Internal fixation device for treating complex intertrochanteric fracture and application method thereof

Abstract

The invention provides an internal fixation device for treating complex intertrochanteric fractures and an application method thereof, the device comprising a femoral shaft intramedullary main nail, afemoral neck main screw, a lateral steel plate, a femoral neck locking hollow nail, a distal main nail locking nail and a steel plate fixation screw, wherein the femoral shaft intramedullary main nail is inserted into a medullary cavity; the lateral plate is attached to the restored lateral wall of the great tuberosity. At least one femoral neck loc hollow nail is inserted and fix into that femoral head through the first locking hole. The head end of the femoral neck main screw is inserted into the femoral head through the femoral neck after pas through the sliding hole on the middle part ofthe lateral plate and the first lateral hole on the upper part of the femoral shaft main nail. The invention is used for internal fixation treatment of complex intertrochanteric fractures, has the advantages of good internal fixation effect, stability and less failure of internal fixation, and is particularly suitable for complex intertrochanteric fractures with comminuted lateral wall of great trochanter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an internal fixation device for treating complicated intertrochanteric fractures and a method for using it. Background technique [0002] Intertrochanteric fracture is a common clinical fracture, accounting for about 3.9% of all fractures in the whole body. In particular, most patients with intertrochanteric fractures are elderly patients with osteoporosis, often accompanied by serious heart and brain system complications, and if If the fracture cannot be treated in time, the general condition of the patient will often deteriorate rapidly, followed by fatal complications such as penetrating pneumonia and deep vein thrombosis. Therefore, it is one of the most difficult types of fracture in clinical practice. [0003] The applicant finds that the prior art has at least the following technical problems: [0004] At present, there are two fixation methods used in the clini...
