Turner氏综合征的临床与骨改变分析(附15例报告) 总被引:2,自引:0,他引:2
目的通过对15例有详细的临床及影像资料的Turner氏综合征分析,探讨先天性卵巢发育不良综合征(Turner)的临床与骨改变特点。方法收集15例Turner氏综合征临床及骨骼X线平片,分析其表现。结果染色体核型分3型,第1型45,X,8例;第2型46,XX,5例;第3型46,XX/45,X,2例。X线表现有:骨质稀疏14例,掌骨征阳性8例,指骨优势9例,肘外翻10例,脊柱骨化不良5例,足趾趾节短9例,颅底凹陷11例。结论Turner氏综合征患者最终身高明显低于正常人群,智力低下,性发育不全。X线表现典型,骨改变对临床的诊断具有主要参考价值。 相似文献

学龄儿童掌指骨发育某些正常变异的观察 总被引:1,自引:0,他引:1
1980年和1990年对1259名城乡7~12岁学龄儿童掌指骨发育的正常变异进行了观察。结果证实,小指中节骨发育变异的检出率最高(总检出率14.7%),且男女儿童1990年此率均高于1980年(P<0.05),反映城市儿童该变异近10年有增高的趋势;1990年男女学龄儿童小指中节骨变异检出率城市明显高于农村(P<0.01);Ⅱ掌骨副骨骺总检出率3.8%,指骨骺核硬化总检出率2.2%,这两种变异男性明显高于女性.且无城乡差异。本观察各年龄组小指中节骨的变异同骨龄无规律性联系。 相似文献

Metacarpal and phalangeal lengths were measured on 1290 hand radiographs of Nigerian children, aged 3–16 years. The radiographs were obtained during a combined cross-sectional and longitudinal study of growth and development. There is a linear increase in tubular bone length with age in both sexes. The girls have higher values for all the bones up to the age of 13 years when the boys overtake them. Comparison of our data with those from North American children shows that the values amongst Nigerian children are higher than White, Black American and Mexican American children. Of particular note is the difference between Black American and Nigerian figures. It is postulated that the decreased metacarpophalangeal lengths in Black Americans compared with Nigerians may be due to gene dilution. 相似文献

Intraosseous schwannoma (neurilemmoma) is an extremely rare, benign neoplasm, constituting less than 0.2% of primary bone
tumors. It infrequently involves the bones of the hand. We present a case of intraosseous neurilemmoma of the metacarpal.

目的:比较克氏针与微型钢板置入内固定治疗掌指骨骨折的临床效果。方法选取2011年4月~2013年4月本科收治的掌指骨骨折患者81例,将其分为研究组和对照组。对照组采用克氏针治疗,研究组采用微型钢板置入内固定治疗,比较两组的优良率及相关临床指标。结果研究组的优良率为97.06%,明显高于对照组的80.85%(P<0.05)。研究组的手术时间、住院时间与对照组比较,差异无统计学意义(P>0.05),骨折愈合时间、延迟愈合率与对照组比较,差异有统计学意义(P<0.05)。结论给予掌指骨骨折患者微型钢板置入内固定治疗的效果优于克氏针,值得临床推广应用。 相似文献

Study DesignThis is a noninferior, single-blind, randomized controlled trial.IntroductionJoint stiffness is common after plaster cast immobilization for simple phalanx and metacarpal fractures in children. The limited literature suggests this joint stiffness in children resolves without one-on-one therapy; however, without robust studies confirming that there is no detrimental effect from withdrawing treatment, many children are still referred.Purpose of the StudyThe purpose of this study was to determine if an educational handout for self-management of stiffness is noninferior to one-on-one hand therapy for achieving full range of motion (ROM).MethodsParticipants were randomly assigned to group one who received the handout or group two who received hand therapy in addition to the handout. The ROM was measured by composite flexion and total active motion (TAM). The noninferiority margin was 10% difference between the two groups in the proportion of participants who achieved full ROM at two weeks after cast removal.ResultsSixty participants in each group completed the study. Group difference for composite flexion was 1.7% (95% CI: −3.9% to 7.2%), demonstrating noninferiority. Group difference for TAM was inconclusive at 8.3% (95% CI: −2.1% to 18.7%). Sensitivity analysis adjusting for participants with full composite flexion at the baseline resulted in the group difference for composite flexion of 3.1% (95% CI: −3.6% to 9.8%), maintaining noninferiority, but group difference for TAM at 10.4% (95% CI: 0.0% to 20.9%), was inconclusive with the handout group significantly worse.ConclusionAn educational handout is noninferior to hand therapy for achieving full ROM in composite flexion but not TAM. This needs to be taken into consideration for changing clinical practise. 相似文献

Study DesignThis is a two-group randomized controlled trial.IntroductionFinger stiffness after treatment for metacarpal fractures often occurs due to poor compliance to the conventional rehabilitation programs. Gamification has shown success in improving adherence to and effectiveness of various therapies.Purpose of the StudyThe purpose of this study was to evaluate whether gamification, using cost-effective devices was comparable with conventional physiotherapy in improving hand functions and adherence to rehabilitation in metacarpal fractures.MethodsA 2-group randomized controlled trial involving 19 patients was conducted. Participants were randomized to a control (conventional physiotherapy, n = 10) or interventional group (gamification, n = 9). The grips strength and composite finger range of motion were measured at the baseline and each follow-up together with Patient-Rated Wrist and Hand Evaluation scores and compliance.ResultsThere were no significant differences on improvements of grip strength (means difference 24.38 vs 20.44, P = .289) and composite finger range of motion (means difference 50.50 vs 51.11, P = .886). However, the gamification group showed better results in Patient-Rated Wrist and Hand Evaluation (mean 0.44 vs 8.45, P = .038) and compliance (P < .05). No adverse events were reported.DiscussionOur results suggest that gamification using a cost-effective device demonstrated similar effectiveness as conventional physiotherapy in post–metacarpal fracture rehabilitation.ConclusionsGamification using a mobile device is an inexpensive and safe alternative to conventional physiotherapy for hand rehabilitation after metacarpal fractures. It effectively serves as a guide for future development of cost-effective technology–enhanced therapy. 相似文献
