Purpose: To identify associated findings in glenohumeral joint in rotator cuff tear and evaluate its clinical significance, we examined minor and major changes during arthroscopic or mini open repair. Materials & Methods: We reviewed 66 patients of rotator cuff tear treated from March, 2001 to January, 2004. Of 38 cases of small to medium tear, average age was 53 years old and involved in dominant arm in 27 cases. Of 28 cases of large to massive tear, average age was 58 years old and involved in dominant arm in 26 cases. Minor and major associated changes of the glenohumeral joint were evaluated in the tendon of biceps long head, biceps pulley, cartilage of the glenoid and humeral head, labrum and synovium. Results: Minor changes in biceps tendon were in 35% of cases, biceps pulley in 18%, cartilage of humeral head in 27%, cartilage of glenoid in 18%, labrum in 38%, and synovium in 42%. Major changes in biceps tendon were in 6% of cases, biceps pulley in 35%, arthritis of humeral head in 3%, arthritis of glenoid in 2%, labrum in 6%, and synovium in 21 %. Major changes in biceps tendon were 5% in Group I and 7% in Group Ⅱ(p>0.05) and in biceps pulley, 18% and 57% in each (P<0.05). Minor changes of arthritis were prevalent in glenoid cartilage and major changes were more prevalent in humeral head. There were no differences in minor changes of labrum and synovium, but major changes were more prevalent in Group Ⅱ. Conclusion: The prevalence of intraarticular associated changes of rotator cuff tear were 63% in synovium, 54% in labrum, 53% in biceps pulley, 41% in biceps tendon, 30% in humeral head and 20% in glenoid cartilage in order. Major changes of biceps pulley, humeral head, labrum and synovium were more prevalent in Group Ⅱ.

Purpose: To evaluate pathologic patterns and outcomes of treatment of a biceps tendon lesion associated with a rotator cuff tear. Materials and Methods: We reviewed 92 patients (i) who underwent surgery for a cuff tear, (ii) for whom the biceps lesion could be observed retrospectively, and (iii) had a minimum follow-up of 2 years. The pathology of biceps tendon was classified into 4 types: tenosynovitis, fraying or hypertrophy, tear, and instability. All but the 4 with massive cuff tears were repaired. The biceps lesions were treated with debridement in 30, tenotomy in 10, tenodesis in 8, and recentering in 4. UCLA scoring was used for clinical results. Results: Seventy patients had a biceps lesion, 19 tenosynovitis, 22 fraying or hypertrophy, 21 a tear, and 8 instability. A biceps lesion was observed in 63% of cases of cuff tears below the medium size, and in 88% of cases with cuff tears above the large size. UCLA scores according to the pathology of the biceps lesion were 29.6 in the absence of a biceps lesion, and 28.3 in its presence. UCLA scores in patients with tenotomy or tenodesis for associated biceps tendon lesions were 28.2. Conclusion: There is a greater incidence and severity of a biceps lesion with a larger cuff tear. Therefore, the cause of a biceps lesion might be related to the cause of the cuff tear. Among the several options of treatment for biceps lesion, tenotomy or tenodesis may be particularly effective in providing pain relief.

Background: The study of conservative and surgical treatment of distal biceps tendinopathy and associated biceps tendon partial rupture. Methods: Twenty-one cases with distal biceps tendonitis and partial ruptures were studied who visited Pohang Semyeong Christianity Hospital from June 2010 to August 2017. The mean age was 57.1 years (39-69 years), 14 males and 7 females. The mean duration of symptom at the time of first visit was 4.9 months (0.2-14 months). Ultrasonography and magnetic resonance imaging were performed for patients with severe symptoms. According to the severity of the symptoms, splint immobilization, oral nonsteroidal anti-inflammatory drugs, and ultrasound-guided steroid injection were performed. Surgical treatment was performed if the patient did not respond to conservative treatment for 3 to 6 months or longer. Results: There were 9 cases of partial rupture of the distal biceps tendon associated with distal biceps tendinopathy on imaging studies. Conservative treatment showed symptomatic improvement in 16 of 21 cases. In 4 cases with a relatively mild symptom, anti-inflammatory analgesics and intermittent splinting showed good result. In 12 cases, symptoms improved after ultrasonography-guided steroid injection. Surgical treatment was performed on 5 cases that did not respond to conservative treatment. Conclusions: Conservative treatment of distal biceps tendinopathy may promise good results. However, in case of partial tear of the distal biceps tendon and refractory to conservative treatment, surgical treatment may be needed.

Purpose: To evaluate follow-up after the clinical results of arthroscopic assisted tenodesis of the proximal biceps tendon using an interference screw. Materials and Methods: We reviewed 30 cases of patients receiving tenodesis of the proximal biceps tendon between January, 2008 and January, 2010 who treated with arthroscope. The results were judged by VAS, ASES, tenderness in the biceps groove, fixation failure and the degree of deformity. Results: VAS, ASES scores increased by a statistically significant during the final observation in all patients than before surgery (p<0.05). For those with rotator cuff tear had low ASES results (p<0.05), respectively. But, tenderness in the biceps groove was 17% (5 cases), pepeye deformity and incresead BAD (biceps apex distance) were 10% (3 cases). Conclusion: Arthroscopic tenodesis of the proximal biceps tendon using an interference screw to patients with proximal lesion in their biceps tendon, can achieve good results, but it is possible to groove tenderness and popeye deformity.

