The most common site of injury to the spine is the thoracolumbar junction which is the mechanical transition junction between the rigid thoracic and the more flexible lumbar spine. The lumbar spine is another site which is more prone to injury. Absence of stabilizing articulations with the ribs, lordotic posture and more sagitally oriented facet joints are the most obvious explanations. Burst fractures of the spine account for 14% of all spinal injuries. Though common, thoracolumbar and lumbar burst fractures present a number of important treatment challenges. There has been substantial controversy related to the indications for nonoperative or operative management of these fractures. Disagreement also exists regarding the choice of the surgical approach. A large number of thoracolumbar and lumbar fractures can be treated conservatively while some fractures require surgery. Selecting an appropriate surgical option requires an in-depth understanding of the different methods of decompression, stabilization and/or fusion. Anterior surgery has the advantage of the greatest degree of canal decompression and offers the benefit of limiting the number of motion segments fused. These advantages come at the added cost of increased time for the surgery and the related morbidity of the surgical approach. Posterior surgery enjoys the advantage of being more familiar to the operating surgeons and can be an effective approach. However, the limitations of this approach include inadequate decompression, recurrence of the deformity and implant failure. Though many of the principles are the same, the treatment of low lumbar burst fractures requires some additional consideration due to the difficulty of approaching this region anteriorly. Avoiding complications of these surgeries are another important aspect and can be achieved by following an algorithmic approach to patient assessment, proper radiological examination and precision in decision-making regarding management. A detailed understanding of the mechanism of injury and their unique biomechanical propensities following various forms of treatment can help the spinal surgeon manage such patients effectively and prevent devastating complications. 相似文献

胸腰椎爆裂骨折占胸腰椎骨折的50%以上,其经常导致神经损伤和脊柱后凸畸形,对于每一种类型的骨折其治疗方法各不相同,目前应用于临床的方法有保守疗法、前路手术、后路手术、前后路联合手术及微创手术,然而最佳的治疗方法仍然是不明确的,没有一种精确的分型来指导爆裂骨折的治疗及手术方式的选择。文章综述了胸腰椎爆裂骨折的治疗进展。有研究表明无神经损伤的稳定型爆裂骨折保守治疗和手术治疗并无明显差别。伴有神经损伤的不稳定型爆裂骨折早期手术减压和稳定是应当考虑的,有研究表明对于短节段固定联合各种不同方式的椎体成形术重建前柱可以明显减少内固定失败及远期脊柱后凸畸形的发生率而受到广大脊柱外科医生的推崇。按照生物力学原理及考虑到患者固定节段后相邻节段退变的发生,非融合技术已逐渐应用于临床,其远期疗效尚需进一步研究证实。 相似文献

Purpose:
The purpose of this prospective study is to investigate the relationship between the functional outcome and the radiographic results of conservatively treated two-, three- and four-part proximal humeral fractures in patients aged over 65 years.Materials and Methods:
The study comprised 29 prospectively followed cases aged over 65 years who presented with displaced proximal humerus fracture between 2009 and 2011. The fractures were classified according to the Neer classification and all met the displacement criteria described by Neer. Standard physical therapy program was applied. Patients were evaluated clinically using Constant shoulder score, quick form of disabilities of arm, shoulder and hand score and visual analog scale. At the final follow-up, humeral head position in the coronal plane was assessed with neck-shaft angle. Any complication was recorded during the treatment period. Correlation between the functional outcomes and final radiologic results were statistically analyzed.Results:
Data were analyzed from 29 cases (21 female, 8 male) with a mean age was 78 ± 8.6 years (range 65-93 years). The mean follow-up period was 18.2 ± 4.07 months (range 12-26 months). Functional results were significantly related with initial fragmentation. However, there was no correlation between the functional outcomes and the final geometry of the humeral head. Despite the union occurred with deformity, the functional outcome were satisfactory.Conclusion:
The results of this study show that initial fragmentation has a negative effect on the functional results. However, the changed position of the humeral head on coronal plane does not affect the final functional results. 相似文献4.

