Abstract: ［Abstract］〓Objective〖HTSS〗〓To evaluate the surgical skills and curative effect of anterograde intramedullary nailing(IMN) in the treatment of displacement femoral shaft fractures(FSFs) under the assistance of an reduction device by percutaneous joystick techniques.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓The 76 adult patients with unilateral displacement FSFs were enrolled into this study and were randomly divided into control group(39 cases) and observation group(37 cases). The patients of control group were treated with IMN using conventional methods to reduce femoral shaft fracture. The patients of observation group were treated with IMN via a novel percutaneous technique that employs T tape pin reduction device which used as a “joystick” to align the femoral shaft fractures. The operation time, fluoroscopy time, and intraoperative blood loss of two groups were compared. Followup was conducted to assess the healing time of the fractures and the functional recovery of the affected limbs.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓All the fractures were reduced in the closed fashion in observation group under the assistance of T tape pin reduction device. In control group, 4 cases were reduced via open reduction. The operation time, reduction time, fluoroscopy time and intraoperative blood loss in observation group was significantly less than that in control(P＜005). The fracture union time and functional recovery between groups were no significant differences(P＞005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The displacement FSFs treated with IMN under the assistance of the T tape pin redaction device by percutaneous techniques is a good choice with the advantages of rapid reduction, short operative time, less intraoperative blood loss, less fluoroscopy time and excellent functional recovery, so it is worthy of popularizing in clinic.
