Reconstruction of soft tissue defects including the Achilles tendon with free neurovascular tensor fascia lata flap and fascia lata. Case report

The combined loss of the Achilles tendon and the overlying soft tissue in the young ambulant patient with expectations of a normal life is a challenge. These patients need not only skin coverage but also dynamic, functioning repair. Two cases of major defects after tumour resection are presented. In each case the tendon was reconstructed using the remaining gastrocnemius aponeurosis reinforced with fascia lata. This was covered by a free tensor fascia lata (TFL) flap. In one of the cases the flap was transferred as a neurovascular free flap.     

Reconstruction of the Achilles tendon and overlying soft tissue by free composite anterolateral thigh flap with vascularized fascia lata

Segmental loss of the Achilles tendon with overlying soft tissue and skin defect remains a complex reconstructive challenge. Successful reconstruction combines tendon repair with coverage of the defect by soft tissue flaps, creating an entity that meets up to three predetermined goals: (1) approaching preinjury functionality, (2) resisting shearing forces, and (3) achieving an esthetic result. From June 2009 to June 2011, our center submitted six patients to a one-stage procedure correcting the Achilles tendon using a composite free anterolateral thigh (ALT) flap with vascularized fascia lata. The flap sizes ranged from 5 to 8 cm in width and 16 to 20 cm in length and all flaps included vascularized fascia lata which was rolled to serve as an Achilles tendon. After reconstruction our patients showed good functional results, these patients could walk, climb stairs, and tiptoe again without support. Moreover, normal footwear could be worn. A free composite ALT flap with vascularized fascia lata is a reliable option for coverage of Achilles tendon and overlying soft tissue defects, even in elderly patients.     

One-stage reconstruction of soft tissue and Achilles tendon defects using a composite free anterolateral thigh flap with vascularized fascia lata: clinical experience and functional assessment

The combined loss of the Achilles tendon with overlying soft tissue is a reconstructive challenge. To achieve acceptable rehabilitation, such patients need skin coverage including functional repair of the Achilles tendon. This article presents four such patients who were treated successfully by means of an anterolateral thigh (ALT) composite flap with vascularized fascia lata. The size of the ALT flaps ranged from 10 to 16 cm in length and 6 to 9 cm in width. All flaps included vascularized fascia lata, which was rolled to serve as vascularized tendon graft (range 8 x 6 cm to 10 x 8 cm) for reconstruction of the Achilles tendon defect. Flap success rate was 100%. All patients could walk and climb stairs without support; however, mild difficulty when running was reported. Functional outcome of the recipient ankle and donor thigh morbidity were investigated by using a kinetic dynamometer comparing reconstructed sides with the healthy contralateral limbs. This assessment was performed in two patients at 2 years postoperatively. In the reconstructed ankles, isokinetic concentric measurements of dorsiflexion and plantar flexion showed a deficit of 30% and 40%, respectively. Functional evaluation of quadriceps femoris muscle contraction forces after free ALT composite flap harvest showed a 10% to 25% deficit. However, there were no difficulties in daily ambulating. In summary, the free composite ALT flap with vascularized fascia lata provides an alternative option for Achilles tendon reconstruction in complex defects.     

Reconstruction of abdominal wall by whole thigh flap.

Closure of extensive abdominal wall defects can be a very challenging task as there are no known large local or free vascularized flaps available that could cover the entire abdomen. Tensor fascia latae (TFL) has been widely used for abdominal wall reconstruction [Hill HL, Nahai F, Vasocnez LO. The tensor fascia lata myocutaneous free flap. Plast Reconstr Surg 1978;61:517-22]. However, the dimensions of the standard TFL flap limit its use in cases of large full thickness abdominal wall defects. Therefore, we have used an ingenious technique of raising the entire thigh skin as a fasciocutaneous flap (whole thigh flap) based on the concept of fusion of angiosomal territories, to reconstruct such a defect following excision of a large abdominal wall tumour.     

Definitive foot drop deformity repair with tensor fascia latae myocutaneous flap

Tensor fascia latae (TFL) myocutaneous flap, utilized as a novel approach for the successful functional repair of the foot drop deformity is presented in this case report. A 21‐year‐old male patient was subjected to a close‐range high‐velocity gunshot injury and sustained comminuted Gustillo‐type IIIB open fracture of his left tibia. A composite skin and soft tissue defect including tibialis anterior and extansor hallucis longus tendons was determined. The injury was managed in two stages. In the first stage, the immediate reconstruction of the open tibia fracture was provided by using a reverse flow sural flap and external fixation of the fracture. The functional restoration was achieved by vascular fascia latae in the second stage, 6 months after the initial skin, soft tissue, and bone defect repair. The functional recovery was successful, and the foot drop gait was almost totally ameliorated. Reconstruction with TFL flap should be retained in the armamentarium for the functional repair of the foot drop deformity, caused by composite skin and soft tissue defects of the pretibial region. © 2012 Wiley Periodicals, Inc.

