A RESEARCH ON ANATOMY OF LIGAMENTS AROUND THE ANKLE JOINT AND ITS CLINICAL APPLICATION

ObjectiveTo observe periarticular ligaments of the ankle and study the treatment of fracture of ankle complicating its ligament injuries.MethodsFifteen adult ankle(30 sides) samples were dissected and the form of surrounding ligaments observed.The American Orthopaedic Foot and Ankle Society(AOFAS) ankle-hindfoot score was used to analyze the clinical results of 21 patients with ankle fracture complicating ligament rupture treated by open reduction,intensified internal fixation,and restoration of broken ligaments.ResultsThe ankle joints were strongly surrounded by ligaments.Lateral ligaments were classified as anterior talofibular,calcaneofibular,and posterior talofibular,with the length of(16.89±4.28),(23.12±5.32) and(23.40±5.73) mm,respectively.The medial ligament was a triangle in shape,the length of its anterior,middle,and posterior parts were(20.63±6.24),(15.19±5.43) and(17.16±6.45) mm,respectively.The outcomes of the 21 patients in this study were as follows: good in 16,fair in four,and poor in one.ConclusionLigaments surrounding the ankle are an important structure to maintain a normal function of the joint;the therapy of fracture of ankle accompanying rupture of ligaments by open reduction,internal fixation,repair of injured ligaments,and combined with early and reasonable functional exercises are essential in improving therapeutic effects and preventing traumatic arthritis.
