隐性失血对双侧人工全膝关节同期置换手术的影响

[目的]研究双侧人工全膝关节同期置换术术后隐性失血的相关因素。[方法]对2005年2月～2007年2月44例双侧人工全膝关节同期置换术患者进行回顾性分析，通过Gross方程，根据身高、体重及手术前后的红细胞压积推算术后平均显性失血量及平均隐性失血量。[结果]平均总失血量2065ml，其中显性失血量1198ml，隐性失血量867ml，使用自体血回输患者总失血量为2180ml，隐性失血量为937ml（42％）；未使用自体血回输患者的总失血量是1950ml，隐性失血量是799ml（41％）；两组的隐性失血相比差异无统计学意义。[结论]双侧人工全膝关节同期置换术术后隐性失血量占总失血量的比例较高，且使用自体血回输不能完全满足机体恢复体循环的需要，在围手术期要特别注意及时补充血容量。     

回收式自体输血在儿童先天性髋关节脱位手术中的应用

[目的]探讨儿童先天性髋关节脱位的股骨和骨盆联合手术中洗涤式自体血液回收的应用方法与前景。[方法]2003年8月~2005年12月,17例先天性髋关节脱位股骨和骨盆联合手术中,使用Cell Saver 5血液回收系统行术中的血液回收。观察回输自体血液后的并发症发生情况,记录术中估计失血量、实际回收血量,以及回输血前后的Hb、Hct、P lt、PT、APTT、HR、BP、SPO2等的变化情况。[结果]17例患儿术中血液回收总量2 090 m l,平均每人(171±53)m l。其中4例出现一过性血红蛋白尿,其他无并发症。患者术前和术后24 h的Hb、Hct、HR比较差异有显著性意义(P<0.01);患者术前和术后24 h的P lt、PT、APTT、SPO2、BP比较差异无显著性意义(P>0.05)。[结论]儿童先天性髋关节脱位的股骨和骨盆联合手术中的血液回收是安全、有效的自体输血方式,明显节约异体血的用量,有效避免血液传播性疾病的发生。     

掌指关节置换术的研究进展

掌指关节置换术的不断发展，使其在手部慢性关节炎治疗中越来越受到关注。本综述掌指关节假体的生物力学研究和历史演变；归纳掌指关节置换术的术前评估与计划；介绍掌指关节置换术手术方法及注意事项；并总结了近十年来不同类型掌指关节假体的临床疗效。在手部慢性关节炎领域，假体设计和手术技术的不断完善，掌指关节置换术在减轻疼痛、矫正畸形和改善手部功能方面会得到更好的临床应用。     

胫骨髁间嵴增生在膝关节退行性变诊断中的临床价值探讨

本研究分３组，典型膝关节退行性变组（简称退变组）５０例，早期膝关节退行性变组（简称早退组）１５例，对照组３０例。分别测量每组Ｘ线片的内、外侧胫骨髁间嵴角与内、外侧嵴高平台比值。经统计学处理，两指标所测值在退变组与对照组及早退组与对照组之间有显著性差异（Ｐ＜０．０５），而退变组与早退组之间则无显著性差异（Ｐ＞０．０５）。结果表明：胫骨髁间嵴硬化变尖不仅是膝关节退行性变的特征性表现之一，而且是其早期Ｘ线征象。     

Radiographic study of osteoarthritic elbows in professional basebal pitchers

We examined radiographs of the elbows of the pitching arms of 79 professional baseball pitchers (mean age, 25.1 years; mean duration of professional career, 4.7 years) and noted the frequency and size of spurs, bone fragments, and intra-articular loose bodies according to site. The influence of duration of professional baseball career on these osteoarthritic changes was also investigated. The olecranon tip was the most frequent site of spurs (62/79; 78.5%), and fragmentation of the spur was detected in 17 joints. The frequency of spurs was also high at the medial margin of the olecranon, the tip of the coronoid process, the medial margin of the sigmoid notch, the medial margin of the trochlea and the olecranon fossa. In 38 subjects, spurs were observed at the distal portion of the radial notch of the ulna. However, few pitchers had osteoarthritic changes in the humeral capitellum or radial head. Intra-articular loose bodies were detected in 4 of 79 joints (5.1%), and bone fragments were present below the medial humeral epicondyle in 25 of 79 joints (31.6%). Osteoarthritic changes in the elbow joint appeared to be attributable mainly to traction stress and impingement associated with extension and valgus strain. Significant osteoarthritic changes were often found in professional pitchers whose careers exceeded 5 years.     

胚胎颅骨骨膜移植修复髋关节软骨大面积缺损

１９９０年５月～１９９４年４月，对４２例（４７个髋）关节软骨全厚缺损患者采用冷冻保存胚胎颅骨骨膜移植进行修复，其中１４例股骨头骨质Ⅳ期坏死者，同时施行带旋髂深血管蒂髂骨植骨。对３４例（３８个髋）进行了２年～６年（平均４０个月）随访。结果表明，按照吴之康髋关节人工置换术后疗效评定标准，优良２５例，很好５例，好３例，尚可１例。认为，与自体移植物修复关节软骨大面积缺损相比，这种方法无附加损伤，具有移植材料、形态与股骨头相似等特点，是治疗髋关节软骨大面积缺损的一种有效方法。     

骨与关节损伤治疗中存在的问题与对策

尽管骨关节损伤治疗已取得巨大进展,但仍存在许多问题,主要包括:对骨折治疗理念转变和微创外科概念的错误理解,对骨折治疗技术的不正确使用,忽视骨折分类方法和功能评定标准.正确的分析和解决这些问题会进一步促进创伤骨科临床实践和科研的进步.     

Clinical and radiological profile of symptomatic knee osteoarthritis in Malaysia

Aims: To create a clinical and radiological profile of patients with symptomatic osteoarthritis of the knee in Malaysia. Methods: One hundred consecutive patients presenting with symptomatic knee osteoarthritis at a private rheumatology clinic were profiled for demographic and clinical features. Anteroposterior weight‐bearing, skyline and lateral knee X‐rays were taken. Statistical Package for Social Sciences was used for data analysis. Results: Women predominated (93%). Fifty‐eight percent of the patients reported bilateral knee pain. Difficulty in walking, climbing and squatting was high (85%, 97% and 93% respectively). Patients with knee pain had a higher BMI than controls. Radiological abnormality, related to osteoarthritis was present in 97%. Osteophytes were generally tricompartmental while joint space narrowing was less evident in the lateral tibiofemoral joint than in the medial tibiofemoral joint and the patellofemoral joint. Almost half (49%) the patients manifested radiological varus deformity The severity of radiological abnormality increased with age. Although patients with unilateral pain had milder radiological abnormality, it tended to be bilateral. Clinically detectable hip abnormality and nodal osteoarthritis were uncommon, as was radiological chondrocalcinosis. Conclusions: Patients presenting with symptomatic knee osteoarthritis to a rheumatology service had a high degree of disability, radiological abnormality and varus deformity. Radiological abnormalities were essentially bilateral and tricompartmental.
