Post-Traumatic Longitudinal Atlanto-Occipital Dissociation without Neurodeficits Treated with Visor (Head-Neck-Chest ) Orthosis - a Rare Case Report and Review of the Literature.

Introduction: Death is the most common outcome of longitudinal atlanto-occipital dissociation (L-AOD). Even though rare, survival is commonly seen in the pediatric population. This study reports a successful outcome of a pediatric patient with an L-AOD without neurodeficits, immobilized in a visor (head-neck-chest) orthosis.

Surgical Management and Denosumab for Aneurysmal Bone Cysts of the Spine in an Australian Tertiary Paediatric Centre.

Aneurysmal bone cysts (ABC) are rare osteolytic, benign but often locally aggressive tumours of the long bones or vertebrae. For spinal ABC, surgical management, embolisation or sclerotherapy alone often carry high morbidity and/or high recurrence rates. Interruption of receptor activator of nuclear factor-kappa B ligand (RANKL) signalling holds promise as an effective therapeutic strategy for these tumours.
