Corticosteroid use has been implicated in the
development of osteonecrosis of the femoral head (ONFH). The exact mechanism

With greater numbers of younger patients undergoing
total hip replacement (THR), the effect of patient age on the diameter
of the femoral canal may become more relevant. This study aimed
to investigate the relationship between the diameter of the diaphysis
of the femoral canal with increasing age in a large number of patients
who underwent THR. A total of 1685 patients scheduled for THR had
their femoral dimensions recorded from calibrated radiographs. There
were 736 males and 949 females with mean ages of 67.1 years (34
to 92) and 70.2 years (29 to 92), respectively. The mean diameter
of the femoral canal was 13.3 mm (8.0 to 23.0) for males and 12.7
mm (6.0 to 26.0) for females. There was a poor correlation between
age and the diameter of the canal in males (r = 0.071, p = 0.05)
but a stronger correlation in females (r = 0.31, p <
0.001). The diameter of the femoral canal diameter of a female patient
undergoing THR could be predicted to increase by 3.2 mm between
the ages of 40 and 80 years, in contrast a male would be expected
to experience only a 0.6 mm increase during the same period. This
increase in the diameter of the canal with age might affect the
long-term survival of the femoral component in female patients. Cite this article:
Our primary aim was to establish the proportion of female orthopaedic consultants who perform arthroplasty via cases submitted to the National Joint Registry (NJR), which covers England, Wales, Northern Ireland, the Isle of Man, and Guernsey. Secondary aims included comparing time since specialist registration, private practice participation, and number of hospitals worked in between male and female surgeons. Publicly available data from the NJR was extracted on the types of arthroplasty performed by each surgeon, and the number of procedures of each type undertaken. Each surgeon was cross-referenced with the General Medical Council (GMC) website, using GMC number to extract surgeon demographic data. These included sex, region of practice, and dates of full and specialist registration.Aims

Recently, gender-specific designs of total knee replacement have been developed to accommodate anatomical differences between males and females. We examined a group of male and female distal femora matched for age and height, to determine if there was a difference in the aspect ratio (mediolateral distance versus anteroposterior distance) and the height of the anterior flange between the
Aims. The aim of this study was to determine if positive Waddell signs
were related to patients’ demographics or to perception of their
quality of life. Patients and Methods. This prospective cross-sectional study included 479 adult patients
with back pain from a university spine centre. Each completed SF-12
and Oswestry Disability Index (ODI) questionnaires and underwent
standard spinal examinations to elicit Waddell signs. The relationship
between Waddell signs and age,
Aims. Patients with an acute Achilles tendon rupture (ATR) take a long
time to heal, have a high incidence of deep vein thrombosis (DVT)
and widely variable functional outcomes. This variation in outcome
may be explained by a lack of knowledge of adverse factors, and
a subsequent shortage of appropriate interventions. . Patients and Methods. A total of 111 patients (95 men, 16 women; mean age 40.3, standard
deviation 8.4) with an acute total ATR were prospectively assessed.
At one year post-operatively a uniform outcome score, Achilles Combined
Outcome Score (ACOS), was obtained by combining three validated,
independent, outcome measures: Achilles tendon Total Rupture Score,
heel-rise height test, and limb symmetry heel-rise height. Predictors
of ACOS included treatment;
We studied the integrity of the rotator cuff in both dominant and non-dominant shoulders of 90 asymptomatic adults between the ages of 30 and 99 years using ultrasound. The criteria for diagnosis had been validated on unembalmed cadaver specimens. We found no statistically significant difference in the incidence of impingement findings between dominant and non-dominant arms or between
Radiographs of the shoulders of 84 asymptomatic individuals aged between 40 and 83 years were evaluated to determine changes in 23 specific areas. Two fellowship-trained orthopaedic radiologists graded each area on a scale of 0 to II (normal 0, mild changes I, advanced changes II). Logistic regression analysis indicated age to be a significant predictor of change (p <
0.05) for sclerosis of the medial acromion and lateral clavicle, the presence of subchondral cysts in the acromion, formation of osteophytes at the inferior acromion and clavicle, and narrowing and degeneration of the acromioclavicular joint.
