RESUMO
<p><b>OBJECTIVE</b>To investigate the effect of minimally invasive percutaneous plate osteosynthesis (MIPPO) for treatment of proximal humerus fractures with PHILOS plate.</p><p><b>METHODS</b>From January 2008 to July 2009, 22 cases of proximal humerus fractures were treated with MIPPO with PHILOS plate. According to Neer classification, 7 cases had two-part fractures, 12 had three-part fractures, and 3 had four-part fractures.</p><p><b>RESULTS</b>All the 22 cases were followed up ranging from 6 to 12 months with an average of 10 months. The functional results of the shoulder, according to Neer scores, were classified as excellent in 9 cases, good in 10 cases and fair in 3 cases, with an average score was 86.4%.</p><p><b>CONCLUSION</b>PHILOS using MIPPO shows good results for treating proximal humerus fractures.</p>
