Abstract: Objective To explore the diagnostic value of SPECT/CT on fracture healing.Methods A total of 28 patients (13 males,15 females; average age 45.3 years) with fracture were enrolled.All underwent metal fixation.SPECT/CT scans were performed at least 6 months after the metal fixation.X-ray examination before SPECT/CT showed equivocal fracture healing.The fracture delayed union or nonunion were judged by degree of uptake as well as uptake pattern around fracture site.Final diagnosis was confirmed by surgery or follow-up X-ray film.Results Among 28 patients,15 showed delayed union (confirmed by follow-up),and 13 showed nonunion (confirmed by surgery).There were 13 screws in 6 patients showed abnormal uptake,suggesting screw loose (confirmed by surgery).Conclusions SPECT/CT imaging could be of clinical significance in assessing fracture healing.
