  1. Imaging of clinically suspected scaphoid fractures with normal radiographs: comparison of MRI, CT and Bone Scintigraphy. CT and MRI were compared in a prospective study. Additionally, a Cochrane Diagnostic Test Accuracy Review was performed. The prospective trial and review showed comparable results for all modalities. We advise to perform MRI or CT as soon as possible.
  2. Clinical evaluation of (suspected) scaphoid fractures in wrist trauma. First a systematic review and meta-analysis was conducted. Based on these data, a clinical prediction rule was developed and validated in a large prospective cohort (the Amsterdam Wrist/Scaphoid Rules). The rule can be used in the Emergency Department and results in less unnecessary cast immobilization, reduces the use of imaging without increasing the risk of a missed fracture.
