Distal biceps hook test - Sensitivity in acute and chronic tears and ability to predict the need for graft reconstruction.

Background: The aim of this study was to assess the sensitivity of distal biceps hook test - O'Driscoll hook test - in a retrospective series of acute and chronic distal biceps tendon tears and investigate the ability of the test to predict the need for graft reconstruction.

Methods: We retrospectively evaluated 234 consecutive distal biceps tendon tears operated in a single centre. The result of O'Driscoll hook test and perioperative findings of distal biceps were documented in standard fashion.
