The management of children’s fractures has evolved
as a result of better health education, changes in lifestyle, improved
implant technology and the changing expectations of society. This
review focuses on the changes seen in paediatric fractures, including
epidemiology, the increasing problems of obesity, the mechanisms
of injury, non-accidental injuries and litigation. We also examine
the changes in the management of fractures at three specific sites:
the supracondylar humerus, femoral shaft and forearm. There has
been an increasing trend towards surgical stabilisation of these
fractures. The reasons for this are multifactorial, including societal
expectations of a perfect result and reduced hospital stay. Reduced hospital
stay is beneficial to the social, educational and psychological
needs of the child and beneficial to society as a whole, due to
reduced costs. Cite this article:
The management of open lower limb fractures in the United Kingdom
has evolved over the last ten years with the introduction of major
trauma networks (MTNs), the publication of standards of care and
the wide acceptance of a combined orthopaedic and plastic surgical approach
to management. The aims of this study were to report recent changes
in outcome of open tibial fractures following the implementation
of these changes. Data on all patients with an open tibial fracture presenting
to a major trauma centre between 2011 and 2012 were collected prospectively.
The treatment and outcomes of the 65 Gustilo Anderson Grade III
B tibial fractures were compared with historical data from the same
unit. Aims
Patients and Methods
We assessed the orientation of the acetabular
component in 1070 primary total hip arthroplasties with hard-on-soft, small
diameter bearings, aiming to determine the size and site of the
target zone that optimises outcome. Outcome measures included complications,
dislocations, revisions and ΔOHS (the difference between the Oxford
Hip Scores pre-operatively and five years post-operatively). A wide
scatter of orientation was observed (2 This study demonstrated that with traditional technology surgeons
can only reliably achieve a target zone of ±15°. As the optimal
zone to diminish the risk of dislocation is also ±15°, surgeons
should be able to achieve this. This is the first study to demonstrate
that optimal orientation of the acetabular component improves the
functional outcome. However, the target zone is small (± 5°) and
cannot, with current technology, be consistently achieved. Cite this article:
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:

The aim of this study was to present data on 11 459 patients
who underwent total hip (THA), total knee (TKA) or unicompartmental
knee arthroplasty (UKA) between November 2002 and April 2014 with
aspirin as the primary agent for pharmacological thromboprophylaxis. We analysed the incidence of deep vein thrombosis (DVT) and pulmonary
embolism (PE) then compared the 90-day all-cause mortality with
the corresponding data in the National Joint Registry for England
and Wales (NJR). Aims
Patients and Methods
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 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.

Methods
An uncemented hemispherical acetabular component
is the mainstay of acetabular revision and gives excellent long-term
results. Occasionally, the degree of acetabular bone loss means that a
hemispherical component will be unstable when sited in the correct
anatomical location or there is minimal bleeding host bone left
for biological fixation. On these occasions an alternative method
of reconstruction has to be used. A major column structural allograft has been shown to restore
the deficient bone stock to some degree, but it needs to be off-loaded
with a reconstruction cage to prevent collapse of the graft. The
use of porous metal augments is a promising method of overcoming
some of the problems associated with structural allograft. If the defect
is large, the augment needs to be protected by a cage to allow ingrowth
to occur. Cup-cage reconstruction is an effective method of treating
chronic pelvic discontinuity and large contained or uncontained
bone defects. This paper presents the indications, surgical techniques and
outcomes of various methods which use acetabular reconstruction
cages for revision total hip arthroplasty. Cite this article:

