Two cases of lumbar canal stenosis with severe muscular atrophy were reported. The chief complaints of the patients were gait disturbance and weakness of the feet. Myelographic findings showed a high degree of block at the L3-4 and L4-5 interspaces. Laminectomy was carried out and it was observed that hypertrophic and clover-leaf formed neural arches, thichened ligamentum flavum and posterior bulging of the degenerated discs constituted the factors of the stenosis. A half year after surgery, slight symptomatic relief was achieved in both cases. But it was suggested that in the first case, a 51 year-old man, there was the possibility of co-existence of the atypical Charcot-Marie Tooth disease with lumbar canal stenosis on account of the postoperative course and elevation of serum levels of creatine phosphokinase.
