Objectives: This study aims to evaluate the early- and mid-term shoulder and elbow functions and compare the union rates after the application of single plate and double plate for the treatment of humerus shaft nonunions.

Patients and methods: This retrospective study included 56 patients (36 males, 20 females; mean age 53.8±9.5; range, 28 to 68 years) treated with double plate (n=25) and single plate (n=31) osteosynthesis between October 2012 and January 2016. Surgical treatment of the nonunion was applied in the fourth month after the fracture at the earliest. Autograft taken from the iliac bone was applied during the surgery in all patients. Evaluation was performed using The University of California at Los Angeles (UCLA) Shoulder Score, Mayo Elbow Performance Score (MEPS), Visual Analog Scale (VAS), Constant Shoulder Score, and Disabilities of the Arm Shoulder and Hand (DASH) questionnaire.

Results: The mean postoperative follow-up time was 40.7±9.6 (range, 25 to 58) months. No statistically significant difference was determined in respect of time to union, follow-up time, DASH questionnaire score, UCLA Shoulder Score, VAS, MEPS and Constant Shoulder Score after union in the comparison of the two groups (p>0.05). In the examination of postoperative early (three months) recovery phase of shoulder and elbow functions, statistically significant superior scores were obtained in the double plate group for MEPS (double plate median=85 [min 75-max 90], single plate median=75 [min 70-max 85]) and Constant Shoulder Score (double plate median=89 [min 85-max 92], single plate median=81 [min 75-max 90]) (p<0.001).

Conclusion: There was no statistically significant difference in terms of time to union and union rates between single plate and double plate fixations for surgical treatment of humeral shaft nonunions. However, superior clinical results were obtained in the early recovery phase of shoulder and elbow functions with double plate fixation.
