In a time of limited resources, the debate continues
over which types of hip prosthesis are clinically superior and more
cost-effective. Orthopaedic surgeons increasingly need robust economic
evidence to understand the full value of the operation, and to aid
decision making on the ‘package’ of procedures that are available
and to justify their practice beyond traditional clinical preference. In this paper we explore the current economic debate about the
merits of cemented and cementless total hip replacement, an issue
that continues to divide the orthopaedic community. Cite this article:
Traumatic atlanto-axial subluxation is a rare injury which may not be revealed on routine radiographs, especially when there is muscle spasm. We report on seven patients with atlanto-axial subluxation as a result of neck injury; only two of them had significant head injuries. Three patients presented with a neurological deficit attributable to the injury, one immediate and two with delayed onset. Traumatic atlanto-axial instability, occurring in an otherwise healthy patient, has a potential for neurological disaster; early consideration of operative treatment is indicated.
