Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to analyze the effect of PEMF in surgical reconstruction of 5th metatarsal non-union fractures.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators hypothesize:

1. That treatment of 5th metatarsal non-union fracture with PEMF will achieve earlier resolution and/or higher success compared to surgery alone of 5th metatarsal non-union fractures.
2. PEMF will stimulate increased expression of critical growth factors (i.e. BMP-2, BMP-4, BMP-7 as well as TGFb, IGF-1, FGF-2 and VEGF) at the non-union site to facilitate osseous healing of 5th metatarsal non-union fractures.
