OTA Abstract 1998
The purpose of this investigation was to compare the effects of unreamed nail insertion and limited or standard canal reaming, prior to insertion of an intramedullary nail, on cortical bone porosity and new bone formation.
Conclusions: The technique of limited reaming may be advantageous for the treatment of tibial...

Principles of Bone Healing from Neurosurg Focus 10(4), 2001 Iain H. Kalfas, M.D., F.A.C.S. Department of Neurosurgery, Section of Spinal Surgery, Cleveland Clinic Foundation, Cleveland, Ohio Abstract Our contemporary understanding of bone healing has evolved due to knowledge gleaned from a continuous interaction between basic laboratory investigations and clinical observations following procedures to augment...

Wheeless' Textbook of Orthopaedics Menu items include:- - stages of bone healing - radiographic determinants of healing - Age - negative influences on bone healing - Induction of Bone Healing

Bone can be considered as a biphasic composite material, mineral as one phase, and collagen and ground substance as the other The combined substances are stronger for their weight than either substance alone Cortical bone is stiffer than cancellous bone and more brittle, withstanding less strain before failure than cancellous bone ...

Orthoteers notes on the process of fracture healing

OTA paper 1998
To determine if intramedullary reaming causes temperature elevation in cortical bone of sufficient magnitude to cause thermal necrosis. Secondly to determine if intermittent IM irrigation or the use of sharp reamers will reduce this temperature elevation.
linical Application: Whenever possible, sharp reamers should be employed. In patients who require...
