Surgical Management of Traumatic Cervicothoracic Junction Spondyloptosis Without Neurological Injury: A Case Report and Review of the Literature.

Acute traumatic cervical spondyloptosis in neurologically intact patients is uncommon and involvement of the cervicothoracic junction is rare. Herein, we report a case of traumatic C7-T1 spondyloptosis in a 56-year-old neurologically intact male patient, with radiographic findings of C7-T1 grade V traumatic listhesis associated with C7 floating segment, cord compression with myelomalacia, extensive ligamentum injury, and intervertebral disc traumatic change and protrusion. He underwent global spine fixation starting with a posterior approach.

Prevalence and classification of accessory navicular bone: a medical record review.

Background: The accessory navicular bone (ANB) is one of the most common accessory bones in the foot. Certain pathologies, such as posterior tibial tendon insufficiency are associated with ANB, and should be differentiated from midfoot and hindfoot fractures such as navicular tuberosity avulsion fractures. There are few studies addressing the prevalence and types of ANB in Saudi Arabia.
