年龄因素对保守治疗发育性髋关节脱位患儿股骨头坏死发生率的影响

摘要

目的:探讨年龄因素对保守疗法治疗发育性髋关节脱位患儿股骨头坏死发生率的影响.方法:将68例(99髋)患儿根据患儿年龄大小分为≤12个月、13~15个月、≥16个月组3个年龄段.3个年龄段患儿均采用相同的保守治疗方法,统计治疗结果及股骨头坏死发生情况.结果:优良率12月以下患儿为93.75%,13~15个月以下患儿为81.48%,16个月以上患儿为70.00%.≤12个月年龄组与13~15个月年龄组比较,差异无统计学意义(P<0.05);13~15个月年龄组与≥16个月年龄组比较,差异无统计学意义(P<0.05);≤12个月年龄组与≥16个月年龄组比较,差异有统计学意义(P<0.05).99髋中出现股骨头缺血坏死41髋(41.4%,41/99),其中12个月以下患儿5髋(15.6%,5/32),13~15个月患儿18髋(66.7%,18/27),16个月以上患儿18髋(45.0%,18/40).股骨头缺血坏死发生概率3个年龄段间两两比较,差异均有统计学意义(P<0.05).结论:年龄因素与中西医结合治疗儿童发育性髋关节脱位后并发股骨头坏死发生率、治疗效果及脱位程度等密切相关.%Objective: To explore the influence of age on the incidence of femoral head necrosis of the children with developmental dislocation of the hip who accepted conservative treatment. Methods: All 68 children (99 hips) were divided into three groups according to their ages: younger than 12 months, 13 to 15 months, older than 16 months. All the children accepted the same conservative therapy, the results and the incidence of femoral head necrosis were statistically analyzed. Results: The excellent rate of the children younger than 12 months was 93.75%, the rate of the children aged from 13 to 15 months was 81.48%, and that of the children older than 16 months was 70.00%. The difference had no statistical meaning in the comparison between the children younger than 12 months and from 13 to 15 months (P<0.05); the difference showed no statistical meaning in the comparison between the children aged from 13 to 15 months and older than 16 months (P<0.05); the difference had statistical meaning in the comparison between the children younger than 12 months and older than 16 months (P<0.05). There were 41 hips with femoral head necrosis among 99 hips (41.4%, 41/99), five hips among the children younger than 12 months (15.6%, 5/32), 18 hips among the children aged from 13 to 15 months (66.7%, 18/27), and 18 hips among the children older than 16 months (45.0%, 18/40). The difference had statistical meaning in the comparisons among the children in three age groups in the incidence of femoral head necrosis (P<0.05). Conclusion: Age is closely related to the incidence of femoral head necrosis, therapeutic effects and the degrees of dislocation of the children with developmental dislocation of the hip treated by integrative medicine.
