Technical Field

The utility model relates to the technical field of orthopedic medical equipment, in particular to a femoral neck inner side supporting bone fracture plate device with side wings.

Background

Femoral neck fracture refers to fracture from the femoral head to the base of the femoral neck, and is a type of fracture which is common in clinic and frequently occurs in the elderly. The incidence rate of femoral neck fracture is high, which accounts for about 3.6 percent of the total fracture and 60 percent of the hip fracture. As one of the common clinical fracture types, the incidence rate is remarkably increased along with the accelerated development of industry and traffic in the aging process of population. The patient with proximal femoral fracture has difficulty in moving, so that much pressure is brought to the family of the patient, and femoral neck fracture often occurs in the elderly. Along with the prolonging of the life of people, especially along with the gradual aging of population structures, the incidence of femoral neck fractures is gradually increased, the femoral neck fractures are treated by the conservation treatment and the operation treatment, the conservation treatment is only suitable for partial cases without obvious displacement, the conservation treatment time is long, and the diseases are more.

SUMMERY OF THE UTILITY MODEL

Further, the body is a straight plate type bone fracture plate.

Furthermore, the bone fracture plate is arranged in a bending mode in the length direction and the bending shape of the bone fracture plate is matched with the inner side bending radian of the femoral neck, the bone fracture plate is arranged in a bending mode in the width direction, and the surface of the bent bone fracture plate is matched with the inner side surface shape of the femoral neck.

Furthermore, the number of the locking screw holes is two, and the number of the long round holes and the number of the round holes are one.

Furthermore, the included angles between the axes of the oblong hole and the locking screw hole and the body part are different.

The utility model discloses realize following beneficial effect:

1. the utility model discloses broken through traditional method of fixing from thighbone lateral surface tension side, take to fix from the fracture pressure side, increase the inboard support mechanical properties of thighbone neck, the shearing force that the thighbone neck bore of antagonism patient when bearing a burden, avoid thighbone neck fracture to take place relative displacement under the longitudinal stress effect, two flanks of setting can wrap up thighbone neck one-third down, do squatting at the patient, when starting, play anti femoral head because of the effect that takes place rotary displacement with the acetabular bone friction, maintain fracture stability, be favorable to fracture healing.

2. The utility model discloses a alar part does not set up the screw hole, does not beat the screw, does not disturb the endwise slip pressurization of femoral neck fracture healing in-process, is favorable to the fracture healing, has effectively avoided traditional femoral neck fracture to use the shortcoming of hollow nail alone, has avoided the shortcoming of interior backup pad in the past.

3. The utility model discloses a somatic part sets up slotted hole and locking screw, there is angle stability in the terminal locking screw of somatic part, but the screw that the slotted hole internal lock advances is fixed with the pressurization, make coaptation board and the inseparable laminating of femoral neck medial edge, increase the anti-shear performance of coaptation board, the slotted hole that the somatic part set up can also make the screw diversion, avoid twisting the femoral neck with by the outside to inboard parallel, the hollow nail of three inverted triangle distributions of head is crossed mutually, put the nail in the convenience art, can improve femoral neck fracture back stability, promote union of fracture, prevention or avoid taking place femoral head necrosis.

Drawings

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.

Fig. 1 is a schematic plan view of the present invention.
