title: Hallux flexion deformity secondary to entrapment of the flexor hallucis longus tendon after fibular fracture.
abstract: This article presents a case of entrapment of the flexor hallucis longus tendon after open reduction and internal fixation of a Weber C ankle fracture resulting in interphalangeal joint contracture of the hallux. Pathology involving other tendons at the foot and ankle associated with ankle fractures is reviewed. Other scenarios of flexor hallucis longus pathology are discussed. Flexor hallucis longus anatomy, as related to distal fibular fractures, is outlined, and a recommendation is made to consider flexor hallucis longus entrapment as a cause of hallux dysfunction after open reduction and internal fixation of an ankle fracture.
