RESUMO

AIMS: It is uncertain whether instrumented spinal fixation in nonambulatory children with neuromuscular scoliosis should finish at L5 or be extended to the pelvis. Pelvic fixation has been shown to be associated with up to 30% complication rates, but is regarded by some as the standard for correction of deformity in these conditions. The incidence of failure when comparing the most caudal level of instrumentation, either L5 or the pelvis, using all-pedicle screw instrumentation has not previously been reported. In this retrospective study, we compared nonambulatory patients undergoing surgery at two centres: one that routinely instrumented to L5 and the other to the pelvis. METHODS: In all, 91 nonambulatory patients with neuromuscular scoliosis were included. All underwent surgery using bilateral, segmental, pedicle screw instrumentation. A total of 40 patients underwent fusion to L5 and 51 had their fixation extended to the pelvis. The two groups were assessed for differences in terms of clinical and radiological findings, as well as complications. RESULTS: The main curve (MC) was a mean of 90° (40° to 141°) preoperatively and 46° (15° to 82°) at two-year follow-up in the L5 group, and 82° (33° to 116°) and 19° (1° to 60°) in the pelvic group (p < 0.001 at follow-up). Correction of MC and pelvic obliquity (POB) were statistically greater in the pelvic group (p < 0.001). There was no statistically significant difference in the operating time, blood loss, or complications. Loss of MC correction (> 10°) was more common in patients fixated to the pelvis (23% vs 3%; p = 0.032), while loss of pelvic obliquity correction was more frequent in the L5 group (25% vs 0%; p = 0.007). Risk factors for loss of correction (either POB or MC) included preoperative coronal imbalance (> 50 mm, odds ratio (OR) 11.5, 95%confidence interval (CI) 2.0 to 65; p = 0.006) and postoperative sagittal imbalance (> 25 mm, OR 11.0, 95% CI1.9 to 65; p = 0.008). CONCLUSION: We found that patients undergoing pelvic fixation had a greater correction of MC and POB. The rate of complications was not different. Preoperative coronal and postoperative sagittal imbalance were associated with increased risks of loss of correction, regardless of extent of fixation. Therefore, we recommend pelvic fixation in all nonambulatory children with neuromuscular scoliosis where coronal or sagittal imbalance are present preoperatively.

RESUMO

BACKGROUND: Lumbar spinal stenosis (LSS) is a common and frequently-occurring disease in the elderly. Percutaneous endoscopic decompression (PED) has become the first choice for the treatment of LSS because of its small wound, mild pain and rapid recovery. The surgical approaches are mainly divided into percutaneous interlaminar approach and transforaminal approach. However, these two surgical approaches have their own advantages, disadvantages and indications. Hence, the present study aims to synthesize the available direct and indirect evidence of transforaminal approach and interlaminar approach to prove their respective advantages and disadvantages. METHODS: The following databases will be searched: Cochrane Library, PubMed, Web of Science, Embase, CNKI, Wanfang data, and China Biomedical Literature Database (CBM). The search dates will be set from the inception to November 2019. Two researchers independently screened the literature, extracted the data and assessed the risk of bias in the included studies. The efficacy outcomes including: Back and Leg Visual Analog Scale (VAS) score, the MacNab criteria, the Oswestry Disability Index (ODI) and Japanese Orthopedic Association (JOA) score. The safety outcomes including: incidence of complications (dura tear, incomplete decompression, reoperation, etc.). The meta-analysis will be conducted using Stata 12.0 software. Grading of Recommendations Assessment, Development and Evaluation (GRADE) will be used to assess evidence quality. RESULTS: The results of this meta-analysis will be published in a peer-reviewed journal. CONCLUSION: The meta-analysis will provide a comprehensive summary of the evidence for 2 approaches to PED in patients with LSS. PROTOCOL REGISTRATION NUMBER: CRD42019128080.

