[Clinical outcomes and bone resection analysis of unilateral double-channel endoscopic technique in treating lumbar disc herniation].

OBJECTIVE: To explore clinical outcomes and bone resection of interlaminar fenestration decompression and unilateral biportal endoscopic (UBE) technique in treating lumbar disc herniation(LDH). METHODS: A retrospective study was performed on 105 patients with single-level LDH treated from December 2019 to December 2021. Fifty-four patients in UBE group,including 32 males and 22 females,aged from 18 to 50 years old with an average of(38.7±9.3) years old,were treated with UBE,29 patients with L4,5 and 25 patients with L5S1. There were 51 patients in small fenestration group,including 27 males and 24 females,aged from 18 to 50 years old with an average of (39.9±10.0) years old,were treated with small fenestration,25 patients with L4,5 and 26 patients with L5S1. Perioperative indexes,such as operation time,postoperative time of getting out of bed and hospital stay were observed and compared between two groups. Visual analogue scale (VAS) and Oswestry disability index (ODI) were compared between two groups before operation and 1,3,6 and 12 months after operation,respectively;and modified MacNab evaluation criteria was used to evaluate clinical efficacy. Amount of bone resection and retention rate of inferior articular process laminoid complex were compared between two groups. RESULTS: All 105 patients were successfully completed operation. Both of two groups were followed up from 6 to 12 months with an average of (10.69±2.49) months. Operation time,postoperative time of getting out of bed and hospital stay were (58.20±5.54) min,(2.40±0.57) d and (3.80±0.61) d in UBE group,and (62.90±7.14) min,(4.40±0.64) d and (4.40±0.64) d in small fenestrum group,respectively;and had statistically difference between two groups(P<0.05). Postoperative VAS of low back and leg pain and ODI in both groups were significantly lower than those before surgery (P<0.05). VAS of lumbar pain in UBE group (1.37±0.49) score was lower than that of small fenestration group (2.45±0.64) score,and had statistically difference (t=9.745,P<0.05). Postoperative ODI in UBE group at 1 and 3 months were (28.54±3.31) % and (22.87±3.23) %,respectively,which were lower than those in small fenestra group (36.31±9.08) % and (29.90±8.36) %,and the difference was statistically significant (P<0.05). There were no significant difference in VAS and ODI between two groups at other time points (P>0.05). According to the modified MacNab evaluation criteria at the latest follow-up,49 patients got excellent result,3 good,and 2 fair in UBE group. In small fenestration group,35 patients got excellent,12 good,and 4 fair. In UBE group,amount of bone resection on L4,5 segment was (0.45±0.08) cm3 and (0.31±0.08) cm3 on the segment of L5S1. In small fenestration group,amount of bone resection on L4,5 segment was (0.57±0.07) cm3 and (0.49±0.04) cm3 on the segment of L5S1,and amount of bone resection of lower articular process laminar complex on the same segment in UBE group was less than that in small fenestration group (P<0.05). In UBE group,retention rate of laminoid complex on L4,5 segment was (0.73±0.04) and L5S1 segment was (0.83±0.03),while L4,5 segment was(0.68±0.06) and L5S1 segment was (0.74±0.04) in small fenestration group,the lower articular process laminar complex retention rate in UBE group was higher than that in small fenestration group(P<0.05). CONCLUSION: Both unilateral double-channel endoscopy and small fenestration of laminae could achieve good clinical results in treating LDH,but UBE has advantages of less trauma,higher efficiency,faster postoperative recovery and less damage to bone structure.

The safety and immunogenicity of a recombinant five-antigen Staphylococcus aureus vaccine among patients undergoing elective surgery for closed fractures: A randomized, double-blind, placebo-controlled, multicenter phase 2 clinical trial.

