The Combined Use of a Pedicled Superficial Inferior Epigastric Artery Flap and a Groin Flap for Reconstruction of a Dorsal and Volar Hand Blast Injury

A hand blast injury case causing a large through-and-through composite tissue loss is presented. This injury resulted in a dorsal and a palmar hand defect with segmental bone loss. Soft tissue coverage of both dorsal and palmar wounds was achieved by two separate pedicle flaps with pedicles closely arising from the femoral artery: a superficial inferior epigastric artery (SIEA) flap and a groin flap. Simultaneously, a large iliac corticocancellous bone graft was harvested from the same incision to be used for the wrist fusion procedure. This approach uses two separate pedicled flaps with robust independent blood supply to cover simultaneously a dorsal and a volar hand wound. A large through-and-through hand defect can be reconstructed readily with this approach, and it is associated with much less perioperative morbidity compared to free composite tissue transfer options. The dissection of both the groin flap and the SIEA flap is straightforward and can be easily performed by a single surgeon. The combined use of these two flaps allows stable coverage of sizable dorsal and palmar wounds of the hand.     

Combined medialis pedis and medial plantar fasciocutaneous flaps for coverage of soft tissue defects of multiple adjacent fingers

Soft tissue defects of adjacent multiple fingers covered by a single large flap require secondary separation of the flap into each finger. Such covering obstructs independent motion of injured fingers until the single large flap is separated. This report describes the technique of combined medialis pedis and medial plantar fasciocutaneous flaps for reconstructing soft tissue defects of multiple adjacent fingers. Three male patients (age range, 18–33 years) underwent soft tissue reconstructions of multiple adjacent fingers with combined flaps. Injuries involved three adjacent palmar fingers, two adjacent palmar fingers, and two adjacent dorsal fingers. Average sizes of the combined flaps were 4.2 × 4.0 cm for the medialis pedis flap and 3.0 × 1.8 cm for the medial plantar fasciocutaneous flap. All flaps survived without vascular complications, and donor sites healed uneventfully. All patients experienced excellent recovery of range of motion for the reconstructed fingers. In conclusion, combined flaps may offer an alternative for coverage of soft tissue defects that involve multiple adjacent fingers. © 2014 Wiley Periodicals, Inc. Microsurgery 34:454–458, 2014.

Refinements in hand coverage with microvascular free flaps.

The specialized tissue requirements or dorsal and palmar skin are analyzed and options for full-thickness replacement outlined in detail. Thoughtful and accurate preoperative planning is the key to success. Dorsal coverage with a variety of pedicled and free fasciocutaneous flaps are quite satisfactory. Palmar coverage is more difficult and the need for sensation more critical. Free vascularized temporoparietal fascial flaps covered with full-thickness skin grafts are currently the treatment of choice for most complex wounds.     

Combined medialis pedis and medial plantar fasciocutaneous flaps based on the medial plantar pedicle for reconstruction of complex soft tissue defects in the hand

The reconstruction of complex soft tissue defects in hands remains a difficult challenge in reconstructive surgery. In this report, we introduce a combined medialis pedis and medial plantar fasciocutaneous flaps supplied by the lateral and medial branches of the medial plantar artery, which allows a one-stage reconstruction of multiple soft tissue defects in hand. Three combined medialis pedis and medial plantar fasciocutaneous flaps were transferred for repair of the soft tissue defects including palmar and dorsal areas of hand, thumb pulp, and the dorsum of index finger in three patients. All three flaps survived uneventfully with coverage matching the texture and color of the recipients. The donor sites healed without complication. The experience from these cases proves that the combined medialis pedis and medial plantar fasciocutaneous flaps based on the medial plantar pedicle would be a valuable alternative for the reconstruction of complex soft tissue defects in the hand.     

Reconstruction of through and through gunshot injuries of the hand with a double skin paddle reverse-flow forearm radial flap. Two case reports

The authors report two cases of gunshot wounds to the hand treated with a double skin paddle reverse-flow forearm flap. The two cases, male and female, were due to a self-inflicted rifle injury. The wounds were severe and extensive with full-thickness palmar and dorsal skin, tendon, muscle, bone, vessel and nerve losses. Treatment was performed in a single stage with skeletal stabilization, bone grafting and nerve and tendon reconstruction. The double palmar and dorsal skin defect was reconstructed with a double skin paddle reverse-flow forearm flap which was routed through the hand wound. The forearm flap is the sole way, free flaps excepted, to achieve reliable hand dorsal and palmar coverage in a single stage. In addition, this technique simplifies the reconstruction by using a local flap and allows better management for healing and rehabilitation as compared to a multiple flap procedure.     

Repair of avulsion injury of the whole hand with single-stage transfer of five combined tissues: case report

The authors present a 32-year-old man with an entire left hand avulsion injury. This was repaired in one stage with five free-tissue transfers, a combination of a left hallux wrap-around flap for thumb reconstruction, bilateral second toes for middle and ring finger reconstruction, and bilateral femoral anterolateral flaps for coverage of the injured hand at the palmar and dorsal aspects. All the transfers survived uneventfully. Due to enlargement of the flaps and narrowness of the first web space, three further surgical procedures were subsequently carried out. Over a 2-year follow-up, a satisfactory appearance of the reconstructed hand and functional restoration were obtained.     

