Conventional methods of treating ankle fractures
in the elderly are associated with high rates of complication. We describe
the results of treating these injuries in 48 frail elderly patients
with a long calcaneotalotibial nail. The mean age of the group was 82 years (61 to 96) and 41 (85%)
were women. All were frail, with multiple medical comorbidities
and their mean American Society of Anaesthesiologists score was
3 (3 to 4). None could walk independently before their operation.
All the fractures were displaced and unstable; the majority (94%,
45 of 48) were low-energy injuries and 40% (19 of 48) were open. The overall mortality at six months was 35%. Of the surviving
patients, 90% returned to their pre-injury level of function. The
mean pre- and post-operative Olerud and Molander questionnaire scores
were 62 and 57 respectively. Complications included superficial
infection (4%, two of 48); deep infection (2%, one of 48); a broken
or loose distal locking screw (6%, three of 48); valgus malunion
(4%, two of 48); and one below-knee amputation following an unsuccessful
vascular operation. There were no cases of nonunion, nail breakage
or peri-prosthetic fracture. A calcaneotalotibial nail is an excellent device for treating
an unstable fracture of the ankle in the frail elderly patient.
It allows the patient to mobilise immediately and minimises the
risk of bone or wound problems. A long nail which crosses the isthmus
of the tibia avoids the risk of peri-prosthetic fracture associated
with shorter devices. Cite this article:
Haematomas, drainage, and other non-infectious
wound complications following total knee replacement (TKR) have
been associated with long-term sequelae, in particular, deep infection.
However, the impact of these wound complications on clinical outcome
is unknown. This study compares results in 15 patients re-admitted
for wound complications within 90 days of TKR to 30 matched patients
who underwent uncomplicated total knee replacements. Patients with
wound complications had a mean age of 66 years (49 to 83) and mean
body mass index (BMI) of 37 (21 to 54), both similar to that of
patients without complications (mean age 65 years and mean BMI 35). Those
with complications had lower mean Knee Society function scores (46

Peri-acetabular tumour resections and their subsequent
reconstruction are among the most challenging procedures in orthopaedic
oncology. Despite the fact that a number of different pelvic endoprostheses
have been introduced, rates of complication remain high and long-term
results are mostly lacking. In this retrospective study, we aimed to evaluate the outcome
of reconstructing a peri-acetabular defect with a pedestal cup endoprosthesis
after a type 2 or type 2/3 internal hemipelvectomy. A total of 19 patients (11M:8F) with a mean age of 48 years (14
to 72) were included, most of whom had been treated for a primary
bone tumour (n = 16) between 2003 and 2009. After a mean follow-up
of 39 months (28 days to 8.7 years) seven patients had died. After
a mean follow-up of 7.9 years (4.3 to 10.5), 12 patients were alive,
of whom 11 were disease-free. Complications occurred in 15 patients.
Three had recurrent dislocations and three experienced aseptic loosening.
There were no mechanical failures. Infection occurred in nine patients,
six of whom required removal of the prosthesis. Two patients underwent
hindquarter amputation for local recurrence. The implant survival rate at five years was 50% for all reasons,
and 61% for non-oncological reasons. The mean Musculoskeletal Tumor
Society score at final follow-up was 49% (13 to 87). Based on these poor results, we advise caution if using the pedestal
cup for reconstruction of a peri-acetabular tumour resection. Cite this article:

randomised controlled trial (RCT) to assess the clinical and cost
effectiveness of arthroscopic and open surgery in the management
of rotator cuff tears. This trial began in 2007 and was modified
in 2010, with the removal of a non-operative arm due to high rates
of early crossover to surgery. Cite this article:

Patient-centred medicine is an approach to medical care that emphasises the patient experience. Treatment outcome measures reflect this experience, and outcomes are measured by obtaining patient feedback. Central to this type of care is the patient-physician relationship. Communication, physician empathy, and shared decision making are key components of this relationship. Patient-centred care is correlated with better patient outcomes across medical specialties and higher patient perceived quality of care. Payors are now using patient-centred quality measures in their physician reimbursement schedules.
To determine the morbidity and mortality outcomes of patients
presenting with a fractured neck of femur in an Australian context.
Peri-operative variables related to unfavourable outcomes were identified
to allow planning of intervention strategies for improving peri-operative
care. We performed a retrospective observational study of 185 consecutive
adult patients admitted to an Australian metropolitan teaching hospital
with fractured neck of femur between 2009 and 2010. The main outcome
measures were 30-day and one-year mortality rates, major complications
and factors influencing mortality. Objectives

