Rupture of the pectoralis major muscle may occur in youngers or athletes associated with extreme sports, especially during the weight training. It is uncommon, but the incidence is increased by the recent growth of athletic population, According to the drift, variable methods of operative treatment for the functional and cosmetic recovery are introduced. We report a case of pectoralis major muscle rupture which was successfully repaired using transosseous repair and suture anchors five months after the initial injury during the bench-pressing.

Purpose: We wanted to evalulate the clinical results of pectoris major tendon transfer for a neglected winged scapula that was caused by paralysis of the serratus anterior due to injury to the long thoracic nerve. Materials and Methods: A patient had neglected winged scapula that followed an arthroscopic operation for multi-directional instability of the shoulder joint, which was caused by traumatic dislocation. The patient was treated with pectoralis major tendon transfer using the modified Eden-Lange procedure. The range of a motion was improved from forward flexion $90^{\circ}$ and external rotation $70^{\circ}$ to $170^{\circ}$ and $150^{\circ}$ respectively. Results and Conclusion: There were no complications or recurrence and the patient's psychological satisfaction was also high. If the shoulder girdle muscles are intact, except for the serratus anterior, then pectoralis tendon transfer is a satisfactory method that can provide normal scapulo-thoracic motion.

Purpose: Poland syndrome is rare disease which is characterized by absence of unilateral pertoralis major muscle accompanied by ipsilateral syndactyly or brachydactyly, which was described first by Alfred Poland in 1841. Materials and Methods: We performed the physical examination, laboratory test and radiologic evaluation to 18 year old male, who complaint asymmetry of right anterior chest. Results: We diagnosed the Poland syndrome due to absence of right pectoralis major muscle and brachydactyly of right hand. Conclusion: Current authors report a patient who had hypopalsia of pectoralis muscles, which needed differential diagnosis with pectoralis major rupture.

본 연구에서는 배낭 어깨끈의 압박에 의한 통증과 신경 및 혈관압박을 감소시키기 위해 배낭 어깨끈의 압박부위 개선방안을 제안하고 이 배낭이 두가지 국부적 discomfort를 감소시키는 효과를 실험을 통해 평가하였다. 어깨끈 변형을 통해 등세모근 윗쪽부위 및 대흉근 바깥쪽부위의 압박을 대흉근 안쪽부위, 등세모근 중간부위 및 견갑골부위로 이동시키고 어깨끈과 등세모근 윗쪽부위는 접촉하지 않도록 하는 방안이 제안되었다. 실험결과 압박에 의한 통증과 신경 및 혈관압박의 정도가 어깨끈의 압박부위가 개선된 배낭에서 기존배낭보다 상대적으로 적은 것으로 평가되었으며 총체적인 선호도도 어깨끈의 압박부위가 개선된 배낭이 더 높았다. 보조적으로 배낭 착용시의 생리학적 부하정도를 측정한 결과, 개선된 배낭이 생리학적 부하를 효과적으로 감소시키지는 못하는 것으로 나타났으나 주관적 안락도 평가에서는 오히려 우수하였다. 이상이 결과는 본 연구에서 제안한 압박부위 개선배낭이 배낭 착용시의 안락도 결정에 있어 상대적으로 중요도가 높은 국부적 discomfort측면에서 기존배낭보다 우수하여, 생리학적 부하 측면에서는 개서효과가 없음에도 불구하고 전체적 안락도의 향상에 성공한 것으로 분석된다.

Purpose: The purpose of this study is to evaluate the clinical results of arthroscopic biceps long head suprapectoral tenodesis using an interference screw. Materials and Methods: We reviewed the cases of 30 patients who underwent arthroscopic biceps long head suprapectoral tenodesis using an interference screw between January 2008 and January 2010. The minimum follow up period was one year. Twenty patients had rotator cuff tears. The results were analyzed by VAS, ASES, tenderness in the bicipital groove, fixation failure, and the degree of deformity. Results: VAS, ASES scores showed a statistically significant increase during the final observation in all patients, compared with those before surgery. However, five patients (17%) had anterior shoulder pain and tenderness in the biceps groove, and three patients (10%) had Popeye deformity. Better results were achieved in patients without rotator cuff tear than in patients with rotator cuff tear (p<0.05). Conclusion: Arthroscopic biceps long head tenodesis above the pectoralis major using an interference screw in patients with a pathologic lesion of the proximal biceps tendon showed good results at the last follow up. However, further study for tenderness in the biceps groove in 17% of patients is needed.

Purpose: Irreparable massive rotator cuff tears pose a distinct clinical challenge for the orthopaedist and non-surgical treatment has had inconsistent results and proven unsuccessful for chronic symptoms, while surgery, including debridement and partial and complete repairs have had varying degrees of success. Materials and Methods: For rotator cuff tears that are deemed irreparable, treatment options are limited. Results and Conclusion: The use of tendon transfers (latissimus dorsi for posterosuperior type cuff defects and pectoralis major for subscapularis defects) in younger patients to reconstruct rotator cuffs and re-establish function and restore shoulder kinematics can be useful in solving this difficult problem.

The purpose of this study was to obtain data to support applied motions of bench press and to provide basic data for the efficient execution of the exercise by analyzing muscular activation through measuring electromyogram of pectoralis major and erector spinae when flat bench pressing with feet on the ground versus feet on the bench. For this study, 4 amateur bodybuilders and 2 health trainers were chosen as subjects. Surface electrodes were attached on the measuring muscles; pectoralis major and erector spinae. Motion phases were defined for the flat bench press and each subject, with a 10RM load, performed a set with feet on the ground and another set with feet on the bench. Data was analyzed in SPSS 20.0 and the following results were obtained. The placement of the feet did not affect the muscular activation of the pectoralis major during the flat bench press. however, the muscular activation of the erector spinae was different between the two positions.
