A failed total ankle arthroplasty (TAA) is often associated with
much bone loss. As an alternative to arthrodesis, the surgeon may
consider a custom-made talar component to compensate for the bone
loss. Our aim in this study was to assess the functional and radiological
outcome after the use of such a component at mid- to long-term follow-up. A total of 12 patients (five women and seven men, mean age 53
years; 36 to77) with a failed TAA and a large talar defect underwent
a revision procedure using a custom-made talar component. The design
of the custom-made components was based on CT scans and standard
radiographs, when compared with the contralateral ankle. After the
anterior talocalcaneal joint was fused, the talar component was
introduced and fixed to the body of the calcaneum.Aims
Patients and Methods
Our aim was to prepare a systematic review and meta-analysis
to compare the outcomes of cemented and cementless hemiarthroplasty
of the hip, in elderly patients with a fracture of the femoral neck,
to investigate the mortality, complications, length of stay in hospital,
blood loss, operating time and functional results. A systematic review and meta-analysis was conducted following
the Preferred Reporting Items for Systematic Reviews and Meta-Analyses
guidelines on randomised controlled trials (RCTs), studying current
generation designs of stem only. The synthesis of results was done
of pooled data, with a fixed effects or random effects model, based on
heterogeneity.Aims
Materials and Methods
Failed internal fixation of a fracture of the
proximal humerus produces many challenges with limited surgical options.
The aim of this study was to evaluate the clinical outcomes after
the use of a reverse shoulder arthroplasty under these circumstances.
Between 2007 and 2012, 19 patients (15 women and four men, mean
age 66 years; 52 to 82) with failed internal fixation after a proximal
humeral fracture, underwent implant removal and reverse shoulder arthroplasty
(RSA). The mean follow-up was 36 months (25 to 60). The mean American
Shoulder and Elbow Score improved from 27.8 to 50.1 (p = 0.019).
The mean Simple Shoulder Test score improved from 0.7 to 3.2 (p
= 0.020), and the mean visual analogue scale for pain improved from
6.8 to 4.3 (p = 0.012). Mean forward flexion improved from 58.7°
to 101.1° (p <
0.001), mean abduction from 58.7° to 89.1° (p
= 0.012), mean external rotation from 10.7° to 23.1° (p = 0.043)
and mean internal rotation from buttocks to L4 (p = 0.034). A major
complication was recorded in five patients (26%) (one intra-operative
fracture, loosening of the humeral component in two and two peri-prosthetic
fractures). A total of 15 patients (79%) rated their outcome as
excellent or good, one (5%) as satisfactory, and three (16%) as
unsatisfactory. An improvement in outcomes and pain can be expected when performing
a RSA as a salvage procedure after failed internal fixation of a
fracture of the proximal humerus. Patients should be cautioned about
the possibility for major complications following this technically
demanding procedure. Cite this article:
We determined the efficacy of a devitalised autograft
(n = 13) and allograft (n = 16) cortical strut bone graft combined
with long-stem endoprosthetic reconstruction in the treatment of
massive tumours of the lower limb. A total of 29 patients (18 men:11
women, mean age 20.1 years (12 to 45) with a ratio of length of
resection to that of the whole prosthesis of >
50% were treated
between May 2003 and May 2012. The mean follow-up was 47 months
(15 to 132). The stem of the prosthesis was introduced through bone
graft struts filled with cement, then cemented into the residual
bone. Bone healing was achieved in 23 patients (86%). The mean Musculoskeletal
Tumour Society functional score was 85% (57 to 97). The five-year
survival rate of the endoprostheses was 81% (95% confidence intervals
67.3 to 92.3). The mean length of devitalised autografts and allografts
was 8.6 cm (5 to 15), which increased the ratio of the the length
of the stem of the prosthesis to that of the whole length of the
prosthesis from a theoretical 35% to an actual 55%. Cortical strut bone grafting and long-stem endoprosthetic reconstruction
is an option for treating massive segmental defects following resection
of a tumour in the lower limb. Patients can regain good function
with a low incidence of aseptic loosening. The strut graft and the
residual bone together serve as a satisfactory bony environment
for a revision prosthesis, if required, once union is achieved. Cite this article:
Previous classification systems of failure of
