ObjectiveTo evaluate the clinical results of proximal femur locking compression plate(LCP)for unstable four-part intertrochanteric femoral fractures.MethodsClinical data of 53 patients wiith unstable four-part intertrochanteric fractures from July 2005 to May 2010 were analyzed retrospectively.All the cases were treated with proximal femur LCP.The results were assessed radiographically according to the neck-shaft angle of the femur(collodiaphysial angle)and the tip-apex distance.Clinical evaluation was made using the Harris hip score.ResultsFifty-two patients were followed up for an average of 9.1 months(range from 3 months to 24 months).U-nion was obtained in all the patients.Reduction was good in 49 patients，acceptable in 2 patients，and poor in 1 patient.The mean collodiaphysial angle was 129°(range 93°to 138°).There were 47 patients whose tip-apex distances were less than 25 mm，and 5 patients whose tip-apex were greater than or equal to 25 mm.Post-operative complications included 2 cases of varus，1 case of traumatic ossification and 2 cases of meralgia.Acccording to Harris hip score，the results were excellent in 29 patients，good in 19 patients，fair in 3 patients，and poor in one patient，with the excellent-to-good rate 92.3% .ConclusionConsidering the anatomic structure of proximal femur，stabilization and anti-rotation function，safety and flexible operation，short operation time，blood loss decrease and less disturbance to blood supply of femur head，proximal femur LCP is a comparable internal fixation device for unstable four-part intertrochanteric femoral fractures.21 refs，2 figs，2 tabs.
