- Different bones studied
- Variable time intervals between radiographs
- Differing numbers of radiographs per fracture
- In studies where fractures are immobilised with plaster, this may limit visualisation of features
- Although one study has included children whose fractures were not immobilised, these children had been abused and thus the precise time of the injury may be questionable
- Although a study has now been conducted determining the rate of healing for infant fractures this was necessarily based on clavicular fractures which may not heal at the same rate as long bones etc.
