Abstract

fetched live from OpenAlex

OBJECTIVES: To evaluate a new surgical treatment consisting of neurolysis of the great occipital nerve and section of the inferior oblique muscle. DESIGN.: A retrospective study of 10 patients operated for greater occipital neuralgia. SUMMARY AND BACKGROUND DATA: This technique is based on a previous anatomic cadaver study. The greater occipital nerve is stretched by the inferior oblique muscle of the head during flexion of the cervical spine. Sectioning this muscle relaxes the greater occipital nerve. With this procedure, the authors systematically associate release of the nerve down to the inferior edge of the inferior oblique muscle. METHODS: A retrospective study was conducted of 10 patients operated on from January 1998 to December 1999 for greater occipital neuralgia. All the patients had pain exacerbated by flexion of the cervical spine. The average age of the patients was 62 years. The mean follow-up of the series was 37 months. The results of the treatment were assessed according to three criteria: 1) degree of pain on a Visual Analogue Scale before surgery, at 3 months, and at last follow-up; 2) consumption of analgesics before surgery and at follow-up; and 3) the degree of patient satisfaction at follow-up. RESULTS: In three cases, anatomic anomalies were found. One patient had hypertrophy of the venous plexus around C2. In another, the nerve penetrated the inferior oblique muscle. The third had degenerative C1-C2 osteoarthritis requiring associated C1-C2 arthrodesis. The mean Visual Analogue Scale score was 80/100 before surgery and 20/100 at last follow-up. Consumption of analgesics decreased in all patients. Seven of the 10 patients were very satisfied or satisfied with the operation. CONCLUSION: This surgical technique gives good results on greater occipital neuralgia if patients are well chosen. Nerve release is justified by the frequency of associated anatomic abnormalities.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
