We investigated the reliablity of the ultrasonography for diagnosis of rotatar cuff taers. We prepared histological sections of forty shoulder joints In match the ultrasound planes, and conducted a comparative study of tke two sets of images. hi cases of rotator cuff tear, hyperechogenic and cartilaginfication of the tear site were detected as hyperechogenic foci. On the countrary, the regions in which tendon fibers were decreased or absent showed sonolucent areas. We caluculated the echo level of rotator cuff objectively. The area of abnormal echo level and the other regions located in the same depth of the rotator cuff were defined by ultrasonic equipment. The mein difference in these two echo levels was calculated. The mean difference in patients with rotator cuff tears was larger than that in normal cases. These results indicate that ultrasonography is a useful procedure in many patients with rotator cuff lesions.

Enchondromas generally occur in the hand and uncommonly in the long bones. Because enchondromas are usually asymptomatic, most are discovered during diagnostic radiology for another disease. Here, we describe a case of enchondroma in the right humerus in a 79-year-old female patient with concomitant rotator cuff tear arthropathy. The patient was initially hospitalized for prolonged pain and pseudoparalysis of the right shoulder. The condition, which was histologically confirmed as an enchondroma in the proximal humerus, was treated with curettage and reverse total shoulder arthroplasty. In this case report, we present a rare case of an enchondroma with combined rotator cuff tear arthropathy.

Purpose: The purpose of this study was to evaluate the effects of muscle strengthening exercise on shoulder function and pain for rotator cuff tear patients. Method: The subjects of this study, partial tear of the rotator cuff diagnosed patients, twelve patients were picked up, who were agreed with this research. The twelve patients received muscle strengthening exercise for 4 weeks, which consisted of 5 times per week, 40 min of supervised exercise program. Shoulder function and pain, measured by ROM, CMS, SST, PPT and VAS. Result: In comparison of VAS, PPT and ROM, CMS, SST were showed a more improved after intervention. Conclusion: Therefore, muscle strengthening exercise is useful to improve the shoulder function and pain for rotator cuff tear patients.

Background: The Korean Shoulder Scoring System (KSS) is a reliable and valid procedure for discriminative assessment of the clinical status of patients with rotator cuff tears. This study evaluates the correlation between the preoperative KSS and factors in patients with rotator cuff tears. Methods: From November 2009 to June 2016, 970 patients who underwent arthroscopic rotator cuff repair were retrospectively evaluated. A total of 490 patients met the study criteria. Preoperative factors included age, sex, symptom duration, mediolateral (ML) and anteroposterior (AP) tear size, acromiohumeral distance (AHD), tangent sign, tendon involvement (type I, supraspinatus; type II, supraspinatus and subscapularis; type III, supraspinatus and infraspinatus; type IV, all 3 tendons), fatty infiltration of rotator cuff muscles (group I, Goutallier stages 0 and 1; group II, Goutallier stages 2, 3, and 4), and KSS. Results: Old age, ML tear size, and AP tear size negatively correlated with the preoperative KSS (p<0.001). AHD showed a positive correlation with the preoperative KSS (p<0.001). A significantly inferior preoperative KSS was found in females and type III tendon involvement (p<0.001). For supraspinatus and infraspinatus, the preoperative KSS of group II fatty infiltration showed a significantly lower score than group I fatty infiltration (p<0.05). Conclusions: A relatively lower preoperative KSS was associated with old age, large tear size, narrow AHD, female, type III tendon involvement, and group II fatty infiltration of the supraspinatus and infraspinatus. Our study indicates that preoperative KSS can be a good measurement for the preoperative status of patients with rotator cuff tears.

