Anomalous supratendinous course of the fifth extensor compartment artery: a case report.
Vascularized bone grafts have been successfully used in the treatment of carpal bone nonunion and avascular necrosis. The 4 + 5 extensor compartmental vascularized bone graft based on the fourth extensor compartment artery with retrograde blood flow through the fifth extensor compartment artery is the pedicle of choice for vascularized bone grafting of the lunate. This case report describes an anomalous supratendinous course of the fifth extensor compartment artery. The recognition of this anatomic variant is important for the safe dissection of the fifth extensor compartment artery.
