Flexible multibody system dynamics (MSD) is one of the hot spots and difficulties in modern
mechanics. It provides a powerful theoretical tool and technical support for dynamic …

Numerical models of the musculoskeletal system as investigative tools are an integral part of
biomechanical and clinical research. While finite element modeling is primarily suitable for …

Study Design: Retrospective cohort study. Objective: To determine if patients fused with multi-
rod constructs to the pelvis have a lower incidence of lumbosacral rod failure and …

The role of intra-abdominal pressure (IAP) in spinal load reduction has remained
controversial, partly because previous musculoskeletal models did not introduce the …

Abstract Development of a subject-specific computational musculoskeletal trunk model
(accounting for age, sex, body weight and body height), estimation of muscle forces and …

Although in vivo spinal loads have been previously measured, existing data are limited to
certain lumbar and thoracic levels. A detailed investigation of spinal loads would assist with …

Spinal intervertebral joints are complex structures allowing motion in multiple directions, and
many experimental studies have reported moment-rotation response. However …

Background Interbody fusion at the caudal levels of long constructs for adult spinal deformity
(ASD) surgery is used to promote fusion and secure a solid foundation for maintenance of …

Trabecular bone, a solid that has a heterogeneous porous structure, demonstrates nonlinear
stress–strain relationship, even within the small strain region, when subject to stresses. It …

Background The limitations of anterior cervical discectomy and fusion (ACDF) are related to
mechanical failure of the construct after recurring subsidence and migration. In the present …
