目的:探讨青年上肢远端肌萎缩的临床特征。方法:回顾性分析2例该病患者的临床资料。结果与结论:其中1例为21岁男性,主要表现为右手指伸直困难,查体见手和上肢远端肌群萎缩,右上肢远端肌力4级,右手背侧尺神经支配区浅感觉减退。肌电图:右尺神经损伤;颈椎MRI:颈5～6椎体后凸明显,颈髓受压。另1例为35岁男性,主要表现为双上肢萎缩,查体:双上肢远端肌力4级,EMG:左侧尺神经MCV减慢,左侧F波不出波,左侧大小鱼际肌肌电图示神经源性损害;颈椎MRI:C5/6椎间盘突出,颈椎退变;颈椎过伸过屈位:C5/6、C 6/7椎间盘膨出,C5/6水平椎管过屈位狭窄,C5/7椎体水平脊髓变细。
Objective: To investigate the clinical features of young distal atrophy of upper limbs. Methods: The clinical data of 2 patients with this disease were retrospectively analyzed. RESULTS AND CONCLUSION: One case of 21-year-old male mainly showed difficulty in straightening the right finger. Atrophy of the distal hand and upper extremity musculature was seen in the examination. The distal right upper extremity muscle strength was grade 4 and the right dorsal ulnar nerve innervation area was shallow Feeling diminished. EMG: Right ulnar nerve injury; Cervical MRI: Cervical 5-6 kyphosis obvious, cervical compression. Another case of 35-year-old male, mainly manifested as double upper extremity atrophy, physical examination: distal upper extremity muscle strength 4, EMG: left ulnar nerve MCV slowed, the left F wave wave, the left size EMG showed neurogenic lesions; Cervical MRI: C5 / 6 disc herniation, cervical degeneration; Cervical hyperextension and flexion: C5 / 6, C 6/7 disc herniation, C5 / 6 level of spinal flexion Stenosis, C5 / 7 vertebral level spinal cord thinning.
