Closed avulsion of the Flexor Digitorum Profundus (FDP) from distal phalanx most commonly affects the ring finger when an extensive force is applied to a finger in active flexion. Whilst it is undoubtably reasonable to provide treatment for those who present with symptoms, there may be a cohort of people who sustain an avulsion without noticing. This study aims to quantify the effect of ring finger FDP avulsion on overall grip strength to determine the functional effect of a missed injury Right handed volunteers, with no abnormality on examination were included (N= 42). Proximal muscle group action was excluded. Grip strength was tested using a Jamar dynamometer with and without splinting of the ring finger to block flexion at the DIPJ and repeated six times alternately to mitigate the effects of fatigueIntroduction
