Infections associated with spinal implants.

Spinal infections represent a difficult challenge to treating clinicians. Infections in the presence of implants are even more so. In this review the literature appears to reflect a change of practice in which the aim is to retain implants if possible. The newer spinal procedures such as disc replacements pose different problems largely due to the more difficult access. The situation in the spine is more difficult than in general orthopaedics when dealing with infection due to the requirement for stability and to protect neurological function. The main thrust of management, therefore, is early diagnosis and a high index of suspicion followed by adequate if not radical management in a multidisciplinary setting. In the event prevention is better than cure and therefore consideration of the various mechanisms to avoid infection must be taken. There are some 'novel' considerations for the avoidance of infection alongside the tried and tested techniques. There are also new procedures for wound closure and the elimination of dead space.
