Abstract
The invention provides an inner fixing system for a femoral trochanter nail plate. The inner fixing system is a novel inner fixing apparatus and is formed by a femoral interlocking nail engaged with a femoral trochanter steel plate, wherein the femoral trochanter steel plate is an anatomical steel plate which meets the anatomic form of greater femoral trochanter by the crown-shaped surface and the cross section; a chute in the inner side of a pressurizing screw channel on the top end of the femoral trochanter steel plate is higher than a chute in the outer side; a closed screw of the femoral interlocking nail can be screwed to enable the femoral trochanter steel plate to be engaged with the tail of the femoral interlocking nail, and meanwhile, the femoral trochanter steel plate can be horizontally close to the femoral interlocking nail, and therefore, the femoral trochanter steel plate can be in tight contact with greater femoral trochanter. With the adoption of the system, the advantage of outstanding biomechanical stability in fixing of the femoral interlocking nail can be remained, the disadvantage that the greater femoral trochanter suffering from fracture is uneasily fixed and rebuilt can be decreased; a good internal fixing apparatus is provided for treating the fracture in the femoral trochanter area, the operative wound can be reduced, and the surgical treatment effect is improved.
Description
Technical field
The invention belongs to bone surgery set field, specifically, invent a kind of new internal fixation device, while retaining the advantage of the good biological mechanical stability that femoral interlocking nail is fixed, effectively can improve it when being applied to Trochanteric Region complicated fracture, fixingly rebuild the shortcomings such as femoral greater trochanter sclerite difficulty, for the treatment of Trochanteric Region fracture provides better internal fixation device, reduce operation wound, improve the effect of operative treatment.
Background technology
Mainly contain for Trochanteric Region internal fixation device used of fracturing at present: the pegboard systems outside intramedullary nail system and marrow.Intramedullary nail system mainly contains intramedullary nail with lock (PNF)
[1], Gamma nail
[2], anti-revolve near-end intramedullary pin (PNFA)
[3]deng, the pegboard systems outside marrow mainly contains power marrow joint screw (DHS)
[3,4], locking steel plate
[5]deng.Complicated Trochanteric Region fracture, often relates to lateral wall, Trochanteric Region fracture, because the support rib of tuberosity lateral wall loses integrity, does not advise using DHS nail to be fixed
[7].Fracture to the Trochanteric Region of backslash row, the compression aspect of the fracture site that DHS provides and fracture line direction equality, therefore, be more not suitable for using DHS.Femur marrow internal fixation system has good biomechanical stability, and to Trochanteric Region fracture, femoral interlocking nail system (PNF, Gamma nail, PNFA) is good selection; If but when fracturing with femoral greater trochanter lateral wall, fixing being difficult to of simple femoral interlocking nail system is fixed reconstruction to femoral greater trochanter lateral wall simultaneously

Summary of the invention
Goal of the invention: the femoral bone tuberosity nail-plate internal fixation system of this invention, it is the fixed system be engaged by femoral interlocking nail and femoral bone tuberosity steel plate, the advantage of the good biological mechanical stability that femoral interlocking nail is fixed can be retained like this, can be improved again it and be difficult to fracture these shortcomings with fixing reconstruction femoral greater trochanter.
[0005]detailed description of the present invention: femoral bone tuberosity nail-plate internal fixation system is made up of femoral interlocking nail and femoral bone tuberosity steel plate.The forcing screw nail road on femoral bone tuberosity steel plate top and femoral interlocking nail nail tail, be hollow in it, the closed screw of femoral interlocking nail is first followed closely by forcing screw, then enters femoral interlocking nail nail tail, by tightening closed screw, making femoral bone tuberosity steel plate and femoral interlocking nail follow closely tail and being engaged.The inner side chute in the forcing screw nail road on femoral bone tuberosity top is higher than outside chute, therefore, by tightening closed screw, femoral bone tuberosity steel plate and femoral interlocking nail are followed closely while tail is engaged, also femoral bone tuberosity steel plate can be made to draw close to femoral interlocking nail on horizontal position, thus make femoral bone tuberosity steel plate and femoral greater trochanter close contact.The shape of femoral bone tuberosity steel plate designs according to the anatomic form of femoral greater trochanter lateral wall, is anatomical plate, coronalplane and transverse section all meet femoral greater trochanter anatomic form, thus reaches the maximum contact area with femoral greater trochanter.Femoral bone tuberosity steel plate, except the forcing screw nail road on its top, separately has several Universal screw nail nail, can insert screw for fixing Intratrochanter fracture block in it.Femoral interlocking nail in femoral bone tuberosity nail-plate internal fixation system and at present conventional intramedullary nail with lock (PNF) etc. are similar.
The invention has the beneficial effects as follows: by above-mentioned improvement, make femoral bone tuberosity nail-plate internal fixation system, the advantage of the good biological mechanical stability that femoral interlocking nail is fixed can be retained, can be improved again it be difficult to fracture these shortcomings with fixing reconstruction femoral greater trochanter lateral wall, for the treatment of Trochanteric Region fracture provides better internal fixation device, reduce operation wound, thus improve the effect of operative treatment.
