متن کاملNon-operative management of occipital condyle frature: report of three cases and literature review
Occipital condyle fractures (OCF) had been difficult to diagnose, but the widespread use of computed tomography (CT) as a diagnostic tool in patients with significant cranio-cervical injury has led to increased recognition of this injury. The incidence of OCF in severely injured blunt trauma patients is estimated at 0.1 4.4% and as high as 16% overall when less severely injured patients are inc...
