A novel technique to manage paradoxical extension: Case report.

Paradoxical extension was first described, and termed "lumbrical-plus" finger, by Parkes in 1970. It is characterized by extension of the interphalangeal joints when flexing the fingers. The It is most common in the middle finger. Treatment involves lumbrical muscle release or a flexor digitorum profundus graft of appropriate length. A search of the literature found no reports of results of conservative management. The present case report describes a novel conservative technique for lumbrical-plus deformity.
