背景:骨折的愈合除了与骨折类型、骨折局部血运及感染等因素有关之外,还与内固定物的选择、使用及规范操作有着很大的关系。
目的:分析不同植入物内固定治疗四肢骨折后出现骨不连的原因,并探讨有效的治疗方法及合适的内固定物选择方案。
方法:由第一作者采用电子检索的方式,在万方数据库(http://www.wanfangdata.com.cn/)中检索2000-01/2010-05有关骨折内固定后骨不连及治疗骨不连的研究文章,关键词为“骨折,内固定,骨不连”。排除重复研究或Meta分析类文章,筛选纳入25篇文献进行深入分析。
结果与结论:四肢骨折内固定后骨不连的发生率除了与骨折类型、骨折断端血运以及感染等因素有关之外,还与操作技术,尤其是内固定物选择以及内固定的使用方式有直接关系。对于许多骨折,如何针对骨折的类型,选择合适的内固定物以及准确的操作技术是维持内固定物长久有效性、促进骨折愈合的重要因素。虽然由于受伤机制的不同,四肢骨折会有许多复杂的类型,并对骨折愈合有一定的影响,但随着骨折内固定材料的不断推陈出新,对不同部位、不同类型的骨折有着越来越多针对性的固定方式。内固定物的选择及使用方式的准确与否,对于骨折内固定后的愈合有着很大的影响。 相似文献

背景:为了恢复关节的功能,移位的旋后外旋型踝关节骨折常常需要切开复位内固定。老年人由于存在骨质疏松,实施内固定存在一定困难,而且容易出现伤口并发症。
目的:探讨老年移位的踝关节旋后外旋骨折手术治疗方式及内固定物的选择。
方法:选择北京大学第一医院骨科收治的移位踝关节旋后外旋型骨折患者128例,其中单纯外踝骨折29例,双踝骨折52例,三踝骨折47例。外踝选用前外侧切口98例,后外侧切口30例;后侧防滑接骨板固定6例,加压螺钉与中和接骨板固定122例(其中1/3管状接骨板98例,锁定接骨板24例);内踝骨折均使用空心加压螺钉固定;后踝骨折通过后外侧切口复位固定24例。术后根据骨折稳定情况,选择是否使用石膏外固定。随访时,根据X射线平片评估骨折愈合情况,采用Olerud and Molander评分系统进行评定。
结果与结论:128例患者均获得随访,随访时间12~25个月,骨折均愈合。外踝伤口延迟愈合5例(4%),其中锁定接骨板固定者3例、1/3管状板2例,两者间差异无显著性意义(P > 0.05)。无深部感染发生。骨折愈合后关节功能评分优55例,良61例,可10例,差2例,优良率91%。骨折愈合后,因局部不适取出内固定物31例,其中管状接骨板19例,锁定接骨板12例,两者相比,差异有显著性意义(P < 0.05)。在取出的12例锁定接骨板中,2例(17%)发生螺钉与接骨板间的“冷焊接”。1例防滑接骨板固定后出现腓骨肌腱炎,保守治疗后疼痛缓解。提示针对老年人移位的踝关节旋后外旋型骨折,合理选用手术入路和内固定物有利于减少伤口的并发症,解剖复位和良好的内固定有利于骨折恢复。 相似文献

背景:C2/3椎间盘切除,钢板置入内固定加椎间植骨是治疗Hangman骨折的常用术式。该术式在临床应用广泛,但目前尚缺乏相关实验评价钢板置入内固定治疗Hangman骨折的生物力学特点研究。
目的:评价钢板置入内固定+椎间植骨治疗Ⅱ型Hangman骨折的生物力学稳定性。
方法:6具正常成人新鲜冷冻颈椎,每一标本依次制作成以下3种状态组:即正常对照组、Ⅱ型Hangman骨折模型组、椎间植骨+钢板内固定组。按以上顺序应用脊柱三维运动试验机和三维激光扫描仪测试每一状态C2/3节段的三维运动范围。
结果与结论:与正常对照组比较,Ⅱ型Hangman骨折模型组C2/3节段前屈、后伸、旋转及侧弯关节活动度均显著增大(P < 0.05),钢板内固定+椎间植骨组旋转方向关节活动度显著增大(P < 0.05);与Ⅱ型Hangman骨折模型组相比,钢板内固定+椎间植骨组C2/3节段前屈、后伸及侧弯关节活动度均显著减小(P < 0.05)。结果提示钢板置入内固定能够在前屈、后伸及侧弯方向恢复Ⅱ型Hangman骨折的稳定性,然而在旋转方向缺乏稳定作用,术后需辅以外固定以确保融合。 相似文献

