The artery is located in the groove between radial of the body of the second metacarpal bone and the ulnar head of the first interosseous muscle. A teardrop skin pedicle was used to reduce the tension of the flap pedicle. Arms, Groups and Cohorts . RESULTS: The distal cutaneous branches originating from the dorsal metacarpal arteries were observed in all cases; these were located an average of 1.2 cm proximal from the metacarpophalangeal joint. Background: The proper palmar digital arteries arise infrequently from dorsal metacarpal arteries. The skin flap was designed on the radial side of the proximal phalanx of the index finger based on the ulnar and radial branch of the FDMA and a sensory branch of the superficial radial nerve. The hand is examined to determine the anatomy of the loss, suppleness of joints and soft tissues and the potential requirements for reconstruction. The second metatarsal can provide support for reconstruction of a defect when metacarpal is missing in the hand. A branch of the basilar artery; it runs dorsally along the posterior edge of the pons and supplies blood to the hindbrain, the superior and middle cerebellar peduncles, and portions of the ventral cerebellum. reverse first dorsal metacarpal artery flap was chosen. Following the first description of the dorsal metacarpal artery by Holevich , Foucher and Brauna improved the technique and designed a sensate island flap raised on the first dorsal metacarpal artery flap with its concomitant veins and a sensory branch of the superficial radial nerve in 1979 . The results were compared with 25 patients treated by the conventional Foucher’s first dorsal metacarpal artery flap without nerve repair. Innervation. First dorsal metacarpal artery flap - Also known as the kite flap, this is another reconstructive option that can bring sensate skin to the injured thumb. We describe our clinical experience using a modified first dorsal metacarpal artery island flap innervated by the radial dorsal branch of the proper digital nerve and the terminal branch of the superficial radial nerve in 20 consecutive cases. at the metacarpal heads, they anastomose with the common palmar digital branches of the superficial arch; they perforate the interosseous spaces to anastomose with the dorsal metacarpal arteries; Dorsal arterial supply. First Dorsal Metacarpal Artery. The pedicle includes the ulnar branch of the first dorsal metacarpal artery, the dorsal veins, and the cutaneous branch … Define metacarpal artery. The location of the cutaneous branch of that artery is very critical for the removal of the flap. The flap is based on branches of the first dorsal metacarpal artery, included in the subcutaneous tissues of the pedicle. The proximal perforating branch of 2nd dorsal metacarpal artery enters the palm at the base of 2nd intermetacarpal space by passing between 2 heads of origin of 2nd dorsal interosseous muscle to contribute to the catella volaris proximalis while its distal perforating branch enters the palm at the distal end of 2nd intermetacarpal space helping formation of catella volaris distalis. Branches of the deep arch (from radial to ulnar) princeps pollicis. The dorsal aspect of the fingers is supplied by the dorsal cutaneous branches of the palmar digital arteries as well as the dorsal digital branches of the dorsal metacarpal artery and the dorsal cutaneous branches of the palmar digital artery. is technique gained popularity and was Open Access in all patients with a mean 2PD of 11.2 mm. Articles. Each of these arteries receive the corresponding volar metacarpal artery and then divide into a pair of proper palmar digital arteries .

This forms the palmar carpal arch to supply the carpal bones and their joints. 1 The usual origin and course of the second dorsal metacarpal artery. Nevertheless the presence of the first and the second dorsal metacarpal artery (DMA) is constant. The first dorsal metacarpal artery flap is a reliable, local, neurovascular island flap, offering good functional and esthetic outcomes (Fig 5). Thus the first dorsal metacarpal and dorsalis pollicis are primarily digital branches from posterior interossesous branch of the first intermetacarpal space; the later is a branch of dorsal carpal arch and has become a portion of the radial by anastomosis of that artery with the arch. At the phalanges, the tendon forms a dorsal aponeurosis which is supplied by a digital branch of the first dorsal metacarpal artery. The need for any further soft tissue reconstruction is identified, such as a second skin or fasciocutaneous transplant or even a local flap . dorsal carpal artery is a branch of _________. The first dorsal metacarpal artery presented in 3 different patterns regarding its course: fascial, subfascial, and mixed. Littler neurovascular island flap.

