Supracondylar humeral fractures are common in
children, but there are no classification systems or radiological parameters
that predict the likelihood of having to perform an open reduction.
In a retrospective case–control study we evaluated the use of the
medial spike angle and fracture tip–skin distance to predict the
mode of reduction (closed or open) and the operating time in fractures
with posterolateral displacement. A total of 21 patients (4.35%) with
a small medial spike angle (<
45°) were identified from a total
of 494 patients, and 42 patients with a medial spike angle of >
45° were randomly selected as controls. The medial spike group had
significantly smaller fracture tip–skin distances (p <
0.001),
longer operating times (p = 0.004) and more complications (p = 0.033)
than the control group. There was no significant difference in the
mode of reduction and a composite outcome measure. After adjustments
for age and gender, only fracture tip–skin distance remained significantly
associated with the operating time (β = -0.724, p = 0.042) and composite
outcome (OR 0.863 (95% confidence interval 0.746 to 0.998); p = 0.048). Paediatric orthopaedic surgeons should have a lower threshold
for open reduction when treating patients with a small medial spike
angle and a small fracture tip–skin distance. Cite this article:

The sternoclavicular joint (SCJ) is a pivotal
articulation in the linked system of the upper limb girdle, providing
load-bearing in compression while resisting displacement in tension
or distraction at the manubrium sterni. The SCJ and acromioclavicular
joint (ACJ) both have a small surface area of contact protected
by an intra-articular fibrocartilaginous disc and are supported
by strong extrinsic and intrinsic capsular ligaments. The function
of load-sharing in the upper limb by bulky periscapular and thoracobrachial
muscles is extremely important to the longevity of both joints.
Ligamentous and capsular laxity changes with age, exposing both
joints to greater strain, which may explain the rising incidence
of arthritis in both with age. The incidence of arthritis in the
SCJ is less than that in the ACJ, suggesting that the extrinsic
ligaments of the SCJ provide greater stability than the coracoclavicular
ligaments of the ACJ. Instability of the SCJ is rare and can be difficult to distinguish
from medial clavicular physeal or metaphyseal fracture-separation:
cross-sectional imaging is often required. The distinction is important
because the treatment options and outcomes of treatment are dissimilar,
whereas the treatment and outcomes of ACJ separation and fracture
of the lateral clavicle can be similar. Proper recognition and treatment
of traumatic instability is vital as these injuries may be life-threatening.
Instability of the SCJ does not always require surgical intervention.
An accurate diagnosis is required before surgery can be considered,
and we recommend the use of the Stanmore instability triangle. Most
poor outcomes result from a failure to recognise the underlying
pathology. There is a natural reluctance for orthopaedic surgeons to operate
in this area owing to unfamiliarity with, and the close proximity
of, the related vascular structures, but the interposed sternohyoid
and sternothyroid muscles are rarely injured and provide a clear
boundary to the medial retroclavicular space, as well as an anatomical
barrier to unsafe intervention. This review presents current concepts of instability of the SCJ,
describes the relevant surgical anatomy, provides a framework for
diagnosis and management, including physiotherapy, and discusses
the technical challenges of operative intervention. Cite this article:
Patient specific cutting guides generated by
preoperative Magnetic Resonance Imaging (MRI) of the patient’s extremity
have been proposed as a method of improving the consistency of Total
Knee Arthroplasty (TKA) alignment and adding efficiency to the operative
procedure. The cost of this option was evaluated by quantifying the
savings from decreased operative time and instrument processing
costs compared to the additional cost of the MRI and the guide.
Coronal plane alignment was measured in an unselected consecutive
series of 200 TKAs, 100 with standard instrumentation and 100 with
custom cutting guides. While the cutting guides had significantly lower
total operative time and instrument processing time, the estimated
$322 savings was overwhelmed by the $1,500 additional cost of the
MRI and the cutting guide. All measures of coronal plane alignment
were equivalent between the two groups. The data does not currently
support the proposition that patient specific guides add value to
TKA.
