ABSTRACT

Background: Type II C2 odontoid fractures are common traumatic cervical spine lesions and have the highest risk of non-union without fusion. Pseudoarthrosis may lead to extreme anatomic deformation, and poor clinical outcomes. A 50-year-old male, following a traumatic C2 dens fracture treated when the patient was 44 years of age, newly presented at age 50 with pseudoarthrosis and severe C1-C2 subluxation that required a secondary fusion using a three-dimensional (3D) printed model for appropriate surgical planning. Case Description: A 44-year-old male underwent a C1 posterior arch osteotomy to treat cervical myelopathy after a type 2 odontoid fracture. Now at age 50, he newly presented with recurrent myelopathy, and marked cord compression due to a C2 odontoid-dens pseudoarthrosis, and extreme C1 subluxation over C2. A 3D model of the patients' cervical-spine anatomy was created for surgical planning and led to an anterior C1-C2 freeing of the pseudoarthrosis, followed by a posterior C0-C1 decompression, deformity reduction, C0, C2 laminar, and C3/4 trans-articular arthrodesis. Six months postoperatively, the patient improved from a pre-operative mJOA score of 5 to a postoperative mJOA score of 14. Conclusion: A 3D model was successfully utilized to plan a secondary 360° fusion for a pseudoarthrosis diagnosed 6 years after an original C-C2type II odontoid fusion in a now 50-year-old male.

ABSTRACT

BACKGROUND: Spondylodiscitis is a severe condition where standalone antibiotic therapy resolves most cases. In refractory infections, open surgery may aid with infection debulking. However, significant morbidity can occur. Nowadays, endoscopic approaches are emerging as an alternative. However, until now, only small-scale studies exist. Being so, we carried the first systematic review on spondylodiscitis endoscopic debridement indications, technique details, and outcomes. METHODS: Search for all English written original studies approaching the spondylodiscitis endoscopic treatment was performed using PubMed and EBSCO host. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and a pre-specified protocol was registered at PROSPERO (CRD42020183657). RESULTS: Fourteen studies involving 342 participants were included for analysis. Data overall quality was fair. Indications for the endoscopic approach were poorly defined. The most consensual indication was refractory infection to conservative treatment. Spinal instability or neurological deficits were common exclusion criteria. All authors described similar techniques, and despite the frequent severe co-morbidities, procedure morbidity was low. Re-interventions were common. Microorganism identification varied from 54.2 to 90.4%. Treatment failure among studies ranged from 0 to 33%. Pain, functional status, and neurological deficits had satisfactory improvement after procedures. CONCLUSIONS: The endoscopic debridement of spondylodiscitis seems to be an effective and safe approach for refractory spondylodiscitis. A novel approach with initial endoscopic infection debulking and antibiotic therapy could improve the success of spondylodiscitis treatment.

ABSTRACT

BACKGROUND: Intracranial chondromas account for 0.2-0.3% of all intracranial neoplastic lesions and less than a quarter arise in the convexity or falx. Despite its benign nature, exceedingly rare malignant transformations exist. The misdiagnosis with meningiomas is frequent and may be related with chondromas' similar insidious clinical presentation and imaging features. Standalone surgery is advised and complete resection provides the definitive treatment. CASE DESCRIPTION: A 44-year-old female presents with insidious headache, visual disturbances, and papilledema. The imaging studies were compatible with frontal parasagittal meningioma. Surgery revealed a meningeal based mass, mostly avascular and with a well-demarked surgical plane from the brain parenchyma. Complete resection with meningeal margins was achieved and the histopathologic examination revealed a chondroma. The patient symptoms subsided and no surgical complications existed. CONCLUSION: Intracranial convexity chondromas constitute a rare differential diagnosis for meningiomas. The present case reinforces the current scarce data and serves as reminder for clinicians diagnosing and treating intracranial tumors.
