背景:中老年人的颈椎可因不同原因导致不同程度的椎管狭窄,在受伤时发生无骨折脱位颈髓损伤概率也相对较高,有文献报道可占颈段脊髓损伤的3%-16%。目的:探讨MRI在诊断和预测无骨折脱位型颈脊髓损伤预后中的作用,并分析手术效果的影响因素。方法:回顾分析2014年8月至2016年6月就诊于淄博市中心医院的51例成人无骨折脱位型颈脊髓损伤患者,根据影像学资料,分别采取前路、后路或前-后路联合手术,将术中所见颈椎骨韧带损伤与MRI表现对比。使用单因素和多因素Logistic回归分析患者的年龄、外伤类别、脊髓损伤MRI类型、受伤到就诊时间、脊髓损伤信号长度、脊髓损伤ASIA分级、颈椎管狭窄程度、伤后8 h内是否使用激素治疗、受伤至手术的时间、手术方式等10个因素对预后的影响。结果与结论:(1)颈椎MRI较术中所见更全面显示了脊髓及椎间盘韧带复合体损伤(χ~2=5.966,P<0.05),且颈脊髓损伤与相应椎间隙平面椎间盘韧带复合体损伤有关(χ~2=1.53,P<0.05);(2)单因素分析结果表明,脊髓损伤MRI类型、脊髓损伤信号长度、脊髓损伤ASIA分级、颈椎管狭窄程度、伤后8 h内是否使用激素治疗、受伤至手术时间与脊髓神经功能恢复相关(P<0.1);(3)再经多因素Logistic回归分析,脊髓损伤MRI类型、脊髓损伤信号长度、颈椎管狭窄程度、受伤至手术时间与脊髓神经功能恢复有明显相关性(P<0.05);(4)结果提示,颈椎MRI因其组织分辨优势,在诊断无骨折脱位型颈脊髓损伤及预测其预后中具有重要作用;脊髓损伤程度、颈椎管狭窄程度及手术时机是影响术后疗效的主要因素。     

钛合金板置入内固定修复老年肱骨远端骨折的生物相容性

BACKGROUND: Fracture of the distal humerus is a common type of fracture. Conservative treatment or metal implant fixation can be used during the clinical treatment of elderly patients, but the choice of specific treatment options still lacks of clear conclusion. OBJECTIVE: To explore the clinical repair effect and biocompatibility of titanium alloy implant internal fixation for aged patients with distal humeral fractures. METHODS: A total of 41 elderly patients with humeral fractures, who were hospitalized in Danzhou Municipal First People’s Hospital from July 2011 to July 2014, were enrolled in this study. In accordance with the wishes of patients, repair program was selected. 22 patients in the control group received conservative treatment. 19 patients in the observation group received titanium alloy implant fixation. After 12 months of follow-up, elbow joint activity, elbow joint function recovery and adverse reactions were observed and compared in the two groups. RESULTS AND CONCLUSION: After conservative treatment and internal fixation, each index score and total score of range of motion of shoulder joint were significantly higher in the two groups as compared with pre-treatment (P < 0.05). Each index score and total score were significantly higher in the observation group than in the control group (P < 0.05). Curative effect evaluation results showed four excellent patients and three good patients in the control group, eight excellent patients and four good patients in the observation group. The excellent and good rate was significantly lower in the control group than in the observation group (P < 0.05). Two patients suffered from mild inflammatory hyperplasia during taking out the fixator in the observation group, and the remaining patients did not affect inflammatory hyperplasia or capsular tissue. In the observation group, after surgery, one case experienced numbness of the ulnar nerve, which disappeared after treatment with trophic nerve. One case suffered from wound infection, which was controlled by antibiotic treatment, and did not induce a serious outcome. After follow-up, none of them had nonunion or internal fixation loosening. The results show that titanium alloy implant fixation for the treatment of distal humerus fractures can get better repair effect compared with conservative treatment, can effectively improve the elbow joint function, and titanium alloy material has good biocompatibility.      

