Abstract:
OBJECTIVETo investigate the clinical effect of Seinsheimer type V subtrochanteric femoral fractures with dynamic hip screw and shape memory alloy bow-teeth screw.
METHODSTwelve patients with Seinsheimer type V subtrochanteric femoral fractures were retrospectively analyzed. There were 8 males and 4 females with an average age of 53 years (range 31 to 65 years). Seven cases were caused by traffic accident, 4 cases by falling from hight, 1 case by heavy object. According to the Seinsheimer classification, all the cases were type V fractures. All the cases accepted the surgical treatment with dynamic hip screw and shape memory alloy bow-teeth screw fixation.
RESULTSThe mean period of follow-up was 28 months (range 20 to 38 months). All the cases obtained bone union in average 3.3 months (from 3 to 4.5 months). There were no complications such as deep infection, deep vein thrombosis, pulmonary embolism and bone nonunion. The results of clinical evaluation according to Merle d'Aubigne scores were 16.75 +/- 1.14 and excellent in 4 cases, good in 8 cases.
CONCLUSIONApplication of dynamic hip screw and shape memory alloy bow-teeth screw as a superior option can get satisfactory reduction with reliable fixation and will be one of a better choice for fixation of Seinsheimer type V subtrochanteric femoral fractures.
