A histologic analysis of 10 cases of Wilms` tumor in the department of Urology, Chosun University Hospital during 11 years periods from January, l975 to December, l985 has been carried out. A classification based on the tumor differentiation and degree of tubular formation are described. A comparison of the histologic findings with the survival was undertaken and it was found that the histologic classification was significantly correlated with survivals. The results were as follows : I. Low grade tumors(grade I) with predominance of differentiated tubules were associated with a better cure rate than high grade tumors(grade IH) composed mainly of undifferentiated spindle elements : 2 year or more survival rate was lOOf6 for grade I but O% for grade III. 2. Cure rate was lower for the low degree of tubular formation than for the high degree of tubular formation : 2-year cure rates were O%, O%, 33.3%, lOO% for group O, +,++ and +++ respectively. 3. 6 patients with the focal or diffuse anaplasia and sarcomatous stroma had a bad prognosis. giving a survival rate of 0%.

Recurrent dislocation of the peroneal tendon is infrequent but often the injury is a disabling one, and the result of conservative treatment is unsatisfactory. Dislocation of these tendons may be the result of a congenitally shallow groove in the lateral malleolar or of a complete abscence of the groove and the dislocation may be present at birth or may be caused by trauma. We are reporting one case of bilateral recurrent dislocation of the peroneal tendons with- out any history of trauma in which disturbed superior peroneal retinaculum was reconstructed by transposition of the calcsneofibular ligament to the lateral side of the peroneal tendons. The calcaneal insertion of the calcaneofibular ligament was mobilised with a small bone block and reinserted in its bed after the transposition. After a follow up of 13 months, the result was satisfactory.

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.
