Surgical management of consecutive multisegment thoracic and lumbar tuberculosis: anterior-only approach vs. posterior-only approach

Anterior tuberculosis lesion debridement and bone grafting combined with short-segment internal fixation in the treatment of thoracolumbar tuberculosis

STUDY DESIGN

This was a retrospective study.

OBJECTIVE

To retrospectively analyze the safety and efficacy of anterior lesion debridement and bone grafting combined with short-segment internal fixation for the treatment of patients with thoracolumbar tuberculosis. There is currently no unified standard in the academic community for surgical treatment of spinal tuberculosis. This study proposes a new surgical approach for specific thoracolumbar tuberculosis.

METHODS

Patients (n = 65) who underwent anterior lesion debridement and bone grafting combined with short-segment internal fixation at our institution between January 2011 and January 2021 were included in this study. The patients were followed up for at least 2 years. During each follow-up, patients were graded using the American Spinal Injury Association (ASIA) neurologic deficit grading system, and postoperative conditions were evaluated using the Oswestry Disability Index (ODI) and pain visual analog scale (VAS).

RESULTS

All patients successfully completed the surgery without serious complications.Four patients had unstable vital signs during the operation, 3 patients had a water-electrolyte imbalance in the postoperative period, 5 patients had transient neurological symptoms in the postoperative period, 1 patient had cerebrospinal fluid leakage after the operation, 1 patient had a transient nerve injury, and 1 patient had delayed healing. The patient with recurrence was treated regularly with quadruple antituberculosis drugs for three months after surgery and then maintained with two oral antituberculosis drugs for the following period. The CT examination was repeated half a year later, and all the indexes showed that the prognosis was good. The patients' mean postoperative VAS and ODI scores were significantly better than the preoperative scores.

CONCLUSION

Anterior tuberculosis lesion debridement and bone grafting combined with short-segment internal fixation in the treatment of thoracolumbar tuberculosis has certain advantages over other Surgical Procedures, and can achieve corresponding clinical results.

Original Uniportal Bichannel and Dual-Media Spinal Endoscopy System Assists Elderly Patients with Thoracolumbar Kyphosis Associated with Osteoporosis: Technical Note and Preliminary Clinical Results

BACKGROUND

The uniportal bichannel and dual-media spinal endoscopy (UBD) system is an original endoscopic system developed by the authors. This technical note describes a single-center case series of elderly patients with thoracolumbar kyphosis (TLK) with osteoporosis treated with the assistance of the UBD system.

METHODS

This article presents a retrospective case series including 4 patients with TLK with osteoporosis treated with assistance of the UBD system. Demographic, clinical, imaging, and procedure-related data are reported.

RESULTS

All 4 patients achieved satisfactory correction of TLK. The regional kyphosis angle and TLK improved significantly in the patients, correcting from 24.73 ± 6.51° to 5.46 ± 2.16° (P < 0.001) and 29.28 ± 4.02° to 6.33 ± 3.13° (P < 0.001). The patients showed an improvement in visual analog scale and Oswestry Disability Index scores postoperatively (P < 0.001). No complications were observed.

CONCLUSIONS

This study suggests that use of the UBD system to assist in treatment of elderly patients with rigid TLK with osteoporosis is a safe and effective approach.

Modified costotransverse approach combined with autologous iliac bone graft fusion and internal fixation in thoracic tuberculosis

BACKGROUND

Due to the complexity of the thoracic spine's surrounding structures, thoracic tuberculosis surgery is challenging to perform, with difficult exposure, complex operations, numerous complications, and often unsatisfactory prognoses. Currently, it is believed that the posterior approach alone is superior to both the anterior and the combined anterior-posterior surgical methods in correcting spinal kyphosis and maintaining spinal stability. The posterior approach encompasses the transpedicular approach, costotransverse approach, and lateral thoracic approach. The aim of this study is to explore the clinical safety and efficacy of a modified costotransverse approach, originally known as 'banana peel preservation surgery,' combined with autogenous iliac bone graft fusion and internal fixation for the treatment of thoracic tuberculosis patients.

