英文摘要:

Background Various surgical approaches have been successfully used in the treatment of thoracolumbar disc herniation (TLDH). Although the anterior transthoracic approach has a reputation for better visualization than the posterolateral and lateral approaches, it involves the manipulation of the thoracic and pulmonary structures. Thus, this approach is technically demanding and prone to compromising the respiratory system. An ideal approach would involve adequate visualization and be accomplished through the posterior midline approach that is familiar to spine surgeons. The objective of this retrospective preliminary clinical study was to introduce a new surgical procedure, circumspinal decompression through a single posterior incision, for the treatment of TLDH (T10/11-L1/2) and to evaluate the surgical outcome of this procedure by comparing it to the conventional anterior transthoracic approach.

Methods In this study, 15 patients (10 males, 5 females; mean age 51 years) with symptomatic TLDH underwent the circumspinal decompression through a single posterior incision procedure between January 2008 and December 2009. Altogether, 17 herniated discs were excised, with 2 discs at T10/11, 4 discs at T11/12, 5 discs at T12/L1 and 6 discs at L1/2. Of these patients, 13 were followed up with a mean follow-up period of 23.5 months. Clinical outcomes, including operative time, blood loss, perioperative complications, postoperative time of hospitalization, neurologic status improvement, back pain and correction of local kyphosis, were investigated by comparing these data with the results from patients who underwent the anterior transthoracic approach for TLDH during the same period. The patients′ neurologic status was evaluated by a modified Japanese Orthopedic Association (JOA) scoring system of 11 points. Neurologic status improvement after the surgery was assessed by calculating the recovery rate, which was equal to the (postoperative JOA score preoperative JOA score)/(11-preoperative JOA score)x100%. The rates of patients who improved at the final follow-up were also assessed.

Results The mean operative time was 183 minutes, the mean blood loss was 1067 ml, and the mean postoperative hospitalization time was 8.4 days. Three patients suffered perioperative complications, but none of these complications involved the respiratory system. Local kyphotic angles at the fusion levels were reduced. Of the 13 patients that were followed up, 12 improved at the final follow-up, with a mean recovery rate of 52.8%. Patients who underwent the circumspinal decompression procedure showed a higher percentage of improvement at the final follow-up, a higher degree of local kyphosis correction and a lower percentage of complications (especially respiratory complications) compared to patients who underwent the anterior transthoracic decompression procedure.

Conclusions The circumspinal decompression through a single posterior incision procedure is an effective and safe technique that is comparable to anterior tranthoracic approach for the surgical treatment of TLDH patients. It could be an attractive choice in certain circumstances. Chin Med J 2011;124(23):3852-3857