Vascular basis of dorsal digital and metacarpal skin flaps

We studied the vascular anatomy of dorsal digital skin flaps and the vascular anastomoses between the dorsal cutaneous branch of the palmar digital artery (PDA) and the dorsal digital branches (the terminal branches) of the dorsal metacarpal artery (DMA) at the level of the proximal phalanx. Eight fresh cadavers (16 hands) were injected with a lead oxide-gelatin mixture. Our radiographic assessment revealed that there were 2 sources of the arterial supply to the dorsum of the digit, the dorsal digital branches of the DMA, and the dorsal cutaneous branches of the PDA. These branches anastomose with each other. A flap including the territory of the dorsal cutaneous branches of the PDA and a part of the territory of the DMA can be harvested on the dorsal aspect of the proximal and middle phalanges. The extended neurovascular island flap, based on the PDA and the dorsal branch of digital nerve, can be transposed to the volar surface of an adjacent finger resurfacing the entire length of the digit.     

Treatment of complex hand trauma using the distal ulnar and radial artery perforator-based flaps

SUMMARY: The clinical value of distal ulnar or radial artery adipofascial perforator flaps is shown in a series of 30 patients with severe hand and wrist injuries and major soft tissue defects requiring coverage. There were 22 men and 8 women, aged 16-73 years. The defects were dorsal and/or palmar, with or without transpalmar or transcarpal amputation, or amputation of the thumb and/or the digits. Tendon injuries have been treated primarily or secondarily, or reconstructed using silicon rods. In all cases, after surgical debridement of the wound, reconstruction of the defect was done using distal ulnar (21 patients, in 3 patients primary reconstruction) and distal radial artery (11 patients; in 2 patients primary reconstruction and in 2 patients after necrosis of distal ulnar perforator flap) adipofascial perforator flaps. Minimum follow-up was 6 months. Two ulnar flap showed partial necrosis and were revised successfully by distal radial adipofascial perforator flaps. One radial and one ulnar flap showed 50% and 60% necrosis, respectively, and were revised by groin flaps. All donor sites healed uneventfully. Functional and cosmetic result was very good in 15 patients and good or satisfactory in the remaining. Range of motion of the wrist and hand joints was almost within normal limits (less than 25 degrees extension or flexion deficits). Distal ulnar and radial artery adipofascial perforator flaps for traumatic defects of the hand and wrist offer several advantages compared to other local flaps; they are easy to obtain and cover effectively both dorsal and palmar defects without significant functional deficits or donor site complications to the upper limb.     

HS10FLAP COVERAGE IN UPPER LIMB INJURIES

The severely of skin loss and the options of resurfacing is determined by taking into account the following factors. 1) The size & location of the defect, 2) The depth of the defect and the quality of the tissue bed, 3) The extent of exposed vital structures, 4) The associated bone and other tissues injuries, 5) The availability of donor skin flap. The size of the defect is the most important factor in choosing a resurfacing option. The size can be categorized into small, medium and large. A small defect is one that is less than 5 cm² in size, a medium defect is between 5 to 15 cm², and a large defect is greater than 15 cm². Local flaps are usually sufficient to cover small defects <5 cm². These are advancement flaps or rotation and transposition flaps. Regional flaps are indicated to resurface these medium‐sized defects 5 to 15 cm². The donor is within the same region of the hand, from one of the digits or from dorsum and palmar surfaces of the hand. It is usually based on vascular or NV pedicles. Large defects >15 cm² will need larger flaps for coverage. These large flaps are pedicled distant flaps and free flaps. In these severe injuries, there is usually associated bone and soft tissues injuries. These injuries can be reconstructed as a single stage combined reconstruction or multi‐staged reconstructions. The resurfacing should always be given priority.     

Distal radial and ulnar arteries perforator-based adipofascial flaps for covering hand traumatic defects

AIM: The clinical value of adipofascial flaps based on distal ulnar or radial-artery perforators is demonstrated in a series of 14 patients with severe hand injuries and significant soft tissue defects requiring coverage. MATERIAL AND METHODS: There were 10 male and 4 female patients, aged between 23 and 72 years. The defects were 7 dorsal, 4 palmar, 1 combined dorsal-palmar, and 2 with thumb or total digit amputation. In the patients with a dorsal defect, the extensor tendons were intact in 2 cases, reconstructed in 2 cases, and reconstructed in 3 cases using silicon rods. Following debridement, a fascial flap based on a distal ulnar (12) or radial (4, 2 primarily and 2 secondarily) artery perforator was fashioned and used to cover the defect. A split thickness skin graft was used to cover the defect and the hand was immobilized for 2 weeks. RESULTS: All cases were followed up for at least 6 months. The donor and recipient sites healed uneventfully, and the functional result was very good in terms of wrist and hand joint range of motion, which approximated the normal rates. The extension or flexion deficit was less than 25 degrees. The esthetic result was satisfactory. Two ulnar flap partial (involving approximately 35% of the area) necroses have been treated using reversed radial-distal perforator flaps. CONCLUSION: The described fascial flaps offer several advantages over other local flaps, and are rather easy to perform and cover effectively both dorsal and palmar hand defects without causing significant functional deficits to the upper limb.     

