Abstract

Background: Distal clavicular fracture is a shoulder joint injury that is common in clinical settings and is generally surgically treated using the clavicular hook plate technique with a confirmed curative effect. However, symptoms, such as shoulder abduction limitation, shoulder discomfort, and postoperative joint pain, may occur in some patients. To overcome these problems, after a previous study we developed an acromial height-measuring device and a new type of clavicular hook plate. This study aimed to investigate whether an acromial height-measuring device combined with an improved new-type clavicular hook plate can better reduce the incidence of complications and improve postoperative function. To provide patients with better treatment effects, an acromion gauge and clavicular hook plate are used.

Methods: A retrospective analysis was performed on 81 patients with distal clavicular fractures admitted to our hospital. They were divided into experimental and control groups according to different plates, and the Constant-Murley score, visual analogue scale score, incidence of acromion osteolysis, and incidence of subacromial impingement syndrome were compared.

Results: Compared with the standard clavicular hook plate, the acromial height-measuring device combined with the new-type clavicular hook plate in the treatment of distal clavicle fractures has a lower incidence of subacromial impingement syndrome with better postoperative functional recovery and quality of life.

Conclusions: We considered the acromial height-measuring device combined with the new clavicular hook plate to be a safe and promising alternative to distal clavicular fractures.

A shoulder height-measuring device developed by our team. The shape of the measuring instrument matches the hook plate currently used. The third picture is a physical object that has been used in clinical practice. During the operation, the c side is placed at the distal end of the clavicle, and the d side is placed under the acromion, and the height of the acromion is measured

In the past, the end hole of the hook steel plate was a 3.5 mm joint hole, but now it is changed to seven 2.7 mm universal holes. The hook angle of the hook steel plate in the past was 90°, and now a 110° steel plate is added

The patient's preoperative X-ray showed that the bone continuity of the right distal clavicle was interrupted; we chose to use the new-type hook plate fixation, which avoided the fracture line well and made the fixation firm
