Common peroneal nerve block for sciatica.

The effectiveness of common peroneal nerve block for lumbar disc herniation was evaluated in a double blind study. Common peroneal nerve block was performed near the fibular head in nine patients using 2% lidocaine and in 10 patients using saline. The average pain scale score decreased from 3.1 to 0.6 in the lidocaine group, whereas it decreased from 3.0 to 2.6 in the placebo group. The average result in the straight leg raising test increased from 61 degrees to 84 degrees in the lidocaine group, but from 44 degrees to 50 degrees in the placebo group. Lower leg pain lessened more in the lidocaine group than in the placebo group. The finding that lower leg pain disappeared or decreased with a lidocaine block at a site far distal to the lumbar lesion suggests that impulses that are transmitted distal to the lesion may be important for the generation of sciatic radicular pain.

[Quality assurance of back surgery. A follow-up of 350 patients treated for sciatica by means of survival analysis].

350 patients underwent a follow-up 2-16 years after back surgery. The aim was to find quality indicators, such as frequency of complications, recurrences and reoperation, in addition to establishing postoperative status and patient satisfaction. The complication rate was 9.7%. Most complications were not serious, and there was no mortality. We found a cumulative recurrency rate of 18% and a cumulative reoperation rate of 12%. Women had significantly better long-term results than men, psychosocial problems being a strong negative predictor. Questionnaires revealed that 76% of the patients were satisfied, whereas 22% were not. Postoperatively, 59% reported a persistent, but usually slight back problem.

Caudascopic experiences and a new patho-anatomic concept for treatment of sciatica.

In order to investigate the potential of an exclusively endoscopic extradural approach as an alternative to open discectomy, epidural endoscopy was performed in 5 cadavers. This did not produce satisfactory images of the epidural space. Intradural endoscopy (caudascopy) was performed, to show whether additional anatomical factors might explain a radicular syndrome supplementary to or without a disc herniation. Caudascopy allowed excellent images of the cauda equina, nerve roots, and the entrance of the lumbar nerve root sheaths. A Fogerty balloon positioned in the intervertebral foramen was used to simulate disc herniation. The impact of this simulation on the intradural endoscopic image was observed to be minimal. A dural fold was identified at the entrance of the nerve root sheath. It is proposed as a factor contributing to the mechanical involvement of lumbosacral nerve roots. Pressure measurements in the intradural nerve root sheath support this preliminary finding. An endoscopical management of this potential patho-anatomy of the nerve root is suggested.
