桡骨延长术治疗桡骨缺损伴下尺桡关节脱位   总被引:4,自引:0,他引:4  
采用桡骨延长加骨移植术治疗桡骨缺损伴下尺桡关节脱位,疗效满意。自1986年3月~1993年9月,共治疗12例。手术方法:切除桡骨缺损处瘢痕组织及两骨端硬化骨,打通骨髓腔;将骨撑开器插入骨断端.旋转延长螺杆,边延长边观察下尺桡关节复位至满意为止。骨缺损处用修整成圆柱状的自体髂骨块移植修复,并应用钢板螺丝钉固定。术后5个月全部达骨性愈合。平均随访4年5个月,按蔡氏[1]评定标准:优7例,良5例。本术式的优点是在桡骨延长时下尺桡关节自行复位,为临床提供一个新的治疗方法。  相似文献

Research on the relationship between body mass index (BMI) and cross‐sectional geometry of long bone diaphyses demonstrates that strength properties are significantly greater in obese versus normal BMI individuals. However, articular dimensions do not differ appreciably. If femoral head size remains constant, we hypothesize that the femoral neck remodels to accommodate greater loads associated with increased BMI. High‐resolution CT scans (n = 170 males) were divided into three BMI groups (normal, overweight, and obese) and two age groups (21–50 and >50). OsiriX software was used to obtain a cross‐sectional slice at the waist of the femoral neck. Cortical area (CA), total cross‐sectional area (TA), percent cortical area (%CA), circularity index (Imax/Imin), section modulus (Zpol), and second moment of area (J) were measured with ImageJ software. The effects of age and BMI were evaluated statistically. Pairwise comparisons in the younger group only detected significant differences between normal and obese males in the circularity index (P = 0.022). The older cohort showed significant differences in CA (P < 0.001), %CA (P = 0.004), Zpol (P = 0.007), and J (P < 0.001) between normal and obese groups. This study shows that the effects of obesity on the cross‐sectional geometry of the femoral neck are more pronounced in older males relative to younger males. Older males with increased BMI have greater cortical area and bone strength in the femoral neck relative to younger males, thus making the femoral neck less susceptible to fractures in obese individuals.

目的:探讨中药熏蒸疗法对尺桡骨骨折延迟愈合患者血液流变学及血清可溶性血管细胞黏附因子-1(s VCAM-1)、骨钙素(BGP)及人胰岛素生长因子-1(IGF-1)水平的影响。方法:将我院收治的110例尺桡骨骨折延迟愈合患者随机分为观察组和对照组,每组55例。对照组患者行重新复位再固定治疗,观察组在对照组基础上行中药熏蒸治疗。比较两组患者的临床疗效,分析各时点患者肘关节和腕关节活动功能恢复情况、血液流变学以及血清s VCAM-1、BGP及IGF-1水平。结果:治疗后观察组治愈率和治疗总有效率均显著高于对照组(P0.05)。第2、3疗程后观察组患者肘关节屈伸活动度、旋转活动度以及VAS评分均明显优于对照组(P0.05);治疗第2疗程以后观察组患者腕关节背伸和掌屈活动度明显优于对照组(P0.05);观察组患者各血液流变学指标较对照组均显著降低(P0.05);治疗第1、2、3疗程结束后观察组患者血清s VCAM-1水平明显低于对照组,血清BGP、IGF-1水平显著高于对照组(P0.05)。结论:中药熏蒸治疗尺桡骨骨折延迟愈合具有良好疗效,可明显改善血液流变学指标,降低血清s VCAM-1水平,提高血清BGP、IGF-1水平,利于骨折愈合和肘关节、腕关节功能恢复。  相似文献

Growth of fetal limb bones has been examined in a prospective cross-sectional study in 530 patients between 13 and 42 weeks of gestation by ultrasound. The length of the femur, tibia, humerus, and radius were measured in all cases, and fibula and ulna in 393 cases. For each week of gestation mean lengths (+/- 2 standard deviations) were calculated. All limb bones showed linear growth from 13 weeks to 25 weeks of gestation, after which the growth curve appeared nonlinear. A strong linear relationship (r greater than 0.98) between the BPD and bone length was found for each bone. In five aborted fetuses, prenatal sonographic measurements of the ossified diaphyses were compared with the postnatal radiologic measurement (30 limb bones). A good agreement was found (difference between ultrasound and X-ray measurements 0.7 +/- 0.5 [SD] mm or 3.0 +/- 2.4 [SD]%), indicating that ultrasound images the ossified diaphysis.  相似文献
