Background:
In Denmark, we have a national consensus to treat instable tro-
chanteric fractures with intramedullary nails (IMN), but the recommended
length of IMN is still to be clarified. Long IMN inserted to the corresponding
leading edge of patella has been suggested as the treatment of choice to reduce
the risk of fractures below the nail or in line with distal locking screws. However,
short IMN has other advantages such as shorter surgery time and lower eco-
nomical costs.
Purpose / Aim of Study:
The aim of this study was to compare the risk of
perioperative complications and reoperations following long and short IMN in
instable trochanteric fractures.
Materials and Methods:
In the Danish Fracture Database (DFDB) we identified
all patients with instable trochanteric fractures (AO type 31A (1-3)) treated
with long IMN or short IMN in the period 2011-2014 and included information
on perioperative complications. Data were linked to the Danish Interdisciplinary
Registry of Hip-Near Fractures (DIRH) to obtain information on reoperations
within 2 years after primary osteosynthesis
Findings / Results:
We included 1513 patients registered in DFDB with an
instable trochanteric fracture treated with long IMN (n = 451) or short IMN (n
= 1062). The prevalence of perioperative complications was 27 for short IMN
(2.5%) and 10 for long IMN (2.22%) (P>0.05). Data on reoperations registered
in DIRH are still pending.
Conclusions:
We found no difference in perioperative complications in patients
with instable trochanteric fractures treated with long IMN or short IMN. Data on
reoperations are still to be analyzed.