RESUMO

Proximal junctional failure (PJF) is the greatest challenge after posterior lumbar interbody fusion (PLIF). The aim of this study was to evaluate the effectiveness of percutaneous cement injection (PCI) for PJF after PLIF patients requiring surgical revision.In this retrospective clinical study, we reviewed 7 patients requiring surgical revision for PJF after PLIF with 18 months follow-up. They received PCI at the collapsed vertebral body and supra-adjacent vertebra, with or without intervertebral disc intervention. The outcome measures were radiographic findings and revision surgery. Two different radiographic parameters (wedging rate (%) of the fractured vertebral body and local kyphosis angle) were used, and were performed before and immediately after PCI, and 18 month after the PCI.In our study, we showed that 5 of 7 patients who experienced PJF after PLIF did not receive any revision surgery after PCI. Immediately after cement injection, the anterior wedging rate (%) and the local kyphosis angle were significantly improved (P = .018, P = .028). The anterior wedging rates (%) and local kyphosis angle, at pre-PCI, immediate after PCI, and at final follow-up, were not significantly different between the non-revision surgery and revision surgery groups.Five of 7 patients who experienced PJF after PLIF did not receive revision surgery after PCI. Considering that general anesthesia and open surgery are high-risk procedures for geriatric patients, our results suggest that non-surgical PCI could be a viable alternative treatment option for PJF.SMC2017-01-011-001.

RESUMO

INTRODUCTION: Direct repair of the pars defect in lumbar spondylolysis is an effective surgical procedure, but it is technically challenging. We assessed the feasibility of a new robotic system for intralaminar screw fixation of spondylolysis. PATIENT CONCERNS: A 26-year-old man complained about frequent low back pain after failed conservative treatments. DIAGNOSIS: The lumbar computed tomography images demonstrated the presence of bilateral spondylolysis at the L5 level, with no spondylolisthesis. INTERVENTIONS: We performed one surgery of direct intralaminar screw fixation under the guidance of the TiRobot system. The trajectory of the screw was planned based on intraoperative 3-dimensional radiographic images. Then, the robotic arm spontaneously moved to guide the guide wires and screw insertion. OUTCOMES: Bilateral L5 intralaminar screws were safely and accurately placed. No intraoperative complications occurred. Postoperative computed tomography showed good radiological results, without cortical perforation. CONCLUSION: We report the first case of robot-assisted direct intralaminar screw fixation for spondylolysis using the TiRobot system. Robotic guidance for direct repair of spondylolysis could be feasible.

RESUMO

We report a rare case of bony diastematomyelia associated with intraspinal teratoma. The patient was surgically treated with bony diastematomyelia and intradural teratoma resection, followed by lumbar duroplasty, and posterior fusion from L2-L4 in order to maintain the spinal stability of the approached segments. Despite the risks, it was necessary to perform early surgical treatment because of rapid neurologic deterioration. The patient had a good postoperative outcome.

RESUMO

OBJECTIVE: This study aims to report the clinical outcome of stand-alone lateral lumbar interbody fusion (LLIF) on recurrent disk herniation and to compare the outcome of stand-alone LLIF to that of conventional transforaminal lumbar interbody fusion (TLIF). METHODS: A retrospective study of 47 patients with recurrent disk herniation was included from January 2008 to October 2016. The inclusion criteria were 1) with recurrent disk herniation that needs revision surgery, 2) with only 1 previous percutaneous endoscopic lumbar diskectomy surgery, 3) underwent 1-level stand-alone LLIF or 1-level TLIF surgery, and 4) with follow-up more than 1 year. Patients were asked to complete the following questionnaires for outcome evaluation: visual analog scales (VAS) for both low back pain and leg pain, the Oswestry Disability Index (ODI), and the 12-item Short-Form Health Survey. RESULTS: Eighteen patients underwent stand-alone LLIF, and 29 patients underwent TLIF surgery. Radiographic analysis revealed a similar baseline and postoperative lumbar lordosis in both the LLIF and TLIF groups. Two weeks after surgery, the ODI and VAS scores showed a significant decrease in both groups. The TLIF group showed significantly larger postoperative VAS back pain after surgery (P = 0.03). For both VAS leg pain and ODI score during follow-up, no significance difference was found between the LLIF and TLIF groups. CONCLUSIONS: Stand-alone LLIF is a safe and effective approach with low morbidity and acceptable complication rates for patients with recurrent disk herniation after a previous percutaneous endoscopic lumbar diskectomy surgery. Compared with the TLIF procedure, LLIF could achieve a similar improvement of patient-reported outcome with a better VAS back pain score.

