股骨骨折骨不连的生物力学因素及其对策 总被引:19,自引:2,他引:19
目的:探讨股骨骨折骨不连的生物力学因素,并提出相应的对策。方法:68例股骨干骨折骨不连经带锁髓内钉治疗,13例股骨远端骨折骨不连实施动力髁螺钉(DCS)内固定术,治疗同时行自体髂骨髓腔内外植骨术。结果:81例股骨骨折骨不连患者随访8~24个月,平均14个月。68例股骨干骨不连治疗后,有5例出现主钉或锁钉折断,经再次行带锁髓内钉内固定加植骨术治愈,其余患者不连端全部愈合;13例股骨远端骨不连经DCS内固定术后全部愈合。81例平均愈合时间为6.5个月。根据骨折愈合及功能恢复综合指标评定疗效,本组优54例,良21例,差6例,优良率92.6%。结论:股骨骨折骨不连的主要原因为内收肌群的生物力学因素导致内固定失败造成;股骨干骨折及骨不连手术内固定应以髓内固定为主,股骨髁部骨折及不连接应选用坚强的DCS系统。 相似文献

胫骨萎缩性骨不连骨折局部DSA的初步应用 总被引:2,自引:0,他引:2
目的研究胫骨萎缩性骨不连骨折区局部血液循环的改变情况。方法对12例骨折不愈合患者的骨折局部进行数字减影血管造影(DSA)检查,观察骨折不愈合处及周围软组织的血管形态变化、血管数目变化以及局部血液微循环时间的变化。同时观察12例正常人相应部位的DSA表现,对所得的2组数据进行统计学分析。结果骨不连患者的骨折局部的血管形态无明显变化,12例患者骨折区的血管计数均在正常范围之内,局部血液微循环时间2组比较具有显著的统计学差异(P<0.01)。结论研究表明,局部微循环障碍导致的供氧不足可能是骨不连的一个重要原因。 相似文献

One of the factors of the successful military career guidance Cadet schools students is preserving and promoting their health. Medical support of children and adolescents aged 10-17 years should include the full range of medical and preventive measures defined for this group. The state of providing outpatient care for pupils at the Cadet School in St. Petersburg was studied. These results show that full medical care in accordance with the standards can be based only on children's health clinics. It is important that the organization of medical support pupils cadet schools should be cooperate with civilian health care. 相似文献

ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. ‘Dose-response’ dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of ‘radiosensitivity’ enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method. 相似文献

Analysis of the results of the international comparison of activity measurements of a solution of Fe
The results of an international comparison of activity measurements of a solution of 55Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a 55Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.
The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison. 相似文献

A new method of non-surgical treatment of varicocele syndrome is described: it consists in sclerotherapy of spermatic vein by trans-femoral percutaneous catheterization with balloon-catheters. In 8 cases venous thrombosis has been induced by direct electric clotting. The techniques and a 6 months follow-up are discussed. It is pointed out that this procedure should be considered as the method of choice for tubular lesions and sub-fertility prophylaxis in young people and in childhood. 相似文献

目的探讨延迟性脾破裂误漏诊原因和预防措施.方法回顾性分析总结12例延迟性脾破裂中的诊断和误漏诊的经验与教训.结果本组延迟性脾破裂的误漏诊5例(41.66%).对多发伤与脾破裂并存可能认识不足,外伤史轻微或伤员隐瞒外伤史,缺乏腹痛-缓解-突然再腹痛的典型病史,缺乏“对冲性脾破裂”力学分析和整体化诊断思路等为其误漏诊的主要原因.结论详细的外伤史和全面系统检查,重视腹以外多发伤掩盖腹内脏器伤及延迟性脾破裂可能.确立外伤-腹内脏器伤-脾破裂整体化诊断思路.不间断地辅以B超检查脾形态学变化和腹内有无积液,腹腔穿刺确定有无血腹、X线胸腹部检查观察左侧胸肋角和膈肌运动情况、必要时CT检查以尽早发现脾包膜下血肿,降低延迟性脾破裂误漏诊率. 相似文献
