Secondary coverage of the hand using a dorsalis pedis plus first web space free flap.

Traditionally, severe degloving injuries of the hand have been treated with random abdominal or pedicled groin flaps, which offer good cutaneous coverage but do not provide sensibility. The authors present the results of the application of an extended dorsalis pedis plus first web space of the foot flap to resurface the hands of five male patients who had been treated originally with random abdominal or pedicled groin flaps. The reported flap has the advantage of providing the patient with up to three different nerve territories, aiding in a better functional use of the hand.     

Combined ischemic preconditioning and laser Doppler measurement for early division of pedicled groin flap.

OBJECTIVES: The main disadvantage of the pedicled groin flap for hand reconstruction is the long period of immobilization required. Early division of the pedicled groin flap is desirable for both patients and surgeons. The aims of this study were to investigate whether ischemic preconditioning can effectively accelerate the neovascularization of the junction between the donor and recipient sites in the pedicled flap, and the most objective method of judging the timing of early division of the pedicled groin flap. This report is the first prospective study to use ischemic preconditioning for early division of pedicled cutaneous flap combined with laser Doppler measurement. METHODS: The severe hand injuries of 12 patients were reconstructed by using the pedicled groin flap method. The ischemic preconditioning program was prospectively performed as scheduled for 5 to 7 days postoperatively. The pedicled groin flap was monitored with laser Doppler when the flap was elevated, inset, with clamping and nonclamping postoperatively. RESULTS: Eleven of the 12 pedicled groin flaps were divided safely and survived completely. Only one pedicled groin flap with a simultaneous harvest of iliac bone graft had partial flap loss, giving a success rate of 90.1%. CONCLUSION: With ischemic preconditioning, the pedicled groin flap can be safely divided postoperatively at a mean period of 8.4 days according to the laser Doppler measurement, especially when the perfusion unit ratio of clamping over nonclamping reaches more than 36.6%.

Treatment of avulsion injury of three fingers with a compound thoracodorsal artery perforator flap including serratus anterior fascia

Complete degloving injury of three digits not amenable to revascularization may leave poor cosmetic and functional results. We used a compound thoracodorsal artery perforator (TDAP) flap in a 34‐year‐old, right‐handed, male worker with traumatic degloving injury. The flap consisted of a thin nonbulky skin component isolated on two perforators in combination with serratus fascia, both pedicled on the thoracodorsal vessels. The mobility of the two flap components allowed the palmar and dorsal part of the fingers to be reconstructed without relying on multiple flaps or anastomoses. The skin component of the TDAP flap was transferred to the palmar defect, the serratus fascia flap to the dorsal part of the fingers and sutured loosely. Coverage of the serratus anterior fascia was done with split‐thickness skin graft. Both components of the flap survived completely. One month after the first operation, the surgical syndactyly between middle and ring finger was separated, one month later the syndactyly between the ring and little finger. Good coverage of the soft tissue defects with good function could be achieved. There were no donor‐site problems. Therefore, we consider the compound TDAP flap as a useful method that provides functional and cosmeticcoverage of severe avulsion injury of multiple digits. © 2009 Wiley‐Liss, Inc.

Inferior extension of the groin flap based on the descending branch of the superficial circumflex iliac artery

The authors present a groin flap which was extended inferiorly and included the descending branch of the superficial circumflex iliac artery (SCIA) as a new alternative technique. Little research has been previously done on the descending branch of the SCIA, but the authors found clinically that this small branch was consistently present, and decided to make use of it to extend the groin flap inferiorly. The procedure extending the groin flap was successfully applied in three patients, one with a degloving injury of the leg, and two with progressive hemifacial atrophy. The extended portion was elevated as an island flap based on the descending branch in the patient with the degloving injury. Results revealed that this technique added a new axial portion located on the upper median thigh to the vascular territory of the conventional groin flap, and could be used to make a two-island groin flap.

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.     

