Patients with the distal type of cervical spondylotic amyotrophy tend to have impingement of the anterior horn of the spinal cord, according to study findings.
Researchers retrospectively reviewed data for 17 patients with the distal type of cervical spondylotic amyotrophy (CSA) who underwent surgical treatment. MRI or CT myelography was used to assess spinal cord or nerve root impingement, and surgical outcomes were evaluated.
According to the researchers, the duration of preoperative symptoms was an average of 11.8 months. Fourteen patients were found to have impingement of the anterior horn of the spinal cord, and three patients were found to have impingement of both the anterior horn and nerve root.
Treatment with laminoplasty was utilized in 12 patients, whereas anterior cervical discectomy and fusion was performed in three patients and posterior spinal fixation was performed in two patients.
The surgical results were excellent in seven cases, good in two cases, fair in eight cases and poor in none of the cases, with a mean manual muscle testing grade of 2.4 preoperatively and 3.4 at the most recent follow-up evaluation, according to the researchers.
