The gluteal fasciocutaneous rotation-advancement flap with V-Y closure in the management of sacral pressure sores

The sacral region is one of the most frequent sites of pressure sore development, and local flaps in the gluteal region are usually preferred when surgical closure is needed. The authors used the gluteal fasciocutaneous rotation-advancement flap with V-Y closure to manage sacral pressure sores in 15 patients. The design was a combination of the classic rotation and V-Y advancement flap patterns. When the wound was closed, the tension at the distal end of the rotation flap was relieved by flap advancement and the combined rotation-advancement action was supported laterally with V-Y closure. A wide skin pedicle was preserved at the inferomedial part of the flap. This pedicle augmented the blood supply to the flap skin and kept the surgical incision small, thus helping to reduce the risk of fecal contamination and associated wound-healing problems. This flap can also be converted to any design of fasciocutaneous or musculocutaneous V-Y advancement flap, should such a change be required. The largest defects that were closed with a unilateral rotation-advancement flap and bilateral rotation-advancement flaps were 12 and 18 cm in diameter, respectively. In 1.5 to 35 months of follow-up, none of the patients developed wound dehiscence or flap necrosis requiring repeated surgery. This technique is simple, can be performed quickly, has minimal associated morbidity, and yields a good outcome.     

Anterolateral thigh flap in the treatment of postburn flexion contractures of the knee

The use of the anterolateral thigh fasciocutaneous flap in the reconstruction of soft-tissue defects around the knee among burn patients is described. The anterolateral thigh fasciocutaneous flap was used for eight patients (all male; mean age, 45 years; age range, 32 to 60 years). Flexion contracture was observed for seven patients with unhealed wounds and one patient with a healed burn wound. The anterolateral thigh flap was used as a free flap for six patients and as a distally based island flap for two patients. The flaps ranged from 8 to 17 cm in width and from 12 to 30 cm in length. Seven flaps were based on a musculocutaneous perforator, and two of them were thinned before transfer to the defect. A true septocutaneous perforator was observed in only one case. The mean follow-up period was 12.5 months (range, 3 to 23 months). Only one flap exhibited distal superficial necrosis, which did not compromise the final result. All patients returned to ambulatory status in 15 to 22 days. Extensor splints were applied to prevent mobilization of the skin graft at the flap donor site for only 7 days. The anterolateral thigh flap has many advantages for the reconstruction of postburn flexion contracture of the knee, as follows: (1) very large thin flaps can be elevated, (2) the two-team approach is possible, (3) color and texture matches are good, (4) the donor-site scar can be easily hidden, and (5) the technique allows early mobilization and patients can return to normal daily activity in a short time. Free or distally based anterolateral thigh flaps are a good choice, both aesthetically and functionally, for the reconstruction of soft-tissue defects of the knee region.     

Management of soft-tissue problems in leg trauma in conjunction with application of the Ilizarov fixator assembly

Forty-five patients presenting with high-energy open grade III tibial diaphyseal fractures were treated with the Ilizarov technique. Of these patients, 28 required plastic surgical intervention for achieving wound closure. Most of the injuries were complicated by initial neglect and inadequate primary soft-tissue coverage resulting in osteitis, sequestration, and segmental diaphyseal tibial defects, often in combination with skin-envelope deficits of various types in and around the fracture perimeter. The unique soft-tissue problems encountered while using the Ilizarov fixator have not been focused on in previous reports on the management of segmental bone defects. Four basic local flap procedures: the transposition flap, rotation flap, adipofascial turnover flap, and Z-plasty are useful and versatile for managing most types and grades of soft-tissue defects associated with a segmental bone loss with the Ilizarov technique.     

The fasciocutaneous flap: a conservative approach to the exposed knee joint

The exposed knee joint poses a challenge to the reconstructive surgeon. The currently popular approach to the repair of exposed knee joints is use of muscle flaps. However, this leaves the patient with a deficit. We have therefore begun using the fasciocutaneous flap as an initial approach to this problem. In seven patients, aged 28 to 74 years, fasciocutaneous flaps have been the reconstructive procedure of choice for repair of exposed knee joints. One patient with a very large open wound required a concomitant medial gastrocnemius muscle flap. One minor wound separation occurred in a paraplegic patient with severe spasm. No other complications occurred. Follow-up ranged from 3 to 12 months, with good success in wound closure. An approach to small and intermediate wounds is presented in which the V-Y technique is used to obviate the need for skin grafting of the donor site.     

