A STUDY ON FUNCTIONAL OUTCOME OF PROXIMAL HUMERUS FRACTURES TREATED WITH PHILOS PLATING

Abstract
Background: Proximal humerus fractures are common and debilitating injuries. These fractures have a dual age distribution occurring either in young people following high energy trauma Usually high energy trauma associated with dislocation or in those older than 60 years with low-velocity injuries like simple fall, especially in elderly patients is due to osteoporosis and deforming forces of muscle attached. Wide range of treatment modalities ranging from conservative management to reverse shoulder arthroplasty. The non-operative method gives good results in stable and minimally displaced fractures. Displaced humeral neck fractures used to be managed conservatively in the past, but these were complicated by loss of reduction, malunion, non-union, stiffness and ultimately poor functional outcome. We took up this study to assess the efcacy and functional outcome of P.H.I.L.O.S. plating in proximal humerus. Our objectives are to study the fracture pattern with the Neer's criteria, to reconstruct the proximal humerus fracture anatomically with Philos plate, allow early shoulder mobilization and assessing the functional outcome using Constant Murley score. It is an Materials and methods: observational study of 30 patients (18 females and 12 males) with proximal humerus fractures that attended to the Department of Orthopaedics, Government General Hospital, Rangaraya medical college, Kakinada from December 2018 to December 2020. The mean follow-up Results: period was 12 months. Two patients lost follow-up. Of the remaining 28 patients, all fractures were united clinically and radiologically. At the nal follow-up the mean Constant-Murley score was 69.2 (range 50 -100). The results were excellent in 3, good in 12, fair in 10 patients, poor in 3 patients. During the follow-up 4 cases had varus mal-union, 5 had stiffness of the shoulder, 2 had supercial infection and1 had screw penetration. No cases of hardware failure, locking screw loosening or non-union were noted. T Conclusion: he divergent and convergent orientation of the locking screws of PHILOS plate provides stable biological xation with good radiological union. It minimises the soft tissue dissection and gives both axial and angular stability hence, reducing the risk of fracture displacement.
