Table 1 Age, time periods and survival

From: Safety aspects in surgical treatment of pathological fractures of the proximal femur – modular endoprosthetic replacement vs. intramedullary nailing

Age at operation (years) 61.9 (59.5 – 72.7) 73.8 (66.5 – 80.4) < 0.05
Time from initial diagnosis to operation (months) 54.5 (4.8 – 87.3) 24.0 (1.0 – 64.3) 0.43
Patient survival since operation (months) 4.5 (2.3 – 16.5) 2.0 (0.3 – 20.5) 0.58
Implant survival (months) 2.5 (1.0 – 7.5) 3.0 (0.3 – 11.0) 0.93
Implant durability (months) 4.5 (2.3 – 16.5) 2.0 (0.3 – 11.0) 0.31
Patient survival since initial diagnosis (months) 65.0 (10.8 – 112.0) 30.0 (1.5 – 87.5) 0.34
  1. Values are given as median values (interquartile range IQR). Implant survival reflects the time period from surgery until death, follow-up or revision for any reason. Implant durability refers to the time from surgery until death, follow-up or revision for structural implant failure only (i.e. nail breakage, periimplant/periprosthetic fracture, loosening, etc.).
