Autogenous graft repair using semitendinous tendon for a chronic multifocal rupture of the extensor hallucis longus tendon: a case report.

Chronic multifocal closed rupture of the extensor hallucis longus tendon is an extremely rare injury. Previously, chronic multifocal partial rupture of the extensor hallucis longus tendon had not been reported. This case study reports one case of autogenous graft repair of a chronic multifocal rupture of the extensor hallucis longus tendon using a semitendinous tendon autograft.
