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
There are various pin-in-plaster methods for treating fractures
of the distal radius. The purpose of this study is to introduce
a modified technique of ‘pin in plaster’. Fifty-four patients with fractures of the distal radius were
followed for one year post-operatively. Patients were excluded if
they had type B fractures according to AO classification, multiple
injuries or pathological fractures, and were treated more than seven
days after injury. Range of movement and functional results were
evaluated at three and six months and one and two years post-operatively.
Radiographic parameters including radial inclination, tilt, and
height, were measured pre- and post-operatively.Objectives
Methods
We report a new surgical technique of open carpal
tunnel release with subneural reconstruction of the transverse carpal
ligament and compare this with isolated open and endoscopic carpal
tunnel release. Between December 2007 and October 2011, 213 patients with carpal
tunnel syndrome (70 male, 143 female; mean age 45.6 years; 29 to
67) were recruited from three different centres and were randomly
allocated to three groups: group A, open carpal tunnel release with
subneural reconstruction of the transverse carpal ligament (n =
68); group B, isolated open carpal tunnel release (n = 92); and
group C, endoscopic carpal tunnel release (n = 53). At a mean final follow-up of 24 months (22 to 26), we found no
significant difference between the groups in terms of severity of
symptoms or lateral grip strength. Compared with groups B and C,
group A had significantly better functional status, cylindrical
grip strength and pinch grip strength. There were significant differences
in Michigan Hand Outcome scores between groups A and B, A and C,
and B and C. Group A had the best functional status, cylindrical
grip strength, pinch grip strength and Michigan Hand Outcome score. Subneural reconstruction of the transverse carpal ligament during
carpal tunnel decompression maximises hand strength by stabilising
the transverse carpal arch. Cite this article:
We present an economic evaluation using data
from the Distal Radius Acute Fracture Fixation Trial (DRAFFT) to compare
the relative cost effectiveness of percutaneous Kirschner wire (K-wire)
fixation and volar locking-plate fixation for patients with dorsally-displaced
fractures of the distal radius. The cost effectiveness analysis (cost per quality-adjusted life
year; QALY) was derived from a multi-centre, two-arm, parallel group,
assessor-blind, randomised controlled trial which took place in
18 trauma centres in the United Kingdom. Data from 460 patients
were available for analysis, which includes both a National Health
Service cost perspective including costs of surgery, implants and
healthcare resource use over a 12-month period after surgery, and
a societal perspective, which includes the cost of time off work
and the need for additional private care. There was only a small difference in QALYs gained for patients
treated with locking-plate fixation over those treated with K-wires.
At a mean additional cost of £714 (95% confidence interval 588 to
865) per patient, locking-plate fixation presented an incremental
cost effectiveness ratio (ICER) of £89 322 per QALY within the first
12 months of treatment. Sensitivity analyses were undertaken to
assess the ICER of locking-plate fixation compared with K-wires.
These were greater than £30 000. Compared with locking-plate fixation, K-wire fixation is a ‘cost
saving’ intervention, with similar health benefits. Cite this article:
The aim of this systematic literature review was to assess the clinical level of evidence of commercially available demineralised bone matrix (DBM) products for their use in trauma and orthopaedic related surgery. A total of 17 DBM products were used as search terms in two available databases: Embase and PubMed according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses statement. All articles that reported the clinical use of a DBM-product in trauma and orthopaedic related surgery were included.Objectives
Methods
Infection of implants is a major problem in elective and trauma surgery. Heating is an effective way to reduce the bacterial load in food preparation, and studies on hyperthermia treatment for cancer have shown that it is possible to heat metal objects with pulsed electromagnetic fields selectively (PEMF), also known as induction heating. We therefore set out to answer the following research question: is non-contact induction heating of metallic implants effective in reducing bacterial load Titanium alloy cylinders (Ti6Al4V) were exposed to PEMF from an induction heater with maximum 2000 watts at 27 kHz after being contaminated with five different types of micro-organisms: Objectives

Traditionally, informed consent for clinical
research involves the patient reading an approved Participant Information
Sheet, considering the information presented and having as much time
as they need to discuss the study information with their friends
and relatives, their clinical care and the research teams. This
system works well in the ‘planned’ or ‘elective’ setting. But what
happens if the patient requires urgent treatment for an injury or emergency? This article reviews the legal framework which governs informed
consent in the emergency setting, discusses how the approach taken
may vary according to the details of the emergency and the treatment
required, and reports on the patients’ view of providing consent
following a serious injury. We then provide some practical tips
for managing the process of informed consent in the context of injuries
and emergencies. Cite this article:
The eccentric glenosphere was principally introduced into reverse
shoulder arthroplasty to reduce the incidence of scapular notching.
There is only limited information about the influence of its design
on deltoid power and joint reaction forces. The aim of our study was to investigate how the diameter and
eccentricity of the glenosphere affect the biomechanics of the deltoid
and the resultant joint reaction forces. Different sizes of glenosphere and eccentricity were serially
tested in ten cadaveric shoulders using a custom shoulder movement
simulator.Aims
Methods
We hypothesised that the use of pulsed electromagnetic
field (PEMF) bone growth stimulation in acute scaphoid fractures
would significantly shorten the time to union and reduce the number
of nonunions in a randomised, double-blind, placebo-controlled multicentre
trial. A total of 102 patients (78 male, 24 female; mean age 35
years (18 to 77)) from five different medical centres with a unilateral
undisplaced acute scaphoid fracture were randomly allocated to PEMF
(n = 51) or placebo (n = 51) and assessed with regard to functional
and radiological outcomes (multiplanar reconstructed CT scans) at
6, 9, 12, 24 and 52 weeks. The overall time to clinical and radiological healing
did not differ significantly between the active PEMF group and the
placebo group. We concluded that the addition of PEMF bone growth
stimulation to the conservative treatment of acute scaphoid fractures
does not accelerate bone healing. Cite this article:
The aim of this study was to compare the Push Ortho Thumb Brace
CMC and a custom-made orthosis in the treatment of patients with
primary osteoarthritis of the carpometacarpal joint of the thumb.
Our outcome measures were pain scores, tests of hand function, patient
satisfaction and patient preference. A multicentre crossover randomised controlled trial was conducted
which included 63 patients (44 women) with primary osteoarthritis
of the carpometacarpal joint of the thumb. Of these, 59 patients
with a mean age of 60.1 years (standard deviation 8.2), completed
the study. Patients used both orthoses for two weeks with a two-week washout
period in-between. Pain was measured on a 10-cm visual analogue
scale. Hand function was assessed using the Jebsen Taylor Hand Function
test, Nine Hole Peg Test, key grip, pinch grip and Functional Index
for Hand Osteoarthritis. Patient preference was assessed using the
Dutch version of the Quebec User Evaluation of Satisfaction with
Assistive Technology score.Aims
