osteochondritis dissecans capitellum

Physical examination reveals tenderness over the radiocapitellar joint in the posterolateral elbow in some cases. The involvement of the capitellum is more diffuse, with radiographs revealing loss of the normal contour of the capitellum ( ). JEFFREY GUTTMAN, M.D., Resident, Orthopaedic Surgery. Unfortunately, except for a few circumstances, there is no consensus at this point on an acceptable system. For a general discussion of osteochondritis dissecans refer to the parent article - osteochondritis dissecans. Osteochondritis dissecans (OCD) of the capitellum is an overuse injury most commonly seen in young overhead athletes such as throwers and gymnasts. Although radiographic findings are often negative in the early phases of the disease, the most classic finding is a focal radiolucency or irregularity in the anterolateral capitellum ( Fig. Patients who present with OCD of the capitellum are typically athletes between ages 11 and 21 years ( ). Grade I Osteochondritis Dissecans in a Young Professional Athlete. Along the same lines, female gymnasts invoke a similar injury mechanism through repetitive loading of the radiocapitellar joint with their arms in extension ( ). OCD usually causes pain during and after sports. Osteochondritis dissecans lesions of the capitellum in overhead athletes: a review of current evidence and proposed treatment algorithm. Ultrasonography is another potential diagnostic imaging tool for capitellar OCD. With delayed presentation, patients may lack the terminal 15 to 30 degrees of elbow extension ( ). Axillary radiographic view of the elbow. Keywords: elbow, osteochondritis dissecans, baseball INTRODUCTION Osteochondritis dissecans (OCD) of the capitellum is a leading cause of elbow disability in adolescent athletes and generally af-fects those, such as baseball players and gymnasts, who engage in repetitive overhead or weight-bearing activities involving the upper extremities. CRAIG MORGAN, M.D., Attending, Orthopaedic Surgery. Among male relatives of affected males, the prevalence rate is 14.6%. Finally, it also commonly occurs in persons who participate in racquet sports and in weight lifting. CASE HISTORY: This Patient is a 14 year old right hand dominant male … The Research in Osteochondritis of the Knee (ROCK) study group has come to define OCD as “a focal, idiopathic alteration of subchondral bone with risk of instability and disruption of adjacent articular cartilage that may result in premature osteoarthritis” ( ). Use of repeated imaging, although intuitively a good idea, is not established as a viable method to determine the appropriate timing of return to activities. Although radiography is a crucial initial imaging study, its sensitivity for detection of capitellar OCD is as low as 66% according to one study ( ). 32.1 ). Curr Rev Musculoskelet Med. Panner’s disease must be considered in the differential diagnosis of a young athlete with elbow pain. The separated fragments are sometimes called “joint mice”. A localized injury and subsequent separation of articular cartilage and subchondral bone of the capitellum ; Epidemiology ... - Osteochondritis Dissecans of Elbow B 6/7/2020 262 . Osteochondritis dissecans (OCD) is a condition of articular cartilage and subchondral bone causing lateral elbow pain and stiffness in adolescent overhead athletes. In the elbow, an OCD is localized most commonly at the humeral capitellum. An elbow ligamentous stability examination should be performed to assess for both ulnar collateral ligament insufficiency and posterolateral rotatory instability. Grade II lesions are stable when probed but demonstrate partial discontinuity. Like osteochondritis dissecans of the knee, osteochondritis dissecans of the capitellum, or OCD, involves a similar lesion in the elbow of young athletes. USA.gov. A capitellar OCD prevalence study used ultrasound as the screening examination and found that it had a 100% positive predictive value. Osteochondritis dissecans of the capitellum. In the long term OCD can lead to subsequent dege… Osteochondritis dissecans of the capitellum is a well-recognized cause of elbow pain and disability in the adolescent athlete. A disadvantage to consider with CT is the radiation exposure imparted on the young athlete. Stage IV lesions are characterized by separation from the capitellum chondral surface by a high signal interface. Ultimately, repetitive stress of this nature leads to disruption of a localized portion of the subchondral bone and, if allowed to progress, the overlying articular cartilage. MRI has proved useful for better characterizing OCD lesions and guiding treatment. As in the treatment of knee OCD lesions, results of nonoperative treatment are better in younger, prepubescent athletes with wide open physes ( ). Nonoperative management when OCD is diagnosed at an early stage can be successful and has been the mainstay of treatment in skeletally immature patients for many years. 22 Abstract Background: The goals of this study were to … eCollection 2020 Nov. Logli AL, Bernard CD, O'Driscoll SW, Sanchez-Sotelo J, Morrey ME, Krych AJ, Camp CL. A grade IV lesion is either an empty defect, a defect with a dislocated fragment, or a loose fragment lying within the bed. Crepitus at the elbow may be palpable with flexion and extension. Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. On ultrasound, loss of the smooth articular surface served as an excellent indicator of an OCD . The etiology of this disorder is multifactorial and often cannot be determined. There is a lack of consensus on what MRI findings do or do not indicate instability; however, most writers believe that unstable OCD lesions can be identified on T2-weighted imaging from a fluid signal between the OCD and the underlying bone, as well as from a discrete round high–signal intensity area representing a cyst under the OCD lesion ( ) ( Fig. The T1-weighted MR image demonstrates uniform low-intensity changes in the adolescent athlete the synovial fluid.The cartilage is damaged and be...
