Abstract

Objective:

To evaluate the outcomes of lengthening post-traumatic femoral segments using a recently available magnetic intramedullary (IM) lengthening system.

Design:

Retrospective cohort study.

Setting:

Urban level II Trauma Center.

Patients/Participants:

Patients treated for post-traumatic femoral shortening at our institution between 2012 and 2015. We identified 17 femurs lengthened (14 men and 3 women). The mean age was 30 years (range, 11–72 years).

Intervention:

Magnetic IM lengthening system.

Main Outcome Measurements:

Amount of lengthening achieved, consolidation index, and complications encountered.

Results:

The mean follow-up was 2.2 years (range, 1–3.7 years). Sixteen patients achieved the planned lengthening, a mean of 3.8 cm (range, 2.3–6.0 cm). Regenerate consolidation occurred at a mean of 119 days (range, 57–209 days). The mean consolidation index was 32 d/cm (range, 16–51 d/cm). Three patients (18%) experienced complications.

Conclusion:

IM lengthening nails are an improvement over external fixators for treatment of post-traumatic femoral shortening. Within certain limits, their use can be extended to problems of limb-length discrepancy with angular/rotational deformity.

Level of Evidence:

Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
