Aim:To determine the functional outcome of shoulder Neer’s prosthesis for a four part fracture dislocation of shoulder. Methods: This prospective research was carried out in the Department of Orthopaedics. The research covered patients with comminuted four component fractures with humeral head as a distinct fragment, older individuals, osteoporotic fractures, lesser tuberosity and larger tuberosity as separate pieces. Results: Females made up 57.5 percent of the study population. The majority of patients (47.5 percent) were between the ages of 65-75, with those over 75 accounting for the remaining 25%. The mean age was 72.73±7.77 years, the mean forward flexion was 128.450±13.25 degrees, the mean internal rotation was 46.95o ±5.77 degrees, the mean external rotation was 25.9o ±2.11 degrees, the mean ASES score was 79.36±3.74, the mean VAS score was 1.5±0.48 degrees, and the mean Constant-Murley score was 82.1±4.61.
