Treatment of unstable thoracolumbar junction burst fractures with short- or long-segment posterior fixation in magerl type a fractures

The treatment of thoracolumbar fractures remains controversial. A review of the literature showed that short-segment posterior fixation (SSPF) alone led to a high incidence of implant failure and correction loss. The aim of this retrospective study was to compare the outcomes of the SS- and long-segment posterior fixation (LSPF) in unstable thoracolumbar junction burst fractures (T12-L2) in Magerl Type A fractures. The patients were divided into two groups according to the number of instrumented levels. Group I included 32 patients treated by SSPF (four screws: one level above and below the fracture), and Group II included 31 patients treated by LSPF (eight screws: two levels above and below the fracture). Clinical outcomes and radiological parameters (sagittal index, SI; and canal compromise, CC) were compared according to demographic features, localizations, load-sharing classification (LSC) and Magerl subgroups, statistically. The fractures with more than 10 degrees correction loss at sagittal plane were analyzed in each group. The groups were similar with regard to age, gender, LSC, SI, and CC preoperatively. The mean follow-ups were similar for both groups, 36 and 33 months, respectively. In Group II, the correction values of SI, and CC were more significant than in Group I. More than 10 degrees correction loss occurred in six of the 32 fractures in Group I and in two of the 31 patients in Group II. SSPF was found inadequate in patients with high load sharing scores. Although radiological outcomes (SI and CC remodeling) were better in Group II for all fracture types and localizations, the clinical outcomes (according to Denis functional scores) were similar except Magerl type A33 fractures. We recommend that, especially in patients, who need more mobility, with LSC point 7 or less with Magerl Type A31 and A32 fractures (LSC point 6 or less in Magerl Type A3.3) without neurological deficit, SSPF achieves adequate fixation, without implant failure and correction loss. In Magerl Type A33 fractures with LSC point 7 or more (LSC points 8-9 in Magerl Type A31 and A32) without severe neurologic deficit, LSPF is more beneficial.     

2种内固定方法治疗胸腰段椎体爆裂骨折的回顾性研究

目的 探讨短节段固定和长节段椎弓根内固定在治疗胸腰段椎体爆裂骨折的疗效。方法 回顾性分析自2006-03-2012-06行手术治疗的68例胸腰段椎体爆裂骨折的临床资料,对2组的手术时间、术中出血量、影像学指标以及脊髓功能恢复情况等进行比较。结果 65例获得随访,其中短节段固定组31例,长节段固定组34例,随访时间为12-37个月（平均18.4个月）。65例中出现断钉3例,均为短节段固定组,螺钉松动4例,其中1例为长节段固定组,3例为短节段固定组。短节段组的手术时间和术中平均出血量均要明显少于长节段组,2组间手术前后影像学指标（Cobb角、椎体前缘高度、椎管占位比）比较,差异无统计学意义（P〉0.05）。2组术后Cobb角以及椎管占位比均明显小于术前,椎体前缘高度相比术前则明显增加。2组神经功能恢复情况差异无统计学意义（P〉0.05）。结论 短节段固定与长节段椎弓根内固定治疗胸腰段椎体爆裂性骨折均能取得良好效果,短节段固定组创伤较小,但断钉或螺钉松动等并发症的发生率更高。     

Nonoperative treatment versus posterior fixation for thoracolumbar junction burst fractures without neurologic deficit

STUDY DESIGN: A prospective clinical trial was conducted. OBJECTIVE: To compare the results of nonoperative treatment versus short-segment posterior fixation using pedicle screws. SUMMARY OF BACKGROUND DATA: A previous study showed that nonoperative treatment with early mobilization produced good results, even when the posterior column was involved. METHODS: This study involved 80 patients. Inclusion criteria required the following: neurologically intact patient, single-level closed burst fracture involving T11-L2, no fracture dislocations or pedicle fractures, age of 18 to 65 years (nonpathologic adult), and no other major organ system or musculoskeletal injuries. Patients in the nonoperative group (n = 47) were allowed activity to the point of pain tolerance beginning on the day of injury using a hyperextension brace. Patients in the operative group (n = 33) underwent three-level, (one above, one at fracture level, and one below) fixation using VSP or TSRH instrumentation. The follow-up period was 2 years. RESULTS: The surgical group had less pain up to 3 months and a better Greenough Low Back Outcome Score up to 6 months, but the outcome was similar afterward. No neurologic deficit in any patient. In the nonoperative group, the kyphosis angle worsened by 4 degrees, and the retropulsion decreased from 34% to 15%. In the operative group, there was one case of superficial infection and two cases of broken screws. The kyphosis angle was improved initially by 17 degrees, but this was gradually lost. Hospital charges were four times higher in the operative group. CONCLUSIONS: Short-segment posterior fixation provides partial kyphosis correction and earlier pain relief, but the functional outcome at 2 years is similar. Early activity to the point of pain tolerance can be safely allowed.

