Background:Proximal humerus fractures (PHFs) are fractures that occur in the upper part of the arm bone (humerus) near the shoulder. The present study was conducted to assess outcome of hemiarthroplasty for proximal humerus fractures. Materials & Methods:84 cases of proximal humerus fractures of both genderswere treated with hemiarthroplasty. Those who were treated within 4 weeks of fracture were put in group I and those who underwent HA for fracture non-union, malunion, or avascular necrosis were put in group II. Results: Group I had 22 males and 20 females and group II had 19 males and 23 females. Body mass index was 31.2kg/m2 and 30.6kg/m2, time from fracture to HA was 0.5weeks and 2.5weeks, anesthesia time was 310.4 minutes and 325.6 minutes and the length of stay was 5.6 days and 3.4 days in group I and II respectively. The difference was significant (P< 0.05).Neer fracture classification2 was seen in 9 in group I, 3 in 13and 4 in 20 in group I. Vertical tuberosity reduction was high in 23 and 21, anatomic in 10 and 11 and low in 9 and 10. Horizontal tuberosity reduction was seen in 34and 29, tuberosityresorption was none in 18 and 15, partial in 17 and 19 and complete in 7 and 8 in group I and II respectively. Tuberosity healed was seen in 23 and 24, glenoid erosion was nonein 20 and 19, mild in 16 and 14, moderate in 6 and 7 and severe in 0 and 2 respectively. Conclusion: Both acute HA for a PHF and delayed HA for fracture sequelae showed no statistically significant differences in outcomes.
