Materials and methods
This study was approved by the Institutional Review Board. All patients who had a history and physical exam findings consistent with the diagnosis of impingement syndrome, were recruited into the study. Inclusion criteria included: (1) a history of shoulder pain predominantly along the lateral aspect of the acromion near the insertion of the deltoid, especially with overhead activities; (2) symptoms that persisted for at least 2 months; (3) a positive impingement sign; (4) no major weakness of
Results
Sixty shoulders in 58 patients (age 30-85 years old, 28 males and 30 females) were enrolled in the study from July 2003 to April 2005. There was no difference among the 3 groups when stratified to gender, age, or BMI (Table I). Forty-two patients (42 shoulders) completed the 3-month follow-up examination in the office, while 16 (18 shoulders) completed the 3-month evaluation via telephone. Detailed telephone interviews to assess function, range of motion, and patient satisfaction were noted in
Discussion
Numerous meta-analyses have been published with mixed results regarding the efficacy of corticosteroid injections into the subacromial space for the impingement syndrome.4, 11, 12, 18, 25 Several prospective, randomized trials have been performed, specifically comparing corticosteroids against placebo. Blair et al6 compared corticosteroid with local anesthetic to local anesthetic alone and reported superior results in pain relief and shoulder range of motion with the addition of

2018, Egyptian RheumatologistCitation Excerpt :Group I: 20 patients treated through the GH joint (posterior) approach; the joint space was located by ultrasound guidance. The needle was introduced 1 cm below and lateral to the spine process and advanced into the GH joint space; directed horizontal and little lateral [15]. Group II: 20 patients treated through SASD (lateral) approach, the subacromial space was located ultrasound guided, the needle was introduced 1 cm below the acromion angle and advanced SASD [15].

2016, Best Practice and Research: Clinical RheumatologyCitation Excerpt :Rutten et al. reported that both methods were 100% accurate [26], and Dogu et al. found that accurate injections were performed in 65% in the USGI group and 70% in the LMGI group [27]. Four clinical studies have investigated the accuracy of LMGIs into the subacromial space [28–31]. One used MR arthrography and the others used fluoroscopy plus contrast media for verification.