RESUMO

OBJECTIVE: This study aimed to present a new endoscopic technique for osteoid osteoma (OO) of the lumbar spine and sacrum and to evaluate its safety and effectiveness. METHODS: Eleven consecutive patients with spinal OO underwent percutaneous endoscopic excision and ablation (PEEA) between March 2014 and May 2018. A cannula 0.7 cm in diameter was used for the procedure. According to the size of the nidus, whole-piece removal and piecemeal intralesional resection were used. Afterward, ablation was performed using an endoscopic radiofrequency electrode in the residual osteoma cavities. Clinical outcomes were assessed by Visual Analog Scale (VAS) scores. The efficacy of this technique was assessed using relevant clinical data and postoperative radiographs. RESULTS: The niduses of the 11 patients were all located in the posterior element of the lumbar spine and sacrum (10 in the lumbar spine and 1 in the sacrum). The preoperative VAS score was 7.18 (range, 6-9), the score on postoperative day 1 was 1 (range, 0-2), and the last follow-up VAS score was 0.27 (range, 0-1). All patients were discharged within 24 hours after surgery. The mean follow-up period was 21.8 months (range, 12-36 months). No serious complications were observed during the follow-up period. CONCLUSIONS: PEEA is a safe and effective technique for OO in the lumbar spine and sacrum in which the nidus is located in the posterior element. However, it has a steep learning curve. Further research with a larger and more comprehensive sample population is warranted.

RESUMO

BACKGROUND: Epidermoid cysts (ECs) account for 0.5% to 1% of all spinal tumors. They can be congenital or acquired. Acquired spinal ECs are extremely rare and are mostly caused by trauma, or secondary to iatrogenic procedure such as lumbar punctures or surgery for spina bifida. As far as we know, this is the first report of a spinal EC complicating surgery for a lumbar disc herniation. CASE DESCRIPTION: A 69-year-old woman, with a history of L3-L4 lumbar disc herniation surgery 30 years earlier, presented because of low back pain, weakness of her lower limbs, and bladder dysfunction evolving for 2 years. Magnetic resonance imaging identified an intradural cystic lesion extending from the medullary cone to the L4 level, evoking an EC. The diagnosis was confirmed peroperatively. Neurologic motor signs improved postoperatively but not the sphincter disorders. CONCLUSIONS: Despite the extreme rarity of this event, we should be aware of the potential de novo development of epidermoid tumors in patients who undergo surgery for lumbar disc herniation. Concerns must be given to persistent low back pain and delayed neurologic symptoms in these patients.