Near-anatomical reduction and stabilization of burst fractures of the lower thoracic or lumbar spine
Summary Thirty-one consecutive symptomatic patients with burst fractures of the lower thoracic or lumbar spine (T11-L4) were treated by early surgery in a 36-month period, with near-anatomical reduction being achieved via the postero-lateral route. Fusion and reconstruction of the vertebral body was done by using autologous or processed bovine bone. Correction of the kyphotic deformity was obtained by using distraction rods or transpedicular devices. The post-operative mean degree of kyphosis, percent vertebral height, and percent canal stenosis showed statistically significant differences, compared with the corresponding pre-operative mean values. All but one of the 25 patiens with incomplete paraplegia exhibited neurological improvement, with complete recovery occurring in 20 cases (median followup: 16 months) irrespective of the location of the lesion at the thoraco-lumbar junction (T11-L1) or the lower lumbar segment (L2-L4). Out of the 6 patients with pre-operative complete paraplegia, useful motor power returned in one case with a lesion below L1.The results confirm the suitability of the postero-lateral route and are consistent with the assumption that early near-anatomical reduction and stabilization favours maximum neurological recovery in symptomatic patients. 相似文献

Background:
Short-segment fixation alone to treat thoracolumbar burst fractures is common but it has a 20-50% incidence of implant failure and rekyphosis. A transpedicle body augmenter (TpBA) to reinforce the vertebral body via posterior approach has been reported to prevent implant failure and increase the clinical success rate in treating burst fracture. This article is to evaluate the longterm results of short-segment fixation with TpBA for treatment of thoracolumbar burst fractures.Materials and Methods:
Patients included in the study had a single-level burst fracture involving T11-L2 and no distraction or rotation element with limited neurological deficit. Patients in the control group (n = 42) were treated with short-segment posterior instrumentation alone, whereas patients in the augmented group (n = 90) were treated with a titanium spacer designed for transpedicle body reconstruction. The followup was 48-101 months. The radiographic and clinical results were evaluated and compared by Student''s t test and Fisher''s exact test.Results:
The blood loss, operation time and hospitalization were similar in both the groups. The immediate postoperative anterior vertebral restoration rate of the augmented group was similar to that of the control group (97.6% ± 2.4% vs. 96.6% ± 3.2%). The final anterior vertebral restoration was greater in the augmented group than in the control group (93.3% ± 3.4% vs. 62.5% ± 11.2%). Immediate postoperative kyphotic angles were not significantly different between the groups (3.0° ± 1.8° vs. 5.1° ± 2.3°). The final kyphotic angles were less in the augmented group than the control group (7.3° ± 3.5° vs. 20.1° ± 5.4°). The augmented group had less (P < 0.001) implant failure [0% (n=0) vs. 23.8% (n=10)] for the control group) and more patients (P < 0.001) with no pain or minimal or occasional pain (Grade P1 or P2) than the control group [90.0% (n=81) vs. 66.7% (n=28)]. All patients in the augmented group and 39 (92.8%) patients in the control group experienced neurological recovery to Frankel Grade E. Three patients in the control group had improvement to Frankel Grade D from Frankel Grade C, but later had deterioration to Frankel Grade C because of loosening and dislodgement of the implant.Conclusion:
Posterior body reconstruction with TpBA can maintain kyphosis correction and vertebral restoration, prevent implant failure and lead to better clinical results. 相似文献14.
To assess the efficacy and feasibility of vertebroplasty and posterior short-segment pedicle screw fixation for the treatment
of traumatic lumbar burst fractures. Short-segment pedicle screw instrumentation is a well described technique to reduce and
stabilize thoracic and lumbar spine fractures. It is relatively a easy procedure but can only indirectly reduce a fractured
vertebral body, and the means of augmenting the anterior column are limited. Hardware failure and a loss of reduction are
recognized complications caused by insufficient anterior column support. Patients with traumatic lumbar burst fractures without
neurologic deficits were included. After a short segment posterior reduction and fixation, bilateral transpedicular reduction
of the endplate was performed using a balloon, and polymethyl methacrylate cement was injected. Pre-operative and post-operative
central and anterior heights were assessed with radiographs and MRI. Sixteen patients underwent this procedure, and a substantial
reduction of the endplates could be achieved with the technique. All patients recovered uneventfully, and the neurologic examination
revealed no deficits. The post-operative radiographs and magnetic resonance images demonstrated a good fracture reduction
and filling of the bone defect without unwarranted bone displacement. The central and anterior height of the vertebral body
could be restored to 72 and 82% of the estimated intact height, respectively. Complications were cement leakage in three cases
without clinical implications and one superficial wound infection. Posterior short-segment pedicle fixation in conjunction
with balloon vertebroplasty seems to be a feasible option in the management of lumbar burst fractures, thereby addressing
all the three columns through a single approach. Although cement leakage occurred but had no clinical consequences or neurological
deficit. 相似文献