The technical advances in arthroscopic surgery
of the hip, including the improved ability to manage the capsule
and gain extensile exposure, have been paralleled by a growth in
the number of conditions that can be addressed. This expanding list
includes symptomatic labral tears, chondral lesions, injuries of
the ligamentum teres, femoroacetabular impingement (FAI), capsular
laxity and instability, and various extra-articular disorders, including snapping
hip syndromes. With a careful diagnostic evaluation and technical
execution of well-indicated procedures, arthroscopic surgery of
the hip can achieve successful clinical outcomes, with predictable
improvements in function and pre-injury levels of physical activity
for many patients. This paper reviews the current position in relation to the use
of arthroscopy in the treatment of disorders of the hip. Cite this article:
The period of post-operative treatment before surgical wounds
are completely closed remains a key window, during which one can
apply new technologies that can minimise complications. One such
technology is the use of negative pressure wound therapy to manage
and accelerate healing of the closed incisional wound (incisional
NPWT). We undertook a literature review of this emerging indication
to identify evidence within orthopaedic surgery and other surgical
disciplines. Literature that supports our current understanding
of the mechanisms of action was also reviewed in detail. Objectives
Methods
We present our early experience of arthroscopic
reduction of the dislocated hip in very young infants with developmental
dysplasia of the hip (DDH). Eight dislocated hips, which had failed attempts at closed reduction,
were treated by arthroscopy of the hip in five children with a mean
age of 5.8 months (4 to 7). A two-portal technique was used, with
a medial sub-adductor portal for a 2.7 mm cannulated system with
a 70° arthroscope and an anterolateral portal for the instruments. Following
evaluation of the key intra-articular structures, the hypertrophic
ligamentum teres and acetabular pulvinar were resected, and a limited
release of the capsule was performed prior to reduction of the hip.
All hips were reduced by a single arthroscopic procedure, the reduction
being confirmed on MRI scan. None of the hips had an inverted labrum.
The greatest obstacle to reduction was a constriction of the capsule.
At a mean follow-up of 13.2 months (9 to 24), all eight hips remained
stable. Three developed avascular necrosis. The mean acetabular index
decreased from 35.5° (30° to 40°) pre-operatively to 23.3° (17°
to 28°). This study demonstrates that arthroscopic reduction is feasible
using two standardised portals. Longer follow-up studies are necessary
to evaluate the functional results.
The April 2012 Trauma Roundup360 looks at fibula-pro-tibia plating, galeazzi fractures, distal radial fractures in the over 65s, transverse sacral fractures, acute dislocation of the knee, posterior malleolar fractures, immobilising the broken scaphoid, the terrible triad, lower limb amputation after trauma, and whiplash injuries
Femoroacetabular impingement (FAI) causes pain
and chondrolabral damage via mechanical overload during movement
of the hip. It is caused by many different types of pathoanatomy,
including the cam ‘bump’, decreased head–neck offset, acetabular
retroversion, global acetabular overcoverage, prominent anterior–inferior
iliac spine, slipped capital femoral epiphysis, and the sequelae
of childhood Perthes’ disease. Both evolutionary and developmental factors may cause FAI. Prevalence
studies show that anatomic variations that cause FAI are common
in the asymptomatic population. Young athletes may be predisposed
to FAI because of the stress on the physis during development. Other
factors, including the soft tissues, may also influence symptoms and
chondrolabral damage. FAI and the resultant chondrolabral pathology are often treated
arthroscopically. Although the results are favourable, morphologies
can be complex, patient expectations are high and the surgery is
challenging. The long-term outcomes of hip arthroscopy are still
forthcoming and it is unknown if treatment of FAI will prevent arthrosis.
The outcome of an anatomical shoulder replacement
depends on an intact rotator cuff. In 1981 Grammont designed a novel
large-head reverse shoulder replacement for patients with cuff deficiency.
