    Abstract:
    PURPOSE: To compare clinical and functional outcomes of two groups of patients undergoing reduction and nailing fixation for diaphyseal fractures of the tibia with (PEMF group) and without (control group) post-operative pulsed electromagnetic field (PEMF) application. METHODS: This is a retrospective study on 50 patients (mean age 43.3 years, 28 males and 22 females) with diaphyseal tibial fractures managed between 2017 and 2019. Twenty-five patients underwent reduction, nailing fixation, and PEMF application post-operatively (PEMF group) and 25 patients underwent nailing fixation. Radiographic imaging assessment was performed every month until fracture healing had been evident. Use of analgesics, fracture healing time, post-operative lower limb alignment, and post-operative complications were recorded. Patients were asked about return to preinjury activity. All patients were assessed at 3 months and at an average follow-up of 13 months. The VAS scale and Johner-Wruhs criteria were used for pain assessment and functional recovery, respectively. RESULTS: Comparing groups, VAS values were significantly lower in the PEMF group at three months and comparable at one year. The patients in the PEMF group took an average of 4.1 months to resume their preinjury activities, and control patients took an average of 5.3 months (P < 0.0001). According to the Johner-Wruhs score, the effective rate was 100% (25/25) in the PEMF group and 92% (23/25) in the control group (P = 0.14). CONCLUSIONS: PEMF application after intramedullary nailing is safe and reduces post-operative pain, use of analgesics, and the time of healing fracture. At one year, there is no difference in outcome measures, regardless of PEMF application.
