ABSTRACT

Objective To explore clinical effect of surgical treatment of displaced intra-articular calcaneal fractures via modified lateral L-shaped incision.Methods From January 2005 to October 2011,133patients (143 feet) with displaced intra-articular calcaneal fractures,including 125 males and 8 females,aged from 19 years to 65 years (average,43.2 years),underwent open reduction and internal fixation via modified lateral L-shaped incision.There were 56 cases of left calcaneal fractures,67 cases of right calcaneal fractures,and 10 cases of bilateral calcaneal fractures,and all of them were closed fracture.According to Sanders classification,15 feet were classified as type Ⅱ,107 type Ⅲ,and 21 type Ⅳ.The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale were used to access outcomes.Results One hundred and twenty five patients (135 feet) were followed up for 12 to 28 months (average,18.5months).All fractures healed after an average of 13 weeks (range,8-16 weeks).There were on nerve injury or osteomyelitis.Incision dehiscence occurred in 4 feet,which healed after removing the plate.Subtalar joint traumatic arthritis occurred in 17 feet,with walking pain.Collapse of articular surface occurred in 5 feet after weight-bearing.According to AOFAS ankle-hindfoot scale,excellent result was got in 94 cases,good in 29 cases,fair in 14 cases,poor in 6 cases; and the excellent and good rate was 92.9％.Conclusion Open reduction and internal fixation via modified lateral L-shaped incision for treating displaced intra-articular calcaneal fractures can obtain satisfactory results,but the skilled surgical techniques are needed.
