Effect of Reduction and Fixation of Posterior Malleolus Fracture on The Stability of Ankle Fracture with Dislocation
Abstract
Objective: To compare the effect of internal fixation of posterior malleolar fracture with ankle fracture and investigate the effect of posterior malleolar fracture fixation on ankle stability.
Methods: Operation was performed on 56 patients with ankle fractures involving the posterior malleolar, 36 cases were treated with posterior malleolar fixation (posterior malleolar internal fixation group), and 20 cases were treated without posterior malleolar surgery (posterior malleolar non-fixation group). The results were compared and scored with Olenud-Molander ankle function scoring system.
Results: 56 patients were followed up for 12~36 months. One patient with open wound of each group was infected with superficial soft tissue before surgery, completely healed after anti-infection and transposition. All ankle fractures were healed. 5 cases in posterior malleolar non-fixation group were not recovered eventfully after operation, and the ankle joint was completely restored after subsequent fixation. One year after the operation, Olenud-Molander ankle function scoring system was graded: posterior malleolar fixation group: 24 cases in excellent, 10 cases in good, 2 cases in fair, and the excellent-good rate was 94. 44% (34/36); posterior malleolar non-fixation group: 8 cases in excellent, 10 cases in good, 2 cases in fair, the excellent-good rate was 90.00% (18/20).
Conclusions: Reduction and fixation of posterior malleolar fracture has an effect on stability of ankle joint. Attention should be paid to the management of posterior malleolus fracture
