Abstract：Objective To compare the clinical effects and complications of three different internal fixation methods for posterior malleolus fracture.Methods Eighty-five ankle facture-dislocation patients combined with posterior rnalleolus fracture in author's hospital were retrospectively reviewed from March 2010 to January 2015.Of the 85 fractures that fit into Lauge-Hansen categories,8 were classified as supination-external rotation type Ⅲ,45 were supination-external rotation type Ⅳ,5 were pronation-external rotation type Ⅲ,13 were pronation-external rotation type Ⅳ,and 14 were pronation-abduction type Ⅳ.Patients were divided into three groups according to internal fixation methods:29 patients with posterior-anterior screw fixation were group A,31 patients with posterior T-type plating were group B,25 patients with anterior-posterior hollow screw fixation were group C.After the surgeries,complications and reduction qualities in each group were recorded,and clinical outcomes were evaluated at the lastest follw-up by American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale.Results The followed-up were average (27.67 ± 8.36) months,ranged 18-48.The postoperative reductions were as follows:25 in group A,28 in group B,11 in group C.There were 1 patient with deep infection and 5 patients with contracture of flexor hallucis longus muscles in group B,meanwhile 7 patients with malposition of lag screws in group C.AOFAS scores were no significant difference at last follow-up between groups (P＞0.05).The complication rates of group A,B and C were 6.90％,29.03％ and 44.00％,respectively (P＜0.05).Conclusion The posterior-anterior screw fixation on the treatment of posterior malrleolus fracture has better clinical outcomes and less complications than posterior T-type plating or anterior-posterior screw fixation.