METHODS

From July 2016 to December 2024, 23 patients with thoracic tuberculosis were continuously treated using a modified costotransverse approach combined with autogenous iliac bone graft fusion and internal fixation. All patients were treated by the same surgical team, which also used other methods to perform surgeries on other patients (non-participants) during the study period. The group included 12 males and 11 females with an average age of 65.7 years. The duration of surgery, intraoperative blood loss, and visual analog scale (VAS) pain scores, Oswestry disability index (ODI) were recorded and analyzed before surgery, two weeks after surgery, and at the final follow-up. Neurological function was evaluated using the ASIA classification, and radiological results were assessed by measuring changes in the Cobb angle and the bone fusion status of the corrected fusion segment.

RESULTS

The recorded surgical time for 23 patients ranged from 110 to 160 min (mean 133.7 ± 14.3 min), and blood loss ranged from 400 to 650 mL (mean 501.3 ± 74.9 mL). All incisions had healed by the first stage. The fusion time for the transplanted bone was between 3 and 7 months, with a median fusion time of 4 months. There was no loosening or breakage of internal fixation. At the final follow-up, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were both normal. Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores showed significant improvement compared to preoperative values (P < 0.05). By the last follow-up, excluding patients who had normal neurological function previously, the remaining patients showed varying degrees of improvement in neurological function. The distribution of ASIA grades was as follows: 2 cases at grade C, 8 cases at grade D, and 13 cases at grade E. The average follow-up period for patients was 25 months, ranging from 13 to 36 months. Postoperative kyphosis did not progress significantly, and there was no recurrence of tuberculosis. In this group of 23 patients, the ASIA grade distribution at the last follow-up was 1 case at grade D and 22 cases at grade E, with a recovery rate of 90%. All patients received adequate decompression and bone grafting, leading to significant symptom improvement. There were no instances of pleural damage and all patients were free from symptomatic pleural effusion.

CONCLUSIONS

The costotransverse process and the rib head provide sufficient surgical space of 1.1-2.1 cm to serve as decompression and bone graft channels. The preservation of the outer cortex of the rib can effectively prevent the risk of pleural injury and reduce the occurrence of pleural effusion. The modified costotransverse approach, "banana peel preservation surgery(Fig. 1)", combined with autologous iliac bone graft and internal fixation for the treatment of thoracic tuberculosis is a safe and effective surgical method for the treatment of thoracic tuberculosis.

Surgical treatment of spinal tuberculosis: an updated review

Tuberculosis (TB) is a worldwide disease which seriously affects the global public health. Spinal TB is the most common extra-pulmonary TB and may cause vertebral bone destruction, collapse, kyphosis and even paralysis. Anti-TB chemotherapy is considered the cornerstone treatment of spinal TB and surgery is often required for patients with severe kyphosis, impaired neurological function or spinal instability. Debridement of TB lesions, bone grafting and internal fixation are the key procedures of spinal TB surgery. However, the selection of surgical approach, the extent of TB lesion debridement, the choice of bone graft materials, and the method and extent of internal fixation are all remain controversy. The aim of this updated review is to evaluate current literature for advances in management of spinal TB, with particular focus on surgical techniques.

A Comparative Study of Anterior and Posterior Tuberculosis Lesions for the Treatment of Thoracolumbar Tuberculosis disease: A Single Institution Experience in a Major Academic Hospital

Objective

To compare the efficacy of anterior and posterior surgery for thoracolumbar tuberculosis disease.

Methods

Clinical data of 30 patients with thoracolumbar tuberculosis disease undergoing anterior and posterior surgery from January 2021 to December 2023 were collected for a retrospective study. According to the two surgical procedures, patients were divided into two groups: 1) anterior group (n=15) and 2) posterior group (n=15). We compared the two groups regarding age, gender, body mass index, affected segments, past history (cardiovascular and cerebrovascular diseases, respiratory diseases, endocrine system diseases, metabolic diseases, and tuberculosis history), smoking history, drinking history, operation time, postoperative bleeding, postoperative drainage, postoperative time, postoperative complications (dural tear, lower limb intermuscular vein thrombosis, lower limb deep vein thrombosis, sinus infection, postoperative recurrence rate), and waist VAS score before and after surgery, waist ODI score, and JOA score.

Results

The intraoperative blood loss was significantly less in the posterior group than in the anterior group, and the difference was significant (P <0.05); the lumbar VAS score was lower in the posterior group than in the anterior group, and the difference between the two groups was significant (P <0.05). The analysis of the remaining data showed no significant difference between the two groups (P> 0.05), indicating that the efficacy of the two procedures was the same.