BACKGROUND: Vaccines are urgently required to control Staphylococcus aureus hospital and community infections and reduce the use of antibiotics. Here, we report the safety and immunogenicity of a recombinant five-antigen Staphylococcus aureus vaccine (rFSAV) in patients undergoing elective surgery for closed fractures. METHODS: A randomized, double-blind, placebo-controlled, multicenter phase 2 clinical trial was carried out in 10 clinical research centers in China. Patients undergoing elective surgery for closed fractures, aged 18-70 years, were randomly allocated at a ratio of 1:1 to receive the rFSAV or placebo at a regimen of two doses on day 0 and another dose on day 7. All participants and investigators remained blinded during the study period. The safety endpoint was the incidence of adverse events within 180 days. The immunogenicity endpoints included the level of specific antibodies to five antigens after vaccination, as well as opsonophagocytic antibodies. RESULTS: A total of 348 eligible participants were randomized to the rFSAV (n = 174) and placebo (n = 174) groups. No grade 3 local adverse events occurred. There was no significant difference in the incidence of overall systemic adverse events between the experimental (40.24 %) and control groups (33.72 %) within 180 days after the first immunization. The antigen-specific binding antibodies started to increase at days 7 and reached their peaks at 10-14 days after the first immunization. The rapid and potent opsonophagocytic antibodies were also substantially above the background levels. CONCLUSIONS: rFSAV is safe and well-tolerated in patients undergoing elective surgery for closed fractures. It elicited rapid and robust specific humoral immune responses using the perioperative immunization procedure. These results provide evidence for further clinical trials to confirm the vaccine efficacy.

Trends of epidemiological characteristics of traumatic spinal cord injury in China, 2009-2018.

OBJECTIVE: We focus on providing the first comprehensive national dataset on the incidence, injury aetiology and mortality of TSCI in China. METHODS: A multi-stage stratified cluster sampling method was used. We included TSCI cases from all hospitals in three regions, nine provinces and 27 cities in China via search of electronic medical records and retrospectively analysed the characteristics of TSCI in China from 2009 to 2018. We estimated the incidence of TSCI in the total population and subgroups. RESULTS: There were 5954 actual cases in 2009, corresponding to a total estimated TSCI incidence of 45.1 cases per million population (95% CI, 44.0-46.3). There were 10,074 actual cases in 2018, corresponding to a total estimated TSCI incidence of 66.5 cases per million population (95% CI, 65.2-67.8) (P < 0.001; annual average percentage change (AAPC), 4.4%). From 2009 to 2018, the incidence of almost all sex/age groups showed an increasing trend over time (P < 0.001; AAPC, 0.7-8.8%). The elderly population (aged 65-74) displayed the highest incidence of TSCI (with an average annual incidence of 127.1 cases per million [95% CI, 119.8-134.3]). CONCLUSIONS: The TSCI incidence increased significantly from 2009 to 2018. The incidence in the elderly populations was consistently high and continues to increase over time. The mortality of TSCI patients in hospitals is relatively low and continues to decrease each year, but elderly individuals remain at a high risk of hospital death.

Delayed neurological deficits caused by cement extravasation following vertebroplasty: a case report.

Delayed neurological deficits secondary to percutaneous vertebroplasty caused by cement leakage is a rare condition. Although cement extravasation during percutaneous vertebroplasty is not uncommon, most cases are clinically asymptomatic, and symptomatic cement extravasation that requires surgical excision is rarely reported. Herein, a case of L4 radiculopathy secondary to cement leakage is reported that involved the delayed onset of neurological symptoms. The patient was treated using a minimally invasive transforaminal endoscopic approach. The clinical and imaging findings and treatment methods are discussed.

Percutaneous transforaminal endoscopic discectomy versus microendoscopic discectomy for upper lumbar disc herniation: a retrospective comparative study.