Fasciocutaneous island flap based on the medial plantar artery: clinical applications for leg, ankle, and forefoot

Soft-tissue deficits over the plantar forefoot, plantar heel, tendo calcaneus, and lower leg are often impossible to cover with a simple skin graft. The previously developed medial plantar fasciocutaneous island flap has been adapted to cover soft-tissue defects over these areas. This fasciocutaneous flap based on the medial plantar neurovascular bundle is capable of providing sensate and structurally similar local tissue. Application of this fasciocutaneous island flap is demonstrated in 12 clinical cases. Successful soft-tissue cover was achieved on the plantar calcaneus (four patients), tendo calcaneus (four patients), lower leg (two patients), and plantar forefoot (two patients). Follow-up ranged from 6 months to 5 years. All flaps were viable at follow-up. Protective sensation was present in 11 of 12 flaps evaluated at 6 months. In addition, all 11 patients were able to ambulate in normal footwear. The medial plantar island flap seems to be more durable than a skin graft, and the donor site on the non-weight-bearing instep is well tolerated. This study demonstrates that the medial plantar fasciocutaneous island flap should be considered as another valuable tool in reconstructive efforts directed at the plantar forefoot, plantar heel, posterior ankle, and lower leg.     

Osteocutaneous posterior interosseous flap for reconstruction of the metacarpal bone and soft-tissue defects in the hand

A vascularized bone segment of the ulna together with a posterior interosseous fasciocutaneous flap is harvested, including a cuff of the extensor pollicis longus muscle. The authors treated five male patients with metacarpal bone and soft-tissue defects of the hand using a distally based island osteocutaneous posterior interosseous flap. Their ages at the time of surgery ranged from 15 to 37 years (mean, 24 years). The bone defects were in the first metacarpal in three cases, the fourth metacarpal in one, and the fifth metacarpal in one. The length of the donated ulna ranged from 3 to 7 cm (mean, 5 cm). The follow-up period ranged from 5 to 92 months (mean, 39 months). All flaps survived completely. The posterior interosseous flap provides thin skin of good texture, together with vascularized bone, for a one-stage reconstruction of the metacarpal bone and soft-tissue defects in the hand.     

Our experience with Wisebands: a new skin and soft-tissue stretch device

Complex wounds that involve skin and soft-tissue defects that are unsuitable for primary closure by conventional suturing are common in the field of surgery. Among the many surgical options available to overcome these problems are various mechanical devices that have recently been proposed for delayed primary closure of such wounds. The authors present their experience with a new complex wound closure device, Wisebands, a device uniquely designed for skin and soft-tissue stretching. During the last 2 years, the authors have treated 20 patients with 22 skin and soft-tissue wounds for which primary closure was not feasible. The Wisebands devices were applied to the wounds, stretching the skin and underlying soft tissue, gradually closing the defects until the edges were sufficiently approximated for primary closure. Successful wound closure was achieved in 18 patients (90 percent). The Wisebands devices were removed in two patients (10 percent) because of major wound complications. In two other patients (10 percent), minor wound complications had occurred that did not necessitate removal of the device. At a mean follow-up of 1 year (range, 10 months to 2 years), stable scarring with no functional or significant aesthetic deficit was achieved. The authors conclude that the Wisebands device facilitates closure of complex skin and soft-tissue wounds, with low morbidity and complication rates, and can provide the surgeon with another important tool for closing complex wounds. Nevertheless, appropriate patient selection, intraoperative judgment, and close postoperative care are essential to ensure closure and avoid undue complications.     

