There is no consensus on the benefit of arthroscopically
assisted reduction of the articular surface combined with fixation
using a volar locking plate for the treatment of intra-articular
distal radial fractures. In this study we compared the functional
and radiographic outcomes of fluoroscopically and arthroscopically
guided reduction of these fractures. Between February 2009 and May 2013, 74 patients with unilateral
unstable intra-articular distal radial fractures were randomised
equally into the two groups for treatment. The mean age of these
74 patients was 64 years (24 to 92). We compared functional outcomes
including active range of movement of the wrist, grip strength and Disabilities
of the Arm, Shoulder, and Hand scores at six and 48 weeks; and radiographic
outcomes that included gap, step, radial inclination, volar angulation
and ulnar variance. There were no significant differences between the techniques
with regard to functional outcomes or radiographic parameters. The
mean gap and step in the fluoroscopic and arthroscopic groups were
comparable at 0.9 mm (standard deviation Arthroscopic reduction conferred no advantage over conventional
fluoroscopic guidance in achieving anatomical reduction of intra-articular
distal radial fractures when using a volar locking plate. Cite this article:
Between 2002 and 2011, 81 patients with a traumatic total brachial
plexus injury underwent reconstruction by double free muscle transfer
(DFMT, 47 cases), single muscle transfer (SMT, 16 cases) or nerve
transfers (NT, 18 cases). They were evaluated for functional outcome and quality of life
(QoL) using the Disability of Arm, Shoulder and Hand questionnaire,
both pre- and post-operatively. The three groups were compared and
followed-up for at least 24 months.Aims
Methods
The objective of this study was to validate the
efficacy of Takeuchi classification for lateral hinge fractures
(LHFs) in open wedge high tibial osteotomy (OWHTO). In all 74 osteoarthritic
knees (58 females, 16 males; mean age 62.9 years, standard deviation
7.5, 42 to 77) were treated with OWHTO using a TomoFix plate. The
knees were divided into non-fracture (59 knees) and LHF (15 knees)
groups, and the LHF group was further divided into Takeuchi types
I, II, and III (seven, two, and six knees, respectively). The outcomes
were assessed pre-operatively and one year after OWHTO. Pre-operative
characteristics (age, gender and body mass index) showed no significant
difference between the two groups. The mean Japanese Orthopaedic
Association score was significantly improved one year after operation
regardless of the presence or absence of LHF (p = 0.0015, p <
0.001, respectively). However, six of seven type I cases had no
LHF-related complications; both type II cases had delayed union;
and of six type III cases, two had delayed union with correction
loss and one had overcorrection. These results suggest that Takeuchi
type II and III LHFs are structurally unstable compared with type
I. Cite this article:
The use of robotics in arthroplasty surgery is expanding rapidly as improvements in the technology evolve. This article examines current evidence to justify the usage of robotics, as well as the future potential in this emerging field.
Patients from a randomised trial on resurfacing
hip arthroplasty (RHA) (n = 36, 19 males; median age 57 years, 24
to 65) comparing a conventional 28 mm metal-on-metal total hip arthroplasty
(MoM THA) (n = 28, 17 males; median age 59 years, 37 to 65) and
a matched control group of asymptomatic patients with a 32 mm ceramic-on-polyethylene
(CoP) THA (n = 33, 18 males; median age 63 years, 38 to 71) were
cross-sectionally screened with metal artefact reducing sequence-MRI
(MARS-MRI) for pseudotumour formation at a median of 55 months (23
to 72) post-operatively. MRIs were scored by consensus according
to three different classification systems for pseudotumour formation. Clinical scores were available for all patients and metal ion
levels for MoM bearing patients. Periprosthetic lesions with a median volume of 16 mL (1.5 to
35.9) were diagnosed in six patients in the RHA group (17%), one
in the MoM THA group (4%) and six in the CoP group (18%). The classification
systems revealed no clear differences between the groups. Solid
lesions (n = 3) were exclusively encountered in the RHA group. Two patients
in the RHA group and one in the MoM THA group underwent a revision
for pseudotumour formation. There was no statistically significant
relationship between clinical scoring, metal ion levels and periprosthetic
lesions in any of the groups. Periprosthetic fluid collections are seen on MARS-MRI after conventional
CoP THA and RHA and may reflect a soft-tissue collection or effusion. Currently available MRI classification systems seem to score
these collections as pseudotumours, causing an-overestimatation
of the incidence of pseudotumours. Cite this article:
Osteosarcoma of the pelvis is a particularly difficult tumour
to treat as it often presents late, may be of considerable size
and/or associated with metastases when it presents, and is frequently
chondroid in origin and resistant to chemotherapy. The aim of this study was to review our experience of managing
this group of patients and to identify features predictive of a
