In shoulder impingement syndrome, the rotator cuff tendons and bursa become compressed and irritated under the acromion process of the shoulder blade. Arthroscopic subacromial decompression involves removing bone and soft tissue to create more space and reduce impingement[1][3].

Removing Bone Spurs and Inflamed Tissue

During the arthroscopic procedure, the surgeon uses small instruments to remove any bone spurs on the underside of the acromion that may be causing impingement. The inflamed bursa is also removed to reduce pressure on the rotator cuff[1][3].

Minimally Invasive Approach

Arthroscopic surgery is minimally invasive, requiring only small incisions. The surgeon inserts a tiny camera (arthroscope) to view the inside of the shoulder joint on a monitor. Surgical instruments are then inserted through other small incisions to perform the decompression[2][4].

Faster Recovery and Less Pain

Compared to open shoulder surgery, arthroscopic subacromial decompression results in less tissue damage, reduced pain, lower infection risk, and faster recovery times[2]. Patients can often begin rehabilitation exercises soon after surgery to regain range of motion and strength[3].

Improved Outcomes

Studies show that arthroscopic subacromial decompression significantly improves shoulder function and reduces pain in patients with impingement syndrome[4]. Over 80% of patients achieve good to excellent outcomes at 6 months post-surgery[4].

In summary, arthroscopic shoulder surgery, particularly subacromial decompression, is an effective minimally invasive treatment that decompresses the space under the acromion, removes irritating bone and tissue, and results in faster recovery and improved shoulder function for patients with impingement syndrome.
