Torsional stability of fixation methods in basicervical femoral neck fractures: a biomechanical study.
J Orthop Surg Res
June 2024
Department of Mechanical Engineering, Faculty of Engineering at Sriracha, Kasetsart University, Chonburi, Thailand.
Article Synopsis
- - The study investigates the structural strength of different fixation methods for basicervical femoral neck fractures, focusing on cephalomedullary nails (CMNs), dynamic hip screws (DHSs), and DHSs with an anti-rotation screw under torsion loads during early walking.
- - Using finite element analysis, it was found that the short CMN showed the highest stress and fragment displacement compared to the other methods, indicating potential instability.
- - The results suggest that DHS combined with an anti-rotation screw is the most effective option, offering lower risk of complications like screw cutout and better fixation stability for these types of fractures.
Impact of foot progression angle on spatiotemporal and plantar loading pattern in intoeing children during gait.
Sci Rep

School of Medical Imaging, Xuzhou Medical University, Xuzhou, China.
Intoeing in children is a common parental concern, but our understanding of the impact of foot progression angle (FPA) in these children leaves remains limited. This study examines the relationship between FPA and plantar loading pattern, as well as gait symmetry in children with intoeing. The sample included 30 children with intoeing caused by internal tibial torsion, uniformly divided into three groups: unilateral intoeing, bilateral mild intoeing, and bilateral mild-moderate intoeing.

BACKGROUND The aim of this study was to analyze the correlation and the accuracy of lower-extremity torsion deformities measured by physical examination, CT scan, and three-dimensional gait analysis in children with CP. MATERIAL AND METHODS The study group included 72 children with CP with lower-extremity torsion deformities. All subjects were assessed by: 1.

Children (Basel)

Department of Pediatric Orthopedics, Neuroorthopedics and Traumatology, University Children's Hospital Zurich, 8032 Zurich, Switzerland.
Background: Equinus deformity with or without concomitant drop foot is a common finding in children with unilateral spastic cerebral palsy and spastic hemiplegia of other causes. Hypothetically, these deformities may lead to pelvic retraction and hip internal rotation during gait. Orthoses are used to reduce pes equinus during gait and to restore hindfoot first contact.
