Abstract
We report three cases of interpositional arthroplasty of the metacarpophalangeal (MP) joint of the hand.
Case 1. Fifty two-year-old woman sustained giant cell tumor of the head of the left third metacarpal, and underwent en-bloc resection, iliac bone graft, and interpositional arthroplasty using the fascia of the external oblique muscle. Four years and two months after surgery, she complains minimal pain and the motion of the MP joint is 25°/65°.
Case 2 & 3. Sixty three-year-old man sustained aseptic necrosis of the bilateral metacarpals, and underwent interpositional arthroplasty using the fascia lata. Three years after surgery, he complains no pain and the motion of the MP joints are 25°/50° at the right side and 25°/55° at the left side.
Interpositional arthroplasty using the fascia should be considered as one option of arthroplasty of the MP joint.