The dorsal digito-metacarpal flap is a vascular island flap based on the dorsal digital artery and dorsal metacarpal artery. It commences at the bifurcation of the brachial, just below the bend of the elbow, and passes along the radial side of the forearm to the wrist. Wrist: The 2 main branches of the radial artery at the wrist are the dorsal carpal branch and the first dorsal metacarpal artery. Synonym(s): arteriae metacarpale dorsale [TA] This radial artery gives branches to the formation of the rete carpi dorsale and volare and another branch, which passes between the suspensory ligament and the large metacarpal bone. Type II (23.5%) originated from the perforating branch of the deep palmar arch at the bases of second and third metacarpal bones. The first dorsal metacarpal artery flap is a reliable, local, neurovascular island flap, offering good functional and esthetic outcomes (Fig 5). However, even 7. dorsal metacarpal artery, an arterior interosseous artery, and arising as a large direct branch of the radial artery. Pertinent anatomical knowledge regarding the It passes down the dorsal metacarpal groove and below the fetlock it is joined by the distal perforating metacarpal artery from the deep volar arch to form the volar common digital artery. The dorsal carpal arch (dorsal carpal network, posterior carpal arch) is an anatomical term for the combination (anastomosis) of dorsal carpal branch of the radial artery and the dorsal carpal branch of the ulnar artery near the back of the wrist.. The first dorsal metacarpal artery (FDMA) arises from the dorsal carpal arch and runs distally over the first dorsal interosseous muscle.2 Omokawa et al3 reported that the FDMA originated from either the dorsal branch of the radial artery at the anatomic snuffbox or the perforating branch of the deep palmar This vessel splits from the radial artery just before it courses between the two upper ends of the first Interosseous dorsalis. This flap was used as a fasciocutaneous flap or as a fascial flap. A) Relevant anatomy: The FDMA is a branch of the radial artery. Dorsal Carpal Arch. The first dorsal metacarpal artery (FDMA) flap is used mainly for reconstruction of thumb defects, although arc of rotation of this flap is wide enough to cover other areas such as two-thirds of the dorsum of hand on radial aspect, dorsal region over proximal phalanx of middle finger, and radial half of palm. A sensate first dorsal metacarpal artery flap, mobilized from the dorsum of the adjacent index finger and used as an island pedicle skin flap, can be useful for this purpose. Define metacarpal arteries, dorsal. The incision was sutured after hemostasis was achieved. Experimental: Surgical flap. Deep palmar arch - is located on the palmar surface of the bases of the metacarpals. Anastomosis with the corresponding ulnar branches gives rise to the deep and superficial palmar arches. To the index finger and the first dorsal metacarpal. Any traumatic injury or congenital absence requires a thorough preoperative evaluation by the microsurgeon. In 3 patients, the digital branch of the superficial radial nerve was coapted to the digital nerve. Extensive review of the literature has highlighted significant discrepancies regarding the nomenclature of the dorsal metacarpal arteries despite the anatomical findings first described as far back as 1911 remaining consistent. 3. The PPA has been used in reference to the first palmar metacarpal artery or simply the primary source of blood supply to the thumb . 1 The usual origin and course of the second dorsal metacarpal artery. Type I,(A) appears to be the most common one, with three vessels arising from a common trunk. The pedicle was carefully protected, and the flap was transplanted to the defective skin area. It anastamoses with the palmar carpal branch of the ulnar artery and the anterior interosseous arteries. Can be pedicled or free - To cover defects at the dorsum of the thumb - At the Ulnar aspect of the lateral thumb - Or also rarely at the tip of the thumb - Dorsal hand defects . one of the large terminal branches of radial artery. The first dorsal metacarpal artery (Image-1) arises from the radial artery just before it passes between the heads of the first dorsal interosseous. Antonyms for metacarpal artery. [25] reported retained sensation island flap. Keeping this in view, what are dorsal veins? Cutaneous branches of the second dorsal metacarpal artery were mainly clustered at three positions: 43.9, 61.2, and 72.1% in the distal second dorsal metacarpal artery, which was chosen as the flap pedicle with a cutaneous nerve to repair the skin defect in the hand and fingers of a patient.

The pivot point was located at the level of the middle point of the proximal phalanx, where the communicating branches between the proper palmar digital artery and the dorsal metacarpal artery exist. A global group of dedicated editors oversee accuracy, consulting with expert advisers, and constantly reviewing additions. It originates as one of the terminal branches of the radial artery at the bony apex of first web space where it passes deep to first dorsal interosseous muscle to enter the palmar space. Ege A, Tuncay I, Ercetin O. Foucher’s first dorsal metacarpal artery flap for thumb reconstruction: evaluation of 21 cases. The pedicle can be made narrow enough to close the pedicle donor site directly, as was done here. The dorsal carpal arch (dorsal carpal network, posterior carpal arch) is an anatomical term for the combination (anastomosis) of dorsal carpal branch of the radial artery and the dorsal carpal branch of the ulnar artery near the back of the wrist. It is made up of the dorsal carpal branches of both the ulnar and radial arteries. Views: 175 847. predominant supply is the deep branch of the radial artery. The plane containing the fourth dorsal metacarpal artery has been discussed widely in the literature.