RESUMO

OBJECTIVE: We compared the safety and effectiveness of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) to open TLIF (O-TLIF) for lumbar degenerative disease. METHODS: We systematically searched Medline, Embase, and the Cochrane Central Register of Controlled Trials for randomized trials of MI-TLIF versus O-TLIF. The perioperative outcomes included the procedure time, fluoroscopy time, blood loss, complications, and hospital stay. The midterm outcomes included pseudarthrosis, the Oswestry Disability Index, and pain severity-all reported at 1-year minimum follow-up. RESULTS: A total of 7 randomized trials including 496 patients (246 MI-TLIF; 250 O-TLIF) were included in our review. No statistically significant group differences in procedure time (mean difference [MD], -4 minutes; P = 0.70) were found. However, the fluoroscopy time was significantly longer with MI-TLIF (MD, 48 seconds; P < 0.001). MI-TLIF resulted in less perioperative blood loss (MD, -200 mL; P < 0.001) and shorter hospitalization (MD, -2.2 days; P < 0.001) compared with O-TLIF. The risk of perioperative complications was comparable between the 2 groups (risk ratio, 1.03; P = 0.94). No group differences were found in the incidence of pseudarthrosis at the 1-year minimum follow-up (risk ratio, 0.84; P = 0.67). Pain severity at midterm follow-up was comparable between the 2 groups (MD, -1; P = 0.59), and the ODI was slightly lower in the MI-TLIF group (MD, -3; P = 0.01). CONCLUSION: Relative to O-TLIF, MI-TLIF was associated with less blood loss, a shorter hospital stay, and slightly less disability, at the expense of longer fluoroscopy times.

RESUMO

OBJECTIVE: To elucidate the correlation between changes in spinal/pelvic sagittal parameters and clinical treatment outcomes after oblique lumbar interbody fusion (OLIF). METHODS: Eighty-two patients with lumbar degenerative disease (LDD) treated by OLIF were retrospectively analyzed. The visual analog scale (VAS) score and Oswestry Disability Index (ODI) score were compared before and after surgery. Disk height (DH) and various spinal/pelvic sagittal parameters, including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), and sagittal vertical axis (SVA), were measured preoperatively and at the last postoperative follow-up. The correlation between the changes in sagittal parameters before and after surgery and the clinical treatment outcomes were observed. RESULTS: ODI score, VAS score, and DH were significantly better at the last follow-up compared with before surgery. The change in PI was not statistically significant before and after surgery. PT significantly decreased and SS and LL significantly increased after surgery. Significant linear relationships were found for several independent variables (difference in DH before and after surgery, postoperative LL, difference in LL before and after surgery, PI-LL match status, and SVA status) and the dependent variable ODI. The difference in DH before and after surgery showed the strongest correlation. The percentages of PI-LL match were 37% before surgery and 66% after surgery. The percentage of the normal SVA was 9% before surgery and 62% after surgery. CONCLUSIONS: OLIF for treatment of LDD had significant clinical outcomes, effectively restored the spinal/pelvic sagittal balance, and helped to improve the patients' clinical conditions.

RESUMO

BACKGROUND: Spinopelvic sagittal parameters have a significant influence on adjacent segment degeneration (ASD) after fusion surgery. The association between ASD and sagittal balance is not well understood. The purpose of this study was to investigate the biomechanical influence of various sacral slope (SS) degrees on adjacent segments after transforaminal lumbar interbody fusion (TLIF) at the L4-L5 level. METHODS: We conducted a finite element model of the L1-S1 based on computed tomography scan images. The L1-S1 model with L4-L5 TLIF was modified with various SS degrees (33°, 38°, 43°, and 48°) to investigate the biomechanical influence of SS on adjacent segments. The range of motion (ROM) and intradiscal pressure (IDP) of the adjacent segments (L3-L4 and L5-S1) were compared among models using various SS angles. RESULTS: When the SS angle increased, the ROM and IDP in L5-S1 decreased gradually after TLIF at the L4-L5 level in all motion patterns. Nevertheless, the ROM and IDP in L3-L4 were not significantly different among various SS angles. CONCLUSIONS: Decreased SS after lumbar fusion surgery may pose a higher risk of ASD. Therefore, restoring appropriate SS should be considered during decision-making prior to fusion surgery to reduce the risk of degenerative changes.

