| Popis: | A 49-year-old woman with rheumatoid arthritis who underwent replacement arthroplasty of second to fifth left metacarpophalangeal joints with silastic implant seven years ago presented with a complaint of mild pain and discomfort on the replaced joint of index finger. Ulnar deviation had relapsed, with severe swan neck deformities. Computed tomography examination demonstrated that the tip of the stem of the silicon implant penetrated the second metacarpal. We confirmed that finding surgically, and we performed a revision surgery successfully with autogenous bone grafting from distal radius. As the patient had undergone finger joint replacement surgery with silastic implant, nontraumatic perforation of the bone cortex by the implant could happen in a long-term process. On long-term follow up of silastic arthroplasty of finger joint, the possibility of nontraumatic perforation of the finger bone by the prosthesis should be considered, especially in the coexistence of severe finger deformities such as swan neck deformity. |
