The aims of this study were to identify the early
in-hospital mortality rate after hip fracture, identify factors associated
with this mortality, and identify the cause of death in these patients.
A retrospective cohort study was performed on 4426 patients admitted
to our institution between the 1 January 2006 and 31 December 2013
with a hip fracture (1128 male (26%), mean age 82.0 years (60 to
105)). Admissions increased annually, but despite this 30-day mortality
decreased from 12.1% to 6.5%; 77% of these were in-hospital deaths.
Male gender (odds ratio (OR) 2.0, 95% confidence interval (CI) 1.3
to 3.0), increasing age (age ≥ 91; OR 4.1, 95% CI 1.4 to 12.2) and
comorbidity (American Society of Anesthesiologists grades 3 to 5;
OR 4.2, 95% CI 2.0 to 8.7) were independently and significantly
associated with increased odds of in-hospital mortality. From 220
post-mortem reports, the most common causes of death were respiratory
infections (35%), ischaemic heart disease (21%), and cardiac failure
(13%). A sub-group of hip fracture patients at highest risk of early
death can be identified with these risk factors, and the knowledge
of the causes of death can be used to inform service improvements
and the development of a more didactic care pathway, so that multidisciplinary
intervention can be focused for this sub-group in order to improve
their outcome. Cite this article:
The purpose of the study was to investigate whether closed intramedullary
(IM) nailing with percutaneous cement augmentation is better than
conventional closed nailing at relieving pain and suppressing tumours
in patients with metastases of the femur and humerus. A total of 43 patients (27 men, 16 women, mean age 63.7 years,

Patients and Methods
Degenerative problems of the hip in patients
with childhood and adult onset neuromuscular disorders can be challenging
to treat. Many orthopaedic surgeons are reluctant to recommend total
hip replacement (THR) for patients with underlying neuromuscular
disorders due to the perceived increased risks of dislocation, implant loosening,
and lack of information about the functional outcomes and potential
benefits of these procedures in these patients. Modular femoral
components and alternative bearings which facilitate the use of
large femoral heads, constrained acetabular components and perhaps
more importantly, a better understanding about the complications
and outcomes of THR in the patient with neuromuscular disorders,
make this option viable. This paper will review the current literature
and our experience with THR in the more frequently encountered neuromuscular
disorders. Cite this article:
The December 2014 Knee Roundup360 looks at: national guidance on arthroplasty thromboprophylaxis is effective; unicompartmental knee replacement has the edge in terms of short-term complications; stiff knees, timing and manipulation; neuropathic pain and total knee replacement; synovial fluid α-defensin and CRP: a new gold standard in joint infection diagnosis?; how to assess anterior knee pain?; where is the evidence? Five new implants under the spotlight; and a fresh look at ACL reconstruction
The primary aim of this study was to analyse the position of
the acetabular and femoral components in total hip arthroplasty
undertaken using an anterior surgical approach. In a prospective, single centre study, we used the EOS imaging
system to analyse the position of components following THA performed
via the anterior approach in 102 patients (103 hips) with a mean
age of 64.7 years (Aims
Patients and Methods
The highly cross-linked polyethylene Exeter RimFit flanged cemented
acetabular component was introduced in the United Kingdom in 2010.
This study aimed to examine the rates of emergence of radiolucent
lines observed when the Rimfit acetabular component was implanted
at total hip arthroplasty (THA) using two different techniques: firstly,
the ‘rimcutter’ technique in which the flange sits on a pre-prepared
acetabular rim; and secondly, the ‘trimmed flange’ technique in
which the flange is trimmed and the acetabular component is seated
inside the rim of the acetabulum. The radiographs of 150 THAs (75 ‘rimcutter’, 75 ‘trimmed flange’)
involving this component were evaluated to assess for radiolucencies
at the cement/bone interface by three observers. Aims

Hips with metal-on-metal total hip arthroplasty (MoM THA) have a high rate of adverse local tissue reactions (ALTR), often associated with hypersensitivity reactions. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) measures tissue perfusion with the parameter Ktrans (volume transfer constant of contrast agent). Our purpose was 1) to evaluate the feasibility of DCE-MRI in patients with THA and 2) to compare DCE-MRI in patients with MoM bearings with metal-on-polyethylene (MoP) bearings, hypothesising that the perfusion index Ktrans in hips with MoM THA is higher than in hips with MoP THA. In this pilot study, 16 patients with primary THA were recruited (eight MoM, eight MoP). DCE-MRI of the hip was performed at 1.5 Tesla (T). For each patient, Ktrans was computed voxel-by-voxel in all tissue lateral to the bladder. The mean Ktrans for all voxels was then calculated. These values were compared with respect to implant type and gender, and further correlated with clinical parameters.Objectives
Methods
A total of 219 hips in 192 patients aged between
18 and 65 years were randomised to 28-mm metal-on-metal uncemented
total hip replacements (THRs, 107 hips) or hybrid hip resurfacing
(HR, 112 hips). At a mean follow-up of eight years (6.6 to 9.3)
there was no significant difference between the THR and HR groups
regarding rate of revision (4.0% (4 of 99) Cite this article:
Given the increasing number of total hip arthroplasty
procedures being performed annually, it is imperative that orthopaedic
surgeons understand factors responsible for instability. In order
to treat this potentially complex problem, we recommend correctly
classifying the type of instability present based on component position, abductor
function, impingement, and polyethylene wear. Correct classification
allows the treating surgeon to choose the appropriate revision option
that ultimately will allow for the best potential outcome. Cite this article:
The use of joint-preserving surgery of the hip
has been largely abandoned since the introduction of total hip replacement.
