgically treated FAI, associated with an osseous protrusion on the acetabulum of a 30-year-old female. Plain computed tomography (CT and reconstructive 3D-CT images clearly demonstrated an anterolateral bony protrusion. Hip arthroscopy showed no degeneration of the cartilage on either the femoral or acetabular side, but degeneration at the edge of labrum was observed in the region of the bony protrusion. The complete removal of the bony protrusion under hip arthroscopy was thus considered impracticable, and a small skin incision was therefore made anteriorly to approach the acetabulum. The Short-Form 36-Item Health Survey (SF-36 revealed improvement in all scores.

  20. Meniscus tears of the knee: Postarthrogram high resolution CT

    International Nuclear Information System (INIS)

    Thirty-eight knees with clinically suspected meniscal tears were examined with high resolution computed tomography(HRCT) immediately following double contrast arthrography. All subsequently underwent arthroscopy. The findings of postarthrogram HRCT and arthroscopy were compared to evaluated the usefulness of postarthrogram HRCT in diagnosis of the meniscal tears. The sensitivity, specificity and accuracy of HRCT were 96.2%. 83.3% and 92.1% respectively. The anatomic details of the meniscal tears were clearly visible on the HRCT scans. Sagittal and coronal reformation views well visualized the horizontal tears and the relationship of torn meniscal fragments, and well differential the peripheral tears from the synovial recess. Our result indicate that postarthrogram HRCT not only is a sensitive and effective method for the detection and characterization of the meniscal tears, but also provides arthroscopists with the appropriate surgical plans

    We present a case of intraarticular myositis ossificans in the right knee of a child. Myositis ossificans (MO), though relatively rare in childhood and even more uncommon within a joint, should be included in the differential diagnosis of an intra-articular mass when indicated by the typical clinical, radiographic, and histologic findings. An 11-year-old male presented with a history of trauma to his right knee. Four weeks after the initial injury, an MRI demonstrated evidence of an ACL rupture with a ''cystic mass'' within the intercondylar notch along the anterior surface of the torn ligament. At subsequent arthroscopy, the mass noted on MRI was removed. The histology was consistent with MO. The authors believe this to be the first case of MO in the intercondylar notch detected by MRI, treated by arthroscopy, and confirmed by histology. (orig.)

  2. Shoulder imaging with MR, US, arthography, and arthoscopy

    International Nuclear Information System (INIS)

    To date, the true efficacies of shoulder imaging modalities remain uncertain, as no prospective study controlling for significant selection bias has been reported. A minimum of 25 double-blind examinations now have definitive confirmation, not selected by the imaging modalities. The images and interpretations were sealed in an envelope and blinded from the arthroscopist for initial arthroscopy, but second-look arthroscopy, and in some cases open surgery, was performed after unsealing the envelope. Therefore, negative and positive cases were equivalently tested. To date, MR imaging and US remain equally sensitive (85%) for detection of rotator cuff tears, but the combination is more sensitive (90%), and both are more sensitive than arthrography. Arthrography increased specificity when MR imaging and US in combination appear useful for diagnosis of biceps tendinitis

    2001-05-01

    Objective: To evaluate the efficacy of direct MR arthrography for diagnosing plica synovialis mediopatellaris (PSM). Material and Methods: Twenty-two knees of 19 patients were examined by direct MR arthrography. In 19 of those knees, field-echo T2*-weighted transaxial images were obtained with intra-articular administration of 40 ml of saline (direct MR arthrography). In the other 3 knees, T1-weighted transaxial images were obtained with intra-articular administration of 40 ml of gadopentetate dimeglumine. Conventional MR images were evaluated prior to direct MR arthrography in 12 of the 22 knees. The results of direct MR arthrography and conventional MR imaging were compared with the arthroscopic findings. Results: Direct MR arthrography demonstrated 17 of 19 PSMs proved on arthroscopy. The features of 16 PSMs on direct MR arthrography corresponded accurately with the arthroscopic classification. Conventional MR demonstrated only 3 plicae. Conclusion: Direct MR arthrography enabled accurate diagnosis of PSMs and could replace diagnostic arthroscopy.

  4. Arthroscopic anatomy of the subdeltoid space

    2013-09-01

    Full Text Available From the first shoulder arthroscopy performed on a cadaver in 1931, shoulder arthroscopy has grown tremendously in its ability to diagnose and treat pathologic conditions about the shoulder. Despite improvements in arthroscopic techniques and instrumentation, it is only recently that arthroscopists have begun to explore precise anatomical structures within the subdeltoid space. By way of a thorough bursectomy of the subdeltoid region, meticulous hemostasis, and the reciprocal use of posterior and lateral viewing portals, one can identify a myriad of pertinent ligamentous, musculotendinous, osseous, and neurovascular structures. For the purposes of this review, the subdeltoid space has been compartmentalized into lateral, medial, anterior, and posterior regions. Being able to identify pertinent structures in the subdeltoid space will provide shoulder arthroscopists with the requisite foundation in core anatomy that will be required for challenging procedures such as arthroscopic subscapularis mobilization and repair, biceps tenodesis, subcoracoid decompression, suprascapular nerve decompression, quadrangular space decompression and repair of massive rotator cuff tears.

  5. Anterior approach for knee arthrography

    International Nuclear Information System (INIS)

    Objective. To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for knee arthroscopy.Design. An anterior approach to the knee joint was devised mimicking anterior portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidance a needle was advanced from a position adjacent to the patellar tendon into the knee joint. After confirmation of the needle tip location, a dilute gadolinium solution was injected.Results and conclusion. All the arthrograms were technically successful. The anterior approach to knee MRA has greater technical ease than the traditional approach with little patient discomfort. (orig.)

    The purpose of this study was to clarify the efficacy of stress radiography (stress X-P), ultrasonography (US), and magnetic resonance (MR) imaging in the detection of the anterior talofibular ligament (ATFL) injury. Thirty-four patients with ankle sprain were involved. In all patients, Stress X-P, US, MR imaging, and arthroscopy were performed. The arthroscopic results were considered to be the gold standard. The imaging results were compared with the arthroscopic results, and the accuracy calculated. Arthroscopic findings showed ATFL injury in 30 out of 34 cases. The diagnosis of ATFL injury with stress X-P, US, MR imaging were made with an accuracy of 67, 91 and 97%. US and MR imaging demonstrated the same location of the injury as arthroscopy in 63 and 93%. We have clarified the diagnostic value of stress X-P, US, and MR imaging in diagnosis of ATFL injury. We obtained satisfactory results with US and MR imaging. (orig.)

  11. The preliminary application of magnetic resonance arthrography in the diagnosis of acetabular labrale tears

    International Nuclear Information System (INIS)

    Objective: To investigate the application value of MR arthrography (MRA) in the diagnosis of acetabular lab ral tears. Methods: Fifteen patients with a high degree of suspected acetabular lab ral tears received fluoroscope-guided injection of the contrast media into the hip joint (hip arthrography) and fat-saturated spin-echo T1-weighted images were obtained in the coronal, sagittal, oblique-axial and radial planes. Hip arthroscopy was performed on 12 of them. Results: Lab ral tears which were diagnosed in 11 patients by hip MRA were confirmed at hip arthroscopy. One patient showed no MRA indication of lab ral tear, also showed normal on arthroscopy. Tear in the anterior-superior quadrant 10 cases of 12 joints (12/13), posterior-superior quadrant 1 case of a joint (1/13). In 11 patients who underwent arthroscopy, hip MRA diagnosed 3 (3/13) joints labrale tears in coronal planes, 10 (10/13) joints in sagittal planes and 13 (13/13) labrale tears in axial-oblique and radial planes. In 15 patients with 20 hip joints, 5 cases 6 joints (6/20) with normal acetabular sublabral sulcus were performed. Conclusions: MR arthrography of hip is a reliable method in the diagnosis of acetabular labrale tears. Scanning method should be included fat-saturated spin-echo T1-weighted images in sagittal and oblique-axial planes or sagittal plus radial planes. The diagnosis of torn posterior-inferior quadrant should pay attention to the existence of a normal variation. (authors)

  13. Standard sonography and arthrosonography in the study of rotator cuff tears

    International Nuclear Information System (INIS)

    Purpose. The aim of this study was to evaluate the sensitivity of ultrasonography, integrating standard ultrasound and arthrosonography after injecting a saline solution into the glenohumeral cavity in cases of suspected rotator cuff tears. Materials and methods. We respectively examinated 40 patients awaiting shoulder arthroscopy for suspected or diagnosed tears of the rotator cuff. A radiologist, unaware of the pre-operative diagnosis, performed an ultrasound scan on all the patients before and after the injection of saline solution into the glenohumeral cavity. The parameters considered were presence or absence of a rotator cuff injury; type of injury according to Snyder and its extent along the longitudinal and transverse planes; presence or absence of effusion into the articular cavity; subacromial/subdeltoid bursal distension. All the patients underwent arthroscopy either the same day of the day after the ultrasound examination. Results. Standard sonography showed 26 complete rotator cuff tears (type C according to Snyder), 2 partial tears (type B according to Snyder) and 12 intact rotator cuffs. Arthrosonography detected 31 complete rotator cuff tears (type C according to Snyder), 1 partial tear (type B according to Snyder) and 8 intact rotator cuffs. Arthroscopy identified 32 complete rotator cuff tears (type C according to Snyder), 1 partial tear (type B according to Snyder) and 8 intact rotator cuffs. Analysis of the results shows that, taking arthroscopy as the gold standard, the sensitivity of normal sonography is 81.2%, whereas that of arthosonography is 96.8% (p<0.05). Conclusions. On the basis of the data obtained in this study, standard sonography , integrated with the injection of a saline solution into the glenohumeral cavity, considerably increases the diagnostic sensitivity for rotator cuff tears. The authors suggest that arthrosonography can be used in the event of suspected rotator tears, when MRI is contraindicated

    2016-03-01

    Full Text Available OBJECTIVE The purpose of this study was to evaluate the reliability of clinical diagnosis compared to MRI findings in ligamentous and meniscal injuries with respect to arthroscopic confirmation as a gold standard. METHODS 485 patients with knee injuries were prospectively assessed by clinical evaluation and magnetic resonance imaging and correlated after therapeutic arthroscopy. The overall accuracy, clinically productive values of sensitivity and specificity was derived. The actual value of the test with respect to positive predictive and negative predictive value was also derived, taking arthroscopic findings as confirmatory. The overall partial and total agreement among the clinical, MRI and arthroscopy was documented. RESULTS The overall accuracy for clinical examination was 85, 92, 100 and 100 and accuracy for MRI was 90, 97, 97 and 97 for detecting medial meniscus, lateral meniscus, ACL and PCL tears respectively. Clinically lateral meniscus tears are difficult to diagnose clinically with negative predictive value (90 whereas ACL injuries do not need MRI for diagnosis as evident by a high negative predictive value (100 of clinical examination. Total agreement with the clinical findings confirmed by arthroscopy was 64.40% which was relatively high as compared to total agreement of MRI findings which was only 31.50%. We found similar total agreement versus total disagreement of both clinical and MRI to be only 2.74% indicating very high accuracy in clinical diagnosis of meniscal and ligamentous injuries combined. CONCLUSION The clinical evaluation alone is sufficient to diagnose meniscal and ACL/PCL pathologies and MRI should be considered only as a powerful negative diagnostic tool. The arthroscopy decision should not be heavily dependent on MRI for ligamentous injuries but reverse is true for meniscal lesions. MR evaluation functions as a powerful negative diagnostic tool to rule out doubtful and complex knee injuries.

    Fractures of distal radius account for up to 20% of all fractures treated in emergency department. Initial assessment includes a history of mechanism of injury, associated injury and appropriate radiological evaluation. Treatment options include conservative management, internal fixation with pins, bridging and non-bridging external fixation, dorsal or volar plating with/without arthroscopy assistance. However, many questions regarding these fractures remain unanswered and good prospective randomized trials are needed. PMID:25657938

    Labral tears are the most common pathology in patients undergoing hip arthroscopy and the most common cause of mechanical hip symptoms. Labral repair techniques have been described in the literature using suture anchors placed as close as possible to the acetabular rim without penetrating the articular surface. Optimal surgical technique for labral repair is very important, and an inappropriate entry point and guide angulation may lead to intra-articular penetration of the anchor, chondral da...

    Intraosseous ganglion cysts are rare causes of wrist pain. Surgical treatment of this pathologic condition yields good results and a low recurrence rate. The main complications are joint stiffness and vascular disturbances of the lunate bone. Wrist arthroscopy is a surgical technique that reduces the intra-articular operative area and therefore minimizes postoperative stiffness.

  5. Mucoid degeneration of the anterior cruciate ligament mistaken for ligamentous tears

    International Nuclear Information System (INIS)

    Objective. To describe the MR features of mucoid degeneration of the anterior cruciate ligament (ACL) in a series of patients with MRI findings that were mistaken for tears in the majority of cases but who were found to have an intact ligament at arthroscopy. We will suggest a pathologic entity corresponding to this finding and describe some characteristic features that can be used to identify this entity on MRI.Design. A retrospective analysis of 10 MRI examinations of the knee was performed after arthroscopic evaluation. Prearthroscopic MRI findings had been interpreted as a tear in six patients prospectively and in the remaining four the diagnosis of mucoid degeneration was suggested and ultimately proven. All patients had an intact ACL by preoperative clinical examination, examination under anesthesia, and at arthroscopy.Results. MRI examinations demonstrated an ill-defined ACL, greater in girth than the normal ligament and characterized by increased signal on all sequences. The high-signal ligament was oriented in the normal direction of the ACL. The overall appearance of the ligament was retrospectively described as like a celery stalk. Arthroscopy demonstrated mechanically intact ligaments with a normal to expanded external appearance. Probing of three of the ligaments caused a material to be expressed and pathologic evaluation resulted in the diagnosis of cystic, mucoid degeneration.Conclusion. Mucoid degeneration and an intact ACL can be suspected when an apparently thickened and ill-defined ligament with increased signal intensity on all sequences is identified in a patient with a clinically intact ligament.

  6. Sensitivity and specificity of vertically oriented lateral collateral ligament as an indirect sign of anterior cruciate ligament tear on magnetic resonance imaging

    International Nuclear Information System (INIS)

    To evaluate the correlation between anterior cruciate ligament (ACL) tear and straightened, vertically oriented lateral collateral ligament (LCL). This study included 556 patients who underwent MRI of the knee and were divided into three subsets based on ACL morphology. Subset 1 included patients with unequivocal normal ACL. Subset 2 included patients with unequivocal ACL tears. Subset 3 included patients with doubtful ACL who underwent arthroscopy. MR images were reviewed and sensitivity and specificity of vertically oriented LCL as an indirect sign of ACL tear were calculated. The MRI results were as follows: subset 1, out of 282 patients, 270 had oblique LCL and 12 demonstrated vertical LCL; subset 2, out of 212 patients, 189 demonstrated vertical LCL and 23 revealed oblique LCL; subset 3, out of 62 patients, 28 patients with vertical orientation of LCL had a possible ACL tear. Patients with oblique LCL orientation (34) were reported as probably having normal ACL. On comparison with arthroscopy, in 28 patients who we reported as having possible ACL tears, there were 17 patients with torn ACL. The rest of the 11 patients revealed no ACL tears. In the group of 34 patients in whom we reported possible normal, arthroscopy-confirmed tear in 5 patients. Sensitivity and specificity of vertical LCL as an indirect sign of ACL tear was found to be 88% and the specificity 92.85%. Vertically oriented LCL is a useful indirect MRI sign of ACL tear and aids in making a diagnosis, when ACL appearance is equivocal. (orig.)

  7. Three tesla magnetic resonance imaging of the anterior cruciate ligament of the knee: can we differentiate complete from partial tears?

    International Nuclear Information System (INIS)

    To determine the ability of 3.0T magnetic resonance (MR) imaging to identify partial tears of the anterior cruciate ligament (ACL) and to allow distinction of complete from partial ACL tears. One hundred seventy-two patients were prospectively studied by 3.0T MR imaging and arthroscopy in our institution. MR images were interpreted in consensus by two experienced reviewers, and the ACL was diagnosed as being normal, partially torn, or completely torn. Diagnostic accuracy of 3.0T MR for the detection of both complete and partial tears of the ACL was calculated using arthroscopy as the standard of reference. There were 132 patients with an intact ACL, 17 had a partial, and 23 had a complete tear of the ACL seen at arthroscopy. Sensitivity, specificity, and accuracy of 3.0T MR for complete ACL tears were 83, 99, and 97%, respectively, and, for partial ACL tears, 77, 97, and 95%, respectively. Five of 40 ACL lesions (13%) could not correctly be identified as complete or partial ACL tears. MR imaging at 3.0T represents a highly accurate method for identifying tears of the ACL. However, differentiation between complete and partial ACL tears and identification of partial tears of this ligament remains difficult, even at 3.0T. (orig.)

  8. The use of MRI in the diagnosis of anterior cruciate ligament tears

    International Nuclear Information System (INIS)

    The study was comprised of 143 patients (83 males and 60 females) undergoing arthroscopy for the anterior cruciate ligament (ACL), whose ages ranged from 10 to 82 years with a mean of 34.5. To determine the value of magnetic resonance imaging (MRI) in the diagnosis of ACL tears, the findings of MRI were correlated with arthroscopic findings. Using arthroscopy as the standard, the accuracy, sensitivity, and specificity of MRI were 97.9%, 98.1%, and 99.0%, respectively, for the diagnosis of ACL tears. MRI appearance of the ACL evaluated as normal on arthroscopy fell into three types: (A) hyperintense fibers before and after the hypointense band with clear margin, (B) hypointense band with unclear margin, and (C) slender hypointense band in front of the slightly hypointense thick fiber-like structure. MRI showed abnormal findings even for the ACL with favorable tension. MRI was of limited value in differentiating complete from partial tears and fresh from old tears, although it had the high ability to diagnose ACL tears. (N.K.)

    The scapholunate joint is one of the most involved in wrist injuries. Its stability depends on primary and secondary stabilisers forming together the scapholunate complex. This ligamentous complex is often evaluated by wrist arthroscopy. To avoid surgery as diagnostic procedure, optimization of MR imaging parameters as use of three-dimensional (3D) sequences with very thin slices and high spatial resolution, is needed to detect lesions of the intrinsic and extrinsic ligaments of the scapholunate complex. The paper reviews the literature on imaging of radial-sided carpal ligaments with advanced computed tomographic arthrography (CTA) and magnetic resonance arthrography (MRA) to evaluate the scapholunate complex. Anatomy and pathology of the ligamentous complex are described and illustrated with CTA, MRA and corresponding arthroscopy. Sprains, mid-substance tears, avulsions and fibrous infiltrations of carpal ligaments could be identified on CTA and MRA images using 3D fat-saturated PD and 3D DESS (dual echo with steady-state precession) sequences with 0.5-mm-thick slices. Imaging signs of scapholunate complex pathology include: discontinuity, nonvisualization, changes in signal intensity, contrast extravasation (MRA), contour irregularity and waviness and periligamentous infiltration by edema, granulation tissue or fibrosis. Based on this preliminary experience, we believe that 3 T MRA using 3D sequences with 0.5-mm-thick slices and multiplanar reconstructions is capable to evaluate the scapholunate complex and could help to reduce the number of diagnostic arthroscopies.

