Acetabular edge-loading was a cause of increased wear rates in metal-on-metal hip arthroplasties, ultimately contributing to their failure. Although such wear patterns have been regularly reported in retrieval analyses, this study aimed to determine their in vivo location and investigate their relationship with acetabular component positioning. 3D CT imaging was combined with a recently validated method of mapping bearing surface wear in retrieved hip implants. The asymmetrical stabilizing fins of Birmingham hip replacements (BHRs) allowed the co-registration of their acetabular wear maps and their computational models, segmented from CT scans. The in vivo location of edge-wear was measured within a standardized coordinate system, defined using the anterior pelvic plane.Aims
Methods
Ankylosing spondylitis (AS) is a progressive
multisystem chronic inflammatory disorder. The hallmark of this pathological
process is a progressive fusion of the zygapophyseal joints and
disc spaces of the axial skeleton, leading to a rigid kyphotic deformity
and positive sagittal balance. The ankylosed spine is unable to
accommodate normal mechanical forces, rendering it brittle and susceptible
to injury. Traumatic hyperextension injury of the cervical spine
leading to atlantoaxial
