We aimed to evaluate functional and radiographic outcomes of patients with proximal humeral fractures treated with proximal anatomic locking plate and were classified according to the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) classification.


In this study we included 29 patients (13 females, 16 males) aged 16-82 years who were treated with proximal anatomic locking plate between February 2010 and July 2014. The mean follow up time was 17.76±8.31 months. The right shoulder was operated in 20 patients and the left shoulder in nine patients. Functional outcomes were assessed using the Constant-Murley and University of California at Los Angeles (UCLA) shoulder score and radiologic outcomes were assessed using anteroposterior radyograph.


At the final follow up, the mean Constant-Murley score was 75.48±18.69. The result was poor in 31.0% (n=9), moderate in 24.1% (n=7), 13.8% (n=4) good and excellent in 31.0% (n=9) of patients. The mean UCLA score was 30.10±5.73. The outcome was poor in 17.2% (n=5), good in 31.0% (n=9) and excellent in 51.7% (n=15) of patients. In 21 patients there were no complications, but complications occurred in eight. When we compared the patients per age groups (<65 and >65), there was no difference in collo-diaphyseal angle (p=0,097, p>0,05), but the Constant-Murley scores (p=0,001) and UCLA scores (p=0,01) were statistically higher in patients below 65 years of age than in those above 65 years.


Treathment with proximal anatomic locking plate is preferred since it supports early motion and leads to good functional results in partial proximal humeral fractures.