    To retrospectively determine characteristics of contrast-filled acetabular labral clefts in patients under the age of 17 years at MR arthrography (Mra) correlated with arthroscopy, which may impact the thinking regarding the existence of a sublabral sulcus. After IRB approval, 41 patients under the age of 17 who had MRa were identified. The following observations of contrast-filled clefts were assessed: (1) presence/absence, (2) location, (3) depth, (4) abnormal signal within the labrum and (5) shape (linear, gaping, complex). Fisher's exact and the Wilcoxon matched-pairs signed-rank test were performed. Interreader agreement was calculated with Cohen's k. Reader 1 found clefts in 41 %. Depth was less than half in 6 %, more than half in 65 % and full thickness in 29 %. Shape was linear in 53 %, gaping in 18 % and complex in 29 %. Signal changes occurred in 88 %. Reader 2 found clefts in 29 %. Depth was less than half in 17 %, more than half in 58 % and full thickness in 25 %. Shape was linear in 50 %, gaping in 42 % and complex in 17 %. Signal changes occurred in 50 %. None of the clefts fulfilled the criteria for a sublabral sulcus at MRa and arthroscopy. None of the clefts found in our subjects under the age of 17 years met the MRa and arthroscopy criteria for a sublabral sulcus, which supports the theory that such clefts represent labral tears.

  11. Chronic injuries of the cruciate ligaments

    International Nuclear Information System (INIS)

    The high incidence of cruciate ligament injuries as a result of acute knee trauma with hemartrosis and abuse of diagnostic arthroscopies call for a suitable radiological imaging of the central pivot. Computed Arthrotomography (CAT) was used to examine the knee joint in 20 cases of clinically suspected chronic cruciate ligament injury. The images were correlated with arthroscopic and/or arthrotomic findings. Thirteen lesions of the anterior cruciate ligament (ACL) (65%) were found, plus 1 lesion of the posterior cruciate ligament (PCL) (5%), 2 associated lesions of ACL + PCL (10%), and 4 normal cases. Confirmation of pathology was available in all cases but one by arthroscopy and/or surgery. The central pivot diseases were classified as follows: absence, detachement, partial or complete tear. CAT findings of cruciate ligament injuries are emphasized and the role of the technique as compared to arthroscopy is discussed. CAT is useful in 3-D evaluation of central pivot and detection of different cruciate ligament injuries, with high sensitivity-specifity for ACL and high specifity-moderate sensitivity for PCL. In the evaluation of the chronic unstable knee, CAT is highly accurate and gives the surgeon useful information towards the planning of therapeutic procedures. CAT is almost non-invasive, well tolerated and easy to perform in out-patients, which make it a first-choice procedure in the screening of chronic ligament injuries

  15. MR imaging evaluation of plica synoviallis mediopatellaris of the knee joint

    International Nuclear Information System (INIS)

    To evaluate the diagnostic ability of MR imaging for plica synoviallis mediopatellaris (PSM), we retrospectively reviewed the MR imaging findings of patellofemoral space in 20 knee joints of 11 patients. In all 20 knee joints, arthroscopy and MR imaging were available. MR imaging was performed with a 1.5 Tesla Magnetom (Siemens) using a round surface coil. Pulse sequences were SE (TR 600 ms/TE 26 ms), SE (TR 200 ms/TE 26,70 ms) and FLASH (TR 450 ms/TE 15 ms/FA 90deg). In six of the 20 knees with PSM proved by arthroscopy, a low intensity band was shown above the medial condyle of the femur on both T1- and T2-weighted MR images, and on FLASH images this band was shown as intermediate intensity. In the other 14 knees with no PSM observed by arthroscopy, the low intensity band was not shown on MR imaging. In all 20 knees, a similar low intensity band was shown about 1 cm cranial to the medial condyle of the femur. This should not be diagnosed as PSM. The low intensity band seen on T1- and T2-weighted MR images and its anatomical relation to the medial condyle are important in diagnosing PSM. (author)

    2012-10-01

    Full Text Available Abstract We report a thirteen-year-old tennis player with knee hemarthrosis caused by low factor XIII activity. She visited our hospital because of medial peripatellar pain for two years. Although there was no abnormal sign in X-ray or MRI, diagnostic arthroscopy was performed. It revealed some cartilage debris, medial plica and complete septum of suprapatellar plica. Removing the debris by washing out and resecting the medial plica, she could return to play tennis without perioperative symptom. Two months after the first operation, her knee got swelling without any apparent cause. Since 20 ml blood was aspirated twice and MRI revealed suprapatellar mass, we performed arthroscopy again. Suprapatellar mass was old blood clot covered with complete suprapatellar plica. Resection of suprapatellar plica and washing out blood clot were performed, and severe postoperative hemarthrosis was progressively occurred. As factor XIII level was 54% preoperatively, we diagnosed that this condition was caused by low activity level of the factor and administered factor XIII concentrates. The level got improved to 129% and then hemarthrosis gradually relieved. She had no signs of recurrence. We should keep in mind of low factor XIII activity case in case of unexplained postoperative hemarthrosis after arthroscopy because consumption of the factor might promote this condition.

  18. Magnetic resonance imaging findings in anterolateral impingement of the ankle

    International Nuclear Information System (INIS)

    Objective. To demonstrate the MR imaging findings of anterolateral impingement (ALI) of the ankle.Design and patients. Nine patients with a history of ankle inversion injury and chronic lateral ankle pain were imaged with MR imaging, and the findings correlated with the results of arthroscopy. Three additional patients with clinically suspected ALI of the ankle were also included. Ankle MR imaging studies from 20 control patients in whom ALI was not suspected clinically were examined for similar findings to the patient group.Results. MR imaging findings in the patients with ALI included a soft tissue signal mass in the anterolateral gutter of the ankle in 12 of 12 (100%) cases, corresponding to the synovial hypertrophy and soft tissue mass found at arthroscopy in the nine patients who underwent arthroscopy. Disruption, attenuation, or marked thickening of the anterior talofibular ligament was seen in all cases. Additional findings included signs of synovial hypertrophy elsewhere in the tibiotalar joint in seven of 12 patients (58%) and bony and cartilaginous injuries to the tibiotalar joint in five of 12 (42%). None of the control patients demonstrated MR imaging evidence of a soft tissue mass in the anterolateral gutter.Conclusions. ALI of the ankle is a common cause for chronic lateral ankle pain. It has been well described in the orthopedic literature but its imaging findings have not been clearly elucidated. The MR imaging findings, along with the appropriate clinical history, can be used to direct arthroscopic examination and subsequent debridement. (orig.)

  19. Osteochondritis (osteochondrosis) dissecans: A review and new MRI classification

    1998-02-01

    Osteochondritis (osteochondrosis) dissecans (OCD) is a common condition in children, adolescents, and young adults. Describing OCD together with osteochondral fractures and epiphyseal ossification disturbances and considering these three conditions as one entity has caused much confusion. Age distribution and localization combined with the radiologic and surgical presentation distinguishes these conditions. Osteochondritis dissecans represents an osseous lesion with secondary involvement of the overlying cartilage. Beginning as avascular osteonecrosis, OCD forms a transitional zone that harbors the potential of restoration with complete healing or progression to an osseous defect. Mechanical and traumatic factors are etiologically dominant in OCD, but a predisposition seems to be a contributing factor in some patients. Osteochondritis dissecans is generally diagnosed by conventional radiology. Its therapy is determined by the stage of the lesion and MRI will become the method of choice for staging. Intact cartilage, contrast enhancement of the lesion, and absent ``cystic`` defects are findings of MRI stage I and justify conservative therapy, obviating arthroscopy. Cartilage defect with or without incomplete separation of the fragment, fluid around an undetached fragment, and a dislodged fragment are MRI findings observed in stage II and require arthroscopy with possible intervention. Thus, MRI can noninvasively separate non-surgical from possibly surgical lesions and should replace diagnostic arthroscopy. (orig.) With 13 figs., 4 tabs., 49 refs.

    Arthroscopy has become indispensable for performing tibiotalar and subtalar arthrodesis. Now in 2015, it is the gold-standard surgical technique, and open surgery is reserved only for cases in which arthroscopy is contraindicated: material ablation after consolidation failure, osteophytes precluding a work chamber, excentric talus, severe malunion, bone defect requiring grafting, associated midfoot deformity, etc. The first reports of arthroscopic tibiotalar and subtalar arthrodesis date from the early 1990s. Consolidation rates were comparable to open surgery, but with significantly fewer postoperative complications: infection, skin necrosis, etc. Arthroscopy was for many years reserved to moderate deformity, with frontal or sagittal deviation less than 10°. The recent literature, however, seems to extend indications, the only restriction being the surgeon's experience. Tibiotalar arthrodesis on a posterior arthroscopic approach remains little used. And yet the posterior work chamber is much larger, and initial series showed consolidation rates similar to those of an anterior approach. The surgical technique for posterior tibiotalar arthrodesis was described by Van Dijk et al., initially using a posterior para-Achilles approach. This may be hampered by posterior osteophytes or ankylosis of the subtalar joint line (revision of non-consolidated arthrodesis, sequelae of calcaneal thalamus fracture) and is now used only by foot and ankle specialists. Posterior double tibiotalar-subtalar arthrodesis, described by Devos Bevernage et al., is facilitated by transplantar calcaneo-talo-tibial intramedullary nailing. PMID:26797006

    To evaluate the feasibility of cine MRI for the detection of scapholunate dissociation (SLD) and to compare the sensitivity and specificity of cine MRI with those of cineradiography and arthroscopy. To evaluate feasibility, healthy subjects underwent cine MRI of the wrist. To evaluate sensitivity and specificity, patients with clinically suspected scapholunate ligament (SLL) injury after trauma to the wrist were prospectively included and underwent radiographic examination, cineradiography, and cine MRI. In 25 out of 38 patients, subsequent arthroscopy was performed. Results of cineradiography and cine MRI correlated with those of arthroscopy. Cine MRI was of diagnostic quality in all healthy subjects and patients with good interrater agreement. There was excellent correlation between cineradiography and cine MRI. Scapholunate distance differed significantly between healthy subjects and patients with scapholunate dissociation (p < 0.001), but not between imaging modalities in the patient group. Cine MRI had 85 % sensitivity and 90 % specificity for the detection of SLD. Cine MRI of the wrist is a fast and reliable technique for the detection of SLD with diagnostic accuracy comparable to cineradiography. It can be easily implemented as a routine clinical MRI examination, facilitating diagnostic workup of patients with suspected SLD while avoiding radiation exposure. (orig.)

  2. Rotator cuff injury: fat suppression MR image

    International Nuclear Information System (INIS)

    We performed the study prospectively to evaluate the advantage of fat suppression MR in the diagnosis of rotator cuff injury. Ten symptomatic patients were studied with both conventional T2WI and FST2WI using chemical shift technique. Each image was analyzed for the assessment of injuries, conspicuity of the lesion, the presence of effusion in subacromical bursae and joint space, and presence of humeral head injury. Arthroscopy was done in 4 patients following MRI. We could made presumptive diagnoses on FSMR as identical as on conventional MR in six cases(1 normal, 2 tendinitis, 2 partial thickness tear, 1 full thickness tear), two of them were confirmed by arthroscopic procedures. Two cases of partial thickness tear proved by arthroscopy were detected on FST2WI, whereas they were considered tendinitis on conventional T2WI. There were another 2 cases who showed tendinitis on FSMR, but normal on conventional T2WI. They, however, were not confirmed by either arthroscopy or surgical procedure. We found the FSMR were superior to conventional T2WI in the conspicuity of lesions and detection of joint effusion and abnormalities on the humeral head. We think FSMR of the shoulder could have significant diagnostic advantages over the conventional spin-echo MR imaging

    The orthopaedic surgeons cannot predict the functional results after a distal intra articular radius fracture. The intra-articular incongruity of more than 1 mm is associated with the development of secondary osteoarthrosis. The wrist arthroscopy became an essential help for the reduction of these fractures. The hand is normally in an upright position with a traction of approximately 4-5 kg which facilitates the reduction of the extra-articular fracture component. It is possible to use a technique of horizontal traction. The arthroscopy allows the reduction and control of the fixing of the various fragments, but also the treatment associated lesions associated. One randomized study, which compared 34 arthroscopically treated fractures with 48 openly treated, concluded that the arthroscopy-treated group had better outcome, better reduction, better grip strength and better range of motion than the openly treated group. The treatment of intra articular distal radius fractures with arthroscopic assistance is thus the guaranteeing of the most anatomical reduction of articular surface. It allows the diagnosis and the treatment of the associated lesions, decreases the peripheral fibrous scars of soft tissues by avoiding initially extensive approaches and finally gives better functional results.

    The clinical outcome of an intraarticular distal radius fracture is generally thought to be associated with the following factors: amount of radial deformity, joint congruity, and associated soft-tissue injuries. The proposed technique to manage this fracture pattern that involves a displaced volar lunate facet fragment uses wrist arthroscopy and pinning. Distraction of the fracture before arthroscopy is accomplished either by external fixation or by the arthroscopy tower. A freer elevator is introduced dorsally to disimpact the fragments, and next, a nerve hook is used to reduce the volar lunate facet, which is subsequently pinned to the radial styloid. The remaining fragments are reduced with interfragmentary pin fixation, and this anatomical articular construct is fixed to the radial metaphysis. The advantages of this technique are: (a) accurate assessment of articular congruency by direct visualization, (b) identification and repair of associated lesions, and (c) minimal soft tissue disruption. Potential disadvantages of external fixation supplemented by interfragmentary pins may be that it does not provide for rigid stable fixation, and therefore, does not allow for early motion compared to open reduction and internal fixation. Furthermore, it is technically challenging, and is therefore suggested as an alternative for the aforementioned fracture pattern. PMID:16974217

    The optimal forearm boom should facilitate dynamic investigation of the wrist and approaches for wrist arthroscopy. It should be safely fixed at the operating table without any contact with the patient. It must be compatible with the arm of any patient and should be sterilisable. Repositioning of distal radius fractures, fluoroscopy and insertion of Kirschner-wires should not be restricted. According to these criteria the current investigators designed a new forearm boom which was subsequently used in 19 wrist arthroscopies and 9 distal radius fracture fixations. Twenty-eight patients with heights between 150 and 205 cm and forearm lengths between 17.5 to 37 cm were treated. Preoperatively, wrist motion was tested in those 19 wrists, that underwent wrist arthroscopy, before and after fixation by the forearm boom and any restriction due to usage of the novel device was found. The new forearm boom satisfied all of the criteria cited above. Therefore the current authors believe the new forearm boom may be valuable for the indications mentioned. PMID:21209480

    Wrist arthroscopy for the distal radius fractures is an effective adjunct to evaluate the reduction of intraarticular fragments and soft tissue injuries. In recent years, volar locking plate fixation has become popular, and arthroscopic procedures for distal radius fracture reduction have become problematic because vertical traction has to be both on and off during surgery. We developed a plate presetting arthroscopic reduction technique to simplify the combination of plating and arthroscopy. The fracture was reduced, and anatomic alignment was regained under an image intensifier, and then the volar locking plate was preset. Wrist arthroscopy was introduced under vertical traction, and the intraarticular condition was assessed. If dislocations of the intraarticular fragments were residual, they were reduced arthroscopically, and soft tissue injuries were treated subsequently. Finally, the traction was removed, and the plate was securely fixed. Since May 2005, the authors have used this technique in more than 50 patients. This article will review the history, indications, contraindications, technique, rehabilitation, and complications for the plate presetting arthroscopic reduction technique for distal radius fractures.

    Full Text Available Clinical, arthrographic, and arthroscopic findings in 53 patients with acutely torn anterior cruciate ligaments (ACLs were documented. Arthroscopy and instability tests under anesthesia were performed on all patients within 2 weeks after the initial injury. Twenty-three patients complained of extension blocks, and localized tenderness on the medial side was revealed in 26 patients at the initial examination. Aspiration from joints exhibited hemarthrosis in 52 patients. Arthroscopy revealed ACL ruptures in all patients. Four Segond's fractures, 26 meniscus tears (8 medial and 18 lateral, 1 osteochondral fracture, and 19 medial collateral ligament ruptures were revealed. Arthroscopy detected only 1 of the 5 ruptures of the posteromedial corner of the medial meniscus, which were noted on arthrography. Three ACL stumps were protruding among the femorotibial joint, which seemed to be restricting full extension. Statistical analysis showed that tenderness on the medial side was not revealed more frequently in knees with medial collateral ligament injuries than in the others. The volume of aspirated fluids in knees with no leakage in arthrography significantly increased over those with leakages (p < 0.05. Diagnosis of ACL injuries should be completed by clinical, arthrographic, and arthroscopic examinations.

  9. Juvenile osteochondritis dissecans: a 5-year review of the natural history using clinical and MRI evaluation

    International Nuclear Information System (INIS)

    Although MRI prognostic features for juvenile osteochondritis dissecans (JOCD) have been determined, the natural history of JOCD on serial MRI has not been fully documented. To document the natural history of JOCD on serial MRI and to correlate this with arthroscopy and clinical outcome over a 5-year follow-up. Twenty-one knees in 19 patients (15 boys, 4 girls; age range 5-15 years) with JOCD underwent MRI and clinical follow-up over 5 years. Lesions were classified as stable or unstable on MRI and compared with clinical and arthroscopic data. On 5-year follow-up, 17 of 19 patients were asymptomatic and 2 of 19 had minimal pain. Fourteen arthroscopies were performed on 11/21 knees. One of twenty-one had fragment fixation. On initial MRI, eight knees had marked fragmentation, high signal at the fragment/bone interface and incomplete defects in the hyaline cartilage (MRI stage III-stable), but no tear. Of these, five had arthroscopy, all confirming intact cartilage. One of twenty-one knees was unstable (MRI stage IVb) with a detached osteochondral fragment, requiring surgery. Despite extensive subchondral bone changes on MRI, all cases with intact cartilage (95%) improved with conservative treatment. Early MRI allows prompt diagnosis and institution of conservative treatment. This results in healing and avoidance of surgery in most patients. (orig.)