Conclusion

In the treatment of thoracolumbar tuberculosis disease, there is no significant difference in the clinical efficacy of anterior surgery and posterior surgery. Intraoperative bleeding in posterior surgery was less than in anterior surgery, but the latter showed a significant improvement in postoperative pain relief. Therefore, spinal surgeons should choose the corresponding surgical treatment according to the actual situation of the patient in order to maximize the efficacy.

Progressive Thoracolumbar Tuberculosis in a Young Male: Diagnostic, Therapeutic, and Surgical Insights

OBJECTIVE

We present the case of a 26-year-old male with severe spinal tuberculosis of the thoracolumbar region. The patient suffered from worsening back pain over five years, initially responding to over-the-counter analgesics. Despite being proposed surgery in 2019, the patient refused the intervention and subsequently experienced significant disease progression.

METHODS

Upon re-presentation in 2022, mild involvement of the T12-L1 vertebrae was recorded by imaging, leading to a percutaneous needle biopsy which confirmed tuberculosis. Despite undergoing anti-tuberculous therapy for one year, the follow-up in 2024 revealed extensive infection from T10 to S1, with large psoas abscesses and a pseudo-tumoral mass of the right thigh. The patient was ultimately submitted to a two-stage surgical intervention: anterior resection and reconstruction of T11-L1 with an expandable cage, followed by posterior stabilization from T8-S1.

RESULTS

Postoperative recovery was uneventful, with significant pain relief and no neurological deficits. The patient was discharged on a continued anti-tuberculous regimen and remains under close surveillance.

CONCLUSIONS

This paper presents details on the challenges of diagnosis and management of severe spinal tuberculosis, with emphasis on the importance of timely intervention and multidisciplinary care.

[Treatment of thoracolumbar tuberculosis with robot-assisted and minimally invasive access via transforaminal expansion approach]

Objective

To investigate the feasibility and effectiveness of robot-assisted posterior minimally invasive access in treatment of thoracolumbar tuberculosis via transforaminal expansion approach.

Methods

A clinical data of 40 patients with thoracolumbar tuberculosis admitted between January 2017 and May 2022 and met the selection criteria was retrospectively analyzed. Among them, 15 cases were treated with robot-assisted and minimally invasive access via transforaminal expansion approach for lesion removal, bone graft, and internal fixation (robotic group), and 25 cases were treated with traditional transforaminal posterior approach for lesion removal and intervertebral bone grafting (traditional group). There was no significant difference in the baseline data between the two groups ( P>0.05) in terms of gender, age, lesion segment, and preoperative American Spinal Injury Association (ASIA) grading, Cobb angle, visual analogue scale (VAS) score, erythrocyte sedimentation rate (ESR), and C reactive protein (CRP). The outcome indicators were recorded and compared between the two groups, including operation time, intraoperative bleeding volume, hospital stay, postoperative bedtime, complications, ESR and CRP before operation and at 1 week after operation, the level of serum albumin at 3 days after operation, VAS score and ASIA grading of neurological function before operation and at 6 months after operation, the implant fusion, fusion time, Cobb angle of the lesion, and the loss of Cobb angle observed by X-ray films and CT. The differences of ESR, CRP, and VAS score (change values) between pre- and post-operation were calculated and compared.

Results

Compared with the traditional group, the operation time and intraoperative bleeding volume in the robotic group were significantly lower and the serum albumin level at 3 days after operation was significantly higher ( P<0.05); the postoperative bedtime and the length of hospital stay were also shorter, but the difference was not significant ( P>0.05). There were 2 cases of poor incision healing in the traditional group, but no complication occurred in the robotic group, and the difference in the incidence of complication between the two groups was not significant ( P>0.05). There were significant differences in the change values of ESR and CRP between the two groups ( P<0.05). All Patients were followed up, and the follow-up time was 12-18 months (mean, 13.0 months) in the traditional group and 12-16 months (mean, 13.0 months) in the robotic group. Imaging review showed that all bone grafts fused, and the difference in fusion time between the two groups was not significant ( P>0.05). The difference in Cobb angle between the pre- and post-operation in the two groups was significant ( P<0.05); and the Cobb angle loss was significant more in the traditional group than in the robotic group ( P<0.05). The VAS scores of the two groups significantly decreased at 6 months after operation when compared with those before operation ( P<0.05); the difference in the change values of VAS scores between the two groups was not significant ( P>0.05). There was no occurrence or aggravation of spinal cord neurological impairment in the two groups after operation. There was a significant difference in ASIA grading between the two groups at 6 months after operation compared to that before operation ( P<0.05), while there was no significant difference between the two groups ( P>0.05).

