Comparison of clinical and radiological outcomes of local morselized bone grafts and structural iliac bone grafts in the treatment of lumbar tuberculosis with posterior-only surgery

BackgroundMany surgeons have reported results similar to those of anterior debridement and bone grafting in treating spinal tuberculosis in the lumbar region using only a posterior approach. However, there is still no consensus regarding bone graft methods. This study aims to compare the clinical and radiological outcomes of morselized versus structural iliac bone grafts in the treatment of lumbar tuberculosis via one-stage posterior surgery.MethodsA retrospective study was performed with 82 patients with lumbar tuberculosis who had undergone posterior-only debridement, bone grafting, and instrumentation between January 2014 and June 2018. Morselized bone grafts were used in 43 patients, whereas structural iliac bone grafts were used in 39 patients. The clinical data and imaging results of the patients were compared between the two groups to evaluate the clinical effects of the two types of grafts.ResultsThe operation time, blood loss and hospital stay values in the morselized bone group were significantly lower than those in the structural iliac bone group (p < 0.05). No significant differences were observed with respect to erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Cobb angle, or improvement of neurological function between the two groups. The VAS pain scores for low back and leg pain decreased significantly after the operation (p < 0.05). However, postoperatively, the VAS score was higher in the structural iliac bone group than in the morselized bone group, and there was no significant difference at the last follow-up between the two groups (p > 0.05). Bone fusion was achieved in 41 patients (95%) in the morselized bone group and 38 patients (97%) in the structural iliac bone group. There was no significant difference between the fusion rates of the two groups (p > 0.05).ConclusionThe two graft techniques achieved comparable clinical outcomes in lumbar spinal tuberculosis treatment. However, the morselized bone graft was more beneficial in terms of reducing surgical trauma and postoperative complications.

One-stage freehand minimally invasive pedicle screw fixation combined with mini-access surgery through OLIF approach for the treatment of lumbar tuberculosis

ObjectiveTo compare one-stage freehand minimally invasive pedicle screw fixation (freehand MIPS) combined with mini-access surgery through OLIF approach with posterior approach for treatment of lumbar tuberculosis (TB), and evaluate its feasibility, efficacy and safety in debridement, bone graft fusion and internal fixation.Methods48 patients with single segment lumbar TB from June 2014 to June 2017 were included. Among them, 22 patients underwent one-stage freehand MIPS combined with mini-access surgery through OLIF approach (group 1), 26 patients were treated with posterior open surgery (group 2). Duration of operation, blood loss, and stay time in hospital were compared. Pre- and postoperative visual analog scale (VAS) pain scores, Oswestry disability index (ODI), erythrocyte sedimentation rate, complications and images were also recorded.ResultsPatients in group 1 showed significantly less blood loss (165 ± 73 ml vs 873 ± 318 ml, P < 0.001), shorter stay time in hospital (6/4–8 days vs 12/8–15 days, P < 0.001), while longer duration of operation (185 ± 14 min vs 171 ± 12 min, P < 0.001) than group 2 did. VAS scores significantly decreased after surgery in both groups, however, VAS scores of group 1 were significantly lower than that of group 2 immediately after surgery and during follow-ups (P < 0.001). ODI of group 1 was also significantly lower than that of group 2 at 12-month after surgery (P < 0.001).ConclusionOne-stage freehand MIPS combined with mini-access surgery through OLIF approach is a feasible, efficient and safe method in treating single segment lumbar TB. It shows advantages of less surgical trauma and faster postoperative recovery.

Single-stage posterior resection of the transversal process combined with an intervertebral foraminal approach for debridement, interbody fusion, internal fixation for the treatment of lumbar tuberculosis and psoas major abscess.

