Patients with femoral neck fractures (FNFs) treated with total hip arthroplasty (THA) have an almost ten-fold increased risk of dislocation compared to patients undergoing elective THA. The surgical approach influences the risk of dislocation. To date, the influence of differing head sizes and dual-mobility components (DMCs) on the risk of dislocation has not been well studied. In an observational cohort study on 8,031 FNF patients with THA between January 2005 and December 2014, Swedish Arthroplasty Register data were linked with the National Patient Register, recording the total dislocation rates at one year and revision rates at three years after surgery. The cumulative incidence of events was estimated using the Kaplan-Meier method. Cox multivariable regression models were fitted to calculate adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for the risk of dislocation, revision, or mortality, stratified by surgical approach.Aims
Methods
The aim of this study was to compare the rate of mortality and
causes of death in Korean patients who undergo surgery for a fracture
of the hip, up to 11 years after the injury, with a control group
from the general population. National cohort data from Korean Health Insurance Review and
Assessment Service – National Sample Cohort were used. A ratio of
1:4 matched patients with a fracture who underwent surgery (3383,
fracture group) between 2003 and 2012, and controls (13 532) were
included. The matches were processed for age, gender, income, and
region of residence. We also undertook analyses of subgroups according
to age and gender. The mean follow-up was 4.45 years (1 to 11).Aims
Materials and Methods
In order to prevent dislocation of the hip after total hip arthroplasty
(THA), patients have to adhere to precautions in the early post-operative
period. The hypothesis of this study was that a protocol with minimal
precautions after primary THA using the posterolateral approach
would not increase the short-term (less than three months) risk
of dislocation. We prospectively monitored a group of unselected patients undergoing
primary THA managed with standard precautions (n = 109, median age
68.9 years; interquartile range (IQR) 61.2 to 77.3) and a group
who were managed with fewer precautions (n = 108, median age 67.2
years; IQR 59.8 to 73.2). There were no significant differences between
the groups in relation to predisposing risk factors. The diameter
of the femoral head ranged from 28 mm to 36 mm; meticulous soft-tissue
repair was undertaken in all patients. The medical records were
reviewed and all patients were contacted three months post-operatively
to confirm whether they had experienced a dislocation. Aims
Patients and Methods
Revision total hip replacement (THR) for young
patients is challenging because of technical complexity and the potential
need for subsequent further revisions. We have assessed the survivorship,
functional outcome and complications of this procedure in patients
aged <
50 years through a large longitudinal series with consistent treatment
algorithms. Of 132 consecutive patients (181 hips) who underwent
revision THR, 102 patients (151 hips) with a mean age of 43 years
(22 to 50) were reviewed at a mean follow-up of 11 years (2 to 26)
post-operatively. We attempted to restore bone stock with allograft
where indicated. Using further revision for any reason as an end point,
the survival of the acetabular component was 71% ( This overall perspective on the mid- to long-term results is
valuable when advising young patients on the prospects of revision
surgery at the time of primary replacement. Cite this article:
