    Abstract:

    One-stage reconstruction of composite bone and soft-tissue defects in the forearm remains a tough challenge. Here, we present a case of reconstruction of complex tissue defect at forearm with a Chimeric Flap consisting of a sural neurocutaneous Flap and a fibular graft. A 61-year-old man suffered from a machine crush injury in his left forearm, resulting in a complex tissue defect including extensive dorsomedial soft-tissue, digit extensor muscles of 2-4 fingers, the muscle flexor carpi ulnaris, the ulna bone with 5.5 cm in length, segmental injuries of ulna nerve and vessels, and the radius fracture. The defects were reconstructed by a modified Chimeric Flap, in which the sural neurocutaneous Flap supplied by a peroneal perforator was used to repair the soft-tissue defect and the vascularized fibular graft was used to repair the ulna defect. The two components were supplied by the peroneal vessels. The ulnar nerve defect was bridged by a sural nerve graft. The venous congestion caused by thrombosis was observed at 24 hours postoperatively. After the venous anastomosis was reperformed, the Flap survived completely without other complications. Bone healing was achieved at the 7-month follow-up. The index and middle fingers reached nearly full range of motion, while the ranges of motion of metacarpophalangeal joint of the ring and little fingers were less than 60 degrees. The results showed that the modified Chimeric Flap may be an option for reconstruction of complex tissue defect in the forearm.

    Abstract:

    BACKGROUND The fibula Flap has been widely used for reconstruction of composite bone and soft-tissue defects. The skin paddle of the fibula Flap has played a critical role in providing a cutaneous component and good monitor for the bone component. In this report, the authors designed a perforator-based sural neurocutaneous Flap instead of a peroneal perforator Flap to enlarge a skin paddle for wound coverage. METHODS A novel Chimeric Flap was harvested based on the peroneal artery, and consisted of a sural neurocutaneous Flap and a fibular graft. The sural neurocutaneous Flap was elevated based on a single peroneal perforator and connected with the bone component by means of the peroneal artery. Two patients with complex bone and soft-tissue defects were treated by using this Chimeric Flap. In case 1, the radius defect was 8 cm in length and the soft-tissue defect measured 23 × 10 cm. In case 2, the distal radius was injured and the defect was 16 cm in length. The area of soft-tissue defect was 23 × 8 cm. In this case, the fibula head was used for wrist reconstruction. The soft-tissue defects in the two cases stretched across the palmar and dorsal surfaces of the forearm. RESULTS The lengths of the bone components were 10 and 16.5 cm, respectively, and the areas of the skin components were 24 × 12 cm and 25 × 10 cm, respectively. Both Chimeric Flaps survived completely without complications. The follow-up period was 42 months in case 1 and 16 months in case 2. Complete bone union was observed in both cases, and no remarkable degeneration of the fibular head occurred in case 2. The sural neurocutaneous Flap showed good texture match and contour. No serious donor-site complications occurred. The two patients were satisfied with their daily lives relative to the severity of their injuries. CONCLUSION The Chimeric Flap composed of a sural neurocutaneous Flap and a fibular graft by means of the peroneal artery is a good candidate for reconstruction of long bone defects associated with extensive soft-tissue defects in the extremities.

    Abstract:

    Large bone defects of extremities, especially those associated with soft tissue defects, represent difficult reconstructive problems. Chimeric Flap is a suitable option for reconstruction of complex bone and soft-tissue defects. In this report, we present the experience on use of the peroneal artery perforator Chimeric Flap for the reconstruction of complex bone and soft tissue defects in the extremities in 16 patients. The bone defects were located in the tibia in 8 patients, in both tibia and fibula in 1 patient, in the ulna in 2 patients, in both ulna and radius in 2 patients, and the metatarsal bone in 3 patients. The Flap was created with skin paddle and fibula bone segments based on independent perforators. The sizes of Flap ranged from 8 x 6 to 20 x 11 cm(2), and the length of fibular grafts ranged from 6 to 22 cm. All Flaps survived completely. Bone union was ultimately obtained in all cases at 5 to 11 months, while two cases suffered from stress fractures in 12 month and 18 month after operation, respectively, which eventually healed with external fixation treatment. The follow-up time ranged from 12 to 37 months. The definite bone hypertrophy was observed from X-ray at 18 months after operation. In conclusion, our results show that the peroneal artery perforator Chimeric Flap is a good option for reconstruction of complex bone and soft-tissue defects of extremities, particularly for those with three-dimensional defects and bone defects exceeding 6 cm in length.

    Co-Authors: Arzu Akcal, Tahsin Görgülü, Seckin Aydin Savas, Mehmet Af Akcal, Mehmet Can Ubur, Cumhur İbrahim Başsorgun
    Abstract:

    Abstract Background Chimeric osteomyocutaneous Flaps harvested from the subscapular artery system have been used in clinical practice. We describe the use of a novel circumflex scapular artery myocutaneous and/or vascularized scapular Chimeric Flap in a rat model and demonstrate optimal skin Flap dimensions. Materials and methods An 8 × 4-cm-rectangular skin Flap based on the circumflex scapular artery Flap was harvested, and the mean percentage of the surviving Flap area and the necrotic area were calculated to be 71% ± 17.9% and 29% ± 17.9%, respectively. Using Flap dimensions determined in the first part of our study, a 4 × 3-cm quadrangular portion of skin was marked over the scapula, and the serratus anterior muscle and a portion of the scapular bone were included in our Chimeric Flap model. Results The mean percentages of the surviving Flap and necrotic areas were 74% ± 6% and 25% ± 6%, respectively. Microangiographic and histologic studies revealed the vascularity of the skin island and identified the branches of the circumflex scapular artery that supplied the bone and muscle. Conclusions The circumflex scapular artery myocutaneous and/or vascularized partial scapular Chimeric Flap may be considered a branch-based Chimeric Flap and can be an acceptable Flap model due to its simplicity, reliability, and consistent vascularity. Furthermore, this Flap may have potential applications in studying Chimeric Flap hemodynamics.
