The aim of this consensus was to develop a definition of post-operative
fibrosis of the knee. An international panel of experts took part in a formal consensus
process composed of a discussion phase and three Delphi rounds.Aims
Patients and Methods
This study compared the quality of reduction
and complication rate when using a standard ilioinguinal approach and
the new pararectus approach when treating acetabular fractures surgically.
All acetabular fractures that underwent fixation using either approach
between February 2005 and September 2014 were retrospectively reviewed
and the demographics of the patients, the surgical details and complications
were recorded. A total of 100 patients (69 men, 31 women; mean age 57 years,
18 to 93) who were consecutively treated were included for analysis.
The quality of reduction was assessed using standardised measurement
of the gaps and steps in the articular surface on pre- and post-operative
CT-scans. There were no significant differences in the demographics of
the patients, the surgical details or the complications between
the two approaches. A significantly better reduction of the gap,
however, was achieved with the pararectus approach (axial: p = 0.025,
coronal: p = 0.013, sagittal: p = 0.001). These data suggest that the pararectus approach is at least equal
to, or in the case of reduction of the articular gap, superior to
the ilioinguinal approach. This approach allows direct buttressing of the dome of the acetabulum
and the quadrilateral plate, which is particularly favourable in
geriatric fracture patterns. Cite this article:
This paper aims to provide evidence-based guidance for the general orthopaedic surgeon faced with the presentation of a potential soft tissue sarcoma in an extremity.
Because there have been no standard methods to determine pre-operatively
the thickness of resection of the proximal tibia in unicompartmental
knee arthroplasty (UKA), information about the relationship between
the change of limb alignment and the joint line elevation would
be useful for pre-operative planning. The purpose of this study
was to clarify the correlation between the change of limb alignment
and the change of joint line height at the medial compartment after
UKA. A consecutive series of 42 medial UKAs was reviewed retrospectively.
These patients were assessed radiographically both pre- and post-operatively
with standing anteroposterior radiographs. The thickness of bone
resection at the proximal tibia and the distal femur was measured
radiographically. The relationship between the change of femorotibial
angle (δFTA) and the change of joint line height, was analysed.Objectives

Rib fracture fixation by orthopaedic and cardiothoracic surgeons has become increasingly popular for the treatment of chest injuries in trauma. The literature, though mainly limited to Level II and III evidence, shows favourable results for operative fixation. In this paper we review the literature and discuss the indications for rib fracture fixation, surgical approaches, choice of implants and the future direction for management. With the advent of NICE guidance and new British Orthopaedic Association Standards for Trauma (BOAST) guidelines in production, the management of rib fractures is going to become more and more commonplace.
Neuropathic changes in the foot are common with
a prevalence of approximately 1%. The diagnosis of neuropathic arthropathy
is often delayed in diabetic patients with harmful consequences
including amputation. The appropriate diagnosis and treatment can
avoid an extensive programme of treatment with significant morbidity
for the patient, high costs and delayed surgery. The pathogenesis
of a Charcot foot involves repetitive micro-trauma in a foot with impaired
sensation and neurovascular changes caused by pathological innervation
of the blood vessels. In most cases, changes are due to a combination
of both pathophysiological factors. The Charcot foot is triggered
by a combination of mechanical, vascular and biological factors
which can lead to late diagnosis and incorrect treatment and eventually
to destruction of the foot. This review aims to raise awareness of the diagnosis of the Charcot
foot (diabetic neuropathic osteoarthropathy and the differential
diagnosis, erysipelas, peripheral arterial occlusive disease) and
describe the ways in which the diagnosis may be made. The clinical
diagnostic pathways based on different classifications are presented. Cite this article:
A successful outcome following treatment of nonunion requires the correct identification of all of the underlying cause(s) and addressing them appropriately. The aim of this study was to assess the distribution and frequency of causative factors in a consecutive cohort of nonunion patients in order to optimise the management strategy for individual patients presenting with nonunion. Causes of the nonunion were divided into four categories: mechanical; infection; dead bone with a gap; and host. Prospective and retrospective data of 100 consecutive patients who had undergone surgery for long bone fracture nonunion were analysed.Objectives

The purpose of this study was to compare the joint space width between one-leg and both-legs standing radiographs in order to diagnose a primary osteoarthritis of the knee. Digital radiographs of 100 medial osteoarthritic knees in 50 patients were performed. The patients had undergone one-leg standing anteroposterior (AP) views by standing on the affected leg while a both-legs standing AP view was undertaken while standing on both legs. The severity of the osteoarthritis was evaluated using the joint space width and Kellgren-Lawrence (KL) radiographic classification. The Objectives

