ABSTRACT
A 23-year-old female with Ewing's Sarcoma underwent tibial resection and skeletal reconstruction using proximal tibial allograft prosthetic reconstruction with distal femur endoprosthetic reconstruction and rotating hinge. Human acellular dermal matrix, (Alloderm, LifeCell, Branchburg, NJ, USA), was used to wrap the skeletal reconstruction. Soft tissue reconstruction was completed with a rotational gastrocnemius muscle flap and skin graft. Despite prolonged immobilization, the patient quickly regained full range of motion of her skeletal reconstruction. Synthetic mesh, tapes and tubes are used to perform capsule reconstruction of megaprosthesis. This paper describes the role of human acellular dermal matrix in capsule reconstruction around a megaprosthesis.
ABSTRACT
Perforator flaps are routinely used in upper- and lower-extremity reconstruction. Increased usage of these flaps as well as their intraoperative thinning has been described; however, there are limited reports of thinning in the postoperative period. From 2005 to 2010, thinning procedures were performed on 11 patients with 11 flaps. There were six males and five females in this series. Three flaps were deep inferior epigastric artery flaps, six flaps were anterolateral thigh flaps, and two were medial thigh flaps. After the initial microvascular reconstructive procedure, the patient underwent a second procedure where ultrasound-assisted lipoplasty, suction-assisted lipoplasty, flap advancement, and excision were performed. With aggressive, staged thinning procedures, there were no cases of partial or complete flap necrosis. Given the increasing number of perforator flaps being performed for upper- and lower-extremity reconstruction, a larger number of cutaneous flaps will need postoperative thinning. Ultrasound-assisted lipoplasty has been found to be a useful modality in revision of these flaps.

A 47-year-old female with a locally advanced urologic malignancy previously managed with resection, diversion, and postoperative radiation therapy presented for management of her recurrent cancer that had eroded through the soft tissues of the left inner thigh and vulva. On all staging studies the tumor involved the left common femoral artery, and vein, both above and below the inguinal ligament. The difficulty with such tumors is the availability of tissue to reconstruct the defect. The patient had a history of deep venous thrombosis in the femoral venous system. A local flap was the most logical type of reconstruction. The patient had a right lower quadrant ureterostomy with a large parastomal hernia which further limited the local flap options. An anterolateral thigh flap from the opposite thigh was used to reconstruct the soft tissue deficit in this patient. This resurfaced the defect and provided coverage for the vascular reconstruction.
