Malalignment of the shoulder after stroke.

Area of Science:

• Neurology
• Radiology
• Orthopedics

Background:

• Stroke often leads to immobility and potential complications.
• Shoulder issues are frequently observed in stroke survivors, impacting rehabilitation.

Purpose of the Study:

• To investigate the incidence and timing of radiographic shoulder malalignment in stroke patients.
• To identify factors contributing to shoulder malalignment post-stroke.

Main Methods:

• Prospective study of 110 consecutive stroke unit admissions.
• Radiographic assessment of shoulder alignment on the affected side.
• Follow-up imaging over 12 months.

Main Results:

• 46% of patients exhibited shoulder malalignment.
• 37% showed malalignment on initial X-rays; 14% developed it within 12 months.
• Malalignment may be missed without erect, unsupported arm radiography.

Conclusions:

• Shoulder malalignment is a frequent early complication of stroke.
• Early detection and intervention are crucial for preventing functional deficits.
• Proper patient handling, positioning, and passive range of motion are key preventive measures.