RESUMO

AIMS: The purpose of this study was to investigate the risk of additional surgery in the lumbar spine and to describe long-term changes in patient-reported outcomes after surgery for lumbar disc herniation in adolescents and young adults. PATIENTS AND METHODS: We conducted a retrospective study design on prospectively collected data from a national quality register. The 4537 patients were divided into two groups: adolescents (≤ 18 years old, n = 151) and young adults (19 to 39 years old, n = 4386). The risk of additional lumbar spine surgery was surveyed for a mean of 11.4 years (6.0 to 19.3) in all 4537 patients. Long-term patient-reported outcomes were available at a mean of 7.2 years (5.0 to 10.0) in up to 2716 patients and included satisfaction, global assessment for leg and back pain, Oswestry Disability Index, visual analogue scale for leg and back pain, EuroQol five-dimension questionnaire (EQ-5D), and 36-Item Short-Form Health Survey (SF-36) Mental Component Summary and Physical Component Summary scores. Statistical analyses were performed with Cox proportional hazard regression, chi-squared test, McNemar's test, Welch-Satterthwaite t-test, and Wilcoxon's signed-rank test. RESULTS: Any type of additional lumbar spine surgery was seen in 796 patients (18%). Surgery for lumbar disc herniation accounted for more than half of the additional surgeries. The risk of any additional surgery was 0.9 (95% confidence interval (CI) 0.6 to 1.4) and the risk of additional lumbar disc herniation surgery was 1.0 (0.6 to 1.7) in adolescents compared with the young adult group. Both age groups improved their patient-reported outcome data after surgery (all p < 0.001). Changes between short- (mean 1.9 years (1.0 to 2.0)) and long-term follow-up (mean 7.2 years (5.0 to 10.0)) were small. CONCLUSION: The risk of any additional lumbar spine surgery and additional lumbar disc herniation surgery was similar in adolescents and young adults. All patient-reported outcomes improved from preoperative to the short-term follow-up, while no likely clinically important differences between the short- and long-term follow-up were seen within both groups.

RESUMO

AIMS: Chronic low back pain due to degenerative disc disease is sometimes treated with fusion. We compared the outcome of three different fusion techniques in the Swedish Spine Register: noninstrumented posterolateral fusion (PLF), instrumented posterolateral fusion (IPLF), and interbody fusion (IBF). PATIENTS AND METHODS: A total of 2874 patients who were operated on at one or two lumbar levels were followed for a mean of 9.2 years (3.6 to 19.1) for any additional lumbar spine surgery. Patient-reported outcome data were available preoperatively (n = 2874) and at one year (n = 2274), two years (n = 1958), and a mean of 6.9 years (n = 1518) postoperatively and consisted of global assessment and visual analogue scales of leg and back pain, Oswestry Disability Index, EuroQol five-dimensional index, 36-Item Short-Form Health Survey, and satisfaction with treatment. Statistical analyses were performed with competing-risks proportional hazards regression or analysis of covariance, adjusted for baseline variables. RESULTS: The number of patients with additional surgery were 32/183 (17%) in the PLF group, 229/1256 (18%) in the IPLF group, and 439/1435 (31%) in the IBF group. With the PLF group as a reference, the hazard ratio for additional lumbar surgery was 1.16 (95% confidence interval (CI) 0.78 to 1.72) for the IPLF group and 2.13 (95% CI 1.45 to 3.12) for the IBF group. All patient-reported outcomes improved after surgery (p < 0.001) but were without statistically significant differences between the groups at the one-, two- and 6.9-year follow-ups (all p ≥ 0.12). CONCLUSION: The addition of interbody fusion to posterolateral fusion was associated with a higher risk for additional surgery and showed no advantages in patient-reported outcome Cite this article: Bone Joint J 2019;101-B:1526-1533.

