This study specifically evaluates the effects of electromagnetic stimulation for diaphyseal femur fractures using a device developed by the investigators.

The hypothesis is that patients with femoral diaphysis treated with the electromagnetic stimulation have less non-union after six months than patients treated with a placebo device.

The inclusion criteria were: patients of any sex, age between 18 and 60 years, with a closed fracture in their femoral diaphysis or an open fracture secondary to a low-speed bullet; treated with open or closed reduction and intramedullary reamed blocked nail.

Patients were excluded if they had a pathological fracture, an open fracture from another etiology, or if they were treated after 10 days from the day of fracture.

64 patients were included.

Randomization took place six weeks after fracture day, allocating participants to either one of two groups: group A (electromagnetic stimulation) or group B (placebo).

Each group had a device exactly the same. Patients used the device during one hour every day for eight weeks.

Inclusion Criteria:

• Patients of any sex,
• age between 18 and 60 years, with a closed fracture in their femoral diaphysis or an open fracture secondary to a low-speed bullet;
• treated with open or closed reduction and intramedullary reamed blocked nail.

Exclusion Criteria:

• Patients were excluded if they had a pathological fracture,
• an open fracture from another etiology, or if they were treated after 10 days from the day of fracture.
