手指PIP関節背側脱臼骨折の治療経験

抄録

We experienced 5 cases of fracture-dislocation of PIPJ and all were treated by surgery. Volar plate advancement by Eaton's method was done to 1 fresh case, while all the others were operated by Wilson's method, that is, open reduction and internal fixation by 2 or 3 Kirschner wires. The result was satisfactory, because pain was relieved and good motion of PIPJ was restored. But on radiological examination osteoarthritic changes were seen on every cases from minimal to severe degree. It was mainly because of damage of articular cartilage by trauma itself. But I think it is essential to achieve complete anatomical reduction of fragments by operation.
