Purpose: The purpose of this study was to compare a control group and an experimental group, consisting of arthroscopic shoulder surgery patients who had received acute rehabilitation treatment and who were to perform scapular stabilization exercise. Methods: Sixteen subjects were studied. The control group, n=8, received instruction for basic physical therapy intervention. An experimental group, n=8, received instruction for doing scapular stabilization exercise (protraction, retraction, elevation, depression) 10 times, 6 times per week. To evaluate the effects of exercise, subjects were evaluated using a joint position sense of shoulder (JPS), disability of the arm, shoulder index (DASH), shoulder pain and disability index (SPADI). Results: Participants showed after the intervention, both groups saw their JPS errors at $30^{\circ}$, $60^{\circ}$, and $90^{\circ}$ significantly decrease relative to before the intervention (p<0.05). Both groups saw their JPS rates at $90^{\circ}$ significantly decrease (p<0.05), with no significant changes in JPS at $30^{\circ}$ and $60^{\circ}$ (p>0.05). SPADI and DASH significantly decrease after the intervention (p<0.05), with no significant decreases before the intervention (p>0.05). The change rates of SPADI and DASH significantly reduced (p<0.05). Conclusion: Low-intensity scapular stabilization exercise is considered effective as a clinical treatment for arthroscopic shoulder surgery patients who receive acute rehabilitation treatment.

Purpose : Purpose of this study was to investigate whether cervicothoracic posture was associated with scapula orientation and muscle activity during shoulder abduction. Methods : Cervicothoracic junction angle and thoracic kyphosis angle were measured in health twenty subjects. Then, scapular resting orientation and range of motion (upward/downward rotation, internal/external rotation) and muscle activity (upper trapezius, lower trapezius, serratus anterior) was determined using motion capture system and surface electromyography while subjects performed shoulder abduction. Results : Cervicothoracic junction angle was significantly associated with range of motion of scapular internal/external rotation during shoulder abduction. Thoracic kyphosis angle was significantly associated with scapular resting orientation of upward/downward rotation and average IEMG of lower trapezius. Conclusion : The result of this study shows that poor cervicothoracic posture is relationship with altered scapular kinematics cause of shoulder dysfunction. These findings suggested that cervicothoracic posture may be considered in occupation and exercise including arm elevation over head as well as used as predict factor to estimate shoulder dysfunction.

Iatrogenic damage of the rotator cuff followed by postoperative shoulder function loss is a potential complication after antegrade intramedullary nailing (AIN) for a humeral fracture. The authors present a case of arthroscopic rotator cuff repair and subacromial decompression of a non-healed rotator cuff tendon (mainly supraspinatus) and secondary impingement syndrome caused either by the tear or a proud nail after AIN for a mid-shaft humeral fracture. At presentation, the patient complained of right shoulder pain and 'snapping', especially during forward elevation and abduction of the shoulder, of 4 years duration. Right shoulder pain started sometime after pain due to the humeral shaft fracture, operation had subsided, and persisted after nail removal. Arthroscopic findings showed a longitudinal rotator cuff tear at the nail entry point that had not healed and severe fibrous hypertrophy on the acromion underspace, which is a unique finding since most longitudinal splits of tendon fibers are more likely to heal than conventional rotator cuff tears detached from bone. The torn rotator cuff was repaired after debridement and placing side-to-side sutures. At his 34-month follow-up after rotator cuff repair, the patient showed complete recovery and had excellent clinical scores.

Purpose: To evaluate the quantitative isometric muscle strength of shoulder girdle and the test reliability using by the equipment, named 'IsoTrack', selected by authors in the former studies. Methods: Thirty healthy subjects (9 men, 21 women) were recruited in two sessions, one for intratester and intertester reliability tests and the other quantitative isometric muscle strength tests. The neck flexion, extension and scapular elevation muscle strength was measured using a force measuring device as IsoTract. Results: Intraclass correlation coefficients for intratester reliability of the all subjects ranging between 0.96 and 0.97. For intertester reliability, the ICC and Pearson correlation correspond to 0.84 and 0.78. We gauged muscle strength of shoulder girdle muscles based on it and indicated quantified isometric muscle strength of women and men in left and right side. Conclusion: We concluded that there were high reiliability of isometric muscle strength of neck and shoulder girdle. Also, we gauged muscle strength of shoulder girdle muscles based on it and indicated quantified isometric muscle strength in left and right side in women and men. So this findings may assist in the measure of whole body muscle strength.