Free tensor fasciae latae flap for abdominal wall reconstruction: overview and new innovation

Extensive abdominal wall defects may result from tumor extirpation, traumatic injury, or soft tissue infections. Extensive traumatic injuries can often disrupt the soft tissue content of the abdomen as well as the bony support provided by the pelvis. Reconstruction of the lower abdomen should aim to recreate dynamic stability. Five patients with extensive lower abdominal wall disruption following traumatic injuries or infection were treated using a novel flap for functional reconstruction. We devised a free neurotized osteomyocutaneous tensor fasciae latae (TFL) flap that would restore bony continuity by providing a vascularized bone graft and simultaneously maintain the integrity of the attachment of the tensor fascia latae muscle to the iliac crest, reestablishing musculofascial continuity. A branch of the superior gluteal nerve was harvested with this composite flap and coapted to an intercostal nerve for reinnervation, thereby creating a dynamic muscle in these patients. All patients underwent successful free tissue reconstruction with 100% flap survival. The lower abdominal wall and bony integrity of the pelvis were successfully reconstructed. Reinnervation has shown clinical signs of maintained dynamic stability. The innervated TFL osteomyocutaneous flap is an ideal option for lower abdominal reconstruction in patients with complex abdominoperineal defects with loss of bony integrity.     

Die Deckung von Weichteildefekten und instabilen Narben über der Achillessehne durch freie mikrochirurgische Lappenplastiken

INTRODUCTION: Coverage of the exposed Achilles tendon requires thin, supple tissue to provide adequate range of motion and a satisfying aesthetic result for the distal lower extremity. Various local flaps and free flaps have been described for reconstruction of small and large defects. Small defects can be closed with local tissue, whereas free flap coverage may be necessary for coverage of large defects. METHODS: From July 1993 to September 1998 14 patients between the age of 15 and 74 years (mean 47 years; 3 female, 11 male) underwent free flap coverage for the exposed Achilles tendon due to primary trauma, chronic wounds or tumors. The mean duration of follow-up was 33.3 months. The defect size ranged from 8 x 8 to 25 x 28 cm. RESULTS: Six parascapular flaps (three with a vascularized scapular fascial extension), four radial forearm flaps and four latissimus dorsi flaps (one combined with free serratus fascia) were used for soft tissue coverage over the Achilles tendon. Thirteen flaps survived. In one case a parascapular flap had to be removed due to venous thrombosis and a free latissimus dorsi flap was used as secondary salvage procedure. The donor site morbidity was acceptable for most patients after flap harvesting in the subscapular region and also satisfactory in the forearm region. Average active range of motion in the upper ankle joint was 15-0-40 degrees for extension/flexion. All patients were satisfied with the functional and aesthetic result. CONCLUSION: Soft tissue coverage over the exposed Achilles tendon requires an optimal solution for each patient to achieve an aesthetically pleasing result and acceptable function. Microvascular free flaps can be used to reconstruct medium and large defects and to provide gliding tissue for the Achilles tendon. The complication rate of microvascular flaps is comparable with that of local flaps.     

Reconstruction of combined defects of the Achilles tendon and the overlying soft tissue with a fascia lata graft and a free fasciocutaneous lateral arm flap

A new approach to reconstruction of the Achilles tendon and overlying soft tissue is presented. A fascia lata graft is used to reconstruct the tendon and is enwrapped by the fascia that is included in a fasciocutaneous lateral arm flap. Five patients were treated with this technique; three of them after surgical Achilles tendon repair, rerupture, and consecutive infection, one after a full-thickness burn with loss of the tendon and one with a history of ochronosis and necrosis of the whole tendon and overlying soft tissue. There were no anastomotic complications and all flaps healed primarily. Functional evaluation with the Cybex II dynamometer was done at least 49 months after reconstruction. A good functional and cosmetic result was obtained in all patients and donor site morbidity was acceptable. These results are well within the results of other surgical treatment options reported in the literature.     

