This review aims to summarise the applications of finite element modelling used in labour mechanics and explore their clinical relevance in optimising labour management and intervention strategies. A systematic literature search was performed in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines across the PubMed, IEEE Xplore, Web of Science and Elsevier ScienceDirect databases. Selected 13 studies were evaluated based on the methodological quality assessment of single-subject finite element analysis (MQSSFE). The review highlights the widespread use of whole-body foetal finite element models in childbirth simulations. Key factors in childbirth biomechanics include uterine contraction intensity, abdominal muscle forces, pelvic floor function, foetal head flexion, tissue properties, and descent trajectory. Finite element modelling offers key insights but faces challenges in accuracy, personalised anatomy, and clinical application. Advances in computational biomechanics, imaging validation, and patient-specific simulations will improve childbirth understanding, risk assessment and labour management.
