title: In vitro biomechanical comparison of a 5-hole 4.5 mm locking compression plate and 5-hole 4.5 mm dynamic compression plate for equine proximal interphalangeal joint arthrodesis.
abstract: OBJECTIVE
  To compare the biomechanical properties of a 5-hole 4.5 mm narrow locking compression plate (LCP) and 5-hole 4.5 mm narrow dynamic compression plate (DCP) for equine proximal interphalangeal (PIP) joint arthrodesis.
  
  
  METHODS
  Experimental mechanical study.
  
  
  METHODS
  Cadaveric adult equine forelimbs (n = 6 pair).
  
  
  METHODS
  For each forelimb pair, 1 PIP joint was stabilized with LCP and the contralateral PIP joint with DCP. The 6 construct pairs were tested using a single-cycle, 3-point dorsopalmar bending system. PIP joints were evaluated with pre- and post-test radiography.
  
  
  RESULTS
  The LCP technique had significantly greater yield load, failure load, and stiffness under single-cycle, 3-point dorsopalmar bending to failure than the DCP technique. There was no significant difference between the 2 constructs for displacement at yield and failure point.
  
  
  CONCLUSIONS
  Biomechanically, the LCP technique provided significantly greater stability than the DCP technique under the test condition.
