The purpose of this study was to assess recovery and clinical outcome in patients with primary or secondary radial nerve palsy following humeral shaft fracture.
We retrospectively assessed 102 patients (45 female and 57 male) with humeral shaft fracture and concomitant radial nerve palsy, who were followed up for 12 months. Patients were divided into two groups with primary or secondary radial nerve palsy depending on the onset. Muscle function was measured according to Daniels classification and degree of nerve damage was assessed by the Sunderland classification.
The average time for onset of recovery after primary RNP was 10.5 ± 3.31 weeks, in the case of secondary RNP it was 8.9 ± 7.98 weeks (p < 0.05). Full recovery or significant improvement was achieved with average of 26.7 ± 8.86 weeks and 23.9 ± 6.04 weeks respectively (p < 0.05). Trauma mechanism and type of treatment had no significant influence on time of onset of recovery or time to full recovery (p < 0.904).
Secondary RNP shows tendency for earlier recovery and is more commonly associated with ORIF.
本研究旨在评估肱骨干骨折后原发性或继发性桡神经麻痹患者的恢复情况及临床结局。
我们回顾性评估了102例肱骨干骨折合并桡神经麻痹的患者（45例女性，57例男性），随访12个月。根据发病情况将患者分为原发性或继发性桡神经麻痹两组。根据丹尼尔斯分类法测量肌肉功能，并通过桑德兰分类法评估神经损伤程度。
原发性桡神经麻痹恢复开始的平均时间为10.5±3.31周，继发性桡神经麻痹为8.9±7.98周（p<0.05）。完全恢复或显著改善分别平均需要26.7±8.86周和23.9±6.04周（p<0.05）。创伤机制和治疗方式对恢复开始时间或完全恢复时间无显著影响（p<0.904）。
继发性桡神经麻痹显示出恢复较早的趋势，且更常与切开复位内固定术相关。
