It is in the anterior compartment of the forearm. It is sometimes considered to be the deepest part of the superficial layer of this compartment,[1][2] and sometimes considered to be a distinct, "intermediate layer" of this compartment.[3] It is relatively common for the Flexor digitorum superficialis to be missing from the little finger, bilaterally and unilaterally, which can cause problems when diagnosing a little finger injury.[4]
