Fractures of the hip are common, often occurring
in frail elderly patients, but also in younger fit healthy patients following
trauma. They have a significant associated mortality and major social
and financial implications to patients and health care providers.
Many guidelines are available for the management of these patients,
mostly recommending early surgery for the best outcomes. As a result,
healthcare authorities now put pressure on surgical teams to ‘fast
track’ patients with a fracture of the hip, often misquoting the
available literature, which in itself can be confusing and even
conflicting. This paper has been written following an extensive review of
the available literature. An attempt is made to clarify what is
meant by early surgery (expeditious Cite this article:
We aimed to quantify the relative contributions of the medial
femoral circumflex artery (MFCA) and lateral femoral circumflex
artery (LFCA) to the arterial supply of the head and neck of the
femur. We acquired ten cadaveric pelvises. In each of these, one hip
was randomly assigned as experimental and the other as a matched
control. The MFCA and LFCA were cannulated bilaterally. The hips
were designated LFCA-experimental or MFCA-experimental and underwent
quantitative MRI using a 2 mm slice thickness before and after injection
of MRI-contrast diluted 3:1 with saline (15 ml Gd-DTPA) into either
the LFCA or MFCA. The contralateral control hips had 15 ml of contrast
solution injected into the root of each artery. Next, the MFCA and
LFCA were injected with a mixture of polyurethane and barium sulfate
(33%) and their extra-and intra-arterial course identified by CT
imaging and dissection.Aims
Materials and Methods
Our aim was to report survivorship data and lessons learned with
the Corail/Pinnacle cementless total hip arthroplasty (THA) system. Between August 2005 and March 2015, a total of 4802 primary cementless
Corail/Pinnacle THAs were performed in 4309 patients. In March 2016,
we reviewed these hips from a prospectively maintained database.Aims
Patients and Methods
One goal of total hip arthroplasty is to restore normal hip anatomy.
The aim of this study was to compare displacement of the centre
of rotation (COR) using a standard reaming technique with a technique
in which the acetabulum was reamed immediately peripherally and
referenced off the rim. In the first cohort the acetabulum was reamed to the floor followed
by sequentially larger reamers. In the second cohort the acetabulum
was only reamed peripherally, starting with a reamer the same size
as the native femoral head. Anteroposterior pelvic radiographs were
analysed for acetabular floor depth and vertical and horizontal position
of the COR.Aims
Patients and Methods
The increased The proximal penetration of the femoral head five years post-operatively
was measured for 15 patients using radiostereometric analysis (RSA).Aims

Femoral impaction bone grafting was first developed in 1987 using
morselised cancellous bone graft impacted into the femoral canal
in combination with a cemented, tapered, polished stem. We describe
the evolution of this technique and instrumentation since that time. Between 1987 and 2005, 705 revision total hip arthroplasties
(56 bilateral) were performed with femoral impaction grafting using
a cemented femoral stem. All surviving patients were prospectively
followed for a mean of 14.7 years (9.8 to 28.3) with no loss to
follow-up. By the time of the final review, 404 patients had died.Aims
Patients and Methods
The role of high tibial osteotomy (HTO) is being questioned by
the use of unicompartmental knee arthroplasty (UKA) in the treatment
of medial compartment femorotibial osteoarthritis. Our aim was to
compare the outcomes of revision HTO or UKA to a total knee arthroplasty
(TKA) using computer-assisted surgery in matched groups of patients. We conducted a retrospective study to compare the clinical and
radiological outcome of patients who underwent revision of a HTO
to a TKA (group 1) with those who underwent revision of a medial
UKA to a TKA (group 2). All revision procedures were performed using
computer-assisted surgery. We extracted these groups of patients
from our database. They were matched by age, gender, body mass index,
follow-up and pre-operative functional score. The outcomes included
the Knee Society Scores (KSS), radiological outcomes and the rate
of further revision.Aims
Patients and Methods
Risk of revision following total knee arthroplasty (TKA) is higher
in patients under 55 years, but little data are reported regarding
non-revision outcomes. This study aims to identify predictors of
dissatisfaction in these patients. We prospectively assessed 177 TKAs (157 consecutive patients,
99 women, mean age 50 years; 17 to 54) from 2008 to 2013. Age, gender,
implant, indication, body mass index (BMI), social deprivation,
range of movement, Kellgren-Lawrence (KL) grade of osteoarthritis
(OA) and prior knee surgery were recorded. Pre- and post-operative
Oxford Knee Score (OKS) as well as Short Form-12 physical (PCS)
and mental component scores were obtained. Post-operative range
of movement, complications and satisfaction were measured at one
year.Aims
Patients and Methods
Patients with an acute Achilles tendon rupture (ATR) take a long
time to heal, have a high incidence of deep vein thrombosis (DVT)
and widely variable functional outcomes. This variation in outcome
may be explained by a lack of knowledge of adverse factors, and
a subsequent shortage of appropriate interventions. A total of 111 patients (95 men, 16 women; mean age 40.3, standard
deviation 8.4) with an acute total ATR were prospectively assessed.
