The head patient with musculoskeletal trauma is a challenge to the orthopedic surgeon and its incidence is increasing markedly with the development of modern culture and a high velocity motor vehicle. So, for the purpose of studying the difference between lower extremity fracture concomitant with head injury and only lower extremity fractured patients, we studied the radiologic bone union time, serologic test and heterotopic ossification. For the control group we analysed each 10 patients of only femur and tibia fractures. The following clinical results were obtained by analysis of 46 patients of lower extremity fracture concomitant with head injury, experienced in the Department of Orthopedic Surgery, Yonsei University College of Medicine in past 5 years from Jan. 1980 to Dec. 1984. 1. The mean age was 24.5 yrs old (2~6 yrs old) and the prevalent age was 1st and 3rd decade, and the sex ratio between males and females was 2.8: l. 2. The most common mode of injury was auto-pedestrian injury (84.8%) and the other was falling down injury(15.2%) . 3. The common brain injuries were cetebral contusion with skull fracture (37.0%) and cerebral contusion only(34.8%) . Among 26 patients whos mental states were not alert, 23 patients recovered mental states completely. 4. Serum Calcium, Phosphate, and Alkaline Phosphatase level were no difference between the head injury with lower extremity fractured patients and only lower extremity fractured patients. 5. There were no evidence of early bony union in the patients with head injury. 6. The formation of callus were abundant in the patients of lower extremity fracture with head injury rather than the only lower extremity fractured patients. 7. The incidence of heterotopic ossification was 10.9% and all patients with heterotopic ossification were treated with physiotherapy and all patients recovered fully. 8. The incidence of complication was 17.3% and there was no fat embolic patients. In conclusion, there was no evidence of early bony union, but the callus formation was abundant in the patients of lower extremity fracture concomitant with head injury.

Eighty primary Harris-Galante Porus (HGP) total hip replacements were performed at Severance Hospital from January 1986 to January 1989. A minimum of 18 months follow-up was available for 80 hips in 72 patients, whose mean age was fifty two years. The most common presenting diagnosis was avascular necrosis (47.5%) followed by fused hips (10%), tuberculosis (10%), rheumatoid arthritis (7.5%). Complications included three calcar cracks and two immediate dislocations and 6 cases of mild myositis ossificans. There were no infections and no revisions. The mean Harris hip score was 93 points (range, 74–100 points) at two years. The thigh pain was in nine patients (11 per cent) at one year and in three patients (3 per cent) at two years postoperatively. Radiographic analysis revealed that, a progressive radiodense femoral line developed in 21 hips (26 per cent); a progressive acetabular line in 3 hips (4 per cent); and decreased proximal femoral density in 28 hips (35 per cent). There were no position change of the acetabula and femoral compent. We conclude that the early overall clinical results of HGP total hip replacements are encouraging, at average 30 months. The prognostic significance of the radiographic changes such ar radiodense lines, the changes of the proximal femur and cortical thickening, have to be determined with longer follow-up. Long term follow-up of uncemented HGP total hip replacement is necessary to evaluate the efficacy of such implants.

We performed twenty three cementless total hip arthroplasties(THA) on seventeen patients, all of whom were diagnosed with steroid-induced avascular necrosis of the hip (AVN). The average age of the patients was 41years, mean follow-up period was 41months (24-74months). The final average Harris hip score was 94 and overall results were excellent. On radiographic evaluation, 17 femoral components met the criteria for bone ingrowth(spot weld) but it was somewhat delayed. There was no evidence of loosening of the femoral and acetabular components. The results of this study suggest that long term steriod treatment does not prevent bone ingrowth. Cementless total hip arthroplasty appears to be a reasonable therapeutic option for steroid-induced avascular necrosis of the hip.

BACKGROUND: To assess the clinical utility of new DNA extraction method, the authors attempted PCR using mycobacterial DNA extracted by Chelex 100 ion exchange resin method for 63 clinical samples in patients with pulmonary tuberculosis and compared with proteinase K method, simultaneously. METHODS: We used Chelex 100 ion exchange resin for preparation of DNA. Decontaminated sputums were mixed with resin and incubated at 56degrees C and 100degrees C without opening tube. After centrifugation, supernatants were used directly as template for PCR. 245 bps in primary PCR and 188 bps in nested PCR were amplified and analysed by agarose gel electrophoresis EtBr staining. RESULTS: Chelex 100 ion exchange resin method is more simple, rapid and reliable than proteinase K method, and during sample preparation, carry-over contamination loss of amplificated DNA, influence of organic solvents and cross-contamination are diminished. The results of PCR products are interpreted more distinctively in Chelex 100 ion exchange resin method than proteinase K method. CONCLUSIONS: In the basis of the results, it could be suggested that extraction of mycobacterial DNA by Chelex 100 ion exchange resin is more simple, rapid reliable method than that of conventional method for detection of mycobacterial DNA in patients with tuberculosis by polymerase chain reaction.

A 58-year-old female with an episode of gross hematuria two months before and fever and chill for the past three days presented oliguric acute renal failure. She has taken NSAID intermittently for 18 years due to rheumatoid arthritis, and herb medicine for one week two months ago when gross hematuria developed. Physical examination revealed mild tenderness on costovertebral angles. Her blood pressure was 170/100 mmHg, the urinalysis showed >300 mg protein with many RBCs and 10-20 WBCs and the serum creatinine was 5.8 mg/dl. A renal biopsy performed on the 4th hospital day showed that it was overwhelmed by severe tubular lesions which reveal intratubular obstruction by massive erythrocyte casts and tubular necrosis. The glomeruli showed focal minimal crescents with many red blood cells entrapped in the crescents and in the capillaries. Immune deposits were not present. A renal failure resolved spontaneously and the patient was discharged three weeks later with creatinine of 2.4 mg/dl. In this patient, acute renal failure was considered to be due to a tubular lesion related to the glomerular bleeding from focal glomerulonephritis revealing minimal crescents.