To investigate the feasibility and clinical efficacy of the treatment for lumbar tuberculosis with psoas major abscess with single-stage posterior resection of the transversal process combined with an intervertebral foraminal approach for debridement, interbody fusion, internal fixation. Thisretrospectivestudy evaluated the clinical data of 24 patients (14 males and 10 females) with lumbar tuberculosis and psoas major abscess admitted to the Comprehensive Surgery from June 2016 to June 2019.All patients were treated with the single-stage posterior approach to remove the transverse process combined with the intervertebral foramina approach for debridement, interbody fusion, internal fixation. The quadruple anti-tuberculosis drug therapy was given both pre-operatively and post-operatively. Clinical symptoms and complications were investigated and recorded. The visual analogue scale (VAS), American Spinal Injury Association (ASIA), degree of lesion fusion C-reactive protein (CRP) levels, and erythrocyte sedimentation rate (ESR) were evaluated. The average follow-up period was 16. 5months (from 12 to 36months). The average VAS score at threemonths post-operation was significantly declined than the pre-operative VAS score [(2.17 ± 0.87) points vs (5.46 ± 1.22) points, t = - 11.534, P < 0.01)]. At the last follow-up, the neurological function of 20 patients recovered to grade E, whereas four patients were still in grade D. The ESR and CRP returned to normal levels in all patients. Bone fusion was achieved in nine cases at sixmonths, 11 cases at ninemonths, and four cases at 12months. The incisions of 23 patients had healed nicely without chronic sinus. Poor incision healing only happened in one case at the day 12 post-operation. The bone grafts among the lesions obtained bony fusion. Besides, there was no recurrence of tuberculosis, loosening or fracture of internal fixation during the follow-up. Single-stage posterior resection of the transversal process combined with an intervertebral foramina approach for debridement, interbody fusion, internal fixation is probably an effective and safe approach of the treatment for lumbar tuberculosis combined with psoas major abscess, producing few complications. This technique provides an alternative method for the surgical treatment of lumbar tuberculosis combined with psoas major abscess.

Minimally invasive direct lateral approach debridement, interbody bone grafting, and interbody fusion combined with posterior percutaneous pedicle screw fixation for lumbar spinal tuberculosis

To investigate the clinical efficacy and superiority of direct lateral interbody fusion combined with posterior percutaneous screw fixation in the treatment of lumbar tuberculosis. From June 2013 to August 2016, the clinical data of 83 patients with lumbar tuberculosis were retrospectively analyzed, including 55 males and 28 females, aged from 27 to 72 (49.5±13.5) years. These 83 patients were divided into two groups according to different operation methods, 35 cases in group A were treated with direct lateral interbody fusion combined with posterior percutaneous screw fixation;48 cases in group B were treated with anterior traditional extraperitoneal debridement combined with posterior internal fixation. After operation, regular quadruple antituberculosis drugs were continued for 18 months. The operation time, intraoperative blood loss, hospital stay, bone graft fusion time and complications were compared between the two groups. Visual analogue score (VAS) of lumbar pain, Oswestry Disability Index (ODI), sagittal Cobb angle, erythrocyte sedimentation rate (ESR) and C-reactive protein(CRP) values before and after operation were analyzed. The operation was successfully completed in both groups, and the operation mode was not changed during operation. The operation time, intraoperative blood loss and hospital stay were (149.4±13.3) min, (354.3±69.0) ml, (9.4±1.6) d in group A and(116.8±10.0) min, (721.9±172.3) ml, (11.8±1.7) d in group B, respectively, with significant difference between the two groups (P<0.05). The follow up time was (24.2±5.1) months in group A and (24.0±5.0) months in group B, there was no significant difference between two groups (P>0.05). At the follow-up of 4 months after operation, one patient in group A was found to have enlarged psoas major abscess on the contralateral side, and was cured after secondary operation. No sinus formation, cerebrospinal fluid leakage, internal fixation loosening, fracture or distal junction kyphosis were found during follow-up. The fusion time was (5.1±1.6) months in group A and (5.1± 1.7) months in group B, there was no significant difference between two groups (P>0.05). The VAS, ODI score, sagittal Cobb angle, ESR and CRP value of the lesion segment at the last follow-up of the two groups were significantly improved (P<0.05), but there was no significant difference between two groups (P>0.05). The two kinds of operation can obtain satisfactory clinical effect. Direct lateral interbody fusion combined with posterior percutaneous screw fixation can reduce intraoperative blood loss and hospital stay, which is conducive to early rehabilitation of patients.

Treatment of lumbar tuberculosis with percutaneous pedicle screw internal fixation and minimally invasive lateral small incisions lesion debridement and bone graft fusion via dilated channels

