title: A comparative study of bone shortening and bone loss with use of saw blades versus burr in hallux valgus surgery.
abstract: BACKGROUND
  The aim of this study was to assess bone loss and thickness of the cut with the use of a burr in percutaneous hallux valgus surgery.
  
  
  METHODS
  Twelve blocks of saw bone were used. Cuts of same depth were made in each block with two different saw blades and a burr. Each block was assessed for bone loss and thickness of the cut.
  
  
  RESULTS
  There was statistically significant (p<0.05) increased bone loss and thickness of the cuts with the use of a burr as compared to use of two different saw blades. The use of a burr resulted in threefold increased loss of bone material and fourfold increase in the thickness of the cut as compare to use of two different saw blades.
  
  
  CONCLUSIONS
  The metatarsal shortening is a risk factor in percutaneous hallux valgus surgery with the use of a burr.
