Functional Outcome in Post-operative Patients of Proximal Humerus Fractures Treated Using Proximal Humerus Nail

Background: Proximal humerus fractures (PHFs) are a common fracture especially in the elderly age group.The incidence of proximal humerus fractures is expected to increase as elderly populations grow and osteoporosis prevalence increases.Nearly 85% of PHFs are minimally displaced and can be treated conservatively, but displaced fractures require anatomical reduction with internal fixation.Surgery aims to achieve early mobilisation and prompt return to pre-fracture activity level.Among all currently used methods of stabilising proximal humerus fractures, the best outcomes are achieved by angularly stable plate fixation and interlocking intramedullary nailing. Methods:The study included patients with PHFs who underwent surgery at the Mandya Institute of Medical Sciences from April 2023 to September 2024.Functional outcome was assessed using the Constant Murley Score (CMS) for the shoulder.Patients were followed up regularly for 6 months post-operatively.Results: In this 35-patient series, 57% were female, and the mean age was 53 years.Self-fall from standing height was the nature of trauma in 62.9% of the patients, and 62.85% of the patients presented with left-sided PHF.The majority (74.3%) of patients presented with a 2-part fracture according to Neer's classification.The functional outcomes indicated good recovery of shoulder function, with a final follow-up mean CMS of 74.94 points, comparable to those reported in the literature. Conclusion:The study confirms that proximal humerus nails are an effective treatment option for 2-and 3-part PHFs, yielding reliable outcomes comparable to locking plate fixation.