To explore the efficacy of percutaneous pedicle screw internal fixation and minimally invasive lateral small incisions lesion debridement and bone graft fusion via dilated channels in the treatment of lumbar tuberculosis. The clinical data of 22 cases of lumbar tuberculosis treated with percutaneous pedicle screw internal fixation combined with dilated channels with minimally invasive lateral small incision lesion debridement and bone graft fusion between January 2016 and June 2018 were retrospectively analyzed. There were 12 males and 10 females, with an average age of 47.5 years (range, 22-75 years). The affected segments were L 2, 3 in 5 cases, L 3, 4 in 8 cases, and L 4, 5 in 9 cases, with an average disease duration of 8.6 months (range, 4-14 months). Preoperative neurological function was classified according to the American Spinal Injury Association (ASIA), with 3 cases of grade C, 9 cases of grade D, and 10 cases of grade E. The operation time, intraoperative blood loss, and postoperative complications were recorded. At preoperation, 3 months after operation, and last follow-up, the C reactive protein (CRP) and erythrocyte sedimen- tation rate (ESR) were tested to evaluate tuberculosis control; the pain visual analogue scale (VAS) score was used to evaluate the recovery of pain, and the Oswestry disability index (ODI) was used to evaluate the function recovery of the patient's lower back; the kyphosis Cobb angle was measured, and the loss of Cobb angle (the difference between the Cobb angle at last follow-up and 3 months after operation) was calculated. At last follow-up, the ASIA classification was used to evaluate the recovery of neurological function, and the effectiveness was evaluated according to the modified MacNab standard. The operation time was 110-148 minutes (mean, 132.8 minutes) and the intraoperative blood loss was 70-110 mL (mean, 89.9 mL). Two patients experienced fat liquefaction of the incision and delayed healing; the incisions of the remaining patients healed by first intention. All patients were followed up 18-24 months, with an average of 21.3 months. All bone grafts achieved osseous fusion, the pedicle screws were fixed in reliable positions, without loosening, displacement, or broken rods. There was no recurrence of tuberculosis. The ESR, CRP, VAS scores, ODI scores, and kyphosis Cobb angle of the affected segment at 3 months after operation and last follow-up were significantly improved ( P<0.05); there were no significant differences between at last follow-up and 3 months after operation ( P>0.05), and the loss of Cobb angle was (0.6±0.5)°. The patient's neurological function recovered significantly. At last follow-up, the ASIA grades were classified into 1 case with grade C, 1 case with grade D, and 20 cases with grade E, which were significantly improved when compared with preoperative grading ( Z=-3.066, P=0.002). According to the modified MacNab standard, 16 cases were excellent, 3 cases were good, 2 cases were fair, and 1 case was poor. The excellent and good rate was 86.4%. Percutaneous pedicle screw internal fixation combined with dilated channels with minimally invasive lateral small incisions lesion debridement and bone graft fusion has the advantages of less bleeding, less trauma, and faster recovery, which is safe and effective in the treatment of lumbar tuberculosis.

The outcome of intervertebral surgery in the treatment of lumbar tuberculosis in children: A case series and long-term follow-up.

During the operation of treating lumbar tuberculosis in children, a long-segment or short-segment fixation, and fusion method were usually applied, which would adversely affect the function of normal motion unit. And so, we have been focusing on how we can shorten the range of fixation and fusion using intervertebral surgery. The objective of this retrospective study is to investigate the clinical outcome of intervertebral surgery, in the treatment of lumbar tuberculosis in children.From June 2003 to June 2013, 18 children with lumbar tuberculosis underwent intervertebral surgery, using a combined posterior and anterior approach, in our hospital. The surgical treatments included posterior pedicle screw fixation of affected vertebrae and posterolateral bone grafting, anterior debridement, compression, and strut bone grafting. Indicators such as preoperative and postoperative erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, neurological function, visual analog scale (VAS) score, kyphotic Cobb angle, complications, healing of lesions, bone graft healing, and recurrence were statistically analyzed.The mean follow-up time was 86.5 months (range, 62–120 months). Three months after the operation, all patients’ ESR and CRP levels decreased to normal, and both the American Spinal Injury Association neurological function scores and VAS scores improved. Successful bone graft healing was achieved, with lesions completely healed at 6 months after surgery, and no recurrence occurred. The preoperative kyphotic was 24.00° ± 13.15° (range −10°–39°), which decreased to −4.61° ± 7.31° (range −19°–10°) postoperative (Z = −4.34, P < .01); the mean deformity correction angle was 28.61° ± 8.43° (range 9°–43°). There was no significant difference between the kyphotic angle measured immediately after surgery at (−4.61° ± 7.31°) and the kyphotic angle measured at 5-year follow-up at (−3.11° ± 7.56°). The mean loss of correction was 1.50° ± 0.90°.Intervertebral surgery using a combined posterior and anterior approach is an effective and safe method for the treatment of lumbar tuberculosis in children. It can also preserve the function of normal motor segments to the maximum extent.

Treatment of Lumbar Tuberculosis by Mini-Open Anterior Approach Focal Cleaning Combined with Posterior Internal Fixation.