Conclusion

Compared with traditional posterior open operation, the use of robot-assisted minimally invasive access via transforaminal approach for lesion removal and bone grafting internal fixation in the treatment of thoracolumbar tuberculosis can reduce the operation time and intraoperative bleeding, minimizes surgical trauma, and obtain definite effectiveness.

[Current status of surgical treatment for angular kyphosis in spinal tuberculosis]

Objective

To review current status of surgical treatment for angular kyphosis in spinal tuberculosis and provide reference for clinical treatment.

Methods

The literature on the surgical treatment for angular kyphosis of spinal tuberculosis in recent years was extensively reviewed and summarized from the aspects of surgical indications, surgical contraindications, surgical approach, selection of osteotomy, and perioperative management.

Results

Angular kyphosis of spine is a common complication in patients with spinal tuberculosis. If kyphosis progresses gradually, it is easy to cause neurological damage, deterioration, and delayed paralysis, which requires surgical intervention. At present, surgical approaches for angular kyphosis of the spine include anterior approach, posterior approach, and combined anterior and posterior approaches. Anterior approach can be performed for patients with severe spinal cord compression and small kyphotic Cobb angle. Posterior approach can be used for patients with large kyphotic Cobb angle but not serious neurological impairment. A combined anterior and posterior approaches is an option for spinal canal decompression and orthosis. Osteotomy for kyphotic deformity include Smith-Peterson osteotomy (SPO), pedicle subtraction osteotomy (PSO), vertebral column resection(VCR), vertebral column decancellation (VCD), posterior vertebral column resection (PVCR), deformed complex vertebral osteotomy (DCVO), and Y-shaped osteotomy. SPO and PSO are osteotomy methods with relatively low surgical difficulty and low surgical risks, and can provide 15°-30° angular kyphosis correction effect. VCR or PVCR is a representative method of osteotomy and correction. The kyphosis correction can reach 50° and is suitable for patients with severe angular kyphosis. VCD, DCVO, and Y-shaped osteotomy are emerging surgical techniques in recent years. Compared with VCR, the surgical risks are lower and the treatment effects also improve to varying degrees. Postoperative recovery is also a very important part of the perioperative period and should be taken seriously.

Conclusion

There is no consensus on the choice of surgical treatment for angular kyphosis in spinal tuberculosis. Osteotomy surgery are invasive, which is a problem that colleagues have always been concerned about. It is best to choose a surgical method with less trauma while ensuring the effectiveness.

Clinical outcomes and surgical strategy for spine tuberculosis: a systematic review and meta-analysis

PURPOSE

Spinal tuberculosis (TB) is a slow-developing disease that often causes cord compression, spinal instability, and deformity. Surgery is generally required in cases of refractory disease, severe kyphosis, neurological deficits, or lack of improvement. However, there is a lack of comprehensive evidence in comparing the efficacy of various surgical approaches. The study aims to provide a clearer understanding of the relative effectiveness of the available surgical modalities in the management of spinal TB.

METHODS

This review adhered to the PRISMA statement with searching conducted until 11th April 2023. Inclusion criteria included studies involving surgical procedures for spinal tuberculosis, with relevant clinical outcomes reported. Data extraction involved the collection of information on study and population characteristics, interventions used, relevant clinical outcomes, and reported complications. The risk of bias was evaluated using Cochrane's Risk of Bias in Non-randomized Studies tool.

RESULTS

Searching resulted in 20 cohort studies that analyzed surgical methods for spinal tuberculosis. Eleven studies had low bias and nine studies had moderate bias. The anterior approach was associated with faster perioperative duration [- 2.02 (- 30.71, 26.67), p < 0.00001], less blood loss [- 4242 (- 176.02, 91.18), p < 0.00001], shorter hospitalization [- 0.19 (- 2.39, 2.01), p < 0.00001], better angle correction [1.01 (- 1.82, 3.85), p < 0.00001], and better correction rates [11.36 (- 7.32, 30.04), p < 0.00001] compared to the posterior approach. Regarding neurological function recovery, the anterior and posterior approaches were equally effective, while the posterior approach was associated with a higher incidence of complications. The review also reported on the complications associated with the surgical approaches, and 9 out of 20 studies reported complications. The anterior approach was found to have fewer complications overall.

