Modular hip implants are widely used in hip arthroplasty because of the advantages they can offer such as flexibility in material combinations and geometrical adjustments. The mechanical environment of the modular junction in the body is quite challenging due to the complex and varying off-axial mechanical loads of physical activities applied to a tapered interface of two contacting materials (head and neck) assembled by an impact force intraoperatively. Experimental analogies to the in-vivo condition of the taper junction are complex, expensive and time-consuming to implement; hence, computational simulations have been a preferred approach taken by researchers for studying the mechanics of these modular junctions that can help us understand their failure mechanisms and improve their design and longevity after implantation. This paper provides a clearer insight into the mechanics of the head-neck taper junction through a careful review on the finite element studies of the junction and their findings. The effects of various factors on the mechanical outputs namely: stresses, micromotions, and contact situations are reviewed and discussed. Also, the simulation methodology of the studies in the literature is compared. Research opportunities for future are scrutinised through tabulating data and information that have been carefully retrieved form the reported findings.

模块化的髋关节植入物由于其可以提供的优势（例如，材料组合的灵活性和几何形状的调整）而广泛用于髋关节置换术。由于在手术中通过撞击力施加到两种接触材料（头部和颈部）的锥形界面上施加的物理活动的复杂且变化的离轴机械负荷，因此体内模块化接合处的机械环境非常具有挑战性。体内实验类比锥形连接的条件是复杂，昂贵和费时的。因此，计算仿真已成为研究人员研究这些模块化结的力学的首选方法，可以帮助我们了解其失效机理并改善植入后的设计和寿命。本文通过对接头的有限元研究及其发现的仔细审查，提供了对头颈部锥形接头的力学的更清晰的了解。审查并讨论了各种因素对机械输出的影响，即：应力，微动和接触情况。此外，比较了文献中研究的模拟方法。
