We reported a novel method of primary arthroplasty of the proximal Interphalengeal joint (PIP) by rotatinal osteotomy of the proximal phalengeal head. A 58-year old man sustained an Incompiete amputation of the left index finger with 60% of the dorsal articular surface missing of the proximal phalengeal head on February 23, 2002. On the same day, he underwent arthroplasty that used the Intact volar articular surface in a rotational osteotomy of the neck of proximal phalengeal head with repaired vessel and nerve. There was no complication. Eighteen months later the PIP joint had an active renge of motion of 0 to 60°and a passive range of motion of 0 to 90°with satisfactory result.
The technique is a useful alternative to other forme of arthroplasty, and is able to provide satisfactory functional results when there is a dorsal defect of the head of the proximal phalanx.
