Purpose: Rotator cuff tears involving the subscapularis are less common than those involving the superior and posterior rotator cuff. The purpose of the present study was to report the clinical results of repair of isolated traumatic tears of the subscapularis tendon. Materials and Methods: Fifteen patients (13 males, 2 females; mean age 46.2 years; range 35 to 52) with unilateral ruptures of the subscapularis tendon after trauma who underwent arthroscopic repair between February 2003 and October 2008 were reviewed retrospectively. All the cases were isolated tears of the subscapularis without the involvement of any other rotator cuff tendon and were followed for at least two years (mean 28 months). The entire subscapularis was involved in 9 cases and the tear was localized to the upper two thirds in 6 cases. The preoperative and postoperative status of patients with isolated subscapularis tears were analyzed using the Constant Score, American Shoulder and Elbow Society Index (ASES Index) and postoperative integrity was determined through magnetic resonance imaging. Results: The average clinical outcome scores and strength were all improved significantly at the time of the final follow-up. The constant shoulder score improved from 41.5 to 81.3 points (P<0.05) compared to before surgery and ASES index improved from 46.4 to 89.6 points (P<0.05) postoperatively. Thirteen patients (87%) were satisfied with the result of the treatment. The total tears were significantly more improved by surgery than the partial tears. In 12 of 15 patients (80%) were judged to reveal healed tendon on magnetic resonance imaging at a mean of 13 months postoperatively. The postoperative score was significantly lower for the patients with a failed repair than it was for those with an intact repair (P<0.05). Conclusion: Repair of traumatic isolated subscapularis tears through arthroscopic techniques effectively restores patient function with regard to pain, mobility, strength and postoperative tendon integrity. The postoperative integrity of the repair correlates with the functional results and the total tears were more improved by surgery than the partial tears, but future studies may be needed.

Arthroscopic single-row rotator cuff repair is a well established surgical technique for the treatment of rotator cuff tears. However, the problem of postoperative retear remains a concern. Various avenues are being explored to address this problem. Some studies have suggested that restoring the anatomical footprint may improve the healing and initial strength of the repaired rotator cuff tendon. The double-row technique was introduced as a method of reconstructing the anatomical footprint. According to biomechanical studies on cadavers, this technique improved mechanical strength and reduced gap formation. However, the biological properties of reattached tendon such as tension, and vascularity have not been proved yet. Furthermore, the apparent mechanical superiority of the double-row over the single-row construction has not resulted in better functional outcomes. Therefore, the less complicated and less costly single-row technique is still the recommended treatment for rotator cuff repairs.

배경 및 목적 : 한국 구개열환자에게는 된소리 자음(농음0의 구음산출의 난도가 높다는 것은 임상적으로 잘 알려져 있다. 그러므로 본 연구에서는 한국 구개열 환자에게 있어서 난도가 높은 농음의 산출 메커니즘의 기본적 요소를 규명하므로서 언어치료의 새로운 방법모색에 기여하고져 하였다. 연구방법; 비강자음에 후속된 3종의 어두 파열자음 산출시의 구개범거근의 근활동 양상의 차이를 비교검토하므로서 농음의 산출특성을 검색하고져 하였다. 관찰기록 방법은 근전도는 유구침금전극(hooked wire electrodes)을 구강내로부터 경점막적으로 유도하였다. 연구결과 : 격음과 농음의 파열자음에서 평음보다 높은 구개범거근의 근활동이 관찰되었으나 격음과 농음 사이에선 유의미적인 차이는 보이지 않았다. 결 론 : 금후의 과제로는 피험자를 늘려 재확인을 하는 일, 및 농음과 격음의 변별요소에 관해 더욱 검토할 필요가 있는 것이 시사되었다.

Purpose: To compare the clinical and radiological result of arthroscopic Mattress Locking suture repair to that of a Simple suture repair with small and medium-sized rotator cuff tears. Materials and Methods: Among 92 patients who were followed up after arthroscopic repair in patients with small and medium-sized rotator cuff tear from April 2007 to October 2010, 27 patients who took Arthroscopic Mattress Locking suture were set as group I and 65 patients who took Simple suture were set as Group II. The average age of patients were 58 years old and average follow-up period was 30 months. For analysis, VAS, ASES and KSS were used to analyze the range of joint movement and pain. And, for the image result, MRI performed after operation were evaluated. Results: The average VAS, KSS, UCLA score and ASES prior to surgery improved in the last follow-up (p<0.001), while was no difference in two groups (p>0.001). In MRI follow-up examination, the 2 cases (7.41%) of group 1 showed increased rupture lesions with improved symptoms. And the 12 cases (18.47%) of group 2 showed increased rupture lesions with improved symptoms. Retears in the group I were significant less than the group II (p<0.001). Conclusion: Comparing patients with small and medium-sized rotator cuff tear who took arthroscopic mattress locking suture repair to those who took simple suture repair after over one year follow up period, the clinical result showed no significant difference between two groups. However, Mattress Locking suture repair showed excellent radiological result compared to simple suture repair when comparing rerupture.

