Sarcomas arising from the chest wall account for less than 20% of all soft tissue sarcomas, and at this site, primitive tumors are the most frequent to occur. Leiomyosarcoma is a malignant smooth muscle tumor and the best outcomes are achieved with wide surgical excision. Although advancements have been made in treatment protocols, leiomyosarcoma remains one of the more difficult soft tissue sarcoma to treat. Currently, general local control is obtained with surgical treatment with wide negative margins. We describe the case of a 50-year-old man who underwent a chest wall resection involving a wide portion of the pectoralis major and minor muscle, the serratus and part of the second, third and fourth ribs of the left side...

Atraumatic instability of the hip has become an increasingly studied occurrence in recent years. There are several established surgical techniques that help restore stability of the native hip joint. In some cases, these procedures are not an option. As the phenomenon has become recognized more frequently, a greater number of revision surgeries are warranted in patients with ligamentous laxity. A durable solution for irreparable microinstability needs to be formulated to address this vulnerable patient demographic...

AlloDerm(®) (LifeCell Corp.; Brancburg, NJ) is an acellular dermal matrix (ADM) that serves as an immunologically inert scaffold in plastic surgery. In breast reconstruction, it is used as a filler for lumpectomy defects and can be used to create the inferolateral portion of the tissue expander pocket or implant pocket in postmastectomy patients. However, there are limited reports of the radiologic findings of AlloDerm(®) in patients who have undergone postmastectomy reconstruction. Familiarity with the imaging features of AlloDerm(®) is essential for correct diagnosis...

OBJECTIVE: Deficient bony ridges often complicate the implant treatment plan. Several treatment modalities are used to regenerate bone, including guided bone regeneration (GBR). The purpose of this study was to summarize the knowledge on different types of membranes available and currently used in GBR procedures in a staged approach or with simultaneous implant placement. The primary role of the membranes is to exclude epithelial and connective tissue cells from the wound area to be regenerated, and to create and maintain the space into which pluripotential and osteogenic cells are free to migrate...

BACKGROUND: Acellular dermal matrices (ADMs) are frequently used in reconstructive surgery and as scaffolds to treat chronic wounds. The 3-dimensional architecture and extracellular matrix provide structural and signaling cues for repair and remodeling. However, most ADMs are not uniformly porous, which can lead to heterogeneous host engraftment. In this study, we hypothesized that a novel human reticular ADM (HR-ADM; AlloPatch Pliable, Musculoskeletal Transplant Foundation, Edison, N...

BACKGROUND: Previous studies suggest that bridged mesh repair for abdominal wall reconstruction may result in worse outcomes than mesh-reinforced, primary fascial closure, particularly when acellular dermal matrix is used. We compared our outcomes of bridged versus reinforced repair using ADM in abdominal wall reconstruction procedures. METHODS: This retrospective study included 535 consecutive patients at our cancer center who underwent abdominal wall reconstruction either for an incisional hernia or for abdominal wall defects left after excision of malignancies involving the abdominal wall with underlay mesh...

BACKGROUND: The use of acellular dermal matrix has facilitated immediate prosthesis-based breast reconstruction. However, few studies directly compare surgical outcomes following acellular dermal matrix-based reconstruction with two of the most commonly available materials, AlloDerm and FlexHD. Those studies that are available often do not adequately control for the surgeon as a variable. The authors hypothesize that complication rates will not differ significantly between AlloDerm and FlexHD when practice and surgeon variables are properly controlled...

New generation of barrier membranes has been developed, which not only act as barriers but also as delivery devices to release specific growth factors. This study observed biological behaviors of bone morrow mesenchymal stem cells (BMMSCs) pretreated by bFGF or BMP-2 in vitro and evaluated differential bone regeneration process induced by bFGF and BMP-2 loaded acellular dermal matrix (ADM) membrane using critical-size rat calvarial defect model in vivo. The results showed that the proliferation capability of BMMSCs pretreated by bFGF was stronger than that by BMP-2, while there was temporally differential effect of bFGF and BMP-2 pretreatment on MSC osteogenic differentiation potentials...

BACKGROUND: Autologous breast reconstruction is associated with long-term patient satisfaction that is superior to implant-based approaches. Occasionally, however, patients who desire autologous reconstruction present with inadequate donor-site volume. A hybrid approach, combining free flap reconstruction with simultaneous implant placement, is a solution. We present our experience with the use of mesh for improved pocket control using this reconstructive modality. METHODS: A retrospective analysis of a prospectively maintained database of patients undergoing autologous breast reconstruction was performed...

BACKGROUND: Alloplastic materials are a mainstay in Asian rhinoplasty. However, the outline of alloplastic implants can become conspicuous over time in rhinoplasty patients, which is a significant cause for revision. In revision rhinoplasty, alloplastic materials can remain a viable and affordable option in Asian patients. The acellular dermal matrices (ADM) are often used to interface between the silicone material and the skin envelope. This study assesses histologic changes following implantation of ADM-covered silicone material in rats...
