Enchondroma is a benign tumor mainly developed in the hand and uncommon in the foot. Even if it is in the foot, most are in the phalanges and distal metatarsals of the foot. Enchondroma in the calcaneus is very rare. A 44-year-old male suffered from left heel pain for several months, authors treated it with curettage and bone graft, it was histologically confirmed as an enchondroma in the calcaneus. The authors presented a rare case presentation of an enchondroma in the calcaneus with pain.

Purpose: To evaluate the efficacy of the preventive abduction brace in dementia patients after bipolar hemiarthroplasty of the hip. Materials and Method: A review of 30 patients who had dementia prior to bipolar hemiarthroplasty of the hip. 20 females and 10 males were evaluated and their mean age was 80.4 years old (range, 68 to -92 years old). The average MMSE-K in dementia patients was 14.2 (range, 8 to 20). The reasons for the bipolar hemiarthroplasties were femoral neck fractures in all the cases. We analyzed the dislocation rates of those who had preventive abduction braces applied prospectively. Results: The average follow-up period after hemiarthroplasty was 2.2 years. All 30 patients had preventive abduction braces and no dislocations occurred after the bipolar hemiarthroplasties. Conclusion: Hip dislocations were not detected in those patients who preventive abduction braces applied. The present findings suggest that having a preventive abduction brace will definitely reduce the dislocation rate in dementia patients who have difficulties with rehabilitation after their operations.

To evaluate a relationship of lumbar lordosis between asymptomatic group and low back pain group, lumbar lordotic angle was measured from standing lateral lumbosacral roentogenogram of 360 men and women between 20 and 49 years of age. We excluded the patients with back deformity, moderate to severe degenerative change of lumbosacral spine, leg length discrepency, and degenerative change of lower leg in both groups. The lumber lordodsis angle was measured with two ways, lumbosacral angle and lumbolumbar angle respectively. Two angles have a line parallel to the top of second lumbar vertebra as the proximal boundary. The distal border of the lumbosacral angle is a line parallel to the top of sacrum. The distal border of the lumbolumbar angle is a line parallel to the bottom of fifth lumbar vertebra. With statistical analysis of the results, we came to followiing conclusion: 1. The mean lumbolumbar angle was 33.62° +0.62° (SEM: standard error of the mean) and the mean lumbosacral angle was 49.91° +0.59° in asymptomatic group. 2. The mean lumbolumbar angle was 34.79° +0.68° and the mean lumbosacral angle was 50.35° +0.76° in low back pain group. 3. No significant difference in lumbosacral and lumbolsacral angle between asymptomatic and low back pain group was identified using general linear models procedure(P>0.5). 4. Analyzing the data by sex, no significant difference in lumbosacral and lumbosacral angle was identified using general linear models procudure(P>0.05). 5. Analyzing the data by age group, no significant difference in lumbosacral angle was identified (P>0.05), but significant difference in lumbolsacral angle was identified using general linear models procedure(P=0.0045).

In 1971, Harris introduced a metal backed acetabular cup to allow replacement of worn polyethylene cups and it has been popularly used now. In metal backed acetabular cup, dissociation between metal shell and polyethylene liner usually occurs with hip dislocation. We report a case of dissociation of polyethylene liner in metal bacded cup not associated with hip dislocation.

Since the use of Charnley hip prosthesis, total hip arthroplasty has been used for the treatment of coxarthrosis. However, aseptic lossening of the acetabular cup component in total hip arthroplasty remains the most common cause of failure and most serious complication. Cementless acetabular cup fixation in total hip arthroplasty is increasingly popular because of the high failure rates of cemented components, particularly in younger and more active patients. We have experienced 62 cases of CLS expansion acetabular cup developed by L. Spontorno, from January 1992 to January 1994. We analysed 41 CLS expansion acetabular cup components in 38 patients performed at the Department of Orthopedic Surgery, Kang Nam General Hospital with minimum follow up lyear(average 17.3 months). The object of this study is to evaluate the radiographic change of the cup inclination, horizontal and vertical migration of the CLS expansion acetabular cup by methods of Engh et al, and Callagham et al. The results were as follows: 1. The initial adequate contact fit were 39 hips and inadequate fit in 2 hips. 2. The initial acetabular inclination between 35 degrees and 55 degrees were 38 hips. 3. Vertical and/or horizontal migration was not occurred, except 2 hips which were complicated by deep infection. 4. Change of acetabular cup inclination than 5 degrees were not occurred. 5. Radiolucent line wider than 2mm was not found. 6. In final follow up of out 41 hips optimal stability was obtained in 39 hips, suboptimal stability was obtained in 2 hips, and definite instability was not found.

Intertrochanteric fractures are common in older age group. Recently better implant design and surgical technique have improved clinical results. But still many patients suffer from high morbidity and mortality, because of accompanying osteoporosis and various senile diseases. From January 1991 to June 1994, we treated 54 patients older than 70 years with intertrochanteric fractures of femur. Among them, 23 patients were followed up at our hospital and the other patients were informed from police station. Lost follow up was ten patients and final follow up were 44 patients. Mortality was analyzed for the detection of causative factors, such as age, sex, associated medical problems. type of fracture, degree of osteoporosis, type of operation, internal between injury and operation and duration of admission. The results were as follows; 1. 26 patients survived and 18 patients died(Mortality rate :40.9%) 2. 10 patients died within 1 year(Mortality rate :22.7%) 3. Mortality was related to associated medical problems, interval between in jury and operation and type of fracture, which were statistically significant(P < 0.05).

Central retinal artery occlusion occurs rarely as a complication of spine surgery in prone position, but is quite tragic. The suggested cause are hypotensive anesthesia and increased external ocular pressure by headrest, sand bag or others. We experienced a case of left central retinal artery occlusion(CRAO) after surgery of C4-5 fracture-dislocation using a horseshoe headrest and report this case.

PURPOSE: To analyze the causes of fixation failure of compression hip screw and evaluate outcomes of hip arthroplasty for reconstruction. MATERIALS AND METHODS: We reviewed 108 femoral intertrochanteric fractures that underwent compression hip screw between January 1997 and December 2007. Failure group (group I) contained 28 cases who had hip arthroplasty for failed compression hip screw and the control group (group II) contained 80 cases who had successive compression hip screw. We analyzed the causes of failure of compression hip screw and evaluated the results of hip arthroplasty for reconstruction. RESULTS: In group I, 21 cases (75%) were unstable fractures. Group II, 14 cases (17%) were unstable fractures. Tip-apex distance was 26.5 (18~35) mm in group I and 18.6 (8~22) mm in group II. Lateral wall fracture of greater trochanteric area was combined in 24 cases (85.7%) in group I and 9 cases (11.3%) in group II. Harris Hip Score improved from 33.5 (22~43) points to 84.2 (75~93) points after salvage hip arthroplasty. CONCLUSION: We considered the causes of failed compression hip screw to be fracture instability, increased tip-apex distance and presence of lateral wall fracture of greater trochanter. Hip arthroplasty was found to be a useful method for failed compression hip screw.
