Flexor digitorum profundus
Flexor digitorum profundus Definition
What is Flexor digitorum profundus? The Flexor digitorum profundus is the deep muscle in the hand and foot that helps bend the fingers and toes. The muscle belongs to the deep group of Antebrachial muscle in the anterior compartment. The Flexor digitorum profundus muscle has its origin in:
Flexor digitorum profundus Insertion
The muscle has its point of insertion in the anterior surface of the base of fingers’ distal phalanges – the common muscle group for the little, middle and ring fingers, with many links between the 3 tendons.
Flexor digitorum profundus Function
This muscle is involved in flexing all the joints of the digits and wrists.
Flexor digitorum profundus Innervation
It is supplied by the ulnar and median nerves T1 and C8. From proximal to distal, this muscle gets its blood supply from the following areas:
The proper and the common palmar digital arteries provide the distal tendons of this muscle with blood supply. The deep palmar arch, thorough the palmar metacarpal arteries, also supply blood to the muscle’s distal tendons.
Flexor digitorum profundus Tendon
The Flexor digitorum profundus tendon, which helps flex the DIP joint, affixes to the base of the distal phalanx. Disinsertion of the tendon can occur in case of a blunt trauma. In such cases, physical Flexor digitorum profundus test shows incapability of distal phalanx flexion. Radiograph might show a small bone chip. There can be indications of referral for surgery. In athletes, avulsion injuries of this tendon are common.
Flexor digitorum profundus Injury
Cases of Flexor digitorum profundus injury are common. The complications that are experienced most frequently include:
Most of these tendon injuries occur due to accidental trauma. Other typical causes include:
Diagnosis involves physical exam, assessing skin integrity, inspection, neurovascular exam, finding traumatic arthrotomy evidence, malrotation or malalignment evidence (which can suggest an underlying fracture) or observing the limb’s resting posture of the hand for digital cascade assessment.
Treatment for Flexor digitorum profundus tendon injury can include both operative and non-operative measures. Flexor digitorum profundus treatment includes various measures, such as:
