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.

A Case of Ehlers-Danlos Syndrome

The patient is a 4 years old boy. His parent noticed the valgus deformities of the feet and the lameness when he was 2 years old. His mother has been also noticed the laxity of the joints and the velvetiness of the skin.At our clinic, we pointed out spinal deformity and lateral mobility of the knee.On examination, hyperelasticity in all over the body, especially in extremity, and hypermobility in all joint were admitted, but no scar tissue following to incurable wound which is characteristic to Ehlers-Danlos syndrome because of fragility of skin.Rentgenographical findings showed thoraco-lumbar kyphoscoliosis and both coxa valga, but no luxation of the hips. Laboratory findings was not abnormal.Histologically, connective tissue around blood vessels was sparse and elstic fibers were reduced or crowded.