Anterolateral thigh fasciocutaneous island flaps in perineoscrotal reconstruction

This study presents the authors' experience using the anterolateral thigh fasciocutaneous flap for complex perineal and scrotal reconstruction. Anterolateral thigh fasciocutaneous island flaps were performed in seven patients between January and June of 2000 (six male, one female; mean age, 52 years; age range, 9 to 72 years). Four of the seven patients had scrotal or perineal defects after multiple debridements for Fournier's gangrene. Two of these four had exposed testicles. Three flaps were used for recurrent ischial ulcers. A true septocutaneous perforator (type 1) running between the rectus femoris and the vastus lateralis muscles was found in only two patients. In four patients, the cutaneous perforators were found to be intramuscular, originating from the descending branch (type 2). In the other patient, the musculocutaneous perforator originated from the lateral circumflex femoris artery independently (type 3). In these cases, intramuscular dissections were performed to follow each perforator to its main trunk. Mean follow-up was 8 months (range, 5 to 10 months), and all flaps survived. Three patients developed minor wound dehiscence in the posterior aspect of the perineal wound because of fecal contamination and skin maceration. Both wounds healed secondarily. Scrotal reconstruction with the anterolateral thigh flap gave an excellent aesthetic result. The authors conclude that the anterolateral thigh flap is a reliable flap for perineoscrotal reconstruction.     

Immediate closure of traumatic upper arm and forearm injuries with the latissimus dorsi island myocutaneous pedicle flap

This paper reports the authors' experience with latissimus dorsi island pedicle flaps in the acute treatment of massive arm injuries. Seven patients with upper arm injuries and four patients with forearm injuries were treated with latissimus dorsi pedicle flaps. All cases involved massive soft-tissue loss and open fractures. Primary healing of wounds occurred without complications in 10 of 11 patients; the eleventh developed a wound infection. There were no instances of flap loss or vascular complications. This report compares and discusses surgical management options and details the importance of robust, immediate soft-tissue coverage for optimal functional recovery. Contrary to traditional thought, delay in definitive wound closure may be unnecessary when aggressive debridement is followed by acute flap closure.     

A reverse ulnar hypothenar flap for finger reconstruction

A reverse-flow island flap from the hypothenar eminence of the hand was applied in 11 patients to treat palmar skin defects, amputation injuries, or flexion contractures of the little finger. There were three female and eight male patients, and their ages at the time of surgery averaged 46 years. A 3 x 1.5 to 5 X 2 cm fasciocutaneous flap from the ulnar aspect of the hypothenar eminence, which was located over the abductor digiti minimi muscle, was designed and transferred in a retrograde fashion to cover the skin and soft-tissue defects of the little finger. The flap was based on the ulnar palmar digital artery of the little finger and in three patients was sensated by the dorsal branch of the ulnar nerve or by branches of the ulnar palmar digital nerve of the little finger. Follow-up periods averaged 42 months. The postoperative course was uneventful for all patients, and all of the flaps survived without complications. The donor site was closed primarily in all cases, and no patient complained of significant donor-site problems. Satisfactory sensory reinnervation was achieved in patients who underwent sensory flap transfer, as indicated by 5 mm of moving two-point discrimination. A reverse island flap from the hypothenar eminence is easily elevated, contains durable fasciocutaneous structures, and has a good color and texture match to the finger pulp. This flap is a good alternative for reconstruction of palmar skin and soft-tissue defects of the little finger.     

Triple coverage of ischial ulcers with adipofascial turnover and fasciocutaneous flaps

Despite a wide variety of flap options, ischial ulcers remain the most difficult pressure ulcers to treat. This article describes the authors' successful surgical procedure for coverage of ischial ulcers using adipofascial turnover flaps combined with a local fasciocutaneous flap. After debridement, the adipofascial flaps are harvested both cephalad and caudal to the defect. The flaps are then turned over to cover the exposed bone in a manner so as to overlap the two flaps. A local fasciocutaneous flap (Limberg flap) is applied to the raw surface of the turnover flaps. Twenty-two patients with ischial ulcers were treated using this surgical procedure. Overall, 86.4 percent of the flaps (19 of 22) healed primarily. Triple coverage with the combination of double adipofascial turnover flaps and a local fasciocutaneous flap allows for an easily performed and minimally invasive procedure, preservation of future flap options, and a soft-tissue supply sufficient for covering the prominence and bony prominence and filling dead space. This technique provides successful soft-tissue reconstruction for minor to moderate-size ischial pressure ulcers.     

