AbstractPosterior pedicle fixation technique is a common method for treating thoracolumbar burst fractures, but the effect of different fixation techniques on the postoperative spinal mechanical properties has not been clearly defined, especially on adjacent segments. A finite element model of T10-L2 with moderate T12 vertebra burst fracture was constructed to investigate biomechanical behavior of three posterior pedicle screw fixation techniques. Compared with traditional short-segment 4 pedicle screw fixation (TS-4) and intermediate long-segment 6 pedicle screw fixation (IL-6), mono-segment 4 pedicle screw fixation (MS-4) provides a safer surgical selection to prevent the secondary degeneration of adjacent segments in the long-term. 相似文献

Purpose
Operative treatment of unstable posterior wall fractures of acetabulum has been widely recommended. This laboratory study was undertaken to evaluate static fixation strength of three common fixation constructs: interfragmentary screws alone, in combination with conventional reconstruction plate, or locking reconstruction plate.Methods
Six formalin-preserved cadaveric pelvises were used for this investigation. A posterior wall fracture was created along an arc of 40–90 degree about the acetabular rim. Three groups of different fixation constructs (two interfragmentary screws alone; two interfragmentary screws and a conventional reconstruction plate; two interfragmentary screws and a locking reconstruction) were compared. Pelvises were axial loaded with six cycles of 1500 N. Dislocation of superior and inferior fracture site was analysed with a multidirectional ultrasonic measuring system. Results: No statistically significant difference was found at each of the superior and inferior fracture sites between the three types of fixation. In each group, the vector dislocation at superior fracture site was significantly larger than inferior one.Conclusions
All those three described fixation constructs can provide sufficient stability for posterior acetabular fractures and allow early mobilization under experimental conditions. Higher posterior acetabular fracture line, transecting the weight-bearing surface, may indicate a substantial increase in instability, and need more stable pattern of fixation. 相似文献6.

胸腰椎爆裂骨折是常见的脊柱损伤性疾病之一,其发病率、致残率较高是由胸腰段脊柱的解剖学特点所决定。国内外有多种脊柱骨折的分类,临床中使用较多的有AO分类及Denis分类,脊柱载荷分享分类现多用于评价患者是否适合于后路手术,而不能应用于评估手术指征。目前国内外胸腰椎爆裂性骨折的治疗尚无统一定式,大多数学者倾向于积极的手术治疗,其中尤以后路手术治疗为主,后路手术多采取短节段椎弓根定内固定加植骨治疗。近些年又出现了经后路270°或360°椎管减压,重建脊柱的三柱稳定性。前路及前后路联合手术都有其各自的适应症。保守治疗多采取卧床休息、体位复位、外固定支具法及功能康复等。本文总结了近年来关于胸腰椎爆裂骨折的最新治疗进展。 相似文献

ABSTRACT: BACKGROUND: To report to the orthopedic community a case of vertebral fracture and adjacent vertebral subluxation through the upper instrumented vertebra after thoracolumbar fusion with augmentation of the cranial level. METHODS: This report reviewed the patient`s medical record, her imaging studies and related literature. The possible factors contributing to this fracture are hypothesized. RESULTS: A 70-year-old woman underwent decompressive surgery and posterolateral fusion for adult lumbar scoliosis. We used pedicular screws from T10 to S1 and iliac screw at the right side, augmented with cement at T10, T11, L1, L5 and S1; and prophylactic vertebroplasty at T9 to avoid the "topping-off syndrome". Thirty days after discharge, without recognizable inciting trauma, the patient complained of pain in the lower thoracic area. The exam revealed overall neurological deficit below the level of fracture. CT scan and MRI demonstrated a T10 vertebral collapse and T9 vertebral subluxation with morphologic features of flexion-distraction fracture through the upper edge of the screw. At this point, the authors performed posterior decompression at T9 to T10 and extended posterolateral arthrodesis from T2 to T10. To our knowledge, this is an unreported fracture. CONCLUSIONS: Augmentation of the cranial level in a long thoracolumbar fusion has been developed to avoid the junctional kyphosis and compression fractures at that level. We alert the orthopedic community that this augmentation may lead to further and more severe fractures, although this opinion requires investigation for confirmation. 相似文献