We report our experience of performing an elbow
hemiarthroplasty in the treatment of comminuted distal humeral fractures
in the elderly patients. A cohort of 42 patients (three men and 39 women, mean age 72;
56 to 84) were reviewed at a mean of 34.3 months (24 to 61) after
surgery. Functional outcome was measured with the Mayo Elbow Performance
Score (MEPS) and range of movement. The disabilities of the arm,
shoulder and hand questionnaire (DASH) was used as a patient rated
evaluation. Complications and ulnar nerve function were recorded.
Plain radiographs were obtained to assess prosthetic loosening,
olecranon wear and heterotopic bone formation. The mean extension deficit was 23.5° (0° to 60°) and mean flexion
was 126.8° (90° to 145°) giving a mean arc of 105.5° (60° to 145°).
The mean MEPS was 90 (50 to 100) and a mean DASH score of 20 (0
to 63). Four patients had additional surgery for limited range of
movement and one for partial instability. One elbow was revised
due to loosening, two patients had sensory ulnar nerve symptoms,
and radiographic signs of mild olecranon wear was noted in five
patients. Elbow hemiarthroplasty for comminuted intra-articular distal
humeral fractures produces reliable medium-term results with functional
outcome and complication rates, comparable with open reduction and
internal fixation and total elbow arthroplasty. Cite this article:
Periprosthetic fracture (PF) after primary total hip arthroplasty
(THA) is an uncommon but potentially devastating complication. This
study aims to investigate the influence of cemented stem designs
on the risk of needing a revision for a PF. We analysed data on 257 202 primary THAs with cemented stems
and 390 linked first revisions for PF recorded in the National Joint
Registry (NJR) of England, Wales and Northern Ireland to determine
if a cemented femoral stem brand was associated with the risk of
having revision for a PF after primary THA. All cemented femoral
stem brands with more than 10 000 primary operations recorded in
the NJR were identified. The four most commonly used cemented femoral
stems were the Exeter V40 (n = 146 409), CPT (n = 24 300), C-Stem
(n = 15 113) and Charnley (n = 20 182). We compared the revision risk ratios due to PF amongst the stems
using a Poisson regression model adjusting for patient factors.
Compared with the Exeter V40, the age, gender and ASA grade adjusted
revision rate ratio was 3.89 for the cemented CPT stem (95% confidence
interval (CI) 3.07 to 4.93), 0.89 for the C-Stem (95% CI 0.57 to
1.41) and 0.41 for the Charnley stem (95% CI 0.24 to 0.70).Aims
Patients and Methods
Hip and groin injuries are common in athletes
who take part in high level sports. Adductor muscle tendon injuries represent
a small but important number of these injuries. Avulsion of the
tendons attached to the symphysis pubis has previously been described:
these can be managed both operatively and non-operatively. We describe
an uncommon variant of this injury, namely complete avulsion of
the adductor sleeve complex: this includes adductor longus, pectineus
and rectus abdominis. We go on to describe a surgical technique
which promotes a full return to the pre-injury level of sporting
activity. Over a period of ten years, 15 high-level athletes with an MRI-confirmed
acute adductor complex avulsion injury (six to 34 days old) underwent
surgical repair. The operative procedure consisted of anatomical
re-attachment of the avulsed tissues in each case and mesh reinforcement
of the posterior inguinal wall in seven patients. All underwent a
standardised rehabilitation programme, which was then individualised
to be sport-specific. One patient developed a superficial wound infection, which was
successfully treated with antibiotics. Of the 15 patients, four
complained of transient local numbness which resolved in all cases.
All patients (including seven elite athletes) returned to their
previous level of participation in sport. Cite this article:
The goals of this study were to define the risk factors, nature,
chronology, and treatment strategies adopted for periprosthetic
femoral fractures in 32 644 primary total hip arthroplasties (THAs). There were 564 intra-operative fractures (1.7%); 529 during uncemented
stem placement (3.0%) and 35 during cemented stem placement (0.23%).
Intra-operative fractures were more common in females and patients
over 65 years (p <
0.001). The majority occurred during placement
of the femoral component (60%), and involved the calcar (69%). There
were 557 post-operative fractures (20-year probability: 3.5%; 95%
confidence interval (CI) 3.2 to 3.9); 335 fractures after placement
of an uncemented stem (20-year probability: 7.7%; 95% CI 6.2 to
9.1) and 222 after placement of a cemented stem (20-year probability:
2.1%; 95% CI 1.8 to 2.5). The probability of a post-operative fracture
within 30 days after an uncemented stem was ten times higher than
a cemented stem. The most common post-operative fracture type was
a Vancouver AG (32%; n = 135), with 67% occurring after
a fall. In all, 36% (n = 152) were treated with revision arthroplasty. Aim and Methods
Results
The objective of this study was to perform a meta-analysis of all randomised controlled trials (RCTs) comparing surgical and non-surgical management of fractures of the proximal humerus, and to determine whether further analyses based on complexity of fracture, or the type of surgical intervention, produced disparate findings on patient outcomes. A systematic review of the literature was performed identifying all RCTs that compared surgical and non-surgical management of fractures of the proximal humerus. Meta-analysis of clinical outcomes was performed where possible. Subgroup analysis based on the type of fracture, and a sensitivity analysis based on the type of surgical intervention, were also performed.Objectives

We present the clinical and radiographic outcome of 81 children
with Gartland type I to III supracondylar humeral fractures at a
minimum follow-up of ten years (mean 12.1 years; 10.3 to 16.1) following
injury. The clinical and functional outcomes are compared with normal
age- and gender-matched individuals. The population-based study
setting was first identified from the institutional registries;
the rate of participation was 76%. Controls were randomly selected
from Finnish National Population Registry.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 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

and one year post-operatively.Aims
Patients and Methods
Throughout the 20th Century, it has been postulated that the knee moves on the basis of a four-bar link mechanism composed of the cruciate ligaments, the femur and the tibia. As a consequence, the femur has been thought to roll back with flexion, and total knee arthroplasty (TKA) prostheses have been designed on this basis. Recent work, however, has proposed that at a position of between 0° and 120° the medial femoral condyle does not move anteroposteriorly whereas the lateral femoral condyle tends, but is not obliged, to roll back – a combination of movements which equates to tibial internal/ femoral external rotation with flexion. The aim of this paper was to assess if the articular geometry of the GMK Sphere TKA could recreate the natural knee movements The pattern of knee movement was studied in 15 patients (six male: nine female; one male with bilateral TKAs) with 16 GMK Sphere implants, at a mean age of 66 years (53 to 76) with a mean BMI of 30 kg/m2 (20 to 35). The motions of all 16 knees were observed using pulsed fluoroscopy during a number of weight-bearing and non-weight-bearing static and dynamic activities.Objectives
