Polydactyly of the hand.

Contents

Choice of modality

X-ray is generally the initial choice.

Evaluation

  • Number of supernumerary digits.[1]
  • Development as compared to "normal" digits
  • Duplication can be stated at least when it is difficult to structurally distinguish any supernumerary digit from the "normal" digit that shares the same proximal attachment site.
  • Structure of the attachment site, for example forming a joint with a certain metacarpal/metatarsal or phalangeal bone
  • Whether that proximal bone is normal or for example broadened at the attachment.
  • Fusion of even the distal parts of a supernumerary digit (syndactyly) is called polysyndactyly.[2]
  • Angulation of the most proximal part of the supernumerary digit, and can usually described as mild/moderate/severe valgus or varus and not necessarily numerically.
  • Any other abnormality in the projected skeleton, since the condition is associated with many syndromes.[1]
