Object

The object of this investigation was to conduct a morphometric study in cadavers to determine anatomical structures, their relationships, and their morphometry for subaxial cervical spondylectomy.

Methods

Forty sides of 20 cadavers were used for this study. Dissections were performed in 2 stages (anteriorly and posteriorly). Twenty-one morphometric measurements were performed for both sides of the C3–6 vertebrae. Data were analyzed statistically.

Results

Morphometry of the laminas, tuberculum posterius, pedicle, corpus, foramen transversarium, and processus costalis were measured.

Conclusions

Detailed quantitative anatomical knowledge for operations requiring wide dissection and resection, such as cervical spondylectomy, lowers the morbidity rate.

✓Local administration of bleomycin for the treatment of craniopharyngioma is occasionally associated with serious regional complications. The authors report a case of a delayed neurotoxic complication associated with bleomycin treatment in a patient who had previously undergone radiosurgery. A 14-year-old boy presented with a cyst recurrence of mixed-type craniopharyngioma. An Ommaya device was placed in the thin-walled cyst, and after confirmation that the device was watertight, the patient received a total dose of 75 mg bleomycin intratumorally during a 5-week period. Six weeks after the final drug administration, the patient experienced complex partial epileptic seizures; a few days later sudden right temporal hemianopia developed. Within 5 days the patient became totally blind in his right eye, and the condition did not respond to corticosteroid therapy. Although drug-related toxic complications occur commonly during the course of intracavitary bleomycin treatment, they may also be encountered during the follow-up period. The reason for this delayed complication could have been previous radiotherapy or hypersensitivity of the tumor capsule to the drug.

This study was designed to evaluate the efficacy of decompressive surgery for degenerative lumbar spinal stenosis (LSS) on a functional and clinical basis.

Methods

A prospective analysis and follow-up of 125 consecutive patients with degenerative LSS between 2000 and 2006 were performed. All patients underwent surgery for lumbar stenosis. Functional evaluations of the patients were performed using a treadmill, the visual analog scale, and the Oswestry Disability Questionnaire (ODQ). These parameters were recorded before surgery and the 3rd month and 1st and 2nd years after treatment. The first symptom time (FST), maximal walking duration (MWD), and thecal sac cross-sectional area (CSA) before and after surgery were also recorded. Statistical relations between variables were calculated.

Results

As patient ages increased, the CSA of the thecal sac decreased. Decompressive surgery reached the target according to the difference between the preoperative and postoperative thecal sac CSA. A correlation between the CSA of the thecal sac and FST, and between the CSA of the thecal sac and MWD could not be established. There was a significant correlation between the FST and MWD, and a negative correlation could be established between the MWD and the ODQ score. Surgery led to significant decreases in the ODQ score. Maximal improvement was observed in the 3rd month after decompressive surgery.

Conclusions

The treatment for LSS should be decided using functional criteria; radiological criteria may not correlate with the severity of the disease. Improvements following lumbar decompression surgery continued within 1 year of treatment according to the ODQ and did not change significantly thereafter.
