Quadrigia vs. Lumbrical Plus finger
Quadregia effect = overtightening/scarring of FDP tendon; decreased finger flexion in adjacent fingers s/p FDP repair ***weak grasp Pathoanatomy FDP tendons of long, ring, and little fingers share a common muscle belly therefore excursion of the combined tendons is equal to the shortest tendon; improper shortening of a tendon during repair results in inability to fully flex adjacent fingers Lumbrical Plus finger = lax/disrupted FDP tendon which results in tension on lumbricals; during finger flexion, the cut/lax FDP tendon retracts toward palm, placing increase tension on lumbricals; they then extend the PIP ***one finger sticks out when attempting to hold an object
