We compared the clinical and radiological outcomes of using a
polyetheretherketone cage with (TiPEEK) and without a titanium coating
(PEEK) for instrumented transforaminal lumbar interbody fusion (TLIF). We conducted a randomised clinical pilot trial of 40 patients
who were scheduled to undergo a TLIF procedure at one or two levels
between L2 and L5. The Oswestry disability index (ODI), EuroQoL-5D,
and back and leg pain were determined pre-operatively, and at three,
six, and 12 months post-operatively. Fusion rates were assessed
by thin slice CT at three months and by functional radiography at
12 months.Aims
Materials and Methods
Lifestyle risk factors are thought to increase the risk of infection
after acute orthopaedic surgery but the evidence is scarce. We aimed
to investigate whether smoking, obesity and alcohol overuse are
risk factors for the development of infections after surgery for
a fracture of the ankle. We retrospectively reviewed all patients who underwent internal
fixation of a fracture of the ankle between 2008 and 2013. The primary
outcome was the rate of deep infection and the secondary outcome
was any surgical site infection (SSI). Associations with the risk
factors and possible confounding variables were analysed univariably
and multivariably with backwards elimination.Aims
Patients and Methods
The aim of this study was to evaluate the long-term inducible
displacement of cemented tibial components ten years after total
knee arthroplasty (TKA). A total of 15 patients from a previously reported prospective
trial of fixation using radiostereometric analysis (RSA) were examined
at a mean of 11 years (10 to 11) postoperatively. Longitudinal supine
RSA examinations were acquired at one week, one year, and two years
postoperatively and at final follow-up. Weight-bearing RSA examinations
were also undertaken with the operated lower limb in neutral and
in maximum internal rotation positions. Maximum total point motion
(MTPM) was calculated for the longitudinal and inducible displacement examinations
(supine Aims
Patients and Methods
Our aim was to evaluate the radiographic characteristics of patients
undergoing total hip arthroplasty (THA) for the potential of posterior
bony impingement using CT simulations. Virtual CT data from 112 patients who underwent THA were analysed.
There were 40 men and 72 women. Their mean age was 59.1 years (41
to 76). Associations between radiographic characteristics and posterior
bony impingement and the range of external rotation of the hip were
evaluated. In addition, we investigated the effects of pelvic tilt
and the neck/shaft angle and femoral offset on posterior bony impingement.Aims
Patients and Methods
The aim of this study was to compare the rate of perioperative
complications following aseptic revision total hip arthroplasty
(THA) in patients aged ≥ 80 years with that in those aged <
80
years, and to identify risk factors for the incidence of serious
adverse events in those aged ≥ 80 years using a large validated
national database. Patients who underwent aseptic revision THA were identified in
the 2005 to 2015 National Surgical Quality Improvement Program (NSQIP)
database and stratified into two age groups: those aged <
80
years and those aged ≥ 80 years. Preoperative and procedural characteristics
were compared. Multivariate regression analysis was used to compare
the risk of postoperative complications and readmission. Risk factors
for the development of a serious adverse event in those aged ≥ 80
years were characterized.Aims

Methods
Our aim was to determine whether, based on the current literature,
bariatric surgery prior to total hip (THA) or total knee arthroplasty
(TKA) reduces the complication rates and improves the outcome following
arthroplasty in obese patients. A systematic literature search was undertaken of published and
unpublished databases on the 5 November 2015. All papers reporting
studies comparing obese patients who had undergone bariatric surgery
prior to arthroplasty, or not, were included. Each study was assessed
using the Downs and Black appraisal tool. A meta-analysis of risk ratios
(RR) and 95% confidence intervals (CI) was performed to determine
the incidence of complications including wound infection, deep vein
thrombosis (DVT), pulmonary embolism (PE), revision surgery and
mortality.Aims
Methods
Our aim was to examine the clinical and radiographic outcomes
in 257 consecutive Oxford unicompartmental knee arthroplasties (OUKAs)
(238 patients), five years post-operatively. A retrospective evaluation was undertaken of patients treated
between April 2008 and October 2010 in a regional centre by two
non-designing surgeons with no previous experience of UKAs. The
Oxford Knee Scores (OKSs) were recorded and fluoroscopically aligned
radiographs were assessed post-operatively at one and five years.Aims
Patients and Methods
Wound complications are reported in up to 10% hip and knee arthroplasties and there is a proven association between wound complications and deep prosthetic infections. In this randomised controlled trial (RCT) we explore the potential benefits of a portable, single use, incisional negative pressure wound therapy dressing (iNPWTd) on wound exudate, length of stay (LOS), wound complications, dressing changes and cost-effectiveness following total hip and knee arthroplasties. A total of 220 patients undergoing elective primary total hip and knee arthroplasties were recruited into in a non-blinded RCT. For the final analysis there were 102 patients in the study group and 107 in the control group.Objectives
Methods
A contact patch to rim (CPR) distance of <
10 mm has been
associated with edge-loading and excessive wear. However, not all
arthroplasties with a low CPR distance show problems with wear.
Therefore, CPR distance may not be the only variable affecting the
post-operative metal ion concentrations. We used multiple logistic regression to determine what variables
differed between the patients who had high and low cobalt (CoS)
and chromium (CrS) serum ion concentrations within a cohort of patients
with low (<
10 mm) CPR distances. A total of 56 patients treated
with unilateral hip resurfacing arthroplasty (HRA) had CoS and CrS
ion studies performed more than one year after surgery. The mean
age of the patients at the time of surgery was 51.7 years (29 to
70), with 38 women (68%) and 18 men (32%).Aims
Patients and Methods
Transtrochanteric rotational osteotomy (TRO) is performed for
young patients with non-traumatic osteonecrosis of the femoral head
(ONFH) to preserve the hip. We aimed to investigate the long-term
outcomes and the risk factors for failure 15 years after this procedure. This study included 95 patients (111 hips) with a mean age of
40 years (21 to 64) who underwent TRO for ONFH. The mean follow-up
was 18.2 years (3 to 26). Kaplan–Meier survivorship analyses were
performed with conversion to total hip arthroplasty (THA) and radiological
failure due to secondary collapse of the femoral head or osteoarthritic changes
as the endpoint. Multivariate analyses were performed to assess
risk factors for each outcome.Aims
Patients and Methods
The number of patients undergoing arthroscopic surgery of the
hip has increased significantly during the past decade. It has now
become an established technique for the treatment of many intra-
and extra-articular conditions affecting the hip. However, it has
a steep learning curve and is not without the risk of complications.
The purpose of this systematic review was to determine the prevalence
of complications during and following this procedure. Preferred Reporting Items for Systematic Reviews and Meta-Analyses
guidelines were used in designing this study. Two reviewers systematically
searched the literature for complications related to arthroscopy
of the hip. The research question and eligibility criteria were
established Aims

The aim of this study was to report a retrospective, consecutive
series of patients with adolescent idiopathic scoliosis (AIS) who
were treated with posterior minimally invasive surgery (MIS) with
a mean follow-up of two years ( We prospectively collected the data of 70 consecutive patients
with AIS treated with MIS using three incisions and a muscle-splitting
approach by a single surgeon between June 2013 and February 2016
and these were retrospectively reviewed. There were eight male and
62 female patients with a mean age of 15 years (Aims