There are many guidelines that help direct the management of
patients with metal-on-metal (MOM) hip arthroplasties. We have undertaken
a study to compare the management of patients with MOM hip arthroplasties in
different countries. Six international tertiary referral orthopaedic centres were
invited to participate by organising a multi-disciplinary team (MDT)
meeting, consisting of two or more revision hip arthroplasty surgeons
and a musculoskeletal radiologist. A full clinical dataset including
history, blood tests and imaging for ten patients was sent to each
unit, for discussion and treatment planning. Differences in the
interpretation of findings, management decisions and rationale for
decisions were compared using quantitative and qualitative methods.Aims
Methods
The authors present the results of a cohort study of 60 adult
patients presenting sequentially over a period of 15 years from
1997 to 2012 to our hospital for treatment of thoracic and/or lumbar
vertebral burst fractures, but without neurological deficit. All patients were treated by early mobilisation within the limits
of pain, early bracing for patient confidence and all progress in
mobilisation was recorded on video. Initial hospital stay was one
week. Subsequent reviews were made on an outpatient basis. Aims
Method
We report the kinematic and early clinical results
of a patient- and observer-blinded randomised controlled trial in which
CT scans were used to compare potential impingement-free range of
movement (ROM) and acetabular component cover between patients treated
with either the navigated ‘femur-first’ total hip arthroplasty (THA) method
(n = 66; male/female 29/37, mean age 62.5 years; 50 to 74) or conventional
THA (n = 69; male/female 35/34, mean age 62.9 years; 50 to 75).
The Hip Osteoarthritis Outcome Score, the Harris hip score, the
Euro-Qol-5D and the Mancuso THA patient expectations score were
assessed at six weeks, six months and one year after surgery. A
total of 48 of the patients (84%) in the navigated ‘femur-first’
group and 43 (65%) in the conventional group reached all the desirable
potential ROM boundaries without prosthetic impingement for activities
of daily living (ADL) in flexion, extension, abduction, adduction
and rotation (p = 0.016). Acetabular component cover and surface
contact with the host bone were >
87% in both groups. There was
a significant difference between the navigated and the conventional
groups’ Harris hip scores six weeks after surgery (p = 0.010). There
were no significant differences with respect to any clinical outcome
at six months and one year of follow-up. The navigated ‘femur-first’
technique improves the potential ROM for ADL without prosthetic
impingement, although there was no observed clinical difference
between the two treatment groups. Cite this article:
There is conflicting evidence about the benefit
of using corticosteroid in periarticular injections for pain relief
after total knee arthroplasty (TKA). We carried out a double-blinded,
randomised controlled trial to assess the efficacy of using corticosteroid
in a periarticular injection to control pain after TKA. A total of 77 patients, 67 women and ten men, with a mean age
of 74 years (47 to 88) who were about to undergo unilateral TKA
were randomly assigned to have a periarticular injection with or
without corticosteroid. The primary outcome was post-operative pain
at rest during the first 24 hours after surgery, measured every
two hours using a visual analogue pain scale score. The cumulative
pain score was quantified using the area under the curve. The corticosteroid group had a significantly lower cumulative
pain score than the no-corticosteroid group during the first 24
hours after surgery (mean area under the curve 139, 0 to 560, and
264, 0 to 1460; p = 0.024). The rate of complications, including
surgical site infection, was not significantly different between
the two groups up to one year post-operatively. The addition of corticosteroid to the periarticular injection
significantly decreased early post-operative pain. Further studies
are needed to confirm the safety of corticosteroid in periarticular
injection.

Bactericidal levels of antibiotics are difficult
to achieve in infected total joint arthroplasty when intravenous antibiotics
or antibiotic-loaded cement spacers are used, but intra-articular
(IA) delivery of antibiotics has been effective in several studies.

