Hereditary multiple exostosis (HME) is an autosomal dominant disorder manifested by the presence of multiple osteochondromas. Although the lesions are benign in nature, exostoses are often associated with characteristic progressive skeletal deformity and displaying clinical symptoms such as mechanical irritation or impingement. We present the successful arthroscopic resection in a 24-year-old HME male with impingement syndrome and long head tendon tear of the biceps caused by osteochondroma arising from the distal clavicle.

In fencing, athletes must hit opponents by the sword of fencing, so they need long reach between their foot and their tip of the sword. We thought the motion of shoulder joint, mainly scapula, is one of the important roles in this action and noticed the difference of right and left side in muscles around scapula caused by this action. We evaluated these muscles with MRI imaging in 5 high-level athletes of fencing who aims at the next Olympics (3 men and 2 women, their average age is 21 years). Besides we observed their physical measurement related with these muscles. We reported the characteristics of these results.

The Superior Shoulder Suspensory complex (SSSC) maintains a normal stable relationship between the upper extremity and the axial skeleton. Traumatic double disruptions of the SSSC frequently create an unstable anatomic situation and is difficult-to-treat. When this double disruption is managed conservatively, significant displacement can occur at either or both sites and result in long-term problems and functional disabilities. Therefore surgical management is generally necessary. The authors experienced two cases of double disruptions of the SSSC treated with arthroscopic surgery & and reported good results.

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 following will describe a method of evaluating the SLAP lesion in the recurrent anterior dislocation of the shoulder. We have named it the biceps load test. The biceps load test is performed with the patient in the supine position and the arm to be examined is abducted 90/sup°/, and the forearm is in the supinated position. First, the anterior apprehension test is performed. When the patient become apprehensive, the patient is allowed active flexion of the elbow, while the examiner resists elbow flexion. If the apprehension is relieved or diminished, the test is negative. If aggravated or unchanged, the test is positive. A prospective study was performed, in which 75 patients who were diagnosed as having recurrent unilateral anterior instability of the shoulder underwent the biceps load test and arthroscopic examination. The biceps load test showed negative results in 64 of these patients, of which the superior labral-biceps complex was intact'in 63 cases and only I shoulder revealed a type n SLAP lesion. E]even patients with a positive test were confirmed to have type n SLAP lesions. A positive biceps load test represents an unstable SLAP lesion in a patient with recurrent anterior dislocation of the shoulder. The biceps load test is a reliable test for evaluating the SLAP lesion in the recurrent anterior dislocation of the shoulder(sensitivity: ,9] .7%, specificity: 100%, positive predictive value: 1.00 and negative predictive value: 0.98). Biceps contraction increases the torsional rigidity ?of the glenohumeral joint and long head of biceps tendan act as internal rotator of the shoulder in the abducted and externally rotated position. These stabilize the shoulder in abduction and external rotation position in the biceps load test.

Purpose: to apply lymph massage to the patients that contracted lymphedema after mastectomy to resolve blood congestion, stimulate circulation, and control swelling long-term. Methods: The subjects include 20 female patients that were diagnosed with breast cancer histologically and contracted lymphedema within one to two years after mastectomy. They received lymph massage from March to August, 2008. Using a measuring tape(capable of measuring mm), the arm circumference was measured in both the sick and normal arm. Only the data from the sick arm were compared before and after the treatment. The measuring points were five; the back of the hand(a certain distance[about 10cm] was set between the end of the middle finger to the center of the palm), the wrist(the smallest section), the lower arm(at a certain distance[about 10cm] from the internal bending part of the elbow), the elbow(the bending part), and the upper arm(at a certain distance[about 10cm] from the internal bending part of the elbow). Collected data were analyzed using the SPSS/WINDOWS Version 12.0 program. Results: There was a reduction of lymphedema observed in all the points including 10cm in the upper arm, the elbow, 10cm in the lower arm, the wrist and the back of the hand after lymph massage, and the reduction had statistically significant differences(p<.05). Conclusion: Those results indicate that lymph massage has effects on the reduction of lymphedema in the early patients that contracted it after mastectomy.

The purpose of this study was to kinematically analyze the differences between short(2.17 m) and long(10.94 m) putting stroke motions. Thirteen male professional golfers were participated in this study. Experiment was conducted on the artificial grass mat in the gymnasium. Kinematic data were collected by the 60 Hz Kwon3D motion analysis system. Differences were compared by SPSS paired t-test and one-way ANOVA. Duncan was used for post-hoc test and a=.05. The results were as follows: 1. Ground projected trajectory of the putter head were statistically straight during both short and long putts. 2. There was no consistent alignment tendency among shoulder, hip, and stance alignments. However stance alignment was consistent between short and long putts. Thus it is assumed that professional golfers align their body based on their stance alignment. 3. During putting, shoulder rotated not only up and down but also right and left. 4. Left and right elbow distance was maintained during all phases of the putts for both short and long putts. 5. Inter foot distance of long putting was longer than that of short putting.

