The understanding of the optimal surgical timing for stabilization in thoracolumbar fractures is severely limited. Thoracolumbar spine fractures can be devastating injuries and are often associated with significant morbidity and mortality. The role of early surgical stabilization (within 48-72 hours of injury) as a vehicle to improve outcomes in these patients has generated significant interest. Goals of early stabilization include improved neurological recovery, faster pulmonary recovery, improved pain control, and decreased health care costs. Opponents cite the potential for increased bleeding, hypotension, and the risk of further cord injury as a few factors that weigh against early stabilization. The concept of spinal cord injury and its relationship to surgical timing remains in question. However, when neurological outcomes are eliminated from the equation, certain measures have shown positive influences from prompt surgical fixation. Early fixation of thoracolumbar spine fractures can significantly decrease the duration of hospital stay and the number of days in the intensive care unit. Additionally, prompt stabilization can reduce rates of pulmonary complications. This includes decreased rates of pneumonia and fewer days on ventilator support. Cost analysis revealed as much as $80,000 in savings per patient with early stabilization. All of these benefits come without an increase in morbidity or evidence of increased mortality. In addition, there is no evidence that early stabilization has any ill effect on the injured or uninjured spinal cord. Based on the existing data, early fixation of thoracolumbar fractures has been linked with positive outcomes without clear evidence of negative impacts on the patient's neurological status, associated morbidities, or mortality. These procedures can be viewed as "damage control" and may consist of simple posterior instrumentation or open reductions with internal fixation as indicated. Based on the current literature it is advisable to proceed with early surgical stabilization of thoracolumbar fractures in a well-resuscitated patient, unless extenuating medical conditions would prevent it.
目前对于胸腰椎骨折稳定化的最佳手术时机的认识极为有限。胸腰椎骨折可能是极具破坏性的损伤,常常伴有显著的发病率和死亡率。早期手术稳定化(在受伤后48 - 72小时内)作为改善这些患者预后的手段引发了广泛关注。早期稳定化的目标包括改善神经功能恢复、加快肺部恢复、更好地控制疼痛以及降低医疗成本。反对者列举了出血增加、低血压以及进一步脊髓损伤风险等因素,认为这些因素不利于早期稳定化。脊髓损伤的概念及其与手术时机的关系仍存在疑问。然而,当不考虑神经功能结果时,某些措施已显示出早期手术固定具有积极影响。胸腰椎骨折的早期固定可显著缩短住院时间和重症监护病房的住院天数。此外,及时稳定化可降低肺部并发症的发生率,包括降低肺炎发生率和减少呼吸机支持天数。成本分析显示,早期稳定化每位患者可节省多达8万美元。所有这些益处均未伴随着发病率的增加或死亡率上升的证据。此外,没有证据表明早期稳定化对受伤或未受伤的脊髓有任何不良影响。基于现有数据,胸腰椎骨折的早期固定与积极的预后相关,且没有明确证据表明对患者的神经功能状态、相关发病率或死亡率有负面影响。这些手术可视为“损害控制”,可能包括简单的后路器械固定或根据情况进行切开复位内固定。根据当前文献,对于病情已得到充分复苏的患者,建议对胸腰椎骨折进行早期手术稳定化,除非有特殊的医疗状况使其无法进行。
