Multi-center, prospective, non-randomized study to evaluate outcomes of surgically treated patients with adult cervical spinal deformity.
Adult cervical deformity (ACD) is an uncommon but potentially severely debilitating condition with a broad range of causes that include but are not limited to spondylosis, inflammatory arthropathy, trauma, infection, iatrogenic, neoplastic, congenital, and neuromuscular processes. In general, sagittal plane deformities typically produce kyphosis, and coronal plane deformities result in scoliosis. Cervical kyphotic deformities are most commonly encountered in the setting of prior surgical destabilization, while cervical scoliosis is most commonly associated with congenital and neuromuscular con…
Inclusion Criteria: * ≥18 years old at time of treatment * Diagnosis of cervical deformity- must meet one or more of the following criteria: * C2-C7 sagittal kyphosis (Cobb \> 15 degrees) * T1S-CL \> 35o * Segmental cervical kyphosis \> 10 degrees between any 2 vertebra between C2-T1 or \> 15 degrees across any 3 vertebra between C2-T1 * Cervical scoliosis \> 10 degrees (Cobb angle must include end vertebra within the cervical spine) * C2-C7 SVA \> 4cm * McGregor's slope \> 20 degrees or CBVA \> 25 degrees OR * Planned Revision surgery for proximal junctional failure with an an…
Surgical interventions will be patient specified by treating surgeon.