    Objective. To demonstrate the MR imaging findings of anterolateral impingement (ALI) of the ankle.Design and patients. Nine patients with a history of ankle inversion injury and chronic lateral ankle pain were imaged with MR imaging, and the findings correlated with the results of arthroscopy. Three additional patients with clinically suspected ALI of the ankle were also included. Ankle MR imaging studies from 20 control patients in whom ALI was not suspected clinically were examined for similar findings to the patient group.Results. MR imaging findings in the patients with ALI included a soft tissue signal mass in the anterolateral gutter of the ankle in 12 of 12 (100%) cases, corresponding to the synovial hypertrophy and soft tissue mass found at arthroscopy in the nine patients who underwent arthroscopy. Disruption, attenuation, or marked thickening of the anterior talofibular ligament was seen in all cases. Additional findings included signs of synovial hypertrophy elsewhere in the tibiotalar joint in seven of 12 patients (58%) and bony and cartilaginous injuries to the tibiotalar joint in five of 12 (42%). None of the control patients demonstrated MR imaging evidence of a soft tissue mass in the anterolateral gutter.Conclusions. ALI of the ankle is a common cause for chronic lateral ankle pain. It has been well described in the orthopedic literature but its imaging findings have not been clearly elucidated. The MR imaging findings, along with the appropriate clinical history, can be used to direct arthroscopic examination and subsequent debridement. (orig.)

    Although in widespread clinical use, evidence of the diagnostic accuracy of radiographic parameters for the diagnosis of scapholunate ligament injuries is scarce. The objective of this study was to evaluate the scapholunate (SL) angle, radiolunate (RL) angle and SL gap as diagnostic parameters for these lesions. Eight hundred forty nine patients, who underwent wrist arthroscopy at our institution because of wrist pain were included in a retrospective analysis. In all patients the SL angle, RL angle and SL gap were measured on preoperative radiographs. These parameters were correlated with the actual finding of the SL ligament during arthroscopy. Optimal test thresholds were calculated as well as sensitivity, specificity and the likelihood ratios of each parameter. All three parameters proved useful in statistical analysis. The optimal cut-off points for diagnosing lesions of the SL ligament were calculated as 62.5 for the SL angle, 12.5 for the RL angle and 2.5 mm for the SL gap. SL angles had the greatest specificity (0.93). We were able to validate plain radiographs as a reliable tool in the work-up of patients with suspected SL ligament injuries. However, wrist arthroscopy remains the gold standard in diagnosing and treating these lesions. (orig.)

    Magnetic Resonance Imaging (MRI) shows, in the post-traumatic knee, a fairly high number of bone and cartilage injuries missed by conventional radiography and therefore called occult. Our aim is to classify these injuries, to correlate their site and distribution with associated menisco-ligamentous injuries and with trauma mechanisms. Thirty-eight patients with a history of acute knee trauma and negative X-ray findings were examined with MRI within 15 days of trauma. 1.5- and 0.5-T units and SE T1-weighted GE T2*-weighted and SE T2-weighted sequences were used. The injuries were classified as intraosseous and osteochondral bruises or fractures. Twenty-three patients with menisco-ligamentous injuries were submitted to therapeutic arthroscopy; the sites of bone and cartilage injuries depicted with MRI were studied with arthroscopy. Seven patients were followed-up with MRI at 6-12 months to investigate subchondral injury evolution: 5 of 7 patients were also submitted to arthroscopy. MRI showed a statistically significant correlation between site and distribution of bone and cartilage injuries and between internal derangement and trauma mechanisms, i.e., contusion, distortion, stress. In our experience, MRI could identify and characterize occult subchondral injuries, thus allowing appropriate treatment. PMID:8685452

    Full Text Available ABSTRACT : BACKGROUND & OBJECTIVE : Trauma to knee joint is a significant cause of morbidity in the young, active individuals and athletes. An accurate diagnosis regarding the type and extent of injuries is essential for early operative as well as non - o perative treatment. The most widely u sed diagnostic modalities to assess the joint in jury are arthroscopy and MRI. Arthroscopy, though accurate, is invasive and can cause complications. Magnetic resonance imaging (MRI has now been accepted as the best imaging modality for non - invasive evalu ation of knee injuries. This study was undertaken to study the types and incidence of injuries in traumatic knee joint by MR imaging and to compare with arthroscopy findings in selected cases. METHODS: DESIGN : Prospective study Setting: In a tertiary care hospital, symptomatic patients who were referred from various service referral hospitals and units with history of trauma and clinical suspicion of IDK were referred to department of O rthopedics , Navodaya Medical College, Raichur. Patients: 50 consecutive pa tients with suspicion of IDK following knee trauma were selected for the study from 2011 to 2013. INVESTIGATIONS: Clinical examinations, MRI knee (within 4 days of referral & in selected cases arthroscopy were performed and the findings were compared. Mai n Outcome Measures: Study of spectrum of MRI findings in traumatic knee and correlation of MRI findings with arthroscopy/surgical findings in selected cases. RESULTS : Of the total 50 patients evaluated, most common injury was ACL tear of which complete te ars were more common. PCL tears were less common. Among the Meniscal injuries, MM tears are more common than LM and grade 2 tears are more common in both. MCL tears outnumbered LCL tears and grade 1 and 2 tears are more common in MCL. Osseous/Osteochondra l lesions were seen in 17 patients (34%. Most of these were bony contusions involving the femoral and tibial condyles. INTERPRETATION AND

  15. Direct MR arthrography in the diagnosis of injury of the triangular fibrocartilage complex in the wrist

    International Nuclear Information System (INIS)

    Objective: To compare direct magnetic resonance (MR) arthrography with arthroscopy of the wrist for evaluation of injury in the triangular fibrocartilage complex (TFCC). Methods: Fourteen cases with suspicion of injury of triangular fibrocartilage complex were performed with conventional MR and direct MR arthrography, 10 cases were done by arthroscopy. In the direct MR arthrography, needle placement was obtained using clinical landmark under sterile technique and fluoroscopy, intra-articular injection was performed at the radius-scaphoid space with 5-7 ml 0.3% mixture of Gadolinium (0.1 mmol/ L) and saline(0.3 ml Gd-DTPA + 100 ml saline). The findings of MRI and MR arthrography were analyzed with results of arthroscopy. Results: (1) Among 14 cases with injury of TFCC, there were ulnar tear in 5 cases, radius tear in 4 cases, complete tear in 5 cases (included 2 cases with long term rheumatoid). (2) High signal intensity and isointensity signal of injury of TFCC were revealed on STIR or T2WI and T1WI respectively, normal hypointensity signal of the TFCC was partially or completely absent. Contrast media at the ulnar insertion (5 cases with ulnar tear) or radius attachment of the TFCC (4 cases with radius tear) were seen in the MR arthrography with different extent, 5 cases with complete tear showed contrast media at the both ulnar insertion and radius attachment of the TFCC. The findings of MR arthrography were well corresponded with results of arthroscopy on the lesion site, including ulnar tear in 3 cases, radius tear in 4 cases and complete tear in 3 cases. (3) Among 14 cases with TFCC, 8 cases had dislocation of radius-ulnar joint, 6 cases had bone contusion of radius or ulnar, synovial reaction was also clearly depicted on conventional MRI and direct MR arthrography in all cases. Conclusion: Compared with results of arthroscopy, direct MR arthrography can adequately reveal the injury of the triangular fibrocartilage complex, synoviat reaction and edema changes

The agent was noted to have a positive effect at the stage of hyperhydration and dechondral changes and in grade I–II intrachondral changes and to be able to prevent or stop the progression of OA in later (II–III X-ray stages. The effect of synvisc did not depend on disease duration and patient age, but it decreased in the presence of marked articular anatomic and morphological changes. The administration of the agent could reduce or preclude the use of nonsteroidal anti-inflammatory drugs or intraarticular glucocorticoids n 96% of cases.Conclusion. Arthroscopy and MRI make possible to recognize arthrosis in its earliest stage and to monitor the effect of drugs on the cartilage. The use of synvisc in early-stage gonarthrosis allows a long-term symptomatic effect and some structure-modifying activity.

    To evaluate the diagnostic value of MRI of the shoulder. Between January and June 1997, shoulder MRI and arthroscopy were performed in a total of 48 patients with shoulder pain (n=3D30) or shoulder instability (n=3D18). Forty-five were males and three were females; their ages ranged from 16 to 67 (mean 32.5) years. The period between shoulder MRI and arthroscopy was between one and 390 (mean, 42.2) days. Twenty-six patents underwent MR arthrography (AMR), and 22 conventional MRI(CMR). Each image was analyzed for rotator cuff injury, glenoid labral injury, SLAP lesion, and biceps tendon injury. On arthroscopy, one disease was found in 34 patients, two were found in six, three diseases were found in seven, and one patient had four diseases. Arthroscopic diagnosis was as follows:rotator cuff injury, 29;SLAP lesion, 12;glenoid labral injury, 10;biceps tendon injury, 4;subacromial bursitis, 2;chronic synovitis, 1;adhesive capsulitis, 1;superior glenohumeral ligament injury, 1;normal, 1. For rotator cuff injury, the sensitivity of MRI was 65.5% and specificity was 93.0% (AMR:66.7%, 95.8%, CMR:65.2%, 86.4%). For SLAP lesion, sensitivity was 58.3% and specificity was 97.2% (AMR:66.7%, 100%, CMR:50%, 93.8%);for glenoid labral injury, sensitivity was 80.0% and specificity was 89.5% (AMR:85.7%, 84.2%, CMR:66.7%, 94.7%), and for biceps tendon injury, the false negative rate was 100%. In cases involving glenoid labral injury, the diagnostic accuracy of shoulder MRI was relatively high;in rotator cuff injury and SLAP lesion, however, diagnosis was limited, and in biceps tendon injury was difficult. We suggest, however, that MR arthrography has certain diagnostic advantages over conventional MRI.=20.

  19. Evaluation of anterior cruciate ligament ruptures by three dimension MR imaging

    International Nuclear Information System (INIS)

    Objective: To compare the diagnostic performance of conventional 2D and 3D Cube MR imaging to identify complete and partial tears of anterior cruciate ligament (ACL). Methods: Forty patients suspected of having tears of anterior cruciate ligament were prospectively studied by 3.0 T conventional 2D and 3D Cube MR imaging and arthroscopy. MR images were interpreted in consensus by two experienced radiologists, and the ACL was diagnosed as being normal, partially torn, or completely torn. Diagnostic accuracy of 2D and 3D Cube MR for the detection of both complete and partial tears of ACL was calculated using arthroscopy as the standard of reference. Area under curve (AUC) of both methods were calculated using ROC curves and were compared using Hanley and McNeil curve comparison. Results: Sixteen patients had intact ACL, 12 had complete tear, and 12 had partial tear of the ACL at arthroscopy. For complete ACL tear, AUC of 2D MR and 3D Cube was 0.839 and 0.923 respectively, and there was no significant difference on ROC curves (Z=1.245, P=0.213). For partial ACL tears, AUC of 2D and 3D Cube MR were 0.643 and 0.881 respectively, and there was significant difference on ROC curves (Z=2.384, P=0.017). Conclusions: Both 2D MR and 3D Cube MR have high sensitivity and specificity for identifying the complete ruptures of ACL. 3D Cube MRI appears to be superior identifying partial rupture of ACL.

    Background The patellofemoral joint is perhaps the most commonly involved compartment in knee osteoarthritis (OA). Radiographic studies are routinely ordered and are seen as the first-line investigations for patellofemoral osteoarthritis (PFOA). The Kellgren-Lawrence (K&L) grading scale is often used to quantify the severity of radiographic OA. In this study, we aim to determine the correlation of the K&L grading scale on both the skyline and lateral views with arthroscopic visualization of articular cartilage damage. Methods All patients with clinical and radiographic features of PFOA who underwent knee arthroscopy by a single surgeon from 2006 to 2010 in our institution were reviewed. The study group consisted of 66 patients with PFOA. All patients had skyline and lateral radiographs of the knee taken before surgery. All patients had arthroscopic evidence of PFOA. Blinded investigators graded the radiographs according to the K&L grading scale. At arthroscopy, the patellofemoral joint was graded according to the Outerbridge classification. Correlation and statistical analysis of the radiographic and arthroscopic grade was carried out. Results The general trend shows that the higher the radiographic K&L grading, the greater the severity of articular cartilage degeneration on arthroscopy. However, an increasing K&L grade accounts for only 39.7% and 28.4% of the variation of severity of arthroscopically-determined articular cartilage degeneration on skyline and lateral views respectively. Interestingly, on both views, better correlation with arthroscopic findings was seen in early (K&L grades 1 and 2) PFOA. Skyline views were superior to lateral views in terms of specificity, PPV, NPV and accuracy in predicting early OA. Conclusions Skyline radiographs are more accurate than lateral radiographs in prediction of severity of PFOA. PMID:26605309

    Background. In magnetic resonance imaging (MRI) with 3D-double-echo steady-state (3D-DESS) sequences, the cartilage-synovial fluid contrast is reported to be better with a flip angle of 90 deg than with the conventional flip angle of 40 deg, and the detection rate of knee cartilage injury may be improved. Purpose. To compare the diagnostic performance and certainty of diagnosis with 3D-DESS images made using two flip angle settings, 40 deg and 90 deg, for knee cartilage surface lesions of Grade 2 or above confirmed by arthroscopy. Material and Methods. Images were obtained with 3D-DESS flip angles of 40 deg and 90 deg at 1.0T in 13 consecutive patients (2 men, 11 women, age range 18-68 years) evaluated for superficial cartilage injury by arthroscopy. Two radiologists classified the presence or absence of cartilage damage of >=Grade 2 as 'positive (p)' or 'negative (n)', respectively. The rate of agreement with arthroscopic diagnosis was then examined, and the diagnostic performance compared. Diagnostic confidence was assessed scoring the presence or absence of cartilage damage into three categories: 3 = can diagnose with absolute confidence; 2 = can diagnose with a level of certainty as probably present or probably absent; and 1 = cannot make a diagnosis. Results. In a comparison of the rate of agreement between diagnosis by 3D-DESS images and arthroscopy, the rate of agreement was significantly higher and diagnostic performance was better in 90 deg images for the medial femoral condyle only. Diagnostic confidence was significantly better with 90 deg flip angle images than with 40 deg flip angle images for all six cartilage surfaces. Conclusion. In evaluating knee cartilage surface lesions with 3D-DESS sequences, a flip angle setting of 90 deg is more effective than the conventional setting of 40 deg

    Background As the triangular fibrocartilage complex (TFCC) anchors the distal radius to the ulna via the radioulnar ligament (RUL), a severely displaced distal fragment of the radius may be associated with a foveal avulsion of the TFCC. The purpose of this retrospective study was to assess, radiographically and arthroscopically, the relationship between displacement of the radius, the ulnar styloid, and avulsion of the RUL resulting in distal radioulnar joint (DRUJ) instability. Materials and Methods Twenty-nine wrists of 29 patients with intra- and extra-articular distal radius fractures/malunion who underwent reduction or a corrective osteotomy of the displaced/malunited fracture, and/or wrist arthroscopy, were assessed radiographically and arthroscopically. Radial translation, radial inclination, radial shortening, volar or dorsal tilt, and the presence of an ulnar styloid fracture with more than 4 mm of displacement were measured from the initial films. Radiocarpal arthroscopy was used to assess peripheral lesions of the TFCC, while DRUJ arthroscopy was used to assess the foveal attachment. The relationship between displacement of the distal radius or the ulnar styloid fracture and the TFCC injury, including avulsion of the RUL, was recorded. Results Univariate analysis revealed that increased radial translation, decreased radial inclination, increased radial shortening, and an ulnar styloid fragment radially displaced by more than 4 mm were significant predictors of RUL avulsion at the fovea. Volar or dorsal tilt of the radius and ulnar variance did not correlate with RUL avulsion or TFCC injuries. Multiple logistic regression analysis revealed that radial translation was an independent risk factor of foveal avulsion of the RUL. Conclusions Increased radial translation and radial shortening and decreased radial inclination of the distal fragment can be associated with a foveal avulsion of the RUL. Radial translation can be an independent risk

    Background Soft tissue injuries associated with distal radius fractures have been reported by some authors. Arthroscopy can be used to evaluate the condition of the articular surface and intracarpal soft tissues and as an aid to treatment. There are three intracarpal soft tissues of particular importance: the triangular fibrocartilage complex (TFCC), the scapholunate interosseous ligament (SLIL), and the lunotriquetral interosseous ligament (LTIL). The purpose of this study was to evaluate intracarpal soft tissue injuries and their relationships with fracture types during arthroscopic surgical treatment of distal radius fractures. Methods Eighty-nine patients in our hospital underwent surgical treatment by arthroscopy for a fracture of the distal end of the radius. They ranged in age from 17 to 92 years (mean, 62.2 years), and comprised 20 men (mean age, 45.6 years) and 69 women (mean age, 66.5 years). The AO classification data on plain radiographs indicated A2 fracture in four patients, A3 fracture in 10 patients, C1 fracture in two patients, C2 fracture in 24 patients, and C3 fracture in 49 patients. Wrist arthroscopy was performed with vertical traction, and intracarpal soft tissues were examined. For assessment of the TFCC in the radiocarpal space, the Palmar classification was used. For assessment of the SLIL and LTIL in the midcarpal space, the Geissler classification was used. Results TFCC injury was present in 59% of cases, SLIL injury in 54.5% of cases, and LTIL injury in 34.5% of cases. Only 17.1% of patients (14/82 patients) were negative for all three types of injury. In 81% of cases (72/89 patients), some intracarpal soft tissue injury was present in association with the fracture. Conclusions The fracture was complicated by TFCC injury in 59% of patients, SLIL injury in 54.5% of patients, and LTIL injury in 34.5% of patients, irrespective of the fracture type. PMID:24004506

    2006-11-01

    Ulno carpal abutments secondary to the sequels of a fracture of the radius are often due to the inversion of the distal radio ulnar index by shortening relative to the radius. This positive ulnar variance eventually leads to an abutment between the head of the ulnar and the proximal articular face of the lunate with alteration of the cartilaginous carpal surfaces. The wrist arthroscopy makes diagnosis and treatment possible in a less invasive way. The patients are operated on as outpatients under local regional anaesthetic using a pneumatic tourniquet. The arthroscope is positioned using the 3-4 radio carpal opening permitting exploration of the joint. The surgical treatment is performed by arthroscopy using a burr and going in through the 6R radio carpal opening. In this way we use the technique of partial resection of the distal ulna. We have a series of 62 patients who have benefited from the technique of partial resection of the ulnar head by arthroscopy. There were 30 men and 32 women. The average age was 66 years old (between 45 and 82). Our average follow-up is 32 months (between 12 and 60 months). Recovery of mobility was immediate in all cases with persistent pain in the radio ulnar joint in 8 cases. Arthroscopic treatment of ulno carpal abutment has proved itself effective and innocuous. It should nevertheless be reserved for operations on small sized inversions of the distal radio ulnar index (less than 5 mm). In the event of larger ulnar variances we prefer ulnar shortening osteotomy. The other techniques will be restricted to cases where the distal radio ulnar joint has been impaired. PMID:17361890