Purpose: The purpose of this study was to evaluate the pain recovery pattern according to the integrity and to analyze the factors affecting the progress and level of pain postoperatively. Materials and Methods: We examined 153 patients, who were treated with arthroscopic rotator cuff repair. 101 rotator cuff tears were full-thickness tear and 52 were partial tear. The mean follow up duration was 20 months (12~30 months). We evaluated the visual analogue scale, range of motion, ASES (American Shoulder and Elbow Surgeons), and UCLA (University of California at Los Angeles) scores preoperatively and postoperatively. We analyzed the pain recovery pattern between partial and full thickness tear using Student T-test and the factors affecting the progress and level of postoperative pain using multiple regression analysis. Results: The change patterns of visual analogue scale after arthroscpoic repair were similar regardless of the tear integrity. The VAS showed a continuous decreasing pattern, but increased at first 3 weeks postoperatively and at 7 weeks postoperatively, and then, decreased thereafter. The average VAS was ${\leqq}2$ points by postoperative 3 months. The factor affecting the pain score at 3 months was related to the preoperative limitation in forward flexion ($r^2=0.377$, p=0.021). Conclusion: There was no differences of the pain recovery pattern according to the integrity, and the factor affecting the progress of postoperative pain was preoperative angle of forward elevation. So, the appropriate preoperative rehabilitation protocol that can improve motions of the shoulder joint would help to improve the level of postoperative pain and functional recovery.

기관을 침범한 갑상선 악성종양을 제거한 후에 성문하부에 비교적 큰 기관 결손이 발생할 수 있다. 단단문합술은 넓은 부위의 결손부를 재건하는 방법으로 널리 받아들여지고 있지만, 문합부 파열, 반회후두신경마비, 재협착 등의 합병증이 발생할 수 있다. 본 증례는 기도를 침범한 갑상선 유두암종을 제거한 후 윤상연골과 기관연골의 비교적 큰 결손부를 흉쇄유돌근 근골막피판을 사용하여 안전하게 재건한 사례이다. 55세 남자 환자가 기도를 침범한 갑상선 유두상암으로 내원하였으며 기도침범은 윤상연골(둘레의 약 30%)과 4개의 기관연골(둘레의 약 50%)을 해당하는 넓은 부위였다. 수술 전 기관절개술을 시행하여 주위 기관연골의 상태가 좋지 않아 단단문합술 시행 후 문합부 파열 가능성이 있다고 판단하여 흉쇄유돌근 근골막피판을 이용하여 재건하기로 계획하였다. 갑상선 절제술, 경부림프절 절제술, 흉쇄유돌근 근골막피판을 이용한 재건술을 시행하였으며 수술 후 12일째 별다른 문제없이 퇴원하였다. 환자는 수술 후 현재 22개월 간 기도 협착 등의 별다른 합병증 없이 지내고 있다. 흉쇄유돌근 근골막피판은 성문하부나 기관지 전외측벽의 비교적 큰 결손부를 재건하는 데 유용하게 사용될 수 있다.

Purpose: To evaluate efficacy of ultrasound guided prolotherapy in patients with persistant symptoms after rotator cuff repair. Materials and Methods: Between January and December of 2008, 90 patients who had persistant pain and shoulder adhesion 4 weeks after rotator cuff repair were treated with ultrasound guided prolotherapy. The mean age was 55.2 years. Visual analogue scale (VAS) and range of motion (ROM) before and after the procedure, complications related to the procedure were analyzed. Results: The average VAS score at 4 weeks follow up decreased to $2.5{\pm}2.304$ from $6.3{\pm}1.25$ before prolotherapy and forward flexion range at 4 weeks follow up increased to $143{\pm}26.63$ from $106{\pm}21.64.$ Four weeks after the ultrasound guided prolotherapy, 74 cases(82%) reported of improved pain and ROM, 13 cases(14%) reported of improvement after 2~5 days of the procedure and 3 cases(4%) had no improved in pain and ROM. No complications were encountered. Conclusion: The authors believe that ultrasound guided prolotherapy in repaired rotator cuff tear patients theoretically increased possibilities of healing and with relieving the pain of the patients results in increased possibility of rehabilitation effect.