The modified Smith–Petersen and Kocher–Langenbeck
approaches were used to expose the lateral cutaneous nerve of the
thigh and the femoral, obturator and sciatic nerves in order to
study the risk of injury to these structures during the dissection,
osteotomy, and acetabular reorientation stages of a Bernese peri-acetabular
osteotomy. Injury of the lateral cutaneous nerve of thigh was less likely
to occur if an osteotomy of the anterior superior iliac spine had
been carried out before exposing the hip. The obturator nerve was likely to be injured during unprotected
osteotomy of the pubis if the far cortex was penetrated by >
5 mm.
This could be avoided by inclining the osteotome 45° medially and
performing the osteotomy at least 2 cm medial to the iliopectineal
eminence. The sciatic nerve could be injured during the first and last
stages of the osteotomy if the osteotome perforated the lateral
cortex of ischium and the ilio-ischial junction by >
10 mm. The femoral nerve could be stretched or entrapped during osteotomy
of the pubis if there was significant rotational or linear displacement
of the acetabulum. Anterior or medial displacement of <
2 cm
and lateral tilt (retroversion) of <
30° were safe margins. The
combination of retroversion and anterior displacement could increase tension
on the nerve. Strict observation of anatomical details, proper handling of
the osteotomes and careful manipulation of the acetabular fragment
reduce the neurological complications of Bernese peri-acetabular
osteotomy. Cite this article:
This study aimed to determine the long-term functional,
clinical and radiological outcomes in patients with Schatzker IV
to VI fractures of the tibial plateau treated with an Ilizarov frame.
Clinical, functional and radiological assessment was carried out
at a minimum of one year post-operatively. A cohort of 105 patients
(62 men, 43 women) with a mean age of 49 years (15 to 87) and a
mean follow-up of 7.8 years (1 to 19) were reviewed. There were
18 type IV, 10 type V and 77 type VI fractures. All fractures united
with a mean time to union of 20.1 weeks (10.6 to 42.3). No patient
developed a deep infection. The median range of movement (ROM) of
the knee was 110o and the median Iowa score was 85. Our study demonstrates good long-term functional outcome with
no deep infection; spanning the knee had no detrimental effect on
the ROM or functional outcome. High-energy fractures of the tibial plateau may be treated effectively
with a fine wire Ilizarov fixator. Cite this article:
As adverse events related to metal on metal hip
arthroplasty have been better understood, there has been increased
interest in toxicity related to the high circulating levels of cobalt ions.
However, distinguishing true toxicity from benign elevations in
cobalt levels can be challenging. The purpose of this review is
to examine the use of cobalt alloys in total hip arthroplasty, to
review the methods of measuring circulating cobalt levels, to define
a level of cobalt which is considered pathological and to review
the pathophysiology, risk factors and treatment of cobalt toxicity.
To the best of our knowledge, there are 18 published cases where
cobalt metal ion toxicity has been attributed to the use of cobalt-chromium
alloys in hip arthroplasty. Of these cases, the great majority reported
systemic toxic reactions at serum cobalt levels more than 100 μg/L.
This review highlights some of the clinical features of cobalt toxicity,
with the goal that early awareness may decrease the risk factors
for the development of cobalt toxicity and/or reduce its severity. Take home message: Severe adverse events can arise from the release
of cobalt from metal-on-metal arthroplasties, and as such, orthopaedic
surgeons should not only be aware of the presenting problems, but
also have the knowledge to treat appropriately. Cite this article:
The aim of this study was to evaluate the prognostic
and therapeutic factors which influence the oncological outcome
of parosteal osteosarcoma. A total of 80 patients with a primary parosteal osteosarcoma
were included in this retrospective study. There were 51 females
and 29 males with a mean age of 29.9 years (11 to 78). The mean follow-up was 11.2 years (1 to 40). Overall survival
was 91.8% at five years and 87.8% at ten years. Local recurrence
occurred in 14 (17.5%) patients and was associated with intralesional
surgery and a large volume of tumour. On histological examination,
80% of the local recurrences were dedifferentiated high-grade tumours.
A total of 12 (14.8%) patients developed pulmonary metastases, of
whom half had either a dedifferentiated tumour or a local recurrence.
Female gender and young age were good prognostic factors. Local
recurrence was a poor prognostic factor for survival. Medullary
involvement or the use of chemotherapy had no impact on survival. The main goal in treating a parosteal osteosarcoma must be to
achieve a wide surgical margin, as inadequate margins are associated
with local recurrence. Local recurrence has a significant negative
effect on survival, as 80% of the local recurrences are high-grade
dedifferentiated tumours, and half of these patients develop metastases. The role of chemotherapy in the treatment of parosteal osteosarcoma
is not as obvious as it is in the treatment of conventional osteosarcoma.
The mainstay of treatment is wide local excision. Cite this article:
