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.

STUDY DESIGN: This is a retrospective study. OBJECTIVE: We wanted to evaluate the efficacy of epidural steroid injection (ESI) for treating lumbar spinal stenosis (LSS) SUMMARY OF LITERATURE REVIEW: Treatment for lumbar spinal stenosis has generally consisted of some form of conservative treatment or surgery. Surgery may be contraindicated in many stenotic patients because of their significant comorbidities. Therefore, conservative management is necessary for those who cannot or do not want to undergo surgery. MATERIALS AND METHODS: From January 2002 to June 2003, we retrospectively analyzed 128 patients, 55 years or older, who received ESI (s). The average age of the men and women was 47 and 81, respectively. Their mean age was 76 (age range: 55~84). The injection materials were 2 ml methylprodnisolone acetate (40 mg/cc) in combination with 3 cc normal saline and 3 cc lidocaine. The follow up period was 12 months to 30 months. We measured the outcomes by the duration and amount of pain relief, the change in functional status and the rate of performing surgery; patient satisfaction was assessed by a 5-item questionnaire. RESULT: Of the 128 participants, 31% reported more than 2 months of pain relief, 41% reported less than 2 months of pain relief and 27% reported no relief from the injection (s). Sixteen percent subsequently had surgery. Sixty-nine percent reported improvement in their functional abilities. Seventy-two percent were at least somewhat satisfied with ESI as a form of treatment. CONCLUSION: ESI is a reasonable treatment for LSS as it provided one third of our patient population with sustained relief and more than half with sustained improvement in function.