Such has been the success of this replacement that it has led to
a rapid expansion of the indications. We performed a systematic
review of the literature to evaluate the functional outcome of each
indication for the reverse shoulder replacement. Secondary outcome
measures of range of movement, pain scores and complication rates
are also presented.
This pilot study analysed the outcome of open The mean age of the patients was 22.9 years (18 to 28) and the
mean follow-up was 28.7 months (24 to 36). There were no statistically
significant differences in regard to age of patients, cyst size
and the follow-up periods in the two groups. The operating time
and mean length of stay of group 2 patients was significantly shorter
than group 1 patients (p <
0.001). The time to healing was similar
in the two groups. The overall success rates for groups 1 and 2 were
92.3% (12 of 13) and 100% (13 of 13), respectively, and there were
no statistically significant differences regarding radiological
healing. This pilot study suggests that endoscopic curettage and
percutaneous grafting is a simple and safe form of treatment, with
similar results to those following open treatment.
Controversy surrounds the most appropriate treatment
method for patients with a rupture of the tendo Achillis. The aim
of this study was to assess the long term rate of re-rupture following
management with a non-operative functional protocol. We report the outcome of 945 consecutive patients (949 tendons)
diagnosed with a rupture of the tendo Achillis managed between 1996
and 2008. There were 255 female and 690 male patients with a mean
age of 48.97 years (12 to 86). Delayed presentation was defined
as establishing the diagnosis and commencing treatment more than
two weeks after injury. The overall rate of re-rupture was 2.8%
(27 re-ruptures), with a rate of 2.9%
(25 re-ruptures) for those with an acute presentation and 2.7% (two
re-ruptures) for those with delayed presentation. This study of non-operative functional management of rupture
of the tendo Achillis is the largest of its kind in the literature. Our
rates of re-rupture are similar to, or better than, those published
for operative treatment. We recommend our regime for patients of
all ages and sporting demands, but it is essential that they adhere
to the protocol.
This paper describes the current views on the pathology of lesions of the tendon of the long head of biceps and their management. Their diagnosis is described and their surgical management classified, with details of the techniques employed.
Over recent years hip arthroscopic surgery has
evolved into one of the most rapidly expanding fields in orthopaedic surgery.
Complications are largely transient and incidences between 0.5%
and 6.4% have been reported. However, major complications can and
do occur. This article analyses the reported complications and makes recommendations
based on the literature review and personal experience on how to
minimise them.
The aim of this prospective randomised study
was to compare the clinical and radiological results of a cemented
all-polyethylene Ultima acetabular component with those of a cementless
porous-coated acetabular component (PFC) following total hip replacement
(THR). A total of 287 patients received either a polyethylene acetabular
component (group A) or a cobalt–chromium porous-coated component
(group B) with an identical cemented femoral component and 28 mm
cobalt-chromium head, thus making it the largest study of its type.
Patients were evaluated radiologically and clinically using the
Harris hip score (HHS). Group A comprised 183 patients (73 male,
110 female) with a mean age of
71.3 years (55 to 89). Group B comprised 104 patients (48 male,
56 female) with a mean age of 69.8 years (56 to 89). A total of
16 patients (13 in Group A, three in Group B) did not have post-operative
data for analysis. The mean follow-up in group A was 7.52 years
(0.4 to 15.0) and in Group B 7.87 years (0.5 to 14.0). At final follow-up the mean HHS was similar between groups A
and B (74.5 (25 to 100) and 78.0 (37 to 100), respectively; p =
0.068). The total number of revisions for any cause was 28, 17 of
which were in group A and 11 in group B. The ten-year survivorship
was 86.8% (95% confidence interval (CI) 78.4 to 92.1) and 89.2%
(95% CI 78.3 to 94.8) for groups A and B, respectively (log-rank
p-value = 0.938). A total of 20 cemented and two cementless acetabular
components had evidence of acetabular radiolucencies or acetabular
component migration at last follow-up (p = 0.001). These results indicate that patients with a cemented all-polyethylene
and cementless porous-coated polyethylene lined acetabular component
have similar long-term clinical outcomes.
