Background:

Femoral fractures are common injuries requiring surgical intervention.
Intramedullary nailing is a standard treatment for femoral fractures.
AO femoral intramedullary locked nails offer a specific surgical option.

Purpose of the Study:

To evaluate the outcomes of AO femoral intramedullary locked nails in treating femoral fractures.
To assess complication rates and union times.
To determine the impact on knee joint mobility.

Main Methods:

Retrospective case series of 23 patients (24 nails).
Treatment performed at John Radcliffe Hospital, Oxford.
Follow-up duration longer than 4 months for acute traumatic fractures.

Main Results:

No major complications were reported in any of the 23 patients.
All 17 acute traumatic fractures achieved uncomplicated union.
Patients demonstrated an excellent range of knee movement post-treatment.

Conclusions:

AO femoral intramedullary locked nails are a safe and effective treatment for acute traumatic femoral fractures.
This method leads to successful bone union and preserves knee function.
The technique is associated with a low complication rate.
