Modular dual mobility (DM) prostheses in which a cobalt-chromium liner is inserted into a titanium acetabular shell ( This was a prospective study of patients between 18 and 65 years of age, with a body mass index (BMI) < 35 kg/m2 and University of California at Los Angeles (UCLA) activity score > 6, who received a modular cobalt-chromium acetabular liner, highly crosslinked polyethylene mobile bearing, and cementless titanium femoral stem for their primary THA. Patients with a history of renal disease and metal hardware elsewhere in the body were excluded. A total of 43 patients (30 male, 13 female; mean age 52.6 years (Aims
Patients and Methods
In order to address acetabular defects, porous metal revision acetabular components and augments have been developed, which require fixation to each other. The fixation technique that results in the smallest relative movement between the components, as well as its influence on the primary stability with the host bone, have not previously been determined. A total of 18 composite hemipelvises with a Paprosky IIB defect were implanted using a porous titanium 56 mm multihole acetabular component and 1 cm augment. Each acetabular component and augment was affixed to the bone using two screws, while the method of fixation between the acetabular component and augment varied for the three groups of six hemipelvises: group S, screw fixation only; group SC, screw plus cement fixation; group C, cement fixation only. The implanted hemipelvises were cyclically loaded to three different loading maxima (0.5 kN, 0.9 kN, and 1.8 kN).Objectives
Methods
The objective of this study was to explore dimensionality of
the Oxford Hip Score (OHS) and examine whether self-reported pain
and functioning can be distinguished in the form of subscales. This was a secondary data analysis of the UK NHS hospital episode
statistics/patient-reported outcome measures dataset containing
pre-operative OHS scores on 97 487 patients who were undergoing
hip replacement surgery. Objective
Methods
To investigate psychosocial and biomedical outcomes following
total hip replacement (THR) and to identify predictors of recovery
from THR. Patients with osteoarthritis (OA) on the waiting list for primary
THR in North West England were assessed pre-operatively and at six
and 12 months post-operatively to investigate psychosocial and biomedical
outcomes. Psychosocial outcomes were anxiety and depression, social
support and health-related quality of life (HRQoL). Biomedical outcomes
were pain, physical function and stiffness. The primary outcome
was the Short-Form 36 (SF-36) Health Survey Total Physical Function.
Potential predictors of outcome were age, sex, body mass index,
previous joint replacement, involvement in the decision for THR,
any comorbidities, any complications, type of medication, and pre-operative
ENRICHD Social Support Instrument score, Hospital Anxiety and Depression
scores and Western Ontario and McMaster Universities osteoarthritis index
score.Objectives
