The accessory bones of the foot, such as the os tibiale externum, os trigonum and os peroneum are common, but the os intermetatar-seum is less known. We operated on a soccer player who had symptomatic os intermetatarseum of both feet, and who achieved a good result through excision of the accessary bone. We report upon this case and review the literature.

BACKGROUND: In order to investigate the effects of intensive training on cardiorespiratory response to maximal exercise in soccer players, graded excercise stress tests were carried out before and after the training, and the results were compared. METHODS: Fourteen male soccer players of a university team with the mean age and career of 19.9 and 7.8 years, respectively, underwent intensive training for approximately 20 weeks, 6 days a week and 4 hours a day, which included running of 2 km daily during the last 8-9 weeks. The symptom-limited maximal exercise test was done by Bruce protocol. RESULTS: After the training. HR max showed no significant changes but Vo2 max, O2 pulse and AT were increased approximately 13%, 12% and 10%, respectively. At maximal exercise, the V(E)/M2 was also increased 18%, but VE/MVV was significantly decreased owing to a marked increase in MVV. However, the rest of various ventilatory parameters showed no significant changes. CONCLUSION: These data indicate that the intensive training of about 20 weeks duration can further improve the level of cardiorespiratory fitness in the soccer players who have been regularly trained and are already highly fit.

This research sets out to define the relationship between stud morphology of soccer shoes and 5th metatarsal proximal stress fractures on soccer players by comparison and analysis. After the pre-survey of 132 soccer players in Gwangju, 107 players who seem to have a 5th metatarsal fracture were selected. We investigated the shape of the studs and asked whether they had ever had a 5th metatarsal proximal stress fracture. We also asked them some questions on factors, which cause stress fracture, such as what position they play, how long they have been playing soccer as athletes and average playing time. And we analyzed correlation between these several factors and whether they had ever had stress fracture using chi-square (x2) test and Logistic regression analysis. We concluded that soccer players who wore bar type studs shoes had a much greater possibility of stress fracture than soccer players who wore the round type. Also we learned that soccer players who play mid-fielder have a much greater possibility of stress fracture than soccer players who play other positions. And the result of logistic regression analysis of relevance between soccer shoes stud morphology and stress fracture shows a statistically significant odd ratio, 6.840. It has been suggested that the morphology of the soccer shoes stud has relevance to the occurrence of stress fracture. Therefore, according to the result of this study, soccer shoes with the round shape are more helpful in preventing 5th metatarsal proximal stress fracture than soccer shoes with the bar shape.

Although stress fracture of lower extremity is a relatively common, stress fracture of medial malleolus is rare. So we report one case. He is a 17 year old soccer player and successfully treated with surgical treatment (open reduction and internal fixation with one screw.

A stress fracture that occurs in the player such as soccer player etc is localized most often in 5th metatarsal bone and has been reported frequently about it. But rarely stress fracture on other metatarsal bone has been reported. So we report a stress fracture on 4th metatarsal bone, that occurred after stress fracture on 5th metatarsal base which had been treated by bone graft and fixation with intramedullary compression screw, was successfully treated with non-weight bearing and custom molded shoes.

The incidence of anterior cruciate ligament (ACL) injuries among female ballet dancers is much lower than among female soccer players, there is currently little research examining the landing error scoring system (LESS) of female ballet dancers and female soccer players. The purpose of this study was to investigate the LESS during drop vertical jump on ACL injury risk factors in female ballet dancers and female soccer players. Thirteen professional female ballet dancers and elite female soccer players participated in the study. Independent sample t-test was used to compare the LESS score between the groups with Bonferroni collection. The elite female soccer player group showed significantly higher stance width-wide, foot position-toe out, symmetric initial foot contact, overall impression and total LESS score than those of the professional ballet dancers.

BACKGROUND: In athlete's heart, functional and structural alteration are main features. We studied electrocardiograms(ECG's) and echocardiograms(UCG's) in soccer players before and after intensive training. METHODS: Fifteen soccer players with the mean age and career of 19.3 and 8.5 years,respectively,underwent intensive training for 5-5.5 months, which included running of 2 km daily during the last 2-2.5 months. Comparisons of ECG's and UCG's recorded before and after the training were made. RESULTS: The major abnormal finding in pre-training ECG's was high voltage being seen in 40% of the cases, and in UCG's left ventricular(LV) dilatation and/or hypertrophy or asymmetrical septal hypertrophy(ASH) were noted in approximately 80% of the cases. The incidences of these finding after the intensive training were essentially unchanged, and the mean of pre-and post-training fractional shortening(FS) and LV and left atrial dimensions were similar. The high voltage in ECG's showed no close correlation with LV dilatation or hypertrophy on UCG's. After the training, however, the mean values of the thickness of LV posterior wall and ventricular septum along with LV mass were significantly increased, and the right ventricular dimension was significantly decreased. CONCLUSIONS: The most frequent finding in ECG's and UCG's in soccer players, before and after intensive training,were high voltage, LV dilatation and /or hyperophy with or without ASH. The intensive training of 5-5.5 months duration caused no change in F8,but caused significant increase in the thickness of LV posterior wall and ventricular septum, and LV mass.

A 18-year-old male soccer player had painful triggering and occasional locking of the great toe caused by entrapment of the flexor hallucis longus tendon within the flexor sheath posterior to the right medial malleolus. After other treatment modalities failed, the condition was relieved by a surgical procedure that removed the nodule on the flexor hallucis longus tendon and the ganglion under flexor retinaculum. Tendon rupture was not found, although there was tendinitis.

The incidence of avulsion fracture of ischial tuberosity is reported to present in 1.4%–4% of hamstring injuries. The injury mechanism is known to be caused by a sudden forceful hip flexion in the extended knee with eccentric load to the hamstrings. Although the majority of hamstring injuries are strains of the muscle, avulsion fracture of ischial tuberosity occurs rarely. In this report, a 13-year-old boy with avulsion fracture of ischial tuberosity is presented. Successful clinical outcome was achieved with careful conservative management. Previous literatures including operative indications are reviewed.
