4.A Study on Correlation between Bone Mineral Density and Biochemical Parameters of Bone Metabolism in Female Patients with Systemic Lupus Erythematosus
Journal of Chinese Physician 2001;0(10):-
Objective To determine bone mineral density (BMD) and biochemical parameters of bone metabolism in premenopausal female patients with systemic lupus erythematosus(SLE), and investigate the correlation between them. Methods Lumbar and femoral BMD in 30 female patients with SLE was determined by dual energy X ray absorptiometry. In 30 female patients and 39 controls, the corrected serum levels of calcium, phosphorus, alkaline phosphatase, creatinine and albumin were measured by routine methods, and bone specific isoform of alkaline phophatase, propeptide of type 1 procollagen, deoxypyridinoline excretion, telopeptide of type 1 collagen, osteocalcin, parathyroid hormone, 25-OH vitamin D, testosterone, progesterone, estradiol, follicle stimulating hormone and luteinotropic hormone were measured by ELISA or RIA. Results According to the WHO criteria, 39% patients with SLE had normal BMD, 46% had osteopenia and 15% had osteoporosis at the lumbar spine; at the femoral neck 38.5% had normal BMD, 38.5% had osteopenia and 23% suffered form osteoporosis. All other bone resorption and formation markers measured were not significantly different except significantly higher corrected serum levels of albumin calcium (P=0.0001)and significantly lower osteocalcin level and phosphorus value(P=0.03,P=0.002) were found in the SLE patients. Of all sex hormones tested lower testosterone and higher follicle stimulating hormone concentration were seen in patients with SLE(P=0.001,P=0.42). Conclusion A high incidence of osteopenia and osteoporosis was found in premenopausal patients with SLE, which seems to be attributable, at least in part , to decreased bone formation in SLE patients.

ObjectiveTo observer the effect of autograft of semitendinosus and interference screws for reconstruction of lateral ankle ligaments. MethodsA total of 12 cases of injured lateral ankle ligaments were selected, including 7 males and 5 females with an average age was 29.4 years, with a course of disease from 3 to 6 months. All lateral ligaments were reconstructed by autograft of semitendinosus & bio-interference screws. A 4.5 mm diameter tunnel was drilled on the lateral ankle, where the tendon of semitendinosus was permeated through, both ends of semitendinosus tendons were fixed with bio-interference screws on talus of at the end of anterior talofibular ligament and calcaneus of at the end of calcaneofibular ligament, maintaining ankle neutral and moderate valgus position. Following operation, the ankle was fixed in neutral position and slightly valgus position with plaster cast. The wound healing, the outcomes of American Orthopaedic Foot and Ankle Society (AOFAS) score, Foot and Ankle Outcome Score (FAOS), and stress radiographic evaluation were assessed at the follow-up. ResultsAll 12 patients showed no infection and the wound healed well at the primary stage. At 3, 6, 12, 24 months after operation, all patients were followed-up. According to AOFAS and FAOS of preoperation and final follow-up postoperation, function of ankle in all patients was significantly improved (P<0.01), the scores of Chrisman-Snook group were more lower than this approach. No patients complained of instability of the ankle, and stress radiograph confirmed this improvement. ConclusionReconstruction of lateral ligaments of the ankle with autograft of semilendinosus & biointerference screws is a practical and reliable treatment, which restores stability and function of the ankle.