RESUMO

Many studies have reported the good outcomes of percutaneous endoscopic lumbar discectomy (PELD) for the treatment of lumbar disc herniation (LDH). However, the majority of published studies on PELD showed an average hospital stay of 2 to 5 days. Thus, the purpose of this retrospective study was to evaluate and compare the clinical outcomes of patients undergoing PELD for LDH as day surgery with the outcomes of patients managed as inpatients.A total of 402 patients who underwent PELD for single-level LDH were included. The visual analog scale score (VAS) for leg and back pain, Oswestry Disability Index (ODI) score, and Macnab criteria were evaluated preoperatively and at 2 years postoperatively (final follow-up). Operation time, duration of hospital stay, cost, postoperative complications, and the rates of and reasons for delayed discharge and readmission were recorded and analyzed.The mean operative time was 45.8 ±â€Š8.4 minutes in the PELD-A (nonday surgery mode) group and 41.3 ±â€Š8.7 minutes in the PELD-D (day surgery mode) group (P = .63). The average duration of hospital stay was 2.8 ±â€Š1.1 days in the PELD-A group and 3.2 ±â€Š0.9 hours in the PELD-D group (P < .001). The average hospitalization expenses of the PELD-A and PELD-D groups were 28,090 ±â€Š286 RMB and 24,356 ±â€Š126 RMB (P = .03), respectively. In both groups, the mean VAS and ODI scores improved significantly postoperatively compared with the preoperative scores. The satisfactory result rate was 89.8% in the PELD-D group and 91.0% in the PELD-A group, without a significant difference (P = .68). The delayed discharge rate in the PELD-A and PELD-D groups was 8.20% and 8.43%, respectively (P = .93). The main reasons for delayed discharge were dysesthesia, neurologic deficit, nausea, headache and residential distance from the hospital. The overall readmission rates were 5.99% and 5.53% in the PELD-A and PELD-D groups, respectively (P = .85). The most common reasons for readmission were reherniation, sequestered herniation and pain.In conclusion, PELD is safe and effective for the treatment of LDH and can reduce medical costs as day surgery, and it thus warrants increased attention.

RESUMO

BACKGROUND: The purpose of our study is to compare the outcomes and effectiveness of MED vs OLD for lumbar disc herniation. OBJECTIVES: To identify the functional outcomes in terms of ODI score, VAS score complications in terms of intraoperative blood loss, use of general anesthesia, and morbidity in terms of total hospital stay between MED and OLD. METHODS: In our randomized prospective study we analyzed 60 patients with clinical signs and symptoms with 2 weeks of failed conservative treatment plus MRI or CT scan findings of lumbar disc herniation who underwent MED and OLD. The study was undertaken from November 2017 to January 2019 at Guangzhou Medical University of Second Affiliated Hospital, department of orthopedic surgery in spinal Unit, Guangzhou, China. Patients were divided into 2 groups i.e. who underwent MED group and the OLD group then we compared the preoperative and postoperative ODI and VAS score, duration of total hospital stay, intraoperative blood loss, and operation time. RESULTS: We evaluated 60 patients. Among them, 30 underwent MED (15 female and 15 male) and 30 underwent OLD 14 male 16 female. Surgical and anesthesia time was significantly shorter, blood loss and hospital stay were significantly reduced in patients having MED than OLD (<0.005). The improvement in the ODI in both groups was clinically significant and statistically (P < .005) at postoperative 1st day (with greater improvement in the MED group), at 6 weeks (P > .005), month 6 (>0.005) statistically no significant. The clinical improvement was similar in both groups. VAS and ODI scores improved significantly postoperatively in both groups. However, the MED group was superior to the OLD group with less time in bed, shorter operation time, less blood loss which is clinically and statistically significant (P < .05). CONCLUSIONS: The standard surgical treatment of lumbar disc herniation has been open discectomy but there has been a trend towards minimally invasive procedures. MED for lumbar spine disc herniation is a well-known but developing field, which is increasingly spreading in the last few years. The success rate of MED is about approximately 90%. Both methods are equally effective in relieving radicular pain. MED was superior in terms of total hospital stay, morbidity, and earlier return to work and anesthetic exposure, blood loss, intra-op time comparing to OLD. MED is a safe and effective alternative to conventional OLD for patients with lumbar disc herniation.

