A retrospective analysis was conducted on ski injury collected in past 12 years, from 1982 to 1995, exception of 1986 and 1987 at the Young Pyeong Ski Resort in Korea. A total of 3,093,667 skiers during the 12 years period are cohort of this investigation. Of 3,093,667 skiers, 7,172 injuries were indexed by anatomic region and severity according to diagnosis on initial evaluation. The frequency of injury changes from 3.4 to 1.5 per 1,000 skier-days during the 12 years. The rate of upper extremity to lower extremity injury increased from 1:1.33 to 1:0.89 during the study period(P<0.005). The most common upper extremity injury pattern was simple injury including laceration and contusion(74.2%). The ulnar collateral ligament injury of thumb make up of 6.5% of all injuries. In conclusion, upper extremity skiing injury was related to 1) Skiers activity level, 2) Skiers skill, 3) Degree of fatigue, 4) Slope condition, 5) Improvement of ski equipment, and 6) Increased skiing population density.

We have experienced 40 cases of the tibial shaft fractures treated with Küntscher nail from 1979 to 1986. Authors analysed these cases and our own experimental study concerned with the shape of Küntscher nail. The shape of Küntscher nail for the tibial shaft fractures should be designed according to the type and location of the fracture. The proximally bent and distally straight nail is used for the extension fracture, proximally and distally bent nail or entirely bent nail is inserted for the flexion fracture of the tibia. The large nail(over 13 mm in diameter) may produce injury to the patella because it has minimal flexibility. In order to permit easy driven down of nail and prevent this injury, the nail should b. bent into three to four segments and the length of the longest segment should not exceed the permissible length of straight nail (Permissible length is distance from entrance of nail to posterior cortex of the upper fragment, where tip of the (nail impinged-about 12cm) The midpoint of the middle segment of dual dent nail is placed at the fracture site. The middle segment of the nail may bent anteriorly for flexion fracture and posteriorly for extension fracture, securing the dynamic fixation of the fracture.

Open discectomy is one of usual treatment for herniated intervertebral disc. We may expect the reduction of height of intervertebral disc due to decreased volume by partial resection of herniated disc. But the effect of decreased height of intervertebral disc space to posterior joint and spinal canal has not been identified, and the correlation between the amount of reduced height and the changes of range of motion has been undetermined. Thus, we analyzed radiologic changes of disc height and segmental motion by the flexion-extension view in 20 patients who had undergone discetomy for prolapsed intervertebral disc from June 1989 to January 1991 who could be followed up for 3 years or more. As a result, lumbar discetomy associates with 1) significant decrement of disc height (average 14%), 2) decreased disc motion of involved segment without hypermobility (average 34%), 3) hypermobility of adjacent segment, 4) and posterior facet overriding consistent with recurred low back pain.

Ossification of the ligamentum flavum(OLF) is a well recognized cause of acquired spinal canal stenosis resulting in myelopathy, radiculopathy, or a combination of both. OLF is extremely rare in caucasian patients, but is one of the most common causes of compression of the posterior thoracic spinal cord in Japan. In most cases, it has been found in the thoracolumbar regions, and rarely in the cervical region. It is frequently but not alwalys found in association with ossification of the posterior longitudinal ligament(OPLL) and may cause cumulative damage, if comhined with OPLL. We experienced a case of ossification of the ligamentum flavum and posterior longitudinal ligament with sacral radiculopathy, which was treated hy posterior decompressive laminectomy and removal of the ossified ligamentum flavum and posterior longitudinal ligament. The day after operation, the radiating pain and paresthesia dramatically improved.