poor outcome. Between 1983 and 2014, 121 patients, (74 females and 47 males)
were treated at a single hospital: 74 (61.2%) patients had a primary
osteosarcoma and 47 (38.8%) had an osteosarcoma which was secondary
either to Paget’s disease (22; 18.2%) or to previous pelvic irradiation
(25; 20.7%). The mean age of those with a primary osteosarcoma was 29.3 years
(nine to 76) and their mean follow-up 2.9 years (0 to 29). The mean
age of those with a secondary sarcoma was 61.9 years (15 to 85)
and their mean follow-up was one year (0 to 14). A total of 22 patients with a primary sarcoma (52.4%) and 20
of those with a secondary sarcoma (47.6%) had metastases at the
time of presentation. Aims
Patients and Methods
In this study of patients who underwent internal fixation without
fusion for a burst thoracolumbar or lumbar fracture, we compared
the serial changes in the injured disc height (DH), and the fractured
vertebral body height (VBH) and kyphotic angle between patients
in whom the implants were removed and those in whom they were not. Radiological
parameters such as injured DH, fractured VBH and kyphotic angle
were measured. Functional outcomes were evaluated using the Greenough
low back outcome scale and a VAS scale for pain. Between June 1996 and May 2012, 69 patients were analysed retrospectively;
47 were included in the implant removal group and 22 in the implant
retention group. After a mean follow-up of 66 months (48 to 107),
eight patients (36.3%) in the implant retention group had screw
breakage. There was no screw breakage in the implant removal group.
All radiological and functional outcomes were similar between these
two groups. Although solid union of the fractured vertebrae was
achieved, the kyphotic angle and the anterior third of the injured
DH changed significantly with time (p <
0.05). Methods
Results
Neuropathic changes in the foot are common with
a prevalence of approximately 1%. The diagnosis of neuropathic arthropathy
is often delayed in diabetic patients with harmful consequences
including amputation. The appropriate diagnosis and treatment can
avoid an extensive programme of treatment with significant morbidity
for the patient, high costs and delayed surgery. The pathogenesis
of a Charcot foot involves repetitive micro-trauma in a foot with impaired
sensation and neurovascular changes caused by pathological innervation
of the blood vessels. In most cases, changes are due to a combination
of both pathophysiological factors. The Charcot foot is triggered
by a combination of mechanical, vascular and biological factors
which can lead to late diagnosis and incorrect treatment and eventually
to destruction of the foot. This review aims to raise awareness of the diagnosis of the Charcot
foot (diabetic neuropathic osteoarthropathy and the differential
diagnosis, erysipelas, peripheral arterial occlusive disease) and
describe the ways in which the diagnosis may be made. The clinical
diagnostic pathways based on different classifications are presented. Cite this article:
There is no single standardised method of measuring
the orientation of the acetabular component on plain radiographs
after total hip arthroplasty. We assessed the reliability and accuracy
of three methods of assessing anteversion of the acetabular component
for 551 THAs using the PolyWare software and the methods of Liaw
et al, and of Woo and Morrey. All measurements of the three methods
had excellent intra- and inter-observer reliability. The values
of the PolyWare software, which determines version of the acetabular
component by edge detection were regarded as the reference standard.
Although the PolyWare software and the method of Liaw et al were similarly
precise, the method of Woo and Morrey was significantly less accurate
(p <
0.001). The method of Liaw et al seemed to be more accurate
than that of Woo and Morrey when compared with the measurements
using the PolyWare software. If the qualified lateral radiograph
was selected, anteversion measured using the method of Woo and Morrey
was considered to be relatively reliable. Cite this article:
In recent years, the plantaris tendon has been
implicated in the development of chronic painful mid-portion Achilles tendinopathy.
In some cases, a thickened plantaris tendon is closely associated
with the Achilles tendon, and surgical excision of the plantaris
tendon has been reported to be curative in patients who have not
derived benefit following conservative treatment and surgical interventions. The aim of this review is to outline the basic aspects of, and
the recent research findings, related to the plantaris tendon, covering
anatomical and clinical studies including those dealing with histology,
imaging and treatment. Cite this article
We performed a retrospective, comparative study of elderly patients
with an increased risk from anaesthesia who had undergone either
anterior screw fixation (ASF) or halo vest immobilisation (HVI)
for a type II odontoid fracture. A total of 80 patients aged 65 years or more who had undergone
either ASF or HVI for a type II odontoid fracture between 1988 and
2013 were reviewed. There were 47 women and 33 men with a mean age
of 73 (65 to 96; standard deviation 7). All had an American Society
of Anesthesiologists score of 2 or more.Aims