limb salvage focused primarily on endoprosthetic failures and lacked sufficient
depth for the effective study of the causes of failure. In order
to address these inadequacies, the International Society of Limb
Salvage (ISOLS) formed a committee to recommend revisions of the
previous systems. The purpose of this study was to report on their
recommendations. The modifications were prepared using an earlier,
evidence-based model with subclassification based on the existing
medical literature. Subclassification for all five primary types
of failure of limb salvage following endoprosthetic reconstruction
were formulated and a complementary system was derived for the failure
of biological reconstruction. An additional classification of failure
in paediatric patients was also described. Limb salvage surgery presents a complex array of potential mechanisms
of failure, and a complete and precise classification of types of
failure is required. Earlier classification systems lacked specificity,
and the evidence-based system outlined here is designed to correct
these weaknesses and to provide a means of reporting failures of
limb salvage in order to allow the interpretation of outcome following
reconstructive surgery. Cite this article:
Rates of mortality as high as 25% to 30% have been described
following fractures of the odontoid in the elderly population. The
aim of this study was to examine whether easily identifiable variables
present on admission are associated with mortality. A consecutive series of 83 elderly patients with a fracture of
the odontoid following a low-impact injury was identified retrospectively.
Data that were collected included demographics, past medical history
and the results of blood tests on admission. Radiological investigations
were used to assess the Anderson and D’Alonzo classification and
displacement of the fracture. The mean age was 82.9 years (65 to
101). Most patients (66; 79.5%) had a type 2 fracture. An associated
neurological deficit was present in 11 (13.3%). All were treated
conservatively; 80 (96.4%) with a hard collar and three (3.6%) with
halo vest immobilisation.Aims
Patients and Methods
The last decade has seen a considerable increase
in the use of in total ankle arthroplasty (TAA) to treat patients
with end-stage arthritis of the ankle. However, the longevity of
the implants is still far from that of total knee and hip arthroplasties. The aim of this review is to outline a diagnostic and treatment
algorithm for the painful TAA to be used when considering revision
surgery. Cite this article:
Resection of a primary sarcoma of the diaphysis
of a long bone creates a large defect. The biological options for reconstruction
include the use of a vascularised and non-vascularised fibular autograft. The purpose of the present study was to compare these methods
of reconstruction. Between 1985 and 2007, 53 patients (26 male and 27 female) underwent
biological reconstruction of a diaphyseal defect after resection
of a primary sarcoma. Their mean age was 20.7 years (3.6 to 62.4).
Of these, 26 (49 %) had a vascularised and 27 (51 %) a non-vascularised
fibular autograft. Either method could have been used for any patient in
the study. The mean follow-up was 52 months (12 to 259). Oncological,
surgical and functional outcome were evaluated. Kaplan–Meier analysis
was performed for graft survival with major complication as the
end point. At final follow-up, eight patients had died of disease. Primary
union was achieved in 40 patients (75%); 22 (42%) with a vascularised
fibular autograft and 18 (34%) a non-vascularised (p = 0.167). A
total of 32 patients (60%) required revision surgery. Kaplan–Meier
analysis revealed a mean survival without complication of 36 months
(0.06 to 107.3, Both groups seem to be reliable biological methods of reconstructing
a diaphyseal bone defect. Vascularised autografts require more revisions
mainly due to problems with wound healing in distal sites of tumour,
such as the foot. Cite this article:
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:
A possible solution for the management of proximal femoral bone
loss is a modular femoral endoprosthesis (EPR). Although the outcome
of EPRs in tumour surgery has been well described, the outcome of
their use in revision hip surgery has received less attention. The
aim of this study was to describe the outcome of using EPR for non-neoplastic
indications. A retrospective review of 79 patients who underwent 80 EPRs for
non-neoplastic indications was performed, including the rates of
complication and survival and the mean Oxford Hip Scores (OHS),
at a mean of five years post-operatively. The mean age at the time
