Supracondylar fractures of the humerus: a prospective study of percutaneous pinning.

Abstract

In 1981, we designed a protocol to treat displaced supracondylar fractures using a modified technique of closed reduction and percutaneous pinning. After the fracture was internally fixed, intraoperative anteroposterior (AP) radiographs of each distal humerus were compared. The reduction and pinning was accepted only if the radiographs demonstrated that Baumann's angle was < or = 4 degrees of that on the normal side. Seventy-one patients had clinical and radiographic evaluations at an average of 2 years 6 months after the operation. According to Flynn's criteria, the results were satisfactory in 70 patients and unsatisfactory in one. No patient had a cubitus varus deformity at follow-up evaluation.
