US-guided percutaneous treatment facilitated prompt shoulder function recovery and pain relief. Treated patients had better outcomes than did nontreated patients at 1 year. However, 5 and 10 years after the procedure, the nontreated group reported outcomes similar to those of the treated group.

BackgroundOpen hip surgery is known to be a risk for heterotopic ossification (HO), and nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely recognized as an effective prevention. Hip arthroscopy is gaining popularity thanks to the possibility of treating femoroacetabular impingement (FAI) with a minimally invasive technique, however little is known about its rate of postoperative HO. The aim of the present study is to evaluate HO prevalence after hip arthroscopy for FAI and its relationship with NSAID prophylaxis.Materials and methodsWe retrospectively reviewed 300 FAI cases who have been managed with hip arthroscopy in two different hospitals from April 2006 to May 2009. All medical records and indications at discharge were analyzed, focusing on administration of NSAIDs, as well as follow-up roentgenograms with regard to presence of HO around the hip joint. The patients were divided into two groups: a treatment group of 285 hips which received NSAID prophylaxis and a control group of 15 hips which did not.ResultsFive hips presented HO, with overall prevalence of 1.6%. All five patients with HO belonged to the control group. No HO was observed in the treatment group. Thus, HO rate turned out to be significantly higher (P < 0.001) in patients who did not receive NSAIDs after surgery.ConclusionArthroscopic treatment of FAI is not exempt from potential development of HO. NSAIDs after arthroscopic FAI treatment seem to be an effective prevention.

Purpose:To determine whether saline temperature infl uences procedure performance and outcome in patients undergoing ultrasonography (US)-guided lavage for the treatment of rotator cuff calcifi c tendinitis (RCCT). Materials and Methods:This study was approved by the institutional review board, and informed consent was obtained from all patients. , and analysis of variance tests. Results:Procedure duration was signifi cantly shorter ( P , .001) in patients treated with warm saline (mean, 576 seconds 6 121) than in those treated with room-temperature saline (mean, 777 seconds 6 151). Calcium dissolution was signifi cantly easier in patients treated with warm saline (median score, 1) than in those treated with roomtemperature saline (median score, 2). Subgroup analysis according to calcifi cation appearance at US showed a signifi cant difference between groups for both soft ( P = .003) and hard ( P , .001) calcifi cations. No overall signifi cant differences were found for VAS score (warm saline group: baseline = 8.9 6 0.6, 1 month = 4.7 6 0.6, 2 months = 4.0 6 0.7, 3 months = 3.4 6 0.4, 1 year = 3.0 6 0.7; roomtemperature saline group: baseline = 9.2 6 0.4, 1 month = 4.5 6 0.7, 2 months = 4.1 6 0.9, 3 months = 3.1 6 0.7, 1 year = 3.2 6 0.8; P = .491). Postprocedural bursitis was observed in eight patients in the warm saline group and 20 in the room-temperature saline group ( P , .022). Conclusion:In the treatment of RCCT, warm saline appears to reduce procedure duration and improve calcifi cation dissolution while reducing the frequency of postprocedural bursitis.q RSNA, 2011
