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:
An 81-year-old woman presented with a fracture
in the left femur. She had well-fixed bilateral hip replacements
and had received long-term bisphosphonate treatment. Prolonged bisphosphonate
use has been recently linked with atypical subtrochanteric and diaphyseal
femoral fractures. While the current definition of an atypical fracture
of the femur excludes peri-prosthetic fractures, this case suggests
that they do occur and should be considered in patients with severe
osteopenia. Union of the fracture followed cessation of bisphosphonates
and treatment with teriparatide. Thus, this case calls into question
whether prophylactic
The prevalence of ipsilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA) is rising in concert with life expectancy, putting more patients at risk for interprosthetic femur fractures (IPFFs). Our study aimed to assess treatment methodologies, implant survivorship, and IPFF clinical outcomes. A total of 76 patients treated for an IPFF from February 1985 to April 2018 were reviewed. Prior to fracture, at the hip/knee sites respectively, 46 femora had primary/primary, 21 had revision/primary, three had primary/revision, and six had revision/revision components. Mean age and BMI were 74 years (33 to 99) and 30 kg/m2 (21 to 46), respectively. Mean follow-up after fracture treatment was seven years (2 to 24).Aims
Methods
The direct anterior approach (DAA) for total hip arthroplasty (THA) has potential advantages over other approaches and is most commonly performed with the patient in the supine position. We describe a technique for DAA THA with the patient in the lateral decubitus position and report the early clinical and radiological outcomes, the characteristics of the learning curve, and perioperative complications. All primary DAA THAs performed in the lateral position by a single surgeon over a four-year period from the surgeon’s first case using the technique were identified from a prospectively collected database. Modified Harris Hip Scores (mHHS) were collected to assess clinical outcome, and routine radiological analysis was performed. Retrospective review of the medical records identified perioperative complications, the characteristics of the learning curve, and revisions.Aims
Methods
During the COVID-19 pandemic, many patients continue to require urgent surgery for hip fractures. However, the impact of COVID-19 on perioperative outcomes in these high-risk patients remains unknown. The objectives of this study were to establish the effects of COVID-19 on perioperative morbidity and mortality, and determine any risk factors for increased mortality in patients with COVID-19 undergoing hip fracture surgery. This multicentre cohort study included 340 COVID-19-negative patients versus 82 COVID-19-positive patients undergoing surgical treatment for hip fractures across nine NHS hospitals in Greater London, UK. Patients in both treatment groups were comparable for age, sex, body mass index, fracture configuration, and type of surgery performed. Predefined perioperative outcomes were recorded within a 30-day postoperative period. Univariate and multivariate analysis were used to identify risk factors associated with increased risk of mortality.Aims
Methods
Surgical treatment of hip fracture is challenging; the bone is porotic and fixation failure can be catastrophic. Novel implants are available which may yield superior clinical outcomes. This study compared the clinical effectiveness of the novel X-Bolt Hip System (XHS) with the sliding hip screw (SHS) for the treatment of fragility hip fractures. We conducted a multicentre, superiority, randomized controlled trial. Patients aged 60 years and older with a trochanteric hip fracture were recruited in ten acute UK NHS hospitals. Participants were randomly allocated to fixation of their fracture with XHS or SHS. A total of 1,128 participants were randomized with 564 participants allocated to each group. Participants and outcome assessors were blind to treatment allocation. The primary outcome was the EuroQol five-dimension five-level health status (EQ-5D-5L) utility at four months. The minimum clinically important difference in utility was pre-specified at 0.075. Secondary outcomes were EQ-5D-5L utility at 12 months, mortality, residential status, mobility, revision surgery, and radiological measures.Aims
Methods
Postoperative delirium (POD) and postoperative cognitive decline (POCD) are common surgical complications. In the UK, the Best Practice Tariff incentivizes the screening of delirium in patients with hip fracture. Further, a National Hip Fracture Database (NHFD) performance indicator is the reduction in the incidence of POD. To aid in its recognition, we sought to determine factors associated with POD and POCD in patients with hip fractures. We interrogated the NHFD data on patients presenting with hip fractures to our institution from 2016 to 2018. POD was determined using the 4AT score, as recommended by the NHFD and UK Department of Health. POCD was defined as a decline in Abbreviated Mental Test Score (AMTS) of two or greater. Using logistic regression, we adjusted for covariates to identify factors associated with POD and POCD.Aims

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
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
We chose unstable extra-capsular hip fractures as our study group
because these types of fractures suffer the largest blood loss.
We hypothesised that tranexamic acid (TXA) would reduce total blood
loss (TBL) in extra-capsular fractures of the hip. A single-centre placebo-controlled double-blinded randomised
clinical trial was performed to test the hypothesis on patients
undergoing surgery for extra-capsular hip fractures. For reasons
outside the control of the investigators, the trial was stopped
before reaching the 120 included patients as planned in the protocol. Aims

This conversation represents an attempt by several
arthroplasty surgeons to critique several abstracts presented over
the last year as well as to use them as a jumping off point for trying
to figure out where they fit in into our current understanding of
multiple issues in modern hip and knee arthroplasty.
An atypical femoral fracture (AFF), with a transverse
fracture radiologically through the lateral cortex is a rare but serious
condition. In order to improve our ability to identify patients
with this condition, we retrospectively surveyed all subtrochanteric,
peri-implant and diaphyseal femoral fractures in patients aged ≥ 65
years who underwent surgical treatment at our hospital between 2004
and 2011. We describe the incidence of atypical fractures and their characteristics,
with observational data including a review of the hospital and general
practitioner records. Clinical outcomes were evaluated using the
Harris hip score (HHS) and the timed up-and-go (TUG) test. Atypical fractures only occurred in women with an incidence of
9.8 per 100 000 person-years. The incidence in those who were treated
with bisphosphonates was 79.0 per 100 000 person-years; eight of
17 fractures occurred around metal implants. There was a high incidence
of delayed union and revision surgery. A total of nine patients (ten
AFFs) were available for review at a mean follow-up of 36.5 months
(10 to 104). The clinical outcome was poor with a mean HHS of 58.9
(95% CI 47.4 to 70.4) and a mean TUG test of 25.7 s (95% CI 12.7
to 38.8). The delay in diagnosis and treatment of AFF may result from a
lack of knowledge of this condition. 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 fixation. Intramedullary fixation is generally
preferred due to favorable biomechanics. Arthroplasty may be required
for lesions with massive bony destruction where internal fixation
attempts are likely to fail. Radiation may also be useful postoperatively
to minimise construct failure due to tumor progression.
The purpose of this paper is to discuss the risk
factors, prevention strategies, classification, and treatment of
intra-operative femur fractures sustained during primary and revision
total hip arthroplasty.
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).
