What is a FDMA flap?
Background: The First Dorsal Metacarpal Artery (FDMA) Flap or Kite flap or Foucher’s flap is an island pedicle flap proximally based on the first dorsal metacarpal artery and veins (William C Pederson, 2011). A branch of radial sensory nerve is incorporated in the flap to make it a sensate flap.
What is the thumb flap called?
The advancement neurovascular flap of the thumb was originally described by the Erik Moberg in 1964 hence it is best known today as the Moberg flap. The Moberg flap is indicated for coverage of small-to-medium sized defects over the volar aspect of the distal phalanx of the thumb without the need of shortening length.
How many dorsal metacarpal arteries are there?
three
From the dorsal carpal network (dorsal carpal network) are given off three slender dorsal metacarpal arteries, which run downward on the second, third, and fourth Interossei dorsales and bifurcate into the dorsal digital branches for the supply of the adjacent sides of the middle, ring, and little fingers respectively.
What is a cross finger flap?
The cross-finger flap (CFF) is one versatile flap used to cover such defects. The donor finger to the thumb is classically described to be the index finger (IF). However, with the index finger being the second most important finger, it causes further debilitation of the already injured hand.
What is a Thenar flap?
The thenar flap is a satisfactory reconstruction technique for the treatment of extensive loss of the distal phalanx of the index and middle fingers. As we observed in this series of 20 patients, this flap is reliable and provides tissue that closely matches the missing finger pulp.
Where is the metacarpal vein?
Anatomical Parts The dorsal digital veins pass along the sides of the fingers and are joined to one another by oblique communicating branches. Those from the adjacent sides of the fingers unite to form three dorsal metacarpal veins which end in a dorsal venous net-work opposite the middle of the metacarpus.
What is a local flap reconstruction?
About Local Flaps A local flap is when your surgeon takes tissue from 1 part of your body (called the donor site) and moves it to the surgical site that needs to be covered (called the recipient site). Local flaps can be used for reconstructing different areas of the body.
What is a thenar flap?
What is neurovascular island flap?
The FDMA flap is a neurovascular island flap that transfers skin from the dorsum of the index finger. The blood supply comes from the FDMA and its ulnar branch. The FDMA originates from the radial artery between the extensor pollicis longus (EPL) tendon and the bony apex of the first webspace (Fig. 73.8).
How long does it take for a severed finger to heal?
Aftercare and recovery Most minor finger cuts heal within 2–4 weeks. Deeper cuts or those requiring medical attention or surgery will take longer to heal.
What is a dorsal vein?
The deep dorsal vein of the penis drains oxygen-depleted blood away from the glans, which is the external head of the sexual organ. This vein runs the length of the shaft and it eventually flows into the prostatic venous plexus near a man’s prostate gland.
What are metacarpal veins?
The palmar metacarpal veins (or volar metacarpal veins) drain the metacarpal region of the palm, eventually draining into the deep veins of the arm. Palmar metacarpal veins. Details. Drains to. deep palmar venous arch.
Is dorsal aorta same as aorta?
Arteries to the trunk The dorsal aorta traverses the longitudinal axis of the body ending in the caudal peduncle anterior to the caudal (tail) fin. While this entire vessel is often referred to as the dorsal aorta, posterior to the peritoneal cavity, it is technically the caudal artery (CA).
What happens to dorsal aorta?
Dorsal aortae, the first functional intra-embryonic blood vessels, arise as two separate bilateral vessels in the trunk and undergo lateral-to-medial translocation, eventually fusing into a single large vessel at the midline. After this dramatic remodeling, the dorsal aorta generates hematopoietic stem cells.
What is the first dorsal metacarpal artery family of flaps?
The first dorsal metacarpal artery family of flaps belongs to this last category. These flaps can be performed in different ways, as a racquet, as an island flap, and as a bilobed flap including the second metacarpal artery, among others.
What are the surgical options for the treatment of metacarpal artery flaps?
Many different surgical options have been described for the treatment of these serious lesions, including microsurgical flaps, such as toe to hand flaps, local flaps, and distant pedicled flaps. The first dorsal metacarpal artery family of flaps belongs to this last category.
How do you do a FDMA flap?
FDMA, first dorsal metacarpal artery. To perform the FDMA flap as an island, 8 the first step is to identify the artery with a Doppler’s probe, the path is then marked with a needle. The flap is outlined on the dorsum of the index finger, the width and length of the flap must match the thumb defect.
What are the different types of flaps used in hand surgery?
These flaps can be performed in different ways, as a racquet, as an island flap, and as a bilobed flap including the second metacarpal artery, among others. The aim of the following article is to review the basic concepts involved in the use of these flaps in reconstructive hand surgery.
