“…He also developed a more realistic threedimensional FE model of lunate bone to investigate the specific Kienbock's disease [14]. Carrigan et al [15] developed a FE model to study the load transmission into the carpus under static load and concluded to the importance of the cartilage and the rotational degree of freedom of the carpal in the pressure distribution into the wrist. Tarnita et al [16] investigated mechanical parameters (stress and displacements) of a hand phalanx with the FE method under compression, torsion and bending loading, and a comparison with clinical observations of a number of real world hand trauma.…”

This paper investigates a biomechanical aspect of human hand during grasping, using the finiteelement method. A realistic three-dimensional finite-element (FE) model of a human hand is developed, including wrist bones, phalanges, soft tissues and skin, reconstructed from medical computed tomography (CT) scan images. Material laws of the literature have been implemented in the model, in order to be able to simulate a simple activity of grasping. In a human design context, this model allows an interesting biomechanical study, which simulates the grasping task in a biofidelic manner. This model is a first step in the modeling of the human hand that can lead to future studies dealing with the interaction of the hand with its environment for the improvement of safety requirements of future products development.

“…3,6,25,30 Ligament stiffness values for carpal ligaments were assigned from published experimental data, 8,24,31 or from previous computational models in the literature 5,7,16,35 ranging from 40 to 350 N/mm ( Table 1). All carpometacarpal and intermetacarpal ligaments represented in the model were assumed to have a stiffness of 100 N/mm.…”

“…This is especially true in attempts to model the complexity associated with the wrist joint. A limited number of computational models of the wrist have been created, but all have either restricted the study to two dimensions, 12,16,23,35 restricted the position of the wrist to a static posture, 5,12,18,23,35 or fused bones together to increase computational efficacy. 7 These simplifications decrease computation time and may be justified in various ways, but the native anatomical joint will not function in the same manner as the simplified joint.…”

“…The carpal bones of the wrist and their supporting ligaments are small in size and are routinely exposed to high loads in falls, often leading to carpal fracture and subsequent arthritis. 5 In addition to understanding the biomechanical consequences of injuries, the effects of surgical procedures could also have a major impact on quality of life, and being able to predict the function of a normal and/or pathological wrist joint complex is essential to understanding the biomechanical consequences of surgical reconstructive procedures, such as radioscapholunate (RSL) fusion and subsequent ostectomy.…”

“…Traditionally, biomechanical computational models of diarthrodial joints have been based either on finite element analysis (FEA) 5,14,21 or rigid body modeling (RBM). 7,8,12,13,[15][16][17][18][19][20]22,23,[34][35][36] FEA is a useful tool for calculating stresses and deformations but requires significant computational power.…”

In this study, a computational model of the wrist joint complex was developed and validated for investigating the biomechanical function of the joint in clinically representative scenarios. Joint behavior and kinematics were dictated only by osteoarticular contact, ligamentous constraints, and muscle loading. Three-dimensional articular surfaces of each bone were generated from CT images, while ligaments and muscles were modeled as linear springs and constant-magnitude force vectors, respectively. Commercially available rigid body dynamics software was to both build the model and simulate joint function. Range of motion model predictions were compared to a cadaveric study analyzing the effects of scaphoid distal pole excision and triquetral excision after radioscapholunate (RSL) fusion for validation. The computational model was able to accurately predict flexion, extension, radial deviation, and ulnar deviation motions in four states: normal (intact), RSL fusion, RSL fusion with the scaphoid distal pole excised, and RSL fusion with both the scaphoid distal pole and triquetrum excised. The model was also able to calculate other parameters of interest that are not easily obtainable experimentally, such as midcarpal forces. This model and modeling approach are anticipated to have value as a predictive clinical tool including effect of injuries or anatomical variations and initial outcome of surgical procedures for patient specific planning and custom implant design.

Most researchers have performed finite element (FE) analysis of the human forearm fracture by exploring the strength and load transmission of the bones. However, few studies concentrated a complete simulation of the whole forearm complex including ligaments. This paper aims to investigate the load transmission through the bones, contact stress at the joints and strain in the ligaments by using an elaborate FE model, further validating the fracture condition for human forearm. The interosseous ligament was separated into three regions based on the distance to the proximal and distal ends. The FE simulation results were slightly more or less than a previous experimental data in the literature, but generally provided a close approximation of the bone and ligament behaviors. Compared with the experiment results under different loading conditions, maximum contact stress at the proximal radio ulnar joint (PRUJ) and distal radio ulnar joint (DRUJ) of the simulations was higher with an average of 13.4%, and peak strain in the interosseous ligament (IOL) was lower with an average of 11.0%. Under 10 kg load, the maximum stress in the radius (2.25 MPa) was less than double the value in the ulna (1.43 MPa). Finally, the FE model has been validated with the onset and location of the Colles' fracture in the literature. This study will provide a great benefit in terms of surgical and medical applications related to forearm fracture that require an extensive knowledge of the behavior of the bones and ligaments under various loading conditions.
