A Comparison of the Intramedullary Pressures and Temperatures Generated during Reaming between the Standard Reaming System and a New Low Pressure Designed Reaming System
OTA Abstract 1998: The purpose of this study was to compare the new reamer system against the standard reaming system on the basis of IM pressures and temperatures generated.
Conclusion: The new low pressure IM reamer design appeared to significantly reduce pressures and reduce temperatures in cadaveric bones when tested against the standard reaming system.

Temperature Elevation in Cortical Bone during Intramedullary Reaming and the Effect of Intermittent IM Irrigation and Sharp Reamers
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 large amounts of cortical bone to be reamed, irrigation between reamer passages may provide an inexpensive, simple method to minimize the risk of thermal necrosis.

The Effect of Unreamed, Limited Reamed and Standard Reamed Intramedullary Nailing on Cortical Bone Porosity and New Bone Formation
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 fractures with a compromised circulation when stabilization with an intramedullary nail is being considered.
