观察针推结合治疗颈椎小关节错缝的临床疗效.将178例患者随机分成针刺组、推拿组和针推组进行对比观察.结果针推组痊愈率68.8%,高于针刺组27.8%和推拿组28.6%,经统计学处理(P<0.01),有显著性差异.针推结合治疗本病可使疗效互增,相得益彰.  相似文献

Most recent studies on procedures for stabilizing the glenohumeral joint focus on arthroscopic techniques. A relatively simple open procedure is the modified Putti-Platt procedure. The aim of these retrospective case series was to evaluate the functional outcome, patient satisfaction, and quality of life of patients who underwent this procedure. After a median follow-up time of 4.7 (P25–P75 1.7–6.8) years, fifty-one patients could be enrolled with a mean age of 25 (21–39) years. Five patients (10 %) reported re-dislocations. The median Constant score for the affected side was 84 (P25–P75 75–91). Median loss of motion in abduction, elevation, external rotation, and external rotation in 90° of abduction did not exceed 10° when compared to the healthy shoulder. A median Rowe score of 92 (P25–P75 75–95) was measured. The WOSI score and SF-36 showed excellent quality of life. The VAS proved high patient satisfaction with the outcome; 7.9 (6.8–9.5). We concluded that the modified Putti-Platt procedure leads to excellent outcome scores and only marginal restriction in range of motion combined with a high patient satisfaction. Our data prove that excellent results can be obtained with a relatively simple open procedure.  相似文献

背景:遗传性非息肉性结直肠癌(HNPCC)是一种由错配修复基因种系突变引起的常染色体显性遗传病,高度微卫星不稳定(MSI—H)为其分子生物学特征之一。目的:利用5个微卫星位点建立正常结直肠黏膜、结直肠腺瘤和癌组织的微卫星基因型,探讨HNPCC的MSI发生情况和MSI检测的临床意义。方法:纳入源自33个HNPCC家系的腺瘤28例和腺癌14例,其中4例为同步腺瘤-癌;以32例散发性结直肠腺瘤和24例散发性结直肠癌作为对照。选用BAT25、BAT26、D2S123、D5S346、D17S250五个微卫星位点行荧光标记聚合酶链反应(PCR),以GeneMapper软件分析PCR产物。通过与正常黏膜微卫星序列PCR片段长度进行比较,判定腺瘤和癌组织的MSI情况。结果:HNPCC腺瘤和癌组织MSI-H发生率分别显著高于散发性结直肠腺瘤和结直肠癌(64-3%对3.1%,71.4%对12.5%,P〈0.05)。4例同步腺瘤-癌均表现为MSI—H.其腺瘤和癌组织的MSI类型不同。结论:HNPCC腺瘤和癌组织MSI—H发生率高。同步腺瘤一癌来源于不同克隆。MSI检测可作为HNPCC的临床初筛方法。  相似文献

Objective

The purpose of this study was to establish consensus on a radiographic definition for cervical instability for routine use in chiropractic patients who sustain trauma to the cervical spine.

Method

We conducted a modified Delphi study with a panel of chiropractic radiologists. Panelists were asked to rate potential screening criteria for traumatic cervical spine instability when assessing cervical spine radiographs. Items rated as important for inclusion by at least 60% of participants in round 1 were submitted for a second round of voting in round 2. Items rated for inclusion by at least 75% of the participants in round 2 were used to create the consensus-based list of screening criteria. Participants were asked to vote and reach agreement on the final screening criteria list in round 3.

Results

Twenty-nine chiropractic radiologists participated in round 1. After 3 rounds of survey, 85% of participants approved the final consensus-based list of criteria for traumatic cervical spine instability screening, including 6 clinical signs and symptoms and 5 radiographic criteria. Participants agreed that the presence of 1 or more of these clinical signs and symptoms and/or 1 or more of the 5 radiographic criteria on routine static radiographic studies suggests cervical instability.

Conclusion

The consensus-based radiographic definition of traumatic cervical spine instability includes 6 clinical signs and symptoms and 5 radiographic criteria that doctors of chiropractic should apply to their patients who sustain trauma to the cervical spine.  相似文献

ObjectivesThe purpose of this study was to identify prospectively the anatomical and functional intrinsic risk factors for lateral ankle sprain (LAS) in adolescent athletes participating in team sports.DesignA prospective cohort study.SettingUniversity research laboratory.ParticipantsA total of 152 adolescent male athletes (age: 14.45 ± 2.96 years; height: 165.63 ± 15.33 cm; weight: 55.60 ± 16.56 kg; body mass index: 19.97 ± 3.58 kg/m2) participated in this study.Main outcome measuresThe participants were assessed during the preseason for previous ankle sprain history, navicular drop, tibia vara, Q angle, tibia torsion, knee recurvatum, and ankle ROM. LASs were prospectively recorded and diagnosed for two consecutive seasons (20 months).ResultsPrevious ankle sprain history (odds ratio [OR] = 60.911, p < 0.001), increased navicular drop (OR = 1.767, p < 0.001), and knee recurvatum (OR = 1.881, p = 0.002) were positively associated with the incidence of LAS. The receiver operating characteristic (ROC) analyses revealed the predictive potentials of previous ankle sprain history (the area under the ROC [AUROC] = 0.706, p < 0.001), navicular drop (AUROC = 0.906, p < 0.001), and knee recurvatum (AUROC = 0.724, p < 0.001).ConclusionAthletes with previous ankle sprain history, knee recurvatum, and especially navicular drop may have a greater risk of LAS injury. The data from this study can help therapists and trainers to identify people with a higher risk of LAS.  相似文献
