Embodiment Construction

[0016] Such as figure 1 figure 2 image 3 As shown, a claw-shaped large trochanteric locking bone plate with flanks includes an arc-shaped plate body 9 and a vertical plate body 8. The lower end of the arc-shaped plate plate is connected with the upper end of the vertical plate body 8 to form an integrated structure. The top of the plate body 9 is provided with two hook plates 1 for enhancing the stability of fixation with the greater trochanter. Therefore, the hook plates 1 can effectively resist the strong abduction force of the muscles.

[0017] Two upper flank plates 2 are respectively arranged on both sides of the arc-shaped plate body 9, and two first screw holes are arranged on each upper flank plate 2, and the upper side wall plates can be bent or cut off, and the mm locking screws or cortical bone screws can provide reliable support to the anterior and posterior sides of the greater trochanter when targeting comminuted fractures.

[0018] On both sides of the lowe...

Abstract

The invention discloses a claw-shaped greater trochanter locking bone fracture plate with side wings. The locking bone fracture plate comprises an arc plate body and a vertical plate body, wherein the lower end of the arc plate body is connected with the upper end of the vertical plate body as an integral structure; two hook plates used for enhancing the fixing stability of the arc plate body and a greater trochanter are arranged at the top end of the arc plate body; one or more upper side wing plates are arranged on the two sides of the arc plate body; a plurality of first bolt holes are formed in the upper side wing plates. Through the adoption of the wing plates arranged on the upper side and the lower side, utilization of the cable is not needed when a doctor uses the bone fracture plate to conduct bone-setting positioning; moreover, by arranging locking bolts on the wing plates for fixing, the aims of fixing the lesion parts safely, simply, practicably, economically and effectively are achieved.

Description

technical field [0001] The invention relates to a claw-shaped large trochanter locking bone plate with flanks. Background technique [0002] Simple or complex greater trochanteric fractures, Vancouver type A periprosthetic fractures, greater trochanteric osteotomy, and trochanteric pseudarthrosis / nonunion are common clinical cases. The current surgical treatment method is mainly to implant the greater trochanter bone plate in the lesion. However, most of the internal fixation products currently on the market are bone plates and cables, which are cumbersome to operate, require large surgical incisions to expose additional parts, are expensive, and are especially difficult to operate on patients with comminuted fractures and osteoporosis. Therefore, it is necessary to develop a safe, simple, practical, economical, and effective locking plate for the large trochanter with flank claws. During the operation, select the corresponding locking hole and insert the locking screw to s...