Surgical anatomy of the dorsal face of the hand and the wrist

The anatomical knowledge of the dorsal aspect of the hand has been enriched these last years by a more surgically applied approach, especially of that of its integument and blood supply. The vascularization of the superficial nerves, the anastomoses between the dorsal and palmar arterial networks has allowed designing new flaps, ante- and retrograde, usable in the coverage of more and more distal defects. The extensor apparatus shows many anatomic variations, often asymptomatic, except the extensor digitorum brevis manus muscle, which can mimic a mass at the dorsal aspect of the hand.     

Arterial anatomy and clinical application of the dorsoulnar flap of the thumb.

After injection of stained latex at the brachial artery, the arterial supply of the dorsal aspect of the thumb was studied by light microscopy in 25 cadavers. An artery, located on the dorsoulnar side and connecting the head of the first metacarpal with the dorsal arcade of the proximal nail fold, was found in all dissections. We report the results of the anatomic study and the clinical applications of a dorsoulnar skin flap that can be raised on its artery with a distal pedicle. Clinical experience is based on 32 flaps. In 25 cases this flap was used for distal skin loss coverage (palmar or dorsal) of the thumb as an island flap. In 7 cases it was used for reconstruction of the finger pulp (5 index and 2 middle fingers) in the form of a cross-finger flap.     

Intrinsic flaps in the hand

Advances in anatomical research have created the base for a vast variety of flaps that can be raised in the hand. They are either based on the palmar arterial system or on the dorsal vascular system, which is fed by either perforating vessels from the palmar side or the dorsal arterial system nourished by dorsal carpal arterial network. The majority of small to moderate size defects in the hand can be reconstructed with these types of flaps.     

Reverse Radial Forearm Fascial Flap With Radial Artery Preservation

The reverse radial forearm fascial (RRFF) flap is widely used in soft-tissue reconstruction of the hand. The traditional RRFF flap incorporates the radial artery from the forearm and is perfused by retrograde flow through the palmar arch. In patients with an abnormal Allen test because of an incomplete palmar arch, the traditional RRFF flap is contraindicated unless a vein graft is used to reconstruct the radial artery. A simpler alternative approach for hand reconstruction in such patients is a distally based RRFF flap based on radial artery perforators, which preserves the radial artery. We used RRFF flaps based on radial artery perforators in five patients who had palmar or dorsal soft-tissue loss. All five recovered full hand function, and only one had any complications (full-thickness skin graft loss at recipient site). The RRFF flap based on distal radial artery perforators is suitable for thin coverage of soft-tissue defects in hands with either a complete or an incomplete palmar arch.     

The reverse radial forearm flap for soft tissue reconstruction of the wrist and hand

Soft tissue defects of the upper extremity must be carefully assessed to determine the most appropriate method of coverage. Direct closure and local flaps represent the most basic techniques on the reconstructive ladder; however, they are inadequate for large or complex defects. Split thickness skin grafts are appropriate for granulating wounds with a bed of vascularized tissue; however, if there is an exposed joint or bone devoid of periosteum or tendon devoid of paratenon, there will be insufficient neovascularization, and the graft will inevitably fail. The reconstructive hand surgeon must then pursue more complicated techniques for wound coverage based upon knowledge of the available pedicled and free flaps. The reverse radial forearm flap potentially offers thin, mobile skin with similar characteristics to the skin over the dorsum of the hand. This flap is more versatile than the groin flap and probably more reliable than the posterior interosseous artery flap for coverage of moderate-sized defects of the dorsal or palmar wrist and hand and is specifically indicated for coverage of degloving injuries of the dorsal wrist and hand, after release of thumb-index finger web space, and for coverage of amputations of the thumb in preparation for toe-to-thumb transfer.     

Eleven consecutive combined latissimus dorsi and serratus anterior free muscle transplantations

We reviewed our experience with 11 consecutive combined latissimus dorsi and serratus anterior free-muscle transplantations from 1980 to 1990. All 11 flaps were successful and there was minimal morbidity. This combined muscle flap is ideal for soft-tissue coverage in extensive lower extremity wounds, in mutilating hand injuries with dorsal and palmar defects, and in situations when a long vascular pedicle is needed to get out of the "zone of injury."

Couverture d’une perte de substance palmaire par un lambeau synovial des fléchisseurs superficiels des doigts

Post-traumatic palmar soft tissue defects are a difficult problem in plastic surgery and many techniques have been described. We report the case of a 41-year-old patient with a large palmar soft tissue defect of the right hand due to a work accident. The classical flaps used in this indication were not usable. So, we chose the synovial flap of the Flexor digitorum superficialis to cover this palmar defect. We discuss the coverage possibilities for a hand palmar defect in emergency, and the use of the synovial flap in this indication. This case report shows that the synovial flap could be an option for the coverage of palmar soft tissue defects.
