The effect of plate location on radial nerve palsy recovery time associated with humeral shaft fractures.

BACKGROUND

This study aims to investigate the influence of plate placement on nerve regeneration in humerus fractures accompanied by radial nerve injury.

METHODS

A retrospective analysis was conducted on a cohort of 94 patients with humerus fractures and concomitant radial nerve injury treated between January 2018 and November 2022. After applying exclusion criteria, 31 patients were included in the study. Clinical outcomes were assessed by comparing demographic data, surgical duration, radial nerve recovery time, the Mayo Elbow Performance Score (MEPS), Disabilities of the Arm Shoulder and Hand (DASH), and the Medical Research Council (MRC) scale.

RESULTS

Two distinct groups were established: lateral plating and anteromedial (AM) plating. These groups demonstrated comparability regarding age, gender, and body mass index (BMI). No statistically significant differences were observed between the groups concerning MEPS and MRC. The AM plating group notably exhibited shorter surgical durations, faster recovery times, and lower DASH scores.

CONCLUSION

According to the findings of this investigation, in cases of humerus fractures accompanied by radial nerve injury, AM plating may be preferable over lateral plating due to its association with reduced surgical durations and expedited nerve recovery.