Sacral adipofascial turn-over flap for the excisional defect of pilonidal sinus.

The aim of pilonidal sinus surgery includes complete resection of the lesion and filling of the resultant soft-tissue defect by some means; this has a major influence on whether a lesion will occur after surgical treatment. The creation of a sacral adipofascial turn-over flap for the excisional defect has been performed in seven cases of pilonidal sinus since November of 1992. During the postoperative follow-up period, which ranged from 10 months to 7 years 11 months (mean duration, 5 years 2 months), partial dehiscence of the wound as a result of fatlysis was observed and treated conservatively in one case; however, primary healing was obtained in the other cases. No recurrence was seen in any of the seven cases. This procedure is not indicated in patients in whom wide skin resection is required because of the excessive tension associated with skin closure in such cases. However, the method is convenient, less invasive, and reliable, and therefore considered to be useful in the treatment of pilonidal sinus.     

External oblique fasciocutaneous flap for elbow coverage

The external oblique fasciocutaneous pedicle flap can be used for reconstruction of soft-tissue defects of the elbow. This flap has been used in five patients, and results have been good. The technique is appropriate in patients with recurrent defects of the elbow in whom local tissue has been previously used and is no longer available. With the development of local fasciocutaneous units, this method may have limited application. However, because of the relationship of this flap to the elbow, the procedure can be done easily and rapidly with minimal immobilization. It is a clinical impression that blood supply to the skin is enhanced by elevation of its underlying fascia. Anatomic dissections have demonstrated that there is an axial-pattern blood supply to this flap arising from the lateral border of the external oblique muscle.     

Partial and complete reconstruction of Achilles tendon defects with the fasciocutaneous infragluteal free flap

Multiple attempts to repair the Achilles tendon can be associated with major soft-tissue defects of skin and tendon necessitating reconstruction with free flaps. In view of its specific anatomical characteristics, the fasciocutaneous infragluteal free flap is best suited for restoring sensibility and achieving nearly full function, including resumption of sporting activities, with minimum donor-site morbidity. The anatomy, dissection technique, and results of 100 percent successful skin and tendon defect reconstruction in seven patients are presented.     

The ulnar recurrent fasciocutaneous island flap: reverse medial arm flap

A new island fasciocutaneous flap raised on the inner medial surface of the upper arm has been used for reconstruction of soft-tissue defects of the elbow. The blood supply to this flap comes from the fasciocutaneous perforators of the ulnar recurrent vessels. This unique vascular arrangement allows for safe transference of the upper medial skin to the elbow region. This flap has been used to cover nine defects in eight patients, and results have been good. Except for one case of sensory disturbance, there were no complications or loss of overlying skin. It is a relatively quick and simple procedure involving only one stage that adequately corrects the skin defect around the elbow region and does not require prolonged splinting.     

Management of pressure sores in a specialty center. A reappraisal.

We report a study on the surgical management of 145 pressure sores in 115 patients treated in a spinal cord injury center. There is a definite trend toward better education of these patients, who do not develop their first pressure sores until years following the injury. When the patient comes in for an ulcer, he is usually healthy and the ulcer is small and clean. In such instances the ulcer can be excised and closed, preferably with a myocutaneous flap, and the patient can usually begin sitting by the 21st post-operative day. In the ideal setting he may be discharged to his home on a custom-fitted (for pressure) cushion within 4 to 5 weeks, without increasing the risk of recurrence. Prophylaxis for the future is, probably, the most essential part of the treatment.     

