Approximately half of all hip fractures are displaced intracapsular fractures. The standard treatment for these fractures is either hemiarthroplasty or total hip arthroplasty. The recent National Institute for Health and Care Excellence (NICE) guidance on hip fracture management recommends the use of ‘proven’ cemented stem arthroplasty with an Orthopaedic Device Evaluation Panel (ODEP) rating of at least 3B (97% survival at three years). The Thompsons prosthesis is currently lacking an ODEP rating despite over 50 years of clinical use, likely due to the paucity of implant survival data. Nationally, adherence to these guidelines is varied as there is debate as to which prosthesis optimises patient outcomes. This study design is a multi-centre, multi-surgeon, parallel, two arm, standard-of-care pragmatic randomised controlled trial. It will be embedded within the WHiTE Comprehensive Cohort Study (ISRCTN63982700). The main analysis is a two-way equivalence comparison between Hemi-Thompson and Hemi-Exeter polished taper with Unitrax head. Secondary outcomes will include radiological leg length discrepancy measured as per Bidwai and Willett, mortality, re-operation rate and indication for re-operation, length of index hospital stay and revision at four months. This study will be supplemented by the NHFD (National Hip Fracture Database) dataset.Background
Design
Deep bone and joint infections (DBJI) are directly intertwined with health, demographic change towards an elderly population, and wellbeing. The elderly human population is more prone to acquire infections, and the consequences such as pain, reduced quality of life, morbidity, absence from work and premature retirement due to disability place significant burdens on already strained healthcare systems and societal budgets. DBJIs are less responsive to systemic antibiotics because of poor vascular perfusion in necrotic bone, large bone defects and persistent biofilm-based infection. Emerging bacterial resistance poses a major threat and new innovative treatment modalities are urgently needed to curb its current trajectory. We present a new biphasic ceramic bone substitute consisting of hydroxyapatite and calcium sulphate for local antibiotic delivery in combination with bone regeneration. Gentamicin release was measured in four setups: 1) Objectives
Materials and Methods
The biomembrane (induced membrane) formed around polymethylmethacrylate (PMMA) spacers has value in clinical applications for bone defect reconstruction. Few studies have evaluated its cellular, molecular or stem cell features. Our objective was to characterise induced membrane morphology, molecular features and osteogenic stem cell characteristics. Following Institutional Review Board approval, biomembrane specimens were obtained from 12 patient surgeries for management of segmental bony defects (mean patient age 40.7 years, standard deviation 14.4). Biomembranes from nine tibias and three femurs were processed for morphologic, molecular or stem cell analyses. Gene expression was determined using the Affymetrix GeneChip Operating Software (GCOS). Molecular analyses compared biomembrane gene expression patterns with a mineralising osteoblast culture, and gene expression in specimens with longer spacer duration (> 12 weeks) with specimens with shorter durations. Statistical analyses used the unpaired student Objectives
Methods
Fractures of the proximal femur are one of the
greatest challenges facing the medical community, constituting a
heavy socioeconomic burden worldwide. Controversy exists regarding
the optimal treatment for patients with unstable trochanteric proximal
femoral fractures. The recognised treatment alternatives are extramedullary
fixation usually with a sliding hip screw and intramedullary fixation
with a cephalomedullary nail. Current evidence suggests that best
results and lowest complication rates occur using a sliding hip screw.
Complications in these difficult fractures are relatively common
regardless of type of treatment. We believe that a novel device,
the X-Bolt dynamic plating system, may offer superior fixation over
a sliding hip screw with lower reoperation risk and better function.
We therefore propose to investigate the clinical effectiveness of
the X-bolt dynamic plating system compared with standard sliding
hip screw fixation within the framework of a the larger WHiTE (Warwick
Hip Trauma Evaluation) Comprehensive Cohort Study. Cite this article:
Fractures of the proximal femur are one of the
greatest challenges facing the medical community, constituting a
heavy socioeconomic burden worldwide. Controversy exists regarding
the optimal treatment for independent patients with displaced intracapsular fractures
of the proximal femur. The recognised alternatives are hemiarthroplasty
and total hip replacement. At present there is no established standard
of care, with both types of arthroplasty being used in many centres.
