【摘要】 目的 探討切開復位肱骨近端內固定鎖定系統(proximal humeral internal locking system，PHILOS)治療老年肱骨近端骨折的療效。 方法 2008年5月-2009年5月，對22例60歲以上肱骨近端新鮮移位骨折按Neer分型，二部分2例，三部分16例，四部分4例；采用肩前方入路切開復位PHILOS治療。 結果 22例患者獲12～18個月隨訪，平均14.6個月，采用Constant-Murley評分，優8例，良10例，可3例，差1例，優良率81.4%。 結論 切開復位PHILOS治療老年肱骨近端骨折療效肯定。【Abstract】 Objective To discuss the clinical effect of open reduction and internal fixation with the proximal humeral internal locking system (PHILOS) plate in treating elder patients with proximal humeral fracture. Methods From May 2008 to May 2009, we classified 22 cases of fresh displaced proximal humeral fracture according to the Neer classification. All patients were older than 60 years. There were two cases of two-part fracture, 16 cases of three-part fracture and four cases of four-part fracture. The open reduction and internal fixation with PHILOS plate was performed with the anterior deltopectoral approach. Results The 22 patients were followed up for 12 to 18 months with a mean period of 14.6 months. According to Constant-Murley Shoulder Score measurement, eight cases were graded as excellent, 10 good, three fair, and one poor with a excellent and good rate of 81.4%. Conclusion The open reduction and internal fixation with Philos plate is effective in treating elder patients with proximal humeral fracture.
