History of Changes
  Purpose

Shoulder impingement syndrome is common and number of operations done per year is growing. The aim of this study is to compare the value of arthroscopic subacromial decompression (acromioplasty group) vs. diagnostic arthroscopy (control group) vs. supervised exercise therapy (conservative group) on subjects with chronic subacromial impingement syndrome. The results of treatment are measured at 3 months, 6 months, 12 months and 24 months. Main outcome measures are Pain at rest and activity (VASs), functional assessment of the shoulder with Constant score and Simple Shoulder test (SST), global assessment of change , quality of life assessment (SF-36 and 15D) and costs.

Criteria

Inclusion Criteria:

In the first phase orthopaedists select consecutive female or male patients who are admitted to the hospital policlinic of Helsinki University Hospital, (either Töölö Hospital or Jorvi Hospital) or District Hospital of Tampere (Hatanpää Hospital) and fulfil the following inclusion criteria:

  1. Subjects are 35 to 65 years of age female or male and have a characteristic history and symptoms of subacromial impingement syndrome at least 3 months.
  2. Symptoms have no relieved with appropriate conservative treatment (i.e. physiotherapy, NSAIDs and subacromial corticosteroid injection).
  3. They have clinical findings of impingement syndrome; painful arc sign and pain in shoulder abduction, positive findings in two of three isometric shoulder abduction tests (0 degree, 30 degree and external rotation), and positive subacromial injection test.

Exclusion Criteria:

  1. Previous surgery of affected shoulder
  2. Symptomatic osteoarthrosis of acromio-clavicular joint
  3. Full thickness rotator cuff tear based on clinical findings and MRI
  4. Long-term cervical syndrome
  5. Instability of shoulder
  6. Reluctance to participate in any study groups (i.e. any treatment options of the study)
  7. Reduced co-operation (drug or alcohol abuse, mental illness)
