PurposeIntertrochanteric hip fractures are significant and costly injuries and there remains controversy within the orthopaedic literature over the best method of fixation. The Irish Hip Fracture Database (IHFD) was established in 2012 to drive improvements in clinical outcomes and the quality of hip fracture care. This paper will review the outcomes of dynamic hip screw (DHS) versus intra-medullary nailing (IMN) in the treatment of intertrochanteric hip fractures in Ireland. MethodsEligible cases for this study include patients >60 years of age with trochanteric hip fractures treated by DHS or IMN between January 2016 and December 2020. Outcomes recorded and compared include length of stay, inpatient mortality, mobilisation on post-operative day 1 (POD 1), and discharge destination. Results5668 hip fractures treated with DHS or IMN were identified. There was no significant difference between inpatient mortality, re-operation rate or length of stay between the two groups. Females and patients with a high ASA grade (IV and V) were more likely to receive IMN. Patients receiving DHS were more likely to be mobilised day 1 post-operatively and be discharged directly home. It was noted that the use of IMN increased from 42% of cases in 2016 to 70% in 2020. ConclusionIMN use for intertrochanteric fractures continues to increase. However, patients treated with DHS were more likely to mobilise early post-operatively and to go directly home. Notwithstanding the limitations of national registry data research, the dramatic rise in the use of IMN for these fractures appears unsupported by the evidence.