of surgery was 69 years (28 to 93) and the mean number of previous operations
on the hip was 2.4 (0 to 17). The most common indications for EPR
implantation were periprosthetic joint infection (PJI) (n = 40),
periprosthetic fracture (n = 12) and failed osteosynthesis of a
proximal femoral fracture or complex trauma (n = 11).Objectives
Methods
The optimal management of intracapsular fractures of the femoral
neck in independently mobile patients remains open to debate. Successful
fixation obviates the limitations of arthroplasty for this group
of patients. However, with fixation failure rates as high as 30%,
the outcome of revision surgery to salvage total hip arthroplasty
(THA) must be considered. We carried out a systematic review to
compare the outcomes of salvage THA and primary THA for intracapsular
fractures of the femoral neck. We performed a Preferred Reporting Items for Systematic Reviews
and Meta-Analysis (PRISMA) compliant systematic review, using the
PubMed, EMBASE and Cochrane libraries databases. A meta-analysis
was performed where possible, and a narrative synthesis when a meta-analysis
was not possible.Aims
Patients and Methods
The continual cycle of bone formation and resorption
is carried out by osteoblasts, osteocytes, and osteoclasts under
the direction of the bone-signaling pathway. In certain situations
the host cycle of bone repair is insufficient and requires the assistance
of bone grafts and their substitutes. The fundamental properties
of a bone graft are osteoconduction, osteoinduction, osteogenesis,
and structural support. Options for bone grafting include autogenous
and allograft bone and the various isolated or combined substitutes
of calcium sulphate, calcium phosphate, tricalcium phosphate, and
coralline hydroxyapatite. Not all bone grafts will have the same
properties. As a result, understanding the requirements of the clinical
situation and specific properties of the various types of bone grafts
is necessary to identify the ideal graft. We present a review of
the bone repair process and properties of bone grafts and their
substitutes to help guide the clinician in the decision making process. Cite this article:
Primary total knee arthroplasty (TKA) is a reliable
procedure with reproducible long-term results. Nevertheless, there
are conditions related to the type of patient or local conditions
of the knee that can make it a difficult procedure. The most common
scenarios that make it difficult are discussed in this review. These
include patients with many previous operations and incisions, and
those with severe coronal deformities, genu recurvatum, a stiff knee,
extra-articular deformities and those who have previously undergone
osteotomy around the knee and those with chronic dislocation of
the patella. Each condition is analysed according to the characteristics of
the patient, the pre-operative planning and the reported outcomes. When approaching the difficult primary TKA surgeons should use
a systematic approach, which begins with the review of the existing
literature for each specific clinical situation. Cite this article:

A total of 56 male patients with a displaced
intracapsular fracture of the hip and a mean age of 81 years (62
to 94), were randomised to be treated with either a cemented hemiarthroplasty
(the Exeter Trauma Stem) or reduction and internal fixation using
the Targon Femoral Plate. All surviving patients were reviewed one
year after the injury, at which time restoration of function and
pain in the hip was assessed. There was no statistically significant
difference in mortality between the two groups (7/26; 26.9% for
hemiarthroplasty These results indicate that cemented hemiarthroplasty gives better
results than internal fixation in elderly men with a displaced intracapsular
fracture of the hip. Cite this article:
Smoking is associated with post-operative complications but smokers
often under-report the amount they smoke. Our objective was to determine
whether a urine dipstick test could be used as a substitute for
quantitative cotinine assays to determine smoking status in patients. Between September 2013 and July 2014 we conducted a prospective
cohort study in which 127 consecutive patients undergoing a planned
foot and ankle arthrodesis or osteotomy were included. Patients
self-reported their smoking status and were classified as: ‘never
smoked’ (61 patients), ‘ex-smoker’ (46 patients), or ‘current smoker’ (20
patients). Urine samples were analysed with cotinine assays and
cotinine dipstick tests.Aims
Patients and Methods
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:
