Abstract

Background: The goal of surgery for spinal injuries is fracture reduction, fixation and stable healing in a physiological position. Several open and minimally invasive surgical techniques are available.

Objective: The extent of open reduction and the fixation potential achieved by the AOSpine (AT) and Kluger (KT) techniques were compared. The influence of fracture morphology, age, sex, and bone quality on fracture reduction and secure fixation was investigated.

Material and methods: In this monocentric retrospective cohort study data of patients with traumatic thoracolumbar and lumbar fractures treated by AT or KT were analyzed. The bisegmental kyphotic angle (bGDW) of each injured spinal segment was determined. Normal bGDW values were extrapolated from the literature. The change of bGDW over time was analyzed under consideration of the bone quality in Hounsfield units (HU), injury severity according to the AOSpine classification, gender and age of patients.

Results: A total of 151 data sets were evaluated. The AT and KT methods achieved a similar extent of reduction (AT 10 ± 6°, KT 11 ± 8°; p = 0.786). In follow-up a mean reduction loss of -5 ± 4° was seen. The technique had no influence on this (p = 0.998). The fracture morphology just managed to achieve a significant influence (p = 0.043). Low HU correlated significantly but weakly with lower extent of reduction (r = 0.241, p < 0.003) and greater reduction loss (r = 0.272, p < 0.001). In the age group 50-65 years 21% of men and 43% of women had bone quality of < 110 HU. Age and HU were significantly correlated (r = -0.701, p < 0.001).

Conclusion: The AT and KT are equivalent in terms of reduction and secure fixation properties. The high proportion of male and female patients with HU < 110 in the age group under 65 years and the influence on reduction and secure fixation emphasize the need for preoperative bone densitometry.

[胸腰椎骨折手术治疗后局部脊柱轮廓:复位技术和骨质量的影响]。

背景:脊柱损伤手术的目标是骨折复位、固定和在生理体位稳定愈合。几种开放和微创手术技术是可用的。目的:比较AOSpine (AT)和Kluger (KT)技术的切开复位程度和固定电位。研究骨折形态、年龄、性别和骨质量对骨折复位和安全固定的影响。材料和方法:在本单中心回顾性队列研究中，对经AT或KT治疗的创伤性胸腰椎骨折患者的资料进行分析。测定各损伤脊柱节段的后凸角(bGDW)。正常的bGDW值由文献推断。考虑Hounsfield单元骨质量(HU)、AOSpine分类损伤严重程度、患者性别和年龄，分析bGDW随时间的变化。结果:共评估了151组数据集。AT和KT方法实现了相似程度的还原(AT 10 ±6°，KT 11 ±8°; p = 0.786)。在随访中，平均复位损失为-5 ±4°。技术对其无影响(p = 0.998)。骨折形态刚好达到显著影响(p = 0.043)。低HU与复位程度显著相关，但与复位程度弱相关(r = 0.241,p )。结论:AT与KT在复位和安全固定性能上相当。HU患者男女比例高

期刊介绍： Der Unfallchirurg is an internationally recognised publication organ. The journal deals with all aspects of accident surgery and reconstruction surgery and serves the continuing medical education of surgeons and accident surgeons with own practices and those working in hospitals. Practically-oriented works provide an overview on selected topics and offer the reader a summary of current findings from all fields of accident surgery. Besides the imparting of relevant background knowledge, the focus is on the assessment of scientific findings under consideration of practical experience. The reader is given concrete recommendations for his/her practical work.
