The anatomy of the flexor digitorum superficialis relevant to tendon transfers.
The flexor digitorum superficialis is a diagastric muscle with a proximal muscle belly from which the tendons to the index, ring and little fingers arise. These tendons are not independent and are not good motors for non-synergistic transfers, such as for finger extension. The muscle and tendon to the middle finger arise separately and are therefore more suitable for non-synergistic transfers.
