作者报道了1957～1990年间收治并经手术证实儿童半月板损伤的48例临床资料.着重评价了传统诊断方法的要点及价值,讨论了仪器检查的价值与适应症.随诊1～36年.虽然临床疗效比较理想,但术后关节退变出现早而严重,故对儿童半月板全切除术应持慎重态度.藉助关节镜早期诊断和治疗,最大限度保留半月板是努力方向. 相似文献

研究目的：研究半月板全切对膝关节软骨的影响,从而为临床治疗半月板损伤方法的选择提供理论依据;研究方法：采用动物实验方法,在克膝关节采用内侧半月板切除术式,应用组织学,组织化学,免疫组化,扫描电镜,同位素标记放射自显影等方法观察术后,5、10、15、20、25和30d膝关节的关节软骨变化;主要结果和结论：兔内侧半月板切除后,导致关节不合槽运动,早至5d即可发现关节软骨细胞和蛋白多糖改变,并随时间的延长而进行性加重。但软骨表面的玻溃,胶原网架的断裂则迟至术后20d出现。因此,半月板切除可导致肯关节病的发生,而软骨细胞的改变是导致骨关节病发生和发展的关键因素;建议：对运动员半月板损伤应尽早处理,尽量不采用全切的术式,应用关节镜对半月板成形,缝合可最大程度地降低由于半月板损伤对膝关节造成的不良影响。 相似文献

目的:通过对人体膝关节内侧半月板与外侧半月板多部位、多切面的力学实验,研究其生物材料力学的特征,对比其差异,有助于分析该结构发生损伤的机理,为损伤后的治疗、修复、人工材料置换等提供实验参考依据.方法:取右侧膝关节无病变,年龄在20～45岁之间的成年男性内、外侧半月板各6块.将半月板分为前角、体部和后角3部分,再对前角与后角进行水平面、额状面冰冻切片,体部进行水平面、矢状面冰冻切片,制作成标准试件.使用上海大学力学实验中心“生物材料力学性能测试系统”完成“一维拉伸试验”和“应力松弛试验”.实验数据经统计学处理,进行:1)内、外侧半月板前角额状面及水平面比较;2)内、外侧半月板后角额状面及水平面比较;3)内、外侧半月板体部矢状面及水平面比较.结果:1)内、外侧半月板瞬时弹性响应比较,前者的前、后角均显著大于后者,前者的体部显著小于后者(P≤0.05);2)内、外侧半月板各部位、各切面应力松弛率比较均无显著性差异(P＞0.05);3)外侧半月板不同部位、不同切面中有4项抗拉伸能力指标显著低于内侧半月板(P≤0.05).结论:1)外侧半月板前角与后角、内侧半月板体部粘弹性较差,抵抗瞬时外力的能力较弱,从生物材料的角度看可能在承受突然较强的负荷时容易发生损伤;2)内、外侧半月板各部位、各切面调整负荷的能力基本相同,运动时若注意关节运动幅度适度、准备活动充分,应能够避免因负荷不均造成的损伤;3)外侧半月板较内侧半月板抗拉伸能力弱,可能是其急慢性损伤更为多见的生物材料力学原因之一. 相似文献

目的:探索基于FMS训练的运动干预对半月板损伤康复的影响,以期发现针对半月板损伤康复的重要变项及有用范畴,得到推导性的理论与实验发现。方法:对1名病程2个月,经MRI检查诊断为左膝内侧半月板后角损伤Ⅱ度青年男性军校大学生,制动一周后,进行8周线性单周期训练,训练内容基于FMS训练的运动康复计划。在运动康复前后分别进行受伤部位疼痛测试、基本形态测试、运动能力测试、基本生理指标测试及下肢步态分析。结果:与训练前相比,8周训练后,疼痛程度由中重度疼痛逐渐降至轻中度疼痛;基本身体形态和运动能力指标方面,在身体形态方面体重和体指数呈下降趋势;心肺耐力方面经改良版Bruce方案检测最大摄氧量显著提高;骨骼肌耐力(引体向上、双杠臂屈伸、俯卧撑)和最大力量(卧推、下肢等速测试)方面均显著提高;协调能力(平板支撑+变向滑步)方面显著提高;动摇角度、最大动摇径、重心偏移均显著下降,平衡能力提高;无氧能力方面有所改善;下肢爆发力方面呈现出机能节省化的趋势;认知能力方面选择注意力和抑制控制能力提高。结论:对于半月板损伤患者而言,运用8周基于FMS训练的运动康复计划可在一定程度上提高患者的基础运动能力,基本的生理指标也发生一定程度的改善。 相似文献

