Speculation about the partial absence of the FDB tendon attributes it to degenerative changes among diverse populations or evolutionary adaptations [, Other studies focused on variation in the foot musculature reveal that the absence of the FDB tendon is associated with the presence of a particularly rare muscle called the flexor digiti quinti (FDQ), whose tendon extends from the common flexor digitorum longus [, Together, these findings suggest that, although compensatory variations are frequently associated with a missing flexor digitorum brevis tendon, there may ultimately be little functional effect on individuals with an absent tendon. ; Zipfel, B.; DeSilva, J.M.