植骨融合内固定修复连续双节段颈椎间盘突出症：钛网与椎间融合器的比较

BACKGROUND: Many studies have shown that different types of anterior cervical surgery in the treatment of two-level contiguous cervical disc herniation can obtain satisfactory results, but which method is the best has not yet reached a consensus. OBJECTIVE: To compare the efficacy and safety of three types of anterior cervical surgery for treating two-level contiguous cervical disc herniation.  METHODS: We retrospectively analyzed clinical data of 62 patients with two-level contiguous cervical disc herniation who underwent anterior decompression and fusion. These patients were assigned to three groups. Bone graft group received anterior cervical discectomy with autogenous iliac bone graft fusion. Titanium mesh group received anterior cervical corpectomy with titanium mesh fusion. Cage group received anterior cervical discectomy with cage fusion. Fusion rate of bone graft and improvement of neurological function (Japanese Orthopaedic Association Scores) were evaluated and compared after treatment in the three groups. Cervical vertebra anteroposterior and lateral images were used to measure height of anterior and posterior margin of vertebral body and Cobb angle changes of fusion segment. RESULTS AND CONCLUSION: All 62 patients were followed up and the follow-up time was ranged from 8 to 30 months. Operation time was significantly longer in the bone graft group than in the titanium mesh and Cage groups (P < 0.05). Intraoperative blood loss was larger in the bone graft group than in the titanium mesh and Cage groups (P < 0.05). Japanese Orthopaedic Association Scores were significantly improved after treatment (P < 0.05). No significant difference was found at different time points (P > 0.05). The fusion rate of bone graft was higher in the bone graft group than in the titanium mesh and Cage groups (P < 0.05) at 3 months after treatment, and bone union was found in the final follow-up. Height of anterior and posterior margin of vertebral body was significantly increased after treatment (P < 0.05). No significant difference in the increase of the height of anterior margin was detected among the three groups (P > 0.05). The increase in the height of posterior margin was higher in the Cage group than in the bone graft group and titanium mesh group (P < 0.05). Vertebral height loss of the anterior margin was higher in the bone graft group than in the titanium mesh and Cage groups, but vertebral height loss of the posterior margin was highest in the bone graft group, followed by titanium mesh group and Cage group at 3 months after treatment (P < 0.05). The increase value of Cobb angle was higher in the titanium mesh group than in the bone graft group and Cage group (P < 0.05). At 3 months after treatment, the altered value of Cobb angle was highest in the bone graft group, followed by titanium mesh group and Cage group (P < 0.05). No significant difference in the height of anterior and posterior margins of the vertebral body and Cobb angle was detectable between final follow-up and 3 months post-treatment (P > 0.05). These findings indicated that the three kinds of fusion method for treating two-level contiguous cervical disc herniation could obviously lessen nervous systems and improve cervical vertebra functions. In the bone graft group, operation time was long. Intraoperative blood loss was more. Postoperative height loss of the posterior margin of the vertebral body was visible. Cervical lordosis could be easily induced. Compared with the bone graft group, titanium mesh and Cage groups could better maintain the height and curvature of the cervical vertebra, but the Cage group had apparent advantages.  中国组织工程研究杂志出版内容重点：人工关节;骨植入物;脊柱;骨折;内固定;数字化骨科;组织工程

浮肩损伤植入物固定方案选择与骨折移位的关系

BACKGROUND: There are more literature reports about the floating shoulder injury in recent years, but there still have obvious controversies about the treatment of the floating shoulder injury. Whether choose the conservative treatment or operative treatment is an important issue in face of every clinician. OBJECTIVE: To review the clinical features and present treatment situation of the floating shoulder injury. METHODS: A computer-based online search was performed in the PubMed and the China National Knowledge Infrastructure database for the clinical research papers on the treatment methods of the floating shoulder injury from January 1975 to August 2015. The key words were floating shoulder injury, diagnose, treatment method. The articles published earlier and repetitive researches were excluded. Finally, 33 articles were included for further analysis. RESULTS AND CONCLUSION: (1) Floating shoulder injury is a kind of severe shoulder injury which is caused by high energy and violence. It is often complicated with severe systemic injury, which should be paid more attention in clinic. (2) The treatment of floating shoulder injury has been controversial, and there is no standard treatment guideline. Conservative treatment and operative treatment can get good outcomes. There are less reports about conservative treatment of the floating shoulder injury in recent years. The outcome of operative treatment may better than conservative treatment. (3) Conservative or simple clavicle fixation can be used for fractures without displacement or with small displacement. Obviously displaced fractures can be treated with simple clavicle fixation or double fixation of clavicle and scapula, which may have good repair effects.

