Surgical treatment for TF has become the consensus of the majority of clinicians, but how to clearly expose the posterior malleolus is still inconclusive.Īfter years of clinical practice, we found ankle joint dislocation (AJD) treating TF with comminuted posterior malleolus fracture can achieve the goal of clear exposure, exact reduction, and good effect. Patients often had a certain degree of sequelae after treatment, ranging from walking instability, joint deformity, traumatic arthritis, even to joint stiffness. The reduction and fixation of this type fracture is still a big problem in the medical profession. The surgery of TF was difficult with poor effect, especially for the comminuted posterior malleolus fracture. TF is the fracture of medial malleolus, lateral malleolus and anterior or posterior edge of the tibia. TF, also called as cotton fracture, is a serious type of ankle fracture, which was often accompanied by ligament injury of the ankle and dislocation of the ankle joint. Severe situation can accompany with the dislocation and the rupture of inferior tibiofibular syndesmosis. Ankle fracture belongs to the intra-articular fracture, which can be divided into single ankle fracture, bimalleolar fracture, and trimalleolar fracture (TF) according to injury mechanism and severity. The number of patients with ankle fractures was increased year by year, ranking the first in the intra-articular fracture. Ankle fracture is a common clinical fracture, accounting for about 3.9% of the total body fractures. The ankle joint is the weight-bearing joint of the human body, which the stability and flexibility of the ankle joint is very important for the movement of the human body. The ankle joint or the talocrural region is the region where the foot and the leg meet. Ankle joint dislocation can make joint cartilage restore accurately with excellent results. According to the Baird–Jackson ankle scoring system, the excellent and good result was 28 cases, fair was 2 cases which the excellent and good rate was 93.3% without talar necrosis in any cases.Īnkle joint dislocation can achieve the satisfactory results in treating dislocated trimalleolar fractures accompanied with the complex posterior malleolus fracture without separation of the tibiofibular syndesmosis. The average follow-up period was 13 months.

Internal and external malleolus fracture was fixed by the conventional approach. After fully revealed the posterior malleolus and distal articular surface of the tibia, the anatomical reduction of comminuted bones with joint cartilage and posterior malleolus was achieved by fixed with absorbable screw or Kirschner wire. The talus and the distal end of internal and external malleolus were pushed the outside to form the lateral dislocation of the ankle joint. Longitudinal curved incision in medial malleolus was made in ankle joint dislocation and subluxation was automatically formed by appropriate traction of ankle joint. They were all treated by ankle joint dislocation and the surgical results were evaluated by the Baird–Jackson ankle scoring system. Patients who had dislocated trimalleolar fractures accompanied with the complex posterior malleolus fracture without separation of the tibiofibular syndesmosis were retrospectively analyzed and 30 patients were enrolled the study. To explore the therapy of ankle joint dislocation treating dislocated trimalleolar fractures accompanied with the complex posterior malleolus fracture without separation of the tibiofibular syndesmosis and improve surgical results.
