Abstract Background: Vertebral cavity sometimes occurs after posterior short-segmental fixation for thoracolumbar burst fractures, but the risk factor of its formation is unclear. We aim to investigate their vertebral healing pattern and explore the risk factor of vertebral cavities.Methods: The thoracolumbar burst fractured patient treated with posterior short segmental fixation were followed up for minimal 3 years. Healing patterns were observed and divided into 4 healing types according to the integrity status of the endplates and the morphology of the cavities. The demographic characteristics and clinical outcomes were compared between patients with and without vertebra cavities at the last follow-up.Results: The incidence of vertebral cavities in our cohort was 59.6%. Accordingly, the healing pattern of the vertebra were classified as Complete Healing type or Endplate Cavity type, Spherical Cavity type or Burst Cavity type. The proportion of men, history of smoking, severity of neurological impairment and presence of A4 type fracture were significantly higher in the Vertebral Cavity group than the Intact Vertebra group. Clinical outcomes, including ASIA scales,VAS and ODI scores, were similar between the Intact Vertebra group and the Vertebral Cavity group. Conclusions: Vertebral cavities are commonly seen after posterior short-segmental fixation for thoracolumbar burst fractures. The healing pattern can be divided into four types. The presence of vertebral cavity may be related to gender, smoking history and the severity of the fracture. Most of the vertebral cavities are asymptomatic, but the clinical significance needs further study.

Object. Experimental burst fracture models are often developed by using either single or incremental impacts. In both protocols, the weight-drop technique produces the impact. However, to the authors' knowledge in no study have researchers attempted to compare the equivalence of the spine burst fracture produced using the different impact protocols. This study was performed to investigate whether the single and incremental trauma approaches produce equivalent degrees of severity in thoracolumbar burst fractures. Methods. Twenty bovine thoracolumbar spines comprising three vertebrae were divided evenly into the single impact and incremental impact groups. The specimens in the incremental impact group were subjected to three axial compressive impacts of increasing energy (78.4, 107.8, and 137.2 J), whereas specimens in the other group were subjected to a single impact (137.2 J). Before and after the final trauma, multidirectional flexibility of each specimen was measured under flexion/extension, right/left lateral bending, and right/left axial rotation, thus quantifying the instability of the fracture. The flexibility parameters were then compared between the two groups. Results. A significant increase in flexibility parameters was found after the final trauma in both groups, indicating the instability of the spine (p < 0.01). No significant differences in flexibility parameters were observed in either intact status or injured status between the two groups (p > 0.05). Conclusions. In this study the authors have confirmed that the single and incremental impact protocols produced a similar degree of severity in producing an in vitro bovine burst fracture. The results of this study support the use of the incremental impact protocol in future experimental biomechanical studies.

ABSTRACT The number of fixed segments in the surgical treatment of thoracolumbar burst fractures remains controversial. This study aims to compare the results of short and long fixation in thoracolumbar burst fractures through a meta-analysis of studies published recently. MEDLINE and Cochrane databases were used. Randomized controlled trials and non-randomized comparative studies (prospective and retrospective) were selected. Data were analyzed with the software Review Manager. There was no statistically significant difference in the Cobb angle of preoperative kyphosis. Long fixation showed lower average measurements postoperatively (MD = 1.41; CI = 0.73-2.08; p<0.0001) and in the last follow-up (MD = 3.98; CI = 3.22-4.75; p<0.00001). The short fixation showed the highest failure rates (RD = 4.03; CI = 1.33-12.16; p=0.01) and increased loss of height of the vertebral body (MD = 1.24; CI = 0.49-1.98; p=0.001), with shorter operative time (MD = -24.54; CI = -30.16 - -18.91; p<0.00001). There was no significant difference in blood loss and clinical outcomes. The high rates of kyphosis correction loss with short fixation and the lower correction rate in the immediate postoperative period were validated. There was no significant difference in the blood loss rates because arthrodesis was performed in a short segment in the analyzed studies. The short fixation was performed in a shorter operative time, as expected. No study has shown superior clinical outcomes. The short fixation had worse rates of kyphosis correction in the immediate postoperative period, and increased loss of correction in long-term follow-up, making the long fixation an effective option in the management of this type of fracture.