Have we found an ideal soft-tissue flap? An experience with 672 anterolateral thigh flaps

The free anterolateral thigh flap is becoming one of the most preferred options for soft-tissue reconstruction. Between June of 1996 and August of 2000, 672 anterolateral thigh flaps were used in 660 patients at Chang Gung Memorial Hospital. Four hundred eighty-four anterolateral thigh flaps were used for head and neck region recontruction in 475 patients, 58 flaps were used for upper extremity reconstruction in 58 patients, 121 flaps were used for lower extremity reconstruction in 119 patients, and nine flaps were used for trunk reconstruction in nine patients. Of the 672 flaps used in total, a majority (439) were musculocutaneous perforator flaps. Sixty-five were septocutaneous vessel flaps. Of these 504 flaps, 350 were fasciocutaneous and 154 were cutaneous flaps. Of the remaining 168 flaps, 95 were musculocutaneous flaps, 63 were chimeric flaps, and the remaining ten were composite musculocutaneous perforator flaps with the tensor fasciae latae. Total flap failure occurred in 12 patients (1.79 percent of the flaps) and partial failure occurred in 17 patients (2.53 percent of the flaps). Of the 12 flaps that failed completely, five were reconstructed with second anterolateral thigh flaps, four with pedicled flaps, one with a free radial forearm flap, one with skin grafting, and one with primary closure. Of the 17 flaps that failed partially, three were reconstructed with anterolateral thigh flaps, one with a free radial forearm flap, five with pedicled flaps, and eight with primary suture, skin grafting, and conservative methods.In this large series, a consistent anatomy of the main pedicle of the anterolateral thigh flap was observed. In cutaneous and fasciocutaneous flaps, the skin vessels (musculocutaneous perforators or septocutaneous vessels) were found and followed until they reached the main pedicle, regardless of the anatomic position. There were only six cases in this series in which no skin vessels were identified during the harvesting of cutaneous or fasciocutaneous anterolateral thigh flaps. In 87.1 percent of the cutaneous or fasciocutaneous flaps, the skin vessels were found to be musculocutaneous perforators; in 12.9 percent, they were found as septocutaneous vessels. The anterolateral thigh flap is a reliable flap that supplies a large area of skin. This flap can be harvested irrespective of whether the skin vessels are septocutaneous or musculocutaneous. It is a versatile soft-tissue flap in which thickness and volume can be adjusted for the extent of the defect, and it can replace most soft-tissue free flaps in most clinical situations.     

Clinical applications of the extended deep inferior epigastric flap

The extended deep inferior epigastric flap, described by Taylor et al. in 1983, consists of the lower portion of the rectus abdominis muscle and a superolateral fasciocutaneous extension based on the periumbilical perforators. We have used this flap four times to close large defects of the abdomen, groin, and thigh and twice as a free flap to close wounds of the head and leg. There were no ischemic complications, and there was uncomplicated wound healing in the recipient and in the donor wounds. We recommend this highly versatile and reliable flap as one to be considered early in planning the closure of large wounds.     

Management of secondary soft-tissue deficits following microsurgical head and neck reconstruction by means of another free flap

Secondary soft-tissue deficits may develop following a microsurgical reconstruction in the head and neck region because of inadequate planning or chronic effects of radiotherapy. Although most cases could be managed with alternative methods, free flaps might be necessary in difficult cases. Herein are described 11 cases of microsurgical head and neck reconstruction in which secondary soft-tissue deficits required transfer of another soft-tissue free flap. All patients had malignant tumors treated with surgical resection, and their defects were reconstructed with free flaps. Seven patients received either preoperative or postoperative adjunctive radiotherapy. These patients gradually developed signs and symptoms of soft-tissue deficiency in the reconstructed area, and a soft-tissue free flap transfer was required for treatment within an average of 21.5 months of their initial reconstruction. Five rectus abdominis, one rectus femoris, one latissimus dorsi, one tensor fasciae latae myocutaneous, one radial forearm, one medial arm, and one dorsalis pedis flap were used for this purpose. All flaps survived completely. The average follow-up time was 32 months. Significant improvement was achieved in all cases, and no further major surgical procedures were required. Secondary soft-tissue deficits that could not be predicted or prevented during the initial microsurgical reconstruction may be treated successfully by a subsequent free soft-tissue transfer in selected cases.
