Introduction: In developed countries, cementless THA is the hip replacement procedure of choice, taking over cemented THA. The uncemented THA necessitates the need of snugly fitting long femur stem which can later lead to thigh pain and proximal stress shielding seen in stems loading in diaphysis. Long conventional femur components carry risk of intra and early perioperative fracture risk upto 2.5% and incidence of thigh pain upto 11%. These issues can be avoided by preserving bone stock with the use of short metaphyseal femur stem that fix at metaphyseal cancellous bone. These proxima stems load femur metaphysis more physiologically and can be inserted in a minimally invasive way. Case report: Here we present a long term follow-up of 15 years of an operated case of left hip THA done using short proxima stem of DePuy in a 41 years old male suffer from left hip osteonecrosis. At 15 years, there was ballooning periacetabular osteolysis and loosening of acetabular cup. Conclusion: Short metaphyseal proxima stem of DePuy is a good alternative in uncemented THA, especially in young adults required hip replacement surgery due to debilitating hip disorder, giving similar survival rates when compared with conventional long femur stem. This provides advantage of being minimally invasive, less soft tissue damage, less stress shielding with more physiological load distribution and preserving bone stock. The revision replacement surgery that will be required eventually in future can be better managed due to preserved bone stock and soft tissue.
