Background: Traumatic dislocation of the tibialis posterior tendon at the ankle is a rare injury. Some of these cases are misdiagnosed as ankle sprains and are not treated properly. In addition, because the conservative treatment is not as effective as the surgical treatment, it is essential that patients be diagnosed early so that proper surgical treatment can be performed.

Rupture of the tibialis posterior tendon associated with ankle fracture is rare and difficult to diagnose. This rupture can be easily overlooked because the clinical examination is limited owing to acute pain related to a closed ankle fracture. Complete rupture of the tibialis posterior tendon can be identified by a loss of tension during ankle fracture fixation, but partial rupture is more difficult to detect because the tibialis posterior tendon can maintain its tension.

Tibialis posterior tendon rupture in the setting of pronation-type ankle fractures can lead to long-term debility as a result of chronic tendon dysfunction. This rare injury pattern presents a diagnostic challenge because thorough preoperative examination of the function of the tendon is limited by pain, swelling, and inherent instability of the fracture. As such, a high index of suspicion is necessary in ankle fractures with radiographs showing a medial malleolus fracture with an associated suprasyndesmotic fibula fracture. Read More

Management of posterior malleolus fractures continues to be controversial, with respect to both need for fixation and fixation methods. Fixation methods include an open posterior approach to the ankle as well as percutaneous reduction and fixation with or without arthroscopy for visualization of the articular surface. Plain radiographs are unreliable in identifying fracture pattern and intraoperative reduction, making arthroscopy a valuable adjunct to posterior malleolus fracture management. Read More

In this case report, we present an acute rupture in the muscular tendinous junction of a posterior tibialis muscle in a bimalleolar closed ankle fracture after a high-energy trauma in a 30-year-old patient with no significant medical history. Fracture was confirmed by simple X-rays, and was treated with an open reduction in which both of the fractures were treated with osteosynthesis material and reparation of the syndesmosis. If left untreated, this uncommon finding can result in a bad postsurgical outcome; we believe this injury is more common but under-reported in the literature. Read More

Acquired flatfoot deformity in adults is usually due to partial or complete tearing of the posterior tibial tendon, with secondary failure of other structures such as the plantar calcaneonavicular (spring) ligament (SL), which maintain the medial longitudinal arch. In flexible cases, the tibialis posterior can be replaced with the flexor digitorum longus. It is common practice to suture the SL directly in the case of a tear; however, if the tear is complete, suturing directly to the ligament alone will not be possible. Read More

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. Read More

The acute rupture of the tibialis posterior (TP) tendon, compared to an acute rupture of the Achilles tendon, is a quite uncommon disease to be diagnosed in the emergency department setting. In most cases symptoms related to a TP dysfunction, like weakness, pain along the course of the tendon, swelling in the region of the medial malleolus, and the partial or complete loss of the medial arch with a flatfoot deformity precede the complete rupture of the tendon. In this case report, we describe an acute rupture of the TP tendon following a pronation-external rotation injury of the ankle with no association of a medial malleolus fracture and with no history of a prior flatfoot deformity or symptoms.