The free musculocutaneous tensor fascia lata flap as a backup procedure in tumor surgery

The musculocutaneous tensor fascia lata (TFL) flap provides a small muscle belly and a strong fascial layer in combination with abundant skin coverage (15 x 40 cm), which makes the flap an attractive unit for composite free tissue transfer. The free TFL flap was used in nine cases of recurrent cancer of the chest wall (N = 7) and the abdominal wall (N = 2). The mean size of the full-thickness defects after tumor excision measured 12 x 25 cm. The operating time ranged from 4 to 8 hours (mean operating time, 5.5 hours). The operation was performed with two teams, and no repositioning of the patient was necessary during the operation. By raising the TFL flap, no additional area of the trunk was involved. The authors did not experience a prolonged ventilation time in their group of multimorbid patients. The donor site was closed directly (4 of 9 patients) or split skin grafted (5 of 9 patients). There was no functional deficit. In one patient the venous anastomosis had to be revised. There were no further complications, and no flaps were lost. The hospital stay was short (21 days on average), the outcome successful, and primary healing was obtained. The free TFL flap proved to be a reliable flap that is easy technically to harvest. Thus the free TFL flap is a valuable backup procedure in tumor surgery.     

Anatomic analysis of the vascular network and vascular pedicle of the tensor fascia lata flap (angiographic and cadaver study)

Knowing the vascular network and properties of the vascular pedicle is of crucial importance for elevation of the tensor fascia lata (TFL) transpositional or free flap; therefore, the origin of the lateral circumflex femoral artery (LCFA), its diameter at the site of origin, the length of the vascular pedicle, the number of lateral branches, the number of terminal branches and the anastomosis of the LCFA ascending branch are of utmost importance for successful elevation and clinical application of this flap. The study was conducted on clinical (100 angiographic images of the femoral artery) and autopsy (48 preparations) material. The first part of the study comprised analysis of the angiographic images that were used to obtain the information on LCFA. The diameter of LCFA at its origin was measured to be 0.44 cm, while it was 0.33 cm at the origin of ascending branch. The mean value of the diameter at the bifurcation of the terminal branches of ascending branch (inside tensor fascia lata muscle) was 0.24 cm. It has been established that the vascular pedicle of the tensor fascia lata flap (ascending branch of LCFA) is anastomosed with the superior gluteal artery in all cases. Measurement of the tensor fascia lata muscle revealed an average length of 15.91 cm, width of 3.55 cm and thickness of 1.98 cm. Injection of colour-ink into the ascending branch LCFA that enters directly into the TFL muscle was used to measure the extent of the TFL flap vascularization and on the average, the TFL flap was 20.32 cm long and 16.57 cm wide while the surface was 17.52 cm³.     

Use of the medial upper arm fascia to bridge biceps tendon defects

Options to bridge biceps tendon defects which have been described in the literature include fascia lata, semitendinosus tendon, flexor carpi radialis, Achilles tendon-calcaneus composite allografts and Achilles tendon allografts. In this study, the author reports the use of the upper arm fascia. This option is considered most suitable for patients who require simultaneous pedicled latissimus dorsi flap coverage of concurrent traumatic complex anterior elbow defects.     

Reconstruction of the Achilles tendon and overlying soft tissue using antero-lateral thigh free flap.

Reconstruction of combined loss of the Achilles tendon and overlying soft tissue was performed using an antero-lateral thigh free flap in three patients. The cutaneous portion is used to cover the open wound, and a piece of fascia lata is utilised to replace the missing segment of the Achilles tendon. The skin defect ranged from 5 x 2.5 to 7 x 5 cm, and the tendon loss measured from 3.5 to 5.5 cm in length. All of the patients showed satisfactory functional results with a follow-up period from 3 to 9 months. The advantages of the procedure are that: it is a single-staged operation; it promotes rapid healing of the tendo Achilles since the tendon substitute is well vascularised; it is adaptable to a wide range of defect sizes and shapes; it can be performed in the supine position without the need for postural change; and it can restore good contour and causes minimal morbidity at the donor site.     

Reconstruction of large abdominal wall defects

Reconstruction of a large abdominal defect is a technically demanding procedure. A single flap is sometimes insufficient for cover. Compound procedures play an important role in solving this problem. The case of a 35-year-old man with a large abdominal hernia as a result of a traumatic defect on the right abdomen, previously covered by a skin graft, is presented. The reconstructive method was initially expansion of posterior and upper parts of the defect and also of the tensor fascia lata in situ and then deepithelization of the previous skin graft over the intestinal serosa. The defect was covered by Prolene mesh, the upper and dorsal expanded skin was approximated, and an expanded tensor fascia lata flap was transposed to complete the cover. During follow-up examinations, there were no complications such as infection or recurrence of the hernia. Received: 29 January 1999 / Accepted: 14 June 1999     

Total abdominal wall reconstruction with two tensor fascia lata myocutaneous flaps

A case of total abdominal wall reconstruction in a 22-year-old man is presented. He had an omphalocele which was covered initially with skin grafts, thus creating a huge abdominal hernia. Two tensor fascia lata flaps, each measuring 14×36 cm, were used to reconstruct the abdominal wall following delay. This method, when-ever available, is in our opinion the best and most reliable way to reconstruct the abdominal wall. Myocutaneous flaps now have extended use in plastic and reconstructive surgery [1, 3, 5, 6, 8, 10]. The tensor fascia lata (TFL) myocutaneous flap is unique in its fascial extension and large overlying skin territory which makes it ideal for abdominal wall repairs.     