The National Institute for Health and Clinical
Excellence (NICE) has thus far relied on historical data and predominantly
industry-sponsored trials to provide evidence for venous thromboembolic
(VTE) prophylaxis in joint replacement patients. We argue that the
NICE guidelines may be reliant on assumptions that are in need of
revision. Following the publication of large scale, independent
observational studies showing little difference between low-molecular-weight
heparins and aspirin, and recent changes to the guidance provided
by other international bodies, should NICE reconsider their recommendations? Cite this article:
We compared the clinical, radiological and quality-of-life
outcomes between hybrid and total pedicle screw instrumentation
in patients undergoing surgery for neuromuscular scoliosis. Total pedicle screw instrumentation provided shorter operating
times, less blood loss and better correction of the major curve
compared with hybrid constructs in patients undergoing surgery for
neuromuscular scoliosis.
We evaluated the clinical results and complications
after extra-articular resection of the distal femur and/or proximal
tibia and reconstruction with a tumour endoprosthesis (MUTARS) in
59 patients (mean age 33 years (11 to 74)) with malignant bone or
soft-tissue tumours. According to a Kaplan–Meier analysis, limb
survival was 76% (95% confidence interval (CI) 64.1 to 88.5) after
a mean follow-up of 4.7 years (one month to 17 years). Peri-prosthetic infection
was the most common indication for subsequent amputation (eight
patients). Survival of the prosthesis without revision was 48% (95%
CI 34.8 to 62.0) at two years and 25% (95% CI 11.1 to 39.9) at five years
post-operatively. Failure of the prosthesis was due to deep infection
in 22 patients (37%), aseptic loosening in ten patients (17%), and
peri-prosthetic fracture in six patients (10%). Wear of the bearings
made a minor revision necessary in 12 patients (20%). The mean Musculoskeletal
Tumor Society score was 23 (10 to 29). An extensor lag >
10° was
noted in ten patients (17%). These results suggest that limb salvage after extra-articular
resection with a tumour prosthesis can achieve good functional results
in most patients, although the rates of complications and subsequent
amputation are higher than in patients treated with intra-articular
resection. Cite this article:
To date, all surgical techniques used for reconstruction
of the pelvic ring following supra-acetabular tumour resection produce
high complication rates. We evaluated the clinical, oncological
and functional outcomes of a cohort of 35 patients (15 men and 20
women), including 21 Ewing’s sarcomas, six chondrosarcomas, three sarcomas
not otherwise specified, one osteosarcoma, two osseous malignant
fibrous histiocytomas, one synovial cell sarcoma and one metastasis.
The mean age of the patients was 31 years (8 to 79) and the latest
follow-up was carried out at a mean of 46 months (1.9 to 139.5)
post-operatively. We undertook a functional reconstruction of the pelvic ring using
polyaxial screws and titanium rods. In 31 patients (89%) the construct
was encased in antibiotic-impregnated polymethylmethacrylate. Preservation
of the extremities was possible for all patients. The survival rate
at three years was 93.9% (95% confidence interval (CI) 77.9 to 98.4),
at five years it was 82.4% (95% CI 57.6 to 93.4). For the 21 patients
with Ewing’s sarcoma it was 95.2% (95% CI 70.7 to 99.3) and 81.5%
(95% CI 52.0 to 93.8), respectively. Wound healing problems were
observed in eight patients, deep infection in five and clinically
asymptomatic breakage of the screws in six. The five-year implant survival
was 93.3% (95% CI 57.8 to 95.7). Patients were mobilised at a mean
of 3.5 weeks (1 to 7) post-operatively. A post-operative neurological
defect occurred in 12 patients. The mean Musculoskeletal Tumor Society
score at last available follow-up was 21.2 (10 to 27). This reconstruction technique is characterised by simple and
oncologically appropriate applicability, achieving high primary
stability that allows early mobilisation, good functional results
and relatively low complication rates. Cite this article:

