Failure of treatment of ununited fractures of the carpal scaphoid. The role of non-compliance.

We studied the results in thirty patients who had grafting of an ununited fracture of the carpal scaphoid bone. Psychiatric evaluations revealed that the thirteen patients who had a non-union of the initial scaphoid bone graft had significant psychiatric problems, whereas the seventeen patients in whom the non-union had healed after initial bone-grafting of the scaphoid did not have psychiatric abnormalities. Technically successful surgical revisions in the first group of patients did not result in significant clinical improvement. We concluded that most failures of the bone grafts were related to non-compliance on the part of the patient and that some of the operations could have been avoided if the underlying psychiatric problems had been recognized preoperatively.
