Surgical approach to anterior compression in the upper thoracic spine

Efficacy analysis of one-stage posterior-only surgical treatment for thoracic spinal tuberculosis in the T4-6 segments with minimum 5-year follow-up

In recent years, with the in-depth research on spinal tuberculosis, posterior surgery alone has been praised highly by more and more surgeons due to the better correction of kyphosis, better maintenance of spinal physiological curvature, smaller surgical trauma and fewer surgical complications. However, there is currently lack of relevant reports about the efficacy of posterior surgery alone in the treatment of tuberculosis in the T4–6 segments. This study aimed to evaluate the clinical study efficacy and feasibility of one-stage posterior-only surgical treatment for thoracic spinal tuberculosis in the T4–6 segments. 67 patients with tuberculosis in T4–6 segments who underwent one-stage posterior-only surgery were included in this study. The clinical efficacy was evaluated using statistical analysis based on the data about erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Oswestry Dability Index (ODI) score, Visual Analogue Scale (VAS) score and Cobb angle before surgery, after surgery and at the last follow-up. All patients completed fusion during the follow-up period of 6–9 months. ESR and CRP were returned to normal for all patients at 6 months follow-up. In the meanwhile, among the 27 patients combined with neurological impairment, neurological functions of 22 cases (81.48%) recovered completely at the last follow-up (P < 0.05). Cobb angle of the kyphosis was improved from preoperative 34.8 ± 10.9° to postoperative 9.6 ± 2.8°, maintaining at 11.3 ± 3.2° at the last follow-up, The ODI and VAS scores were improved by 77.10% and 81.70%, respectively. This 5-year follow-up study shows that better clinical efficacy can be achieved for tuberculosis in T4–6 segments using one-stage posterior-only approach by costotransverse debridement in combination with bone graft and internal fixation. The posterior surgical method cannot only effectively accomplish debridement, obtain satisfactory clinical results, but also well correct kyphotic deformity and maintain it.

Investigation of Radiologic Landmarks Used to Decide the Appropriate Surgical Approach for Upper Thoracic Ventral Degenerative Disorders

BACKGROUND

Ventral lesions of upper thoracic spinal cord due to degenerative diseases are rare and often have poor operative outcomes. Anterior decompression of the lesion is difficult because of the local anatomy. This retrospective study aimed to evaluate reproducible anatomic measurements for selecting the best surgical approach for anterior decompression of ventral lesions of upper thoracic spinal cord.

METHODS

Cases of anterior decompression of ventral lesions of upper thoracic spinal cord due to degenerative diseases at our institution from 2004 to 2015 were assessed. Several lines were drawn on magnetic resonance imaging and computed tomography scans of midsagittal sections of the upper thoracic spine to evaluate the most optimal approach for treating upper thoracic lesions. A line from the suprasternal notch to the vertebral body (suprasternal notch to vertebral body [SV] line) was accepted as baseline.

RESULTS

The caudal edge of the lesion was above the SV line in 10 cases, each of which was treated via an anterior approach without sternotomy. The caudal edge was below the SV line in 7 cases, 5 of which underwent surgery with the sternum-splitting or transthoracic approach. The other 2 lesions were approached via an obliquely deviated route without sternotomy. The SV line sometimes changed with patients' posture alterations.

CONCLUSIONS

The SV line, a useful landmark for upper thoracic lesions, is not sufficiently reliable because it changes according to the patient's posture. By leaning in the direction of the surgical microscope, more caudal upper thoracic lesions can be reached than when using the SV line as a surgical landmark.

Surgical approaches to upper thoracic Pott's disease with spinal instability during childhood: two cases

PURPOSE

Tuberculosis is a common disease worldwide that is caused by Mycobacterium tuberculosis. Tuberculosis is primarily a pulmonary disease, but extrapulmonary manifestations are not uncommon, especially in children and adolescents.

METHODS

We present two pediatric patients who underwent surgery in our clinic for Pott's disease in the upper thoracic region. The patients were investigated to describe their age, complaints, neurological examination results, disease location, surgical procedure, and complications.

