ABSTRACT
Objective To investigate the clinical results and related key points of surgical treatment for Hawkins Ⅲ talus neck fractures.Methods Forty-one patients with Hawkins Ⅲ talus neck fracture were treated.The fractures occurred on the left side in 21 patients and on the right side in 20 patients.All patients were performed internal fixation by internal and lateral approaches.The weight bearing should be adjusted with follow-up.The functional results were evaluated by American Orthopaedic Foot and Ankle Society (AOFAS).Results The average duration of follow-up was (37.7 ± 8.2) months.All fractures gained union and the average union time was (4.1 ±0.5) months.The average AOFAS score after treatment was (79.3 ± 2.6) scores which was higher than that before treatment [(35.1 ± 8.0) scores],and there was significant difference (P =0.026).There were 11 cases in excellent,17 cases in good,11 cases in fair and 2 cases in poor.The excellent and good rate was 68.3％ (28/41).Traumatic arthritis occurred in 18 cases (43.9％,18/41),involved tibial astragaloid joint in 4 cases,involved subtalar joint in 6 cases,involved tibial astragaloid joint and subtalar joint in 8 cases.Avascular necrosis occurred in 7 cases (17.1％,7/41).Conclusions The effect of surgical treatment for Hawkins Ⅲ talus neck fracture via a bilateral approaches is satisfactory.Pay more attention to protect blood circulation intraoperative and perform anatomic reduction according to the characteristic of body of talus displacement.After operation,functional rehabilitation should be directed by the principle of early movement,later weighted.
