C3-4頸髄症の臨床的検討

抄録

  The purpose of this study is to elucidate the characteristics of C3-4 level cervical spondylotic myelopathy. This study included 11 patients, 9 men and 2 women. Mean age at admission was 75.4 years. Clinically, all of the patients had clumsy hands and gait disturbance. There was also wooziness in 7 cases. This unusual symptom may contribute to late diagnosis. Radiologically, hypermobility at the C3-4 segment compensating for decreased mobility at lower segments may induce hypertrophy of the ligamentum flavum and disc bulging. This may be related to the occurrence of C3-4 level myelopathy.
