[New aspects of post-traumatic dystrophy syndrome?].

Posttraumatic dystrophy (PTD) is a syndrome that involves both neurological symptoms and microvascular abnormalities. A total of 44 consecutive patients seen for the first time with PTD were investigated. In 42 patients X-rays were taken: of the cervical spine in the case of PTD of the hand, and of the cervical, thoracic, and lumbar spine in the case of PTD of the foot. Two patients refused this investigation. In all 44 patients microvascular functions were investigated by means of transcutaneous oximetry, laser Doppler flow metering and capillary microscopy. In 34 of 42 patients radiographical disturbances of the vertebral column were noted, 19 of them on the same side as the affected extremity. Patients with a sensation of warmth in the affected extremity during the investigations exhibited a different microvascular behaviour than patients with a cold feeling. Both groups had different microvascular outcomes from healthy volunteers.

Effects and side effects of a percutaneous thermal lesion of the dorsal root ganglion in patients with cervical pain syndrome.

Twenty consecutive patients with intractable chronic pain in the cervical region were treated with a radiofrequency lesion of the dorsal root ganglion on level C4, C5 or C6. Electromyography (EMG) and sensory evoked potentials (SEP) were recorded before and 3 weeks after the radiofrequency lesion. Side effects were studied 3 weeks, 6 weeks and 3 months after the procedure. Pain scores were evaluated on Numeric Rating Scales (NRS) before and 6 weeks after treatment. The patient was interviewed 3, 6 and 9 months after the radiofrequency lesion. The most common side effect was burning pain in the dermatome of the treated nerve root. Hyposensibility in the dermatome was noticed in 35% of patients. Except in 1 patient, these side effects had disappeared 6 weeks after treatment. The EMG showed no signs of denervation. One SEP recording remained abnormal after treatment. There was initial pain relief in 75% of patients after 3 months and in 50% of the patients after 6 months. In conclusion, this study did not reveal any signs of motor denervation after a percutaneous partial rhizotomy. There were no long-term signs of deafferentation. Initial pain relief was found in 75% of patients, but there was a marked tendency for pain to recur in a period from 3 to 9 months after treatment.

Percutaneous radiofrequency Gasserian ganglion coagulation in the treatment of trigeminal neuralgia.

Fifty-three patients with trigeminal neuralgia were treated with percutaneous radiofrequency Gasserian ganglion coagulation. An individually adjusted degree of coagulation was applied. The procedure was successful in 45 patients (85%). The median follow-up was two years; only two of the remaining 45 patients had relapse of symptoms. Four patients experienced side effects consisting of troublesome facial dysaesthesia. Our data indicate that percutaneous radiofrequency coagulation of the Gasserian ganglion is a safe and reliable procedure in the treatment of medication resistant trigeminal neuralgia.