  5. The utility of MR imaging of the shoulder joint: comparison of the MR imaging between conventional MR imaging and arthrographic MR imaging

    International Nuclear Information System (INIS)

    To evaluate the diagnostic value of MRI of the shoulder. Between January and June 1997, shoulder MRI and arthroscopy were performed in a total of 48 patients with shoulder pain (n=3D30) or shoulder instability (n=3D18). Forty-five were males and three were females; their ages ranged from 16 to 67 (mean 32.5) years. The period between shoulder MRI and arthroscopy was between one and 390 (mean, 42.2) days. Twenty-six patents underwent MR arthrography (AMR), and 22 conventional MRI(CMR). Each image was analyzed for rotator cuff injury, glenoid labral injury, SLAP lesion, and biceps tendon injury. On arthroscopy, one disease was found in 34 patients, two were found in six, three diseases were found in seven, and one patient had four diseases. Arthroscopic diagnosis was as follows:rotator cuff injury, 29;SLAP lesion, 12;glenoid labral injury, 10;biceps tendon injury, 4;subacromial bursitis, 2;chronic synovitis, 1;adhesive capsulitis, 1;superior glenohumeral ligament injury, 1;normal, 1. For rotator cuff injury, the sensitivity of MRI was 65.5% and specificity was 93.0% (AMR:66.7%, 95.8%, CMR:65.2%, 86.4%). For SLAP lesion, sensitivity was 58.3% and specificity was 97.2% (AMR:66.7%, 100%, CMR:50%, 93.8%);for glenoid labral injury, sensitivity was 80.0% and specificity was 89.5% (AMR:85.7%, 84.2%, CMR:66.7%, 94.7%), and for biceps tendon injury, the false negative rate was 100%. In cases involving glenoid labral injury, the diagnostic accuracy of shoulder MRI was relatively high;in rotator cuff injury and SLAP lesion, however, diagnosis was limited, and in biceps tendon injury was difficult. We suggest, however, that MR arthrography has certain diagnostic advantages over conventional MRI.=20

  6. Reactive synovitis of the knee joint: MR imaging appearance with arthroscopic correlation

    International Nuclear Information System (INIS)

    Objective. To evaluate the use of routine MR imaging sequences in detecting and characterizing secondary reactive synovitis of the knee joint using arthroscopy as the standard of reference.Design and patients. Fifty consecutive patients with a history of knee pain who were referred for MR imaging and subsequently underwent arthroscopy of the knee comprised the study group. MR images were evaluated for the presence and appearance of synovitis reflected in synovial thickening and irregularity. Synovial thickening was graded on MR imaging as follows: 0=normal, 1=thin line of increased signal intensity, 2=increased signal intensity with frond-like or hair-like projections and a granular appearance of joint fluid. Standard knee imaging protocols were used.Results. The sensitivity, specificity, and accuracy of MR imaging in detecting synovitis compared with arthroscopy were 88%, 97%, and 95%, respectively. Grade 1 synovitis was best seen on proton-density-weighted images, demonstrating increased signal intensity of the synovium against the relatively low signal intensity of the joint fluid. Grade 2 synovitis was best seen on proton-density images and T2-weighted spin echo and fast spin echo images with fat saturation, demonstrating a granular and linear hair-like appearance of joint fluid. Axial and sagittal imaging planes were most helpful in the diagnosis of synovitis.Conclusion. Routine MR pulse sequences are useful in identifying the presence and extent of synovial abnormalities. The detection of different stages of synovial pathology should become an important part of the evaluation of the post-traumatic patient as treatment may be altered as a result. (orig.)

    Osteochondrosis lesions commonly occur on the femoral trochlear ridges in horses and radiography and ultrasonography are routinely used to diagnose these lesions. However, poor correlation has been found between radiographic and arthroscopic findings of affected trochlear ridges. Interobserver agreement for ultrasonographic diagnoses and correlation between ultrasonographic and arthroscopic findings have not been previously described. Objectives of this study were to describe diagnostic sensitivity and interobserver agreement of radiography and ultrasonography for detecting and grading osteochondrosis lesions of the equine trochlear ridges, using arthroscopy as the reference standard. Twenty-two horses were sampled. Two observers independently recorded radiographic and ultrasonographic findings without knowledge of arthroscopic findings. Imaging findings were compared between observers and with arthroscopic findings. Agreement between observers was moderate to excellent (κ 0.48-0.86) for detecting lesions using radiography and good to excellent (κ 0.74-0.87) for grading lesions using radiography. Agreement between observers was good to excellent (κ 0.78-0.94) for detecting lesions using ultrasonography and very good to excellent (κ 0.86-0.93) for grading lesions using ultrasonography. Diagnostic sensitivity was 84-88% for radiography and 100% for ultrasonography. Diagnostic specificity was 89-100% for radiography and 60-82% for ultrasonography. Agreement between radiography and arthroscopy was good (κ 0.64-0.78). Agreement between ultrasonography and arthroscopy was very good to excellent (κ 0.81-0.87). Findings from this study support ultrasound as a preferred method for predicting presence and severity of osteochondrosis lesions involving the femoral trochlear ridges in horses. PMID:23278908

    Full Text Available Introduction: Surgical excision of the ununited ossicles has been suggested for unresolved sequelae of Osgood-Schlatter disease in adults resistant to conservative measures. We report a case where arthroscopy was used to excise the ossicles. A bird eye view from the superolateral portal was helpful in the arthroscopic procedure for excision of the deep low lesion. Case Report: A 32-year-old, male driver had anterior knee pain during walking and sports activity that had been treated conservatively for 3 months. On physical examination, there was a prominent tibial tubercle, but without palpable pain. There was obvious pain when the knee was approaching full extension. On image, a huge ununited ossicle was seen behind the patellar tendon, intruding into the joint space, and there was another two small ununited ossicles beneath the bow-shaped patellar tendon. Arthroscopy was performed through a three portals technique, and a bird eye view was achieved from the superolateral portal. The ossicles were separated from the surrounding soft tissue with a motorized shaver. The small ununited ossicles were removed by use of a grasper. The huge ossicle was removed by use of a motorized bur, and the contouring of the irregular surface of the tibial tubercle was performed. After 3 months, the patient returned to sports activities without any restrictions. Conclusion: This report shows that a huge ossicle can cause impingement in anterior knee compartment, and it can be easily removed arthroscopically under assistance of an additional portal. Keywords: Osgood-Schlatter disease; Knee; Arthroscopy; Superolateral portal.

  10. The subscapularis: anatomy, injury, and imaging

    International Nuclear Information System (INIS)

    The subscapularis is the largest and most powerful of the rotator cuff muscles and fulfills an important role in glenohumeral movement and stability. The spectrum and implications of subscapularis muscle or tendon injury differ from injury to other rotator cuff components because of its unique structure and function. Diagnosing subscapularis injury is clinically difficult and assessment of subscapularis integrity may be limited during arthroscopy or open surgery. Diagnostic imaging plays an important part in diagnosing and evaluating the extent of subscapularis injury. The radiologist should be aware of the anatomy of the subscapularis, the variations in muscle or tendon injury, and the potential implications for treatment and prognosis. (orig.)

  11. Injury of the ligaments of the knee: Magnetic resonance evaluation

    International Nuclear Information System (INIS)

    To evaluation the value of MR imaging in the examination of ligament injury of the knee, we retrospectively analysed the MR images of 61 injured knees of 60 patients. The presence of tear was determined by arthroscopy in all caes. Anterio/posterior cruciate ligaments(ACL/PCL) were demonstrated by sagittal images. Medial/lateral collateral ligaments(MCL/ LCL) were evaluated on coronal images. The diagnostic accuracy were 91.8%, 96.7% and 100% for ACL, PCL and MCL, respectively. The specificity for the lateral collateral ligament was 100%. It is concluded that magnetic resonance imaging is an accurate method in detecting injury of the ligaments of the knee

  13. MRI in clinically questionable posttraumatic knee joint lesions

    International Nuclear Information System (INIS)

    An MRI examination was performed on 31 patients with clinically questionable posttraumatic knee joint lesions. A broad range of intra- and extraarticular pathological changes was found. The correlation of MRI with arthroscopy and surgery showed a correct MRI diagnosis in 78% of the meniscal lesions (n=18) and in 89% of the anterior cruciate ligament ruptures (n=9). An analysis of false positive and false negative MRI diagnoses was made. MRI offers the opportunity for noninvasive complex assessment of knee joint structures and is of particular value in the diagnosis of posttraumatic knee joint lesions. (orig.)

    The present study proposes a new MRI-specific staging of chondromalacia patellae (CMP) which is based on cartilage thickness decrease and signal intensity behaviour under compression as well as cartilage morphology in the plain image. The investigation was performed in 30 patients with varying knee complaints who underwent arthroscopy after MR imaging. It was demonstrated that three CMP stages can already be differentiated by MRI under compression in arthroscopically healthy cartilage. This proves a marked improvement in the early diagnosis of CMP.

  16. Is it possible to diagnose idiopathic chondropathia of the patella by radiological methods

    Energy Technology Data Exchange (ETDEWEB)

    Kaufmann, J.; Langlotz, M.

    1984-10-01

    In a retrospective study of 47 cases of chondromalacia proved by operation, a correct diagnosis had been made by arthrography in three cases. In 44 patients a false negative finding had been obtained. A prospective study was carried out comparing single and double contrast arthrography as well as double contrast arthrotomography and scintigraphy in ten patients with typical chondropathia. It was confirmed by arthroscopy in nine cases. Only two patients with severe chondromalacia showed abnormal findings by arthrography or scintigraphy. Our investigation has led to the conclusion that arthrography is not a suitable method for demonstrating idiopathic chondropathia of the patella.

    1982-06-01

    Sixtyseven patients with pain in the knee were studied. A computed tomography (CT) score indicating chondromalacia was devised, based on the results of CT after arthrography. This score takes account of the regularity, the congruity, and the imbibition of contrast material. Thus the patients could be divided into four groups: those who definitely have chondromalacia (++), probably (+), probably not (+-), and definitely not (-). These results were compared with the clinical diagnosis based on clinical signs, arthroscopy, or operation. Eighteen patients had clinically proved chondromalacia, CT scored 14++, 3+ and 1+-. Twentynine patients had no chondromalacia, CT scored 19-, 8+-, and 2+. Twenty patients had an uncertain clinical diagnosis. Arthrography was less accurate in detecting chondromalacia.

    Caggiano, Nicholas; Matullo, Kristofer S

    2014-01-01

    The scaphoid is stabilized by the scapholunate ligament (directly) and lunotriquetral ligament (indirectly). Disruption of either of these ligaments leads to a pattern of instability that, left untreated, leads to altered mechanics of the wrist and ultimately debilitating arthritis and collapse. Although arthroscopy remains the gold standard for diagnosis of these injuries, plain films and advanced imaging are useful adjuncts. In the acute setting, conservative treatment may be attempted, but recalcitrant cases require surgical stabilization. Salvage procedures are also available for those patients who fail initial stabilization or present with late degeneration. PMID:24267214

    To retrospectively evaluate the diagnostic accuracy of magnetic resonance (MR) arthrography of the hip with leg traction in the evaluation of ligamentum teres lesions and to evaluate whether there is increased articular distraction, possibly indicating secondary instability, in hips with ligamentum teres injuries. Institutional review board approval and informed consent were obtained for this retrospective study. MR arthrograms of the hip with leg traction of 184 consecutive patients, including 108 men (mean age, 32.6 years; range, 19-53 years) and 76 women (mean age, 38.5 years; range, 18-56 years), who underwent hip arthroscopy were assessed for the presence of ligamentum teres lesions. The MR arthrographic findings were independently assessed by two radiologists who were blinded to the arthroscopic results. The inclusion criteria stipulated no previous surgery, arthroscopy within 1 month after MR arthrography, and availability of a detailed surgical report with ligamentum teres findings. The arthroscopy findings served as the reference standard. Sensitivity, specificity, accuracy, and K statistics for interobserver and intraobserver agreement were calculated. At arthroscopy, 32 ligamentum teres injuries were found. The ligamentum teres was normal in 152 (82.6 %) patients and had suffered low-grade partial tears in 15 (8.1 %) patients, high-grade partial tears in 10 (5.4 %) patients, and complete ruptures in 7 (3.8 %) patients. MR arthrography with axial traction demonstrated moderate sensitivity and high specificity for both low-grade (62/93 %) and high-grade (66/96 %) partial tears. Grouping low- and high-grade partial tears increased the diagnostic performance of MR arthrography, yielding a sensitivity of 87 % and a specificity of 95 %. For complete ligamentum teres tears, MR arthrography with leg traction demonstrated high sensitivity (92 %) and specificity (98 %). Articular distraction was significantly increased in patients with complete ruptures of the

    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.

    2011-10-01

    Contrary to general belief, arthroscopic assisted reduction in distal radius fractures can be done in an expeditious manner and with minimal consumption of operating room resources. This article presents the steps for a pleasant arthroscopic experience in detail. The technique proposed combines the benefits of rigid fixation with volar locking plates (for the extra-articular component) and arthroscopic control of the reduction (for the articular component). It is important that the operation be carried out using the dry arthroscopic technique. However, arthroscopy is just an addition to conventional methods. Thorough knowledge of and facility with classic techniques of distal radius fracture treatment is essential for a good result. PMID:21971058

    The prevalence of ligamentous injury associated with fractures of the distal radius is reported to be as high as 69% with injury to the scapholunate interosseous ligament and lunotriquetral interosseous ligament occurring in 16% to 40% and 8.5% to 15%, respectively. There is a lack of consensus on which patients should undergo advanced imaging, arthroscopy, and treatment and whether this changes their natural history. Overall, patients with high-grade intercarpal ligament injuries are shown to have longer-term disability and sequelae compared with those with lower-grade injuries. This article reviews the diagnosis and treatment options for these injuries. PMID:26205702

    Ganglion cyst is the most common soft tissue tumour of hand. Sixty to seventy percent of ganglion cysts are found in the dorsal aspect of the wrist. They may affect any age group; however they are more common in the twenties to forties. Its origin and pathogenesis remains enigmatic. Non-surgical treatment is unreliable with a high recurrence rates. Open surgical excision leads to unsightly scar and poor outcome. Arthroscopy excision has shown very promising result with very low recurrence rate. We reviewed the current literature available on dorsal wrist ganglion. PMID:25983472

    The aetiology of painful dorsal wrist ganglia remains obscure. In a prospective study we investigated the link between a painful dorsal wrist ganglion and wrist joint abnormality with wrist arthroscopy before excision of the ganglion. Of 16 wrists arthroscoped 12 were abnormal, 10 had an abnormal scapholunate joint, and two had abnormal lunatetriquetral joints. We think that painful dorsal wrist ganglia, like popliteal cysts in the knee, are markers of underlying joint abnormalities. Surgeons who treat painful ganglia should be aware of a possible underlying cause so that they can target treatment more accurately, particularly in recurrent cases and those patients with persistent wrist pain after excision of the ganglion.

    The subscapularis is the largest and most powerful of the rotator cuff muscles and fulfills an important role in glenohumeral movement and stability. The spectrum and implications of subscapularis muscle or tendon injury differ from injury to other rotator cuff components because of its unique structure and function. Diagnosing subscapularis injury is clinically difficult and assessment of subscapularis integrity may be limited during arthroscopy or open surgery. Diagnostic imaging plays an important part in diagnosing and evaluating the extent of subscapularis injury. The radiologist should be aware of the anatomy of the subscapularis, the variations in muscle or tendon injury, and the potential implications for treatment and prognosis. (orig.)

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

    A three-year-old male greyhound was presented with acute onset right forelimb lameness because of medial displacement of the biceps tendon of origin. Ultrasonographic examination confirmed the diagnosis, and a concomitant partial tear of the medial glenohumeral ligament was detected during arthroscopy. To stabilise the biceps tendon, polypropylene mesh was fixed across the intertubercular groove to replace the torn transverse humeral retinaculum. Recovery was uneventful and lameness resolved. Fifteen months later, the dog was presented with medial displacement of the biceps tendon of origin of the left shoulder, and was treated successfully using the same technique. PMID:23614688

  11. Usefulness of MR arthrography of the hip with leg traction in the evaluation of ligamentum teres injuries

    To retrospectively evaluate the diagnostic accuracy of magnetic resonance (MR) arthrography of the hip with leg traction in the evaluation of ligamentum teres lesions and to evaluate whether there is increased articular distraction, possibly indicating secondary instability, in hips with ligamentum teres injuries. Institutional review board approval and informed consent were obtained for this retrospective study. MR arthrograms of the hip with leg traction of 184 consecutive patients, including 108 men (mean age, 32.6 years; range, 19-53 years) and 76 women (mean age, 38.5 years; range, 18-56 years), who underwent hip arthroscopy were assessed for the presence of ligamentum teres lesions.

    Full Text Available Background: Arthroscopy of the great toe MTP joint has been practiced with favourable outcomes. A range of indications have been described ranging from synovitis to osteochondral defects. The purpose of the present study was to describe our technique and to assess the functional outcome following arthroscopic management of Hallux MTP disorders using AOFAS scoring system. Methods: We describe the technique of Hallux MTP joint arthroscopy in twenty patients. Indications included hallux rigidus with osteophytes, chondromalacia, OCDs, loose bodies, arthrofibrosis, synovitis, tophaceous gout arthritis and intra-articular fractures of MTP joint. All patients had been evaluated clinically and radiologically with record of their AOFAS scores pre-operatively. At a minimum follow-up of two years the clinical assessment was carried out with AOFAS scores. Results: The mean pre-operative and post-operative AOFAS score were 47 (range 10-78 and 97 (87 -100 respectively. The patient with intra-articular fracture had an excellent outcome following arthroscopic reduction of the fracture. Conclusion: Arthroscopic management of painful hallucial MTP joint is a specialized technique, which if performed for the right indications, gives a favourable outcome with minimal complications.

