INTRODUCTION We present our experience with limb salvage emphasising the use of vascularised bone grafts in combination with autoclaved tumour bone for limb salvage in osteosarcoma. MATERIALS AND METHODS Thirty-six cases with extremity osteosarcoma, all of which were managed at a single institution between 1980 and 1999, were reviewed at a mean follow-up of 9 years (range, 10 months to 200 mo...

in this investigation the effects of excess vitamin a administration during the early embryonic period were studied. intramuscular injection of a single dose of 15000,20000 or 25000 iu/kg vitamin a to pregnant balb/c strain mice on either day 7,8,9 or 10 of gestation (vaginal plug= day 0 of gestation) produced major malformations in the central nervous system (cns) including exencephaly, hydroc...

BACKGROUND AND AIM In order to create more uniformity in the prescription of upper limb prostheses by Dutch rehabilitation teams, the development and implementation of a Prosthesis Prescription Protocol of the upper limb (PPP-Arm) was initiated. The aim was to create a national digital protocol to structure, underpin, and evaluate the prescription of upper limb prostheses for clients with acqui...

Limb-preserving surgery using modular megaprostheses for the reconstruction of large skeletal defects is currently the preferred treatment for sarcomas. The authors report the postoperative outcomes after skeletal resection for lower extremity sarcomas and the use of the METS cemented modular implant system (Stanmore Implants, Hertfordshire, United Kingdom) for reconstruction. They retrospectiv...

The aim of this study was to clarify the role of Fgfr2 during later stages of embryonic development. Of two previously reported gene-targeting experiments, the more extensive Fgfr2 deletion was lethal shortly after implantation, because of trophoblast defects, whereas the less extensive one survived until midgestation with placental insufficiency and defective limb outgrowth [Xu, X., Weinstein,...

Warfare-related open fractures with large soft tissue defects create a significant reconstructive challenge. The objective of this article is to review current and evolving treatment strategies for soft tissue coverage of warfare-induced extremity wounds. A review of previously published literature and current data evaluating combat-injured personnel requiring extremity flap reconstruction perf...

OBJECTIVE We have previously shown that the tumor necrosis factor receptor 2 (TNFR2) protein is highly upregulated in vascular endothelium in response to ischemia, and a global deletion of TNFR2 in mice blunts ischemia-induced arteriogenesis and angiogenesis. However, the role of endothelial TNFR2 is not defined. In this study, we used endothelial cell (EC)-specific transgenesis of TNFR2 (TNFR2...

Upper limb reduction defi ciency (ULRD) is a rare condition that has been known ever since the 6 century B.C. This is a lifelong defi ciency which in an affl icted child can lead to practical limitations, social restrictions and physical problems. The overall aim of this research was to increase the knowledge about children with upper limb reduction defi ciencies from three perspectives: the de...