CONCLUSION

The anterior approach is thought to have fewer complications than both combined and posterior-only approaches, but the variability of the findings indicates that the decision-making process for selecting a surgical approach must consider individual patient and disease characteristics, as well as surgeon training.

Establishment and application of TSDPSO-SVM model combined with multi-dimensional feature fusion method in the identification of fracture-related infection

Fracture-related infection (FRI) is one of the most common and intractable complications in orthopedic trauma surgery. This complication can impose severe psychological burdens and socio-economic impacts on patients. Although the definition of FRI has been proposed recently by an expert group, the diagnostic criteria for FRI are not yet standardized. A total of 4761 FRI patients and 4761 fracture patients (Non-FRI) were included in the study. The feature set of patients included imaging characteristics, demographic information, clinical symptoms, microbiological findings, and serum inflammatory markers, which were reduced by the Principal Component Analysis. To optimize the Support Vector Machine (SVM) model, the Traction Switching Delay Particle Swarm Optimization (TSDPSO) algorithm, a recognition method was proposed. Moreover, five machine learning models, including TSDPSO-SVM, were employed to distinguish FRI from Non-FRI. The Area under the Curve of TSDPSO-SVM was 0.91, at least 5% higher than that of other models. Compared with the Random Forest, Backpropagation Neural Network (BP), SVM and eXtreme Gradient Boosting (XGBoost), TSDPSO-SVM demonstrated remarkable accuracy in the test set ([Formula: see text]). The recall of TSDPSO-SVM was 98.32%, indicating a significant improvement ([Formula: see text]). Compared with BP and SVM, TSDPSO-SVM exhibited significantly superior specificity, false positive rate and precision ([Formula: see text]. The five models yielded consistent results in the training and testing of FRI patients across different age groups. TSDPSO-SVM is validated to have the maximum overall prediction ability and can effectively distinguish between FRI and Non-FRI. For the early diagnosis of FRI, TSDPSO-SVM may provide a reference basis for clinicians, especially those with insufficient experience. These results also lay a foundation for the intelligent diagnosis of FRI. Furthermore, these findings exhibit the application potential of this model in the diagnosis and classification of other diseases.

Circumferential approach via dynamic position in OLIF combined with freehand screw pedicle fixation for lumbar tuberculosis requiring multilevel instrumentation: a 3-year retrospective study

PURPOSE

To advance a modified oblique lumbar interbody fusion (M-OLIF) achieving anterior debridement and posterior freehand instrumentation simultaneously in circumferential approach via dynamic position and compare with traditional combined anterior-posterior surgery (CAPS) in clinical and radiological evaluation.

PATIENTS AND METHODS

Innovative freehand instrumentation in floating position was described. Consecutive patients having undergone surgeries for lumbar tuberculosis from 2017 January to 2019 December had been retrospectively reviewed. Patients with follow-ups for at least 36 months were included and divided into M-OLIF or CAPS group according to surgical methods applied. Outcomes included operation time, estimated blood loss, complication profile for safety evaluation; Vascular Analogue Scale (VAS) and Oswestry Disability Index (ODI) for efficacy evaluation; C-reactive protein and Erythrocyte Sedimentation Rate for tuberculosis activity and recurrence evaluation; X-ray and CT scan for radiological evaluation.

RESULTS

Totally 56 patients had been enrolled in the study (26 for M-OLIF and 30 for CAPS). Compared with CAPS group, M-OLIF group illustrated significantly decreased estimated blood loss, operation time, hospital stay, and less postoperative morbidities. Meanwhile, M-OLIF group showed earlier improvement in VAS in 3 days and ODI in the first month postoperatively, without obvious discrepancy in further follow-ups. The overall screw accuracy in M-OLIF and CAPS group was 93.8% and 92.3% respectively, without significant difference in perforation distribution.

CONCLUSION

M-OLIF was efficient for lumbar tuberculosis requiring multilevel fixation, with reduced operation time and iatrogenic trauma, earlier clinical improvement compared with traditional combined surgery.

