Description
Technical field
The present invention relates to a kind of intertrochanteric fracture of the femur external fixer, particularly a kind of outer fixedly locked pegboard systems for the treatment of intertrochanteric fracture of the femur weak and sickly, osteoporotic elderly population that is applicable to, belongs to Fracture of femur technique for fixing field.
Background technology
Proximal femur comprises femoral head, neck of femur and big or small tuberosity.By neck of femur substrate with as far as little tuberosity level with fracture that upper part was occurred, be referred to as intertrochanteric fracture of the femur, be more common in 60 years old above old people, because of senile osteoporosis, while falling, lower limb reverse suddenly or sharply hyper-abduction or interior receipts, or external force is directly impacted greater trochanter and can be fractured.The treatment of intertrochanteric fracture of the femur is one of the most challenging treatment of orthopaedic trauma field, and approximately 30% old people is associated with serious Medicine Systems disease, if take expectant treatment, its bed rest time is long, and nursery work is loaded down with trivial details, and whole body organ function is obviously influenced.Fracture is difficult to obtain good reset and maintains for a long time reset.Causing thus or increase the weight of the sick state of an illness of patient's original base, is to cause the high main cause of Treatment of Intertrochanteric Fractures in Aged Patients expectant treatment case fatality rate.Therefore, the operative treatment of senile human femur intertrochanteric fracture that actively creates conditions has become the widespread consensus of orthopaedic trauma.
The therapeutic method of surgery of Fracture of femur is many, comprising: 1, fixing in closed many steinman pins: to use 4 pieces of diameter 3.5mm steinman pins with many steinman pin fixationes of fracture of femoral neck.2, fixing in nail-plate class: the method all kinds fracture that is applicable to be grown up, is fixed with DHS(dynamic property hip screw in conventional) and Charnley slip add nail pressing etc.3, Gamma nail is fixing: i.e. an intramedullary nail with nail, and tiltedly wear one and follow closely by femoral head and neck coarse screw, because main nail passes through pulp cavity, from biomechanical analysis, the line of force is close to femoral head center, and larger stress can be born in Gamma nail femur inner side, can reach the object of bearing a heavy burden down in early days.4, locking steel plate is fixed: the internal fixation steel plate of up-to-date release, the technique of locking steel plate uniqueness makes it be not only the effect of internal fixation steel plate, and many effects of inner fixed support, steel plate and surface of bone leave certain distance, the blood circulation of bone is improved relatively, but it is weaker that plate is dismissed in existing near end of thighbone locking, and clinical practice interruption board moves back nail and causes the incidence rate of interior solid failure high.5, PFNA: it belongs to a kind of Novel thighbone near-end internal fixation system, it is new improved PFN (PFN) system, inherited on the one hand the advantage of former PFN, there is rotation preventing function, for various types of intertrochanteric fractures and high-order fractura subtrochanterica, PFNA afterbody is thick, and diameter, at 14～16mm, can cause near end of thighbone bone loss in implantation process.Above Therapeutic Method all needs open operation, wound is larger, and operation and apparatus somewhat expensive, the row operation that needs after union of fracture to be again in hospital is taken out, the elderly population that is associated with cardiovascular and cerebrovascular disease can not open operation, its family members often refuse open surgery scheme, passive selection expectant treatment.Exterior fixation bracket does not need open surgery, and still the thick clumsiness of existing exterior fixation bracket, is inconvenient to nurse, and existing apparatus and method are not the optimum selections to Treatment of Intertrochanteric Fractures in Aged Patients.For this reason, with regard to advantage fixing inside and outside a kind of combination of necessary design, fixation, do not need open operation, little to patient's wound, patient suffering is few, the intertrochanteric fracture of the femur that do not need open surgery to take out, just can remove in minor operation room, economic costs is few outer fixedly locked pegboard systems.
Summary of the invention
The object of the invention is to provide in order to overcome the deficiencies in the prior art a kind of outer fixedly locked pegboard systems for the treatment of intertrochanteric fracture of the femur that is more suitable for elderly population.
In order to achieve the above object, technical scheme of the present invention is: a kind of outer fixedly locked pegboard systems of intertrochanteric fracture of the femur for the treatment of, is characterized in that: comprise femur lockplate; The top of described femur lockplate is upper plate portion, and the bottom of femur lockplate is lower board unit; The inner surface of described femur lockplate forms a shape similar to the large leg outer side skin contours of human body; The middle part of described upper plate portion is provided with main lock hole and lower main lock hole; Described main lock hole is positioned at the top of lower main lock hole; The top of described upper plate portion is provided with upper secondary lock hole along centrage, and the bottom of upper plate portion is provided with lower secondary lock hole along centrage; On described lower board unit, along centrage, be provided with lower lock hole; Described main lock hole, lower main lock hole, upper secondary lock hole, lower secondary lock hole, lower lock hole are counter sink, and the countersunk head position of described counter sink is all positioned on the outer surface of femur lockplate, and the throughhole portions of described counter sink is provided with female thread; Described main lock hole, lower main lock hole, upper secondary lock hole, lower secondary lock hole, lower lock hole respectively correspondence are equipped with main locking nail, lower main locking nail, upper secondary locking nail, lower secondary locking nail, lower locking nail; Described main locking nail, lower main locking nail, upper secondary locking nail, lower secondary locking nail, lower locking nail all comprises and the first threaded portion of the screw-internal thread fit of described counter sink, be screwed into the second threaded portion of femoral head inside and be arranged on the first threaded portion and the second threaded portion between the light screw rod that is screwed into the skin and flesh tissue outside femur; The screw thread of the second threaded portion of described main locking nail, lower main locking nail is coarse thread.
Preferably, the screw thread of the second threaded portion of described secondary locking nail and lower secondary locking nail is coarse thread.
The outer fixedly locked pegboard systems for the treatment of intertrochanteric fracture of the femur of the present invention, the lockplate of thickening is placed in Ipsilateral thigh near-end skin outside, by the screw-nut mode between screw what lockplate, connect that to reach nail-plate integrated, prevent that screw loosening from coming off, angle good stability, good fixing effect, outside plate and hip, docile is good, does not affect postoperative patient and wears trousers, and wrapping nursing is convenient, operation wound is little, and after union of fracture, outpatient service just can complete and take out operation.For being associated with serious internal disease, can not accept open surgery, have unsuitable long-term bed gerontal patient, adopt a kind of selection of can yet be regarded as of the outer fixedly locked pegboard systems of this treatment intertrochanteric fracture of the femur.Gerontal patient's activity is little, uses after outer fixedly locked pegboard systems resected femur intertrochanteric fracture, can early ambulant, reduce complication, and improve the quality of living.