Purpose. To determine the role of history of prostatitis (HP) as an independent risk factor for erectile dysfunction (ED) in Chinese adult males. Methods. We conducted an online survey using a crowd-sourced questionnaire in Chinese adult males. The participants were separated into two groups as adult participants with HP and with no history of prostatitis (NHP) according to the medical history record. As diagnosis criteria of ED, we used the 5 questions of the International Index for Erectile Function (IIEF-5). The general data including height, weight, monthly income, academic background, smoking history, alcohol drinking, marital status, conjugal affection, and other disease history was asked and recorded. The relationship between HP and ED using the chi-square test and logistic regression analyses was investigated and analyzed. Results. In total, 1873 participants answered the questionnaire. 95 participants in the HP group and 1778 participants in the NHP group were included in this study. The rate of participants with HP was 5.343%. ED was found in 68.4% of the HP group and 43% of the NHP group ( p < 0.001 ). Regression analysis showed that participants in HP were more likely to have ED (OR 2.135, 95% CI 1.266–3.60) after adjusting for the participant’s age, body mass index (BMI), monthly income, academic background, smoking history, alcohol drinking, marital status, conjugal affection, BPH, hypertension, and diabetes mellitus, when compared with NHP. Conclusions. The present study indicated a high prevalence of ED in Chinese adult males with history of prostatitis, and HP is an independent risk factor for erectile dysfunction.

Unstable thoracolumbar burst fractures are serious injuries and their management remains controversial. Some authors advocate the use of short-segment posterior instrumentation (SSPI) for certain burst fractures which offers several benefits including preservation of motion segments; however, clinical studies have shown mixed results. Whether crosslinks contribute sufficient stability to this construct has not been determined, therefore the objective of this study was to evaluate the biomechanical characteristics of short-segment posterior instrumentation, with and without crosslinks, in an unstable human burst fracture model.

Object Despite extensive published research on thoracolumbar burst fractures, controversy still surrounds which is the most appropriate treatment. The objective of this study was to evaluate the scientific literature on operative and nonoperative treatment of patients with thoracolumbar burst fractures and no neurological deficit. Methods In their search of the literature, the authors identified all possible relevant studies concerning thoracolumbar burst fracture without neurological deficit. Two independent observers performed study selection, methodological quality assessment, and data extraction in a blinded and objective manner for all papers identified during the search. In a synthesis of the literature, the authors obtained evidence for both operative and nonoperative treatments. Conclusions There is a lack of evidence demonstrating the superiority of one approach over the other as measured using generic and disease-specific health-related quality of life scales. There is no scientific evidence linking posttraumatic kyphosis to clinical outcomes. The authors found that there is a strong need for improved clinical research methodology to be applied to this patient population.

Abstract Background: For fresh thoracolumbar burst fracture, a new method which can not only promote the fracture healing, but also retain the movement segment, and restore the spinal movement function to the maximum extent is needed. The purpose of this study is to determine the performance of stabilization of a semi-rigid stabilization system combined with transpedicular intracorporeal bone grafting for thoracolumbar burst fractures.Methods Six thoracolumbar cadaver spines were used for testing. A controlled L2 burst fracture was created. The L1-3 motions were determined.Results In extension, flexion and lateral bending, the semi-rigid fixator stabilized the segment to a range of motion(ROM) and neutral zone(NZ) below the magnitude of the intact spine, but showed increased ROM and NZ of axial rotation (P < 0.05) compared with the intact spine.Conclusions Restoration of stability with the semi-rigid dynamic system combined with transpedicular intracorporeal bone grafting is possible in flexion, extension, right and left lateral bending for thoracolumbar burst fracture but for axial rotation.
