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.

Reports of osteomyelitis in the proximal humerus with pyogenic glenohumeral arthritis of adjacent joints mostly involve pediatric patients. Nowadays, osteomyelitis that is secondary to adjacent pyogenic glenohumeral arthritis is extremely rare, even more so in adults than in pediatrics. We report a rare case of the pyogenic glenohumeral arthritis followed by osteomyelitis of the proximal humerus in an elderly patient. Initially, we diagnosed a case of pyogenic glenohumeral arthritis only, which, despite arthroscopic synovectomy, did not resolve and severe pain continued. Subsequent radiological imaging, performed after our suspicion of a secondary involvement, allowed us to diagnose osteomyelitis combined with the pyogenic glenohumeral arthritis, which we had overlooked because of the extreme rarity of the condition in adults since the antibiotic era began.

The muscle strengths in various postures are used in our daily life with or without our recognition. Also, many works are still performed with strengths, although mechanization and automation have been fairly accomplished at the industry site. Since the late seventies, various body measurements have been conducted periodically in Korea, however, muscle strengths have not been measured actively. For this reason, the muscle strength data have been hardly accumulated. The aims of this study are to learn more about the physical strength of young-aged Koreans and to provide basic information for designing equipments, tools and facilities in the work site and daily life. The muscle strengths that are related to shoulder and upper limbs joints, which are used frequently, are measured in this study. Eighteen muscle strengths, from seven different movements such as elbow flexion, elbow extension, shoulder abduction(seated), shoulder adduction(seated), shoulder rotation(internal and external), lifting a tray, and turning a key(inward and outward) were measured. For every movement, the muscle strengths for both hands were measured. In each measurement, five seconds averaged value and peak value were collected. Comparing the average value, the strength of shoulder adduction was the strongest for male and female, while strength of turning a key inward with left hand was the weakest for male and female. Strengths of preferred hand in elbow extension, shoulder abduction, shoulder external rotation, lifting a tray, and turning a key were stronger than those of non-preferred hand for both male and female. Rohrer's index considerably had an effect on muscle strength. The results of this study can provide some basic information not only in designing the equipment and facilities in work site or daily life, but also in selection, training and management of workers.

Lateral epicondylitis, also known as 'tennis elbow', is a degenerative rather than inflammatory tendinopathy, causing chronic recalcitrant pain in elbow joints. Although most patients with lateral epicondylitis resolve spontaneously or with standard conservative management, few refractory lateral epicondylitis are candidates for alternative non-operative and operative modalities. Other than standard conservative treatments including rest, analgesics, non-steroidal anti-inflammatory medications, orthosis and physical therapies, nonoperative treatments encompass interventional therapies include different types of injections, such as corticosteroid, lidocaine, autologous blood, platelet-rich plasma, and botulinum toxin, which are available for both short-term and long-term outcomes in pain resolution and functional improvement. In addition, newly emerging biologic enhancement products such as bone marrow aspirate concentrate and autologous tenocyte injectates are also under clinical use and investigations. Despite all non-operative therapeutic trials, persistent debilitating pain in patients with lateral epicondylitis for more than 6 months are candidates for surgical treatment, which include open, percutaneous, and arthroscopic approaches. This review addresses the current updates on emerging non-operative injection therapies as well as arthroscopic intervention in lateral epicondylitis.

Purpose: Stability of joints and maintenance of range of motion are needed for optimum function. The most common complaint about the elbow joint is joint stiffness. Recent articles have reported good outcomes in the treatment of stiff elbow joints. However, deciding which procedure to use is always difficult. Materials and Methods: Morrey et al. reported that the functional range of motion of the elbow joint is $30-130^{\circ}$ of flexion-extension and $50^{\circ}C$ of supination and pronation. About 90% of daily activities are done using this range of motion. Stiff elbow joints can be classified according to the traumatic events that caused the problem or the location of the main pathology. Intraarticular pathology includes severe articular mismatch, intraarticular adhesions, loss of articular cartilage, mechanical blockade by osteophytes, loose bodies, and hypertrophied synovium. Extraarticular pathology includes severe capsular adhesion due to the trauma or to dislocation, contracture of the collateral ligaments or muscles, bony bridge. Results and Conclusions: The main pathology underlying the loss of extension is the fibrous contracture of the anterior capsule. In this pathology, an anterior capsulectomy would be helpful. The main pathology underlying the loss of flexion is the contracture of the posterior band of medial collateral ligament.

