In order to alleviate the nail body in the intravital weight of people, the front end rigion of described nail body offers the longitudinal fluting of three circumferential five equilibriums.
In order to cooperate different gamma nails to use, back locking nail hole comprises circular back locking nail hole and oval back locking nail hole; Described preceding locking nail hole comprises circular preceding locking nail hole and oval preceding locking nail hole.
Offer two circular back locking nail holes on the rear end section of described nail body.
For can be more firmly and bone fixation, offer two circular back locking nail holes and an oval back locking nail hole on the rear end section of described nail body.
Offer the preceding locking nail hole of two circles on the front end rigion of described nail body.
In order to be fit to different fracture patient and fixing more firm, offer two or three circular preceding locking nail holes and the preceding locking nail hole of ellipse on the front end rigion of described nail body.
Can be fixed in more on the bone simultaneously in order to cooperate screw blade to use, the aperture of described circular knife film perforation is greater than the aperture of preceding locking nail hole and back locking nail hole.
In order to be fit to different femur and intercondylar fracture of the femur person, the shape of nail body is type or be camber linearly.
The material of described nail body is 002Cr
19Ni
13Mo
3Or titanium alloy is made.
The beneficial effects of the utility model are, femoral interlocking nail of the present utility model, and single hole pinning, operation be simple more, and can effectively prevent the splitting of neck of femur in operation process; Be complementary with screw blade, hold-down screw, easier acquisition resets; Can satisfy the needs that neck of femur merges fractured near end of thighbone; Effectively reduce further destruction to femur and intercondylar fracture of the femur.
