There was normal (5/5) motor strength of the right APB, opponens pollicis, FPL, flexor digitorum profundus
D2D3 (index and middle fingers), extensor indicis, and EPL.
If the fracture is due to the avulsion of flexor digitorum profundus
, this is termed a Jersey fracture (Shabat et al 2004).
Zone II flexor digitorum profundus
tendons were isolated and transected as just described.
The belly on the medial aspect was larger and was arising from the medial margin of the olecranon process, proximal two thirds of posterior border of ulna, an aponeurosis which is common for FCU, extensor carpi ulnarismuscle and flexor digitorum profundus
muscle and intermuscular septum between it and flexor digitorum superficialis muscle.
flexor digitorum profundus
and the tendons that inserts onto the digits, with one or two palmar sesamoids embedded in it (this extension has been called the flexor plate by Haines, 1950).
The extrinsic muscles included the deep and superficial finger flexors: flexor digitorum profundus
(FDP) and flexor digitorum superficialis (FDS).
Also called Jersey finger, it usually involves the flexor digitorum profundus
The tiny lumbricals provide muscular bridges and harmonise the functions between lateral band interphangeal extensor mechanism and flexor digitorum profundus
, a unique occurrence which may have importance in adjusting the position of finger joints when using the hands.
We would also like to take this opportunity to clarify our recommendation in Case 4, in which the patient had Jersey finger, caused by traumatic avulsion of the flexor digitorum profundus
from the distal phalanx.
The median nerve runs down the anteromedial aspect of the arm but first gives rise to the anterior interosseous nerve, which descends on the interosseous membrane between the flexor digitorum profundus
(FDP) and flexor pollicis longus (FPL).
The ulnar nerve, after descending in the forearm between the flexor digitorum profundus
and flexor carpi ulnaris muscles, pierces the deep fascia and enters the wrist through the Guyon's canal.
In addition to AHFPL, in one case an additional muscle belly was observed and identified as accessory head of flexor digitorum profundus
and both were arising as common belly from the undersurface of FDS (Fig.
