Purpose: To investigate the effectiveness of injection therapy in the treatment of subacromial bursitis. Materials and Methods: A total of 38 patients with sonographic confirmation of subacromial bursitis were recruited into this study. The shoulder abduction range of motion and visual analog scale (VAS) were compared before injections and 3 wks after the completion of injections. Results: The shoulder range of abduction before injection was $77.89{\pm}14.17$ degrees and improved to $148.68{\pm}13.39$ degrees 3 wks after the injection treatments (P<0.05). VAS before injection was $6.8{\pm}1.4$ and improved to $1.4{\pm}0.8$ 3 wks after the injection treatments (P<0.05). Conclusions: Ultrasound may be used as an adjuvant tool in guiding the needle accurately into the inflamed subacromial bursa. The ultrasound-guided injection technique can result in significant improvement in shoulder abduction range of motion in treating patients with subacromial bursitis.

Purpose: We retrospectively studied the outcomes of the shoulder impingement syndrome for the treatment of the ultrasound-guided subacromial bursal steroid injection. Materials and Methods: Sixty-six shoulders of sixty-two patients with shoulder impingement syndrome treated from March, 2006 to April, 2009 were involved in this study. All cases underwent standardized, nonoperative treatment protocol consisting of 5~12 MHz high resolution ultrasound-guided local steroid injection into the subacromial bursa in modified Crass position. The shoulder range of motion, VAS score and impingement signs were evaluated during the initial and 1year visits. After injection, shoulder elevation exercise was encouraged. Statistical analysis with ANOVA model and Tukey's post-hoc test with the significance level at 5% were performed using SAS program. Results: All cases showed improved range of motion without limitation of shoulder function at immediate post-injection, 6-week, 3-month and 1year visits. The average VAS score at one year follow-up decreased to 2.85 from 6.47 before injection. In all cases the impingement signs became negative immediate after injection. However, 6 cases showed positive impingement signs after 6-week, which became negative after reinjection. The range of motion and VAS score were improved at one-year follow-up compared to initial visit (p<0.0001). No complication was noted at all follow-up period. Conclusion: Ultrasound-guided subacromial steroid injection alleviated the need of surgery, because it was successful in all our cases to improve pain and function of the shoulders until one year follow-up period.

석회화 건염은 회전근 개중 극상근 건에 석회가 침착되는 질환으로서 진행 양상에 따라 Formative, Resting, Resorptive phases로 나눈다. 치료는 물리 치료, Puncture, 국소 steroid 주사, 체외 충격파 등 보존적 치료에 반응을 잘 하며, 특히 resorptive phases때의 극심한 통증은 석회 침착 부위에 puncture나 needling lavege를 실시하면 즉각적인 동통 감소 효과와 함께 석회 침착의 자연 소실을 기대할 수 있다. 이러한 보존적 치료에 효과가 없을 경우 수술적 처치를 고려할 수 있는데 최근에는 대부분 관절경을 이용한 석회 제거술을 시행한다. 수술전 견관절 충돌 징후가 있거나 수술 소견상 이를 의심할 만한 소견이 있을 경우 견봉하 성형술을 함께 실시하기도 한다.

Purpose: The purpose of the study was to evaluate the accuracy and clinical outcome of ultrasound-guided glenohumeral joint steroid injection on adhesive capsulitis. Materials and Methods: Patients who were diagnosed as adhesive capsulitis by MRI and physical examination and did not improve their symptom with physical therapy and NSAIDS treatment more than 6 months were included in the study. Patients who showed any other shoulder pathology or history if trauma were excluded from the study. 33 patients including 15 males and 18 females were enrolled in the study, the average age being 55.1 (age 42~72). Cocktail of steroid, lidocaine, saline and contrast medium injected inside shoulder glenohumeral joint using novel approach (which we called acromioclavicular approach) under ultrasound guidance. Clinical outcome was measured through passive range of motion and VAS scoring system. Results: Based on radiographic findings, cases were classified according to the leakage of contrast medium; perfect confinement of contrast-medium inside the capsule, partial leakage of the medium and contrast-medium found at outside the joint. Total 25 cases (76%) out of 33 cases showed perfect confinement of contrast-medium inside the glenohumeral joint. Partial leakage was observed in 6 cases (18%), and contrast medium was observed outside of the glenohumeral joint in 2 cases (6%). Perfect-confinement group showed $111^{\circ}$($80{\sim}140^{\circ}$) of forward flexion and $48^{\circ}$($0{\sim}90^{\circ}$) of external rotation before injection, and improved to $134^{\circ}$($90{\sim}150^{\circ}$) of forward flexion and $70^{\circ}$($30{\sim}90^{\circ}$) of external rotation after injection (p<0.01). Partial leakage showed $120^{\circ}$($90{\sim}150^{\circ}$) of forward flexion and $70^{\circ}$($10{\sim}90^{\circ}$) of external rotation before injection, and improved to $139^{\circ}$($135{\sim}140^{\circ}$) of forward flexion and $78^{\circ}$($50{\sim}90^{\circ}$) of external rotation after injection (p<0.01). VAS score improved from 7.1 (score 3~9) to 2.6 (score 0~5) (p<0.01) in perfect confinement group, from 7.5 (score 7~9) to 3.3 (score 2~4) (p<0.01) in partial leakage group. Two group showed no significant difference. Conclusion: Accuracy of Acromioclavicular approach was 94% which is better than any other methods published so far. Partial leakage of the injection material did not show inferior result compared to perfect injection.

