Scapular neck and glenoid fractures

Introduction to scapular neck and scapular fracture The scapula is surrounded by muscles, and the fracture is relatively rare, accounting for about 0.2% of the total body fracture, and the scapula body and neck often occur, often as part of multiple injuries. basic knowledge Proportion of disease: about 0.002% of total body fractures Susceptible people: no special people Mode of infection: non-infectious Complications: fracture

Causes of scapular neck and scapular fracture

(1) Causes of the disease

Such fractures are mostly caused by indirect violence.

(two) pathogenesis

That is, when the fall is on the outside of the shoulder, or the palm is on the ground, the violent warp is caused by the impact of the scapula or the neck. The fire can be directly injured by the firearm injury. The fractures of the external scapular neck are mostly oblique, or interspersed with each other. Mostly, the scapular fracture in the joint is often a partial or comminuted fracture of the ankle. The scapular neck is located on the inner side of the glenoid and moves with the root of the scapula. It has the function of maintaining the normal position and conduction stress of the glenoid. When the fracture is displaced, the normal angle and position of the joint are changed. If the scapular fracture or fracture deformity is healed, the anteversion or caster angle is beyond the normal range, and the ankle joint may be unstable or dislocated.

Scapular neck and scapular fracture symptoms Common symptoms Square shoulder deformity

The appearance of the scapular or neck fracture is not obvious, it is easy to miss the diagnosis, the shoulder and axillary part are swollen, tender, and the pain is increased when the shoulder joint is active. The severely displaced fracture may have shoulder collapse, and the shoulder peak is square shoulder deformity. It is like the shape of the shoulder joint dislocation, but the injured limb has no abduction, adduction, elastic fixation, and the shoulder joint is still active.

Examination of scapular neck and scapular fracture

X-ray examination can rule out shoulder dislocation, diagnosis, CT scan and CT three-dimensional structural reconstruction can clearly show the scapular neck and scapular fracture, and quantify the displacement of the fracture block.

Diagnosis and differentiation of scapular neck and scapular fracture

Diagnostic criteria

History of trauma

Generally speaking, it is more obvious and should be asked in detail.

2. Clinical symptoms

Check the swelling of the shoulders and armpits, tenderness, and increase the pain in the shoulder joint. If the fracture is severely displaced, the shoulder may collapse, showing a "square shoulder" deformity, but there is no joint dislocation.

3. Imaging examination

Conventional X-ray plain film can display the fracture line. If the X-ray is unclear, it is feasible to scan the CT scan or add the oblique slice.

Differential diagnosis

If the fracture is severely displaced, the square shoulder appears and needs to be differentiated from the dislocation of the shoulder joint. At this time, the injured limb has no abduction and elastic fixation.
