摘要
研究手术治疗臂丛神经损伤后三角肌、肱二头肌的恢复，探索周围神经损伤后影响肌肉恢复的组织形态学因素。通过１４例臂丛损伤患者行神经移位或移植治疗和随访，及实验室三角肌和肱二头肌各１０例标本的组织形态学研究，发现在条件相同的情况下肱二头肌的功能恢复优于三角肌。三角肌内Ⅰ型肌纤维的含量多，肌纤维在形态上趋向于动物的慢肌。提示三角肌恢复差的原因与其慢肌特性有关。
The recovery of the deltoid muscle and biceps brachial musclebllowing surgical treatment after brachial plexus injury were studied to explore the histomorphological factors affecting the recovery of the nerve injuried muscle,Fourteen patients were retrospectively reviewed in clinic and ten specimens fetched from either normal deltoid muscle or normal biceps brachial muscle were studied by histochemically in laboratory.It was found that the biceps brachial muscle recovered better than deltoid muscle when all the conditions were equal.There were more I type muscle fibers in deltoid muscle and the apperance of the muscle fibers in deltoid muscle tendell to be that in thes low muscles of animals。It was suggested that the reasons of poor recovery of the deltoid muscle were relatd to its slow muscle characters。