Method 1) Line and draw ur surgery. However, the artery emerged from a common arterial trunk with the first dorsal metacarpal artery in 16% of the cases (Type II), but its course remained the same. There is an infrequent disposition of the first metacarpal artery which results in an anastomosis with the common palmar digital artery of the second space, forming an anastomotic system between the deep radial system and the superficial ulnar system. Plast Reconstr Surg. dorsal metacarpal artery. From there, the dorsal metacarpal arteries arise and travel down to supply the middle and smaller fingers with blood. Figure 2. Innervation: The dorsal branch of the ulnar nerve. Restoration of tactile sensation after reconstruction of a thumb pulp defect is import for hand function. Branches.—The branches of the radial artery may be divided into three groups, corresponding with the three regions in which the vessel is situated. -is completed medially by anastomosing with the deep branch of the ulnar a. This arch is commonly formed by the terminal dorsal carpal branch of the radial artery, supplemented by the dorsal carpal branches of the ulnar and posterior interosseous arteries. TE 3 (Shu-Stream Point) Chinese Name: Zhongzhu English Name Location: When the fist is clenched, the point is on dorsum of the hand between the fourth and fifth metacarpal bones, in the depression proximal to the fourth metacarpophalangeal joint. thumb. The behaviour of 21 such flaps, all raised in the form of an island, was that of a conventional axial pattern flap. This forms the palmar carpal arch to supply the carpal bones and their joints. This vessel also forms the base of the midphalangeal island flap and feeds the subcutaneous arterial network. In the dorsal dominant system, the first dorsal metatarsal artery gives rise to the digital artery to the second toe. 掌背动脉 . These variations do not influence the operative technique or flap survival. Sixty-seven percent of the third and the fourth dorsal metacarpal arteries is formed by anastomosis of the dorsal carpal artery and its deep palmar arch. palmar metacarpal arteries 1 there are three palmar metacarpal arteries. 2 branch off the deep palmar arch. 3 at the metacarpal heads, they anastomose with the common palmar digital branches of the superficial arch. 4 they perforate the interosseous spaces to anastomose with the dorsal metacarpal arteries.

A small .perforating branch joining the deep palmar arch. 2) First dorsal metacarpal artery: The perforating branches arise from the concavity of the deep palmar arch and run in the interosseous spaces 2-4. Uses. The cutaneous branches of the dorsal carpal arch anastomose with the cutaneous branches of the posterior interosseous artery (PIA) of the distal forearm, thus forming an additional axial cutaneous arterial network. This is a reliable, simple regional flap option which can potentially circumvent all the disadvantages mentioned earlier with the alternative dorsal metacarpal artery cannot be mobilized up to its origin at the dorsal arch because of the crossing over of the extensor tendons.7 Reverse dorsal digital or metacarpal flaps are reliable, with ample tissue available, and do not require the sacrificing of a digital artery. deep palmar arch anatomoses with ulnar artery through _______artery. This new flap is based on a direct cutaneous branch of the dorsal metacarpal artery. Dorsal carpal branch – Originates distal to the radial styloid and travels superficial over the scaphoid and anastomosis with the ulnar dorsal carpal branches to form the dorsal carpal arch. Dorsal Carpal Arch. First dorsal metacarpal artery flap is a fasciocutaneous flap in which the dorsal skin of the second finger is used on the proximal phalanx, whose skin island usually measures between 2 - 3 x 5 - 8 centimeters. Blood supply. After measuring the distance of improvement, the skin flap was transferred to the palmar side of the proximal phalanx of the right thumb. The first dorsal metacarpal artery flap reaches defects on the volar thumb tip, thumb dorsum, first web space, the MCP joint of the small finger, and even the wrist and carpal joints. The vascular anatomy of the dorsal aspect of the hand is variable. Il. Branches 1) Dorsal carpal branch: The dorsal carpal arch provides three dorsal metacarpal arteries which run over the second, third, and fourth interosseous spaces; each divides into two dorsal digital arteries for the adjacent sides of two fingers.

They also anastomose with common palmar digital arteries (from the superficial palmar arch), also via perforating arteries. The first dorsal metacarpal artery flap is a common method to cover skin defects of the thumb palmar in adult microsurgery. The innervation of all dorsal interossei is carried by the deep branch of ulnar nerve, derived from nerve roots C8 and T1. The second to takes its blood supply from a dorsal or plantar system, which varies by patient. We elevated 8 reverse-flow first dorsal metacarpal artery flap in 9 patients for soft-tissue cover of index fingertip injuries distal to distal interphalangeal joint with exposed bone. Synonym(s): arteriae metacarpale dorsale [TA] A series of 12 clinical cases is reported. In all cases, the first dorsal metacarpal artery flap technique was unable to be used because of injury. Dorsal carpal branch. The cutaneous perforator is very reliable and can almost always be found within the second through the fourth intermetacarpal spaces roughly 1 cm proximal to the metacarpal neck. The proximal connection occurs at the level of the metacarpal neck just distal to the juncturae tendinum between the DMCA and the dorsal perforating branch of … The reverse dorsal metacarpal artery (RDMA) is a time-tested option for the reconstruction of the same. The caliber of the dorsal metacarpal artery is similar to that of the proximal communicating branch and it received a minor contribution (smaller caliber) from the dorsal carpal arch in all specimens (Fig. Looking for metacarpal arteries, dorsal? According to these proportion as the snuff-socket, the perforator branch of the first dorsal metacarpal artery and a few tissues were retained as the pedicle of the skin flap.
