Aims. Custom-made partial pelvis replacements (PPRs) are increasingly used in the reconstruction of large acetabular defects and have mainly been designed using a triflange approach, requiring extensive soft-tissue dissection. The monoflange design, where primary
Our rural orthopaedic service has undergone service restructure during the COVID-19 pandemic in order to sustain hip fracture care. All adult trauma care has been centralised to the Royal Shrewsbury Hospital for assessment and medical input, before transferring those requiring operative intervention to the Robert Jones and Agnes Hunt Orthopaedic Hospital. We aim to review the impact of COVID-19 on hip fracture workload and service changes upon management of hip fractures. We reviewed our prospectively maintained trust database and National Hip Fracture Database records for the months of March and April between the years 2016 and 2020. Our assessment included fracture pattern (intrascapular vs extracapsular hip fracture), treatment intervention, length of stay and mortality.Aims
Methods
We investigated patient characteristics and outcomes of Vancouver type B periprosthetic fractures treated with femoral component revision and/or osteosynthesis. The study utilized data from the Swedish Hip Arthroplasty Register (SHAR) and information from patient records. We included all primary total hip arthroplasties (THAs) performed in Sweden since 1979, and undergoing further surgery due to Vancouver type B periprosthetic femoral fracture between 2001 and 2011. The primary outcome measure was any further reoperation between 2001 and 2013. Cross-referencing with the National Patient Register was performed in two stages, in order to identify all surgical procedures not recorded on the SHAR.Aims
Patients and Methods
The paradoxical migration of the femoral neck element (FNE) superomedially against gravity, with respect to the intramedullary component of the cephalomedullary device, is a poorly understood phenomenon increasingly seen in the management of pertrochanteric hip fractures with the intramedullary nail. The aim of this study was to investigate the role of bidirectional loading on the medial migration phenomenon, based on unique wear patterns seen on scanning electron microscopy of retrieved implants suggestive of FNE toggling. A total of 18 synthetic femurs (Sawbones, Vashon Island, Washington) with comminuted pertrochanteric fractures were divided into three groups (n = 6 per group). Fracture fixation was performed using the Proximal Femoral Nail Antirotation (PFNA) implant (Synthes, Oberdorf, Switzerland; n = 6). Group 1 was subjected to unidirectional compression loading (600 N), with an elastomer (70A durometer) replacing loose fracture fragments to simulate surrounding soft-tissue tensioning. Group 2 was subjected to bidirectional loading (600 N compression loading, 120 N tensile loading), also with the elastomer replacing loose fracture fragments. Group 3 was subjected to bidirectional loading (600 N compression loading, 120 N tensile loading) without the elastomer. All constructs were tested at 2 Hz for 5000 cycles or until cut-out occurred. The medial migration distance (MMD) was recorded at the end of the testing cycles.Objectives
Methods
A variety of surgical approaches are used for total hip arthroplasty (THA), all with reported advantages and disadvantages. A number of common complications can occur following THA regardless of the approach used. The purpose of this study was to compare five commonly used surgical approaches with respect to the incidence of surgery-related complications. The electronic medical records of all patients who underwent primary elective THA at a single large-volume arthroplasty centre, between 2011 and 2016, with at least two years of follow-up, were reviewed. After exclusion, 3574 consecutive patients were included in the study. There were 1571 men (44.0%) and 2003 women (56.0%). Their mean age and body mass index (BMI) was 63.0 years (Aims
Patients and Methods
Objectives. Osteosynthesis of anterior pubic ramus fractures using one large-diameter screw can be challenging in terms of both surgical procedure and fixation stability. Small-fragment screws have the advantage of following the pelvic cortex and being more flexible. The aim of the present study was to biomechanically compare retrograde
We aimed to determine whether cemented hemiarthroplasty
is associated with a higher post-operative mortality and rate of
re-operation when compared with uncemented hemiarthroplasty. Data
on 19 669 patients, who were treated with a hemiarthroplasty following
a fracture of the hip in a nine-year period from 2002 to 2011, were extracted
from NHS Scotland’s acute admission database (Scottish Morbidity
Record, SMR01). We investigated the rate of mortality at day 0,
1, 7, 30, 120 and one-year post-operatively using 12 case-mix variables
to determine the independent effect of the method of fixation. At
day 0, those with a cemented hemiarthroplasty had a higher rate
of mortality (p <
0.001) compared with those with an uncemented
hemiarthroplasty, equivalent to one extra death per 424 procedures.