RESULTS

The patients were 2 and 14 years old and exhibited disease located in the upper thoracic region (T2-T3 and T1-T2). Both patients displayed severe neurological deficits (Frankel B and C). The kyphotic angles were 82.2° and 43.2°. The patients were stabilized by applying fusion using transpedicular screws via a posterior approach. They also underwent anti-tuberculosis treatment for approximately 1 year. One year later, neither patient exhibited any neurological deficit, and their kyphotic angles were measured as 11° and 1°, respectively.

CONCLUSIONS

The recommended treatment approach for unstable cases of Pott's disease located in the upper thoracic region who exhibit neurological deficit and severe kyphotic angling or the development of kyphosis on the thoracic vertebrae is surgical. Decompression, stabilization, and fusion and kyphotic correction can be safely performed via a posterior approach. One of the present cases is the youngest patient described in the literature to undergo transpedicular surgery as a result of Pott's disease. Our other case is the first described in the literature who developed ptosis as a result of tuberculosis and underwent a procedure via posterior transpedicular screw.

Transthoracic approach for lesions involving the anterior dorsal spine: A multidisciplinary approach with good outcomes

Introduction:

Anterior approach provides excellent visualization and access to the anterior thoracic spine. It may be used alone, in combination with a posterior midline approach or in a staged or sequential fashion.

Aims:

To analyse our institutional experience in transthoracic approaches and to determine the safety and benefit of this approach in our patient series.

Materials and Methods:

A total of 16 patients were operated for varying lesions of body of dorsal vertebra by the transthoracic approach. The study was for a period of 5 years from January 2011 to December 2015. Patients age ranged from 25 to 61 years with an average of 36.4 yrs. There were 7 males and 9 females. In our series 9 patients had Kochs spine, 4 patients were traumatic fracture spine and 3 had neoplastic lesion. Majority of patients had multiple symptoms with backache being present in all patients.

Results:

There was one post operative mortality which was unrelated to surgery. One patient had post operative delayed kyphosis. Remaining patients improved in their symptoms following surgery.

Conclusion:

With careful coordination by thoracic surgeons, neurospinal surgeons and anaesthetists, the anterior spine approach for dorsal spine is safe and effective. Adequate preoperative evaluation should stratify the risk and institute measures to reduce it. Accurate surgical planning and careful surgical technique are the key to yield a good outcome and to reduce the risk of complications.

One-stage surgical treatment for upper thoracic spinal tuberculosis by internal fixation, debridement, and combined interbody and posterior fusion via posterior-only approach

PURPOSE

To investigate the clinical efficacy and feasibility of one-stage surgical treatment for upper thoracic spinal tuberculosis by internal fixation, debridement, and combined interbody and posterior fusion via a posterior-only approach.

METHODS

Fourteen patients (eight males, six females) with upper thoracic tuberculosis whose lesions were confined to two adjacent segments were admitted to our hospital. Their ages ranged from 23 to 72 years (average, 50 years). The American Spinal Injury Association (ASIA) impairment scale was used to assess neurological function. ASIA classification showed that preoperatively, one patient was grade A, two patients were grade B, eight patients were grade C, and three patients were grade D. All patients were treated with one-stage surgical treatment by internal fixation, debridement, and combined interbody and posterior fusion via a posterior-only approach. Patients were evaluated preoperatively and postoperatively by measurement of thoracic kyphotic angles using Cobb angle evaluation, determination of erythrocyte sedimentation rate (ESR), evaluation of ASIA impairment scale, and radiological examination.

RESULTS

Operation time ranged from 70 to 135 min, (average, 110 min). Intraoperative blood loss ranged from 200 to 950 mL (average, 450 mL). All patients were followed up for 22 to 48 months postoperatively (average, 31.5 months). No sinus tract formation, cerebrospinal meningitis, or recurrence of tuberculosis occurred. All patients had significant postoperative improvement in ASIA classification scores. The thoracic kyphotic angles were significantly decreased to 12°-26° postoperatively, and at final follow-up were 13°-28°. The ESR recovered to normal within 6 months postoperatively in all patients. Bone fusion was achieved within 3-8 months (average, 5.5 months).

CONCLUSIONS

One-stage surgical treatment for upper thoracic spinal tuberculosis by internal fixation, debridement, and combined interbody and posterior fusion via a posterior-only approach can be an effective and feasible treatment method.
