STUDY DESIGN
Case report.
OBJECTIVE
To report an unusual case of vastus lateralis muscle rupture not accompanied by any history of major trauma or the presence of a risk factor in a patient with spinal stenosis. Isolated vastus lateralis muscle rupture without an obvious cause is very rare. Localized pain and claudication are the most common symptoms and can be misdiagnosed as lumbar radiculopathy.
METHODS
A 70-year-old patient presented with right lower extremity and back pain, diagnosed as spinal stenosis. He was initially treated with caudal epidural block and transforaminal epidural block, which resulted in nearly complete relief of his symptoms. However, he subsequently experienced a pain that was no longer responsive to treatment. The ultrasonographic exam revealed a partial tear of the right vastus lateralis muscle.
RESULT
Injection of local anesthetics relieved the patient's symptoms. At 1-month follow-up, he remained pain-free.
CONCLUSIONS
In patients with lower back and leg pain, physicians should consider non-spinal conditions that can cause signs and symptoms mimicking lumbar radiculopathy.
研究设计
病例报告。
目的
报告一例椎管狭窄症患者在无重大创伤史或无任何危险因素的情况下发生股外侧肌巨大撕裂的罕见病例。无明显病因的孤立性股外侧肌撕裂非常罕见。局部疼痛和跛行是最常见的症状，容易误诊为腰椎神经根病。
方法
一名 70 岁男性患者因右下肢和背部疼痛就诊，诊断为椎管狭窄症。他最初接受了骶管硬膜外阻滞和经椎间孔硬膜外阻滞治疗，症状几乎完全缓解。然而，他随后出现了一种治疗无效的疼痛。超声检查显示右侧股外侧肌部分撕裂。
结果
局部麻醉注射缓解了患者的症状。在 1 个月的随访中，他无疼痛。
结论
对于出现腰背和腿部疼痛的患者，医生应考虑可能导致类似腰椎神经根病的体征和症状的非脊柱疾病。