Esophageal injury after anterior cervical discectomy and fusion (ACDF) is a rare complication that can be life threatening. The sternocleidomastoid (SCM) pedicled muscle flap has emerged as an effective and versatile tool for selected esophageal perforations. The authors report their surgical experience in three patients with an esophageal perforation after ACDF, and the steps taken to achieve successful repair using a SCM muscle flap. All three patients underwent ACDF at another hospital. Postoperatively, patients complained of severe dysphagia, neck swelling, fever, and alimentary fluid leakage. They were later referred to the author’s hospital for diagnostic evaluation and surgical treatment of an esophageal perforation. Esophageal perforation was diagnosed on esophagoscopy and esophagography, and treated by primary closure using an SCM muscle flap. Postoperatively, all patients had a good result. Surgery-related complications occurred in one patient with dysfunction of the recurrent laryngeal nerve. This study shows that esophagoscopic diagnosis and surgical treatment using a SCM muscle flap is highly effective in patients with an esophageal perforation related to ACDF. 相似文献

We analyzed the clinical efficacy of the Zero-P implant (Synthes GmbH Switzerland, Oberdorf, Switzerland) in the treatment of single level cervical spondylotic myelopathy. The clinical data of 47 patients with single level cervical spondylotic myelopathy were retrospectively analyzed. Twenty-two patients were treated with a Zero-P implant (Group A) and 25 with a titanium plate with cage (Group B) between January 2009 and September 2010. Operative time, intraoperative blood loss, preoperative and postoperative Japanese Orthopaedic Association (JOA) scores and JOA recovery rate, dysphagia incidence and adjacent segment degeneration rate were measured. The mean operative time in Group A and Group B was 98.18 minutes and 105.4 minutes, respectively. The average intraoperative blood loss in Group A and Group B was 87.95 ml and 92.4 ml, respectively. There were no statistical differences in operation time and intraoperative blood loss between the two groups (p > 0.05). The JOA score was significantly improved in the two groups (p < 0.001), and the recovery rate was similar (60.86% for Group A versus 62.95% for Group B, p > 0.05). Dysphagia was experienced by one (4.5%) patient in Group A and eight (32%) patients in Group B, which was significantly different (p = 0.044). There was no statistical significance found in the adjacent level degeneration rates between Group A and Group B (p = 0.330). The Zero-P implant and traditional titanium plate with cage are effective treatments for single level cervical spondylotic myelopathy, but the Zero-P implant has a lower dysphagia incidence. 相似文献

The primary aim of this study was to conduct a systematic review of reports of patients with cervical spondylotic myelopathy and to assess the value of intraoperative monitoring (IOM), including somatosensory evoked potentials, transcranial motor evoked potentials and electromyography, in anterior cervical procedures. A search was conducted to collect a small database of relevant papers using key words describing disorders and procedures of interest. The database was then shortlisted using selection criteria and data was extracted to identify complications as a result of anterior cervical procedures for cervical spondylotic myelopathy and outcome analysis on a continuous scale. In the 22 studies that matched the screening criteria, only two involved the use of IOM. The average sample size was 173 patients. In procedures done without IOM a mean change in Japanese Orthopaedic Association score of 3.94 points and Nurick score by 1.20 points (both less severe post-operatively) was observed. Within our sub-group analysis, worsening myelopathy and/or quadriplegia was seen in 2.71% of patients for studies without IOM and 0.91% of patients for studies with IOM. Variations persist in the existing literature in the evaluation of complications associated with anterior cervical spinal procedures. Based on the review of published studies, sufficient evidence does not exist to make recommendations regarding the use of different IOM modalities to reduce neurological complications during anterior cervical procedures. However, future studies with objective measures of neurological deficits using a specific IOM modality may establish it as an effective and reliable indicator of injury during such surgeries. 相似文献

