The authors report the cases of three patients with L-5 radiculopathy caused by extraforaminal entrapment of the L-5 spinal nerve at the lumbosacral tunnel; this structure comprises the lumbosacral ligament, the sacral ala, and the L-5 and S-1 vertebral bodies. All three patients suffered severe leg pain and neurological deficits compatible with L-5 radiculopathy. Decompressive surgery involved the microendoscopic partial resection of the sacral ala along the L-5 spinal nerve. All patients experienced immediate pain relief postoperatively. Microendoscopic partial resection of the sacral ala is an effective and minimally invasive surgical option for patients with extraforaminal entrapment of the L-5 spinal nerve.
作者报告了3例因L5脊神经在腰骶管椎间孔外受压导致L5神经根病的病例；该结构由腰骶韧带、骶骨翼以及L5和S1椎体组成。所有3例患者均遭受严重腿痛及与L5神经根病相符的神经功能缺损。减压手术包括沿L5脊神经对骶骨翼进行显微内镜下部分切除。所有患者术后疼痛均立即缓解。对于L5脊神经椎间孔外受压的患者，骶骨翼显微内镜下部分切除是一种有效且微创的手术选择。
