SPINAL-CORD STIMULATION IN VIBRATION WHITE FINGER

The authors report a case of vibration white finger syndrome in a 51-y ear old male, pneumatic drill worker: The patient complained of severe pain in the I, II, III and IV right fingers related to acral ischemic lesions. Dried skin with desquamation, tingling, paraesthesia and los s of sensation were present in both hands. Several arterial obstructio ns on forearm, hand and fingers were evident bilaterally at the angiog raphy. Medical treatment, including administration of calcium-channel blockers, pentoxifylline and intravenous prostaglandin therapy was uns uccessful. Under local anaesthesia an epidural spinal cord cervical el ectrode was implanted to control pain and ameliorate local microcircul atory conditions. The clinical result was excellent with the disappear ance of symptoms and healing of acral lesions in a few weeks. Epidural spinal cord electrical stimulation represents an excellent technique for treatment in secondary Raynaud phenomenon related to vibration whi te finger syndrome.