目的：比较前十字韧带重建术（ACLR）后重返运动率和重返运动时机在分别采用自体移植物和人工韧带（LARS）患者间的差异。方法：纳入2004年1月—2010年12月于复旦大学附属华山医院运动医学科接受ACLR手术的病例后，收集术后重返不同强度运动的情况和相应的重返运动时机信息，以及患者伤前、术前、术后第1年、第2年、第3年、第5年、第7年、第10年的运动水平。统计学分析两组间重返运动率和重返运动时机的差异。结果：LARS组中，24例术后重返运动，重返率为96%；重返竞技体育18例，重返率为72%；重返娱乐活动6例，重返率为24%。自体HT组中，45例术后重返运动，重返率为90%；重返竞技体育21例，重返率为42%；重返娱乐活动24例，重返率为48%。两组患者在重返竞技运动率（P=0.016）上具有显著统计学差异。LARS组中，重返轻体育活动时间为术后（2.0±1.0）月；重返涉及膝关节扭转、急停变向运动时间为术后（3.5±1.4）月；重返竞技运动时间为术后（5.2±1.7）月。自体HT组中，重返轻体育活动时间为术后（3.9±1.4）月；重返涉及膝关节扭转、急停变向运动时间为术后（5.9±1.3）月；重返竞技运动时间为术后（11.1±2.4）月。两组患者在重返运动时机（轻体育运动，P＜0.001；涉及膝关节扭转、急停变向运动，P＜0.001；重返比赛，P＜0.001）均存在显著统计学差异。LARS组患者术后第1年、第2年Tegner运动评分均显著高于自体HT组。结论：术后远期随访结果显示采用LARS重建前十字韧带（ACL）的患者不仅重返不同水平运动时机显著早于采用自体HT患者，且在重返竞技运动率上拥有显著优势。 相似文献

It is commonly believed that a torn ACL or a damaged meniscus may be associated with altered knee joint movements. The purpose of this study was to measure the tibiofemoral kinematics of ACL deficiency with concomitant meniscus deficiency. Unilateral knees of 28 ACL deficient participants were studied while ascending stairs. Among these patients, 6 had isolated ACL injuries (group I), 8 had combined ACL and medial meniscus injuries (group II), 8 had combined ACL and lateral meniscus injuries (group III) and 6 had combined ACL and medial-lateral meniscus injuries (group IV). Both knees were then scanned during a stair climb activity using single fluoroscopic image system. Knee kinematics were measured at 0°, 5°, 10°, 15°, 30° and 60° of flexion during ascending stairs. At 0°, 15° and 30° flexion of the knee, the tibia rotated externally by 13.9 ± 6.1°,13.8 ± 9.5° and 15.9 ± 9.8° in Group I. Group II and III exhibited decreased external rotation from 60° to full extension. Statistical differences were found in 0°, 15°and 30° of flexion for the 2 groups compared with Group I. In general, the tibia showed anterior translation with respect to the femur during ascending stairs. It was further determined that Group III had larger anterior translation compared with Group IV at 0° and 5° of flexion (?6.9 ± 1.7 mm vs. 6.2 ± 11.3 mm, P = 0.041; ?9.0 ± 1.8 mm vs. 8.1 ± 13.4 mm, P = 0.044). During ascending stairs the ACL deficient knee with different deficiencies in the meniscus will show significantly different kinematics compared with that of uninjured contralateral knee. Considering the varying effect of meniscus injuries on knee joint kinematics, future studies should concentrate on specific treatment of patients with combined ACL and meniscus injuries to protect the joint from abnormal kinematics and subsequent postoperative degeneration. 相似文献