From May 1994 to May 1995, we performed a prospective controlled double-blind clinical study of 85 patients(85 shoulders). For inclusion in the study all patients met the following criteria: 1) a diagnosis of impingement syndrome by lidocaine injection test; 2) symptoms for at least three months; 3) no previous subacromial injection; 4) no evidence of rotator cuff tear. We excluded the patients from the study who showed a instability or other clear primary cause. The patients were randomized to receive either 5/subcc/ 2% lidocaine with 4ee of 20mg/cc Depomedrol(Group 1) in 45 cases or 5/subcc/ 2% lidocaine solely(Group 2) in 40 cases. At three month follow-up, all results were better in steroid group than control group. But at one year, improvement of pain and daily activity showed no difference between two groups. So we conclude that the use of subacromial steroid injection is effective for short-term therapy in the treatment of subacromial impingement syndrome, but the long-term effectiveness is doubtful.

Purpose: We evaluated calcium resolution and clinical improvement of calcific tendinitis after conservative and arthroscopic treatment. Materials and Methods: We reviewed 126 patients of calcific tendinitis treated from January, 2002 to April, 2005. Average age was 53 and female dominant in 77% of the cases. Calcium deposits were involved in supraspinatus tendon in 84% of the cases. We compared clinical changes for 64 cases treated with injection, and 12 cases treated by arthroscopic decompression with 6 month follow-up. Results: 77%(49/64) of the cases with steroid injection showed symptom improvement. Even though complete resolution of calcific deposit occurred in 36%(23/64), incomplete resolution in 17%(11/64) and no change in 47%(30/64), Pain was relieved in 87%(20/23), 82%(9/11) and 67%(20/30), respectively. With arthroscopic treatment, calcium deposit completely resolved in 83%(10/12), and all cases showed pain free motion after 6 months. Conclusion: Conservative treatment with steroid injection was effective for acute pain in resorptive phase. In cases of arthroscopic treatment, there was no need for complete removal of calcium deposit during the procedure, but clinical symptoms improved with resolution of the deposit.

Purpose: The purpose of this study is to report the preliminarily result of the radiologic disappearance of the calcific material, regardless of the size, type or location, on one-time ultrasonographic (US) assisted needling for calcific tendinitis of the shoulder. Materials and Methods: From March to August 2011, 46 patients (47 shoulders) with symptomatic calcific tendinitis were treated by one-time US assisted needling. Initially, a diagnostic US was performed with patient to determine the locations, numbers and sizes of calcific deposits. After 1% lidocaine local anesthesia, the calcific material was punctured with an 18-gauge needle under US monitoring. If no calcific material was aspirated after 2 or 3 additional attempts, the deposits was performed multiple puncture to achieve decompression. And then all patients were performed subacromial corticosteroid injection. All patients were followed up 4 weeks after procedure. To assess the radiologic disappearance after one-time US assisted needling, simple radiographs of the treated shoulder were performed and size, dense, and morphology of the calcific deposits were compared with those in baseline radiographs. For clinical evaluations, visual analogue scale for pain and function (PVAS and FVAS), and American Shoulder and Elbow Surgeons (ASES) score were assessed. Results: There were 11 male and 35 female patients with the mean age of 53.8 years (28-71). The morphology of the calcific deposits were 31 type A and 16 type B by French Arthroscopic Society classification and mean size was $2.9{\pm}6.7$ mm before the procedure. At 4 weeks after the index procedure, the radiographic unchanged group was included in 10 cases and changed group was 37 cases. No intergroup difference for the clinical results after the procedure was evident, but group FAS classification before the procedure was significantly different (p=0.011). Conclusion: At 4 weeks after one-time US assisted needling for calcific tendinitis of the shoulder, the radiographic size- or dense-changed cases were showed in 79%, regardless of the size, type or location of the calcific material. But the radiographic nearly or complete disappearance were showed in only 21%.

Purpose: We compared with USG-guided steroid injection group and blind steroid injection group for the treatment of calcific tendinitis to evaluate the effectiveness of the treatment modalities. Materials and Methods: We reviewed two groups of calcific tendinitis treated with steroid injection and follow up upto 6 month after injection. Group I was blind injection for 88 patient with average age of 53years old and female gender in 77%. Group II was USG- guided injection for 102 patients with average age of 54years old and female gender in 85%. We compared follow up results according to age, gender, size of tendon involvement, initial VAS score, and phase of the calcific tendinitis between two groups. Results: At 6 month's follow up period, USG-guided injected group was more prevalent compared to blind injection group with 92%(94/102) and 72%(64/88) (P<0.05). In Group I, 77%(49/64) patients have improved symptom. And in Group II, 92%(86/94) patients have improved symptom in formative or resorptive phase. Despite of symptom improvement, calcium deposit is remained 47%(30/64) in Group I, and 20%(19/94) in Group II. Conclusion: Conservative treatment of Shoulder calcific tendinitis patients through USG-guided injection is more effective than Blind injection in pain relief & calcium decrease. The patients USG-guided injected group was more prevalent in follow up at outpatient clinic, throughout more accurate injection with improved confidence.