  14. Which oblique plane is more helpful in diagnosing an anterior cruciate ligament tear?

    International Nuclear Information System (INIS)

    Aim: To evaluate the diagnostic role of additional oblique coronal and oblique sagittal magnetic resonance imaging (MRI) for an anterior cruciate ligament (ACL) tear. Materials and methods: A total of 101 patients who had undergone preoperative knee MRI examinations with orthogonal and two sets of oblique images were enrolled in the study. Two radiologists evaluated the MRI images by the use of four methods: orthogonal images only (method A); orthogonal and additional oblique coronal images (method B); orthogonal and oblique sagittal images (method C); and orthogonal images with oblique coronal and sagittal images (method D). The status of the ACL (normal or tear) was determined by consensus. The sensitivity, specificity, and accuracy for an ACL tear with the use of each method were calculated in comparison with arthroscopy as the reference standard, and values were statistically analysed using the McNemar test. The diagnostic accuracies were compared using receiver operating characteristic (ROC) analysis. Results: Arthroscopy identified 10 partial ACL tears and 30 complete ACL tears. The specificities and accuracies for methods B, C, and D were significantly higher than the specificities and accuracies for method A (p 0.05). Conclusions: Additional oblique imaging for an ACL tear improved the specificity. Either of the oblique imaging methods is sufficient, and no further improvement in the diagnostic efficacy was achieved by simultaneous use

    Since its inception, arthroscopic surgery has become widely adopted among orthopedic surgeons. It is therefore important to have an understanding of the basic principles of arthroscopy. Compared with open techniques, arthroscopic procedures are associated with smaller incisions, less structural damage, improved intra-articular visualization, less pain in the immediate postoperative period, and faster recovery for patients. Pump systems used for arthroscopic surgery have evolved over the years to provide improved intraoperative visualization. Gravity flow systems were described first and are still commonly used today. More recently, automated pump systems with pressure or dual pressure and volume control have been developed. The advantages of automated irrigation systems over gravity irrigation include a more consistent flow, a greater degree of joint distention, improved visualization especially with motorized instrumentation, decreased need for tourniquet use, a tamponade effect on bleeding, and decreased operative time. Disadvantages include the need for additional equipment with increased cost and maintenance, the initial learning curve for the surgical team, and increased risk of extra-articular fluid dissection and associated complications such as compartment syndrome. As image quality and pump systems improve, so does the list of indications including diagnostic and treatment modalities to address intra-articular pathology of the knee, shoulder, hip, wrist, elbow, and ankle joints. This article reviews the current literature and presents the history of arthroscopy, basic science of pressure and flow, types of irrigation pumps and their functions, settings, applications, and complications.

    The purpose of this study was to evaluate and review the diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of imaging diagnosis for temporomandibular disorders. The role of diagnostic imaging is to detect and document specific anatomic abnormalities associated with the signs and symptoms in the temporomandibular joint. Magnetic resonance imaging (MR imaging) can accurately depict disc displacement and disc deformity. MR imaging is our first choice among the various imaging modalities for the patients with clinical signs and symptoms. However, it has been shown that intra-capsular adhesions and perforations of the disc and retrodiscal tissue are sometimes not detected by MR imaging. To improve the diagnostic technique for adhesions and perforations, double-contrast arthrotomography with fluoroscopy should be employed. The irregular surface of the eminences and the glenoid fossae shown by MR imaging and tomography are correlated with subchondral bone exposure by arthroscopy. Erosion of the condyles detected by MR imaging, tomography and rotational panoramic radiography is correlated with subchondral bone exposure detected by arthroscopy. (author). 69 refs.

    International Nuclear Information System (INIS)

    Objective: To evaluate the diagnostic value of X-ray and MRI of avulsion fracture in tibial intercondylar eminence. Methods: X-ray and MRI images of 32 patients with avulsion fracture in tibial intercondylar eminence were retrospectively analyzed. All the cases were confirmed by arthroscopy. X-ray examinations were obtained from a standard anteroposterior and lateral views, part of them with oblique views. Axial FSE-T2WI, sagittal SE-T1WI, FSE-T2WI, STIR and coronal FSE-T2WI, GRE-STIR were examined in MRI examinations. Results: X-ray showed 28 correct diagnoses (87.5%) and 4 occult fracture misdiagnosis (12.5%), however, all the cases were correctly diagnosed with MRI (100%). In the patients which were correctly diagnosed by X-ray, MRI showed other lesions of knee joints (28/28), including 26 cases cruciate ligament trauma, 7 cases meniscus trauma, 4 cases collateral ligament trauma, 26 cases bone-contusion, and 6 cases other fracture. In the patients which were missed diagnoses in X-ray examinations, 3 cases showed cruciate ligament trauma, 1 case showed meniscus trauma, and 2 cases showed bone-contusion in MRI. Conclusion: Avulsion fracture in tibial intercondylar eminence were often associated with other knee joints lesions, which can be treated by arthroscopy directly if they were diagnosed by X-ray examinations. However, occult fractures should be examined by MRI, which can offer detailed information for clinic treatment. (authors)

    Full Text Available : In today’s world high velocity road traffic accidents, sports activities and increased fitness awareness, ACL injuries is a common clinical problem. Once upon a time ACL rupture led to a relatively safe existence and was thought to be of less significance. Now with improved knee kinematics and clinical skills, it has been established that post ACL injury, the prevalence of clinically significant meniscal damage increases with time and is associated with increasing disability and arthrosis. Ligament reconstruction has not been shown to prevent arthrosis, but studies show that it appears to reduce the risk of subsequent meniscal injury and improve anteroposterior knee motion and facilitates return to high level sporting activities. As surgical techniques like Arthroscopy improve the ability to tackle complex problems, complex decisions regarding Meniscal repair and transplantation, Cartilage repair and regeneration are now commonplace, as are decisions regarding the need for Osteotomies in Arthritically unstable knees. Arthroscopic reconstruction of the Anterior Cruciate Ligament with patellar bone - tendon - bone graft is minimally invasive and is relatively quick and simple to perform, although attention to detail as required for good results. Thus arthroscopy helps in diagnosis and treatment of internal derangement and on extra articular reconstruction.

    Full Text Available Abstract Background Magnetic resonance (MR imaging is a useful diagnostic tool for the assessment of knee joint injury. Anterior cruciate ligament repair is a commonly performed orthopaedic procedure. This paper examines the concordance between MR imaging and arthroscopic findings. Methods Between February, 1996 and February, 1998, 48 patients who underwent magnetic resonance (MR imaging of the knee were reported to have complete tears of the anterior cruciate ligament (ACL. Of the 48 patients, 36 were male, and 12 female. The average age was 27 years (range: 15 to 45. Operative reconstruction using a patellar bone-tendon-bone autograft was arranged for each patient, and an arthroscopic examination was performed to confirm the diagnosis immediately prior to reconstructive surgery. Results In 16 of the 48 patients, reconstructive surgery was cancelled when incomplete lesions were noted during arthroscopy, making reconstructive surgery unnecessary. The remaining 32 patients were found to have complete tears of the ACL, and therefore underwent reconstructive surgery. Using arthroscopy as an independent, reliable reference standard for ACL tear diagnosis, the reliability of MR imaging was evaluated. The true positive rate for complete ACL tear diagnosis with MR imaging was 67%, making the possibility of a false-positive report of "complete ACL tear" inevitable with MR imaging. Conclusions Since conservative treatment is sufficient for incomplete ACL tears, the decision to undertake ACL reconstruction should not be based on MR findings alone.

    This report describes the treatment of 2 cases of full-thickness cartilage defect of the femoral head. The authors performed osteochondral autologous transplantation with a different technique that has not been reported to date. One patient was 37 years old, and the other was 42 years old. Both presented with hip pain. In both patients, radiograph and magnetic resonance imaging scan showed a focal chondral defect on the weight-bearing area of the femoral head and acetabular impingement. A retrograde osteochondral autologous transplantation technique combined with hip arthroscopy and arthroscopic impingement treatment was performed. After a 2-month recovery period, the symptoms were resolved. In the first year of follow-up, Harris Hip scores improved significantly (case 1, 56.6 to 87.6; case 2, 58.6 to 90). The technique described yielded good short- and midterm clinical and radiologic outcomes. To the authors' knowledge, this report is the first to describe a retrograde osteochondral transplantation technique performed with hip arthroscopy in the femoral head. PMID:24972445

    A 44-year-old woman presented following minor trauma to her right knee. While dancing she externally rotated around a planted foot and felt sudden pain in her right knee. She presented with her knee locked in extension with a “dorsal fin” appearance of the soft tissues tented over the patella. This was diagnosed as a rare case of an intraarticular patella dislocation, which was rotated 90 degrees about the vertical axis. Closed reduction in the emergency room was unsuccessful but was achieved in theatre under general anaesthetic with muscle relaxation. Postreduction arthroscopy demonstrated that no osteochondral or soft tissue damage to the knee had been sustained. In patients presenting with a knee locked in extension with tenting of skin over the patella (the “dorsal fin” appearance), intra-articular patella dislocation should be suspected. Attempts to reduce vertical patella dislocations under sedation with excessive force or repeatedly without success should be avoided to prevent unnecessary damage to the patellofemoral joint. In this clinical situation we recommend closed reduction under general anaesthetic followed by immediate knee arthroscopy under the same anaesthetic to ensure that there is no chondral damage to the patella or femoral trochlea and to rule out an osteochondral fracture.

    To investigate the diagnostic accuracy of oblique axial intermediate weighting MR imaging in detecting partial thickness anterior cruciate ligament (ACL) bundle tears. The study protocol was approved by the institutional ethics committee. Sixty-one subjects (43 male, 18 female; mean age 27.4 years; range 9 to 57 years) with clinically suspected ACL tear or meniscal tear between September 2009 and January 2011 were studied with MRI and arthroscopy. Detection of partial tear for the ACL as a whole and for each ACL bundle by protocol A (standard orthogonal sequences) and protocol B (standard orthogonal sequences plus oblique axial intermediate weighted imaging) was compared in a blinded fashion. Performance characteristics for protocol A and protocol B were compared using sensitivity, specificity, accuracy and ROC curves. A two-tailed p value of <0.05 indicated statistical significance. Fifteen (24.6%) normal, 15 (24.6%) partial and 31 complete tears were diagnosed by arthroscopy. Sensitivity, specificity and accuracy of protocol A for the diagnosis of partial tear of the ACL was 33%, 87% and 74%, while for protocol B the values were 87%, 87% and 87% respectively. The area under the curve (AUC) for the diagnosis of partial ACL tear and individual bundle tear was higher for protocol B, although this difference did not reach statistical significance (p > 0.05). The addition of oblique axial imaging to standard MR imaging improves diagnostic accuracy for detecting partial tears of the ACL as well as individual bundle tears of the ACL. (orig.)

    To evaluate the differential features of complete and partial-thickness tears of the posterior cruciate ligament (PCL) and to describe associated knee injuries at magnetic resonance imaging (MRI). Twenty-four subjects were studied, including 15 with complete PCL tears and 9 with partial PCL tears. The PCL status was determined at arthroscopy in all cases. Knee MRI were performed at 1.0 Tesla using a dedicated knee surface coil. Two radiologists retrospectively reviewed MR images and correlated MRI findings to results of arthroscopy. There was no statistically significant difference between complete tears and partial tears with regard to thickness, margination, and signal intensity of the PCL. However, complete tears were more likely to show focal areas of ligamentous discontinuity (13/15: 3/9, {rho} = 0.0073). Associated knee injuries were seen in 22 (92%) patients and were seen more frequently in patients with complete PCL tears, which were bony injuries (n 16, 67%), tears of the medial collateral ligament (n = 12, 50%) and menisci (n = 11, 46%), and stage III joint effusion (n = 17, 71%). The most useful MRI criteria for distinguishing complete from partial PCL tear is focal area of ligamentous discontinuity, that is complete tears are more likely to show focal areas of discontinuity, whereas partial tears are more likely to show at least some intact fibers.

    Objective To compare the diagnostic performance of the three-dimensional turbo spin-echo (3D TSE) magnetic resonance imaging (MRI) technique with the performance of the standard two-dimensional turbo spin-echo (2D TSE) protocol at 1.5 T, in the detection of meniscal and ligament tears. Materials and Methods Thirty-eight patients were imaged twice, first with a standard multiplanar 2D TSE MR technique, and then with a 3D TSE technique, both in the same 1.5 T MRI scanner. The patients underwent knee arthroscopy within the first three days after the MRI. Using arthroscopy as the reference standard, we determined the diagnostic performance and agreement. Results For detecting anterior cruciate ligament tears, the 3D TSE and routine 2D TSE techniques showed similar values for sensitivity (93% and 93%, respectively) and specificity (80% and 85%, respectively). For detecting medial meniscal tears, the two techniques also had similar sensitivity (85% and 83%, respectively) and specificity (68% and 71%, respectively). In addition, for detecting lateral meniscal tears, the two techniques had similar sensitivity (58% and 54%, respectively) and specificity (82% and 92%, respectively). There was a substantial to almost perfect intraobserver and interobserver agreement when comparing the readings for both techniques. Conclusion The 3D TSE technique has a diagnostic performance similar to that of the routine 2D TSE protocol for detecting meniscal and anterior cruciate ligament tears at 1.5 T, with the advantage of faster acquisition.

    Magnetic resonance findings with clinical and arthroscopic correlation of intraligamentous cysts of the anterior cruciate ligament (ACL) are presented. Three cases of intraligamentous cysts of the ACL were identified out of 681 knee MRI examinations over a 2-year period. Arthroscopy and postoperative MRI were performed in all three patients, each of whom experienced knee pain with extreme flexion and extension. In all three cases the intraligamentous cyst was homogeneously hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging relative to the ACL. Two of the three ACL cysts required a 70{degrees} scope for adequate visualization and establishment of posteromedial and posterolateral portals for arthroscopic treatment. One cyst could not be visualized arthroscopically and probing of the ACL from the anterior portal resulted in drainage of the cyst. No patient had presence of ACL cyst on follow-up MRI or recurrence of symptoms at a mean of 24 months. Intraligamentous cyst of ACL is a rare cause of knee pain. It should be suspected in patients having chronic pain with extremes of motion. Magnetic resonance findings are diagnostic and help to guide arthroscopy. 14 refs., 3 figs.

  7. Diognostic accuracy of MR imaging and pattern of injury in the posterior cruciate ligament injury

    International Nuclear Information System (INIS)

    To evaluate the diagnostic accuracy of MR imaging in posterior cruciate ligament(PCL) injuries, to describe the variety of these injuries and to assess the type and frequency of associated knee injuries. We retrospetively analysed 75 cases with knee injuries. In all cases, the presence of a PCL tear was determined by arthroscopy or surgery and the type of tear and patterns of associated knee injuries were described. Twenty-eight PCL tears were identified with arthroscopy or surgery. Figures for the sensitivity, specificity, and accuracy of MR diagnosis for the PCL injury were 86%, 94% and 91% respectively. Twenty-one cases(75%) had complete PCL tears and seven (25%) had partial tears. The commonest tear site was midsubstance(18 cases, 64.3%). Twenty-seven cases(96%) had associated knee injuries ; the remaining patient (4%) had isolated PCL injuries, There were 19 cases(68%) of ligamentous injuries, ten(36%) of meniscal tear, ten (36%) of bony injuries, and 20 (71%) of joint effusions. Of the ligamentous injuries, those involving the medial collateral ligament were most often seen(10 cases, 36%). MR imaging is an accurate method for the detection and evaluation of PCL injury and associated knee abnormalities

  8. Complete versus partial-thickness tears of the posterior cruciate ligament: differential features at MR imaging

    International Nuclear Information System (INIS)

    To evaluate the differential features of complete and partial-thickness tears of the posterior cruciate ligament (PCL) and to describe associated knee injuries at magnetic resonance imaging (MRI). Twenty-four subjects were studied, including 15 with complete PCL tears and 9 with partial PCL tears. The PCL status was determined at arthroscopy in all cases. Knee MRI were performed at 1.0 Tesla using a dedicated knee surface coil. Two radiologists retrospectively reviewed MR images and correlated MRI findings to results of arthroscopy. There was no statistically significant difference between complete tears and partial tears with regard to thickness, margination, and signal intensity of the PCL. However, complete tears were more likely to show focal areas of ligamentous discontinuity (13/15: 3/9, ρ = 0.0073). Associated knee injuries were seen in 22 (92%) patients and were seen more frequently in patients with complete PCL tears, which were bony injuries (n 16, 67%), tears of the medial collateral ligament (n = 12, 50%) and menisci (n = 11, 46%), and stage III joint effusion (n = 17, 71%). The most useful MRI criteria for distinguishing complete from partial PCL tear is focal area of ligamentous discontinuity, that is complete tears are more likely to show focal areas of discontinuity, whereas partial tears are more likely to show at least some intact fibers

    Introduction: Intra-articular ganglion cysts of the knee joint are rare occurrences. They are usually encountered as incidental findings in magnetic resonance imaging (MRI), or in arthroscopy. They may originate from both the cruciate ligaments and the menisci, from the popliteus tendon and alar folds, infrapatellar fat pad of Hoffa, and subchondral bone cysts. Those arising from the Hoffa’s fat pad, usually present as palpable mass at anterior aspect of the knee joint. We report a case of intraarticular ganglion cyst of knee arising from the infrapatellar fat pad and protruding anterolaterally through retinacular rent into the subcutaneous plane. Case Report: A 19-year-old young man, presented with a painless gradually increasing swelling at the anterior aspect of left knee of 9 months duration. MRI scan revealed a multilobulated, cyst with septations within the anterior aspect of the knee joint, just inferolateral to the patella, with deep extension into the infrapatellar fat pad, and superficial extension into the subcutaneous space across the retinaculum. After diagnostic arthroscopy, we performed an open excision of the cystic mass and confirmed the retinacular rent pre-operatively. Conclusion: Arthroscopic resection and debridement is the gold standard treatment in ganglion cyst of the knee. However, a subcutaneous extension may lead to incomplete arthroscopic resection: Leaving behind the residual tissue which may cause recurrence. Therefore, proper pre-operative evaluation of MR images of these cases is very important. PMID:27299075

  11. Magnetic resonance tomography (MRT) of the knee joint: Meniscus, cruciate ligaments and hyaline cartilage

    International Nuclear Information System (INIS)

    The use of MRT for diagnosing injury to the meniscus, the cruciate ligaments and hyaline cartilage was evaluated retrospectively in 82 knee joints without any knowledge of operative findings. In 49 cases the results were verified by arthroscopy and in 33 cases by arthrotomy. Sensitivity, specificity and diagnostic accuracy of MRT for meniscus lesions was 73.9%, 96.9%, and 94.6%. Corresponding values for lesions of the anterior cruciate ligament were 88.9%, 96.6%, and 94.7%, and for lesions of the hyaline cartilage 62.6%, 96.1%, and 87.9%, respectively. In addition to its high specificity, MRT proved accurate in excluding lesions of the meniscus (97.1%) of the anterior cruciate ligament (96.6%) and of hyaline cartilage (88.8%). A negative finding on MRT therefore makes the presence of a lesion of the meniscus, cruciate ligaments of cartilage unlikely. In such cases one is justified in delaying the use of arthroscopy or arthrotomy. (orig.)

