[Indications for free groin flap-plasty in severe forearm injury (case report)].

A case with a severe gun shot wound of the palmar ulnar distal forearm and wrist is presented. The initial treatment included reconstruction of the ulnar nerve by means of nerve grafts and soft tissue coverage using a free microvascular groin flap. This represents a procedure which is certainly applied only very exceptionally at our department. Inspite of consequent complete flap necrosis due to arterial thrombosis, sensory recovery was sufficient for protective sensibility. The probable reasons of arterial thrombosis are discussed.