RESUMO

To evaluate the influence of various distributions of bone cement on the clinical efficacy of percutaneous kyphoplasty (PKP) in treating osteoporotic vertebrae compression fractures.A total of 201 OVCF patients (30 males and 171 females) who received PKP treatment in our hospital were enrolled in this study. According to the characteristic of cement distribution, patients were divided into 2 groups: group A ("H" shaped group), the filling pattern in vertebral body were 2 briquettes and connected with / without cement bridge; and group B ("O" shaped group), the filling pattern in vertebral body was a complete crumb and without any separation. Bone mineral density, volume of injected cement, radiographic parameters, and VAS scores were recorded and analyzed between the 2 groups.All patients finished at least a 1-year follow-up and both groups had significant improvement in radiographic parameters and clinical results. No significant differences in BMD, operation time, bleeding volume, or leakage of cement were observed between the 2 groups. Compared with group B, group A had a larger use of bone cement, lower proportion of unipedicular approach, and better VAS scores at 1 year after surgery.Both "H" and "O" shaped distribution pattern can improve radiographic data and clinical outcomes effectively. However, "H" shaped distribution can achieve better clinical recovery at short-term follow-up.

RESUMO

To compare imaging indicators and clinical effects of extreme lateral interbody fusion (XLIF) using allogenic bone, autologous bone marrow + allogenic bone, and rhBMP-2 + allogenic bone as bone graft materials in the treatment of degenerative lumbar diseases.This was a retrospective study of 93 patients with lumbar interbody fusion who underwent the extreme lateral approach from May 2016 to December 2017. According to the different bone graft materials, patients were divided into allogenic bone groups (group A, 31 cases), rhBMP-2 + allogenic bone (group B, 32 cases), and autologous bone marrow + allogenic bone (group C, 30 cases). There were no significant differences in gender, age, lesion segment, preoperative intervertebral space height, and preoperative Oswestry Dysfunction Index (ODI) and visual analogue scale (VAS) scores among the 3 groups (P > .05). Intervertebral space height, bone graft fusion rate, and ODI and VAS scores were compared immediately after surgery, and at 3, 6, and 12 months after surgery.All groups were followed up for 12 months. The intervertebral space height was significantly higher in the 3 groups immediately after surgery and at 3, 6, and 12 months after surgery, in comparison to before surgery (P < .05). There was no significant difference in the intervertebral space height among the 3 groups immediately after surgery and at 3, 6, and 12 months after surgery (P > .05). The fusion rate of group B and C was higher than that of groups A at 3, 6, and 12 months after surgery (P < .05). In the 3 groups, the VAS and ODI scores at 3, 6, and 12 months after surgery were significantly improved compared with the preoperative scores (P < .05). The VAS and ODI scores in groups B and C were significantly higher than those in group A (P < .05), but there was no significant difference between groups B and C (P > .05).The rhBMP-2 + allograft bone combination had good clinical effects and high fusion rate in XLIF.

RESUMO

RATIONALE: Lumbar degeneration-related May-Thurner syndrome (dMTS) is characterized by venous compression induced by degenerated lower lumbar structures. Treatment strategies for May-Thurner syndrome (MTS) include clearing the thrombus and correcting venous compression. Despite having different etiological factors from other MTS types, treatments for dMTS are similar, including endovascular angioplasty and continuous anticoagulation therapies. Thus, a particular treatment was designed herein to focus on compressive lumbar structures instead of intravenous management. PATIENT CONCERNS: A 59-year-old female patient with dMTS, which was induced by inferior vena cava (IVC) stenosis compressed by L4-5 anterior disc herniation. DIAGNOSIS: The patient was diagnosed with IVC stenosis and L4-5 lumbar disc herniation based on abdominal computed tomography, ultrasound, and lumbar magnetic resonance imaging findings. INTERVENTIONS: Radiofrequency thermocoagulation (RF) was applied to the patient to decrease the compression caused by anterior disc herniation. OUTCOMES: After surgery, the patient's swelling started to improve within 5 hours and completely diminished after 48 hours. Postsurgical abdominal ultrasound showed that her IVC patency increased by 20%. On follow-up, her leg symptoms did not recur at 12 months after surgery. LESSONS: We provided a novel idea in the treatment of dMTS, in which we shifted the treatment focus from endovascular patency restoration to extravascular decompression. Our case proved that RF was effective in treating dMTS, which is a complementary treatment modality to angioplasty.