Differences between left and right-side joint range of motion may affect canine locomotive ability and movement. Passive range of motion (PROM) joint measurement provides the limits that a particular joint can move in its physiological planes of motion without influence of muscle activity. To compare left and right-side flexion and extension of the glenohumeral, humeroulnar/humeroradial, coxofemoral and femorotibial joints and for laterality PROM differences. Siberian Husky dogs were selected (n = 18), mixed gender, aged (1.4-11.8) years living and working together. Goniometry measured joint PROM, a validated, non-invasive method. Dogs were conscious and placed in standing position. Triplicate measures of joint flexion and extension were taken bilaterally of each dog for afore-mentioned joints. Median values of triplicate measures were computed. Paired t-tests compared laterality of joint PROM, gender, age (< 6 vs. ≥ 6 years) effects. Inferential symmetry indices [SI] were calculated. For all joints, there was no significant difference (p > 0.05) between left and right-side flexion and extension measures nor between genders. Age (< 6 vs. ≥ 6 years) had a significant effect on right hip flexion (p < 0.001); both left and right-side shoulder flexion (p < 0.001); elbow flexion (p = 0.001 and p < 0.001); hip extension (p = 0.02 and p < 0.001) respectively. The shoulder joint showed greatest PROM asymmetry (SI = 3.63%). Bilateral PROM measures are important to consider in joint movement and assessment. These results warrant further investigation with larger cohorts of defined age groups.

Purpose: We report case of neglected elbow dislocation for three years. Material and method: A 45 years old female patient presented with neglected elbow dislocation for three years. Since the patient had contracture in both lateral and medial collateral ligament of elbow, dissection was done. After total separation of posterior articular capsule and incision of anterior articular capsule, by manual manipulation, reduction of radiohumeral and ulnohumeral joints were obtained. We applied modified Morrey type hinged external fixation in the elbow and done early elbow exercise. Result and Conclusion: Since we have experienced a satisfactory result in the case with neglected elbow dislocation for 3 years by using open reduction and hinged external fixation, we report it with the literature.

Purpose: The purpose of this study is to evaluate the relationship between trochlear medial facet osteophyte (TMFO) and elbow flexion in the elbow joints without trauma history. Materials and Methods: Twenty five patients, who underwent computed tomography without elbow trauma history, were reviewed. Patients were checked for osteophyte or loose bodies in the coronoid and olecranon sides. The height and length of TMFO were measured. Results: The average elbow flexion contracture was $18.6^{\circ}$, and further flexion was $112.1^{\circ}$. The TMFO height and length was 2.2 mm and 4.7 mm, respectively. The average elbow further flexion was $105.1^{\circ}$ in the coronoid block group (n=14) and $119.1^{\circ}$ (p=0.011) in the coronoid free group (n=11). The relationship between further elbow flexion and TMFO was significant with a partial correlation coefficient of 0.687(p<0.000) in the TMFO length. Conclusion: Elbow joints with longer TMFO length decrease further flexion.

Despite its importance for the understanding of joint kinematics in vivo, there has been few studies about shoulder joints. The purpose of this study is to analyze the glenohumeral joint during internal and external rotation at 90 degrees of abduction using in vivo noninvasive motion analysis system. MRI was performed for the following seven positions from maximum internal rotation to maximum external rotation at intervals of 30 degrees. We used 3D-gradient echo sequencing (TR: 12 ms, TE: 5.8 ms, 0.8 mm-slice thickness). Our method is based on matching three-dimensional MR images by the similarity of the image intensity. We analyzed the in vivo three-dimensional motions of the glenohumeral and scapulothoracic joint during this motion. In scapla plane, the mean rotation angle of the glenohumeral join was 105.5 degrees ($SD{\pm}39.0^{\circ}$). The mean rotation angle of the scapulothracic joint was 27.5 degrees ($SD\;{\pm}\;7.7^{\circ}$). The contribution ratio is almost 3.8:1 of glenohumeral and scapulothracic joint respectively.