Orthopaedics has been left behind in the worldwide drive towards diversity and inclusion. In the UK, only 7% of orthopaedic consultants are female. There is growing evidence that diversity increases innovation as well as patient outcomes. This paper has reviewed the literature to identify some of the common issues affecting female surgeons in orthopaedics, and ways in which we can address them: there is a wealth of evidence documenting the differences in the journey of men and women towards a consultant role. We also look at lessons learned from research in the business sector and the military. The ‘Hidden Curriculum’ is out of date and needs to enter the 21st century: microaggressions in the workplace must be challenged; we need to consider more flexible training options and support trainees who wish to become pregnant; mentors, both male and female, are imperative to provide support for trainees. The world has changed, and we need to consider how we can improve diversity to stay relevant and effective. Cite this article:
We report the long-term survival and functional
outcome of the Birmingham Hip Resurfacing (BHR) in patients aged <
50 years at operation, and explore the factors affecting survival.
Between 1997 and 2006, a total of 447 BHRs were implanted in 393
patients (mean age 41.5 years (14.9 to 49.9)) by one designing surgeon.
The mean follow-up was 10.1 years (5.2 to 14.7), with no loss to
follow-up. In all, 16 hips (3.6%) in 15 patients were revised, giving
an overall cumulative survival of 96.3% (95% confidence interval
(CI) 93.7 to 98.3) at ten years and 94.1% (95% CI 84.9 to 97.3)
at 14 years. Using aseptic revision as the endpoint, the survival
for men with primary osteoarthritis (n = 195) was 100% (95% CI 100
to 100) at both ten years and 14 years, and in women with primary
osteoarthritis (n = 109) it was 96.1% (95% CI 90.1 to 99.9) at ten
years and 91.2% (95% CI 68.6 to 98.7) at 14 years. Female gender
(p = 0.047) and decreasing femoral head size (p = 0.044) were significantly
associated with an increased risk of revision. The median Oxford
hip score (OHS, modified as a percentage with 100% indicating worst
outcome) at last follow-up was 4.2% (46 of 48; interquartile range
(IQR) 0% to 24%) and the median University of California, Los Angeles
(UCLA) score was 6.0 (IQR 5 to 8). Men had significantly better
OHS (p = 0.02) and UCLA scores (p = 0.01) than women. The BHR provides
excellent survival and functional results in men into the second
decade, with good results achieved in appropriately selected women. Cite this article:
The purpose of this study was to investigate
whether a gender-specific high-flexion posterior-stabilised (PS)
total knee replacement (TKR) would offer advantages over a high-flex
PS TKR regarding range of movement (ROM), ‘feel’ of the knee, pain
and satisfaction, as well as during activity. A total of 24 female
patients with bilateral osteoarthritis entered this prospective,
blind randomised trial in which they received a high-flex PS TKR
in one knee and a gender-specific high-flexion PS TKR in the other
knee. At follow-up, patients were assessed clinically measuring
ROM, and questioned about pain, satisfaction and daily ‘feel’ of
each knee. Patients underwent gait analysis pre-operatively and
at one year, which yielded kinematic, kinetic and temporospatial
parameters indicative of knee function during gait. At final follow-up
we found no statistically significant differences in ROM (p = 0.82).
The median pain score was 0 (0 to 8) in both groups (p = 0.95).
