Radiostereometric analysis (RSA) allows an extremely accurate
measurement of early micromotion of components following arthroplasty. In this study, RSA was used to measure the migration of 11 partially
cemented fluted pegged glenoid components in patients with osteoarthritis
who underwent total shoulder arthroplasty using an improved surgical
technique (seven men, four women, mean age 68). Patients were evaluated
clinically using the American Shoulder and Elbow Surgeons (ASES)
and Constant-Murley scores and by CT scans two years post-operatively. Aims
Patients and Methods
The aim of this study was to assess the current available evidence
about when patients might resume driving after elective, primary
total hip (THA) or total knee arthroplasty (TKA) undertaken for
osteoarthritis (OA). In February 2016, EMBASE, MEDLINE, Web of Science, Scopus, Cochrane,
PubMed Publisher, CINAHL, EBSCO and Google Scholar were searched
for clinical studies reporting on ‘THA’, ‘TKA’, ‘car driving’, ‘reaction
time’ and ‘brake response time’. Two researchers (CAV and JJT) independently
screened the titles and abstracts for eligibility and assessed the
risk of bias. Both fixed and random effects were used to pool data
and calculate mean differences (MD) and 95% confidence intervals
(CI) between pre- and post-operative total brake response time (TBRT).Aims
Materials and Methods
The aim of this study was to compare the effect of a percutaneous
radiofrequency heat lesion at the medial branch of the primary dorsal
ramus with a sham procedure, for the treatment of lumbar facet joint
pain. A randomised sham-controlled double blind multicentre trial was
carried out at the multidisciplinary pain centres of two hospitals.
A total of 60 patients aged >
18 years with a history and physical
examination suggestive of facet joint pain and a decrease of ≥ 2
on a numerical rating scale (NRS 0 to 10) after a diagnostic facet
joint test block were included. In the treatment group, a percutaneous
radiofrequency heat lesion (80oC during 60 seconds per
level) was applied to the medial branch of the primary dorsal ramus.
In the sham group, the same procedure was undertaken without for
the radiofrequency lesion. Both groups also received a graded activity
physiotherapy programme. The primary outcome measure was decrease
in pain. A secondary outcome measure was the Global Perceived Effect scale
(GPE).Aims
Patients and Methods
We present a minimum 20-year follow-up study of 382 cemented
Exeter Universal total hip arthroplasties (350 patients) operated
on at a mean age of 66.3 years (17 to 94). All patients received the same design of femoral component, regardless
of the original diagnosis. Previous surgery had been undertaken
for 33 hips (8.6%). During the study period 218 patients with 236
hips (62%) died, 42 hips (11%) were revised and 110 hips (29%) in
96 patients were available for review. The acetabular components
were varied and some designs are now obsolete, however they were
all cemented.Aims
Patients and Methods
We performed a systematic review of the literature to determine the safety and efficacy of bone morphogenetic protein (BMP) compared with bone graft when used specifically for revision spinal fusion surgery secondary to pseudarthrosis. The MEDLINE, EMBASE and Cochrane Library databases were searched using defined search terms. The primary outcome measure was spinal fusion, assessed as success or failure in accordance with radiograph, MRI or CT scan review at 24-month follow-up. The secondary outcome measure was time to fusion.Objectives
Methods
Patients undergoing femoral lengthening by external fixation
tolerate treatment less well when compared to tibial lengthening.
Lengthening of the femur with an intramedullary device may have
advantages. We reviewed all cases of simple femoral lengthening performed
at our unit from 2009 to 2014. Cases of nonunions, concurrent deformities,
congenital limb deficiencies and lengthening with an unstable hip
were excluded, leaving 33 cases (in 22 patients; 11 patients had
bilateral procedures) for review. Healing index, implant tolerance
and complications were compared.Aims
Patients and Methods
The aim of this study was to compare the pain caused by the application
of a tourniquet after exsanguination of the upper limb with that
occurring after simple elevation. We used 26 healthy volunteers (52 arms), each of whom acted as
their own matched control. The primary outcome measure was the total pain experienced by
each volunteer while the tourniquet was inflated for 20 minutes.
This was calculated as the area under the pain curve for each individual
subject. Secondary outcomes were pain at each time point; the total
pain experienced during the recovery phase; the ability to tolerate the
tourniquet and the time for full recovery after deflation of the
tourniquet. Aims
Patients and Methods
Our aim was to compare kinematic with mechanical alignment in
total knee arthroplasty (TKA). We performed a prospective blinded randomised controlled trial
to compare the functional outcome of patients undergoing TKA in
mechanical alignment (MA) with those in kinematic alignment (KA).
A total of 71 patients undergoing TKA were randomised to either
kinematic (n = 36) or mechanical alignment (n = 35). Pre- and post-operative
hip-knee-ankle radiographs were analysed. The knee injury and osteoarthritis
outcome score (KOOS), American Knee Society Score, Short Form-36,
Euro-Qol (EQ-5D), range of movement (ROM), two minute walk, and timed
up and go tests were assessed pre-operatively and at six weeks,
three and six months and one year post-operatively.Aims
Patients and Methods
This non-blinded randomised controlled trial compared the effect
of patient-controlled epidural analgesia (PCEA) A total of 242 patients were randomised; 20 were excluded due
to failure of spinal anaesthesia leaving 109 patients in the PCEA
group and 113 in the LIA group. Patients were reviewed at six weeks
and one year post-operatively.Aims
Patients and Methods
Patellar instability most frequently presents
during adolescence. Congenital and infantile dislocation of the
patella is a distinct entity from adolescent instability and measurable
abnormalities may be present at birth. In the normal patellofemoral
joint an increase in quadriceps angle and patellar height are matched
by an increase in trochlear depth as the joint matures. Adolescent
instability may herald a lifelong condition leading to chronic disability
and arthritis. Restoring normal anatomy by trochleoplasty, tibial tubercle transfer
or medial patellofemoral ligament (MPFL) reconstruction in the young
adult prevents further instability. Although these techniques are
proven in the young adult, they may cause growth arrest and deformity
where the physis is open. A vigorous non-operative strategy may
permit delay of surgery until growth is complete. Where non-operative
treatment has failed a modified MPFL reconstruction may be performed
to maintain stability until physeal closure permits anatomical reconstruction.
If significant growth remains an extraosseous reconstruction of
the MPFL may impart the lowest risk to the physis. If minor growth
remains image intensifier guided placement of femoral intraosseous
fixation may impart a small, but acceptable, risk to the physis. This paper presents and discusses the literature relating to
adolescent instability and provides a framework for management of
these patients. Cite this article:
The aim of this study was to report the outcome following primary
fixation or a staged protocol for type C fractures of the tibial
plafond. We studied all patients who sustained a complex intra-articular
fracture (AO type C) of the distal tibia over an 11-year period.
The primary short-term outcome was infection. The primary long-term
outcome was the Foot and Ankle Outcome Score (FAOS).Aims
