Hemi-hamate osteochondral transplantation in proximal interphalangeal dorsal fracture dislocations: a minimum 4 year follow-up in eight patients.

Research output: Contribution to journalArticle

Abstract

Fracture dislocations of the PIP joint are challenging to treat. In hemi-hamate arthroplasty, the palmar lip joint surface is reconstructed using an osteochondral graft from the hamate and the immediate stability permits early movement. In the long term, collapse of non-vascularized osteochondral grafts might lead to degenerative arthritis. We examined the radiographic result after a minimum of 4 years with special reference to the development of osteoarthritis and its relation to clinical symptoms in eight patients, mean age 49 (25-66) years. After a mean of 60 (48-69) months, the arc of motion was 67 degrees (45 degrees -95 degrees ) at the PIP joint and grip strength was 91% of the uninjured side. The visual analogue score for pain (0-100) was 10 (0-70) mm. Severe arthritis (grade IV) was found in two and mild arthritis (grade II) in another two patients, but only one of these four cases had troublesome pain. The hemi-hamate technique is an attractive alternative to other treatment options, but some cases develop osteoarthritis in the medium term.