Background: For anatomic total arthroscopic repair, cementless humeral fixation has recently gained popularity. However, few studies have compared clinical, radiographic, and patient-reported outcomes between cemented and press-fit humeral fixation, and none have performed follow-up for longer than 5 years. In this study, we compared long-term postoperative outcomes in patients receiving a cemented versus press-fit humeral stem anatomic arthroscopic repair. Methods: This study retrospectively analyzed 169 shoulders that required primary anatomic total shoulder arthroplasty (aTSA). Shoulders were stratified by humeral stem fixation technique: cementation or press-fit. Data were collected pre- and postoperatively. Primary outcome measures included range of motion, patient reported outcomes, and radiographic measures. Results: One hundred thirty-eight cemented humeral stems and 31 press-fit stems were included. Significant improvements in range of motion were seen in all aTSA patients with no significant differences between final cemented and press-fit stems (forward elevation: P=0.12, external rotation: P=0.60, and internal rotation: P=0.77). Patient reported outcome metrics also exhibited sustained improvement through final follow-up. However, at final follow-up, the press-fit stem cohort had significantly better overall scores when compared to the cemented cohort (visual analog score: P=0.04, American Shoulder and Elbow Surgeon Score: P<0.01, Simple Shoulder Test score: P=0.03). Humeral radiolucency was noted in two cemented implants and one press-fit implant. No significant differences in implant survival were observed between the two cohorts (P=0.75). Conclusions: In this series, we found that irrespective of humeral fixation technique, aTSA significantly improves shoulder function. However, within this cohort, press-fit stems provided significantly better outcomes than cemented stems in terms of patient reported outcome scores. Level of evidence: III.

Purpose : To describe long-term clinical results and serial changes in the postoperative range of motion(ROM) after arthroscopic treatment for a limitation of motion(LOM) of the elbow. Materials and Methods : The subjects who visited chosun university hospital from December, 1996 to January 2000 were twenty-one patients ranging from 37 to 54 years of age, and the average age was 43.2 years. The chief complaints were painful limitation of motion of the elbow and average ROM showed that flexion contracture were 17 degrees and further flexion were 87 degrees. Results : The total ROM was $70^{\circ}$ preoperatively. 2 months after postoperatively the mean flexion contracute improved from $17^{\circ}\;to\;3^{\circ}$ with further flexion from $87^{\circ}\;to\;122^{\circ}$ degrees. One year after postoperatively the mean flexion contracture were $5^{\circ}$ and further flexion were $113^{\circ}$. All patients reported a decresement in pain level as well as improvement in motion. There was no complication in this series. Conclusion : Arthroscopic surgery appear to be satisfactory management modality for degenerative elbow contractures.

Complete denervation after severe brachial plexus injury make significant muscle atrophy with loss of proper function. It is much helpful to reconstruct the essential function of the elbow flexion movement in patient with total loss of elbow flexion motion after brachial plexus lesion which was not recovered with nerve surgery or long term conservative treatment from onset. In whole arm type brachial plexus injury, if there were no response to neurotization or neglected from injury, the volume of the denervated muscle is significantely reduced month by month. About 18 months most of the muscle fibers change to fibrous tissues and markedly atrophied irreversibly, further waiting is no more meaningful from that period. Authors performed 14 cases of functioning gracilis muscle transfer from 1981 to 1995 with microneurovascular technique, neuromusculocutaneous free flaps were performed for reconstruction of lost elbow flexion function. Average follow-up period was 5 years and 6 months. We used couple of intercostal nerves as a recipient nerve which were anastomosed to muscular nerve from obturator nerve in all cases. Recipient vessels were three deep brachial artery and eleven brachial artery which were anastomosed to medial femoral circumflex artery with end to end or end to side fashion. Average resting length of the transplanted gracilis were 24 cm. We can get average 54 degree flexion range of elbow with fair muscle power from flail elbow. There were one case of muscle necrosis with lately developed thrombosis of microvascular anastomosed site which comes from insufficient recipient arterial condition, 3 cases of partial marginal necrosis of distal skin of the transplanted part which were not significant problem with spontaneously solved with time goes by gracilis muscle has constant neurovascular pattern with relatively easy harvesting donor with minimal donor morbidity. Especially it has similar length and shape with biceps brachii muscle of upper arm and longer nerve pedicle which can neurorrhaphy with intercostal nerve without nerve graft if sufficient mobilization of the nerves from both sides of gracilis and intercostal region. Authors can propose gracilis muscle transplantation with intercostal nerves neurotization is helpful method with minimal donor morbidity for neglected brachial plexus palsy patients.
