Carpal tunnel syndrome is a common cause of hand pain, sensory disturbance, and weakness affecting daily activities and quality of life. It is a frequent reason for medical consultation and up to 40% of patients are managed exclusively in primary care. Treatment goals are to relieve symptoms, improve function, and prevent disease progression to nerve damage. The two treatments that constitute standard care for most patients with first-time carpal tunnel syndrome are night splinting and local steroid injections. In a large-sample, US national database study (2009–13), 71% of patients with carpal tunnel syndrome were treated with immediate surgery without previous steroid injection. Evidence regarding effectiveness of night splinting in carpal tunnel syndrome is weak, optimal treatment duration is unclear, and the benefit is generally small.^,  Efficacy of night splinting has not been assessed in placebo-controlled trials, and efficacy of local steroid injection is supported by strong evidence of efficacy 8 weeks after injection. However, the long-term benefit is still being debated.

激素注射或腕骨夹板治疗首次腕管综合症？

腕管综合症是手部疼痛，感觉障碍和无力的常见原因，影响日常活动和生活质量。这是进行医疗咨询的常见原因，多达40％的患者仅在初级保健中接受治疗。治疗目标是缓解症状，改善功能并防止疾病发展为神经损伤。对于大多数初次腕管综合症患者而言，构成标准护理的两种治疗方法是夜间夹板和局部类固醇注射。在一项美国国家数据库研究（2009-13年）的大样本中，腕管综合征的患者中有71％接受了立即手术而无需事先注射类固醇。关于夜间夹板治疗腕管综合症的有效性的证据薄弱，最佳治疗持续时间尚不清楚，并且获益通常很小。^， 在安慰剂对照试验中尚未评估夜间夹板的功效，并且在注射后8周有力的证据证明了局部类固醇注射的功效。但是，长期利益仍在争论中。