Background: The purposes of the study were to examine rotator cuff tendon degeneration with respect to harvesting location, to determine a rationale for debridement of the torn end, and thus, to determine adequate debridement extent. Methods: Twenty-four patients with a full-thickness rotator cuff tear were included in the study. Tendon specimens were harvested during arthroscopic rotator cuff repair from three locations; from torn ends after minimal regularization of fraying (native end group, NE group), from torn ends after complete freshening of the frayed end (freshened end group, FE group), and from the macroscopically intact portion just distal to the musculotendinous junction (musculotendinous junction group, MTJ group). Control samples were harvested from patients admitted for surgery for proximal humerus fracture. Harvested samples were evaluated using a semi-quantitative grading scale. Results: Mean total degeneration scores in the NE group ($13.3{\pm}3.21$), the FE group ($12.5{\pm}2.30$), and in the MTJ group ($10.8{\pm}3.10$) were significantly higher than those in the normal control group ($5.0{\pm}2.87$; all p<0.001). Mean total degeneration score in the NE group was significantly higher than that in the MTJ group (p=0.012), but was not from that of the FE group. Mean total degeneration score in the FE group was not significantly different from that of the MTJ group. Conclusions: Tendon degeneration exists throughout the entire tendon to the macroscopically intact portion of full-thickness rotator cuff tear. Therefore, aggressive debridement to grossly normal appearing, bleeding tendon is unnecessary for enhancing healing after repair.

Purpose: To evaluate the integrity of repair & technical tip in use of Massive Cuff Stitch at arthroscopic repair of rotator cuff tear. Materials and Methods: Twenthy-nine cases of arthroscopically repaired full thickness tear of rotator cuffs which are medium sized were evaluated. Between December 2004 to September 2005 we have studied, the average age 53($42{\sim}69$) years old, mean follow-up was 15($12{\sim}21$) months. We analyzed the results statistically by paired t-test. The integrity of repair were verified by follow up MRI which were checked 11 cases and ultrasound which were checked 10 cases. Results: VAS of pain improved preoperative average 7.1 to postoperative 0.9, ADL improved 11.2 to 25.6 respectively, UCLA improved 13.7 to 32.9(all, P<0.05). 89.7% showed excellent & good results at the final follow-up. The satisfied rate was 93.1%(27 cases). There was re-rupture of the repaired rotator cuff in one case out of 11 cases which were checked by MRI, and in one case out of 10 cases which were checked by ultrasound, and there was one case of thinning of cuff which were checked by ultrasound. Conclusion: The use of Massive Cuff Stitch in arthroscopic repair of rotator cuff tear have been reduced technical failure. It will be good surgical technique which maintain the integrity of repairs.

Objectives : The purpose of this study is to investigate the latest trend of studies on treatments of postoperative rotator cuff tear patients which are published in Korea. Methods : We investigated the studies on the treatments of postoperative rotator cuff tear patients via searching 6(six) Korean web databases(NSDL, RISS, Korean traditional knowledge portal, OASIS, KISTI, KCI). As a result, 16(sixteen) studies were found. We classified the papers by publication date, published journal, method of study, type of treatment, evaluation scale and referencing research ethics. Results : 16(sixteen) papers were published from 2006 to 2017. The papers were published in The journal of Korean shoulder & elbow society, The journal of korean acupuncture & moxibustion medicine, etc. 5(five) randomized controlled trials, 5(five) non-randomized controlled trials, 4(four) case reports and 2(two) Retrospective report have been found. For types of treatment, 6(six) exercise therapies, 3(three) Korean medicine treatments and 7(seven) other treatments have been found. Main evaluation tools were VAS, ROM, NRS and Muscle strength. Conclusions : In this study, we analyzed the latest trend of studies on treatments of postoperative rotator cuff tear patients. Reviewing the international trends of studies on treatments for postoperative rotator cuff tear are essential for the future studies.

회전근 개의 전층 파열은 운동, 고정, 약물 등의 치료로 재생되기 어렵다. 파열은 시간이 지나면서 격심한 통증은 없어질 수 있으나, 대부분의 환자에서 어깨나 머리 위로 다시 움직일 때 증상이 재발된다. 작은 파열은 진행할 수 있으며, 광범위한 파열 시 통증이 감소될 수 있으나 점진적인 근력 약화가 동반된다. 치료 받지 않은 회전근 개 파열 환자의 일부는 견관절 관절염이 속발될 수 있다. 보존적 방법으로 치료하여도 증상이 지속될 때, 증상을 호전 시키고 기능을 회복시키는 가장 좋은 방법은 수술적 봉합이다.
