Stress fractures of the anterior tibial cortex are prone to complete fracture because these stress fractures occur on the tension side of the bone. Recently, surgical treatments are preferred in high-performance athletes requiring rapid return to sports. We report our experience of a case in which stress fracture of the anterior tibial cortex was treated using anterior tension band plating in a male athlete and successful bony union and rapid return to sports were achieved.

Stress fractures of the patella occurring in athletes are quite rare and only 23 cases have been introduced in English literatures. Stress fractures of the patella are classified into two types: transverse and longitudinal. They are mostly seen in the distal one-third of the patella on a plain lateral radiograph. We present here a 16-year-old female basketball player with a stress fracture of the patella. Her serial radiographs demonstrated progression of the fracture including a lytic cortex lesion, known as the gray cortex sign for early stage stress fractures, in the distal one-third of the patella on plain lateral radiographs. In addition, we introduce a surgical technique using non-absorbable suture ligatures (No.2 Ethibond) for a displaced transverse stress fracture of the patella when the extensor mechanism is intact. The ligatures are passed through into the patella using suture passers and simply tied down over the top of the patella. In our case, it led to neither hardware-related nor circumferential loop-related irritation postoperatively.

Stress fractures of the proximal phalanx of the great toe are rare. This fractures have been associated with halux valgus deformity in most reports. We performed open reduction and internal fixation with distal chevron osteotomy for the stress fracture of the proximal phalanx of the great toe in a basketball player with hallux valgus, and obtained successful bony union and rapid return to sports.

PURPOSE: To evaluate the usefulness of magnetic resonance imaging(MRI) and ultrasonography(US) for thediagnosis of jumper's knee in high school basketball players. MATERIALS AND METHODS: In order to detect clinicalcases of jumper's knee, 40 sites of patellar tendon in 20 knees of ten basketball players were assessed by anevaluation of personal history and physical examination. US and MRI were used for detecting compatible findings ofthis condition ; the diagnostic criteria were hypoechoic focus with focal thickening as seen on US, and increasedsignal intensity with focal thickening as seen on MRI. As an early finding of jumper's knee a new sonographiccriterion of focal hypoechoic focus with or without focal thickening, was also applied. RESULTS: At 19 of 40sites(48%), clinical jumper's knee was diagnosed. For the detection of this condition according to known cliteria,sensitivity and specificity were, respectively, 63% and 100%(US) and 32% and 90%(MRI). Using the new criterion,the sensitivity and specificity of US were 84% and 76%, respectively. CONCLUSION: On the basis of known US andMRI criteria for jumper's knee, the sensitivity and specificity of US were higher than those of MRI. We suggestthat hypoechoic focus without focal thickening oas seen on US, is an early finding of jumper's knee.

A 20-year-old woman presented with 2-year history of low back pain. She is a basketball player. There was neither major traumatic episode nor history of febrile illness, On plain roentgenograms, sclerosis and slightly decreased height of L5 vertebral body was detected while the intervertebral disc spaces were intact. We found that L5 body was destructed by materials showing high signal intensity on T2 weighted images and connecting the two adjacent disc spaces on MRI. The initial diagonsis included bone tumors. Vertebrectomy was done and the intravertebral material was revealed as degenerated nucleus pulposus.

OBJECTIVE: To assess the jumper's knee for the symptoms and diagnostics by MRI and ultrasonography in basket ball players. METHOD: Twenty knees of 10 basketball players with chronic knee pain were assessed by the history taking, physical examination and diagnosis by magnetic resonance imaging and ultrasonography. Their average age was 17.4 years. Stanish classification is used for grading the symptoms of jumper's knee. RESULTS: Nine proximal patellar tendons were diagnosed as jumper's knees (45%) and 11 distal tendons were diagnosed as jumper's knees (55%). In ultrasonographic findings, average proximal patellar tendon thickness was 4.5 mm+/-1.2 mm, and distal patella tendon thickness was 7.1+/-1.1 mm. Sensitivity was 63% (12/19) and specificity was rated as 100% (21/21). By the MRI findings, sensitivity was rated as 32% (6/19) and specificity was rated as 90% (16/21). Study between the patient's clinical severity level by Stanish classification and thickness of patellar tendon showed no significant correlation (<0.5). CONCLUSION: The ultrasonography to be more convenient and easier as a diagnostic method for the jumper's knee than MRI.

Recent neuroimaging studies indicate that learning a novel motor skill induces plastic changes in the brain structures of both gray matter (GM) and white matter (WM) that are associated with a specific practice. We previously reported an increased volume of vermian lobules VI-VII (declive, folium, and tuber) in elite basketball athletes who require coordination for dribbling and shooting a ball, which awakened the central role of the cerebellum in motor coordination. However, the precise factor contributing to the increased volume was not determined. In the present study, we compared the volumes of the GM and WM in the sub-regions of the cerebellar vermis based on manual voxel analysis with the ImageJ program. We found significantly larger WM volumes of vermian lobules VI-VII (declive, folium, and tuber) in elite basketball athletes in response to long-term intensive motor learning. We suggest that the larger WM volumes of this region in elite basketball athletes represent a motor learning-induced plastic change, and that the WM of this region likely plays a critical role in coordination. This finding will contribute to gaining a deeper understanding of motor learning-evoked WM plasticity.

PURPOSE: To evaluate etiology, risk factors and clinical features in eyes with sports-related injuries. METHOD: A prospective evaluation of all patients presenting with a sports-related ocular injury was conducted at Dongguk University Pohang Hospital from January 1999 to December 1999. RESULT: There were 29 patients, representing 8.0% of all ocular trauma patients. Male was injured more often than female by a ratio of 6.25:1, and the mean age was 25.8+/-14.3 years. Soccer accounted for 37.9% and basketball accounted for 13.8% of all injuries. The mechanism most frequently responsible for injuries was direct ball trauma(51.7%). Six patients(20.7%) wore spectacles, whereas none of patients wore protective eye wear, at the time of their injury. Lid subcutaneous hemorrhage or edema(12 eyes) was the most common injury, and corneal abrasion(11 eyes) and retinal edema(7 eyes) occurred frequently. Traumatic hyphema and traumatic iritis occurred in 5 eyes, respectively. CONCLUSION: Sports-related ocular trauma is one of the significant causes of ocular morbidity. Even though all sports-related ocular trauma is not preventable, increased education such as use of certified protective eye wear is needed if the frequency or severity of injuries is to be decreased.

PURPOSE: Laser Assisted In Situ Keratomileusis(LASIK) is a preferred method to excimer laser photore-fractive keratectomy. In our paper, we insist that postoperative care, especially to avoid postoperative trauma. is considered to be important. CASE: A 22-years old boy was transferred into our hospital due to injuried left eye during playing basketball. His eye was received LASIK(OD: -7.00 Ds=-1.00 Dc Ax 50, OS: -8.00 Ds=-1.00 Dc Ax167) 1 years ago and then loss of LASIK flap developed due to this trauma. Injuried left eye of his was irrigated and then he weared therapeutic contact lens. RESULT: After wound healing, hazziness of traumatic cornea developed. He received lamellar keratoplasty for flap loss and corneal hazziness after postoperative accidental trauma. After receiving lamellar kerato-plasty, he maintains relatively good visual acuity(0.5 X -4.00 Dsph with K-840). CONCLUSION: As to review personel experience of the authors-lamellar keratoplasty for a flap loss and corneal hazziness after postopertive accidental trauma, we consider that it is an important vision-related complication of LASIK in the life and we report this unusual late complicated case with a review of available literature.
