Cervical alignment after single-level anterior cervical corpectomy and fusion using autologous bone graft without spinal instrumentation for cervical pyogenic spondylitis

REVISION RECONSTRUCTION OF THE CERVICAL SPINE IN A PATIENT WITH EARLY DEEP SSI COMPLICATED BY ANGULAR KYPHOSIS: clinical case and literature review

Background. Deep surgical site infection (DSSI) is one of the most severe complications in spinal surgery. The timing and nature of DSSI are the determining criteria in the choice of treatment tactics. Aim. To present a unique clinical case of early deep SSI after ACDF in a patient with multisegmental degenerative spinal canal stenosis, complicated by epidural abscess and angular kyphotic deformity. Angular kyphosis correction, corpectomy of C4-6 and three-column cervical reconstruction were performed in one surgical session. Case presentation. A 57-year-old patient was admitted to the clinic after staged surgical interventions on the cervical spine for multilevel degenerative stenosis of the spinal canal. The primary surgical interventions were complicated by DSSI in the early period after the second surgery with formation of angular kyphosis of the cervical spine. The patient underwent revision one-stage reconstructive intervention to correct the deformity, decompress the spinal canal, and three-column reconstruction of C3-7 segments. Long-term follow-up showed persistent reduction of pain syndrome, improved quality of life and absence of recurrence of DSSI. Conclusion. The presented case illustrates the possibilities of one-stage revision three-column cervical spine reconstruction for correction of sagittal profile, decompression of intracanal neural structures and ensuring stability of operated segments. Use of DSSI treatment algorithms based on Prinz V. and Vajkoczy P. classification contributes to the selection of the optimal tactics of patient management.

Three-Staged Surgical Strategy as a Combined Approach for Multilevel Cervical Pyogenic Spondylodiscitis

Cervical pyogenic spondylodiscitis is rare but can lead to severe clinical problems that often require aggressive surgical treatment for neurological deterioration and life-threatening conditions. Although combined surgical procedures are often utilized to treat multilevel cervical regions, there is a clinical debate regarding the appropriate order and timing of surgeries using the anterior and posterior approaches. Here, we report a case of severe multilevel cervical pyogenic spondylodiscitis treated using a three-staged surgical strategy consisting of cervical laminectomy, posterior fixation, and anterior corpectomy and fusion with an autologous long bone graft; the outcome was quite favorable. Our report demonstrates the safety and usefulness of three-staged surgery in the multilevel cervical region, especially under urgent situations.

Reduction and Open Fixation of a Cervical Teardrop Fracture: A Technical Note

BACKGROUND

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.

CASE DESCRIPTION

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.

CONCLUSIONS

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.
