Background The study aims to evaluate the clinical and functional outcomes of extra-articular distal humeral fractures (EADHFs) treated with a new anatomical plate compared with dual plates-plate fixation. Methods From January 2018 to June 2023, patients with EADHFs who underwent internal fixation with either the new anatomical plate or dual plates were recruited, and divided into two groups (new plate vs dual-plate group). Data were recorded and analyzed, including operation time, blood loss, and hospitalization costs. Clinical outcomes were assessed using the indictors of interests, such as healing time and the complications, including wound infection, vascular and nerve damage, and nonunion. The shoulder and elbow function was evaluated using the University of California Los Angeles (UCLA) shoulder score and Mayo Elbow Performance Score (MEPS) respectively. Results A total of 30 patients (21males, 9 females) with a mean age of 32.97 years were included, with 12 patients in the new plate group, and 18 patients in the dual-plate group. The mean postoperative follow-up duration was 14.50 ± 1.07 months (range, 13–17 months). Preoperative data showed no significant difference in age, sex, or cause of EADHF between the groups. Interestingly, patients treated with the new anatomical plate have shorter operation times, lower hospitalization costs, and faster healing process than those treated with dual plates. However, no significant differences were found between the two groups in clinical and functional outcomes assessed using the MEPS and UCLA shoulder score. Conclusion The new anatomical plate for EADHF treatment demonstrates advantages such as reduced surgical time, lower costs, and shorter healing duration, making it a viable alternative treatment option. However, larger-scale studies with longer follow-up periods are necessary to fully confirm its efficacy and long-term benefits.
