Table 3 Comparison of Uncemented and Cemented Groups, intra-operative fracture incidence and outcomes according to the Vancouver Classification

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

Study Groups Uncemented Cemented
   Intra-operative periprosthetic fracture
(n = 62, 15.2%) P < 0.001*
No fracture Intra-operative periprosthetic fracture
(n = 9, 5.9%)
No fracture

  1. Revision rate in Uncemented group with intra-operative fracture is 17.7% (P < 0.001)* with Odds ratio = 12.52 (95%CI 4.42-35.30).
  2. 90 Day mortality rate in Uncemented group with intra-operative fracture is 19.7% (P < 0.03) * with Odds ratio = 2.16 (95% CI 1.03-4.34)
  3. P < 0.05* significant findings confirm that adverse outcomes are strongly linked to the Uncemented group sustaining intra-operative fracture.
