ABSTRACT

INTRODUCTION AND IMPORTANCE: Odontoid fracture (OF) is among the most common and challenging cervical spine fractures in regards to the treatment and surgical approach. Atlanto-axial dislocation (AAD) is considered a significant complication after failed non-surgical treatment of OF. Traditionally, it requires anterior odontoidectomy followed by posterior C1-C2 reduction and fusion. In latest studies, Atlanto-axial joint (AAJ) remodeling in a posterior-only approach has got attention. CASE PRESENTATION: We herein present a 30-year-old man with missed type-II OF, presenting with irreducible anterior AAD and progressive neurological deficit. Old non-united OF with dorsal callous formation, compressing spinal cord, was detected. The patient underwent correction of the deformity and reduction of the fracture utilizing the posterior-only approach. AAJ remodeling, callous release and C1-C2 fusion was performed in standard prone position, under fluoroscopic guide and intraoperative electrophysiological monitoring. The patient had uneventful surgery and postoperative course and was neurologically intact with appropriate alignment in 6-month follow-up. CLINICAL DISCUSSION: The irreducible AAD following type-II OF could be successfully treated with posterior-only approach (C1-C2 fusion). CONCLUSION: Type-II OF is considered unstable requiring surgical management. Close follow-up and appropriate patient education is mandatory in non-surgical treatment. Irreducible AAD has been managed with anterior odontoid resection and posterior fusion. Several complications of anterior surgery, makes posterior-only approach a noticeable choice.

ABSTRACT

BACKGROUND: Different treatments are available for aggressive vertebral hemangioma [AVH], but a consensus is yet to be reached about the best therapeutic approach. PURPOSE: To explore the possibility that selecting a less aggressive therapeutic approach for AVH decreases the intraoperative and postoperative complications while providing similar clinical, radiographic, and disease-free survival results to more aggressive therapeutic methods. STUDY: We report the case of an AVH of the thoracic spine at the T5 level, treated via perioperative selective arterial embolization plus surgical decompression via laminectomy and reconstruction with polymethylmethacrylate (PMMA) vertebroplasty. PATIENT: The patient was a 17-year-old male referred to our center with the chief complaint of low back pain from two months earlier, without any response to analgesics, and with neurologic manifestations as paraparesis (one month) and progressive sphincter problems (one week). Upon imaging, the impression was an aggressive spinal tumor with cord compression. OUTCOME MEASURES: After the operation, the patient's pain immediately improved, and his neurologic manifestations progressively improved. RESULTS: The patient started walking with help about three weeks after the operation. Roughly six months later, he achieved a complete neurological recovery. At present, about two years following the operation, he has a normal life without any neurological problems. CONCLUSION: Based on our experience with AVH, the selection of less aggressive therapeutic approaches such as perioperative diagnostic angiography and selective embolization decrease the intraoperative and postoperative complications like intraoperative bleeding and neurological injury, while achieving similar clinical, radiographic, and disease-free survival outcomes to more aggressive therapeutic methods.

ABSTRACT

Giant cell tumor (GCT) is an intermediate malignant bone tumor which mostly involves long extremity bones, less commonly involving the spine with sacral predominance. Cervical spine involvement is rare. According to literature, the selective approach for the treatment of GCT is en bloc resection with spinal reconstruction. For unusual sites, such as cervical region, which is a mobile spinal segment and critically proximate to the cervical spinal cord, great vessels, and vital organs, it is almost impossible to perform the selective approach for treatment. Alternative approaches in such situations are under investigations. We present a case of C2 vertebral body GCT, who was treated with polymethylmethacrylate intravertebral injection and was followed by adjuvant therapy with denosumab. A 16-year-old boy without any past medical history presented with progressive suboccipital and axial neck pain since 3 months earlier, which had not responded to conservative treatments. There was no neurologic deficit, and pain was significantly controlled. In the 1-year follow-up, no complication and tumor recurrence was seen. Vertebroplasty with bone cement for lytic spinal GCT lesions, followed by adjuvant therapy with denosumab, not only is a less invasive treatment but also has good results in spinal stability, patient recovery, and 12-month recurrence.