Efficacy of single-stage posterior surgery for HIV-positive patients with thoracolumbar tuberculosis

OBJECTIVE

We aimed to observe the clinical effect of single-stage posterior surgery on HIV-positive patients with thoracolumbar tuberculosis.

METHODS

From October 2015 to October 2019, 13 HIV-positive patients with thoracolumbar tuberculosis who underwent single-stage posterior surgery were retrospectively analyzed (observation group), and 13 HIV-negative patients with thoracolumbar tuberculosis who were matched with the gender, age, operative site, and surgical approach during the same period were selected as the control group. Postoperative complications, hemoglobin, albumin, CD4⁺T lymphocyte count, operative site, operative time, and blood loss were recorded between the two groups. The clinical efficacy was evaluated by the visual analog scale (VAS), American Spinal Injury Association (ASIA) scale, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), kyphotic angle, correction rate of kyphosis, angle loss, and bone graft fusion time.

RESULTS

In the observation group, 7 patients had postoperative complications, including 1 patient with cerebrospinal fluid leakage, 1 patient with nerve root irritation, 1 patient with an opportunistic infection, and 4 with delayed wound healing. In the control group, 2 patients developed postoperative complications, including 1 with nerve root irritation and 1 with delayed wound healing. There was no statistically significant difference in the incidence of postoperative complications between the two groups (P > 0.05). CD4⁺T lymphocyte count, hemoglobin, and albumin in HIV-positive patients with postoperative complications were statistically different from those without postoperative complications (P all < 0.05). No tuberculosis recurrence was found at the last follow-up, ESR and CRP returned to normal, and there were no statistically significant differences in bone graft fusion time, VAS score, ASIA scale, correction rate of kyphosis, and angle loss between two groups (P all > 0.05).

CONCLUSION

Single-stage posterior surgery for HIV-positive patients with thoracolumbar tuberculosis could achieve satisfactory clinical efficacy through comprehensive preoperative evaluation, standardized perioperative antiviral and anti-tuberculosis treatments, and prevention of postoperative complications.

Posterior transforaminal debridement and interbody fusion with instrumentation for multi-segment thoracic spinal tuberculosis: a midterm follow-up study

This retrospective study aimed to evaluate midterm outcomes of surgical management of multi-segment thoracic spinal tuberculosis by single-stage posterior transforaminal debridement and interbody fusion with instrumentation. From January 2007 to October 2015, 42 adult patients with thoracic spinal tuberculosis involving three or more levels underwent single-stage posterior transforaminal debridement, interbody fusion and instrumentation At a mean follow-up of 73.5 ± 9.6 months, all patients were eligible for final evaluation. All displayed improved biochemical markers and pain scores at 3 months and improved physiologic levels at the end of treatment. Visual analogue and 36-Item Short-Form Health Survey scores were significantly improved compared with preoperative values. All 30 patients with preoperative neurological deficits experienced neurologic improvement. Thoracic kyphosis angle decreased significantly from 34.4° ± 4.5° to 22.0° ± 2.6°. A mean kyphotic angle loss of 1.7° ± 1.1° was recorded at the final follow-up, and bone fusion was observed at a mean of 10.6 ± 2.1 months, with no instrumentation failures. One patient experienced delayed incisional healing and five patients suffered postoperative intercostal neuralgia that were cured by conservative treatment. There were no graft failures or implant breakages. This study showed the utility of a single-staged procedure combining posterior transforaminal debridement and interbody fusion with instrumentation, and demonstrated promising results.

One-Stage Posterior Vertebral Column Resection in the Treatment of Adolescent Thoracic and Lumbar Tuberculosis Complicated With Severe Kyphotic Deformity

BACKGROUND

Our study aims to investigate the clinical outcome of 1-stage posterior vertebral column resection (PVCR) for adolescent thoracic and lumbar tuberculosis with severe kyphotic deformity (Cobb angle≥60°).

METHODS

Between January 2008 and January 2016, we recorded 16 (9 male, 7 female) adolescent cases of thoracic and lumbar tuberculosis complicated with severe kyphotic deformity treated by 1-stage PVCR (average age: 15.38 ± 1.54 years; range: 13-18 years). The Cobb angle of kyphosis was 64.56° ± 3.41°. According to the American Spinal Injury Association (ASIA) classification, all patients were classified preoperatively. The lesions involved T4-T11 in 10 cases and T12-L2 in 6 cases.

