PURPOSE: The evaluation and management of a completely transected tendon of the hand is relatively clear. In most cases, the integrity is assessed by physical examination(eg, broken normal cascade, motion loss) but occasionally, It happens in troubles. because of pain, limited patient cooperation(eg, child, unconscious patient), and other associated injuries(eg, fractures, foreign bodies). METHODS: From september 2006 to August 2007, 28 patients were evaluated with real time ultrasonography preoperatively and postoperatively. Twenty eight patients with injured tendon were evaluated using an HDI 5000 Sono CT(Philips Medical Systems, Bothell, WA) machine with a high resolution, 7.5MHz hockey stick linear probe. Dynamic evaluation was performed in real time. RESULTS: Surgery was performed after the ultrasonographic evaluation. Sonographic diagnosis and intraoperative findings were correlated. Ultrasonographic findings show tendon discontinuity, gaps, and fluid collection. CONCLUSION: We conclude that ultrasonography is helpful in evaluating and managing acute tendon injury. Especially, in cases of completely lacerated tendon, ultrasonography can identify the location of the proximal tendon stump and partial lacerated tendon, ultrasonographic diagnostic tool can decrease misdiagnosis.

Various methods have been described for surgical treatment of recurrent shoulder dislocation. Arthroscopic techniques for stabilizing the shoulder have the theoretical advantage of reduced complication, decreased discomfort, and improved motion. The arthroscopic Bankart procedure was performed in 23 cases at Department of Orthopaedic Surgery, Yonsei University College of Medicine, from January, 1991 to December, 1993. This study is an attempt to evaluate results of arthroscopic Bankart procedure by Caspari's technique. Results of this study were as follows: l. According to the clinical evaluation of Rowe, results were excellent in 18 cases, good in 2 cases, fair in 1 cases and poor in 2 case. The prognosis was related to the size of Hill-Sachs lesion. 2. Complication after treatment included 5 cases of knot problem, 1 case of subluxation, and 2 cases of redislocation. Redislocation was developed in one patient who played ice hockey at 2 months after operation and in one patient who played soccer at 8 months after operation. Subluxation was developed in one patient who had psychologic problem. Among 5 patients who had knot prob- lem, two patients had a operation of removal. In conclusion, Caspari's suture technique in arthroscopic Bankart procedure needs some modification on the insertion point of the guide pin and suturing technique. And arthroscopic Bankart procedure by Caspari's technique offers good cosmetic results, low perioperative morbidity, low complications except knot irritation, and excellent results by the Rowe's criteria for patients with anterior shoulder instability.

PURPOSE: To evaluate the relationship between the normal tissue complication probability (NTCP) of 3- dimensional (3-D) radiotherapy and the radiographic parameters of 2-dimensional (2-D) radiotherapy such as central lung distance (CLD) and maximal heart distance (MHD). MATERIALS AND METHODS: We analyzed 110 patients who were treated with postoperative radiotherapy for breast cancer. A two-field tangential technique, a three-field technique, and the reverse hockey stick method were used. The radiation dose administered to whole breast or the chest wall was 50.4 Gy, whereas a 45 Gy was administered to the supraclavicular field. The NTCPs of the heart and lung were calculated by the modified Lyman model and the relative seriality model. RESULTS: For all patients, the NTCPs of radiation-induced pneumonitis and cardiac mortality were 0.5% and 0.7%, respectively. The NTCP of radiation-induced pneumonitis was higher in patients treated with the reverse hockey stick method than in those treated by other two techniques (0.0%, 0.0%, 3.1%, p<0.001). The NTCP of radiation-induced pneumonitis increased with CLD. The NTCP of cardiac mortality increased with MHD (R2=0.808). CONCLUSION: We found a close correlation between the NTCP of 3-D radiotherapy and 2-D radiographic parameters. Our results are useful to reanalyze the previous 2-D based clinical reports about breast radiation therapy complications as a viewpoint of NTCP.

Aesthetic reduction of the labia minora has gained popularity. Hypertrophy of the labia minora is aesthetically and functionally unsatisfactory to some women. This study focused on one of the reduction techniques based on the degree of labial hypertrophy and the aesthetic preferences of the patient for labial edge color and contour. The five patients underwent labia minora reduction between August 2009 and August 2010. The ages ranged from 11~51 years (mean age, 29.2 years). All of the patients underwent medial central wedge resection and lateral hood resection of the labia minora. All patients were satisfied with the aesthetic appearance of the external genitalia, relief of chronic irritation, and improved hygiene; there were no complications. The patients reported no interference with usual daily activities or with intercourse. We describe a simple medial central wedge and lateral hood resection to reduce enlarged labia minora that depends on the degree of hypertrophy. These methods give the same satisfaction between pre- and post-menopausal women.