The principal advantages of total hip replacement are a functional
benefit over hemiarthroplasty and a reduced risk of revision surgery.
The principal criticism is the increased risk of dislocation. We
believe that an alternative acetabular component may reduce the
risk of dislocation but still provide the functional benefit of
total hip replacement in these patients. We therefore propose to
investigate the dislocation risk of a dual-mobility acetabular component
compared with standard polyethylene component in total hip replacement
for independent patients with displaced intracapsular fractures
of the proximal femur within the framework of the larger WHiTE (Warwick
Hip Trauma Evaluation) Comprehensive Cohort Study. Cite this article:
Fractures of the proximal femur are one of the
greatest challenges facing the medical community, constituting a
heavy socioeconomic burden worldwide. The National Hip Fracture
Audit currently provides a framework for service evaluation. This
evaluation is based upon the assessment of process rather than assessment
of patient-centred outcome and therefore it fails to provide meaningful
data regarding the clinical effectiveness of treatments. This study
aims to capture data from the cohort of patients who present with
a fracture of the proximal femur at a single United Kingdom Major
Trauma Centre. Patient-centred outcomes will be recorded and provide
a baseline cohort within which to test the clinical effectiveness
of experimental interventions.
A rigorous approach to developing, delivering and documenting
rehabilitation within randomised controlled trials of surgical interventions
is required to underpin the generation of reliable and usable evidence.
This article describes the key processes used to ensure provision
of good quality and comparable rehabilitation to all participants
of a multi-centre randomised controlled trial comparing surgery
with conservative treatment of proximal humeral fractures in adults. These processes included the development of a patient information
leaflet on self-care during sling immobilisation, the development
of a basic treatment physiotherapy protocol that received input
and endorsement by specialist physiotherapists providing patient
care, and establishing an expectation for the provision of home
exercises. Specially designed forms were also developed to facilitate
reliable reporting of the physiotherapy care that patients received.Objectives
Methods
To study the measurement properties of a joint specific patient
reported outcome measure, a measure of capability and a general
health-related quality of life (HRQOL) tool in a large cohort of
patients with a hip fracture. Responsiveness and associations between the Oxford Hip Score
(a hip specific measure: OHS), ICEpop CAPability (a measure of capability
in older people: ICECAP-O) and EuroQol EQ-5D (general health-related
quality of life measure: EQ-5D) were assessed using data available
from two large prospective studies. The three outcome measures were assessed
concurrently at a number of fixed follow-up time-points in a consecutive
sequence of patients, allowing direct assessment of change from
baseline, inter-measure associations and validity using a range
of statistical methods.Objectives
Methods
To determine the morbidity and mortality outcomes of patients
presenting with a fractured neck of femur in an Australian context.
Peri-operative variables related to unfavourable outcomes were identified
to allow planning of intervention strategies for improving peri-operative
care. We performed a retrospective observational study of 185 consecutive
adult patients admitted to an Australian metropolitan teaching hospital
with fractured neck of femur between 2009 and 2010. The main outcome
measures were 30-day and one-year mortality rates, major complications
and factors influencing mortality. Objectives
Methods
To investigate the differences of open reduction and internal
fixation (ORIF) of complex AO Type C distal radius fractures between
two different models of a single implant type. A total of 136 patients who received either a 2.4 mm (n = 61)
or 3.5 mm (n = 75) distal radius locking compression plate (LCP
DR) using a volar approach were followed over two years. The main
outcome measurements included motion, grip strength, pain, and the
scores of Gartland and Werley, the Short-Form 36 (SF-36) and the
Disabilities of the Arm, Shoulder, and Hand (DASH). Differences
between the treatment groups were evaluated using regression analysis
and the likelihood ratio test with significance based on the Bonferroni
corrected p-value of <
0.003.Objectives
