[Articular necroses of the proximal interphalangeal joint. Treatment by resection-distraction using a multicentric MS3 fixator].

PIP joint necrosis occurs in multioperated patients with a history of a dorsal and palmar approach to their joint. Seven cases are reported. The surgical treatment consisted of articular resection followed by external distraction using the MS3 device. Four of the patients regained a painless range of movement (30 to 50 degrees): two of these patients had a clinodactyly of 20 degrees. The final range of movement was better when the extensor apparatus was not injured. Three patients were reoperated: a fusion was performed which healed, more rapidly than normal.