BACKGROUND: The present study aimed to investigate the clinical outcomes of percutaneous transforaminal endoscopic discectomy (PTED) and microendoscopic discectomy (MED) in the treatment of upper lumbar disc herniation (ULDH). METHODS: A total of 62 ULDH patients treated with PTED or MED were enrolled in this study and were randomly divided into group A (PTED, n=31) and group B (MED, n=31). The characteristics, surgical duration, incision length, blood loss, volume of drainage, length of hospital stay, and the complications and recurrences of patients were recorded and compared between the two groups. The Japanese Orthopedic Association (JOA), Oswestry Disability Index (ODI), and visual analogue scale (VAS) scores were compared preoperatively, postoperatively, and at the final follow-up between group A and group B. The postoperatively clinical outcomes of patients were evaluated according to the modified MacNab criterion. RESULTS: The incision length, the duration of surgery, intraoperative blood loss, volume of drainage, and length of hospital stay in group A were less than those in group B (P<0.01). Compared with group B, the JOA scores of the patients in group A were significantly enhanced at 1 month (P<0.01), 3 months (P<0.01), and 6 months (P<0.01), the VAS scores were significantly improved at 1 month (P<0.01), 3 months (P<0.01), 6 months (P<0.05), and 12 months (P<0.05), and the ODI scores exhibited significant improvements at 1 month (P<0.01) and 3 months (P<0.05). CONCLUSION: PTED provides better results in the treatment of ULDH compared with MED. It is beneficial to improve the quality of life of patients and is worthy of promotion in clinical application.

The anterior versus posterior approach for the treatment of ossification of the posterior longitudinal ligament in the cervical spine: A systematic review and meta-analysis.

Study Design: Systematic review and meta-analysis.Objective: To compare the effectiveness and safety between anterior and posterior approach, and determine the best surgical methods for the treatment of ossification of the posterior longitudinal ligament (OPLL) in the cervical spine.Methods: We searched the Cochrane Library, PubMed, CNKI and Wanfang Med Data databases from January 2007 to March 2018. Japanese Orthopaedic Association (JOA) scores, cervical lordosis, functional recovery rates, excellent and good outcomes of the surgical approaches, and complication and reoperation rates were analyzed. RevMan 5.3 was utilized for data analysis.Results: Eleven studies were included in the meta-analysis. By comparing the anterior and posterior approaches for the treatment of OPLL in the cervical spine, statistically significant differences were found in the preoperative initial JOA, the postoperative final JOA scores, functional recovery rates, complication rates, excellent and good outcomes of the surgical approaches and reoperation rates. However, no statistically significant difference in the occurrence of the preoperative and postoperative cervical lordosis was noted.Conclusion: The anterior approach is superior to the posterior approach in terms of the postoperative final JOA score, functional recovery rate, and clinical outcomes. Although the complication and reoperation rates of the anterior approach are higher than those of the posterior approach. We recommend the anterior approach for the treatment of OPLL when patients with occupying ratio ≥ 60%. In addition, high-quality studies with long-term follow-up and large sample size are also needed.

Combined anterior and posterior ankle impingement syndrome with nonunion of Cedell fracture in a 58-year-old female: a case report.

BACKGROUND: Combined anterior and posterior ankle impingement has seldom been reported. Cedell fracture, fracture of posteromedial tubercle of talus, is an uncommon and easily missed injury which may elicit posteromedial ankle impingement. The injury mechanisms and management strategies of these two lesions have been reported individually. But the concurrent lesion of both of them has not been reported. CASE PRESENTATION: We reported a 58-year-old female with combined anterior and posterior ankle impingement syndrome with nonunion of Cedell fracture in whom open osteophytes debridement, fracture internal fixation and posterior talotibial ligament reconstruction were performed. The AOFAS hindfoot score was 90 at 1 year follow-up. To our knowledge, this was the first reported case with anterior, posterior and posteromedial impingement which was treated operatively with an excellent short-term outcome. CONCLUSIONS: To fully recognize this occult lesion and avoid missing is imperative for reducing the morbidities. We suggest CT and MRI as excellent imaging modalities that can help the timely diagnosis and appropriate treatment for this combined impingement with circumferential lesions.