Tensor fascia latae perforator flap: An alternative reconstructive choice for anterolateral thigh flap when no sizable skin perforator is available

Introduction:

The anterolateral thigh flap (ALT) is a versatile flap and very useful for the reconstruction of different anatomical districts. The main disadvantage of this flap is the anatomical variability in number and location of perforators. In general, absence of perforators is extremely rare. In literature, it is reported to be from 0.89% to 5.4%. If no sizable perforators are found, an alternative reconstructive strategy must be considered. Tensor fascia lata (TFL) perforator flap can be a good alternative in these cases: Perforator vessels are always present, the anatomy is more constant and it is possible to harvest it through the same surgical access. The skin island of the flap can be very large and can be thinned removing a large part of the muscle allowing its use for almost the same indications of the ALT flap.

Materials and Methods:

We report 11 cases of reconstruction firstly planned with the ALT flap, then converted into TFL perforator flap.

Results and Conclusion:

The result was always satisfactory in terms of the donor site morbidity and reconstructive outcome.KEY WORDS: Anterolateral thigh flap, perforator flap, tensor fascia lata, tensor fascia lata     

Reconstruction of Achilles tendon using vascularised fascia lata with free lateral thigh flap

A case of Achilles tendon reconstruction using free vascularised fascia lata joined to a lateral thigh flap is reported. This is a simple one-stage reconstruction and a sufficiently strong tendon can be obtained.     

Free grafts of gliding tissue – principles and practice

The gliding tissue that covers the distal fascia of the tensor fascia lata (TFL) is sufficiently vascularized to be used as a free graft. It consists of loose areolar tissue and fat. Because of its gliding properties it is used to provide the functions of a bursa, e.g., elbow, knee, and of mucosal sheets, e.g., ankle. This gliding tissue provides an ideal cover for nerves which must move in mobile areas.     

Functional total and subtotal heel reconstruction with free composite osteofasciocutaneous groin flaps of the deep circumflex iliac vessels

Functional and esthetic reconstruction of the bony and tendinous structures with a stable, sensate soft tissue integument after complex posttraumatic defects of the heel is demanding. Cases are rare in the literature and hardly comparable due to their heterogeneity. The reconstructive approach has to consider both patient profile and the reconstructive tree, with free microvascular flaps playing a primary role. The goals are the reconstruction of both osteotendinous structures and slender soft tissue lining for proper shoe fitting for ambulation and mechanical and thermal protection. The flap should be sensate in weightbearing areas to optimize gait and to prevent long-term complications by ulcers. The osteofasciocutaneous deep inferior circumflex artery (DCIA) flap is especially suitable for complex heel defects with subtotal or total loss of the calcaneal bone as all components (iliac bone, groin skin, and fascia lata) can have a wide range of size and shape. We operated on 2 cases with this variable composite flap. One patient had a complete heel defect by war shrapnel. The complete calcaneus, soft heel, and Achilles tendon were reconstructed. The second patient had an empty os calcis after a comminuted fracture and a lateral crush-induced soft tissue defect. In both patients, a stable wound closure, osseous integration, and weightbearing ambulation could be achieved.     

Midurethral autologous fascial sling surgery with reconstruction of the lower abdominal wall using the tensor fascia lata muscle flap for post‐hemipelvectomy stress urinary incontinence

Hemipelvectomy is surgery for pelvic bone neoplasms. In the case of pubic bone osteosarcoma, the distal end of the rectus abdominis muscle is severed from the pubic and ischium bones, and the pelvic floor muscles are resected en bloc with the bone, which leads to stress urinary incontinence. Cancer control is prioritized over complications, and stress urinary incontinence is generally disregarded. A 25‐year‐old woman presented with stress urinary incontinence. She had undergone a hemipelvectomy for left pubic bone osteosarcoma, and stress urinary incontinence appeared and persisted since the surgery. We carried out a reconstruction of the tissue deficit of the rectus abdominis using the tensor fascia lata muscle flap simultaneously with a midurethral autologous fascial sling anchoring to the tensor fascia lata flap. Stress incontinence was successfully improved without morbidity. This is the first reported case of midurethral suspension with reconstruction of the lower abdominal wall with the tensor fascia lata flap for post‐hemipelvectomy stress urinary incontinence.
