Purpose: The purpose of this study was to evaluate the clinical and radiological results of total hip arthroplasty using a proximal modular femoral stem in patients who had secondary coxarthrosis associated with a deformed femur. Materials and Methods: Forty-two patients (45 hips) with secondary coxarthrosis were evaluated after primary total hip arthroplasty using an S-ROM proximal modular femoral stem, between January 2001 and March 2004. The average follow-up was 44 months (range, 24 to 60 months). The mean age of the patients was 48.5 years old and there was a predominance of female patients (65.5%). The preoperative diagnoses included 26 cases of developmental dysplasia of the hip, 13 cases of sequalae of LCP, 2 cases of epiphyseal dysplasia, 3 cases of sequalae of pyogenic arthritis, and 1 case of congenital coxa vara. Results: The average Harris hip score improved from 52.2 points to 85.5 points. All the femoral stems demosntrated stable fixation, which included 37 cases by bony ingrowth and 8 cases by stable fibrous ingrowth. Neither osteolysis nor progressive radiolucent lines around the femoral stems were found at the latest follow-up. Postoperative complications included: 2 cases of hip dislocations, 1 case of periprosthetic fracture, 1 case of infected cup loosening, and 1 case of sciatic nerve palsy. Overall, forty-one hips (91.9%) exhibited excellent or good clinical results at the most recent follow-up. Conclusion: For advanced secondary coxarthrosis, total hip arthroplasty with use of a proximal modular femoral stem yielded good mid-term results based on clinical and radiological criteria.

Congenital dislocation of the hip has been known as one of the most common congenital anomalies in the orthopedic field since the time of Hippocrates (460-357 B.C.). The occurence of C.D.H. in twin babies is extremely rare thus few if any papers have been reported. During the period of January 1971 through June 1976 the authors have treated a total of 49 cases as inpatients. Two of these were twin babies. In both cases the hip was surgically reduced and followed by open reduction and femoral derotation osteotomy. Clinically and radiologically the results were good during the duration of follow-up seven months after operations.

Fixation failure is a major complication of intertrochanteric fracture. The causes of fixation failure were assessed in a series of 80 patients with intertrochanteric fractures, which had been internally fixed with either a sliding hip screw or a Gamma interlocking nail. The overall rate of fixation failure was 16.3%, in which the cutting-out of the implant from the femoral head was the only cause of the instance. The cutting-out rate was influenced by the accuracy of fracture reduction, the position of implant placement within the femoral head, and the bone mineral density. Anatomical reduction and the central placement of implant within the femoral head showed the most excellent results compared to other treatment modalities. Age, gender, fracture type and a kind of fixation implant had no significant effect. Our results showed that the intertrochanteric fractures should be reduced as anatomically as possible and it is essential that the central placement of the implant within the femoral head be obtained.

The present study was intended to examine the effect of sodium vanadate on contractility of vascular smooth muscle. Aortic ring preparations were made from the rabbit thoracic aorta and endothelial cells were removed from the ring. The contractility of the aortic ring was measured under various conditions. The results were summarized as follows; 1) Sodium vanadate induced contraction of vascular smooth muscle in a dose-dependent fashion. 2) The contractile effects were not blocked by treatments with adrenergic blocking agent(phentolamine) and indomethacin, indicating the direct action of the drug on vascular smooth muscle. 3) In the presence of ouabain, Na(+)-K(+)-ATPase inhibitor, sodium vanadate still increased the contractility of vascular smooth muscle. 4) Treatment with 4.4'-diisothiocyanostilbene-2.2'-disulfonic acid(DIDS) blocked completely the contractile effects of sodium vanadate. 5) In the presence of verapamil, lanthanum and ryanodine, the contractility of the vascular smooth muscle by sodium vanadate was decreased. From the above results. it was suggested that sodium vanadate acts directly on vascular smooth muscle and causes contraction. It was probably due to inhibition of Ca(++)-ATPase in plasma membrane as well as increasing the release of Ca(++) from sarcoplasmic reticulum and Ca(++) influx across the plasma membrane, but not inhibition of Na(+)-K(+)-ATPase.

Caffeine has been known to induce the contraction of rabbit aortic ring resulting from Ca2+ release from the intracellular stores. But in contrast, contraction of aortic ring induced by depolarizing agents or agonist was reported to be suppressed by caffeine. The present study was intended to examine the effect of caffeine on Ca2+ movement across the plasma membrane and actomyosin ATPase activity of vascular smooth muscle to elucidate the modes of action of caffeine on the vascular smooth muscle. Aortic ring preparation were made from the rabbit thoracic aorta and the endothelial cells were removed from the ring by gentle rubbing. The contractilty of the aortic ring was measured under varying conditions, and Ca2+ influx across the membranes of the aortic ring was measured with Ca2+ sensitive electrode with and without caffeine and the effect of caffeine on actomyosin ATPase activity were measured by modified Hartshrone's method. 45Ca wash out curves with and without caffeine were studied by Richard's method. The results were summarized as follows: 1) Caffeine inhibited the contractilty induced by norepinephrine. high K+, and histamine. but caffeine alone induced a transient contraction of vascular smooth muscle. The caffeine induced contraction was demonstrable even in the absence of external Ca2+. 2) Caffeine increased 45Ca efflux from vascular smooth muscle. 3) In the presence of propranolol, the inhibitory effect of caffeine on epinephrine induced contraction still persisted. 4) Caffeine decreased norepinephrine induced Ca2+ influx through the plasma membranes of aortic ring. 5) Caffeine decreased the actomyosin ATPase activity of vascular smooth muscle. From the above results, it is suggested that caffeine induces the contraction of vascular smooth muscle by release of Ca2+ from intracellular Ca2+ stone, but inhibits drug-induced contraction by decrease of Ca2+ influx across the plasma membranes and a decreased Ca2+ sensitivity of contractile protein in vascular smooth muscle.
