Study on functional outcome of the proximal humeral internal locking system (PHILOS) for displaced proximal humeral fractures in adults

Background: The Incidence of trauma related skeletal injuries have been on the rise in recent years and proximal humerus fractures are one of the most common fractures occurring in the human body. Hence the present study was conducted to evaluate the clinical and functional outcome of the proximal humeral internal locking system (PHILOS) technology.The present study was undertaken to assess the functional and radiological outcome of the proximal humeral internal locking system (PHILOS) for displaced proximal humeral fractures in adults. Method:The present prospective observational study was conducted in adults with proximal humerus fractures admitted to department of orthopedics, GSL Medical College and General hospital Rajahmundry during study period from 1st October 2015 to 31st March 2017. The study was approved by the institute’s ethical committee. Patients were undergo Open reduction internal fixation with philos locking plating for the sustained fracture under general anaesthesia. Post-operative physiotherapy followed according to protocol, to evaluate the functional outcome. Result: The average age of patients was 44 years. Males were 16 and females were 09. Most common mechanism of injury observed was Road traffic accident in 72%. The Constant- Murley score was significantly improved (p=.000) over the successive follow-up period. 01 (04%) patient had excellent Constant-Murley scores, 11 (44%) patients had good scores, as like 11 (44%) had moderate scores and only 2 (08%) patients had a poor functional outcome. Conclusion:In conclusion, the proximal humeral locking plate seems to be an adequate device for the fixation of displaced two-part, three-part and four-part proximal humerus fractures. Due to stable fixation, early functional aftercare is possible and allows the patient to regain good shoulder function and resume normal activities much earlier.
