ABSTRACT
PURPOSE: By achieving informations about sagittal shape and motion of each lumbar segment in normal subjects, we tried to get the standards useful in management of spinal disorders and fractures. MATERIALS AND METHODS: Thirty normal adults without any disorder on their back were adopted. L3 centered thoracolumbar (T-L) X-ray's including standing lateral, AP's in righ-tleft bending, and flexion- extension lateral were checked for each person. Cobb angles of each segment were measured. Statistical analysis was done for comparison by gender and correlation of each factors. RESULTS: Body shape of upper lumbar vertebrae was kyphotic but caudal bodies are changed into lordotic gradually. Disc angle was lordotic in all the discs. Segmetal motion in sagittal plane was greatest at L4-L5 (18.6degrees). However, segmental motion at coronal plane was largest at L3-L4 (12.6degrees). CONCLUSION: We achieved Korean standard of shape and motion of each lumbar segment. Proportion of each factor contributing to total lumbar lordosis was evaluated also.

Periprosthetic acetabular fracture after total hip arthroplasty is relatively uncommon but can occur in high-energy trauma or in patients with bone loss secondary to osteolysis. We encountered a periprosthetic acetabular fracture after minor trauma. The fracture was minimally displaced, and was treated conservatively. After eight-weeks non-weight-bearing, the fracture was healed but the acetabular cup had migrated. Acetabular revision was performed with morcellized allograft and non-cemented acetabular cup. At the one-year follow-up, the injured hip showed good range of motion with a stable acetabular component.

PURPOSE: To compare the results of open fixation and closed percutaneous pinning in managing Jakob stage II lateral condylar fractures of children's elbow. MATERIALS AND METHODS: Since Febuary 2000, We operated 21 children with Jakob stage II lateral condylar fractures of elbow. Eleven of the 21 were treated with closed percutaneous pinning, open fixation was done to the other 10 children. Each patient was evaluated about range of motion, carrying angle, scar satisfaction and radiologic findings for comparison between closed pinning and open fixation groups. RESULTS: Open fixation group showed 3.8 degrees decrease of elbow motion while closed pinning group showed no significant decrease. Carrying angle and radiologic findings were not different between the two groups. Open fixation group expressed dissatisfaction to their scars (average 5.2 cm) whereas all the patients of closed pinning group were satisfied with their functional and cosmetic outcomes. CONCLUSION: In managing Jakob stage II lateral condyle fractures of children's elbow, closed percutaneous pinning was thought to be superior to open fixation because of the same functional outcome and much better cosmetic results.

Cauda equina syndrome develops as rapidly progressive neurologic deficit of lower extremities and urogenital system often resulting in serious outcome such as complete irreVersible paraparesis. Therefore prompt diagnosis and decompression is mandatory. However, if it occurs after childbirth, it may be overlooked being regarded as symptoms related to pregnancy and delivery. We experienced a cauda equina syndrome by ruptured disc in a 32-year-old woman just after Caesarian section in a local obstetric clinic who was transferred to us 2 days after development of progressive neurologic deficits. We managed her with prompt decompressive surgery and achieved favorable result. Because of the importance of early detect and prompt decompression for cauda equina syndrome and possible occurrence at perinatal period, we report this case reviewing the literature especially concerning about pregnancy and cauda equina syndrome.
