Abstract: Background and Objectives:
Fractures of proximal humerus are the second most common fracture of upper limb accounting 4% to 5% of all fractures. There are different modalities of surgical treatment like multiple k-wire fixation, proximal humeral nailing, locking plate osteosynthesis, TBW and Hemiarthroplasty of shoulder. The mode and type of fracture fixation depends on the fracture pattern, bone quality, age and activity of patient. The goal is to achieve near anatomical reduction and stable fixation so as to achieve early mobilization.
Method: A Prospective study of 30 cases of surgically managed fractures of Proximal Humerus Using Proximal Humerus (PHILOS) Locking Compression Plates undertaken at Department of Orthopaedics, J.J.M. Medical College, Davangere from 1st August 2019 to 31st July 2021 who follow Inclusion and Exclusion criteria. Post operative functional outcome was assessed by using Constant And Murley Scoring.
Result: The most common age group included in our study was between 50-60 years (50%) with mean age group being 47.66 years.20 patients had a fracture of right proximal humerus and10 had of the left side.Our study included 14(47)% patients with 2 part surgical neck fracture, 12(40%) with 3part surgical neck with greater tuberosity, 3(10%) with 3 part surgical neck with lesser tuberosity and 1(3%)patient with 2 Part greater tuberosity fracture. Functional results were 6(20%) patients had excellent result. 18(50%) patients had good, 4 (13.33%) patients had moderate and 2(6.66%) patients had poor result at 1 year follow up. The average Constant And Murley Score being 76.9.
Conclusion: PHILOS plate appears to be a new generation promising implant for the internal fixation of proximal humerus fractures. The design provides stable fixation even in osteoporotic bone and allows early mobilization of the joint. It is suitable for two-part, three-part fractures in young and in elderly patients providing that the correct surgical technique is used.