The analysis of the variables,affecting outcome in surgically treated tibia pilon fractured patients
Introduction
Treatment of tibia pilon fractures is challenging. Outcome after tibia pilon fractures depend on multiple factors. Aim of this study is to evaluate the potential variables that are known to affect the outcome after tibia pilon fractures.Patients and methods
Forty patients with 42 tibia pilon fractures with a one-year follow-up, who had undergone surgical treatment between January 2007 and June 2011, were evaluated, retrospectively. Patients were divided into 3 groups regarding the choice of surgical treatment (Group A-22 patients treated with open reduction-internal fixation; Group B-9 patients treated with mini-open reduction-internal fixation and external fixation; and Group C-11 patients treated with closed reduction-external fixation). Fractures were classified using Müller-AO and Rüedi/Allgöwer classifications. Quality of reduction was evaluated using Ovadia and Beals’ criteria. All patients underwent functional assessment using AOFAS ankle-hindfoot scale and Teeny–Wiss scoring system at the last follow-up.Results
Mean age of the patients was 49 (20–80). There were eight 43-B3, six 43-C1, twelve 43-C2 and sixteen 43-C3 fractures according to Müller-AO classification and ten type 1, ten type 2 and twenty two type 3 fractures according to Rüedi/Allgöwer classification. There were 15 (35.7%) open fractures. No statistically significant relation was found between quality of reduction and type of surgery. Also no significant relation was found between the type of surgery and functional scores. No significant correlation was found between functional scores and Müller-AO classification, but functional scores were found significantly worse in Rüedi/Allgöwer type 3 fractures. Functional scores were found significantly related to the quality of reduction. Early complications were seen in 22 and late complications were seen in 9 fractures. No statistically significant relation was found between complications, type of surgery and functional scores.Conclusion
The most important factor affecting outcome in surgically treated tibia pilon fractures was quality of reduction. Poor functional scores were found independent from the type of surgery and quality of reduction in Rüedi/Allgöwer type 3 fractures, which was characterized with articular surface comminution and metaphyseal impaction. 相似文献16.

BACKGROUND CONTEXT: Several studies report a favorable short-term outcome after nonoperatively treated two-column thoracic or lumbar burst fractures in patients without neurological deficits. Few reports have described the long-term clinical and radiological outcome after these fractures, and none have, to our knowledge, specifically evaluated the long-term outcome of the discs adjacent to the fractured vertebra, often damaged at injury and possibly at an increased risk of height reduction and degeneration with subsequent chronic back pain. PURPOSE: To evaluate the long-term clinical and radiological outcome after nonoperatively treated thoracic or lumbar burst fractures in adults, with special attention to posttraumatic radiological disc height reduction. STUDY DESIGN: Case series. PATIENT SAMPLE: Sixteen men with a mean age of 31 years (range, 19-44) and 11 women with a mean age of 40 years (range, 23-61) had sustained a thoracic or lumbar burst fracture during the years 1965 to 1973. Four had sustained a burst fracture Denis type A, 18 a Denis type B, 1 a Denis type C, and 4 a Denis type E. Seven of these patients had neurological deficits at injury, all retrospectively classified as Frankel D. OUTCOME MEASURES: The clinical outcome was evaluated subjectively with Oswestry score and questions regarding work capacity and objectively with the Frankel scale. The radiological outcome was evaluated with measurements of local kyphosis over the fractured segment, ratios of anterior and posterior vertebral body heights, adjacent disc heights, pedicle widths, sagittal width of the spinal canal, and lateral and anteroposterior displacement. METHODS: From the radiographical archives of an emergency hospital, all patients with a nonoperatively treated thoracic or lumbar burst fracture during the years 1965 to 1973 were registered. The fracture type, localization, primary treatment, and outcome were evaluated from the old radiographs, referrals, and reports. Twenty-seven individuals were clinically and radiologically evaluated a mean of 27 years (range, 23-41) after the injury. RESULTS: At follow-up, 21 former patients reported no or minimal back pain or disability (Oswestry Score mean 4; range, 0-16), whereas 6 former patients (of whom 3 were classified as Frankel D at baseline) reported moderate or severe disability (Oswestry Score mean 39; range, 26-54). Six former patients were classified as Frankel D, and the rest as Frankel E. Local kyphosis had increased by a mean of 3 degrees (p<.05), whereas the discs adjacent to the fractured vertebrae remained unchanged in height during the follow-up. CONCLUSIONS: Nonoperatively treated burst fractures of the thoracic or lumbar spine in adults with or without minor neurological deficits have a predominantly favorable long-term outcome, and there seems to be no increased risk for subsequent disc height reduction in the adjacent discs. 相似文献