    Full Text Available Background: Factors influencing publication of manuscripts in reputed journals have never been studied to the best of our knowledge. This study was conducted to evaluate the trend in publication within the Indian Journal of Orthopaedics (IJO. Materials and Methods: A cross-sectional study was conducted by accessing the online database of the IJO. All the issues available online were included. Published articles were classified into one of the following thirteen categories: (i Basic Sciences (ii trauma (upper limb and lower limb (iii infections (iv pediatric orthopedics (v arthroplasty (vi arthroscopy (vii spine surgery (viii musculoskeletal oncology (ix hand and microvascular surgery (x adult reconstruction (including the Ilizarov technique (xi general orthopedics and miscellaneous (xii letter to editor (xiii book review. A scatter diagram was plotted to study the individual trends. Results: A total of 2213 articles from 110 issues published between 1967 and 2014 were studied. Total number of articles per issue have increased over the years. Publications in the fields of trauma, adult reconstruction, arthroscopy and hand and microvascular surgery have increased steadily. Arthroplasty and spine surgery have recorded dramatic increase in publication. On the other hand, publications in the rest of the fields have declined of which the greatest fall is noted in the field of musculoskeletal oncology. Conclusions: Trend in publication with the IJO has changed over years with more articles being published in arthroplasty and Spine surgery. Despite advances, publication in the field of musculoskeletal oncology has fallen.

  13. Magnetic resonance imaging of meniscal bucket-handle tears

    International Nuclear Information System (INIS)

    To define MR signs of meniscal bucket-handle tears and evaluate the diagnostic efficiency of this technique. Retrospective study of 30 patients with a meniscal bucket-handle tear and 30 with a different type of tear, all proven by arthroscopy. The following MR signs of a bucket-handle tear were evaluated: 'separate meniscal fragment, 'double posterior cruciate ligament', 'snake sign' and 'double anterior horn'. A correct diagnosis of a bucket-handle tear was only made in 18/30 of patients. Several of the MR signs were seen in the same patient in 17 cases. A double posterior cruciate ligament was present only in cases of medial meniscus tears. The 12 menisci without these signs, and therefore not diagnosed as bucket-handle tears, were all classified as meniscal tears on the basis of signal extending to the meniscal surface. Nine of these were not displaced into the inter-condylar notch at arthroscopy. The interobserver agreement was excellent: kappa 0.88. The diagnosis of a bucket-handle meniscal tear, if it is displaced, can be made when one or more of the four MR evaluated signs are present. Other forms of meniscal tears are only exceptionally diagnosed as bucket-handle tears. (authors)

  14. Magnetic resonance imaging for the diagnosis of chondral, meniscal and cruciate ligaments injuries of the knee

    International Nuclear Information System (INIS)

    Objective: To evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) of the knee. Materials and methods: Seventy-two patients have been submitted to MRI previously to arthroscopy of the knee performed by a single surgeon and utilized as a comparative standard method. Sensitivity, specificity, values of likelihood and rate of interobserver agreement have been evaluated. Results: The kappa agreement coefficient between MRI and arthroscopy was very good for lesions in the anterior cruciate ligament (0.84), good for lateral meniscus (0.75), reasonable for medial meniscus (0.50) and poor for chondral lesions (< 0.50). MRI has demonstrated high sensitivity for tears in the anterior cruciate ligament (94%) and in the medial meniscus (92%), good sensitivity for lesions in the lateral meniscus (80%), and low sensitivity for lesions in all of the chondral zones (< 50%), while the specificity has been excellent for all the chondral, and ligamentous structures, besides the lateral menisci analyzed (more than 97%), and reasonable (65%) for the medial meniscus. Conclusion: MRI is an useful tool in the clinical diagnosis of intra-articular knee lesions, as already demonstrated by similar results reported both in the Brazilian and international literature.

    To assess diagnostic performance of traction MR arthrography of the hip in detection and grading of chondral and labral lesions with arthroscopic comparison. Seventy-five MR arthrograms obtained ± traction of 73 consecutive patients (mean age, 34.5 years; range, 14-54 years) who underwent arthroscopy were included. Traction technique included weight-adapted traction (15-23 kg), a supporting plate for the contralateral leg, and intra-articular injection of 18-27 ml (local anaesthetic and contrast agent). Patients reported on neuropraxia and on pain. Two blinded readers independently assessed femoroacetabular cartilage and labrum lesions which were correlated with arthroscopy. Interobserver agreement was calculated using κ values. Joint distraction ± traction was evaluated in consensus. No procedure had to be stopped. There were no cases of neuropraxia. Accuracy for detection of labral lesions was 92 %/93 %, 91 %/83 % for acetabular lesions, and 92 %/88 % for femoral cartilage lesions for reader 1/reader 2, respectively. Interobserver agreement was moderate (κ = 0.58) for grading of labrum lesions and substantial (κ = 0.7, κ = 0.68) for grading of acetabular and femoral cartilage lesions. Joint distraction was achieved in 72/75 and 14/75 hips with/without traction, respectively. Traction MR arthrography safely enabled accurate detection and grading of labral and chondral lesions.

    Objectives: In the present work, we aim to identify changes in the cartilage texture of the injured knee in young, physically active, patients by computer analysis of MRI images based on 3.0 T morphological sequences. Methods: Fifty-three young patients with training injury or trauma in one knee underwent MRI and arthroscopy. Textural features were computed from the MRI images of the knee-cartilages and two classes were formed of 28 normal and 16 with pathology only in the medial femoral condyle (MFC) cartilage. Results: Textural features with statistically significant differences between the two classes were found only at the MFC and the medial tibial condyle (MTC) areas. Three features-combinations, at the MFC or the MTC, maximized the between classes separation, thus, rendering alterations in cartilage texture due to injury more evident. The MFC cartilage in the pathology class was found more inhomogeneous in the distribution of gray-levels and of lower texture anisotropy and the opposed MTC cartilage, though normal on MRI and arthroscopy, was found to have lower texture anisotropy than cartilage in the normal class. Conclusion: Texture analysis may be used as an adjunct to morphological MR imaging for improving the detection of subtle cartilage changes and contributes to early therapeutic approach.

  18. Prospective comparison of 3D FIESTA versus fat-suppressed 3D SPGR MRI in evaluating knee cartilage lesions

    International Nuclear Information System (INIS)

    Aim: To prospectively compare the accuracy of three-dimensional fast imaging employing steady-state acquisition (3D FIESTA) sequences with that of fat-suppressed three-dimensional spoiled gradient-recalled (3D SPGR) in the diagnosis of knee articular cartilage lesions, using arthroscopy as the reference standard. Materials and methods: Fifty-eight knees in 54 patients (age range 21-82 years; mean 36 years) were prospectively evaluated by using sagittal 3D FIESTA and sagittal fat-suppressed 3D SPGR sequences. Articular cartilage lesions were graded on MRI and during arthroscopy with a modified Noyes scoring system. Sensitivity, specificity, and accuracy were assessed. Interobserver agreement was determined with κ statistics. Results: The performance of 3D FIESTA sequences (sensitivity, specificity, and accuracy were 80, 94, and 92%, respectively, for reader 1 and 76, 94, and 90%, respectively, for reader 2) was similar to that of fat-suppressed 3D SPGR sequences (sensitivity, specificity, and accuracy were 82, 92, and 90%, respectively, for reader 1 and 82, 90, and 88%, respectively, for reader 2) in the detection of knee articular cartilage lesions. The interobserver agreement varied from fair to good to excellent (kappa values from 0.43-0.83). Conclusion: 3D FIESTA has good diagnostic performance, comparable with fat-suppressed 3D SPGR in evaluating knee cartilage lesions, and it can be incorporated into routine knee MRI protocols due to the short acquisition time.

  19. Patella Dislocation with Vertical Axis Rotation: The “Dorsal Fin” Patella

    Full Text Available A 44-year-old woman presented following minor trauma to her right knee. While dancing she externally rotated around a planted foot and felt sudden pain in her right knee. She presented with her knee locked in extension with a “dorsal fin” appearance of the soft tissues tented over the patella. This was diagnosed as a rare case of an intraarticular patella dislocation, which was rotated 90 degrees about the vertical axis. Closed reduction in the emergency room was unsuccessful but was achieved in theatre under general anaesthetic with muscle relaxation. Postreduction arthroscopy demonstrated that no osteochondral or soft tissue damage to the knee had been sustained. In patients presenting with a knee locked in extension with tenting of skin over the patella (the “dorsal fin” appearance, intra-articular patella dislocation should be suspected. Attempts to reduce vertical patella dislocations under sedation with excessive force or repeatedly without success should be avoided to prevent unnecessary damage to the patellofemoral joint. In this clinical situation we recommend closed reduction under general anaesthetic followed by immediate knee arthroscopy under the same anaesthetic to ensure that there is no chondral damage to the patella or femoral trochlea and to rule out an osteochondral fracture.

    Full Text Available Mainly by a limited access to new techniques and technologies, veterinary medicine in developing countries, has been far behind from the human medicine. One of the causes is the limited access to technology and specific techniques. Moreover, it is clear that many new technologies have proven their benefits in the two disciplines, making necessary and almost mandatory their massive implementation in humans and animals. The possibility to use human elements for veterinary techniques would improve the technology access and veterinarians training, at lower costs. The purpose of this study is to verify the feasibility to perform a knee arthroscopy in dogs with small human joints arthroscopic lenses. Under protocols established in veterinary 12 knee arthroscopies were performed in canine cadaver, using a wrist and ankle arthroscope human of 2.4 mm in diameter and 30° of angulation. All the structures reported in the literature were possible to visualize using a 2.4 mm arthroscope. In this sense, it is possible to develop training activities and subsequent implementation of endoscopic techniques in canine femorotibiopatellar joint, using a lens of small joints of human medicine.

    Full Text Available BACKGROUND: Many different methods have been used in an effort to provide adequate analgesia after knee arthroscopic surgery. In this study analgesic effect of intra-articular fentanyl, pethidine and dexamethasone was compared. METHODS: In a double blind randomized study 48 male patients undergoing knee arthroscopic meniscectomy were allocated to groups receiving intra-articular fentanyl 50 µg or pethidine 20 mg or dexamethasone 8 mg at the end of arthroscopy during general aesthesia. Postoperative pain scores using visual analogue scale were measured and also analgesic requirements and the time of ability to walk were recorded. RESULTS: Pain scores at one, two, six and 24 h after intra-articular injection were not significantly different for fentanyl and pethidine but were higher significantly for dexamethasone at all four mentioned times. The mean average time of ability to walk was significantly longer for dexamethasone. The analgesic requirements during the first 24 h after intraarticular injection were significantly greater only for dexamethasone too. CONCLUSION: Better postoperative analgesia, less pain score and shorter time to walk were achieved by fentanyl and pethidine in comparison to dexamethasone but the results were not significantly different between fentanyl group and pethidine. KEYWORDS: Arthroscopy, opioid, pain.

    Purpose: To evaluate the diagnostic accuracy and indications of arthrography with Multidetector Computed Tomography (arthro-MDCT) of the wrist in patients with absolute or relative contraindications to magnetic resonance imaging (MRI) studies and in patients with periarticular metal implants using diagnostic arthroscopy as the gold standard. Materials and methods: After intra-articular injection of iodixanol and volumetric acquisition, 43 wrists in patients of both genders (18 females, 25 males, age range 32-60 years) were examined with a 16-detector-row CT scanner. Fifteen patients had prior wrist surgery. The patients had arthralgia, degenerative and traumatic arthropathies as well as limited range of motion, but no radiologically detected fractures. All examinations were interpreted by two experienced musculoskeletal radiologists. The findings were compared with arthroscopic findings carried out within 28 days of the CT study. Results: In non-operated and operated wrists the comparison between arthro-MDCT and arthroscopy showed sensitivity, specificity and accuracy ranging between 92% and 94% for triangular fibrocartilage complex (TFCC), between 80% and 100% for intrinsic ligaments located within the proximal carpal compartment, and between 94% and 100% for articular cartilage. Inter-observer agreement between two radiologists, in the evaluation of all types of lesions, was almost perfect (k = 0.96) and statistically significant (p < 0.05). Conclusions: Arthro-MDCT of the wrist provides an accurate diagnosis to identify chondral, fibrocartilaginous and intra-articular ligament lesions in patients who cannot be evaluated by MRI, and in post-surgical patients.

    Bucket handle lesions are vertical longitudinal tears in the meniscus that may displace centrally into the respective medial or lateral compartment, frequently causing mechanical symptoms, including pain, perceived instability, and mechanical locking. Bucket handle meniscal tears are most commonly from a traumatic etiology and are frequently found with concomitant anterior cruciate ligament (ACL) injuries. Multiple imaging signs and associations have been described for the diagnosis of bucket handle meniscus tears, including coronal truncation, absent bow tie sign, double posterior cruciate ligament (PCL), double ACL, displacement of the bucket handle fragment, and disproportionate posterior horn signs. Among meniscal pathology encountered on magnetic resonance imaging or during arthroscopy, bucket handle meniscal tears are infrequent occurrences. Furthermore, the occurrence of displaced medial and lateral bucket handle tears found on imaging and during arthroscopy is very uncommon and is only sparsely reported in the literature. When displaced medial and lateral bucket handle meniscal segments are visualized within the intercondylar notch along with the ACL and PCL, the radiologic findings are referred to as the "quadruple cruciate" sign or the "Jack and Jill lesion." Of the few case reports described in the literature, only one noted displaced medial and lateral bucket handle meniscus tears with an intact ACL and PCL. The current case report outlines a similar rare case of the quadruple cruciate sign: displaced medial and lateral bucket handle meniscal tears located within the intercondylar notch and an intact ACL and PCL.

    Full Text Available This prospective randomised clinical trial evaluated the effect of warmed irrigation fluid on body temperature in anaesthetised dogs undergoing arthroscopic elbow surgery. Nineteen dogs undergoing elbow arthroscopy were included in the study and were randomly allocated to one of two groups. Group RT received irrigation fluid at room temperature (RT while dogs in group W received warmed (W irrigation fluid (36oC. A standardised patient management and anaesthetic protocol was used and body temperature was measured at four time points; (T1 pre-anaesthetic examination, (T2 arrival into theatre, (T3 end of surgery and (T4 arrival into recovery. There was no significant difference in body temperature at any time point between the groups. The mean overall decrease in body temperature between pre-anaesthetic examination (T1 and return to the recovery suite (T4 was significant in both groups, with a fall of 1.06±0.58oC (p<0.001 in group RT and 1.53±0.76oC (p<0.001 group W. There was no significant difference between the groups. At the end of surgery (T3 4/19 (21.1% of dogs were hypothermic (<37oC. The addition of warmed irrigation fluids to a temperature management protocol in dogs undergoing elbow arthroscopy during general anaesthesia did not lead to decreased temperature losses.

  7. Texture analysis of articular cartilage traumatic changes in the knee calculated from morphological 3.0 T MR imaging

    International Nuclear Information System (INIS)

    Objectives: In the present work, we aim to identify changes in the cartilage texture of the injured knee in young, physically active, patients by computer analysis of MRI images based on 3.0 T morphological sequences. Methods: Fifty-three young patients with training injury or trauma in one knee underwent MRI and arthroscopy. Textural features were computed from the MRI images of the knee-cartilages and two classes were formed of 28 normal and 16 with pathology only in the medial femoral condyle (MFC) cartilage. Results: Textural features with statistically significant differences between the two classes were found only at the MFC and the medial tibial condyle (MTC) areas. Three features-combinations, at the MFC or the MTC, maximized the between classes separation, thus, rendering alterations in cartilage texture due to injury more evident. The MFC cartilage in the pathology class was found more inhomogeneous in the distribution of gray-levels and of lower texture anisotropy and the opposed MTC cartilage, though normal on MRI and arthroscopy, was found to have lower texture anisotropy than cartilage in the normal class. Conclusion: Texture analysis may be used as an adjunct to morphological MR imaging for improving the detection of subtle cartilage changes and contributes to early therapeutic approach

  8. Labral-Ligamentous Complex of the Shoulder. Evaluation with double oblique axial MR arthrography. Technical Note

    International Nuclear Information System (INIS)

    Purpose: To assess the ability of double oblique axial (DOA) MR arthrography in evaluating labral-ligamentous complex compared with conventional axial (CA) MR arthrography. Material and Methods: MR arthrography of 51 shoulders, subsequently examined with arthroscopy, were retrospectively reviewed. DOA imaging was performed in all 51 shoulders and both DOA and CA imaging in 37 using a 1.5 T unit with gradient recalled-echo T2*-weighted sequences. DOA imaging was performed using perpendicular planes to the long axis of the glenoid fossa obtained by an oblique sagittal scout image. We compared the ability of DOA with that of CA MR arthrography to assess labral injuries and to demonstrate the whole length of the anterior band of the inferior glenohumeral ligament (AIGHL), which were shown to be intact by arthroscopy. Results: For anterior labral injuries, sensitivity and specificity were 87% and 93% with CA, and 94% and 100% with DOA imaging, respectively. For posterior labral injuries, sensitivity and specificity were 47% and 100% with CA, and 79% and 96% with DOA imaging, respectively. There were no statistically significant differences between CA and DOA images, except for the ability to diagnose posterior labral injuries, where DOA imaging had a significant superior sensitivity (p = 0.0327). DOA images also demonstrated the whole length of the intact AIGHL in 10 of 11 shoulders, while CA imaging showed this in only 3 of 11. Conclusion: DOA imaging was equal or better than CA imaging for evaluating the labral-ligamentous complex

    Diagnosis of intra-articular lesions in children based on clinical examination and MRI is particularly challenging. To evaluate the diagnostic performance of MRI and pre-surgical evaluation of the knee in pediatric patients relative to arthroscopic evaluation as the gold standard. We report diagnoses frequently missed or inaccurately diagnosed pre-operatively. We conducted a retrospective review of MRI and pre-surgical evaluation in children and adolescents ages 1-17 years who were treated by knee arthroscopy during a 21/2-year period. All MRIs were reviewed by a pediatric radiologist blinded to clinical findings. Pediatric orthopedic clinic notes were reviewed for pre-surgical evaluation (based on physical exam, radiograph, MR images and radiologist's MRI report). Arthroscopic findings were used as the gold standard. We calculated the percentages of diagnoses at arthroscopy missed on both MRI and pre-surgical evaluation. Diagnostic accuracy between children and adolescents and in patients with one pathological lesion vs. those with >1 lesion was analyzed. We performed a second review of MR images of the missed or over-called MRI diagnoses with knowledge of arthroscopic findings. We included 178 children and adolescents. The most common diagnoses missed on MRI or pre-surgical evaluation but found at arthroscopy were: discoid meniscus (8/30, or 26.7% of cases); lateral meniscal tears (15/80, or 18.8% of cases); intra-articular loose bodies (5/36, or 13.9% of cases), and osteochondral injuries (9/73, or 12.3% of cases). Overall diagnostic accuracy of MRI and pre-surgical evaluation was 92.7% and 95.3%, respectively. No significant difference in diagnostic accuracy between children and adolescents was observed. When multiple intra-articular lesions were present, lateral meniscal tears were more likely to be inaccurately diagnosed (missed or over-called) on both MRI (P = 0.009) and pre-surgical evaluation (P < 0.001).

