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.
FDS=
Flexor digitorum profundus, FDS= flexor digitorum superficialis.
Sonographic measurements of
flexor digitorum profundus tendons of the second, third and fourth fingers of the archers.
Kirner's deformity treated by distal detachment of the
flexor digitorum profundus tendon.
The extensor tendon inserts into the epiphysis only, whereas the
flexor digitorum profundus inserts into the metaphysis or spans both the epiphysis and the metaphysis (AlQattan, 1998).
The four lumbricals (flex metacarpophalangeal (MCP) joint and extend interphalangeal (IP) joint of each finger) arise from the tendons of the
flexor digitorum profundus and insert into the radial sides of each finger proximal phalanx.
Using microsurgical technique, the forepaw and hindpaw
flexor digitorum profundus (FDP) equivalent was dissected free of surrounding tissues.
There are four tendons of the flexor digitorum superficialis muscle going to fingers 2-5, responsible for flexing the middle joint of the fingers (Figure 1A), four tendons of the
flexor digitorum profundus muscle also going to fingers 2-5 responsible for flexing the distal joint of the fingers (Figure 1B), and one tendon from the flexor pollicus longus muscle going to the thumb to flex the thumb (Figure 1C).
On examination, her injuries included complex volar hand lacerations measuring up to 20 cm involving the flexor digitorum superficialis and
flexor digitorum profundus, a zone II avulsion of the ring finger and zone III avulsion of the small finger on the ipsilateral hand.
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).
This study was designed to outline the anatomy and MRI appearance of the normal ligaments and tendons in the hands including the UCL at the metacarpal phalangeal joint (MCPJ) of the thumb, the central slip, the terminal tendon, and the
flexor digitorum profundus (FDP) using cadaveric specimens and normal volunteers, review the common sports-related fingers and thumb deformity due to ligamentous and tendinous injuries, discuss the mechanisms of injuries, and illustrate the characteristics of MRI using the surgically proven cases of ligamentous and tendinous injuries.