[A retrospective study on risk factors associated with postoperative delirium in elderly patients with spinal operation].

OBJECTIVE: To investigate the incidence and risk factors of delirium after spinal surgery in elderly patients. METHODS: A retrospective analysis was performed on 436 patients with spinal surgery from January 2016 to November 2018. According to delirium occurrancy after the operation, 436 cases were divided into two groups:delirium group and non-delirium group. Body mass index(BMI), history of diabetes, history of coronary heart disease, history of chronic obstructive pulmonary disease (COPD), preoperative white blood cell count, preoperative erythrocyte volume, preoperative hemoglobin level, operation mode, operation time, anesthesia time, American Association of Anesthesiologists(ANA)(ASA) score, cardiac function grading(NYHA), intraoperative blood loss, intraoperative blood transfusion, intraoperative fentanyl, propofol and Dizocine dosage, postoperative white blood cell count, postoperative erythrocyte volume, postoperative hemoglobin level, postoperative electrolytes (sodium, potassium) and univariate logistic regression analysis were used to analyze the risk factors. The independent risk factors were further investigated by multivariate Logistic regression analysis. RESULTS: Among 436 cases, 112 elderly patients had postoperative delirium, the incidence of delirium was about 25.68%. The age, preoperative leukocyte count, erythrocyte specific volume, postoperative hemoglobin level in delirium group and non-delirium group were measured. There were significant differences in the postoperative sodium concentration, anesthesia time, ASA score, cardiac function grading, blood loss during operation, postoperative use of Dizocine, history of diabetes, history of coronary heart disease and history of COPD (P<0.05). Multivariate logistic regression analysis showed that the age, ASA score, postoperative Dizocine volume, and COPD history were independent risk factors for the occurrence of delirium after spinal surgery in elderly patients. CONCLUSIONS: The elderly patients over 72 years old, the ASA score>2, the use of Dizocine analgesic and the patients with COPD are the independent risk factors of postoperative delirium.

Integrated approach to pain management for a patient with multiple bone metastases of uterine cervical cancer.

Background Pain management for multiple bone metastases is complex and often requires multidisciplinary treatment. We herein describe patient-centered multidisciplinary pain management for metastatic cancer. CASE PRESENTATION: A 61-year-old woman with multiple bone metastases of uterine cervical cancer developed intractable low back pain. After external beam radiotherapy failed, we performed lumbar spinal intralesional curettage, pedicle screw fixation, and nerve decompression. However, the neuralgia persisted. We then percutaneously injected epirubicin into the intervertebral foramina under computed tomography guidance for L5 dorsal root ganglion destruction. Osteoplasty was performed under C-arm X-ray guidance; however, the sacrum was mistaken for the ilium, and treatment was ineffective. We administered zoledronic acid and strontium-89. The last resort was outpatient implantation of an epidural bupivacaine-morphine infusion system. A visual analog scale (VAS) was used for pain evaluation. Lumbar spinal intralesional curettage and fixation, epirubicin-induced ganglion destruction, and administration of zoledronic acid and strontium-89 decreased her VAS pain score from 7-8 to 3-4. Radiotherapy and nerve decompression and release were ineffective, as was osteoplasty because of the location error. The epidural infusion system decreased the VAS score from 7-8 to 2-3 and was highly efficient. Conclusions Multidisciplinary integrated treatment for metastatic cancer can be effective.

α-Linolenic Acid Inhibits Receptor Activator of NF-κB Ligand Induced (RANKL-Induced) Osteoclastogenesis and Prevents Inflammatory Bone Loss via Downregulation of Nuclear Factor-KappaB-Inducible Nitric Oxide Synthases (NF-κB-iNOS) Signaling Pathways.

