RESUMEN
Objective To investigate the clinical effect of surgical treatment of acetabular fractures. Meth-ods According to Letoumel and Judet typing, 17 cases of posterior wall fractures, 5 cases of transverse fractures, 3 cases of anterior wall fractures, 2 cases of anterior column fractures,5 cases of transverse and posterior wall fractures, 2 cases of posterior column and wall fractures, 2 cases of T-type fractures, 1 case of anterior and hemi-transverse fractures and 1 case of fractures of both column). Kocher Langenbeck (K-L) approach was applied in 30 cases, ilio-inguinal approach in 7, and combined approaches (K-L plus ilioinguinal) in 1. Results According to Matta evalua-tion, anatomical reduction(displace < 1 mm) was applied in 30 patients. Satisfactory reduction(displace 2～3 mm) was attained in 6 patients, unsatisfactory reduction(displace >3 mm) was in 2 patients. 38 patients were followed up for 6～48 months (mean: 25 months). The hip function was evaluated according to the modified Postel-D, Aubigne score and rated as excellence in 31 patients(81.5%), good in 5 patients(13.1%), fair in 1 patient(2.6%) and poor in 1 petient(2.6%). The excellent and good rate was 81.5%. Conclusions It is the important guarantee to elevate the therapeutic efficacy of acetabular fracture that shoud be correcdy analyze the fracture displacement and type, choose proper surgical approach, have good restitution implement and operate at the right moment. The quality of surgical reduction has a close correlation with the clinical results.
