Rotator Cuff Tears
Rotator cuff tears can be a later stage of impingement syndrome, where the rotator cuff tendons tear from their attachment. This usually starts with the supraspinatus and can progress to the infraspinatus or other tendons. Usually this happens over time, but can occur as a single event. It is rare in younger patients, usually after trauma to the shoulder. Pain can be similar to impingement syndrome, but can be associated with more weakness. Other problems such as labral, SLAP, bicep tendon tears, and arthritis can be present.
Non-surgical treatment is similar to impingement with activity modification, avoiding heavy lifting, over the counter medications, and physical therapy. These treatments are more appropriate for partial rotator cuff tears, as painful full tears will usually not respond well to non-operative treatment. It is important that you are examined by an orthopaedic specialist, as Xrays and MRI can confirm a tear. Many times early surgical repair is the best option.
Arthroscopic Shoulder Surgery
Advances in arthroscopic surgery help these problems to be treated with outpatient surgery using minimally invasive techniques. This can result in reduced pain and earlier recovery.
Impingement syndrome is treated arthroscopically with a ‘subacromial decompression’. This involves an outpatient surgery using a few small skin incisions, and the bursa is excised along with any prominent bone spurs. Motion and light use are started early, and physical therapy can help the recovery process.
Rotator cuff repairs are more involved, but these are also treated arthroscopically with outpatient surgery. Small incisions are made and the rotator cuff is reattached to bone arthroscopically. The recovery process involves a step-wise program supervised by a physical therapist and usually lasts 6 months.