    Patients with haemarthros of the knee were examined by MRI and arthroscopy to identify the bleeding source and to determine surgical or conservative therapy. A prospective study was performed on 120 patients who underwent MRI and arthroscopy, point lesions and bleeding sources were documented separately on a standardised form. Arthroscopy demonstrated a ruptured anterior cruciate ligament in 86%, meniscal tears in 55%, disruption of collateral ligaments in 17%, osteochondral lesions in 5% and tears of capsule or plicae in 13%. Disruption of cruciate ligaments caused haemorrhage in all but three cases. In contrast, only meniscal tears located very adjacent to the meniscal basement had bled. Those types of osteochondral lesions caused haemorrhage characterised on MRI by destruction of the subchondral plate and overlying cartilage. Severe lesions of the knee were diagnosed by MRI in 71% to 100%, slight lesions in 13% to 40% of the cases. Single, combined and bland lesions were accurately diagnosed in MRI which permitted a correct prediction of surgical and conservative therapy in 96% and 80%. Morphological criteria in MRI permit identification of bleeding sources in haemarthros of the knee. Different lesion patterns can be separated for the planning of therapy. (orig.)

    Assess the diagnostic accuracy of 3-T indirect magnetic resonance arthrography (iMRA) for hip cartilage and labral pathology detection using arthroscopy as the reference standard and compare it to the published performance of direct magnetic resonance arthrography (dMRA). Between 2009 and 2011, 290 patients suspected of having femoroacetabular impingement underwent iMRA. Our study group consisted of 41 of these patients (17 males, mean age 35 years; 24 females, mean age 33 years) who did not have a prior history of hip surgery and who subsequently underwent arthroscopy. Two experienced musculoskeletal radiologists separately evaluated the randomized and anonymized studies for the presence and quadrant location of labral and cartilage pathology. These recorded data were compared to arthroscopic reports. Forty-one patients had labral pathology, 34 patients had acetabular and 5 patients had femoral cartilage pathology at arthroscopy. Sensitivity, specificity, accuracy, negative- and positive-predictive values for labral lesion detection were respectively 98, 99, 99, 99 and 98 %; for acetabular cartilage lesion detection they were 69, 98, 89, 87 and 95 %; for femoral cartilage lesion detection they were 69, 95, 93 and 39 %. Sensitivities of iMRA by quadrant (anteroinferior, anterosuperior, posteroinferior, posterosuperior) for the labrum were 100.0, 95.0, NA and 85.7 %, for acetabular cartilage were NA, 58.8, NA and 39.5 % and for femoral cartilage were 50.0, 33.3, 75.0 and 75.0 %. NA indicates results not available because of the absence of findings in those quadrants. Specificities of iMRA by quadrant (anteroinferior, anterosuperior, posteroinferior, posterosuperior) for the labrum (95.0, 100.0, 95.1, 67.5 %), acetabular (100.0, 85.7, 92.6, 79.5 %) and femoral cartilage (100.0, 94.7, 96.2, 85.9 %). iMRA at 3 T is accurate in detecting labral pathology suggesting that it is a viable alternative to dMRA.

    Full Text Available Abstract Background Traumatic chondral lesions of the knee are common in football and rugby players. The diagnosis is often confirmed by arthroscopy which can be therapeutic by performing microfracture. Prospective information about the clinical results after microfracture is still limited. Aim To evaluate the short-term outcome of microfractured lesions in professional football ad rugby players in terms of healing and ability to return to play. Methods Twenty-four consecutive professional male players with isolated full-thickness articular cartilage defects on weight-bearing surface of femoral condyles were treated with microfracture. Clinical assessment of healing was done at three, six, 12 and at 18 months by using modified Cincinnati subjective and objective functional scoring. All 24 subjects were periodically scanned by 3-Tesla MRI on the day of the clinical evaluations and scored by the Henderson MRI classification for cartilage healing. A second look arthroscopy was carried out in 10 players five to seven months after surgery to evaluate lesion healing by using ICRS scoring system. This was done due to presence of discrepancy between a "normal" MRI and persistent clinical symptoms. Results This study showed that 83.3% of players' resume full training between five to seven months (mean: 6.2 after microfracture of full-thickness chondral lesions of weight-bearing surface of the knee. Function and MRI knee scores of the 24 subjects gradually improved over 18 months, and showed good correlation in assessing healing after microfracture at six, 12 and 18 months (r2 = 0.993, 0.986 and 0.993, respectively however, the second look arthroscopy score proved to have stronger strength of association with function score than MRI score. Conclusion We confirmed that microfracture is a safe and effective procedure in treating isolated traumatic chondral lesions of the load-bearing areas of the knee. Healing as defined by subjective symptoms and evaluated

  16. Anterior labral tear: diagnostic value of MR arthrography of the shoulder

    International Nuclear Information System (INIS)

    To assess the accuracy of magnetic resonance(MR) arthrography in the diagnosis of anterior labral tear of the shoulder Between september 1996 and February 2000, MR arthrography of the shoulder was performed in 281 patients with a history of shoulder pain or instability. Among this total, only 157 shoulders in 154 patients who underwent arthroscopy or open surgery 0 to 230 (average, 20.9) days after MR arthrography were included in this study; the subjects comprised of 150 males and 4 females with an average age of 23.3 years. MR arthrographs of these 154 patients were analyzed for the presence of anterior labral tears, and the findings were correlated with the arthroscopic and surgical findings. Anterior labral tear was classified as A to D according to its location, as determined by arthroscopy and surgery. (A=4 to 6 o'clock direction, anteroinferior; B=2 to 4 o'clock direction, central; C=12 to 2 o'clock direction, anterosuperior; D= SLAP lesion). The retrospective analysis of MR arthrographs showing false-positive and negative findings was also underthken.. In the diagnosis of anterior labral tear, MR arthrography showed a sensitivity of 94%, a specificity of 90% and an accuracy of 91%. Anterior labral tears were confirmed by arthroscopy or surgery in 62 of the 157 shoulders (39%). Among 62 lesion, two (3%) were observed in area A, 32(52%) in area A+B, nine (15%) in area A+B+C, one(2%) in area A+B+D,13(21%) in area A+B+C+D, two (3%) in area B+C, one(2%) in area B+D, and two(3%) in area C. Among ten false-positive cases, seven were focal lessions (two, three and two lesions in area A, B and C, respectively), and in the remaining three cases, lacated in area A+B, MR arthrography revealed thickening and deformation. All four false negatives were focal lesions (two in area A and two in area C). Other than in focal lesions, in which accuracy was relatively low, MR arthrography showed high sensitivity, specificity and accuracy in the diagnosis of anterior labral tear

    2010-03-01

    All-inside anterior cruciate ligament reconstruction is controversial because the technique is new; as a result, evidence-based clinical outcome studies have yet to be published. The purpose of this article is to consider the following controversies (considered alphabetically): anatomy, biomechanics, biology, bioabsorbables, divergence of the femoral interference screw, expansion or widening of tunnels, fixation, future considerations, graft choice, the learning curve, technique, tensioning, and tibia blow-out fracture. The technique should be learned in stages. In the opinion of the author, the history of sports medicine and arthroscopy has been a progression toward less invasive techniques. In the future, all-inside anterior cruciate ligament reconstruction techniques should become more simple and reproducible, and clinical outcomes must be analyzed with long-term follow-up.

    If a radiologist from 1950 could travel in time to 2011, he or she would be baffled to see how few of the radiological examinations he was familiar with, remain. We review the radiological examinations that have disappeared since X-rays were discovered, and include the causes of their disappearance. Barium studies have mainly been replaced by endoscopy, oral cholecystography by ultrasound, and intravenous urography by CT-scan. Angiography by means of a direct puncture of carotid artery and aorta has been replaced by Seldinger angiography. Pneumencephalography and myelography have been replaced by CT and MRI. Bronchography has been replaced by bronchoscopy and CT-scan, arthrography by MRI and arthroscopy. Many other radiological examinations have been replaced by ultrasound, CT or MRI. PMID:21447222

  20. Diagnosis of shoulder instability in dogs and cats: a retrospective study

    International Nuclear Information System (INIS)

    The glenohumeral joint is a remarkable articulation providing the greatest range of motion of any joint in the body. Glenohumeral stabilityresults from several mechanisms, including those that do not require expenditure of energy by muscle ('''passive mechanisms'') and those that do (''active mechanisms''). Glenohumeral instability has been recognized in 47 shoulders of 45 dogs and one cat. Cases are presented because of chronic foreleg lameness. Shoulder joint pain is obviated by theorthopedic examination. Only 57% of the involved shoulders presented with degenerative joint disease. Signs of instability are recognized under anesthesia using a craniocaudal or mediolateral drawer sign or both. This report describes the radiographic and arthroscopic findings of shoulder instability. Arthroscopy of the shoulder joint allows identification of all intra-articular pathologies. Shoulder instability notfully recognized in the past, appears to be the most common cause of shoulder lameness in the dog

  1. Diagnostic imaging of injuries and overuse in soccer players

    International Nuclear Information System (INIS)

    Soccer is one of the most popular sports worldwide. There is a high incidence of injuries in soccer in which several intrinsic and extrinsic factors play a part. Most injuries are minor, self-limiting and do not need extensive medical treatment or imaging. Imaging can be required for several reasons e.g. when the clinical findings are doubtful, to replace arthroscopy (i. e. of the knee) or for prognostic reasons. All imaging modalities available to the radiologist can be used but MRI is the most valuable imaging modality with its superior contrast resolution and multiplanar capabilities. Basically, injuries in the soccer player can occur anywhere in the body like in every sport. The lower extremities, more specific the knee and ankle, are however the most injured parts. (orig.)

    To determine the prevalence and associated clinical symptoms of pes anserine bursitis in symptomatic adult knees. A retrospective review was performed of the reports of 509 knee MRI studies obtained from July 1998 to June 2004 on 488 patients presenting to an orthopaedic clinic with knee pain suspected to be due to internal derangement. The MRI studies and case histories of all patients reported to have pes anserine bursitis were reviewed. The management of these patients was also noted. The prevalence of pes anserine bursitis as detected on MRI is 2.5%. The commonest clinical presentation was pain along the medial joint line mimicking a medial meniscal tear. We suggest that an accurate diagnosis of pes anserine bursitis on MRI will help prevent unnecessary arthroscopy and possibly initiate early treatment of the condition. Axial imaging is important in these cases to differentiate the bursa from other medial fluid collections. (orig.)

    1994-04-01

    We are interested in the application of computer animation to surgery. Our current project, a navigation and visualization tool for knee arthroscopy, relies on real-time computer graphics and the human interface technologies associated with virtual reality. We believe that this new combination of techniques will lead to improved surgical outcomes and decreased health care costs. To meet these expectations in the medical field, the system must be safe, usable, and cost-effective. In this paper, we outline some of the most important hardware and software specifications in the areas of video input and output, spatial tracking, stereoscopic displays, computer graphics models and libraries, mass storage and network interfaces, and operating systems. Since this is a fairly new combination of technologies and a new application, our justification for our specifications are drawn from the current generation of surgical technology and by analogy to other fields where virtual reality technology has been more extensively applied and studied.

  4. An Unusual Cause of Posterior Elbow Impingement: Detachment of a Hypertrophied Posterior Fat Pad

    Daisuke Hamada

    2015-01-01

    Full Text Available We report a case of a 47-year-old woman who developed posterior impingement of the elbow due to detachment of a hypertrophied posterior fat pad. She reported acute left elbow pain after leaning back onto a hard object with her hand and subsequently experienced a “catching” sensation. Comparison with the magnetic resonance images of a normal elbow revealed a hypertrophied posterior fat pad interposed between the olecranon and olecranon fossa in both elbows, with the fat pad in the left elbow located more inferiorly than that in the right elbow. Elbow arthroscopy showed the olecranon fossa covered by the fat pad, a portion of which was detached from the rest of the pad. Debridement of the detached portion was performed until no impingement was evident. Postoperatively, full extension of the elbow did not elicit pain. Clinicians should include this pathology among the differential diagnoses for posterior elbow pain.

  5. Marginal fractures of the medial tibial plateau: possible association with medial meniscal root tear

    International Nuclear Information System (INIS)

    We report two cases of marginal fractures of the medial tibial plateau associated with medial meniscal root tears. Both patients sustained knee dislocations, with complete tears of the posterior horn medial meniscal root. One sustained a ''reverse Segond fracture''; the other sustained an ''anteromedial impingement fracture'' of the tibial plateau. The meniscal root tears were arthroscopically confirmed and repaired. In the first patient, the integrity of the meniscal root repair was confirmed at a 6-month follow-up arthroscopy for lysis of adhesions. In the second patient, follow-up MRI at 10 months demonstrated a healed meniscal root. The association of medial meniscal root tear with marginal fractures of the medial tibial plateau has not been previously reported. (orig.)

    We report two cases of marginal fractures of the medial tibial plateau associated with medial meniscal root tears. Both patients sustained knee dislocations, with complete tears of the posterior horn medial meniscal root. One sustained a ''reverse Segond fracture''; the other sustained an ''anteromedial impingement fracture'' of the tibial plateau. The meniscal root tears were arthroscopically confirmed and repaired. In the first patient, the integrity of the meniscal root repair was confirmed at a 6-month follow-up arthroscopy for lysis of adhesions. In the second patient, follow-up MRI at 10 months demonstrated a healed meniscal root. The association of medial meniscal root tear with marginal fractures of the medial tibial plateau has not been previously reported. (orig.)

  7. Tendon of the long head of the biceps originating from the rotator cuff - An uncommon anatomical variation: case report

    Full Text Available ABSTRACT Anatomical variations at the origin of the biceps tendon have been described by several authors, but occurrences of an origin in the supraspinatus are rare. It is unclear whether this variation might contribute toward pathological conditions of the shoulder. Our objective here was to describe a case of an anatomical variation in the origin of the tendon of the long head of the biceps. The clinical information, preoperative images and arthroscopic images relating to a patient with an aberrant origin of the long head of the biceps, which was observed during shoulder arthroscopy, were reviewed. In this case study, the origin of the biceps was found in the rotator cuff, without any origin from the supraglenoid tubercle or upper labrum. This variant did not seem to contribute toward the pathological condition of the shoulder, and standard treatment for the concomitant condition was sufficient for treating it.

  8. Evaluation using MRI T2 mapping of the articular cartilage after anterior cruciate ligament injury in young athletes

    International Nuclear Information System (INIS)

    Articular cartilage damage coexisting in the anterior cruciate ligament (ACL) injury in young athletes is not rare. We evaluated the conditions of the articular cartilage using MRI T2 mapping method and compared the vesults with the findings of arthroscopy. From June to August in 2010, we performed ACL reconstruction in 31 patients. We selected 17 cases (eleven men and six women, mean age 19.1 years old), all of whom were athletes and the under 29 years old. Articular cartilage damage was observed in six out of 10 cases, and their T2 values were high on MRI T2 mapping. On the other hand, damage was observed only in one out of seven cases, and T2 values were in the normal level of the mapping. Using MRI T2 mapping, we can evaluate the articular cartilage at an early phase noninvasively. MRI T2 mapping is useful and effective for athletes. (author)

    To evaluate the severity of airway pathologies, quantitative dimensioning of airways is of utmost importance. Endoscopic vision gives a projective image and thus no true scaling information can be directly deduced from it. In this article, an approach based on an interferometric setup, a low-coherence laser source and a standard rigid endoscope is presented, and applied to hollow samples measurements. More generally, the use of the low-coherence interferometric setup detailed here could be extended to any other endoscopy-related field of interest, e.g., gastroscopy, arthroscopy and other medical or industrial applications where tri-dimensional topology is required. The setup design with a multiple fibers illumination system is presented. Demonstration of the method ability to operate on biological samples is assessed through measurements on ex vivo pig bronchi.

    Dynamic and static gadolinium-diethylenetriaminepentaacetic acid(Gd-DTPA)-enhanced magnetic resonance imaging (MRI) were evaluated as measures of joint inflammation in arthritis, by a comparison with macroscopic and microscopic signs of synovitis. Furthermore, the importance of the size of the...... evaluated synovial areas was investigated, as was the optimal time for enhancement measurements. Seventeen rheumatoid arthritis knees and 25 osteoarthritis knees, scheduled for arthroscopy or arthrotomy, were included. Macroscopic and microscopic synovial inflammation as well as nine histologic tissue...... four biopsy sites, and compared to synovial pathology. The rate of early enhancement of the total synovial membrane of the preselected slice, determined by dynamic MRI, was highly correlated with microscopic evidence of active inflammation (Spearman p = 0.73; p < 10(-7). Dynamic MRI could distinguish...

    Advances in orthopedic and arthroscopic surgical procedures of the knee such as, knee replacement, ligamentous reconstruction as well as articular cartilage and meniscus repair techniques have resulted in a significant increase in the number of patients undergoing knee arthroscopy or open surgery. As a consequence postoperative MR imaging examinations increase. Comprehensive knowledge of the normal postoperative MR imaging appearances and abnormal findings in the knee associated with failure or complications of common orthopedic and arthroscopic surgical procedures currently undertaken is crucial. This article reviews the various normal and pathological postoperative MR imaging findings following anterior and posterior cruciate ligament, medial collateral ligament and posterolateral corner reconstruction, meniscus and articular cartilage surgery as well as total knee arthroplasty with emphasis on those surgical procedures which general radiologists will likely be faced in their daily clinical routine.

  13. MR for assessing anterior cruciate ligament reconstructions by tendon grafts

    International Nuclear Information System (INIS)

    150 patients were examined via magnetic resonance (MR) after anterior cruciate (ACL) ligament reconstruction (76 patellar tendon grafts, 53 semitendinosous tendon grafts and 21 sutures). The results of MR were compared with clinical tests (Lachman, pivot-shift and anterior drawer test), in 2 cases with the operative findings, and in one case with arthroscopy findings. In 91% of patients with a clinically stable knee we found a continuous low-intensity ligamental structure. 10 patients were examined twice or more between 8 days and 6 months after surgery. Ligamental structures of low signal intensity did not significantly change their MR characteristics. MR is a valuable noninvasive method for evaluating ligament reconstructions. (orig./GDG)

    This study is for the evaluation of low tesla(0.064T). MR imaging diagnostic accuracy in the internal derangement of the knee. We retrospectively analysed the MR images of 36 injured knees of 35 patients. The presence of tear was determined by arthroscopy or surgery in all cases. The specificity, accuracy, positive predictive value, negative predictive value of of low tesla MRI for the diagnosis of anterior cruciate ligament injury were 83%, 88%, 86%, 77%, 91%, for the posterior cruciate ligament 75%, 95%, 86%, 92%, 83%, for the medial collateral ligament 83%, 96%, 92%, 91%, 92%, for the lateral collateral ligament 67%, 97%, 94%, 67%, 97%, for the menisci 75%, 93%, 89%, 75%, 93%. The low tesla MRI is an accurate method in detection and evaluation of the internal derangement of the knee.