BackgroundThe aim of this study was to evaluate the efficiency and clinical outcomes of mini-open anterior approach focal cleaning combined with posterior internal fixation compared to conventional anterior extraperitoneal approach focal cleaning combined with posterior internal fixation in the treatment of lumbar tuberculosis (TB).Material/MethodsMedical records from 124 patients were collected from February 2010 to April 2015; patients were divided into two groups: group A (mini-open anterior approach focal cleaning combined with posterior internal fixation) and group B (conventional anterior extraperitoneal approach focal cleaning combined with posterior internal fixation in period I). The data on postoperative mechanical ventilation time, preoperative, postoperative, and last follow-up Cobb angle, visual analog scale (VAS), erythrocyte sedimentation rate (ESR), and Frankel classification were collected and analyzed. Operative complications, internal stability, and bone graft fusion were also observed.ResultsAll patients were followed-up for 12 to 36 months (average 22.5 months). Seven cases (five in group A and two in group B) had side psoas abscess and were cured after secondary drainage surgery. The rest of the cases were all cured after primary surgery, with no formation of sinus, incisional hernia, cerebrospinal fluid leakage, or recurrence of spinal TB, with no TB symptoms. Bone graft fusion ranged from 3 to 8 months (average 4.7 months). Compared to group B, group A, which had less time on postoperative mechanical ventilation, had a higher VAS score. Both groups had distinct improvements in Cobb angle, ESR, and Frankel classification after surgery.ConclusionsTreating lumbar TB by mini-open anterior approach focal cleaning combined with posterior internal fixation was safe and effective.

Objective To discuss the clinical efficacy of surgical treatment of pathologic vertebral surgery for thoracic and lumbar tuberculosis. Methods All of 322 cases of thoracic and lumbar spinal tuberculosis patients from December 2003 to June 2014 were retrospectively analyzed in our department. All patients were underwent debridement, fusion and nerve decompression surgery. According to different fixed methods, patients were divided into pathologic vertebral surgery group (fixation completed within lesions invaded motion unit) including 91 males and 100 females, with an average age of 41.53 years, and non-pathologic vertebral surgery group (long segments or short segment fixation) including 61 males and 70 females, with an average age of 42.72 years. We observed the tuberculosis cure rate, degrees of deformity, pain and neurological recovery, operative time, blood loss and complications by follow-up. Results The average follow-up time was 75.52 months in pathologic vertebral surgery group and 76.21 months in non-pathologic vertebral surgery group. The total number of pathologic vertebras in pathologic vertebral surgery group and non-pathologic vertebral surgery group were 277 and 218 respectively, and the average was 1.45 and 1.66. The total number of fixed segments was 277 in pathologic vertebral surgery group and 485 in non-pathologic vertebral surgery group, and the average fixed segments was 1.45 and 3.70. The cure rate was 85.86% in pathologic vertebral surgery group and 85.49% in non-pathologic vertebral surgery group at 6 months postoperatively, and 98.95% and 98.47% at the last follow-up time, with no significant difference between groups. Graft fusion rate was 89.00% in pathologic vertebral surgery group and 89.31% in non-pathologic vertebral surgery group 6 months postoperatively, 98.38% and 98.47% at the last follow-up time, without significant difference. In lumbar spine, the average correction of Cobb's angle was 12.4° in pathologic vertebral surgery group and 13.1° in non-pathologic vertebral surgery group, and the average angle loss was 1.3 and 1.4°, with no significant difference. In thoracolumbar, the average correction of Cobb's angle was 10.9°in pathologic vertebral surgery group and 11.1°in non-pathologic vertebral surgery group, and the average angle loss was 1.7°and 1.5° respectively, without significant difference. However, in thoracic, the average correction of Cobb's angle was 10.2° in pathologic vertebral surgery group and 12.7° in non-pathologic vertebral surgery group, and the average angle loss was 3.6° and 2.5°respectively, with significant difference. The mean operation time was 210.45 min in pathologic vertebral surgery group and 210.45 min in non-pathologic vertebral surgery group, with significant difference. The average blood loss was 726.12 ml in pathologic vertebral surgery group and 726.12 ml in non-pathologic vertebral surgery group, with significant difference. The complication rate was 11.51% in pathologic vertebral surgery group and 11.45% in non-pathologic vertebral surgery group, with no significant difference. Conclusion Pathologic vertebral surgery surgery is a safe, effective and feasible method of operation for treatment of thoracic and lumbar tuberculosis, which can effectively preserve adjacent normal vertebral motion unit features. The thoracic surgery was less satisfactory than the lumbar and thoracolumbar surgery. Key words: Thoracic vertebrae; Lumbar vertebrae; Tuberculosis, spinal; Bone transplantation; Treatment outcome