The aim of this study is to evaluate an integrated cage and plate device (the plate cage Benezech, PCB) filled with autogenous bone in anterior cervical discectomy and fusion. The fused segment height, lordosis, and fusion were assessed by postoperative radiographic examination at different intervals. Patients were evaluated using Odom’s criteria and the Short Form (SF)-36 Health Survey questionnaire. The mean follow-up duration was 4.1 years. Fusion was achieved in 90.0%, 96.0% and 100% of patients at 3 months, 6 months and at final visit, respectively. The fused segment height and lordosis were restored and maintained. Cage subsidence (3 mm) occurred at one level and settling was observed at three levels. An excellent-to-good result was achieved in 81.8% of patients. The data from the SF-36 questionnaire revealed significant postoperative improvement (p < 0.01) except for social function and mental health. This study suggests that patients instrumented with PCB can obtain good radiographic and clinical results and that PCB is a safe and effective device in cervical anterior fusion. 相似文献

IntroductionMultilevel cervical pathology may be treated via combined anterior cervical decompression and fusion (ACDF) followed by posterior spinal instrumented fusion (PSIF) crossing the cervico-thoracic junction.The purpose of the study was to compare perioperative complication rates following staged versus same day ACDF combined with PSIF crossing the cervico-thoracic junction.Material and methodsA retrospective review of consecutive patients undergoing ACDF followed by PSIF crossing the cervico-thoracic junction at a single institution was performed.Patients underwent either same day (group A) or staged with one week interval surgeries (group B). The minimum follow-up was 12 months.ResultsThirty-five patients (14 females and 21 males) were analyzed. The average age was 60 years (37–82 years). There were 12 patients in group A and 23 in group B. Twenty-eight complications noted in 14 patients (40%) included: dysphagia in 13 (37%), dysphonia in 6 (17%), post-operative reintubation in 4 (11%), vocal cords paralysis, delirium, superficial incisional infection and cerebrospinal fluid leakage each in one case. Significant differences comparing group A vs. B were found in: the number of levels fused posteriorly (5 vs. 7; p = 0.002), total amount of intravenous fluids (3233 ml vs. 4683 ml; p = 0.03), length of hospital stay (10 vs. 18 days; p = 0.03) and transfusion of blood products (0 vs. 9 patients). Smoking and cervical myelopathy were the most important risk factors for perioperative complications regardless of the group.ConclusionsStaging anterior cervical decompression and fusion with posterior cervical instrumented fusion 1 week apart does not decrease the incidence of perioperative complications. 相似文献

Pseudarthrosis occurs after approximately 2–20% of anterior cervical discectomy and fusion (ACDF) procedures; it is unclear if posterior or anterior revision should be pursued. In this study, we retrospectively evaluate the outcomes in 22 patients with pseudarthrosis following ACDF and revision via posterior cervical fusion (PCF). Baseline demographics, preoperative symptoms, operative data, time to fusion failure, symptoms of pseudarthrosis, and revision method were assessed. Fusion outcome and clinical outcome were determined at last follow-up (LFU). Thirteen females (59%) and 9 (41%) males experienced pseudarthrosis at a median of 11 (range: 3–151) months after ACDF. Median age at index surgery was 51 (range: 33–67) years. All patients with pseudarthrosis presented with progressive neck pain, with median visual analog scale (VAS) score of 8 (range: 0–10), and/or myeloradiculopathy. Patients with pseudarthrosis <12 months compared to >12 months after index surgery were older (p = 0.013), had more frequent preoperative neurological deficits (p = 0.064), and lower baseline VAS scores (p = 0.006). Fusion was successful after PCF in all patients, with median time to fusion of 10 (range: 2–14) months. Eighteen patients fused both anteriorly and posteriorly, two patients fused anteriorly only, and two patients fused posteriorly only. Median VAS neck score at LFU significantly improved from the time of pseudarthrosis (p = 0.012). While uncommon, pseudarthrosis may occur after ACDF. All patients achieved successful fusion after subsequent posterior cervical fusion, with 91% fusing a previous anterior pseudarthrosis after posterior stabilization. Neck pain significantly improved by LFU in the majority of patients in this study. 相似文献