At one year post-operatively a uniform outcome score, Achilles Combined
Outcome Score (ACOS), was obtained by combining three validated,
independent, outcome measures: Achilles tendon Total Rupture Score,
heel-rise height test, and limb symmetry heel-rise height. Predictors
of ACOS included treatment; gender; age; smoking; body mass index;
time to surgery; physical activity level pre- and post-injury; symptoms; quality
of life and incidence of DVT. Aims
Patients and Methods
The aims of this study were to evaluate the clinical and radiological
outcomes of the Universal-2 total wrist arthroplasty (TWA) in patients
with rheumatoid arthritis. This was a retrospective review of all 95 Universal-2 TWAs which
were performed in our institution between 2003 to 2012 in patients
with rheumatoid arthritis. A total of six patients were lost to
follow-up and two died of unrelated causes. A total of ten patients
had bilateral procedures. Accordingly, 75 patients (85 TWAs) were
included in the study. There were 59 women and 16 men with a mean
age of 59 years (26 to 86). The mean follow-up was 53 months (24
to 120). Clinical assessment involved recording pain on a visual
analogue score, range of movement, grip strength, the Quick Disabilities
of the Arm, Shoulder and Hand (DASH) and Wrightington wrist scores.
Any adverse effects were documented with particular emphasis on
residual pain, limitation of movement, infection, dislocation and
the need for revision surgery. Radiographic assessment was performed pre-operatively and at
three, six and 12 months post-operatively, and annually thereafter.
Arthroplasties were assessed for distal row intercarpal fusion and
loosening. Radiolucent zones around the components were documented
according to a system developed at our institution.Aims

A trial-based comparison of the use of resources, costs and quality
of life outcomes of arthroscopic and open surgical management for
rotator cuff tears in the United Kingdom NHS was performed using
data from the United Kingdom Rotator Cuff Study (UKUFF) randomised
controlled trial. Using data from 273 patients, healthcare-related use of resources,
costs and quality-adjusted life years (QALYs) were estimated at
12 months and 24 months after surgery on an intention-to-treat basis
with adjustment for covariates. Uncertainty about the incremental
cost-effectiveness ratio for arthroscopic Aims
Patients and Methods
The aim of the study was to develop a quantitative scoring system
to predict whether a large-to-massive rotator cuff tear was arthroscopically
reparable prior to surgery. We conducted a retrospective review of the pre-operative MR imaging
and surgical records of 87 patients (87 shoulders) who underwent
arthroscopic repair of a large-to-massive rotator cuff tear. Patients
were divided into two groups, based on the surgical outcome of the
repair. Of the 87 patients, 53 underwent complete repair (Group
I) and 34 an incomplete repair (Group II). Pre-operative MR images
were reviewed to quantify several variables. Between-group differences
were evaluated and multiple logistic regression analysis was used
to calculate the predictive value of significant variables. The
reparability index (RI) was constructed using the odds ratios of
significant variables and a receiver operating characteristic curve
analysis performed to identify the optimal RI cutoff to differentiate
between the two groups.Aims
Patients and Methods
We present a case series of five patients who had revision surgery
following magnetic controlled growing rods (MGCR) for early onset
scoliosis. Metallosis was found during revision in four out of five
patients and we postulated a mechanism for rod failure based on
retrieval analysis. Retrieval analysis was performed on the seven explanted rods.