  15. MR imaging of cruciate ligament injury of the knee

    International Nuclear Information System (INIS)

    Diagnostic accuracy of MRI in cruciate ligament injury of the knee was evaluated on 41 knees which were confirmed by means of arthroscopy or arthrotomy. Normal and abnormal conditions of both anterior and posterior cruciate ligaments were correctly identified in 40 of 41 knees (98%). Diagnostic criteria of ligament injury on MRI were as follows: (1) interruption or discontinuity with a partially retained normal morphology of the ligament, (2) expansion or retraction of the width of the ligament, and (3) complete loss of the normal morphology of the ligament. T1-weighted sagittal images alone were satisfactory for diagnosis and additional proton and T2-weighted images were considered to be unnecessary in most cases. MR imaging is a reliable method for the detection of the cruciate ligament injury of the knee. (author)

    Giant cell tumor of the tendon sheath (GCTTS) predominantly occurs in the tendon sheaths of the hand, but rarely in those of the knee. The current study reports the case of a 36-year-old male patient presenting with anterior knee pain. The patient was ultimately diagnosed with GCTTS in the knee mimicking patellar tendinopathy. To the best of our knowledge, this is the first case of its kind. Magnetic resonance imaging revealed a well-defined oval intra-articular lesion located at the proximal segment of the infrapatellar fat pad. The lesion was completely excised under arthroscopy and pathological examination confirmed the diagnosis of GCTTS. There was no evidence of recurrence at the 2-year follow-up examination. The findings of the present study suggest that, despite its rarity, GCTTS should be considered in the differential diagnosis of patellar tendinopathy. PMID:27123148

    A 17-year-old girl with bilateral ball-and-socket ankles reported left medial heel pain. Her left heel had gone into a varus position on tiptoeing, and a painful clunk had occurred when returning to normal standing. The clunk persisted after physiotherapy and treatment with an orthosis. Subtalar arthroscopy and peroneal tendoscopy showed mild diffuse synovitis of the ankle joint, especially over the posterior capsule, and a patch of inflamed and fibrotic synovium at the posterolateral corner of the subtalar joint. The clunk subsided immediately after arthroscopic synovectomy and had not recurred during 5 years of follow-up. We found no other reported cases of ankle and subtalar synovitis occurring in patients with a ball-and-socket ankle joint. PMID:25179452

    Full Text Available 【Abstract】 A case of swelling and anterior painful knee due to tear of mediopatellar plica is reported. The patient also felt clunk of the patellofemoral joint and knee locking. Under arthroscopic examination, a thick and fibrous plica was found medial to patellar, and a bucket tear along the plica from medial patellar retinaculum to infrapatellar fat pad. Polarized microscopic examination showed collagen fiber fragment and loss of light reflecting property. Neuroimmunohistology suggested up-regulation of synovial plica innervation in the area around the crack. This may be related to the pain. The bucket tear of mediopatellar plicacaused pain and lock of knee are more common than previously reported. Key words: Knee injuries; Arthroscopy; Patellofemoral joint

    The infrapatellar fat pad of Hoffa is commonly injured but rarely discussed in the radiological literature. Abnormalities within it most commonly are the consequences of trauma and degeneration, but inflammatory and neoplastic diseases of the synovium can be confined to the fat pad. The commonest traumatic lesions follow arthroscopy, but intrinsic signal abnormalities can also be due to posterior and superior impingements syndromes and following patellar dislocation. Infrapatellar plica syndrome may also be traumatic in aetiology. The precise aetiology of ganglion cysts is not understood; the principal differential diagnosis is a meniscal or cruciate cyst. Hoffa's fat pad contains residual synovial tissue, meaning that primary neoplastic conditions of synovium may originate and be confined to the fat pad. Inflammatory changes along the posterior border of the pad may also be used to help differentiate effusion from acute synovitis on unenhanced MR examinations. (orig.)

    This prospective clinical study evaluates the effectiveness of an alcohol-based hand rub (Avagard™) for pre-surgical hand antisepsis in an equine hospital and compares it with traditional scrubbing technique using 4% chlorhexidine gluconate sponges and water. Prior to elective surgery, 3 board-certified surgeons were randomly assigned to hand antisepsis with either technique. Culture samples of each hand were taken at 4 times: before and after neutral soap hand wash, after scrub or rubbing technique, and after surgery. There was no significant difference in mean bacterial colony forming units between scrub and rub techniques over the 3 time periods (P = 0.6), controlling for initial counts. One horse from the scrub group had a skin incision infection following stifle arthroscopy; this was resolved with medical treatment. The alcohol-based hand rub is equivalent in efficacy for pre-surgical hand antisepsis to traditional water-based scrubs in an equine hospital setting. PMID:26834268

    The main complications of open tibiotalocalcaneal arthrodesis are wound healing disorders and nonunion. Our hypothesis was that arthroscopy and interlocking intramedullary nailing decrease these complications. We retrospectively reviewed six patients (mean age: 58 years; mean preoperative Kitaoka score: 51/100) having undergone arthroscopic tibiotalocalcaneal arthrodesis with retrograde intramedullary nailing between January and November 2011 for equinus deformity of the hindfoot and subtalar instability of neurological origin. Postoperative pain disappeared completely in four cases, one patient presented some pain associated with projection of the proximal locking screw head under the skin and the remaining patient presented fibular tendinitis that resolved after infiltration of anti-inflammatory drugs. The mean postoperative Kitaoka score was 64/100. None of the patients presented any wound healing complications or nonunion. The observed incidence of wound complications and bone consolidation disorders after tibiotalocalcaneal arthrodesis was lower than the ones reported for open tibiotalocalcaneal arthrodesis. Level of clinical evidence IV: retrospective case series. PMID:26984662

    2016-01-01

    There is growing subgroup of patients with poor outcomes after hip arthroscopy for intra-articular pathology suggesting unrecognized cause(s) of impingement may exist. Extra-articular hip impingement (EHI) is an emerging group of conditions that have been associated with intra-articular causes of impingement and may be an unrecognized source of pain. EHI is caused by abnormal contact between the extra-articular regions of the proximal femur and pelvis. This review discusses the most common forms for EHI including: central iliopsoas impingement, subspine impingement, ischiofemoral impingement, and greater trochanteric-pelvic impingement. The clinical presentation of each pathology will be discussed since EHI conditions share similar clinical features as the intra-articular pathology but also contain some unique characteristics.

  3. Comparative study between the Spin-echo and 3-D fast imaging techniques in the Knee evaluation with magnetic resonance

    International Nuclear Information System (INIS)

    We have carried out a retrospective analysis of the results of magnetic resonance (MR) studies in 20 patients, comparing two different sequences. We compared a 2-D spin-echo (SE2D) sequence with a 3-D fast imaging with steady-state precession (FISP3D) sequence in the attempt to compare the reliability of each in the detection of knee injuries. Arthroscopy was employed as a control technique. Our study revealed no statistically significant difference between the two sequences, although the overall sensitivity for the detection of meniscal lesions was slightly greater with the FISP3D sequence; however, the reliability in the detection of ruptures of the posterior cruciate ligament is less with this sequence than with the SE2D sequence. Both sequences showed very low sensitivity in the detection of hyaline cartilage injuries. (Author) 14 refs

    The optimal treatment for combined osteochondritis dissecans (OCD) with considerable bony defect of the lateral femoral condyle (LFC) and torn discoid lateral meniscus is unclear. We present a case of a 15-year-old female who was a gymnast and had a large OCD lesion in the LFC combined with deficiency of the lateral meniscus. The patient underwent the "one-step" technique of osteoperiosteal autologous iliac crest graft and lateral meniscus allograft transplantation after a failure of meniscectomy with repair at another hospital. Twenty-four months postoperatively, clinical results were significantly improved. Follow-up imaging tests and second-look arthroscopy showed well incorporated structured bone graft and fibrous cartilage regeneration as well as stabilized lateral meniscus allograft. She could return to her sport without any pain or swelling. This "one-step" surgical technique is worth considering as a joint salvage procedure for massive OCD lesions with torn discoid lateral meniscus. PMID:27274475

    Full Text Available Groin pain in a performing athlete can be very challenging to diagnose and treat. The differential diagnosis includes intra-articular causes, extra-articular causes and non-musculoskeletal causes. A detailed clinical and radiological assessment of groin pain in this group is critical and can identify the underlying pathology. Diagnostic hip block is a valuable tool to differentiate intra-articular causes from extra-articular causes. Hip arthroscopy can help in identifying some of the elusive intra-articular conditions, which were once undiagnosed and therefore, left untreated, resulting in premature ending of competitive careers. This article attempts to explore current thinking on evaluation of groin pain, particularly in young individuals, and to establish a simple protocol for a clinical and diagnostic approach to this difficult problem.

    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.

    Full Text Available We report a case of partial intrasubstance tear of popliteus tendon as an unusual cause of pseudolocking of the knee. A 13-year-old semiprofessional soccer player applied to our clinic with a locked right knee in spite of the therapy applied (cold pack, NSAID, and immobilization in another institution 20 days after the injury. Significant extension loss was observed in his right knee with 30∘–90∘ ROM. Magnetic resonance imaging (MRI and arthroscopy confirmed the intrasubstance tear of popliteus tendon and synovitis. The ruptured part of the tendon was debrided, and the inflammatory tissue around the tendon, which may lead to pseudolocking, was gently removed with a shaver in order to regain the normal ROM. The patient was discharged with full ROM and weight bearing first day after the surgery. To our knowledge, this is the first case demonstrating intrasubstance tear of popliteus tendon causing pseudolocking of the knee.

    Eighty-nine MR examinations of the wrist were retrospectively analyzed. MRI results were compared with clinical findings and/or arthroscopy. Thin proton density and T2 weighted sequences and 3D DESS weighted sequences were applied on a 1.5 T scanner. On the palmar side three radiocarpal ligaments are recognized including the radioscaphocapitate, radiolunotriquetral, radioscapholunate, and midcarpal triquetroscaphoidal ligaments. Ulnocarpal ligaments include the ulnolunate ligament and the ulnotriquetral ligament. On the dorsal side three ligaments are recognized: the dorsal radiolunotriquetral, and the midcarpal triquetroscaphoidal and triquetro-trapezoido-trapezial. The collateral ligaments include the radial and ulnar collateral ligament. MR is a valuable technique in the assessment of the extrinsic and midcarpal ligaments. Depiction of the extrinsic ligaments can best be accomplished with coronal 3D DESS sequences and sagittal and transverse proton density and T2 weighted sequences with thin slices.

    2014-01-01

    Ulna impaction syndrome ( UIS ) is a degenerative process caused by excessive stress bearing across the ulnar aspect of the wrist, with a series of pathological and clinical changes. Recent studies demonstrate that the biomechanical changes caused by ulnar variance play a crucial role in the process. Currently, the diagnosis of UIS is made by clinical manifestations, physical examinations and imaging examinations, such as the X-ray, Computed Tomography ( CT ), Magnetic Resonance Imaging ( MRI ) and so on. Besides, some special examinations are recommended if necessary, including arthrography, ultrasound and arthroscopy. Depending on the special conditions of patients, either conservative treatment or surgery is effective. The traditional procedures include ulnar shortening osteotomy and Wafer procedure. With the advancement of modern technologies and instruments, some new procedures are created based on them, which lead to the improvement of surgical results.

    A search of the available literature was performed and the role of MR imaging of the knee is discussed. Based on this search the authors concluded that MR has a high sensitivity in detecting any abnormalities in the knee but it does not have the same diagnostic accuracy as a clinical investigation performed by a trained knee specialist when all knee injuries are taken together. It does lead to a decrease in the number of surgical interventions due to its high negative predictive value. For the detection of meniscal injury, MR has the same accuracy as arthroscopy and should be performed in order to avoid unnecessary surgical interventions. A negative MR also obviates further investigation in suspected cartilage damage. This is not true for anterior and posterior cruciate ligament problems where MRI is less accurate than clinical investigation.

  12. Delayed appearance of hypaesthesia and paralysis after femoral nerve block

    2012-03-01

    Full Text Available We report on a female patient who underwent an arthroscopy of the right knee and was given a continuous femoral nerve block catheter. The postoperative course was initially unremarkable, but when postoperative mobilisation was commenced, 18 hours after removal of the catheter, the patient noticed paralysis and hypaesthesia. Examination confirmed the diagnosis of femoral nerve dysfunction. Colour duplex sonography of the femoral artery and computed tomography of the lumbar spine and pelvis yielded no pathological findings. Overnight the neurological deficits decreased without therapy and were finally no longer detectable. We speculate that during the administration of the local anaesthetic a depot formed, localised in the medial femoral intermuscular septa, which was leaked after first mobilisation. To our knowledge no similar case has been published up to now. We conclude that patients who are treated with a nerve block should be informed and physician should be aware that delayed neurological deficits are possible.

    2012-01-01

    An injury to the ligament linking the scaphoid with the lunate is the most common and and budrened with the most negative sequelae cause of the carpal instability. It occurs most frequently as an associated injury at fractures of the distal radius. A review of methods of treatment of the pathology is provided, according to clinical advancement, duration form original trauma and condition of articular structures. Technical complexity of methods is directly related to severity of intrarticular changes. In early, dynamic instabilities, a simple, temporary scapholunate arthrodesis with K-wires is is an useful procedure, preventing further development of chronic instsbility. In later stages. The treatment is technically more demanding, considering re-alignment of carpal anatomy with ligaments or tendons (capsulodesis or tenodesis). An usefulness of arthroscopy in diagnostics and management at any stage of this pathology was emphasized. PMID:23306292

    Lee, Sanglim; Yu, Jae-Ha; Jeon, Suk Ha

    2016-06-01

    Carpal malalignments in malunion of distal radius fracture are considered as an adaptive response of the carpus to loss of normal architecture of the distal radius. This condition leads to mechanical overload, ligament attenuation and progressive dynamic instability around the wrist joint. Radial corrective osteotomy is suggested as a treatment option of carpal malalignment after distal radius malunion. In radiocarpal malalignment, the lunate is usually observed in flexion in contrast to its extension posture in the more common midcarpal malalignment. We report two cases of fixed lunate flexion deformity after a distal radius fracture, in which reduction and fixation of fresh fracture or corrective osteotomy of malunion were not successful. Arthritic changes were observed in the radiolunate joint on arthroscopy. Thus, fixed flexion deformity of the lunate might be associated with posttraumatic arthritic change in the radiolunate joint.

    The use of arthroscopy in the management of intra-articular fractures of the distal radius has become established over the last ten years, but the operative technique is not yet standardised. We report our experience with this technique and give a stage by stage description of the operative procedure. The arthroscopic part of the procedure consists firstly of an evaluation of the bony, cartilaginous and ligamentous injuries and secondly direct visual control of the reduction. The choice of bone fixation depends on the individual preferences of the surgeon but may be influenced by the configuration of the fracture. A literature review reiterates the advantages of arthroscopic assistance in managing these fractures without revealing any disadvantages. However, mastery of the arthroscopic techniques is vital before the full advantages of this type of management can be realised. PMID:18774328

    In patients for whom function is a priority, anatomic reduction and stable fixation are prerequisites for good outcomes. Several therapeutic options exist, including orthopedic treatment and internal fixation with pins (intra- and extrafocal), external fixation which may or may not bridge the wrist, and different internal fixation techniques with dorsal or palmar plates using or not, locking screws. Arthroscopy may be necessary in case of articular fracture. In the presence of significant metaphyseal bone defects, filling of the comminution with phosphocalcic cements provides better graft stability. The level of evidence is too low to allow recommending one type of fixation for one type of fracture; and different fixation options to achieve stable reduction exist, each with its own specific complications. With the new generations of palmar plate, secondary displacement is becoming a thing of the past. PMID:23518070

  17. MRI of Hoffa's fat pad

    International Nuclear Information System (INIS)

    The infrapatellar fat pad of Hoffa is commonly injured but rarely discussed in the radiological literature. Abnormalities within it most commonly are the consequences of trauma and degeneration, but inflammatory and neoplastic diseases of the synovium can be confined to the fat pad. The commonest traumatic lesions follow arthroscopy, but intrinsic signal abnormalities can also be due to posterior and superior impingements syndromes and following patellar dislocation. Infrapatellar plica syndrome may also be traumatic in aetiology. The precise aetiology of ganglion cysts is not understood; the principal differential diagnosis is a meniscal or cruciate cyst. Hoffa's fat pad contains residual synovial tissue, meaning that primary neoplastic conditions of synovium may originate and be confined to the fat pad. Inflammatory changes along the posterior border of the pad may also be used to help differentiate effusion from acute synovitis on unenhanced MR examinations. (orig.)

    In arthroscopic wrist surgery, the resection of dorsal wrist ganglia has become a well accepted practice. As advantages for the minimally invasive procedure the low complication rate and low postoperative morbidity, less postoperative pain and faster recovery over open techniques are discussed. The possibility to assess accompanying joint pathology is considered as another advantage. The importance of identifying a so-called ganglion cyst stalk seems to have been overstated. Regarding the technique, the main discussion points are the size and localisation of the capsular window and the necessity of additional midcarpal arthroscopy. The possibility and results of treatment of recurrent ganglion cysts are still controversial. Our own experience and that of some authors are positive. Hardly mentioned in the literature is the treatment of occult dorsal wrist ganglia and its results, which is considered as very successful by the authors. PMID:25290273

    Full Text Available Avascular necrosis is frequently associated with femoral head involvement and may also be observed in the knee joint, humeral head, wrist and foot. Avascular necrosis may also affect multiple joints. Bilateral involvement of both humeral and femoral heads is a rare condition in the same patient. A patient who complained about a sustained pain in both of his shoulders and hips for a few years applied to our outpatient clinic. The patient who had oral steroid treatment episodically was diagnosed with ulcerative colitis seven years ago. Arthroscopy-assisted decompression to the shoulder joints and core decompression to both hip joints were applied. The range of motions of both humeral and femoral joints was limited and painful prior to the surgical treatment. A follow-up after five years later showed that the patient's range of motions of joints was normal and no further treatment was necessary. [Arch Clin Exp Surg 2013; 2(4.000: 246-250

    Full Text Available We describe the anaesthetic management of arthroscopic repair for complete rotator cuff tear of shoulder in a 59-year-old female with Parkinson′s disease (PD with deep brain stimulator (DBS using a combination of general anaesthesia with interscalene approach to brachial plexus block. The DBS consists of implanted electrodes in the brain connected to the implantable pulse generator (IPG normally placed in the anterior chest wall subcutaneously. It can be programmed externally from a hand-held device placed directly over the battery stimulator unit. In our patient, IPG with its leads was located in close vicinity of the operative site with potential for DBS malfunction. Implications of DBS in a patient with PD for shoulder arthroscopy for anaesthesiologist are discussed along with a brief review of DBS.
