Abstract
We analysed registry-based data on 14,915
patients treated for pertrochanteric fracture obtained from the Finnish Health
Care Register during the years 1999-2009. Data on the comorbidities,
residential status and deaths of the cohort were extracted from several Finnish
registries using patients' unique personal identification numbers. The use of
intramedullary implants increased substantially during the study period.
One-year mortality was slightly higher in the patients treated with
intramedullary implant (26.6% vs. 24.9%; P=0.011). In the first year after the
fracture, there were more new operations on hip and thigh in patients treated
with an intramedullary implant. Our
findings suggest that more expensive intramedullary implants do not lead to
better clinical outcomes than extramedullary implants for the treatment of pertrochanteric
fractures.
