Factors influencing the outcome of bone grafting surgery for scaphoid fracture non-union.

The results of a consecutive series of bone-grafting procedures for non-union of scaphoid fractures were assessed in order to investigate whether the patient's age or the delay between acute fracture and bone-graft surgery influenced the outcome. One hundred and thirty-four patients with a mean follow up of 2.6 years from bone-graft surgery for scaphoid fracture non-union were assessed for post-operative pain and radiographic evidence of union. No association was found between the union rate following surgery and either the patients' ages or the interval between the original injury and subsequent non-union surgery.
