摘要
本研究使用14只成年猕猴,1只作对照,13只按 Henny 氏操作完成单侧髁突高位切除术,用关节解剖、X线片、组织切片、透射电镜和扫描电镜超微结构研究术后组织修复和关节继发性改建。发现术后髁突形态和组织结构可恢复正常,无明显和持久性并发症;手术易于引起关节盘下腔面浅层组织损伤,但并不引起盘突粘连;关节结节因髁突高度降低而代偿性增高;非手术侧关节无病理改变。本文还对组织修复与改建的机理进行了探讨。
The repair process was researched with gross anatomy,X-ray film,microscopy andultrastructural microscopy following unilateral high condylectomy.The results showedas following:1.The animals recovered from operation,no any apparent and persistent complication.2.The gross shape of the condyle had been restored at 12 weeks,and histologicarchitecture at 24 weeks.But the changes of ultrastructure and remodelling on thecondyle cartilage were still present at 40 weeks.3.The injuries of the disks on the superficial layer of lower surfaces had been causedas a result of operation.But there are not any adhesions between the condyle andthe disk although the repair was very slow.4.The adaptive remodelling in the eminences occured resulting from the decrease ofthe condylar height.5.No any changes in the unoperated joints.
