The “Pizza Slice” orthosis: A noninvasive and low-profile dynamic traction orthosis for complex phalangeal fractures

Published:March 09, 2020DOI:


      • Traction orthoses offer conservative management of phalangeal fractures.
      • Novel design of a traction orthosis should be dynamic, low profile, and noninvasive.
      • The design enables ease in exercises such as isolated flexor digitorum profundus glides.
