Fifty-five patients who had fusions of the anterior cervical spine were given a psychological test capable of showing personality disorders. Performance on this test was evaluated in relation to the surgical outcome. In this series of patients, 67% (10) of those with abnormal psychological test scores had a good or excellent surgical result. Of those with normal test scores 73% (29) had a good or excellent surgical result. Similarly, evaluation of the involvement of patients in compensation or litigation or both showed 69% (34) good or excellent results in those not involved in compensation or litigation, as compared with 63% (10) for those who were involved. In this investigation, neither psychological nor social considerations were found to be associated with a significantly poorer surgical result in fusions of the anterior cervical spine.
