Purpose : The purpose of this study was to compare the muscle activities of infraspinatus, serratus anterior, upper trapezius, and triceps brachii in different supporting surface intervals during push-up exercise. Method : Subjects of the study were 18 healthy male students without any orthopedic or neurological injuries including neck and shoulder surgeries and can perform a push-up exercise required for the study. EMG was used to measure the muscle activities of four muscles. Result : There were statistically significant differences of all the muscles in three different supporting surface intervals(p<0.5). Muscle activity of upper trapezius was the highest(MVIC 39.40%) in the narrowest width and the lowest in the widest width. In infraspinatus, muscle activity was the highest(MVIC 36.23%) in the narrowest width and the lowest in the widest width. In serratus, muscle activity is the highest(MVIC 58.04%) in the widest width and the lowest in the narrowest width. In triceps brachii, muscle activity is the highest(MVIC 68.51%) in the widest width and the lowest in the narrowest width. Conclusion : Muscle activities are at the highest with the narrowest width in the upper trapezius and the infraspinatus. In the serratus and triceps brachii, however, muscle activities are at the highest with widest width.

Objective : SLAP is rupture of biceps brachii muscle tendon and it's origin, posterior side of superior labral to anterior glenoid fossa. Snapping and Pain, instability are its typical symptoms. SLAP is physical damage so surgeons use arthroscopy. In point of surgeons view, a conservative medicine is not effective for lesion of labrum. So In this article, we report a result of conservative treatment for the amatuer baseball player diagnosis with type 2 superior labral anterior posterior lesion. Methods : In this case, patient played amatuer baseball for 2 years, had diagnosis with type 2 Superior labral anterior posterior lesion by MRI after right shoulder Injury. OS recommened arthroscopy surgery. But he receive conservative Korean medicin treatment in Korean medicine hospital, including Atx, BV, herbal acupunture and rehabilitation excersise. Results : After 6 months, in the end of continuous conservative treatment and rehabilitation excersise, patient can play baseball normally, and felt a little pain. But In physical examination, he still has a some abnormal signs. Conclusion : A Conservative treatment for an amatuer baseball player diagnosis with SLAP type 2 was effective in restore of fuctional activities, but usefulness of this treatment needs more study.

A 25-year-old woman presented to the emergency room with a painful and swollen right forearm. She had just sustained an injury from an accident during which her arm was tightly wound by a rope as she was lowering a net from a fishing boat. Before being released, her arm was rigidly trapped in the rope for approximately ten minutes. Radiographs revealed anterior dislocation of the radial head that was accompanied by plastic deformation of the proximal ulna, manifested as a reversal of the proximal dorsal angulation of the ulna (PUDA); suggested a Monteggia equivalent fracture. With the patient under general anesthesia, we reduced the radial head by posterior compression at $90^{\circ}$ of elbow flexion and at neutral rotation of the forearm. However, the reduction was easily lost and the elbow re-dislocated with even slight supination or extension of the arm. After the osteotomy of the ulnar deformity to restore the PUDA to normal, the reduction remained stable even with manipulation of the arm. We found that the patient could exercise a full range of motion without pain at the 3-month follow-up, and neither residual instability nor degenerative changes were observed at the final 3-year follow-up.

Background: Individuals with scapular winging may have proprioceptive dysfunction which is important for motor control and causes shoulder instability. Reduced serratus anterior (SA) and lower trapezius (LT) muscle activity accompanied by over-active upper trapezius (UT), and pectoralis major (PM) may be contributing factors. Flexi-bar (FB) exercise may be used to increase joint position sense (JPS) and alter the target muscle activities. Objects: This study aimed to investigate the immediate effects of flexi-bar exercise prior to knee push-up plus (FPK) versus knee push-up plus (KPP) on JPS and muscle activity of SA, LT, UT, and PM in subjects with scapular winging. Methods: Eighteen subjects with scapular winging were recruited. JPS was investigated at baseline, after KPP and after FPK. Passive and active JPS errors were calculated by isokinetic equipment. Surface electromyography was used to record muscle activities during KPP and FPK. One-way repeated-measures analysis of variance and post hoc analyses were used to analyze the JPS error measured at baseline, after KPP and after FPK. Paired t-tests were used to compare muscle activities between KPP and FPK. Results: Passive JPS error was significantly decreased after KPP (p = 0.005) and after FPK (p = 0.003) compared to the baseline. Active JPS error was also significantly decreased after KPP (p = 0.016) and after FPK (p = 0.012) compared to the baseline. There was no significant difference in the passive and active JPS errors between KPP and FPK. SA activity during FPK was significantly increased (p = 0.024), and LT activity during FPK was significantly increased (p = 0.006). There were no significant differences in the UT and PM activity. Conclusion: FB might be recommended to immediately improve passive and active JPS and to selectively increase SA and LT muscle activities during KPP in individuals with scapular winging.

