The October 2014 Foot &
Ankle Roundup360 looks at: multilayer compression bandaging superior for post-traumatic ankle oedema; compression stockings for ankle fractures; weight bearing ok in Achilles tendon ruptures; MRI findings can predict ankle sprain symptoms; salvage for malreduced ankle fractures; locking fibular plates are more expensive; is fixation better early or late in pilon fractures?; and calcaneal fracture fixation not for subtalar arthropathy
High-quality randomised controlled trials (RCTs)
evaluating surgical therapies are fundamental to the delivery of
evidence-based orthopaedics. Orthopaedic clinical trials have unique
challenges; however, when these challenges are overcome, evidence
from trials can be definitive in its impact on surgical practice.
In this review, we highlight several issues that pose potential
challenges to orthopaedic investigators aiming to perform surgical randomised
controlled trials. We begin with a discussion on trial design issues,
including the ethics of sham surgery, the importance of sample size,
the need for patient-important outcomes, and overcoming expertise
bias. We then explore features surrounding the execution of surgical
randomised trials, including ethics review boards, the importance
of organisational frameworks, and obtaining adequate funding. Cite this article:
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
To assess the responsiveness and ceiling/floor effects of the Forgotten Joint Score -12 and to compare these with that of the more widely used Oxford Hip Score (OHS) in patients six and 12 months after primary total hip arthroplasty. We prospectively collected data at six and 12 months following total hip arthroplasty from 193 patients undergoing surgery at a single centre. Ceiling effects are outlined with frequencies for patients obtaining the lowest or highest possible score. Change over time from six months to 12 months post-surgery is reported as effect size (Cohen’s d).Objectives

Single event multilevel surgery (SEMLS) has been shown to improve
gait in children with cerebral palsy (CP). However, there is limited
evidence regarding long-term outcomes and factors influencing them. In total 39 children (17 females and 22 males; mean age at SEMLS
ten years four months, standard deviation 37 months) with bilateral
CP (20 Gross Motor Function Classification System (GMFCS) level
II and 19 GMFCS level III) treated with SEMLS were included. Children
were evaluated using gait analysis and the Gait Deviation Index
(GDI) before SEMLS and one, two to three, five and at least ten
years after SEMLS. A linear mixed model was used to estimate the
effect of age at the surgery, GMFCS and follow-up period on GDI. Aims

Surgical intervention in patients with bone metastases from breast
cancer is dependent on the estimated survival of the patient. The
purpose of this paper was to identify factors that would predict
survival so that specific decisions could be made in terms of surgical
(or non-surgical) management. The records of 113 consecutive patients (112 women) with metastatic
breast cancer were analysed for clinical, radiological, serological
and surgical outcomes. Their median age was 61 years (interquartile
range 29 to 90) and the median duration of follow-up was 1.6 years

This study aimed to determine the relationship between pedicle-lengthening
distance and bulge-canal volume ratio in cases of lumbar spinal
stenosis, to provide a theoretical basis for the extent of lengthening
in pedicle-lengthening osteotomies. Three-dimensional reconstructions of CT images were performed
for 69 patients (33 men and 36 women) (mean age 49.96 years; 24
to 81). Simulated pedicle-lengthening osteotomies and disc bulge
and spinal canal volume calculations were performed using Mimics
software. Aims

Revision total knee arthroplasty (TKA) is a complex
procedure which carries both a greater risk for patients and greater
cost for the treating hospital than does a primary TKA. As well
as the increased cost of peri-operative investigations, blood transfusions,
surgical instrumentation, implants and operating time, there is
a well-documented increased length of stay which accounts for most
of the actual costs associated with surgery. We compared revision surgery for infection with revision for
other causes (pain, instability, aseptic loosening and fracture).
Complete clinical, demographic and economic data were obtained for
168 consecutive revision TKAs performed at a tertiary referral centre
between 2005 and 2012. Revision surgery for infection was associated with a mean length
of stay more than double that of aseptic cases (21.5 Current NHS tariffs do not fully reimburse the increased costs
of providing a revision knee surgery service. Moreover, especially
as greater costs are incurred for infected cases. These losses may
adversely affect the provision of revision surgery in the NHS. Cite this article:
The purpose of this study was to develop a prognostic model for
predicting survival of patients undergoing surgery owing to metastatic
bone disease (MBD) in the appendicular skeleton. We included a historical cohort of 130 consecutive patients (mean
age 64 years, 30 to 85; 76 females/54 males) who underwent joint
arthroplasty surgery (140 procedures) owing to MBD in the appendicular
skeleton during the period between January 2003 and December 2008.

A total of 30 patients with thoracolumbar/lumbar adolescent idiopathic
scoliosis (AIS) treated between 1989 and 2000 with anterior correction
and fusion surgery using dual-rod instrumentation were reviewed. Radiographic parameters and clinical outcomes were compared among
patients with lowest instrumented vertebra (LIV) at the lower end
vertebra (LEV; EV group) (n = 13) and those treated by short fusion

The December 2014 Foot &
Ankle Roundup360 looks at: Charcot feet, biomarkers and diabetes; weight bearing following Achilles tendon rupture; endobuttons and mal-reduced diastasis; evidence for stem cell therapies in osteochondral lesions of the talus; syndesmosis fixation in SER ankle fractures; and self-reporting for foot and ankle outcomes.
The purpose of this study was to evaluate the
effect of various non-operative modalities of treatment (transcutaneous
electrical nerve stimulation (TENS); neuromuscular electrical stimulation
(NMES); insoles and bracing) on the pain of osteoarthritis (OA)
of the knee. We conducted a systematic review according to the Preferred Reporting
Items for Systematic Reviews and Meta-Analyses guidelines to identify
the therapeutic options which are commonly adopted for the management
of osteoarthritis (OA) of the knee. The outcome measurement tools used in the different studies were
the visual analogue scale and The Western Ontario and McMaster Universities
Arthritis Index pain index: all pain scores were converted to a
100-point scale. A total of 30 studies met our inclusion criteria: 13 on insoles,
seven on TENS, six on NMES, and four on bracing. The standardised
mean difference (SMD) in pain after treatment with TENS was 1.796,
which represented a significant reduction in pain. The significant
overall effect estimate for NMES on pain was similar to that of
TENS, with a SMD of 1.924. The overall effect estimate of insoles
on pain was a SMD of 0.992. The overall effect of bracing showed
a significant reduction in pain of 1.34. Overall, all four non-operative modalities of treatment were
found to have a significant effect on the reduction of pain in OA
of the knee. This study shows that non-operative physical modalities of treatment
are of benefit when treating OA of the knee. However, much of the
literature reviewed evaluates studies with follow-up of less than
six months: future work should aim to evaluate patients with longer
follow-up. Cite this article:
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 evaluated clinical and radiographic outcomes of total shoulder
arthroplasty (TSA) using the second-generation Trabecular Metal
(TM) Glenoid component. The first generation component was withdrawn
in 2005 after a series of failures were reported. Between 2009 and
2012, 40 consecutive patients with unilateral TSA using the second-generation
component were enrolled in this clinical study. The mean age of
the patients was 63.8 years (40 to 75) and the mean follow-up was
38 months (24 to 42). Patients were evaluated using the Constant score (CS), the American
Shoulder and Elbow Surgeons (ASES) score and routine radiographs.Aims
