| 摘 要： | 目的区分因伸直位制动4周所致兔膝关节挛缩中的肌源性和关节源性成份。方法10只兔子的后肢右侧作为制动侧，左侧为对照侧。将其膝关节伸直位制动4周后，分别测量肌肉切断术前后两侧膝关节的关节活动度(ROM)，以反映肌源性成份所占的比例。结果制动侧和对照侧膝关节的ROM分别为79.5°和138.5°，行肌肉切断术后其ROM分别增加了8.7°±0.45°，11.6°±0.58°，肌源性成分在关节挛缩中所占的比例仅为14.75％。结论制动4周后，膝关节的ROM受限，其中肌源性成份所占的比例很小。

| Abstract: | Objective:To differentitate the myogenic from arthrogenic component of knee contracture resulting from being immobilized in extension for 4 weeks. Method:Ten rabbits were used as experimental animals. The right hindlimbs were immobilized with knee in extension for 4 weeks, while the left severed as controls. The range of motion ( ROM ) of both knees were measured before and after myotomy. Result:In immobilized and control hindlimbs, the mean ROM of the knee were 79.5°and 138.5°, respectively. The gain of ROM after myotomy in immobilized and control hindlimbs were 8.7° ±0. 45°, 11.6° +0.58°, respectively. Only 14.75% of the limitation of motion in ROM were accounted for by the myotomy component. Conclusion:After immobilizing for 4 weeks, the ROM of knee was significantly limited. However, the myogenic part was small and not different from normals. |
