BACKGROUND: Unstable conditions of the craniocervical junction such as atlanto-occipital dislocation (AOD) or atlanto-axial instability (AAI) are severe injuries with a high risk of tetraplegia or death. Immobilization by a cervical collar to protect the patient from secondary damage is a standard procedure in trauma patients. If the application of a cervical collar to a patient with an unstable craniocervical condition may cause segmental motion and secondary injury to the spinal cord is unknown...

PURPOSE: Retro-odontoid pseudotumor is common in elderly people and is a cause of cervical myelopathy. The goal of the study was to investigate surgical procedures, outcomes, and post-operative spontaneous regression of posterior cervical retro-odontoid pseudotumors. METHODS: The subjects were 29 patients who underwent surgery for myelopathy due to a retro-odontoid pseudotumor around the craniocervical region at 9 facilities and were followed-up for an average of 54 months (range 12-96 months)...

BACKGROUND: The involvement of the cervical spine in rheumatoid arthritis (RA) continues to be of clinical importance even in this age of biologics. Pathophysiological changes begin with an isolated atlantoaxial subluxation and may progress to a complex craniocervical and subaxial instability. The onset of cervical myelopathy can occur at any time and leads to a deterioration of the prognosis for the patient. THERAPY: Treatment of the rheumatoid cervical spine should be aimed at improvement of the symptoms and prevention of further progress of the disease...

BACKGROUND: Fusion rates following rigid internal instrumentation for occipitocervical and atlantoaxial instability approach 100% in many reports. Based on this success and the morbidity that can be associated with obtaining autograft for fusion, surgeons increasingly select alternative graft materials. OBJECTIVE: To examine fusion failure using various graft materials in a retrospective observational study. METHODS: Insurance claims databases (Truven Health MarketScan® [Truven Health Analytics, Ann Arbor, Michigan] and IMS Health Lifelink/PHARMetrics [IMS Health, Danbury, Connecticut]) were used to identify patients with CPT codes 22590 and 22595...

Pierre Robin Sequence (PRS) can be associated with skeletal dysplasias, presenting with craniocervical instability and devastating spinal injury if unrecognized. The authors present the case of an infant with PRS and a type II collagenopathy who underwent multiple airway-securing procedures requiring spinal manipulation before craniocervical instability was identified. This resulted in severe cervical cord compression due to odontoid fracture and occipitoatlantoaxial instability. This case highlights the importance of early cervical spine imaging and cautious manipulation in infants with PRS and suspected skeletal dysplasia...

Chiari malformation (CM) is the most common and prevalent symptomatic congenital craniocervical malformation. Radiological diagnosis is established when the cerebellar tonsils are located 5 mm or more below the level of the foramen magnum on magnetic resonance imaging (MRI). Surgical treatment is indicated whenever there is symptomatic tonsillar herniation or syringomyelia/hydrocephalus. The main surgical treatment for CM without craniocervical instability (such as atlantoaxial luxation) is posterior fossa decompression, with or without duraplasty...

Background: Craniocervical junction pathology is infrequent in daily neurosurgical practice. In general, most of these lesions are of traumatic or rheumatic origin. Atlantoaxial instability of inflammatory origin (Grisel syndrome) is a rare entity of which only 16 adult cases have been reported in the literature. This pathology is characterized by the development of an osteolytic lesion at the level of the atlantoaxial joint after an infectious event, usually of the upper airways. Case Description: We present the case of a 76-year-old patient who attended our office for clinical symptoms of spinal instability secondary to an osteolytic lesion, with involvement of C1 and C2...

Purpose: Researchers have sought to better understand Chiari type I malformation (CMI) through morphometric measurements beyond tonsillar position (TP). Soft tissue and bone structures within the brain and craniocervical junction have been shown to be different for CMI patients compared to healthy controls. Yet, several morphological characteristics have not been consistently associated with CMI. CMI is also associated with different prevalent conditions (PCs) such as syringomyelia, pseudotumor, Ehlers-Danlos syndrome (EDS), scoliosis, and craniocervical instability...