Objectives : This study was conducted to understand 4 groups in tentatively named "muscle coordinative manipulation" by Korean medicine. Methods : We researched some articles on meridian-muscle theory and muscle's action that are classified into 4 groups in muscle coordinative manipulation. Results : The outcome of examining the hypothesis is as follows: 1. The 1st hypothesis : 'Elevated shoulder' group mainly consists of muscles that are involved with shoulder elevation, abduction and external rotation. 'Lowered shoulder' group is mainly composed of muscles that acts of shoulder depression, adduction and internal rotation. 'Elevated pelvis' & 'Lowered pelvis' groups didn't show significant features by the movement of the hips. 2. The 2nd hypothesis : Most of muscles in 'elevated & lowered shoulder' groups are classified into 'hand taiyang' meridian-muscle. Most of muscles in 'elevated pelvis' group are included in 'foot jueyin' meridian-muscle. Most of muscles in 'lowered pelvis' group are classified into 'foot taiyang & foot yangming' meridian-muscle. Conclusions : There is no significant classification in muscles that comprise 4 groups in muscle coordinative manipulation when it comes to meridian-muscle theory and muscle function. More studies on chain reaction of muscle and subsequent analysis in Korean medicine are needed.

Purpose : The aim of this study is the assessment of the clinical outcomes after percutanous pinning of unstable two-parts fracture of surgical neck in humerus. Materials and Methods: This study was based on thirteen cases of non-comminuted unstable surgical neck fracture of humerus among 19 cases, which followed-up more than one year. Follow-up averaged 29 months. We treated with percutaneous pinning techniques and assessed clinical outcomes. Functional evaluation was performed using the standard method of research committee of American Shoulder and Elbow Surgeons(ASES). Results: Last follow-up ROM of shoulder joint were 142 degrees of forward elevation, 57 degrees of external rotation, 72 degrees of external rotation in 90 degrees abduction, and T8 of internal rotation. Pain scale was l(range : 0∼3). ASES scores was 86.2(range : 63.3~98.3). Patient satisfaction based on ASES were excellent in 6 cases, good in 5 cases, fair in 1 case, poor in 1 case. A case of fair result was caused by limitation of motion in shoulder joint and poor case was paraplegia patient after traffic accident. Conclusion : Percutaneous pinning is recommended for non-comminuted unstable fracture of surgical neck in humerus.

Irreparable rotator cuffs with retracted torn ends remain a significant challenge for most shoulder surgeons. Since repairs are preferable to reconstruction or replacement whenever possible, studies for anatomical reductions with minimal tension and secure fixation are important. In this study, the authors introduce an arthroscopic supraspinatus advancement (ASSA) procedure for retracted rotator cuff tears that could not be adequately reduced to the original footprint. Using modified long, narrow, curved Cobb elevators, procedures can be performed through lateral portals without any additional skin incision. Following meticulous stepwise three-compartment elevation procedures based on the supraspinatus insertion anatomy, the supraspinatus muscle could be safely elevated from the fossa and sufficiently advanced laterally. The authors suggest that ASSA could be a useful procedure for management of challenging retracted rotator cuff tears by maximizing lateral excursions that could convert irreparable tears to reparable tears in select patients.

The results of the operative treatment of the Grade III acromioclavicular joint injury is defined by the durability of the reduced joint and free of exertional pain. Several surgical techniques have been applied to reduce and stabilize the joints effectively. Resection of clavicular lateral end and subacromial decompression also could be applied to prevent post-operative arthritic change. Biomechanical studies reveals the role of clavicular elevation and rotation to achieve more than 90 degrees of elevation. It also serves as a attachment site of deltoid and trapezius muscle. The stability and mobility of the both acromioclavicular and coracoclavicular joint are important to get full functional recovery. We modified the methods of coracoacromial ligament transfer described by Weaver-Dunn and by Shoji et a!. to pre­vent pullout of the transferred ligament and to get more improved functional results. Main technical point was harvesting full thickness bone block and fix it through the key-hole to reduce pull out angle.
