Posterior tibialis tendon rupture associated with closed medial malleolus fracture and avulsion of anterior talofibular ligament: A case report and review of the literature

摘要

Traumatic rupture of posterior tibialis tendon in association with medial malleolus fracture is extremely rare. We demonstrate our experience in the management of a complete posterior tibialis tendon (PTT) rupture and anterior talofibular ligament avulsion fracture from the talus in association with medial malleolus fracture in a 30-year-old male motorcyclist without any open wounds. We believe this to be the first reported injury of this type in the literature. Closed ankle fractures may obscure surrounding tendon rupture and the clinician may be tempted to focus on the osseous injuries rather than the significance of associated soft tissue injures. This particular case demonstrates the importance of assessing for PTT injury in situations where high velocity impact to the ankle results in malleolar fracture.