BACKGROUND Inflammation is a major cellular strain causing increased risk of osteo-degenerative diseases. Omega-3 fatty acids have been great source in suppressing inflammation. We investigated the effect of α-linolenic acid (ALA) on RANKL-stimulated osteoclast differentiation, LPS-induced and ovariectomized bone loss in mice models. MATERIAL AND METHODS The bone marrow macrophages (BMMs) were isolated from femurs of ICR mice, stimulated with RANKL, and treated with ALA (100, 200, 300 µM). Major analytical methods include histological analysis, osteoclasts viability assay, serum cytokines and chemokines ELISA, and gene expression by qPCR. RESULTS ALA intervention inhibited RANKL-induced osteoclasts proliferation and differentiation. ALA inhibited bone resorption activity as measured by materialization of F-actin ring structures as well. ALA suppressed the RANKL-induced osteoclast markers c-Fos, c-Jun and NFATc1 together with transcription factor proteins TRAP, OSCAR, cathepsin K and ß3-integrin. ALA also suppressed the RANKL-stimulated phosphorylation of JNK, ERK, and AKT as well as NF-κB and BCL-2 proteins. ALA intervention (100 and 300 mg/kg) to LPS-challenged mice showed annulled morphometric changes induced by LPS by suppressing the levels of proinflammatory cytokines and chemokines. ALA (100 and 300 mg/kg) intervention to estrogen-deficiency induced bone loss mice (ovariectomized) showed reductions in TRAP+ osteoclasts count, CTX-I expression, levels of IL-1ß, IL-2, IL-6, IL10, TNF-α and MCP-1 and iNOS and COX-2. CONCLUSIONS ALA suppresses RANKL-induced osteoclast differentiation and prevents inflammatory bone loss via downregulation of NF-κB-iNOS-COX-2 signaling. ALA is suggested to be a preventive herbal medicine against inflammatory bone disorders.

Ilizarov technique and limited surgical methods for correction of post-traumatic talipes equinovarus in children.

BACKGROUND: The objective of this study was to evaluate the efficacy and safety of using Ilizarov invasive distraction technique combined with limited surgical operations in the treatment of post-traumatic talipes equinovarus in children. METHODS: Eighteen cases of post-traumatic deformed feet in 15 patients who received the treatment of Ilizarov frame application, limited soft-tissue release or osteotomy were selected in this study. After removal of the frame, an ankle-foot orthosis was used continuously for another 6-12 months. Pre- and post-operatively, the International Clubfoot Study Group (ICFSG) score was employed to evaluate the gait and range of motion of the ankle joint. Radiographical assessment was also conducted. RESULTS: Patients were followed up for 22 (17-32) months. Ilizarov frame was applied for a mean duration of 5.5 (4-9) months. When it was removed, the gait was improved significantly in all the patients. The correction time was 6-8 weeks for patients who underwent soft-tissue release and 8-12 weeks for those with bone osteotomy. At the last follow-up assessment, the differences between pre- and post-operative plantar-flexion angle, dorsiflexion, motion of ankle joint and talocalcaneal angle were significant (all P < 0.05). The observed complications included wire-hole infection in one foot, toe contracture in one, residual deformity in three, recurrence of deformity in two and spastic ischaemia in one foot. CONCLUSION: Our findings suggest that Ilizarov technique combined with limited surgical operation can be considered as an efficient and successful method for correction of post-traumatic talipes equinovarus in children.

[Total hip arthroplasty for post-traumatic arthritis after internal fixation of acetabular fracture].

