ABSTRACT
Objective To evaluate the clinical results of proximal humeral internal locking sys-tem(PHILOS)self-locking plates in treatment of proximal humeral fractures. Methods There were 35 patients including 19 males and 16 females(at mean age of 53.5 years,ranging from 29 to 92 years)with proximal humeral fractures treated with PHILOS plate.According to the Neer's classification sys-tem,there were two-part fractures in 19 patients,three-part fractures in 15 and four-part fractures in 1.Surgery was performed with PHILOS serf-locking plate via dehopectoral approach.All patients were fol-lowed up for mean 18.9 months(6-46 months)and evaluated by using Constant score and X-rays. Re-suits X-rays proved that all fractures got good reduction and complete healing during 8-12 weeks.The latest Constant scores was mean 89.5 points(82-94 points).There were no complications including plate loosing.humenral head necrosis or gleno-humeral ioint osteoarthritis. Conclusion PHILOS plate is a good choice for treatment of proximal humeral fractures because of its advantages including easy operation,stable fixation,good clinical results and few complications.
