Coracoid pectoralis minor syndrome

Introduction to the condylar chest muscle syndrome After the condyle and the pectoralis minor muscle passed through the neurovascular bundle to the upper limb, Wright discovered in 1945 that the normal person had an oppression of the neurovascular bundle when the upper extremity was excessively abducted, because the neurovascular bundle was tightened while receiving the chest. Caused by the compression of small muscles. The part of the compression site that transitions to the radial artery in the subclavian artery can demonstrate the mechanism of this compression on both the anatomical specimen and the operating table. basic knowledge The proportion of illness: 0.025% Susceptible people: good for young people Mode of infection: non-infectious Complications: periodic limb dyskinesia

Causes of condylar chest muscle syndrome

Under normal circumstances, excessive abduction of the upper extremity, although the vascular nerve bundle is compressed, but does not show symptoms, and when the condylar fracture is malformed or the pectoralis minor muscle is thickened, symptoms appear because the nerve vascular bundle is tightened. At the same time, it is caused by the compression of the pectoralis minor muscles, and the compressed part is in the part of the radial artery that transitions to the radial artery.

Prevention of condylar chest muscle syndrome

There is no effective preventive measure for this disease, and the work may be relieved if the work is changed. Massage has a certain effect.

Complications of condylar chest muscle syndrome Complications, periodic limb movement disorders

Patients with this disease may have tenderness of the lower thoracic muscles of the condyle. After pressurization, the forearms, hands, fingers, numbness, tingling and other symptoms may be present, and there are fewer reports of complications.

Symptoms of condylar chest muscle syndrome Common symptoms Finger or arm thorn... Hand and fingers full of muscle tenderness

The disease occurs in young people with muscular, short, and thick neck, more than the onset of work, fullness of hands and fingers, numbness and tingling in the forearms and fingers. The most obvious sign is the tenderness of the small chest muscles under the condyle. After compression, the forearm, hands, fingers, numbness, tingling and other symptoms can be repeated. Excessive abduction of the affected limb can block the pulsation of the radial artery.

Examination of condylar chest muscle syndrome

The disease can be diagnosed according to the clinical manifestations. X-ray examination is often used for the auxiliary examination. X-ray examination can be used to find the phenomenon of compression of the small chest muscles under normal circumstances.

Diagnosis and differentiation of condylar chest muscle syndrome

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

Pectoralis minor muscle syndrome and cervical rib syndrome, anterior scalene syndrome, rib lock syndrome, and excessive abduction syndrome, now collectively referred to as upper thoracic syndrome, the difference between this disease and cervical spondylotic radiculopathy Procaine solution can be used to seal at the tender point (the front bevel muscle point). If it is cervical spondylosis, the symptoms disappear after partial closure. If the upper thoracic syndrome is present, the supraclavicular artery and supraclavicular vein compression symptoms remain unchanged.

As a kind of upper thoracic syndrome, this disease needs to be distinguished from the following diseases: carpal tunnel syndrome, ulnar nerve tube syndrome, scapular sleeve disease, acral paresthesia, cervical spondylosis, syringomyelia, muscular atrophy Lateral sclerosis, progressive muscular atrophy and lung sulcus syndrome (pulmonary lobes involving the brachial plexus, visible shadows at the tip of the lung).
