Ankle fractures represent an exciting field of traumatology because of the wide variety of clinical presentations, injury mechanisms, and treatment options. Rupture of the posterior tibialis tendon (PTT) with ankle fracture can occur during trauma that involves pronation and external rotation of the foot or, less commonly, secondary to direct trauma to the ankle. This tendon injury is uncommon and probably misdiagnosed in many cases, because of the difficult clinical examination secondary to the pain and swelling. The identification and early treatment of PTT tears is essential for good functional outcomes to prevent the main mid- to long-term complication of disabling acquired flatfoot due to tendon failure. In the present report, we provide a review of the published data regarding ankle fractures associated with PTT rupture and describe our experience with a case of a multifragment medial malleolus fracture and complete rupture of the PTT diagnosed intraoperatively and surgically treated in a 34-year-old male, with 2.5 years of follow-up.