However, with the modification of such techniques as pelvic osteotomy,
and the introduction of intracapsular procedures such as surgical
hip dislocation and arthroscopy, previously unexpected options for
the surgical treatment of sequelae of childhood conditions, including
developmental dysplasia of the hip, slipped upper femoral epiphysis
and Perthes’ disease, have become available. Moreover, femoroacetabular
impingement has been identified as a significant aetiological factor
in the development of osteoarthritis in many hips previously considered to
suffer from primary osteoarthritis. As mechanical causes of degenerative joint disease are now recognised
earlier in the disease process, these techniques may be used to
decelerate or even prevent progression to osteoarthritis. We review
the recent development of these concepts and the associated surgical
techniques. Cite this article:
Surface hip replacement (SHR) is generally used
in younger, active patients as an alternative conventional total
hip replacement in part because of the ability to preserve femoral
bone. This major benefit of surface replacement will only hold true
if revision procedures of SHRs are found to provide good clinical
results. A retrospective review of SHR revisions between 2007 and 2012
was presented, and the type of revision and aetiologies were recorded.
There were 55 SHR revisions, of which 27 were in women. At a mean
follow-up of 2.3 years (0.72 to 6.4), the mean post-operative Harris
hip score (HHS) was 94.8 (66 to 100). Overall 23 were revised for mechanical
reasons, nine for impingement, 13 for metallosis, nine for unexplained
pain and one for sepsis. Of the type of revision surgery performed,
14 were femoral-only revisions; four were acetabular-only revisions,
and 37 were complete revisions. We did not find that clinical scores were significantly different
between gender or different types of revisions. However, the mean
post-operative HHS was significantly lower in patients revised for
unexplained pain compared with patients revised for mechanical reasons
(86.9 (66 to 100) Based on the overall clinical results, we believe that revision
of SHR can have good or excellent results and warrants a continued
use of the procedure in selected patients. Close monitoring of these
patients facilitates early intervention, as we believe that tissue
damage may be related to the duration of an ongoing problem. There
should be a low threshold to revise a surface replacement if there
is component malposition, rising metal ion levels, or evidence of
soft-tissue abnormalities. Cite this article:
We present a case series of ten metal-on-polyethylene total hip
arthroplasties (MoP THAs) with delayed dislocation associated with
unrecognised adverse local tissue reaction due to corrosion at the
trunnion and pseudotumour formation. The diagnosis was not suspected in nine of the ten patients (six
female/four male; mean age 66 years), despite treatment in a specialist
unit (mean time from index surgery to revision was 58 months, 36
to 84). It was identified at revision surgery and subsequently confirmed
by histological examination of resected tissue. Pre-operative assessment
and culture results ruled out infection. A variety of treatment
strategies were used, including resection of the pseudotumour and
efforts to avoid recurrent dislocation. Aims
Methods
Excision of the proximal femur for tumour with
prosthetic reconstruction using a bipolar femoral head places a considerable
load on the unreplaced acetabulum. We retrospectively reviewed the changes which occur around the
affected hip joint by evaluating the post-operative radiographs
of 65 consecutive patients who underwent proximal prosthetic arthroplasty
of the femur, and in whom an acetabular component had not been used.
There were 37 men and 28 women with a mean age of 57.3 years (17
to 93). Radiological assessment included the extent of degenerative
change in the acetabulum, heterotopic ossification, and protrusio
acetabuli. The mean follow-up was 9.1 years (2 to 11.8). Degenerative changes
in the acetabulum were seen in three patients (4.6%), Brooker grade
1 or 2 heterotopic ossification in 17 (26%) and protrusion of the
prosthetic head in nine (13.8%). A total of eight patients (12.3%) needed a revision. Five were
revised to the same type of prosthesis and three (4.6%) were converted
to a total hip arthroplasty. We conclude that radiological evidence of degenerative change,
heterotopic ossification and protrusion occur in a few patients
who undergo prosthetic arthroplasty of the proximal femur for tumour.
The limited extent of these changes and the lack of associated symptoms
do not justify the routine arthroplasty of the acetabulum in these patients. Cite this article:
We undertook a retrospective comparative study
of all patients with an unstable slipped capital femoral epiphysis presenting
to a single centre between 1998 and 2011. There were 45 patients
(46 hips; mean age 12.6 years; 9 to 14); 16 hips underwent intracapsular
cuneiform osteotomy and 30 underwent pinning Pinning Non-emergency intracapsular osteotomy may have a protective effect
on the epiphyseal vasculature and should be undertaken with a delay
of at least two weeks. The place of emergency pinning Cite this article:
