Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a fixing device for preventing shoulder joint subluxation. Background Art

[0002] Glenohumeral subluxation (GHS), also known as malaligned shoulder, is common in patients with hemiplegia. It manifests as the humeral head sliding down within the glenoid fossa, with a noticeable depression forming between the acromion and the humeral head. GHS may be associated with shoulder pain in hemiplegic patients and may be accompanied by brachial plexus injury, making it a sign of poor upper limb prognosis. Reported rates of GHS vary widely (0-80%), with most cases ranging from 30% to 50%. Shoulder subluxation does not occur immediately after hemiplegia; it is often discovered after the onset of sitting and other activities within the first few weeks after the onset of symptoms. Its primary causes are incorrect upper limb positioning and excessive stretching of the affected upper limb in the early stages of the disease.

[0003] Patients in the early stages may not feel any discomfort. Some patients may experience pulling discomfort or pain due to gravity when the affected upper limb hangs at the side of the body for a long time. When the upper limb is supported or lifted, the above symptoms may be alleviated or disappear. As time goes on, more severe shoulder pain may occur, and those with combined shoulder joint restriction are more likely to experience it than those without subluxation. When the shoulder joint is subluxated, the shoulder joint cannot provide a stable foundation for upper limb control, so its preventive rehabilitation treatment is a key factor in the functional rehabilitation of the upper limbs. In order to prevent the aggravation of shoulder subluxation, a shoulder brace that prevents joint subluxation is worn, but the currently available shoulder brace does not provide stable support for the joint, which makes the effect of slowing down the prevention of shoulder subluxation poor, and does not have the effect of prevention and treatment.
