Influence of stem length on sagittal alignment in total hip arthroplasty: a comparison between short and standard stems

Short stems offer enhanced intramedullary insertion freedom and improved anterior femoral offset, potentially leading to better alignment outcomes in THA. However, their increased freedom necessitates precise surgical planning, particularly in patients with wider medullary morphologies. These findings emphasize the importance of simulation-based planning in understanding the impact of stem length, while clinical studies are needed to validate these results.