Synovial chondromatosis is an uncommon condition, and the involvement of the shoulder joint is rare. A 15 year old female patient presented to author's institution for right shoulder pain. We checked the plain radiographs and MRI. And they showed that a diagnosis of synovial chondromatosis in the shoulder, and they also demonstrated that the disease involved the bicipital tendon sheath as well as glenohumeral joint. We removed all loose bodies with total synovectomy by arthroscopic procedure, and a mini-open procedure for the lesions of biceps tendon sheath. Arthroscopic treatment affords excellent visualization of the shoulder joint with less morbidity. However, with current arthroscopic techniques, it is difficult to manage the synovial chondromatosis of biceps tendon in bicipital groove. The authors suggest that the complete elimination of synovial chondromatosis involving shoulder requires a mini-open procedure for the lesions of biceps tendon sheath in addition to the arthroscopic resection of the affected synovium and loose body removal in the glenohumeral joint.

Background: Sonoelastography (SE) is a new technique that can assess differences in tissue stiffness, the purpose of this study was to evaluate the ability of SE to assess the long head of biceps tendon alteration. Methods: Forty shoulders of 36 consecutively registered patients with clinical symptoms and conventional ultrasonography findings of biceps tendinitis or tendinosis, and 40 asymptomatic shoulders of 20 healthy volunteers were assessed with SE. Transverse and longitudinal images of long head of biceps tendon were obtained using SE. SE images were performed by one orthopedic surgeon and evaluated by two orthopedic surgeons using an experimentally proven color grading system. Results: The transverse images of SE showed a sensitivity of 87.5%, a specificity of 95.0% and a accuracy of 91.3%, the longitudinal images of SE showed a sensitivity of 92.5%, a specificity of 90.0% and a accuracy of 91.3%. Inter-observer reliability of SE was in 'almost perfect agreement' with a weighted kappa coefficient of 0.83. Conclusions: SE is valuable in the detection of the intratendinous and peritendinous alterations of biceps tendon, and has excellent accuracy and excellent correlation with conventional ultrasound findings.

Background: Distal biceps rupture is a relatively uncommon injury that can significantly affect quality of life. Early complications following biceps tendon repair are not well described in the literature. This study utilizes a national surgical database to determine the incidence of and predictors for short-term complications following distal biceps tendon repair. Methods: The American College of Surgeons' National Surgical Quality Improvement Program database was used to identify patients undergoing distal biceps repair between January 1, 2011, and December 31, 2017. Patient demographic variables of sex, age, body mass index, American Society of Anesthesiologists class, functional status, and several comorbidities were collected for each patient, along with 30-day postoperative complications. Binary logistic regression was used to calculate risk ratios for these complications using patient predictor variables. Results: Early postoperative surgical complications (0.5%)-which were mostly infections (0.4%)-and medical complications (0.3%) were rare. A readmission risk factor was diabetes (risk ratio [RR], 4.238; 95% confidence interval [CI], 1.180-15.218). Non-home discharge risk factors were smoking (RR, 3.006; 95% CI, 1.123-8.044) and ≥60 years of age (RR, 4.150; 95% CI, 1.611-10.686). Maleness was protective for medical complications (RR, 0.024; 95% CI, 0.005-0.126). Surgical complication risk factors were obese class II (RR, 4.120; 95% CI, 1.123-15.120), chronic obstructive pulmonary disease (COPD; RR, 21.981; 95% CI, 3.719-129.924), and inpatient surgery (RR, 8.606; 95% CI, 2.266-32.689). Conclusions: Complication rates after distal biceps repair are low. Various patient demographics, medical comorbidities, and surgical factors were all predictive of short-term complications.

Background: Popeye deformity is common after rupture of the biceps muscle's long head tendon. Herein, we report on histological changes in biceps brachii muscles following tenotomy of the long head biceps tendon. Methods: Twelve Sprague-Dawley rats (12-week-old) underwent tenotomy of the long head biceps tendon in the right shoulder. At postoperative weeks 4, 7, and 10, the operative shoulders were removed by detaching the biceps brachii muscle from the glenoid scapula and humerus; the opposite shoulders were removed as controls. H&E staining was performed to elucidate histological changes in myocytes. Oil-red O staining was performed to determine fatty infiltration. Myostatin antibody immunohistochemistry staining was performed as myostatin is expressed by skeletal muscle cells during myogenesis. Results: H&E staining results revealed no changes in muscle cell nuclei. There were no adipocytes detected. Compared with that of the control biceps, the cross-sectional area of the long head biceps was significantly smaller (p=0.00). Statistical changes in the total extent of the 100 muscle cells were significant (p=0.00). Oil-red O staining revealed no fatty infiltration. Myostatin antibody immunohistochemical staining revealed no significant difference between the two sides. Conclusions: Muscular changes after tenotomy of the long head biceps included a decrease in the size of the individual muscle cells and in relative muscle mass. There were no changes observed in muscle cell nuclei and no fatty infiltration. Moreover, there were no changes detected by myostatin antibody immunohistochemistry assay.

Lesion of the superior glenoid labrum and the insertion of the biceps tendon are a common cause for shoulder pain in patients performing overhead sports. Medial shearing stress during overhead throwing may cause biceps instability and associated rotator cuff problem aggravates the symptoms. Careful attention to the history and physical examination and may arouse suspicion of injury to the biceps tendon and the superior labral complex. Progress in shoulder arthroscopy has led to the identification of the lesion and normal variation. Treatment should be directed according to the type of lesion and related symptoms.

A ganglion is a benign cystic mass, commonly found around a joint or tendon sheath. It frequently occurs at the wrist, foot, ankle, and knee. Intratendinous ganglion has been rarely reported, and intratendinous ganglion of the long head of biceps brachii is extremely rare. According to our literature review, this is the third case of intratendinous ganglion of the long head of biceps brachii, and the first case of arthroscopic treatment. Therefore we report a case of an arthroscopic treatement for an intratendinous ganglion of the long head of biceps brachii.
