Recently we have experienced 4 patients of the congenital radioulnar synostosis.3 cases were bilateral radioulnal synostosis and 1 case was unilateral.2 of the bilateral cases were treated by method of resecting their radial head and fixing their forearms in supination with a kirschner wire and a screw.Postoperatively 2 patients have been improved ADL.

Dorsal Dislocations of the Metatarsopharangeal Joints

The dorsal dislocations of the metatarsopharangeal joints are uncommon. Recently we have experienced a case of these dislocations at 2nd, 3rd, 4th metatarsopharangeal joints.These dislocations could not be reduced by manipulation under lumbar anesthesia next day after injury, they were, therefore, necessary to perform open reduction.Judging by the operation findings, we considered that most significant irreducible factor was fibrocartilagenous plate.

A Follow-up study of Chiari's Transverse Pelvic Osteotomy

Recently we have few chance to see the older child with untreated CDH owing to the progress of management for CDH in new-born baby or in infant. However incidence of the secondary O A. that occurs following dislocation or subluxation seems to be relatively increasing.In our clinic we performed the Chiaris transverse pelvic osteotomy for 14 cases of subluxation with acetabular hypoplasia in these 3 years. Now we report the result of the operation with some discussions, though period of follow-up study is short.

Osteochondritis Dissecans of the Elbow Joint in Children Sports

Nine patients with osteochondritis dissecans of the elbow joint were seen at the Beppu National Hospital during past four years. Particular emphasis was given to a discussion of the history of the sports and results.In baseball there were seen most commonly, but two cases were seen in vollyball. Eight cases were treated by operative measure and one conservative measure.According the result, if the fragment remains in situ, then conservative measures are to be adopted particulary in children.
