Abstract:

BACKGROUND: Strict requirement of the reduction after talar fracture and susceptibility to blood supply dysfunction in talus are two main problems for the treatment of talar fracture, which is also called two balance points. On one hand, talar fracture needs precise reduction; one the other hand, blood supply in the talus should be protected.
OBJECTIVE: To explore therapeutic effect of internal or external malleolus osteotomy using absorbable screw or absorbable stick for talar fracture.
METHODS: From June 2008 to June 2011, 16 patients of talar fracture were treated with internal or external malleolus osteotomy. The talus was fixed using absorbable screw or absorbable stick, and refixed with steel plate or cannulated screws after reduction of internal or external malleolus. The blood supply should be protected during the operation. Internal incision was derived from the anterior border of medial malleolus to tubercle of scaphoid bone, between tibialis anterior and tibialis posterior muscle, avoiding the great saphenous vein. The rest blood supply of the talus which resided in the triangular ligament area should also be protected. When cleaning bone fragments, the drills and screws should not be close to subtalar joint, avoiding injury in the vascular network 
of tarsal sinus and the artery in tarsal tunnel. Based on the patient’s chief complains, clinical efficacy was evaluated through detections of ankle joint appearance and function, X-ray and CT scanning. The therapeutic effect was assessed with Hawkings scoring system.
RESULTS AND CONCLUSION: The involved 15 patients were followed up for 25-36 months. According to the modified Hawkings, 8 patients (53%) were rated as excellent, 5 patients (33%) good, 1 (7%) fair and 1 (7%) poor, the total rate of being excellent and good was 86%. Operation through approach of internal or external malleolus osteotomy using absorbable screw or absorbable stick is a good method for treatment of talar fracture.
