Limited shoulder movement

Introduction Shoulder activity is limited, more common in the inflammation around the shoulder joint and shoulder dislocation. Periarthritis around the shoulder is mainly due to adhesion of joint capsules, ligaments, muscles, etc. The most common symptom of joint dislocation is dysfunction. Dislocation of the shoulder joint is the most common, accounting for about 50% of the dislocation of the whole body. This is related to the anatomical and physiological characteristics of the shoulder joint. For example, the humeral head is large, the joint is shallow and small, the joint capsule is slack, and the front and lower tissues are weak. Big, there are many opportunities to suffer from external forces.

Cause

1. Trauma of the shoulder joint leads to dislocation of the shoulder joint.

2, inflammation around the shoulder joint: most of the disease occurs in the elderly over 40 years old, soft tissue regression lesions, the ability to withstand the weakening of various external forces is the basic factor; long-term excessive activity, poor posture caused by chronic damage is The main cause of the attack.

3, after the upper limb trauma, the shoulder is fixed for too long, the shoulder tissue is secondary to atrophy and adhesion.

4, acute contusion of the shoulder, improper treatment due to improper treatment.

1, history of shoulder trauma, chronic strain, fracture history, long-term fixed medical history, etc., combined with shoulder pain, activity disorders and so on.

2, X-ray examination: can diagnose the dislocation of the shoulder joint; it also has a certain diagnostic effect on the inflammation around the shoulder joint, mainly showing the blur deformation and even disappearance of the fat line under the shoulder. The soft tissue contrast is reduced, and the fat line under the shoulder is blurred and even disappeared. Calcification of the soft tissue of the shoulder, in addition, osteoporosis, joint hyperplasia or formation of osteophytes or narrowing of joint space in the acromioclavicular joint.

Differential diagnosis

Restriction of shoulder joint activity needs to be identified as follows:

Periarthritis around the shoulder, also known as leaking shoulder wind, fifty shoulders, frozen shoulder, referred to as shoulder periarthritis, is a common symptom of shoulder joint pain and mobility inconvenience. The prevalence of this disease is around 50 years old, and the incidence rate of women is slightly higher than that of men, which is more common in manual workers. If you do not get effective treatment, it may seriously affect the functional activities of the shoulder joint and hinder daily life. In the early stage of the disease, the shoulder joint showed paroxysmal pain, which was often induced by weather changes and fatigue. Later, it gradually developed into persistent pain, and gradually increased, sputum light and heavy, night can not be paralyzed, can not lie on the side of the affected side, shoulder joint Active and passive activities in all directions are limited. When the shoulder is pulled, it can cause severe pain. The shoulder joint can be extensively tender and radiate to the neck and elbow, and there can be varying degrees of deltoid atrophy.

Traumatic anterior dislocation of the shoulder has a significant history of trauma, shoulder pain, swelling and dysfunction. The injured limb is elastically fixed in the mild abduction internal rotation, elbow flexion, and the affected side forearm is supported by the contralateral hand. The appearance is a "square shoulder" deformity, the shoulder peak is prominent, and the shoulder is empty. The humeral head can be touched under the armpits, under the condyles or under the collarbone. Mild abduction of the injured limb can not be close to the chest wall. If the elbow is attached to the chest, the palm cannot touch the opposite shoulder at the same time (Dugas sign, that is, the shoulder test is positive). The upper arm is placed on the outside of the upper arm to simultaneously contact the acromion and the external iliac crest (straight rule test). X-ray examination can determine the type of dislocation and determine the presence or absence of fracture.
