Vogel describes an instance of this nature, in which the long flexor of the thumb was torn off with that digit.

In the Surgical Museum at Edinburgh there is preserved a thumb and part of the flexor longus pollicis attached, which were avulsed simultaneously.

Nunnely has seen the little finger together with the tendon and body of the longer flexor muscle avulsed by machinery.

Stone details the description of the case of a boy named Lowry, whose left thumb was caught between rapidly twisting strands of a rope, and the last phalanx, the neighboring soft parts, and also the entire tendon of the flexor longus pollicis were instantly torn away.
There was included even the tendinous portion of that small slip of muscle taking its origin from the anterior aspect of the head and upper portion of the ulna, and which is so delicate and insignificant as to be generally overlooked by anatomists.

There was great pain along the course of the tract of abstraction of the tendon.
Pinkerton describes a carter of thirty-one who was bitten on the thumb by a donkey.
