The orthopaedic surgeon has a multitude of internal fixation devices and techniques available for use in the treatment of subtrochanteric fractures of the proximal femur. The successful use of second-generation locking nails is technically demanding. Close attention to positioning of the patient, reduction of the fracture, placement of the guide-wire, and insertion of the nail and of the proximal and distal locking screws is mandatory. The newer, high-strength hip-screws allow good fixation of a fracture that extends into the piriformis fossa. If medial comminution is present, this technique is best performed in conjunction with indirect reduction and bone-grafting. With proper technique, these devices allow the surgeon to manage predictably a complex subtrochanteric fracture that previously had to be treated with traction or extensive dissection and with (frequently inadequate) internal fixation.
骨科医生有多种内固定装置和技术可用于治疗股骨近端转子下骨折。第二代锁定钉的成功使用对技术要求很高。必须密切关注患者的体位、骨折复位、导丝置入、髓内钉以及近端和远端锁定螺钉的插入。新型高强度髋螺钉能很好地固定延伸至梨状窝的骨折。如果存在内侧粉碎,该技术最好与间接复位和植骨联合应用。采用适当的技术,这些装置能让外科医生可预测地处理复杂的转子下骨折,而这种骨折以前必须通过牵引或广泛解剖以及(常常效果不佳的)内固定来治疗。
