The pelvis, as a critical structure connecting the spine and lower limbs, not only supports the upper body but also plays a vital role in lower limb movement and force transmission. Its complex morphology and function have long been a focus of research. However, the significant individual variations in pelvic morphology present challenges in studying the relationship between shape and function. Statistical Shape Model (SSM), as an effective method for quantifying and describing morphological variations, has become a key tool in exploring the morphology-function relationship of the pelvis. This review summarizes the progress of SSM applications in biomechanical studies of pelvic morphology and function, highlighting its role in uncovering morphological features and their impact on biomechanics, and discusses future development directions. Through a comprehensive analysis of existing literature, we aim to provide valuable insights and references for clinicians, biomechanics researchers, and medical device designers.
