A 35-year-old female patient sustained three contiguous vertebral fractures at the thoracolumbar junction while jumping off the third floor in a suicide attempt. Initial fracture treatment occurred in the setting of a multiple injury scenario. While the Th12 and the L1 vertebral fractures were considered stable, the L2 fracture exhibited a complete burst configuration with 80% canal compromise due to a posterior wall fragment causing paraplegia. A posterior pedicle screw stabilisation with indirect fracture reduction was carried out initially from T12 to L3. At 1 year follow-up the patient presented to us for new onset radiculopathy L2, and loss of correction. A circumferential revision surgery with an expandable cage was carried out to restore the anterior and posterior columns. Unfortunately again loss of reduction with kyphosis occurred, this time at the upper instrumented vertebra, which made another revision necessary. In this situation a longer construct was chosen using a combined approach and a Mesh cage. This later procedure was complicated by a postoperative paraparesis believed to be vascular in origin. Six months later a further complication involving MSSA deep wound infection required a series of irrigation debridement for healing. At the 2.5 years follow up the spine was stable and the patient had a neurologic recovery allowing her to ambulate with crutches. This Grand Round Case raises the question on the initial management of multiply injured patients with spine fracture, the classification of these fractures, the optimal initial internal fixation, the need for complementary anterior column reconstruction and the strategy when all these fails.
一名35岁女性患者在跳楼自杀未遂时,胸腰段交界处连续发生三处椎体骨折。最初的骨折治疗是在多发伤的情况下进行的。虽然T12和L1椎体骨折被认为是稳定的,但L2骨折呈现出完全爆裂型,由于后壁骨折块导致椎管狭窄80%,并引起截瘫。最初从T12至L3进行了后路椎弓根螺钉固定并间接复位骨折。在1年随访时,患者因新发L2神经根病和矫正丢失前来就诊。进行了一期前路可扩张椎间融合器的翻修手术以恢复前柱和后柱。不幸的是,再次出现了复位丢失和后凸畸形,这次发生在上端固定节段,这使得再次翻修成为必要。在这种情况下,采用联合入路和Mesh椎间融合器选择了更长的内固定节段。后来的手术出现了术后轻截瘫的并发症,据信其起源于血管。6个月后,又出现了涉及耐甲氧西林金黄色葡萄球菌深部伤口感染的并发症,需要进行一系列冲洗清创术以促进愈合。在2.5年随访时,脊柱稳定,患者神经功能恢复,能够借助拐杖行走。这个病例讨论提出了关于多发伤合并脊柱骨折患者的初始治疗、这些骨折的分类、最佳初始内固定、补充性前柱重建的必要性以及当所有这些措施均失败时的策略等问题。