RESULTS

The mean follow-up time was 19.06 ± 11.42 months (range: 12-48 months). Based on ASIA classification, postoperative grades were significantly increased compared with preoperative grades (P < 0.05), The mean Cobb angle was significantly corrected to 20.25° ± 13.83° at 1 week after surgery, when compared with preoperative Cobb angle (P < 0.05). There was no significant difference in Cobb angle between 1-week after operation and the last follow-up (20.69° ± 13.83°) (P > 0.05). All the patients achieved bony fusion at a mean time of 14 months (range: 10-20 months) postoperatively. No fixation loosening, displacement, or fracture was observed during follow-up.

CONCLUSIONS

One-stage PVCR is an effective surgical method for the treatment of adolescent thoracic and lumbar spinal tuberculosis with severe kyphotic deformity, which can completely remove the lesion, effectively correct the kyphosis deformity, and prevent related complications.

Comparison of anterior or posterior approach in surgical treatment of thoracic and lumbar tuberculosis: a retrospective case-control study

BACKGROUND

With the widespread use of the posterior surgery, more and more surgeons chose posterior surgery to treat thoracic and lumbar tuberculosis. But others still believed that the anterior surgery is more conducive to eradicating the lesions, and easier to place larger bone pieces for bone graft fusion. We compared the clinical and radiological outcomes of anterior and posterior surgical approaches and presented our views.

METHODS

This study included 52 thoracic and lumbar tuberculosis patients at Sun Yat-sen Memorial Hospital from January 2010 to June 2018. All cases underwent radical debridement, nerve decompression, intervertebral bone graft fusion and internal fixation. Cases were divided into anterior group (24 cases) and posterior group (28 cases). Statistical analysis was used to compare the clinical effectiveness, radiological outcomes, complications and other related information.

RESULTS

Patients in the anterior group and the posterior group were followed up for an average of 27.4 and 22.3 months, respectively. There were no statistically significant differences between groups in the preoperative, postoperative and last follow-up VAS score, ASIA grade and Cobb angle of local kyphosis. Moreover, there were no statistically significant differences in the improvement of neurological function, loss of kyphotic correction, total incidence of complications, operative time, intraoperative blood loss and hospital stay between the two groups (P > 0.05). But there was greater correction of kyphosis, earlier bone fusion, lower incidence of poor wound healing, less interference with the normal spine and less internal fixation consumables and medical cost in the anterior group (P < 0.05).

CONCLUSIONS

Both anterior and posterior approaches are feasible for thoracic and lumbar tuberculosis. While for thoracic and lumbar tuberculosis patients with a single lesion limited in the anterior and middle columns of the spine without severe kyphosis, the anterior approach surgery may have greater advantages in kyphosis correction, bone fusion, wound healing, protection of the normal spine, and medical consumables and cost.

Comparison of Clinical Data Between Patients With Complications and Without Complications After Spinal Tuberculosis Surgery: A Propensity Score Matching Analysis

Purpose

This study used a propensity score matching (PSM) analysis to explore the risk factors of post-operative complications and compared the differences in clinical data between them following spinal tuberculosis surgery.

Methods

The clinical data of patients with spinal tuberculosis were collected in our hospital from June 2012 to June 2021, including general information, laboratory results, surgical information, and hospitalization costs. The data were divided into two groups: complication and without complication groups. The baseline data of the two groups were obtained using the PSM analysis. Univariate and multivariate logistic analyses were used to analyze the differences between the two groups.

Results

A total of 292 patients were included in the PSM analysis: 146 patients with complications and 146 patients without complications. The operation time, incision length, hospital stay, and albumin quantity in the complications group were 162 ± 74.1, 11.2 ± 4.76, 14.7 ± 9.34, and 1.71 ± 2.82, respectively, and those in the without complication group were 138 ± 60.5, 10.2 ± 3.56, 11.7 ± 7.44, and 0.740 ± 2.44, respectively. The laboratory costs, examination costs, guardianship costs, oxygen costs, and total costs in the complications group were higher than those in the without complication group. A significant difference was observed in the albumin quantity by logistic regression analysis (P < 0.05).

Conclusion

Several costs in the complication group were higher than in the without complication group. The albumin quantity may be an independent factor to predict post-operative complications of spinal tuberculosis by logistic regression analysis.