INTRODUCTION: Plasmacytomas, considered to be the solitary counterparts of multiple myeloma, are neoplastic monoclonal plasma cell proliferations within soft tissue or bone. Plasmacytomas often present as a collection of findings known as POEMS-syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, M-Protein spike, and Skin changes). CASE DESCRIPTION: We present a report of a 47 yo male diagnosed with POEMS-syndrome secondary to a skull base plasmacytoma. The mass resulted in marked instability of the cranio-cervical junction due to bony erosion...

BACKGROUND: Odontoid process pathologies can cause upper motor neuron lesions. These pathologies can be approached through either a high retropharyngeal approach or a transoral approach. The introduction of the surgical microscope, proper instrumentations, and proper antibiotics has increased utilization of the transoral approach. QUESTIONS/PURPOSES: Our approach to anterior odontoid resection through transoral approach for different pathologies resulting in compression the cervical cord or causing craniocervical instability is described here...

STUDY DESIGN: Case report. OBJECTIVE: To report the first case in the literature of a traumatic cervical spine subdural cerebrospinal fluid (CSF) collection (hygroma) under tension causing cord compression. We suggest etiopathogenesis and modality of treatment. SUMMARY OF BACKGROUND DATA: Hygromas are subdural cranial CSF collection. A literature review showed no previous published case of post-traumatic spinal hygroma. This was a potential life-threatening sequelae of a high cervical injury that warranted early diagnosis and emergency treatment...

There is growing recognition of the kyphotic clivo-axial angle (CXA) as an index of risk of brainstem deformity and craniocervical instability. This review of literature and prospective pilot study is the first to address the potential correlation between correction of the pathological CXA and postoperative clinical outcome. The CXA is a useful sentinel to alert the radiologist and surgeon to the possibility of brainstem deformity or instability. Ten adult subjects with ventral brainstem compression, radiographically manifest as a kyphotic CXA, underwent correction of deformity (normalization of the CXA) prior to fusion and occipito-cervical stabilization...

The Ehlers-Danlos syndromes (EDS) are a heterogeneous group of heritable connective tissue disorders characterized by joint hypermobility, skin extensibility, and tissue fragility. This communication briefly reports upon the neurological manifestations that arise including the weakness of the ligaments of the craniocervical junction and spine, early disc degeneration, and the weakness of the epineurium and perineurium surrounding peripheral nerves. Entrapment, deformation, and biophysical deformative stresses exerted upon the nervous system may alter gene expression, neuronal function and phenotypic expression...

Injuries to the craniocervical support structures are frequently observed in neurotrauma cases. Stability of this region is of vital importance. Literature has mainly focused on three major ligaments of the craniocervical junction: The tectorial membrane, the transverse ligament, and the alar ligaments. However, the accessory atlantoaxial ligament (ALL) also seems to be involved in craniocervical stability as shown in cadaveric specimens. Still, the biomechanical importance of this structure needs to be determined, especially in trauma settings...

Here we report a single-stage operation we performed on a patient with a large schwannoma that extended from the lower clivus to the cervico-thoracic junction caudally. A number of authors have previously performed multilevel laminectomy to remove giant schwannomas that extend for considerable length. This technique has caused cervical instability such as kyphosis or gooseneck deformity on several occasions. We removed the tumor with a left lateral suboccipital craniectomy with laminectomy only at C1 and without any subsequent surgery-related neurologic deficits...

Severe os odontoideum causing ventral brainstem compression is a rare and difficult entity to treat. It is generally accepted that severe os odontoideum causing ventral brainstem compression and neurological deficits warrants surgical treatment. This often requires both anterior and posterior procedures. Anterior approaches to the craniocervical junction are fraught with complications, including infection and risk of injury to neurovascular structures. External traction systems traditionally require long-term bedrest...
