The incidence of brachial plexus injuries in anterior shoulder dislocation remains relatively uncommon. A retrospective study was conducted to observe the natural neurological recovery of patients following these injuries over a 2-year period. Muscle power according to the Medical Research Council scale and sensation were measured from presentation to discharge. In 28 patients, the power grade of proximal muscles supplied by nine injured nerves failed to improve over a median follow-up of 5 months. There was no statistically significant improvement in sensation over a median follow-up of 6 months. Poorer recovery in muscle power score was related to advancing age, whereby every decade increased the risk by approximately 30%. Anterior shoulder dislocation with a plexus injury carries a risk of permanent nerve injury. Patients should be referred for specialist nerve assessment leading to rehabilitation and timely early nerve reconstruction, if indicated. IV.
在前肩脱位中，臂丛神经损伤的发生率相对较低。一项回顾性研究观察了这些损伤患者在 2 年内的自然神经恢复情况。从就诊到出院，通过医学研究委员会量表测量肌肉力量和感觉。在 28 例患者中，9 条受损神经供应的近端肌肉的力量等级在中位数 5 个月的随访中没有改善。中位数 6 个月的随访中，感觉没有统计学意义上的改善。肌肉力量评分恢复较差与年龄增长有关，每增加 10 年，风险约增加 30%。前肩脱位伴丛神经损伤有永久性神经损伤的风险。如果需要，患者应转介进行神经专科评估，以进行康复和及时的早期神经重建。IV.
