膝关节半月板血供的应用解剖学研究

Applied anatomic study on blood supply of meniscus

目的 探讨正常成人半月板血供解剖学特征,为临床上半月板损伤的治疗方法选择提供依据。方法 通过对一组正常成人新鲜半月板标本进行血管灌注、透明标本制作、半月板组织切片H.E.染色及CD34抗体免疫组化染色等方法处理以观察和研究半月板的血供。结果 获得与Amoczky半月板“红白分区法”相一致的半月板血供结论;发现半月板前后角部及其周围组织血管血供丰富的特点;新提出半月板体部的血管血供呈分层现象的特征;明确半月板无血管区营养靠关节滑液供应的证据。结论 本研究进一步明确了半月板血供的解剖学特征,可为临床上半月板损伤治疗方法的选择提供可靠依据。

Objective To study the blood supply of meniscus of common adult in Shichuan province, discover the character, and offer the instructive basis for clinic treatment choice of meniscus injury. Methods To make blood vessel perfusion, make transparent specimen and others were treated as pathology histological slides and were stained by H. E. and CD34 antibody immunohistochemical method of 19 pairs fresh menisci of common adult. Then observe the distribution of meniscus blood supply by microscopy. Results Obtained the conclusion as Amoczky's 'Red-White zone', confirmed that there are plentiful blood supply in angle and surrounding area, suggested the meniscus behavior of stratify blood supply, and found the evidence of nutrition supply in meniscus no blood area. Conclusions The study provided the instruction of clinic treatment choice for menisci injury.