Height, mass and skeletal maturity (Fels method) were assessed in 135 elite youth soccer players aged 10.7-16.5 years (only two boys were ?11.0 years). Sample sizes, years of training and current weekly training volume by two-year age groups were: 11-12 years ( n = 63), 2.6 - 1.0 years and 4.1 - 1.7 h; 13-14 years ( n = 29), 3.1 - 1.6 years and 4.5 - 1.7 h; 15-16 years ( n = 43), 4.7 - 2.4 years and 6.1 - 2.0 h. The oldest age group included membersof the national youth team.Heights and masses were compared to US reference values,and skeletal age and chronological age were contrasted. The players were also classified as late, average ('on time') and early maturers on the basis of differences between skeletal and chronological age, with the average category including boys with skeletal ages within - 1 year of chronological age. The mean heights and masses of 11- to 12-year-old soccer players equalled the US reference values, while those of players aged 13-14 and 15-16 years were slightly above the reference values. The mean skeletal age approximated mean chronological age in players aged 11-12 years (12.4 - 1.3 and 12.3 - 0.5 years, respectively), while mean skeletal age was in advance of mean chronological age in the two older groups (14.3 - 1.2 and 13.6 - 0.7 years, respectively, in 13- to 14-year-olds; 16.7 - 1.0 and 15.8 - 0.4 years, respectively, in 15- to 16-year-olds). Seven boys in the oldest age group were already skeletally mature and were not included when calculating differences between skeletal and chronological age. The proportion of late maturing boys in this sample of elite soccer players decreased with increasing chronological age. Among 11- to 12-year-old players, the percentages of late and early maturing boys were equal at 21% ( n = 13). Among 13- to 14-year-old players, the percentages of late and early maturing boys were 7% ( n = 2) and 38% ( n = 11) respectively, while among players aged 15-16 years the percentages of late and early maturing boys were 2% ( n = 1) and 65% ( n = 28) respectively. The results of this comparative analysis suggest that the sport of soccer systematically excludes late maturing boys and favours average and early maturing boys as chronological age and sport specialization increase. It is also possible that late maturing boys selectively drop-out of soccer as age and sport specialization increase. 相似文献

Height, mass and skeletal maturity (Fels method) were assessed in 135 elite youth soccer players aged 10.7-16.5 years (only two boys were < 11.0 years). Sample sizes, years of training and current weekly training volume by two-year age groups were: 11-12 years (n = 63), 2.6 +/- 1.0 years and 4.1 +/- 1.7 h; 13-14 years (n = 29), 3.1 +/- 1.6 years and 4.5 +/- 1.7 h; 15-16 years (n = 43), 4.7 +/- 2.4 years and 6.1 +/- 2.0 h.

This paper explores socio-ecological factors and their interplay that emerge from a qualitative study and influence adolescents' physical activity and sport participation. A total of 13 boys and 7 girls active and inactive adolescents, from years 12 and 13 and different types of school (state and private), participated in semi-structured interviews. It followed a purposeful sampling selection from participants who participated in a previous larger study on physical activity levels. Findings highlight the influence of personal and social interplay, such as perceived competence, obesity and teasing from peers, and new social demands and personal preferences in adolescents' (dis)engagement in physical activity and sport. They also stand out how social and environmental factors affect their participation, such as family, boy/girlfriends, physical education and rural/urban places of residence. These factors appear to have an important impact on the construction of (in)active identities during late adolescence. Policy makers, exercise professionals and educators should be aware of these factors in order to improve health promotion strategies and social policies. Some recommendations are also indicated in the paper. 相似文献
