Table 2 Outcomes for Intra-operative fracture

From: The suitability of an uncemented hydroxyapatite coated (HAC) hip hemiarthroplasty stem for intra-capsular femoral neck fractures in osteoporotic elderly patients: the Metaphyseal-Diaphyseal index, a solution to preventing intra-operative periprosthetic fracture

  1. OR = Odds Ratio. Chi2 P < 0.05* considered significant.
  2. This table confirms that revision, AO Cable fixation, Subsidence and 90 Day Mortality are all significant adverse outcomes for patients who sustain an intra-operative fracture.
