[The value of radial shock wave therapy in the management of extended crural ulceration. Case report].

The authors present the history of a 36-year-old woman who had crural ulceration in the ventral side of the left lower limb due to venous circulatory failure for 5 years. In addition to the application of dressing adapted to the actual status of the wound, the authors applied an extracorporal shock wave therapy two times per week. After this treatment the size of the ulcer significantly decreased and it became suitable for mesh-graft cover.

[The use of Integra dermal regeneration matrix in the surgical treatment of a recurrent, extensive, malignant skin lesion in the temporal region].

Authors report on the use of Integra dermal regeneration template after excision of an extended, recurrent skin tumor in the temporal region. The area covered with Integra was 180 cm2. Skin grafting to cover Integra was performed on the 28th day.

[The role of Integra dermal regeneration matrix in skin replacement on the upper extremity].

Authors report the application of Integra dermal regeneration matrix in 10 patients in 12 indications (ages 25-74 years, 6 female and 4 male patients). The smallest reconstructed area was 6 cm2, the largest was 500 cm2. Skin coverage was needed on the lower arm in two patients, on the lower arm and the hand in two patients and on the hand in six patients.

[Use of Integra in a case of extensive upper extremity avulsion].

Authors performed successful skin replacement with Integra, a dermal regeneration template, on a patient with circumferential avulsion injury including the elbow region and the dorsum of the hand. The take rate of Integra was 97%, followed by a 98% take rate of the split thickness mesh graft used for final wound coverage. Treatment modality provided excellent aesthetic and functional results, underlining the role of Integra in cases of extensive traumatic skin and soft tissue deficit, such as the treatment of avulsion injury.

[Mandibular reconstruction with free osteocutaneous fibula flap using the occipital artery as recipient vessel].

Authors performed reconstructive surgery for extensive skin and mandibular bone defect following gunshot injury to the left side of the face. The soft tissue and bone defect was reconstructed with the free osteocutaneous fibula flap harvested from the left lower leg, as suitable local reconstructive flap was not available. The bony continuity was reestablished with a 7 cm long fibula segment.

[Posterior circumflex humeral artery perforator flap (PCHAP-flap) in axillary scar release].

Scar contracture after burn injury is frequent in the axillary region. If conservative treatment of scars limiting the range of motion of the shoulder joint fails, surgical correction is needed. The authors performed an early reconstruction in a case with unstable scar formation and limited range of motion after burn injury to the axillary region, using the posterior circumflex humeral artery perforator flap.

[The use of Integra "artificial skin, dermal regeneration template" and the reverse radial forearm fasciocutaneous flap in the primary reconstruction of a septic hand injury].

Unlabelled: Reconstruction was performed on the back of a hand following a poorly managed septic hand injury leading to skin and extensor apparatus necrosis using a reverse radial forearm fasciocutaneous flap and a bilayer artificial skin substitute.

Case Demonstration: Authors report on the first Hungarian case using Integra dermal regeneration template. Integra was placed on the back of the hand on an area left uncovered by the reverse radial forearm fasciocutaneous flap as well as on the flap harvest area.

[Skin replacement with biological and biosynthetic materials following burn injury].

Autotransplantation is currently regarded as the optimal skin replacement method, sufficient donor site, however, is often not available in extensively burned patients. Intensive research and development of skin replacement products is conducted worldwide in order to decrease the size of the required donor site. Short- and long-term wound coverage is made possible by temporary synthetic and non-synthetic skin substitutes.