Additional vertebral augmentation with posterior instrumentation for unstable thoracolumbar burst fractures

BackgroundTo investigate the role of vertebral augmentation in kyphosis reduction, vertebral fracture union, and correction loss after surgical management of thoracolumbar burst fracture.DesignRetrospective chart and radiographic review.SettingLevel 1 trauma center.MethodsThe analysis included patients treated between April 2007 and June 2015, who received pedicle-screw-rod distraction and reduction within two days following acute traumatic thoracolumbar burst fracture with a load sharing score >6. Medical records were retrospectively reviewed for data regarding operative details, imaging and laboratory findings, neurological function, and functional outcomes.InterventionNot applicable.Main outcome measuresSagittal index, pain score, loss of correction, and implant failure rate.ResultsNineteen patients were enrolled in this study (mean age, 37.2 ± 13 years; age range, 17–62 years; female/male ratio: 10/9). Of the five patients who received only reduction (no augmentation), one underwent revision surgery because of implant failure and pedicle screw backing out. Compared to patients who received only reduction, those who received both reduction and augmentation showed better sagittal alignment after the operation, with better sagittal index immediately postoperatively and during the follow-up (p < 0.05).ConclusionsTranspedicular vertebral augmentation with calcium sulfate/phosphate-based bone cement may reinforce thoracolumbar burst fracture stability, partially restore vertebral body height, and reduce pedicle screw bending and movement, thereby preventing early implant failure and late loss of correction, especially in patients with excellent fracture reduction.Level of evidence: Therapeutic level III, retrospective chart review     

Unstable thoracolumbar burst fractures: anterior-only versus short-segment posterior fixation

Operative management of a thoracolumbar burst fracture varies according to many factors. Fracture morphology, neurologic status, and surgeon preference play major roles in deciding upon anterior, posterior, or combined approaches. Optimizing neural decompression while providing stable internal fixation over the least number of spinal segments is the goal. Short-segment constructs via a single-stage approach (anterior versus posterior) have become viable options with advances in instrumentation and techniques. This study compares anterior-only fixation utilizing a corpectomy strut graft and a modern thoracolumbar plating system with a posterior-only construct using pedicle screws and load sharing hooks for the treatment of unstable burst fractures. Functional outcome and sagittal plane restoration and maintenance of sagittal plane alignment were evaluated. Fifty-three patients with unstable burst fractures were assessed with 40 undergoing an anterior-only construct and 13 having a short-segment posterior-only construct. The posterior-only group had no hardware failures; however, the loss of sagittal plane correction averaged 8.1 degrees, whereas the anterior-only group averaged only a 1.8-degree increase in sagittal plane kyphosis. Both techniques resulted in statistically significant initial improvement in sagittal alignment; however, the posterior short-segment group lost this statistical significance at follow-up whereas the anterior-only group continued to demonstrate statistically significant improvement in sagittal alignment at follow-up compared to preoperative measurements.     

Kyphosis recurrence after posterior short-segment fixation in thoracolumbar burst fractures

OBJECT: Recurrent kyphosis has been commonly seen after posterior short-segment pedicle instrumentation for a thoracolumbar fracture, but studies on this issue are relatively scarce, and the clinical significance of recurrent deformity is uncertain. No study has addressed the associations between the reduction of a burst fracture vertebra and the final recurrent kyphosis after implant removal. The aim of this study was to investigate the recurrent kyphosis after short-segment pedicle screw fixation in thoracolumbar burst fractures and to evaluate the effect of the degree of a vertebral reduction on the recurrent kyphotic deformity after implant removal. METHODS: Twenty-seven patients who had undergone posterior short-segment pedicle screw fixation for thoracolumbar junction burst fractures (T12-L2) were investigated retrospectively. The minimum follow-up period was 2 years (mean 2.7 years). Pain status was evaluated using the Denis pain scale. Changes in the anterior vertebral height ratio, vertebral wedge angle, upper intervertebral angle, lower intervertebral angle, Cobb angle, regional angle, and sagittal index were measured preoperatively, postoperatively, before implant removal, and at final follow-up. The correlation between the reduction of a fractured vertebra and the recurrent kyphotic deformity was also analyzed. RESULTS: After the initial surgical correction, the reduced vertebral body (VB) height (anterior vertebral height ratio and vertebral wedge angle) remained stable until final follow-up, whereas the intervertebral disc space (the upper and lower intervertebral angles) collapsed, resulting in a progressive kyphotic deformity (Cobb angle, regional angle, and sagittal index). No significant correlation was found between the final kyphosis and pain scale, but the 8 patients with a sagittal index > 15 degrees showed a higher incidence of moderate to severe pain (P3-5 on the Denis pain scale) compared with the remaining 19 patients with a sagittal index < 15 degrees . Significant positive correlation was found between recurrent kyphosis and vertebral wedge angle (r = 0.850, p < 0.001) and the reduced vertebral height (r = -0.727, p < 0.001). CONCLUSIONS: Given that the correction loss occurs primarily through disc space collapse, the amount of the final kyphotic deformity was predictable by the degree of the fractured vertebral reduction as seen on the lateral x-ray study. Surgeons who perform posterior reduction and fixation procedures should pay more attention to reducing the fractured vertebral wedge angle to its intact condition, rather than the segmental angular parameters. If the wedge angle of the fractured VB is unacceptable after reduction, additional reconstruction of the anterior column may be necessary.
