Randomized Controlled TrialSubacromial bursa block is an effective alternative to interscalene block for postoperative pain control after arthroscopic subacromial decompression: a randomized trial.
Subacromial decompression surgery is associated with significant postoperative pain. We compared interscalene block (ISB) with subacromial bursa block (SBB). Sixty consecutive patients with subacromial impingement syndrome, scheduled for arthroscopic subacromial decompression surgery, were randomized into 3 groups receiving ISB (n = 19), SBB (n = 19), or no block (n = 15 [controls]). ⋯ The time to first bolus was earlier in the control group (mean, 42.1 minutes) compared with both the SBB (mean, 92.6 minutes) and ISB (mean, 119.0 minutes) groups (P < .001). The oral analgesic intake was less in the SBB and ISB groups than in the controls (P = .004). Although ISB remains the gold standard, SBB provides effective, safe, and easily administered postoperative analgesia in patients with an intact rotator cuff undergoing arthroscopic subacromial decompression.

Randomized Controlled TrialExtracorporeal shock wave therapy for calcifying tendinitis of the shoulder.
We prospectively studied extracorporeal shock wave therapy (ESWT) for calcific tendinitis of the shoulder in 46 consecutive patients. All patients were randomly divided into 2 groups: treatment and control. The 33 patients in the treatment group received 2 courses of ESWT at the energy density of 0.55 mJ/mm(2) (1000 impulses). ⋯ In contrast, elimination was partial in 2 control patients (15.3%) and unchanged in 11 (84.7%). There was no significant difference between Gärtner type I and type II groups in the Constant score (P > .05). ESWT shows promise for pain relief and functional restoration of calcific tendinitis with negligible complications.
