Neuroma Implantation into Long Bones

Mesenchymal stem cell implantation in atrophic nonunion of the long bones

OBJECTIVES To explore the therapeutic potential of combining bone marrow-derived mesenchymal stem cells (BM-MSCs) and hydroxyapatite (HA) granules to treat nonunion of the long bone. METHODS Ten patients with an atrophic nonunion of a long bone fracture were selectively divided into two groups. Five subjects in the treatment group were treated with the combination of 15 million autologous BM-...

Treatment of painful peripheral neuroma by vein implantation.

Painful neuromas form on cutaneous nerves as a result of trauma, pressure, stretch or entrapment. Since the earliest descriptions of neuromas, proposed treatments have been met with poor results and controversy. The myriad of treatments described include: simple division of an affected nerve, implantation into muscle or bone, silicon sleeves and caps, repeated injection of steroids, end-to-side...

Make No Bones about It: Long Bones Scale Isometrically

Long bones are far from being simple cylinders, so how is the relative positioning of their various features maintained during growth? A new study shows that growth is isometric and that drift from the correct position is minimized. Read the Research Article.

How Did Dinosaur Bones Turn Into Fossils?

If fossilization was simply replacement of bone with stone, fossil and living bones wouldn't be as chemically similar as they are, and the intricate details found in fossilized dinosaur bones would not have survived [1]. Even more intriguing is the fact that some of the proteins in bone have survived the fossilization process, in dinosaurs and "older" fossils [2], a fact very consistent with a ...