OBJECTIVE: To study the clinical outcome of total hip arthroplasty(THA) for traumatic arthritis after acetabular fracture. METHODS: From June 2010 to June 2014, 33 hips in 33 patients with traumatic arthritis after acetabular fracture were retrospective analyzed including 21 males and 12 females with a mean age of 44.6 years old. All the patients received THA with bio-prostheses. Harris score was used to evaluate the hip function of patients before and after operation, the X-ray was adopted for radiographic evaluation of the hip prosthesis. RESULTS: All patients were followed up for 7 to 38 months with an average of 21.6 months. The Harris score increased from preoperative 53.6±2.4 to 94.0±3.0 at the final follow-up, the difference was statistically significant(t=55.37, P<0.05). The X-ray evaluation showed the prosthesis was in good position, no loosening of the prosthesis, dislocation and periprosthetic osteolysis. CONCLUSIONS: THA is an effective treatment for the traumatic arthritis after acetabular fracture;internal fixation of acetabular fractures could not be removed if it shows difficult but does not affect the prosthesis placement.

Bacterial Infection in Deep Paraspinal Muscles in a Parturient Following Epidural Analgesia: A Case Report and Literature Review: A CARE-Compliant Article.

Bacterial infection related to epidural catheterizations could occur. In general, the incidence of postoperative infection at the insertion site is very low. Paucity literatures are reported for paraspinal muscle infection after epidural analgesia in parturient. We report a case of paraspinal muscle infection shortly after epidural analgesia in a parturient, who was subjected to because of threatened preterm labor. Epidural morphine was administered for 2 days for childbirth pain control. She began to have constant low-back pain and fever on postpartum Day 2. Magnetic resonance image revealed a broad area of subcutaneous edema with a continuum along the catheter trajectory deep to the paraspinal muscles. A catheter-related bacterial infection was suspected. The surgical debridement and drainage was required combined with intravenous antibiotics on postpartum Day 3. She was soon cured uncomplicatedly. Epidural analgesia is effective to control labor pain and, in general, it is safe. However, the sequelae of complicated infection may be underestimated. A literature search yielded 7 other cases of catheter-related epidural abscess or soft tissue infection. Vigilance for these infections, especially in postpartum patients with backache, is needed. Moreover, early detection and proper treatment of infectious signs at postanesthetic visit are very important.

Single and combined use of human parathyroid hormone (PTH) (1-34) on areal bone mineral density (aBMD) in postmenopausal women with osteoporosis: evidence based on 9 RCTs.

BACKGROUND: Human parathyroid hormone (PTH) (1-34) or teriparatide (TPTD) is an anabolic agent for osteoporosis. This recombinant protein stimulates positive bone formation balance and bone remodeling. However, when concomitantly used with antiresorptive (AR) agents, previous studies reported conflicting results in their potential additive and synergistic effects on bone metabolism and bone mineral density (BMD). This study aimed to integrate previous evidence to assess the effect of TPTD monotherapy and the additive effect of TPTD on AR agents in postmenopausal women with osteoporosis. MATERIAL AND METHODS: This meta-analysis identified 9 RCTs from databases. To assess the therapeutic effect on osteoporosis, the weighted mean differences (WMDs) were used to pool the percentage change of BMD along with the 95% confidence intervals (CIs). BMD of 3 skeletal sites, including lumbar spine, total hip, and femoral neck were assessed. RESULTS: TPTD alone could significantly improve BMD of all 3 skeletal sites compared with placebo, although the effect on the femoral neck was less conclusive. The additive effect of TPTD over hormone replacement therapy (HRT) and denosumab (DEN) agents is evident in all 3 skeletal sites. But TPTD plus Alendronate (ALN) did not demonstrate additive effect in total hip and femoral neck. CONCLUSIONS: TPTD alone could significantly improve BMD of lumbar spine, total hip, and femoral neck. BMD outcomes of concomitant use of TPTD and AR agents are site-dependent and vary depending on the specific AR agent used and the timing of AR therapy initiation.

[Analysis of the reason of secondary fracture after percutaneous vertebroplasty for osteoporotic vertebral compression fractures].

