Background:
Subacromial impingement syndrome is a common orthopedic condition.
Methods:
Patients operated due to shoulder impingement (n=104) were sent a questionnaire inquiring rehabilitation procedures before and after surgery, pain and shoulder function.
Results:
Response rate was 68%, mean age of the patients was 53 years. Before surgery, 50% of the patients had received physiotherapy. The symptoms disappeared after surgery in the majority of the patients. However, 13% of the patients had significant shoulder pain (VAS over 30 mm) one year postoperatively and 15% had considerable functional deficit.
Conclusions:
To avoid unnecessary operations for shoulder impingement proper conservative treatment must be provided before surgery.