Purpose: The purpose of this study is to investigate the accompanying lesions of humerus greater tuberosity fracture with anterior shoulder dislocation and to analyze its clinical results. Materials and Methods: From May 2005 to November 2008, arthroscopy was performed on a total of 30 selected patients who were diagnosed with humerus greater tuberosity fracture with anterior shoulder dislocation and who were also under the age of 40. The preoperative and postoperative Constant and Rowe scores were compared. Results: There was a total of 21 cases of anteroinferior labral lesions: 2 Bankart lesions, 4 bony Bankart lesions, 4 Perthes lesions, 2 free ALPSA lesions, 3 GLAD lesions and 6 capsular tears. For other lesions, 5 rotator cuff partial tears, 3 SLAP lesions and 1 biceps tendon rupture were found. The constant scores were increased from 56.3 to 94.43 points (p=0.034), and the Rowe scores were increased from 52.56 to 91.76 points (p=0.026). Conclusion: For humerus greater tuberosity fracture with anterior shoulder dislocation, the accompanying lesion was identified and the fracture was treated using arthroscopy. Good clinical results and bone union were achieved. According to the secondary arthroscopic findings, all of the Perthes lesion, the free ALPSA lesion, the GLAD lesion and the capsular tear spontaneously healed or they did not progress to extended rupture although arthroscopic suture was not performed. Any postoperative secondary instability was not observed.

Purpose: To evaluate the short-term follow up outcome and the effectiveness of arthroscopic vertical shift of anteroinferior capsulolabral complex, plication of AIGHLC (anterior band of inferior glenohumeral ligament complex) and thermal capulorraphy, posteroinferior suture plication, rotator interval closure as an adjuncts in recurrent instability of megafrequency with night time dislocation. Materials & Methods: From March 1998 to February 2004, we have had 18 shoulders out of 156. All of the cases have been night time dislocation above more one time. The age were average 29.4$(21{\sim}37)$ year old. The average follow up were 21.1 $(12{\sim}45)$months We checked Rowe score and ROM at pre-operation, post-operation 6 months,1 year & last follow up period. Results: Above good results were 16 cases(88.9%). The excellent were 6 cases, good were 10, fair 1, poor 1. Conclusions: In recurrent anterior shoulder dislocation in greater than 50 frequency, arthroscopic stabilization can be an alternative technique for selected patients against open inferior capsular shift. But more long ter n follow up and large materials will be needed in the future study.

The rotator cuff is situated in a potential tight subacromial space and undergoes senescent structural changes commonly observed in other joints of the body. When the cuff fails, spontaneous healing of the torn tendon is not expected to occur, and multiple factors may be responsible. Its fibers are under tension and typically retract on tearing. The subacromial bursal inflammation and alterations in normal glenohumeral kinematics have been considered in the development of symptoms. Controversy continues to exist concerning the pathogenesis of rotator cuff disease. The heterogeneity of the disorder, as well as the notion that rotator cuff disease may not actually represent a continuum of the same process, but rather, is a compilation of independent disorders, may partly explain the differing viewpoints on its origin. Two contrasting pathogenetic mechanisms have been extensively described and include vascular, or intrinsic, causes and impingement, or extrinsic, factors. Other etiologies have also been reported that include trauma, congenital or developmental factors, and instability. For successful treatment of the rotator cuff diseases, it is essential to understand the structure and function of rotator cuff and to clarify the pathogenesis and natural history of its disorder.

Purpose: In this prospective, randomized study, we compared the results of early motion versus conventional immobilization after the arthroscopic Bankart repair. Materilal and Methods : We performed an arthroscopic Bankart repair using suture anchors in 62 patients with traumatic anterior shoulder instability and randomized them into two groups; Group 1 (n=28; mean age, 28 years) underwent three-week of immobilization and conventional rehabilitation program, while Group 2 (n=34; mean age, 29 years) underwent an accelerated rehabilitation program with staged range of motion and strengthening exercises starting from the immediate postoperative day. Selected patients were non-athletes with a classic Bankart lesion and a robust labrum. Analysis of outcome included pain scores (6-week and follow-up: 31(9 months), range of motion, return to activity, recurrence, patients’ satisfaction with each program, and shoulder scores (ASES, UCLA, and Rowe). Results : The recurrent rate was not different between the two groups (2 anterior apprehension from each group) (p=0.842). Patients with accelerated rehabilitation resumed functional range-of-motion faster and returned earlier to the functional level of activity (p<0.05). Accelerated rehabilitation decreased postoperative pain and more patients were satisfied with this program (p<0.05). No differences were found between the two groups at the follow-up with regards to the shoulder scores, return to activity, pain score, and the range-of-motion. Conclusions : Early mobilization after arthroscopic Bankart repair does not increase the recurrence rate in selected patients. Although the final outcomes are similar in both groups, the accelerated rehabilitation program promotes functional recovery and reduces postoperative pain, which enables patients an early institution of desired activities.

We evaluated biceps pulley as a stabilizing sling for the long head of biceps tendon in the rotator interval. We present 3 cases of detached biceps pulley which impinges on posterosuperior glenoid labrum in the position of late cocking. Pulley impingement related to anterior shoulder instability was relieved after Bankart repair. In another two cases, impingement symptoms were disappeared after resection of the detached biceps pulley.
