Abstract

Background

Avulsion of the flexor digitorum profundus tendon is a common injury to the hand that virtually always requires surgical repair for restoration of normal finger function.

Case Description

We report a case of a Type III flexor digitorum profundus tendon avulsion in which the patient refused surgery yet attained nearly full active ROM and an excellent functional result via the formation of a pseudotendon, as observed on MRI obtained 2.5 years after the initial injury.

Literature Review

There are no reported cases of restoration of normal finger function after pseudotendon formation in a flexor digitorum profundus tendon avulsion injury.

Purposes and Clinical Relevance

This case shows the potential for pseudotendon to not only form but have adequate tensile strength to restore function in certain types of flexor tendon injuries.
