Norm-Referenced Criteria for Isokinetic Strength of the Lower Limbs for the Korean High School Baseball Players / 대한스포츠의학회지

This study concerns norm-referenced criteria for isokinetic strength of the lower limbs for the Korean high school baseball players. Two hundred one high school baseball players were participated in this study. They didn't have any medical problem at the lower limbs. Each test was conducted four times in the ankle plantar flexion/dorsiflexion test at 30°/sec speed, knee flexion/ extension test was conducted four times at 60°/sec speed. Humac Norm (CSMI, USA) system was used to obtained the value of peak torque, peak torque % body weight. The results were presented as a norm-referenced criterion value using 5-point scale of cajori, by 5 group (6.06%, 24.17%, 38.30%, 24.17%, and 6.06%) and a few suggestions from this study as follows. The provided criterion of peak torque and peak torque % body weight are very useful information for baseball palyers, baseball coach, athletic trainers and sports injury rehabilitation experts, to utilize as an objective clinical assessment data.

Trapezial Fracture in Golf Player: Case Report / 대한정형외과학회잡지

The carpo-metacarpal joint is important for thumb function and for strong pinching and grasping. Inadequately treated fracture of the trapezium can produce long term morbidity. Solitary fracture of the trapezium are uncommon, compose less than 3% of all carpal fractures in adults. However such fractures are very rare in growing patients. Routine anteroposterior (AP) and lateral radiographs of the wrist often fail to show these fractures because of the overlapping trapezoid. Special radiographic views have been described (Robert's view) to detect this fracture. Computer tomography (CT) was found to be essential for the diagnosis and proper treatment of the described injury. We report a case of sagittally split fracture of the trapezium associated with a subluxated carpo-metacarpal joint of the thumb that occurred while playing golf, which was treated by open reduction and percutaneous pinning using two K-wires.