背景：近年来微创技术理念越来越受到重视,一些新的微创方法被运用到脊柱骨折治疗中,对旧的开放式手术治疗方法提出了挑战。 目的：对比观察常规后路开放经伤椎椎弓根螺钉内固定、微创内固定方式(利用Quadrant通道内固定和经皮Sextant内固定)治疗单节段无神经症状胸腰椎骨折的临床疗效。 方法：纳入2012年1月至2013年1月于柳州市工人医院脊柱外科住院并接受内固定修复治疗的94例单节段无神经症状胸腰椎骨折患者,根据患者病情及意愿分为开放内固定组、Quadrant通道内固定组及经皮Sextant内固定组,观察并比较各组患者的围手术期参数、临床疗效及影像学检查指标。 结果与结论：Quadrant通道内固定组、经皮Sextant内固定组在术中出血量、手术切口长度、住院时间方面均优于常规后路开放内固定组(P < 0.05)。94例患者均获得随访,随访时间为6个月,无脱钉、断钉及神经损伤现象。3组伤椎内固定后椎体前缘高度、Cobbs角、矢状位指数与内固定前相比较均有明显改善(P < 0.05),但3组之间比较差异无显著性意义(P > 0.05)。两微创组内固定后目测类比评分、Oswestry功能障碍指数均优于常规开放内固定组(P < 0.05)。提示与传统的开放内固定相比,微创(经皮Sextant内固定及利用Quadrant通道内固定)治疗胸腰椎骨折不仅能取得与之相当的影像学效果,而且具有创伤小、出血少、恢复快、安全性高的优点,有更好的临床疗效。在严格掌握手术适应证情况下,微创方法是治疗无神经损伤胸腰椎骨折的理想选择。中国组织工程研究杂志出版内容重点：人工关节;骨植入物;脊柱;骨折;内固定;数字化骨科;组织工程全文链接：     

微创后路经皮椎弓根螺钉内固定修复单纯前中柱损伤的急性胸腰椎骨折：回顾性、自身前后对照临床试验方案

BACKGROUND: Posterior pedicle screw fixation is commonly used for thoracolumbar fracture. However, associated disadvantages include severe trauma, extensive bleeding, long rehabilitation time, and long postoperative duration of intractable lumbar stiffness and low back pain. Percutaneous pedicle screw external fixation can reduce injury caused by screw insertion into the paraspinal muscles; particularly in acute thoracolumbar vertebral compression fracture with simple anterior spinal column injury. We hypothesized that minimally invasive posterior percutaneous pedicle screw fixation for acute thoracolumbar vertebral fractures with simple anterior spinal column injury would exhibit good curative effects.

经皮椎弓根螺钉内固定修复单节段胸腰椎骨折：活动度改善12个月随访

BACKGROUND: Studies have shown that percutaneous pedicle screw internal fixation in repair of single segment of thoracolumbar fracture can overcome quadrilateral effect, get better biomechanical properties, meanwhile, it also can provide three-point fixation, reduce suspension effect, and reduce the formation of kyphosis. OBJECTIVE: To investigate the clinical efficacy and incidence of complications of the percutaneous pedicle screw internal fixation for treatment of single segment thoracolumbar fractures. METHODS: Totally 36 patients with single segment thoracolumbar fractures treated by percutaneous pedicle screw internal fixation were enrolled. A total of 36 vertebral bodies were treated: T11=5, T12=8, L1=17, L2=6. The visual analog scale scores before treatment and at 3, 6 and 12 months after treatment, the Oswestry disability indexes before treatment, at the first week and at the 12th month after treatment, the Cobb angle before treatment, the first day and at the 12th month after treatment were compared and observed. The incidence of complications was recorded. RESULTS AND CONCLUSION: The visual analog scale scores at 3, 6 and 12 months after treatment was significantly lower than those before treatment (P < 0.001). The Oswestry disability indexes before treatment, at the first week and at the 12th month after treatment were significantly lower those that before treatment (P < 0.001).The Cobb angle before treatment, at the first day and at the 12th month after treatment was significantly smaller than that before treatment (P < 0.001). Only three (8%) patients had complications, including pedicle screw penetrating pedicle into the spinal canal, pedicle screws loosing and the infection in puncture site. These results suggest that percutaneous pedicle screw internal fixation for treatment of single segment thoracolumbar fractures can correct kyphosis, improve the thoracolumbar motion, quickly relieve patient’s back pain, and the incidence of complications is low.
