Problems solved by technology

[0005] Comminuted fractures of the proximal humerus are fixed with locking plates. The fixation of the rotator cuff with bone fragments also relies on suturing the avulsed bone fragments and rotator cuff to the plate. Due to suture cutting, small contact area, and excessive contraction force of the rotator cuff, etc. Lead to re-avulsion, bone fragment fragmentation, displacement and other problems, often due to poor healing of the rotator cuff tissue with bone fragments after suturing or suture cutting, small contact area, excessive rotator cuff contraction force and other reasons lead to re-avulsion, Bone fragmentation, displacement and other problems, after the proximal humeral comminuted fracture healed, the recovery of shoulder joint abduction, flexion, internal and external rotation was not satisfactory

Embodiment 1

[0024] A locking bone plate for the proximal humerus with a hook, comprising a steel plate body 1, three retractors 2 integrally formed on the upper surface of the steel plate body 1, and the three retractors are connected to each other on the side of the steel plate body, the effect of the connection is to increase the contact area , mutual direct and pulling force, when the screw on the locking and pressurizing joint hole 5 is drilled in, the drag hook and the surface of the large tubercle are more fit. The steel plate body 1 is provided with 3 to 4 locking holes 3, and the steel plate body 1 is also provided with 6 gram-type pinholes 4, and 3 gram-type pinholes 4 are distributed on both sides of the locking hole 3, respectively. The length of the steel plate body 1 is 40mm. The steel plate body 1 is also provided with a locking and pressurizing joint hole 5. The function of the locking and pressurizing joint hole 5 is to allow the hook at the upper end to pull down for a bet...

Embodiment 2

[0027] A locking bone plate for the proximal humerus with a hook, comprising a steel plate body 1, three pull hooks 2 integrally formed on the upper end surface of the steel plate body 1, 3 to 4 locking holes 3 are arranged on the steel plate body 1, and There are 8 gram-type pinholes 4, and 4 gram-type pinholes 4 are distributed on both sides of the locking hole 3. The length of the steel plate body 1 is 40mm, and the steel plate body 1 is also provided with 1 locking plus Press the joint hole 5, the lower end of the steel plate body is provided with an extended steel plate 6 integrally formed with it, and the extended steel plate 6 is provided with 3 locking holes 3, the length of the extended steel plate 6 is 40mm, and it is in a fixed position If it is not enough, increase the length of the bone plate, and the three locking holes 3 can basically meet the fixation requirements. The width a of the base of the single draw hook 2 is 6-8 mm, the length of the arc-shaped hook is...

Abstract

The invention relates to a bone fracture plate, and particularly relates to a locking bone fracture plate with hooks for a proximal end of a humerus. Through making the contour of a steel plate abutted with the anatomic forms of a proximal end and a lateral border of the humerus, difficult problems in the therapeutic processes of the avulsion fracture of a greater tubercle of the humerus, the comminuted fracture of the greater tubercle of the humerus and the comminuted fracture of the proximal end of the humerus are solved. The locking bone fracture plate with the hooks for the proximal end of the humerus comprises a steel plate body, wherein the upper end surface of the steel plate body is connected with three drag hooks in an integral molding manner; the three draw hooks are connected with one another and are connected with the side of the steel plate body. The length design of different extending plates is suitable for different therapeutic demands, can be selected and used according to the conditions of different fractures; the shortest locking bone fracture plate with the hooks for the proximal end of the humerus can be operated under a shoulder arthroscopy, and has more advantages for the avulsion fracture and the comminuted fracture of a small piece.

Description

technical field [0001] The invention relates to a bone bone plate, in particular to a locking bone bone plate with a hook at the proximal end of the humerus. Background technique [0002] The reconstruction and fixation of the insertion point of the rotator cuff during fracture operations such as greater tuberosity avulsion fractures, comminuted fractures of the greater tuberosity of the humerus, and comminuted fractures of the proximal end of the humerus are thorny problems. [0003] Avulsion fractures of the greater tuberosity of the humerus are often fixed with screws and locking plates due to osteoporosis, small bone fragments, and excessive contraction force of the rotator cuff, which may lead to problems such as re-avulsion, bone fragment fragmentation, and displacement, resulting in surgical failure. , seriously affecting the postoperative function of the patient. [0004] Comminuted fractures of the greater tuberosity of the humerus are fixed with locking plates. Fi...