OBJECTIVE: To explore the reasons of secondary fracture after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCFs) and discuss the measure of prevention and cure. METHODS: From January 2011 to January 2013, the clinical data of 180 patients with primary OVCFs treated by PVP were retrospectively analyzed. There were 75 males and 105 females, aged from 68 to 95 years old with an average of (79.50 ± 5.45) years. The involved vertebrae were identified according to the clinical symptoms and imaging data. PVP were performed in 362 vertebrae and the patients were followed up with an average of 12 months. Subsequent vertebral fractures were found through the pain's reappearance and MRI or bone scan. The patients were divided into secondary fracture group and no-secondary fracture group according to the subsequent fractures or no. Secondary fracture group was divided into two groups according to gender, and the patients with secondary fracture were also categorized into the original surgical vertebral fractures, adjacent vertebral fracture and remote vertebral fractures. The age, gender, the cement volume, the cement leakage, secondary fracture site, the incidence and type of secondary fracture were observed and compared among different groups. RESULTS: Among the 362 vertebrae of PVP, there were 109 vertebrae in male and 253 vertebrae in female. And 27 vertebrae (10 in male and 17 in female) of 22 cases (9 males and 13 females) occurred secondary fracture. The second PVP were performed in 13 cases (16 vertebrae) and the third PVP in 2 cases (4 vertebrae); 7 cases (7 vertebrae) were treated with conservative therapy. There was no statistically significant difference on age, gender, cement volume and leakage between secondary fracture group and no-secondary fracture group (P > 0.05). There was no statistically significant difference on the incidence and type of secondary fracture between male and female (P > 0.05). No significant difference was found on the adjacent and remote vertebral fractures (P > 0.05). Most of secondary fracture occurred in 6 months, and whether the single and double side injection, cement leakage had no obvious relation. CONCLUSION: There is no significant difference in the subsequent fracture after PVP for the OVCFs different gender and fractured site, and also no significant difference in the adjacent and remote vertebral fractures. The report didn't support the biomechanical viewpoint that vertebral body stiffness increasing after PVP would lead to adjacent vertebral stress increasing and result easily in adjacent vertebral fracture. Secondary fracture occurs always in 6 months after operation, which is the natural course of osteoporosis.

One-stage anterolateral surgical treatment for lumbosacral segment tuberculosis.

PURPOSE: The purpose of this study was to evaluate clinical outcomes following one-stage anterior radical debridement, interbody fusion, and sacral rod fixation for the treatment of lumbosacral segment tuberculosis. METHODS: From March 2004 to November 2008, 11 patients diagnosed with spinal tuberculosis received antituberculosis medications for two to three weeks before anterior radical debridement, autologous iliac bone grafting, and internal sacral rod fixation. Surgery was performed when the toxic symptoms of tuberculosis were controlled and erythrocyte sedimentation rates (ESR) decreased to 37.2 ± 9.6 mm/h (25-54 mm/h). Lumbosacral angle, visual analogue scale (VAS) pain, ESR, and neurological performance were assessed before and after surgery. RESULTS: All surgical procedures were performed successfully without intra or postoperative complication. There were no instances of spinal tuberculosis recurrence. Patients were followed-up for a mean of 19.6 months. The mean lumbosacral angle was significantly increased from the mean preoperative angle (12.9 ± 5.0°) both postoperatively (21.5 ± 6.1°) and at final follow-up (20.1 ± 5.2°) (both P <0.001). The mean VAS scores and ESR were significantly decreased from preoperative levels (7.3 ± 1.2 and 37.2 ± 9.6 mm/h, respectively) both postoperatively (1.5 ± 0.5 at month six and 10.4 ± 4.5 mm/h at month three, respectively) and at final follow-up (0.6 ± 0.5 and 10.5 ± 2.3 mm/h, respectively) (all P <0.001). Bone fusion occurred in all patients at a mean of nine months (range six to 12 months) after surgery. Three patients who had impaired neurological performance before surgery had normal neurological performance after surgery. CONCLUSION: Our findings suggest that anterior radical debridement, interbody fusion, and sacral rod fixation can be an effective treatment option for lumbosacral segment tuberculosis.