Lower extremity reconstruction with the anterolateral thigh flap

The versatility and location of the anterolateral thigh (ALT) flap make it well suited for lower extremity reconstruction. The purpose of this study was to evaluate surgical and functional outcomes by specific anatomic regions in the lower extremity to better define the role of the ALT flap in lower extremity reconstruction. A retrospective review of patients undergoing lower extremity reconstruction with an ALT flap between July 2002 and December 2010 was performed. Total 46 patients underwent lower extremity reconstruction with an ALT flap, of whom 29 (63%) had a pedicled flap and 17 (37%) a microvascular free flap. Defects were located in the hip/buttocks (n = 8), groin (n = 13), thigh (n = 8), knee (n = 5), leg (n = 6), and foot/ankle (n = 6). The mean postoperative follow-up was 4 months. Total flap loss occurred in two patients (4%). There were 11 recipient site complications (24%). The most common complication was recipient site seroma, which occurred in five patients (11%), all of whom had hip/buttock or groin defects. Overall, 38 patients (83%) returned to their preoperative functional status. The ALT flap is an effective method of lower extremity reconstruction. It can be performed as a pedicled or free flap, with good surgical and functional outcomes.     

The Y-shaped hypogastric--groin flap

We present a technique of providing complete skin cover for total degloving injuries of the hand and distal third of the forearm. This involves the use of a Y-shaped hypogastric groin flap. The proximal portion of the Y is tubed allowing the distal portion of each flap to be applied to the dorsal and volar surfaces respectively. This technique allows complete skin cover of both surfaces and yet retains the advantages of the groin flap in that it still has a long pedicle allowing the hand to be put through a full range of motion, speeding rehabilitation.     

Groin flap immobilization by axillary brachial plexus block anesthesia

Pedicled groin flaps are still widely used as soft tissue coverage in hand surgery. Various methods have been described for immobilization of flaps, such as Ace wraps, plaster, and external fixators. The hands of 5 females and 12 males, totaling 17 patients, with severe injury were reconstructed with groin flaps between 2001 and 2005. Patients were operated on under a combination of axillary block and general anesthesia. Motor block effect of axillary anesthesia was used for immobilization of the upper extremities at groin flap coverage. A combination of axillary brachial plexus block plus general anesthesia had advantages in the prevention of pedicle tension or torsion during the initial recovery period. Reduction of general anesthesia time and improvement of postoperative pain were also observed. Axillary brachial plexus block and general anesthesia are a preferred combination for patients undergoing groin flap operations.     

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.

Pedicled anterolateral thigh flap for contralateral groin composite defect

Pedicled anterolateral thigh flap has been well described for ipsilateral groin defects. Its versatility depends on the intact femoral vessels. When the external iliac and the femoral vessels are absent, especially secondary to wide surgical tumour ablations in the groin region, ipsilateral ALT flap is not an option. Free flaps also are difficult because of lack of recipient vessels. We report a case of composite groin defect following wide resection of recurrent liposarcoma along with encased vessels which was covered with a pedicled anterolateral thigh flap from the opposite thigh. The technique of lengthening the vascular pedicle and medializing the pedicle, to effectively increase its reach to the contralateral anterior superior iliac spine without vascular compromise, is described.     

A bilobed groin flap for coverage of traumatic injury to both the volar and dorsal hand surfaces

BACKGROUND:

There are many methods available for coverage of both the volar and dorsal hand surfaces in traumatic injury. All of these surgical procedures allow for ample coverage of the defect, but have the major drawback of needing multiple donor sites. In the present report, a case of a complex crush injury to the hand in which both volar and dorsal surfaces received traumatic injury is presented. A bilobed groin flap pedicled on the superficial circumflex iliac artery was fashioned to cover the entire defect. Like many other described flaps, the bilobed groin flap resulted in a favourable functional and cosmetic result for the patient, but with the unique advantage of requiring a single donor site.

METHODS:

A bipedicled groin flap was raised from distal to proximal, and the flaps inset onto both the dorsal and volar hand defects.

RESULTS:

The patient regained adequate function of his hand, and was able to return to work full-time as a manual labourer.

CONCLUSION:

The bilobed groin flap appears to be a valuable option for covering complex hand injuries involving both the volar and dorsal surfaces of the hand.     