By day one this had become one extra death per 338 procedures. Increasing
age and the five-year co-morbidity score were noted as independent
risk factors. By day seven, the cumulative rate of mortality was
less for cemented hemiarthroplasty though this did not reach significance
until day 120. The rate of re-operation was significantly higher
for uncemented hemiarthroplasty. Despite adjusting for 12 confounding
variables, these only accounted for 15% of the observed variability. The debate about the choice of the method of fixation for a hemiarthroplasty
with respect to the rate of mortality or the risk of re-operation
may be largely superfluous. Our results suggest that uncemented
hemiarthroplasties may have a role to play in elderly patients with
significant co-morbid disease. Cite this article:
In March 2012, an algorithm for the treatment
of intertrochanteric fractures of the hip was introduced in our academic
department of Orthopaedic Surgery. It included the use of specified
implants for particular patterns of fracture. In this cohort study,
102 consecutive patients presenting with an intertrochanteric fracture
were followed prospectively (post-algorithm group). Another 117
consecutive patients who had been treated immediately prior to the
implementation of the algorithm were identified retrospectively
as a control group (pre-algorithm group). The total cost of the
implants prior to implementation of the algorithm was $357 457 (mean:
$3055 (1947 to 4133)); compared with $255 120 (mean: $2501 (1052
to 4133)) after its implementation. There was a trend toward fewer complications
in patients who were treated using the algorithm (33% pre- The implementation of an evidence-based algorithm for the treatment
of intertrochanteric fractures reduced costs while maintaining quality
of care with a lower rate of complications and re-admissions. Cite this article:
Most hip fractures treated with modern internal
fixation techniques will heal. However, failures occasionally occur and
require revision procedures. Salvage strategies employed during
revision are based on whether the fixation failure occurs in the
femoral neck, or in the intertrochanteric region. Patient age and
remaining bone stock also influence decision making. For fractures
in young patients, efforts are generally focused on preserving the
native femoral head via osteotomies and repeat internal fixation.
For failures in older patients, some kind of hip replacement is
usually selected. Disuse osteopenia, deformity, bone loss, and stress-risers
from previous internal fixation devices all pose technical challenges
to successful reconstruction. Attention to detail is important in
order to minimise complications. In the majority of cases, good
outcomes have been reported for the various salvage strategies. Cite this article:
Many tumors metastasise to bone, therefore, pathologic
fracture and impending pathologic fractures are common reasons for
orthopedic consultation. Having effective treatment strategies is
important to avoid complications, and relieve pain and preserve
function. Thorough pre-operative evaluation is recommended for medical
optimization and to ensure that the lesion is in fact a metastasis
and not a primary bone malignancy. For impending fractures, various scoring
systems have been proposed to determine the risk of fracture, and
therefore the need for prophylactic stabilisation. Lower score lesions
can often be treated with radiation, while more problematic lesions
may require internal
This prospective study presents the ten-year (5 to 16) clinical and radiological results of 55 primary total hip replacements (THR) using a cementless modular femoral component (S-ROM). All patients had a significant anatomical abnormality which rendered the primary THR difficult. The mean Harris hip score was 36 (12 to 72) pre-operatively, 83 (44 to 100) at five years, and 85 (45 to 99) at ten years. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and short-form (SF)-12 scores were recorded from the year 2000. The mean SF-12 score at five years after surgery was 45.24 (22.74 to 56.58) for the physical component and 54.14 (29.20 to 66.61) for the mental component. By ten years the SF-12 scores were 42.86 (21.59 to 58.95) and 51.03 (33.78 to 61.40), respectively. The mean WOMAC score at five years post-operatively was 25 (0 to 59), and at ten years was 27 (2 to 70). No femoral components were radiologically loose, although five had osteolysis in Gruen zone 1, three had osteolysis in zone 7, and two showed osteolysis in both zones 1 and 7. No osteolysis was observed around or distal to the prosthetic sleeve. No femoral components were revised, although three hips underwent an acetabular revision and two required a liner exchange. At a mean of ten years’ follow-up the S-ROM femoral component implanted for an anatomically difficult primary THR has excellent clinical and radiological results.
Iontophoresis is a novel technique which may be used to facilitate the movement of antibiotics into the substance of bone using an electrical potential applied externally. We have examined the rate of early infection in allografts following application of this technique in clinical practice. A total of 31 patients undergoing revision arthroplasty or surgery for limb salvage received 34 iontophoresed sequential allografts, of which 26 survived for a minimum of two years. The mean serum antibiotic levels after operation were low (gentamicin 0.37 mg/l (0.2 to 0.5); flucloxacillin 1 mg/l (0 to 1) and the levels in the drains were high (gentamicin 40 mg/l (2.5 to 131); flucloxacillin 17 mg/l (1 to 43). There were no early deep infections. Two late infections were presumed to be haemotogenous; 28 of the 34 allografts were retained. In 12 patients with pre-existing proven infection further infection has not occurred at a mean follow-up of 51 months (24 to 82).
We assessed the outcome of patients with Vancouver type B2 and B3 periprosthetic fractures treated with femoral revision using an uncemented extensively porous-coated implant. A retrospective clinical and radiographic assessment of 22 patients with a mean follow-up of 33.7 months was performed. The mean time from the index procedure to fracture was 10.8 years. There were 17 patients with a satisfactory result. Complications in four patients included subsidence in two, deep sepsis in one, and delayed union in one. Concomitant acetabular revision was required in 19 patients. Uncemented extensively porous-coated femoral stems incorporate distally allowing stable fixation. We found good early survival rates and a low incidence of nonunion using this implant.