The median satisfaction score was 9 (4 to 10) in the high-flex group
and 8 (0 to 10) in the gender-specific group (p = 0.98). The median
‘feel’ score was 9 (3 to 10) in the high-flex group and 8 (0 to
10) in the gender-specific group (p = 0.66). Gait analysis showed
no statistically significant differences between the two prosthetic
designs in any kinematic, kinetic or temporospatial parameters. Both designs produced good clinical results with
Aims. Using 90% of final height as a benchmark, we sought to develop
a quick, quantitative and reproducible method of estimating skeletal
maturity based on topographical changes in the distal femoral physis. Patients and Methods. Serial radiographs of the distal femoral physis three years prior
to, during, and two years following the chronological age associated
with 90% of final height were analyzed in 81 healthy children. The
distance from the tip of the central peak of the distal femoral
physis to a line drawn across the physis was normalized to the physeal width. Results. A total of 389 radiographs of the distal femur with corresponding
Greulich and Pyle bone ages and known chronological ages were measured.
Children reached 90% of final height at a mean age of 11.3 years
(. sd. 0.8) for girls and 13.2 years (. sd. 0.6) for
boys. Linear regression analysis showed higher correlation coefficent
in predicting the true age at 90% of final height using chronological

Aims. This study evaluates risk factors influencing fracture characteristics for postoperative periprosthetic femoral fractures (PFFs) around cemented stems in total hip arthroplasty. Methods. Data were collected for PFF patients admitted to eight UK centres between 25 May 2006 and 1 March 2020. Radiographs were assessed for Unified Classification System (UCS) grade and AO/OTA type. Statistical comparisons investigated relationships by age,
Aims. Our aim was to examine the Elixhauser and Charlson comorbidity indices, based on administrative data available before surgery, and to establish their predictive value for mortality for patients who underwent hip arthroplasty in the management of a femoral neck fracture. Patients and Methods. We analyzed data from 42 354 patients from the Swedish Hip Arthroplasty Register between 2005 and 2012. Only the first operated hip was included for patients with bilateral arthroplasty. We obtained comorbidity data by linkage from the Swedish National Patient Register, as well as death dates from the national population register. We used univariable Cox regression models to predict mortality based on the comorbidity indices, as well as multivariable regression with age and
Aims. This study aimed to evaluate implant survival of reverse hybrid
total hip arthroplasty (THA) at medium-term follow-up. Patients and Methods. A consecutive series of 1082 THAs in 982 patients with mean follow-up
of 7.9 years (5 to 11.3) is presented. Mean age was 69.2 years (21
to 94). Of these, 194 (17.9%) were in patients under 60 years, 663
(61.3%) in female patients and 348 (32.2%) performed by a trainee.
Head size was 28 mm in 953 hips (88.1%) or 32 mm in 129 hips (11.9%).
Survival analysis was performed and subgroups compared using log
rank tests. Results. Ten-year survival (122 hips at risk) was 97.2% (95% confidence
interval (CI) 95.77 to 98.11) for all-cause revision. There was
no difference in survival by age (p = 0.50),
Aims. We aimed to determine the effect of dementia and Parkinson’s
disease on one, three and 12-month mortality following surgery for
fracture of the hip in elderly patients from an Asian population. Patients and Methods. Using a random sample of patients taken from the Taiwan National
Health Insurance Research Database, this retrospective cohort study
analyzed the data on 6626 elderly patients who sustained a fracture
of the hip between 1997 and 2012 who had ICD-9 codes within the
general range of hip fracture (820.xx). We used Cox regression to estimate
the risk of death associated with dementia, Parkinson’s disease
or both, adjusting for demographic, clinical, treatment, and provider
factors. Results. Among 6626 hip fracture patients, 10.20% had dementia alone,
5.60% had Parkinson’s disease alone, and 2.67% had both. Corresponding
one-year mortality rates were 15.53%, 11.59%, and 15.82%, compared
with 9.22% for those without neurological illness. Adjusted hazard
ratio for one-year mortality was 1.45 (95% confidence intervals
(CI) 1.17 to 1.79) for those with dementia, and 1.57 (95% CI 1.07
to 2.30) with both dementia and Parkinson’s disease versus patients
with neither. There was no significant association with death for
Parkinson’s disease alone. Age, male
