Abstract

Introduction: Intertrochanteric fractures are common in elderly population and pose a significant financial burden to the society. Anatomically contoured proximal femur locking compression plate (PFLCP) is the latest addition in the surgeons' armamentarium to deal with these fractures. It creates an angular stable construct, which will theoretically lessen the risk of failure by screw cut-out and varus collapse, the common mode of DHS failure. We compared DHS with PFLCP in AO type 31A1 and 31A2 intertrochanteric fractures.

Materials and methods: A randomized prospective study was carried out between June 2011 and June 2013. 26 cases each of DHS and PFLCP were included.

Results: Functional and radiological outcome was similar in both groups.

Conclusion: Both DHS and PFLCP are good choices for stable intertrochanteric fractures, and both lead to excellent functional outcomes, but non-union might be more common with PFLCP.

Keywords: Dynamic hip screw; intertrochanteric fractures; medialization; proximal femur locking compression plate; varus.
