Abstract

Background: Thoracic disc herniation accounts for only 0.15 to 1.8% of all spinal herniated discs. Usually present between the third and sixth decades with a female predilection. Objectives: To describe the surgical outcome and prognostic factors of post-decompression without fixation in CTDs. Patient and methods: from October 2016 to July 2019, a series of 9 patients with a CTD with demographic data, presentation, imaging findings, operative details, degree of spinal stenosis, duration of symptoms `and outcomes using ASIA scale or mFAC.
Results: All patients presented with at least one sign of myelopathy. Simple laminectomy was performed, and follow-up was in 1st week and 6th month. In 1st week, according to ASIA grade improved in 4 (44, 4%), stationary in 3 (33.3%), deteriorated in 2 (22.2%) patients. According to ambulation, non-ambulatory in 3 (33.3%) and independent in 5 (66.6%) patients. In 6th month, according to ASIA grade improved in 5 (62.5%), stationary in 2 (25%), deteriorated in1 (12.5%) patient. According to ambulation, non-ambulatory in 1 (12.5%), independent in 3 (37.5%) and walker in 4 (50%) patients, one patient is missed in the 6th-month follow-up. Prognostic factors affected the surgical outcome, including the degree of spinal canal stenosis and duration of symptoms.
Conclusions: Posterior decompression without instrumentation allowed us to decompress the compromised spinal cord. Results overall are good with the majority of patients improving at least 1 ASIA scale or mFAC. Better outcomes were affected with less degree of spinal stenosis and less duration of symptoms
