研究目的:

随着社会的发展,中国社会老龄化的进程不断加快,随着老龄人口基数不断增加,骨质疏松性脊柱骨折 (osteoporotic vertebral compression fracture,OVCF)也越来越常见,然而老年人行动不便,对该疾病认识有限,往往在发生胸腰椎骨折后错过最佳就诊时间,从而逐渐演变为陈旧性压缩性骨折。脊柱后凸、驼背、伤椎高度下降、压迫神经,严重影响着患者的生活质量。脊柱骨折若压缩大于原高度的2/3或合并中、后柱损伤的骨折被定义为脊柱的不稳定性骨折,如果合并椎管受压,治疗十分困难。目前治疗胸腰段脊柱骨折的常见手术方案包括经皮椎弓根钉内固定术。但仅通过椎弓根钉撑开伤椎恢复高度,在OVCF患者中因其松质骨压缩而无法完全复位,导致伤椎前产生蛋壳样改变。最终将导致伤椎前柱的支撑力下降,钉棒固定在治疗后期发生松动甚至断裂。对于椎管后壁完整、不合并神经症状的骨质疏松性稳定性椎体骨折应用经皮椎体成形术(PVP)和经皮椎体后凸成形术(PKP)治疗的疗效在全球范围已得到广泛认可。而PKP手术仅通过在伤椎注入骨水泥进行固化,并非在脊柱总体上达到力学平衡。有研究指出 PVP、PKP术后3个月至1年是椎体再骨折的高发期,发生率为12.5%~15.6%。将经皮椎弓根钉内固定术的脊柱稳定性,与PKP的椎体稳定性相结合,能有效地弥补两种术式的缺点,同时放大两种术式的优势,为骨质疏松性脊柱压缩骨折提供更优解决方案。近年来,国内外有许多学者对这种联合治疗OVCF的手术方法进行探究,但缺少对照实验且伴胸腰椎不稳定的患者较少。本研究目的在对比单纯PKP与骨水泥强化经皮螺钉结合PKP治疗不稳定的骨质疏松压缩性胸腰椎骨折的疗效,探究新型联合手术治疗的效果。  

Objectives of Study:

The prevalence of osteoporotic vertebral compression fracture (OVCF) is currently on the rise, with a predominance in the elderly. Elderly people with limited mobility and poor disease awareness usually fail to seek the best medical care after a thoracolumbar fracture, which gradually evolves into a compression fracture and results in kyphosis, hunchback, loss of height of the injured vertebrae, and compression of nerves, seriously compromising the quality of life of patients. Burst fractures of OVCF with vertebral compression exceeding 2/3 of the original height or combined with injury to the middle and posterior columns are considered unstable fractures and are currently challenging for management. Internal fixation with percutaneous pedicle screws is a common surgical option for the treatment of thoracolumbar spine fractures. However, simple bracing of the vertebral body by posterior pedicle screws prevents complete repositioning of the injured vertebra due to cancellous bone compression, resulting in an eggshell-like change anteriorly. In addition, decreased support in the anterior column of the injured spine leads to screw loosening or even fractures. The efficacy of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) for osteoporotic stable vertebral fractures with an intact posterior canal and no neurological symptoms has been widely established worldwide. PKP relies on the injection of bone cement into the injured vertebra to increase the stiffness of the vertebral body, which simply highlights the curing of the injured vertebra at the expense of the overall mechanical balance of the spine. It has been noted that 3 months to 1 year after PVP and PKP is a period of high occurrence of vertebral re-fracture, with an incidence of 12.5% to 15.6%. The combination of the spinal stability of percutaneous internal pedicle nailing with the vertebral stability of PKP can effectively compensate for the shortcomings and amplify the merits of both procedures, providing a better solution for OVCF. To this end, the current research was performed to compare the efficacy of PKP versus percutaneous cement-augmented screw fixation plus PKP in the management of unstable OVCF.
