Inverted-hook occipital clamp system in occipitocervical fixation. Technical note.

The authors describe an occipitocervical fixation procedure in which they use inverted occipital hooks inserted through a burr hole drilled in the squamous part of the occipital bone. Fifteen patients with unstable lesions of the occipitocervical junction underwent occipitocervical internal fixation. The mean follow-up period was 21 months (range 2-63 months). No implant failed, and postoperative immobilization was not required. The placement of a posterior occipitocervical graft (for which fusion is uncertain) can be avoided in certain conditions.

Arachnoiditis ossificans of the cauda equina. Case report and review of the literature.

The authors describe a case of arachnoiditis ossificans (AO) of the cauda equina. The lesion is a rare pathological entity usually confined to the thoracic and high lumbar regions that can cause progressive spinal cord and cauda equina compression, inducing severe neurological deterioration. The authors analyze the clinical symptoms, radiological features, histological data, and treatment options relating to this case and 13 others described in the literature; additionally, they consider the possible mechanisms responsible for ossification of the leptomeninges. Although clustered arachnoidal cells are usually implicated in its pathogenesis, an environment induced by arachnoiditis and disturbed cerebrospinal fluid flow appears to be a more important factor. A therapeutic strategy is proposed for AO for which no effective treatment currently exists.