Ankle Roundup360 looks at: ankle arthrodesis in young active patients; the Bologna-Oxford total ankle replacements; significant failure and revision rates for total ankle arthroplasty; surgical treatment of Achilles tendon rupture; selective plantar fascia release; whether removal of metalwork can resolve foot pain; allografting of osteochondral lesions; distracting from osteoarthritis; and ultrasound-guided minimally invasive surgery.
Post-operative complications after total hip
or knee replacement can delay recovery, prolong hospitalisation, increase
rates of re-admission and, in the most severe cases, lead to long-term
disability or even death. In this analysis of pooled data from four
large, randomised, phase III clinical trials that compared the oral,
direct Factor Xa inhibitor rivaroxaban with subcutaneous enoxaparin
for the prevention of venous thromboembolism after total hip or
knee replacement (n = 12 729), the incidence of complications, including
bleeding and adverse events related to surgery (such as wound infection,
wound dehiscence and haemarthrosis) are reported. Interventions
and procedures relating to surgery are also compared between the
groups. Bleeding events, including excessive wound haematoma and
surgical-site bleeding, occurred at similar rates in the rivaroxaban
and enoxaparin groups. Over the total study duration, adverse surgical
events occurred at a similar rate in the rivaroxaban group compared
with the enoxaparin group after total knee replacement (2.26% This analysis shows that the incidence of adverse surgical events
with rivaroxaban was similar to enoxaparin.
Patient safety is a critical issue in elective
total joint replacement surgery. Identifying risk factors that might
predict complications and intensive care unit (ICU) admission proves instrumental
in reducing morbidity and mortality. The institution’s experience
with risk stratification and pre-operative ICU triage has resulted
in a reduction in unplanned ICU admissions and post-operative complications
after total hip replacement. The application of the prediction tools
to total knee replacement has proven less robust so far. This work
also reviews areas for future research in patient safety and cost
containment. Cite this article:
We present the extended follow-up (≥ 20 years)
of a series of fully hydroxyapatite-coated femoral components used in
72 primary total hip replacements (THRs). Earlier results of this
cohort have been previously published. All procedures were performed
between 1986 and 1991. The series involved 45 women and 15 men with
12 bilateral procedures. Their mean age at the time of surgery was
60 years (46 to 80) and the mean duration of follow-up was 22.5
years (20 to 25). At final follow-up, the mean Merle d’Aubigné and
Postel hip scores were 5.5 (4.5 to 6), 3.8 (3.5 to 5) and 3.3 (3.0
to 5.0) for pain, mobility and function, respectively. Of the patients
92% were very satisfied at the time of final follow-up. There were seven revisions: six of the acetabular component for
aseptic loosening and one of both the stem and the acetabular component
for loosening due to deep infection. The survival of this prosthesis
at 22.5 years with revision for any reason as the endpoint was 91.7%
(95% confidence interval (CI) 84 to 99). Survival with aseptic loosening
of the stem as the endpoint was 100% (95% CI 90 to 100). This prosthesis provides pain relief in the long term. Survival
of this component is comparable to the best results for primary
THR with any means of fixation. Cite this article:
This is a prospective randomised study comparing
the clinical and radiological outcomes of uni- and bipedicular balloon
kyphoplasty for the treatment of osteoporotic vertebral compression
fractures. A total of 44 patients were randomised to undergo either
uni- or bipedicular balloon kyphoplasty. Self-reported clinical
assessment using the Oswestry Disability Index, the Roland-Morris
Disability questionnaire and a visual analogue score for pain was undertaken
pre-operatively, and at three and twelve months post-operatively.
The vertebral height and kyphotic angle were measured from pre-
and post-operative radiographs. Total operating time and the incidence
of cement leakage was recorded for each group. Both uni- and bipedicular kyphoplasty groups showed significant
within-group improvements in all clinical outcomes at three months
and twelve months after surgery. However, there were no significant
differences between the groups in all clinical and radiological
outcomes. Operating time was longer in the bipedicular group (p <
0.001). The incidence of cement leakage was not significantly different
in the two groups (p = 0.09). A unipedicular technique yielded similar clinical and radiological
outcomes as bipedicular balloon kyphoplasty, while reducing the
length of the operation. We therefore encourage the use of a unipedicular
approach as the preferred surgical technique for the treatment of
osteoporotic vertebral compression fractures. 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