The mean duration of MCGR from implantation to revision was 35 months
(17 to 46). The mean age at revision was 12 years (7 to 15; four
boys, one girl).Aims
Patients and Methods
To evaluate whether an ultra-low-dose CT protocol can diagnose
selected limb fractures as well as conventional CT (C-CT). We prospectively studied 40 consecutive patients with a limb
fracture in whom a CT scan was indicated. These were scanned using
an ultra-low-dose CT Reduced Effective Dose Using Computed Tomography
In Orthopaedic Injury (REDUCTION) protocol. Studies from 16 selected
cases were compared with 16 C-CT scans matched for age, gender and
type of fracture. Studies were assessed for diagnosis and image
quality. Descriptive and reliability statistics were calculated.
The total effective radiation dose for each scanned site was compared.Aims
Patients and Methods
The purpose of this retrospective study was to differentiate
between the MRI features of normal post-operative change and those
of residual or recurrent disease after intralesional treatment of
an atypical cartilage tumour (ACT)/grade I chondrosarcoma. We reviewed the case notes, radiology and histology of 75 patients,
who had been treated for an ACT/grade I chondrosarcoma by curettage,
phenolisation and bone allografting between 1994 and 2005. The first
post-operative Gd-enhanced MRI scan was carried out within one year
of surgery. Patients had a minimum of two scans and a mean follow-up
of 72 months (13 to 169). Further surgery was undertaken in cases
of suspected recurrence.Aims
Patients and Methods
Myxofibrosarcomas (MFSs) are malignant soft-tissue sarcomas characteristically
presenting as painless slowly growing masses in the extremities.
Locally infiltrative growth means that the risk of local recurrence
is high. We reviewed our experience to make recommendations about
resection strategies and the role of the multidisciplinary team
in the management of these tumours. Patients with a primary or recurrent MFS who were treated surgically
in our unit between 1997 and 2012 were included in the study. Clinical
records and imaging were reviewed. A total of 50 patients with a
median age of 68.4 years (interquartile range 61.6 to 81.8) were
included. There were 35 men; 49 underwent surgery in our unit.Aims
Patients and Methods
We report the use of the distal radius and ulna (DRU) classification
for the prediction of peak growth (PG) and growth cessation (GC)
in 777 patients with idiopathic scoliosis. We compare this classification
with other commonly used parameters of maturity. The following data were extracted from the patients’ records
and radiographs: chronological age, body height (BH), arm span (AS),
date of menarche, Risser sign, DRU grade and status of the phalangeal
and metacarpal physes. The mean rates of growth were recorded according
to each parameter of maturity. PG was defined as the summit of the curve
and GC as the plateau in deceleration of growth. The rates of growth
at PG and GC were used for analysis using receiver operating characteristic
(ROC) curves to determine the strength and cutoff values of the
parameters of growth.Aims
Patients and Methods
Extendible endoprostheses have been available for more than 30
years and have become more sophisticated with time. The latest generation
is ‘non-invasive’ and can be lengthened with an external magnetic
force. Early results have shown a worryingly high rate of complications
such as infection. This study investigates the incidence of complications
and the need for further surgery in a cohort of patients with a
non-invasive growing endoprosthesis. Between 2003 and June 2014, 50 children (51 prostheses) had a
non-invasive growing prosthesis implanted for a primary bone sarcoma.
The minimum follow-up was 24 months for those who survived. Their
mean age was 10.4 years (6 to 14). The incidence of complications
and further surgery was documented.Aims
Patients and Methods
To determine the normal values and usefulness of the C1/4 space
available for spinal cord (SAC) ratio and C1 inclination angle,
which are new radiological parameters for assessing atlantoaxial
instability in children with Down syndrome. We recruited 272 children with Down syndrome (including 14 who
underwent surgical treatment), and 141 children in the control group.
All were aged between two and 11 years. The C1/4 SAC ratio, C1 inclination
angle, atlas-dens interval (ADI), and SAC were measured in those
with Down syndrome, and the C1/4 SAC ratio and C1 inclination angle
were measured in the control group.Aims
