鲑鱼降钙素促进老年转子间骨折愈合的疗效观察

目的:观察鲑鱼降钙素促进老年转子间骨折愈合的疗效。方法:将40例老年患者随机分为2组:治疗组20例,肌肉注射鲑鱼降钙素;对照组20例,在相同的部位肌肉注射等量注射用生理盐水。自术后第1天开始,2组均连续用药3个月。用药后的第1、3个月复查X线片,观察骨痂生长情况。治疗前和治疗后3个月检测患者腰椎(L4)骨密度(BMD)及血清钙、磷、碱性磷酸酶等浓度。结果:所有患者均得到随访。术后第1、3个月X线评估发现,治疗组比同时期对照组的骨痂生成量多。治疗后3个月,治疗组腰椎(L4)BMD明显高于对照组(P<0.05),治疗组血钙浓度明显低于对照组(P<0.05),2组血磷浓度无明显差异(P>0.05),治疗组碱性磷酸酶明显高于对照组(P<0.05)。治疗组1例出现恶心、呕吐等胃肠道症状,2例出现面颈部潮红。结论:鲑鱼降钙素能显著促进老年转子间骨折的愈合。

Efficacy Observation of Salmon Calcitonin for Femoral Intertrochanteric Fractures Healing in Elderly Patients

OBJECTIVE： To observe the therapeutic efficacy of salmon calcitonin for femoral intertrochanteric fractures healing in elderly patients. METHODS： A total of 40 elderly patients with femoral intertrochanteric fractures were randomly divided into 2 groups. 20 cases in treatment group received intramuscular injection of salmon calcitonin and 20 cases in control group received equal dose of normal saline at the same site. Both groups were given medicine after operation for 3 months. The X-ray plate of 2 groups was examined at 1 and 3 months after treatment to investigate the condition of bony callus. The BMD of the lumbar spine at L4, the concentration of serum calcium, serum phosphorus and alkaline phosphate were measured before treatment and 3 months after treatment. RESULTS： All patients were followed up. The X-ray plate showed that the bony callus in treatment group was more abundant than in control group at 1 and 3 months after treatment. 3 months after treatment, the BMD of the lumbar spine at L4 in treatment group was significantly higher than in control group （P〈0.05）. The concentration of serum calcium in treatment group was lower than in control group （P〈0.05） and there was no significant difference in the concentration of serum phosphorus between 2 groups （P〉0.05）. The concentration of alkaline phosphatase in treatment group was significantly higher than in control group （P〈 0.05）. Gastrointestinal symptoms such as nausea and vomiting were found in 1 case, facial and cervical flush was found in 2 cases. CONCLUSION： The salmon calcitonin can significantly promote the healing of femoral intertrochanteric fracture in elderly patients.
