We have compared the computed tomographic(C. T.) findings with those of conventional roentgenogram(simple AP and lateral radiograms) in 18 cases of osteochondritis dissecans of the capitellum humeri available for review. Among the 18 cases, 2 cases of them had a lesion of osteochondritis dissecans on C. T. which, however, had not been found on conventional rentgenograms. Fro the 5 cases, which had not clearly found on conventional rentgenograms, 2 loose body on conventional view, 3 cases had different numbers and locations of loose body on C. T. films. On the bases of our findings, we recommend that C. T. is necessary in early detection and the determination of anatomical location and status of osteochondritis dissecans of capitellum.

Osteochondritis dissecans (OCD) of both femoral condyles is very rare, with no previously reported cases of bilateral OCD of both knees in two siblings. We report on a brother and sister with both femoral condyle OCD with a description of surgical technique and clinical results. Fixation using headless compressive screws, osteochondral autologous transplantation and autologous chondrocyte implantation were all successful.

PURPOSE: The purpose of this study is to identify bilateral differences of physeal closure of the lateral compartment of the elbow in osteochondritis dissecans (OCD) and related factors with premature physeal closure. METHODS: Initial radiographs of the bilateral elbows in 40 baseball players with OCD (group I) were reviewed for the status of physeal closure of the lateral compartment; capitellum, radial head, lateral epicondyle. Forty baseball players with medial epicondylar apophysitis (group II) were enrolled as a control. Relative status of physeal closure of dominant elbow was defined as early, same, and delayed. Bilateral differences of the status of physeal closure were analyzed between groups, and according to the radiographic stages, extent of the lesions and demographic factors in group I. RESULTS: Significant early physeal closures of dominant elbows were identified in group I in capitellum (group I, 55%; group II, 3%), radial head (group I, 53%; group II, 3%), and lateral epicondyle (group I 37%; group II, 5%). In group I, advanced stage and extended lesion showed early lateral compartment physeal closure especially in capitellum and radial head, and players with longer career length and limitation of motion showed early closure. CONCLUSION: Over the half of the adolescent baseball players with OCD demonstrated early radiocapitellar physeal closures of dominant elbow in initial presentation. Because premature physeal closure contributes to the development of arthritis without appropriate radiocapitellar remodeling, early detection of OCD is essential for prevention of arthritis and successful conservative management.

Along with the popularity of youth movement, the incidence of osteochondritis dissecans (OCD) showed a trend of increase, but its pathogenesis is not yet clear. Previous studies suggested that trauma is the main potential cause, but with the emergence of vast family cases, hereditary factor is also gradually taken seriously. Arthroscopy is the "gold standard" for diagnosing OCD, but for the patient with early incomplete joint surface lesions, the diagnositic value of MRI is better than the arthroscopy. For the patients with stable form OCD, nonoperative management should be used such as adjusting activity, fixator and drugs; for the patient with unstable form OCD or failing after conservative treatment, surgery should be generally used such as joint clearing, drilling, microfracture method, fixation and transplantation. With the progress of research, stem cell technology and platelet-rich plasma gradually applied in cartilage repair, which will improve the curative effect of OCD, but still further clinical and experimental research, and also a long-term effective follow-up are needed.

Osteochondritis usually occurs in the epiphyseal center of children. Common sites of involvement of osteochondritis are the femoral head, tarsal navicular, talus, lunate, but the patellar involvement is rare. The exact cause of osteochondritis is unknown but it is believed to be traumatic or nontraumatic (idiopathic) in origin. This disease was first described by Kohler in 1908 and characterized by radiographic finding of increased density in the patella We have experienced here one case which is believed to be osteochondritis of the patella.

To evaluate the radiographic characteristics of osteochondritis dissecans (OCD) and useful parameter for predicting mechanical stability, we retrospectively analysed 26 plain radiographic examinations and seven MR imagings in 28 cases of OCD in 24 patients. Typical radiologic findings were osteochondral defect with sclerotic rim of variable thickeness and osteochondral fragment. Sites of osteochondral defect were medial (35.9%) or lateral (32%) femoral chondyle and medial (7.1%) or lateral (25%) side of talar dome. Sclerotic rim was seen in 24 cases (85%) and osteochondral fragments including nine loose bodies were seen in 21 cases (75%). The size of osteochondral defect with unstable fragment (average 2.05cm) and loose body (2.04cm) in the knee joint were similar to, but statistically larger than that with stable fragment (1.35cm). All osteochondral defects were well visualized on MR images. Abnormalities of articular cartilage and effusion in the interface between the parent bone and fragment were seem in five cases of which there were confirmed three unstable cases arthroscopically. We conclude that size of defect may be a good parameter for predicting mechanical stability and MRI may be useful in the diagnosis of OCD and determining the methods of treatment.

The purpose of this study was to investigate clinical and radiological outcomes of multiple drilling in case of failed conservative treatment of juvenile osteochondritis dissecans in athletes. We treated 37 lesions from 30 athletic patients who failed conservative treatment for juvenile osteochondritis dissecans. Multiple drillings were done for 32 lesions and multiple drilling and bioabsorbable pin fixations were done for 5 lesions. Lysholm score, Hughston clinical scale were used for clinical evaluation before and last follow up of treatment. For radiologic evaluation we used magnetic resonance imaging at 3 months and 12 months after operation. Of all 37 lesions, 11 lesions were located on medial femoral condyle, 2 lesions on lateral femoral condyle and 24 lesions on trochlear groove. There were clinical and radiological improvement from Hughston scale after operative treatment. Twenty-five patients among 30 returned to the sports activity. There were no specific complications after operation. Multiple drilling and bio-absorbable pin fixation of juvenile athletic osteochondritis dissecans patients after failure of conservative treatment showed good clinical and radiologic results. So it would be helpful for juvenile athletic patients to return to sports activities.
