Conversion of a ring finger metacarpophalangeal joint arthrodesis to arthroplasty: a case report.

摘要

This case report presents the conversion of a ring finger metacarpophalangeal joint arthrodesis to arthroplasty, using a pyrocarbon implant. The patient sought a conversion secondary to poor grip strength and inability to perform basic tasks in his job with the Marine Corps. Three months after surgery he had a stable joint and a 50% increase in grip strength.