PURPOSE: To determine correlation between stress fracture of the posterior tibia and flexor digitorum longusmuscle injury caused by athletic or sporting activity during adolescence. MATERIALS AND METHODS: Eleven casesdiagnosed as stress fracture after X-ray and MR imaging of the lower leg were reviewed. With regard to eachfracture, the following features were noted: age, sex, and athletic or sporting activity of the patient, and site.Using MR imaging techniques, axial and sagittal T1 and T2 weighted images were obtained in all cases and T1-GdDTPA images in seven. RESULTS: The activities undertaken were running (n=3), football (n=2), ballet (n=2),taekwando (n=1), badminton (n=1), field hockey (n=1), and basketball (n=1). MR images revealed localized corticalthickness (n=11), linear intramedullary callus showing a low signal on T1 and T2 weighted images (n=9), marrowhyperemia (n=7), and flexor digitorum longus muscle injury showing a high signal on T1-Gd DTPA and T2 weightedimage (n=7). CONCLUSION: Stress fracture of the posterior tibia might be induced by flexor digitorum longusmuscle activity induced by athletic or sporting activities during adoleseence.

OBJECTIVE: The purpose of this study was to examine the strength of the knee and pulmonary function comparing collegians and hockey players in college. METHOD: KINdegreeCOM isokinetic dynamometer and medigraph were used to evaluate strength of the right lower extremity and pulmonary function to 30 male students comprising 15 hockey players and 15 collegians with no significant difference in age, weight, and height between the two groups. All subjects used their right lower limb as dominant limb. RESULTS: 1) The significant differences between collegians and hockey players were found in the peak torque at 60o/sec,180o/sec. 2) The siginficant differences between collegians and hockey players were found in forced vital capacity, forced expiratory volume in one second and expiratory reserve volume on the pulmonary function. 3) The significant correlation between isokinetic strength and pulmonary function were found in peak torque. CONCLUSION: It is turned out that hockey players in college have much better isokinetic strength and pulmonary function than collegians, so it is suggested this result have to be considered in selecting hockey players and exercise prescription.

The purpose of this study was to do the surveillance study of sports injuries which were suffered to National players of South Korea Team during the summer Asian Games 2010 in Guangzhou. All medical staffs of Korea Delegation were asked to report all sports injuries newly incurred during the Games on injury report form, and the physicians made clinical diagnoses of the injuries. Total 725 injuries (430 athletes) were reported, and 288 injuries (209 athletes) were newly incurred: 68 injuries (58 athletes) were recurrent with previous history, resulting in total incidence rate: 45.5 injuries/1000 athlete exposures (AE) (95% confidence interval [CI]: 40.1-50.6 injuries/1000 AE) and incidence proportion: 26% (95% CI: 23-29). The new injury was highest in athletics (n=37, 12.8%), hockey (n=26, 9.0%), and basketball (n=23, 8.0%). While 162 injuries (56.2%) were incurred during practice, 126 injuries (43.8%) were incurred in competition. The most frequent diagnoses were lateral ankle ligament sprain (n=28, 9.7%, 95% CI: 6.3-13.1), calf muscle cramp (n=23, 95% CI: 4.9-11.1), and hamstring strain (n=22, 95% CI: 4.6-10.7). The relapsed injury was highest in athletics (n=16, 23.5%), basketball (n=6, 8.8%), and wrestling (n=5, 7.4%). While 50 injuries (73.5%) were recurred during practice, 18 injuries (26.5%) were recurred in competition. The most frequent diagnoses of relapsed injury were calf muscle cramp (n=11, 16.2%, 95% CI: 7.4-25.0), low back strain (n=6, 8.8%, 95% CI: 2.1-15.6), and hamstring strain (n=6, 8.8%, 95% CI: 2.1-15.6). Our data indicated incidence rates, incidence proportions, characteristics and frequent diagnoses of acute and recurrent sports injuries during the games, therefore these results could provide relevant information for the sports injury prevention at elite level.

Commotio cordis is sudden death due to a non-penetrating chest wall impact in the absence of structural injury to the heart and chest wall. It usually occurs during sports games, like baseball, ice-hockey and soft balls, in young children. When objects (baseball, hockey puck, etc) strike the chest, a fatal arrhythmia like ventricular fibrillation can occur. We report a case of ventricular fibrillation that occurred after a light blunt trauma to the chest wall.

The authors report a case of T1-2 neurilemmoma removed by lateral parascapular extrapleural approach. A 28-year-old man was presented with smooth, well-marginated radiopaque mass in left superior mediastinum on plain chest X-ray. Magnetic resonance imaging revealed a sharply marginated isosignal lesion in the left thoracic inlet on T1 weighted image and strong enhancement on T1 enhanced image. A 15cm length hockey stick skin incision was made from C7 to T9 level. A 2x3cm sized orange colored soft tissue mass was detected over the pleura. The intercostal nerve, subclavian artery, and internal carotid artery were adherent with mass. After gentle dissection, the tumor was removed from nerve bundle. Pathologic examination of tumor revealed a neurilemmoma. The patient was discharged 3 weeks after operation without neurologic deficit.
