Children presenting with Perthes’ disease before their sixth birthday are considered to have a good prognosis. We describe 166 hips in children in this age group. The mean age at onset of the disease was 44 months (22 to 72). Mild forms (Catterall I and II) were treated conservatively and severe forms (Catterall III and IV) either conservatively or operatively. The aim of the former treatment was to restrict weight-bearing. Operative treatment consisted of innominate osteotomy and was indicated by a Conway type-B appearance on the bone scan. All the patients were followed to skeletal maturity with a mean follow-up of 11 years (8 to 15). The end results were evaluated radiologically using the classifications of Stulberg and Mose. A total of 50 hips were Catterall grade-I or grade-II, 65 Catterall grade-III and 51 Catterall grade-IV. All hips with mild disease had a good result at skeletal maturity. Of the hips with severe disease 78 (67.3%) had good (Stulberg I and II), 26 (22.4%) fair (Stulberg III) and 12 (10.3%) poor results (Stulberg IV and V). Of the Catterall grade-III hips 38 were treated conservatively of which 31 (81.6%) had a good result, six (15.8%) a fair and one (2.6%) a poor result. Operative treatment was carried out on 27 Catterall grade-III hips, of which 21 (77.8%) had a good, four (14.8%) a fair and two (7.4%) a poor result. By comparison conservative treatment of 19 Catterall grade-IV hips led to ten (52.7%) good, seven (36.8%) fair and two (10.5%) poor results. Operative treatment was carried out on 32 Catterall grade-IV hips, of which 16 (50.0%) had a good, nine (28.1%) a fair and seven (21.9%) a poor result. We confirm that the prognosis in Perthes’ disease is generally good when the age at onset is less than six years. In severe disease there is no significant difference in
The number of arthroplasties of the hip and knee
is predicted to increase rapidly during the next 20 years. Accompanying
this is the dilemma of how to follow-up these patients appropriately.
Current guidelines recommend long-term follow-up to identify patients
with aseptic loosening, which can occur more than a decade postoperatively.
The current guidelines and practices of orthopaedic surgeons vary
widely. Existing models take up much clinical time and are expensive.
Pilot studies using ‘virtual’ clinics and advanced-practice physiotherapists
have shown promise in decreasing the time and costs for orthopaedic surgeons
and patients. This review discusses current practices and future trends in
the follow-up of patients who have an arthroplasty. Cite this article:
Objectives. The objective of this study was to compare the early migration
characteristics and functional outcome of the Triathlon cemented
knee prosthesis with its predecessor, the Duracon cemented knee
prosthesis (both Stryker). Methods. A total 60 patients were prospectively randomised and tibial
component migration was measured by radiostereometric analysis (RSA)
at three months, one year and two years; clinical outcome was measured
by the American Knee Society score and the Knee Osteoarthritis and

‘Big data’ is a term for data sets that are so
large or complex that traditional data processing applications are
inadequate. Billions of dollars have been spent on attempts to build predictive
tools from large sets of poorly controlled healthcare metadata.
Companies often sell reports at a physician or facility level based
on various flawed data sources, and comparative websites of ‘publicly
reported data’ purport to educate the public. Physicians should
be aware of concerns and pitfalls seen in such data definitions,
data clarity, data relevance, data sources and data cleaning when
evaluating analytic reports from metadata in health care. Cite this article:

The purpose of this study was to compare the
results of proximal and distal chevron osteotomy in patients with moderate
hallux valgus. We retrospectively reviewed 34 proximal chevron osteotomies without
lateral release (PCO group) and 33 distal chevron osteotomies (DCO
group) performed sequentially by a single surgeon. There were no
differences between the groups with regard to age, length of follow-up,
demographic or radiological parameters. The clinical results were
assessed using the American Orthopaedic Foot and Ankle Society (AOFAS)
scoring system and the radiological results were compared between
the groups. At a mean follow-up of 14.6 months (14 to 32) there were no significant
differences in the mean AOFAS scores between the DCO and PCO groups
(93.9 (82 to 100) and 91.8 (77 to 100), respectively; p = 0.176).
The mean hallux valgus angle, intermetatarsal angle and sesamoid
position were the same in both groups. The metatarsal declination
angle decreased significantly in the PCO group (p = 0.005) and the
mean shortening of the first metatarsal was significantly greater
in the DCO group (p <
0.001). We conclude that the clinical and radiological

The primary aim of this study was to define the standard minimum
follow-up required to produce a reliable estimate of the rate of
re-operation after radial head arthroplasty (RHA). The secondary
objective was to define the leading reasons for re-operation. Four electronic databases, between January 2000 and March 2017
were searched. Articles reporting reasons for re-operation (Group
I) and results (Group II) after RHA were included. In Group I, a
meta-analysis was performed to obtain the standard minimum follow-up,
the mean time to re-operation and the reason for failure. In Group
II, the minimum follow-up for each study was compared with the standard
minimum follow-up.Aims

The purpose of this study is to determine if higher volume hospitals
have lower costs in revision hip and knee arthroplasty. We questioned the Centres for Medicare and Medicaid Services
(CMS) Inpatient Charge Data and identified 789 hospitals performing
a total of 29 580 revision arthroplasties in 2014. Centres were
dichotomised into high-volume (performing over 50 revision cases
per year) and low-volume. Mean total hospital-specific charges and
inpatient payments were obtained from the database and stratified
based on Diagnosis Related Group (DRG) codes. Patient satisfaction
scores were obtained from the multiyear CMS Hospital Compare database.Aims

The aim of this study was to describe the epidemiology of closed
isolated fractures of the femoral shaft in children, and to compare
the treatment and length of stay (LOS) between major trauma centres
(MTCs) and trauma units (TUs) in England. National data were obtained from the Trauma and Audit Research
Network for all isolated, closed fractures of the femoral shaft
in children from birth to 15 years of age, between 2012 and 2015.
Age, gender, the season in which the fracture occurred, non-accidental
injury, the mechanism of injury, hospital trauma status, LOS and
type of treatment were recorded.Aims
