Objective:
To evaluate whether a single proximal interlocking bolt was sufficient during the treatment of extra-articular femur fractures with retrograde medullary nailing.
Design:
Retrospective comparative study.
Setting:
Academic Level 1 trauma center.
Patients:
The study included 136 patients with extra-articular femur fractures treated with retrograde medullary nailing who met inclusion and follow-up criteria.
Intervention:
The intervention included surgical treatment for a femur fracture with retrograde medullary nailing, with comparisons made between those treated with a single proximal interlocking (1 IL) bolt and those treated with 2 proximal interlocking bolts (2 IL).
Main Outcome Measurement:
The main outcome measurements were as follows: (1) rate of nonunion and (2) rate of catastrophic implant failure.
Results:
There was no difference in the rate of nonunion requiring surgical intervention between the 2 groups. There were no catastrophic failures in either group.
Conclusions:
A single proximal interlocking bolt may be sufficient when using retrograde nailing for the treatment of extra-articular femur fractures.
Level Of Evidence:
Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
