Coupling mechanism of spacesuit hip joint and thigh-femur for improved maneuverability of astronauts

open access: goldMaterials & Design, 2020
The spacesuit hip joint is a crucial component that helps with astronaut maneuvering activities such as walking and kneeling. The coupling mechanism of the hip joint with the thigh-femur, and its analytical solution, is less explored in this paper, a new

Femur originated genu varum in a patient with symptomatic ACL deficiency: a case report and review of literature

open access: yesBMC Musculoskeletal Disorders, 2021
Background Anterior cruciate ligament (ACL) injury may be associated with genu varum. There are a few indications in which the varus deformity can be corrected at the time of ACL reconstruction. However, as the genu varum originates mostly from the tibia

Bilateral Asymmetric Traumatic Dislocation of the Hip Joint [PDF]

open access: yesJournal of Trauma and Injury, 2018
Traumatic hip joint dislocations account for 2–5% of total joint dislocations. Bilateral asymmetric hip joint dislocation with anteriorly and posteriorly dislocation is an even more rare case because it was according to G.

A model-based approach to stabilizing crutch supported paraplegic standing by artifical hip joint stiffness [PDF]

open access: yes, 2003
The prerequisites for stable crutch supported standing were analyzed in this paper. For this purpose, a biomechanical model of crutch supported paraplegic stance was developed assuming the patient was standing with extended knees.