Posterior wall fracture is one of the most common fracture types of the acetabulum and a conventional approach is to perform open reduction and internal fixation with a plate and screws. Percutaneous screw fixations, on the other hand, have recently gained attention due to their benefits such as less exposure and minimization of blood loss. However their biomechanical stability, especially in terms interfragmentary movement, has not been investigated thoroughly. The aims of this study are twofold: (1) to measure the interfragmentary movements in the conventional open approach with plate fixations and the percutaneous screw fixations in the acetabular fractures and compare them; and (2) to develop and validate a fast and efficient way of predicting the interfragmentary movement in percutaneous fixation of posterior wall fractures of the acetabulum using a 3D finite element (FE) model of the pelvis. Our results indicate that in single fragment fractures of the posterior wall of the acetabulum, plate fixations give superior stability to screw fixations. However screw fixations also give reasonable stability as the average gap between fragment and the bone remained less than 1 mm when the maximum load was applied. Our finite element model predicted the stability of screw fixation with good accuracy. Moreover, when the screw positions were optimized, the stability predicted by our FE model was comparable to the stability obtained by plate fixations. Our study has shown that FE modeling can be useful in examining biomechanical stability of osteosynthesis and can potentially be used in surgical planning of osteosynthesis. 相似文献

In dealing surgically with trimalleolar fracture of the ankle joint in which the comminution is not severe, the medial approach is convenient and practicable. In the process of reducing the fracture the alignment can be directly observed. The fixation of the posterior fragment is done from the front rather than from the back of the tibia, Removal of the screws used for fixation is made considerably easier. 相似文献

Spinal transpedicular fixation has gained widespread popularity in the past 5 years. In biomechanical studies, the deeply-inserted transpedicular screws withstood the largest number of cycles in the cephalad-caudad and medial-lateral direction before failure. However, in clinical practice, the risk of screw placement which is too far medially or too far laterally do exist. The optimization of increasing screw depth to avoid complication is of significant clinical importance. A Spinal Pedicle Finder (S.P.F) has been designed for transpedicular screws and a prototype has been completed. It is composed of an I-shaped body with a pair of front rails and a pair of rear rails. The front rail comprises two positioning arms that fit against the laminal bony crest, and the rear rail comprises two guiding bases that provide the transpedicular pin inserted with a specific angle. Both positioning arms and both guiding bases can be adjusted synchronously, and the specific angle over the guiding bases can be pre-set preoperatively according to the angle of pedicle axis. To date, in 7 cases (5 fracture and 2 spondylolisthesis) transpedicular screw fixation has been applied by aid of the S.P.F. Two-level fixation was applied in a fracture group and three-level fixation was applied in a spondylolisthesis group. The position of the transpedicular screw has been checked by CT scan postoperatively. A total of 32 transpedicular screws were inserted and all were in the pedicle and vertebral body except in one instances. One transpedicular screw was malpositioned on one side, partially lateral to the pedicle. However, this malposition did not cause any neurologic problem, such as dural tear, nerve root injury or other. Clinical experience has demonstrated its efficacy and safety. 相似文献

目的:研究和比较经皮椎体椎弓根固定术与开放手术治疗多椎体压缩性骨折的临床疗效及安全指标。方法:回顾性分析我科自2013.06至2015.06诊断为多椎体压缩性骨折并行内固定外科手术治疗的共计56例患者。根据手术方法的不同,分为实验组(经皮椎弓根固定组,32例)和对照组(开放手术固定组,24例)。对患者在术前即术后的各项临床指标进行随访和统计,对其VAS疼痛指标、JOA功能评分及患椎的前缘高度比进行比较。并比较两组患者的切口愈合,内固定松动等并发症。并比较两组患者的手术时间,出血量、下地时间等围手术期指标。结果:本次研究结果显示:经皮和开放椎体椎弓根固定术治疗的患者在术后及6月,12月的VAS及JOA评分中均获得了良好的改善,且两组之间并无统计学差异。在椎体前缘高度比值的比较中,术后开放组优于经皮固定组,但两者之间并无统计学差异。在并发症的比较中,经皮固定组显著优于开放手术组。在围手术期指标的比较中,经皮手术组在手术时间,出血量,下地时间等指标中都显著优于开放手术组。结论:对于多椎体压缩性骨折,经皮椎体椎弓根固定术能够达到与开放手术相似的临床治疗效果,但能够有效的减少并发症,并在手术时间,出血量,下地时间等指标中充分体现微创手术的优势。在多椎体骨折的治疗中可以进一步的进行推广。 相似文献
