AI Technical Summary
When treating greater tuberosity fractures of the humerus, especially in elderly patients, existing technologies use screw fixation alone but lack sufficient fixation strength, resulting in the need for long-term fixation of the shoulder in the abduction position after surgery, increasing the risk of surgical failure. In addition, the fixation effect is not ideal when dealing with multiple fracture fragments or comminuted fractures, resulting in a long recovery period and the risk of complications.
A porous and easily moldable hook plate for the greater tuberosity of the humerus is designed. It contains multiple locking rings and adjustment rods. When used with a universal nail, it can be precisely fixed according to the fracture situation and shaped through the adjustment rod connection to closely fit the anatomical morphology of the greater tuberosity of the humerus, thereby increasing the fixation area and stability.
It achieves precise fixation of multiple fracture fragments and comminuted fractures of the greater tuberosity of the humerus, improves the fixation effect and stability, shortens the recovery period, and reduces the occurrence of complications.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a porous and easily plastic hook plate for the greater tubercle of humerus. Background Art
[0002] Currently, fractures of the greater tuberosity of the humerus are a common type of fracture in clinical practice, and screw fixation is often used for its treatment. However, due to the relatively porous bone in the greater tuberosity of the humerus, especially in elderly patients, the use of screw fixation alone often lacks sufficient fixation strength. Postoperatively, the shoulder needs to be fixed in the abduction position for a long time to prevent the fracture from displacing again or cutting between the screw and the bone fragment, which increases the risk of surgical failure. In addition, when treating complex fractures of the greater tuberosity of the humerus, such as multiple fracture fragments and comminuted fractures, the existing technology is often not ideal in terms of fixation effect due to irregular fracture lines and scattered fracture fragments. The recovery period is long and complications are prone to occur.
[0003] Therefore, their structural design and fixation effect still need to be improved to better adapt to different types of fractures and the anatomical structures of different patients, provide stronger fixation force, and promote rapid recovery of patients. Utility Model Content