RESUMO

To identify independent factors associated with prolonged hospital length of stay (LOS) in elderly patients undergoing first-time elective open posterior lumbar fusion surgery.We retrospectively analyzed the data of 303 elderly patients (age range: 60-86 years) who underwent first-time elective open lumbar posterior fusion surgery at our center from December 2012 to December 2017. Preoperative and perioperative variables were extracted and analyzed for all patients, and multivariate stepwise regression analysis was used to determine the variables affecting the LOS and important predictors of LOS prolongation (P < .001).The mean age of the patients was 67.0 ±â€Š5.5 years, and the mean LOS was 18.5 ±â€Š11.8 days, ranging from 7 to 103 days. Of the total, 166 patients (54.8%) were men and 83 patients (27.4%) had extended LOS. Multiple linear regression analysis determined that age (P < .001), preoperative waiting time ≥7 days (P < .001), pulmonary comorbidities (P = .010), and diabetes (P = .010) were preoperative factors associated with LOS prolongation. Major complications (P = .002), infectious complications (P = .001), multiple surgeries (P < .001), and surgical bleeding (P = .018) were perioperative factors associated with LOS prolongation. Age (P < .001), preoperative waiting time ≥7 days (P < .001), infectious complications (P < .001), and multiple surgeries (P < .001) were important predictors of LOS prolongation.Extended LOS after first-time elective open posterior lumbar fusion surgery in elderly patients is associated with factors including age, preoperative waiting time, infectious complications, and multiple surgeries. Surgeons should recognize and note these relevant factors while taking appropriate precautions to optimize the modifiable factors, thereby reducing the LOS as well as hospitalization costs.

RESUMO

BACKGROUND: The risk of recurrent herniation after lumbar discectomy is highest during the first postoperative year. The purpose of this study was to determine whether implantation of a bone-anchored annular closure device (ACD) following limited lumbar discectomy reduced the risk of recurrent herniation and complications during the first year of follow-up compared to limited lumbar discectomy alone (Controls) and whether this risk was influenced by patient characteristics. METHODS: In this randomized multicenter trial, patients with symptomatic lumbar disc herniation and with a large annular defect following limited lumbar discectomy were randomized to bone-anchored ACD or Control groups. The risks of symptomatic reherniation, reoperation, and device- or procedure-related serious adverse events were reported over 1 year of follow-up. RESULTS: Among 554 patients (ACD 276; Control 278), 94% returned for 1-year follow-up. Bone-anchored ACD resulted in lower risks of symptomatic reherniation (8.4% vs. 17.3%, P = .002) and reoperation (6.7% vs. 12.9%, P = .015) versus Controls. Device- or procedure-related serious adverse events through 1 year were reported in 7.1% of ACD patients and 13.9% of Controls (P = .009). No baseline patient characteristic significantly influenced these risks. CONCLUSIONS: Among patients with large annular defects following limited lumbar discectomy, additional implantation with a bone-anchored ACD lowered the risk of symptomatic reherniation and reoperation over 1 year follow-up. Device- or procedure-related serious adverse events occurred less frequently in the ACD group. These conclusions were not influenced by patient characteristics. ClinicalTrials.gov (NCT01283438).