Combined multi-lobed flaps: A series of 39 extensive hand and multi-digit injuries one-staged reconstructions using modified designs of ALT,DPA and chimeric linking flaps

IntroductionThe use of multiple small flaps linked in a “chain-linked” flap microanastomosed chimeric system is recommended in distal hand and digital defects reconstruction. The aim of this study is to demonstrates our experience utilizing microsurgical fabrication, multi-lobed and linking combined flaps for the reconstruction of hand degloving injuries with complex multidigit soft tissue defects.MethodsMicroanastomosed chimeric flap systems using ALT and DPA modified designed flaps were combined in five selections to cover extensive soft tissue defects involving the hands and multiple digits of 39 patients (M:F − 36:3) from October 2009 to February 2013. Five different microsurgical combined chimeric flap systems utilised in extensive hand and multidigit injuries; innervated ALT flaps, multilobed DPA flaps, innervated ALT flap with multilobed DPA flap, innervated ALT flap with sensate ALT flap and bilobed ALT flap with multilobed DPA flap. All DPA donor sites were reconstructed using free ALT flap and anterior tibial artery propeller flap.ResultsThirty-nine combined free flap extremities reconstructions on 39 patients (M:F − 36:3) with average age 28.5 (18–45) years sustained traumatic degloving injuries, 24 from road traffic accidents and 15 from industrial devices. Five different designs of combined multi-lobed flaps have be successfully used without any peri-operative complications. Average follow-up of 12 months, all flaps survived without complications. Operated extremities showed favorable functional recovery with restoration of the diminished protective sensation on the flap through reinnervation. All flaps survived uneventfully with coverage matching the texture and color of the recipients. Donor sites healed without complication.ConclusionThe microsurgical fabrication of chimeric ALT flaps and multilobed DPA flaps is a valuable alternative for the reconstruction of hand degloving injury with complex multidigit soft tissue defects.Level of evidence: Level IV, therapeutic study.     

Microdissection thinning of a pedicled deep inferior epigastric perforator flap for burn scar contracture of the groin: case report

A severe burn scar contracture of the groin in a 25-year-old woman was successfully reconstructed with microdissection and thinning of a pedicled deep inferior epigastric perforator (DIEP) flap. This perforator flap is a relatively thin cutaneous flap, but may still require secondary defatting procedures, especially when used for coverage of mobile anatomic areas such as the groin and axilla. A deep inferior epigastric perforator flap was radically thinned by excising the subcutaneous fatty layer very carefully under loupe magnification, to preserve the subdermal vascular plexus. One year after surgery, the patient can abduct and rotate the hip freely without limitation.     

Pedicled posteromedial thigh (PMT) flap: A new alternative for groin defect reconstruction

The posterior medial thigh is mainly vascularized by the profunda femoris artery (PFA), which nourishes the adductor magnus muscle and overlying skin, to supply a number of perforators that can potentially be used as pedicles for local perforator flaps. Here we present two cases utilizing the pedicled posteromedial thigh flap (PMT) to reconstruct the groin defects. Two patients underwent resection for metastatic malignant melanoma resulting in large defects of the groin with exposure of major inguinal vessels; the dimensions of the skin defects were 15 cm × 5 cm and 16 cm × 6 cm, two ipsilateral pedicled PMT flaps were designed to cover the defects. The pedicled PMT flaps were based on perforators arising from the PFA and were transposed through a submuscular tunnel into the defect. The postoperative course was uneventful and the wounds were reconstructed successfully. The pedicled PMT flap may be an option for reconstruction of groin defects and could be incorporated into the armamentarium of the reconstructive microsurgeon. © 2015 Wiley Periodicals, Inc.

Pedicled free flap for burn scar contracture of a hand

 The treatment of a severe post-burn contracture of the left hand is presented. A free scapular flap was transplanted to the inguinal area and then used to release the contracture in the manner of a pedicled groin flap. The advantages of this method are that it can be utilized regardless of the condition of the recipient site, and the major vessels of the hand remain intact.
