To explore the surgical technique and clinical effect of limited open reduction and intramedullary fixation assisted with orthopedic traction bed for the treatment of femoral subtrochanteric fractures.


From July 2015 to October 2017, 12 patients with femoral subtrochanteric fractures were treated including 9 males and 3 females with an average age of 44 years old ranging from 33 to 67 years old. Among them, 10 cases were on the left trochanter and 2 on the right, and there were 8 cases of highly fall injury and 4 cases of traffic accident injury. All patients received operation at 2 to 5 days after injury. According to the Seinsheimer classification, 8 cases were type IIIA, 2 were type IIIB and 2 were type IV, and all cases were closed injury. The patients were placed on the orthopedic traction bed for trial closed reduction to maintain proper traction before operation. Under C-arm X-ray fluoroscopy, it was advisable to take the fracture end of the main bone block without obvious shortening and shifting. Then limited incision and lengthened InterTan intramedullary nailing were performed, and the Sanders traumatic hip score was used to evaluate the postoperative efficacy.


All 12 patients were followed up from 6 to 24 months with an average of 12 months. All cases were received bone healing at 3 to 6 months with an average time of 4 months. According to the Sanders grades, the results were excellent in 9 cases, good in 2 cases and medium in 1 case. Infection, breakage of internal fixation loosening and adverse complications such as malunion were not appeared in all the cases.


Limited open reduction assisted with traction bed can be effective to solve the problem of the intraoperative reduction in the complex subtrochanteric fractures, which could save operation time and decrease bleeding. Combined with intramedullary fixation, this method could acquire good counterpoint and stability for the fracture end, and provide a method for the treatment of refractory subtrochanteric fractures.
