Cervical teardrop fractures are hyperflexion and axial loading injuries associated with significant ligamentous disruption. Patients sustaining these types of injury are classically treated with a cervical corpectomy and anterior fusion. However, there are notable disadvantages of this approach, namely, disruption of the patient's true anatomic alignment and a reduction in the number of fixation points available for cervical fusion. Here we present a novel method of open reduction and internal fixation in a neurologically intact patient with cervical teardrop fracture.
A 34-year-old man presented to Ryder Trauma Center after a helmeted motorcycle accident. The patient was found to be neurologically intact on arrival, and imaging demonstrated a C5 teardrop fracture without bony retropulsion. The patient was taken to the operating room for an open reduction and internal fixation of the fracture using a novel technique. This technique used traditional diskectomies at the C4-5 and C5-6 levels, along with a temporary, unicortical screw into the C5 body to capture the anteriorly displaced fragment. A bicortical screw was then placed into the contralateral side, and now, having fully reduced the fracture, the first (temporary) screw was replaced with a bicortical screw. The patient was neurologically intact postoperatively, with 2-month follow-up computed tomography scan demonstrating stable reduction of the fracture.
Here we present a novel technique for open reduction and internal fixation of a cervical teardrop fracture that does not require cervical corpectomy. This technique is particularly useful in patients with an anteriorly displaced fragment and without neurologic deficit or compromise.
颈椎泪滴样骨折是过伸和轴向加载损伤,与明显的韧带撕裂有关。经典的治疗方法是颈椎椎体切除术和前路融合术。然而,这种方法存在明显的缺点,即破坏了患者的真实解剖对位,减少了颈椎融合术的固定点数量。在这里,我们介绍了一种新的方法,用于治疗颈椎泪滴样骨折的神经完整患者。
一名 34 岁的男子在戴头盔的摩托车事故后被送往莱德创伤中心。患者入院时神经功能完整,影像学检查显示 C5 泪滴样骨折,无骨块后突。患者被送往手术室,采用一种新的技术进行骨折的切开复位内固定。该技术在 C4-5 和 C5-6 水平使用传统的椎间盘切除术,并在 C5 体上临时使用单皮质螺钉固定向前移位的骨折块。然后在对侧放置双皮质螺钉,现在骨折已完全复位,第一个(临时)螺钉被双皮质螺钉取代。患者术后神经功能完整,2 个月的随访 CT 扫描显示骨折稳定复位。
我们在这里介绍了一种治疗颈椎泪滴样骨折的新方法,无需颈椎椎体切除术。该技术特别适用于有前移位骨折块且无神经功能障碍或损害的患者。
