There is an increased risk of fracture following
osteoplasty of the femoral neck for cam-type femoroacetabular impingement
(FAI). Resection of up to 30% of the anterolateral head–neck junction
has previously been considered to be safe, however, iatrogenic fractures
have been reported with resections within these limits. We re-evaluated
the amount of safe resection at the anterolateral femoral head–neck
junction using a biomechanically consistent model. In total, 28 composite bones were studied in four groups: control,
10% resection, 20% resection and 30% resection. An axial load was
applied to the adducted and flexed femur. Peak load, deflection
at time of fracture and energy to fracture were assessed using comparison
groups. There was a marked difference in the mean peak load to fracture
between the control group and the 10% resection group (p <
0.001).
The control group also tolerated significantly more deflection before
failure (p <
0.04). The mean peak load (p = 0.172), deflection
(p = 0.547), and energy to fracture (p = 0.306) did not differ significantly between
the 10%, 20%, and 30% resection groups. Any resection of the anterolateral quadrant of the femoral head–neck
junction for FAI significantly reduces the load-bearing capacity
of the proximal femur. After initial resection of cortical bone,
there is no further relevant loss of stability regardless of the
amount of trabecular bone resected. Based on our findings we recommend any patients who undergo anterolateral
femoral head–neck junction osteoplasty should be advised to modify
their post-operative routine until cortical remodelling occurs to
minimise the subsequent fracture risk. Cite this article:

Young adults with hip pain secondary to femoroacetabular
impingement (FAI) are rapidly being recognised as an important cohort
of orthopaedic patients. Interest in FAI has intensified over the
last decade since its recognition as a precursor to arthritis of
the hip and the number of publications related to the topic has
increased exponentially in the last decade. Although not all patients
with abnormal hip morphology develop osteoarthritis (OA), those
with FAI-related joint damage rapidly develop premature OA. There
are no explicit diagnostic criteria or definitive indications for
surgical intervention in FAI. Surgery for symptomatic FAI appears
to be most effective in younger individuals who have not yet developed
irreversible OA. The difficulty in predicting prognosis in FAI means
that avoiding unnecessary surgery in asymptomatic individuals, while
undertaking intervention in those that are likely to develop premature
OA poses a considerable dilemma. FAI treatment in the past has focused
on open procedures that carry a potential risk of complications. Recent developments in hip arthroscopy have facilitated a minimally
invasive approach to the management of FAI with few complications
in expert hands. Acetabular labral preservation and repair appears
to provide superior results when compared with debridement alone.
Arthroscopic correction of structural abnormalities is increasingly becoming
the standard treatment for FAI, however there is a paucity of high-level
evidence comparing open and arthroscopic techniques in patients
with similar FAI morphology and degree of associated articular cartilage damage.
Further research is needed to develop an understanding of the natural
course of FAI, the definitive indications for surgery and the long-term
outcomes. Cite this article:
We examined the morphology of mammalian hips asking whether evolution can explain the morphology of impingement in human hips. We describe two stereotypical mammalian hips, coxa recta and coxa rotunda. Coxa recta is characterised by a straight or aspherical section on the femoral head or head-neck junction. It is a sturdy hip seen mostly in runners and jumpers. Coxa rotunda has a round femoral head with ample head-neck offset, and is seen mostly in climbers and swimmers. Hominid evolution offers an explanation for the variants in hip morphology associated with impingement. The evolutionary conflict between upright gait and the birth of a large-brained fetus is expressed in the female pelvis and hip, and can explain pincer impingement in a coxa profunda. In the male hip, evolution can explain cam impingement in coxa recta as an adaptation for running.
Fixation techniques used in the treatment of slipped capital femoral epiphysis (SCFE) that allow continued growth of the femoral neck, rather than inducing epiphyseal fusion in situ, have the advantage of allowing remodelling of the deformity. The aims of this study were threefold: to assess whether the Free-Gliding (FG) SCFE screw prevents further slip; to establish whether, in practice, it enables lengthening and gliding; and to determine whether the age of the patient influences the extent of glide. All patients with SCFE who underwent fixation using FG SCFE screws after its introduction at our institution, with minimum three years’ follow-up, were reviewed retrospectively as part of ongoing governance. All pre- and postoperative radiographs were evaluated. The demographics of the patients, the grade of slip, the extent of lengthening of the barrel of the screw and the restoration of Klein’s line were recorded. Subanalysis was performed according to sex and age.Aims

The Single Assessment Numerical Evalution (SANE) score is a pragmatic alternative to longer patient-reported outcome measures (PROMs). The purpose of this study was to investigate the concurrent validity of the SANE and hip-specific PROMs in a generalized population of patients with hip pain at a single timepoint upon initial visit with an orthopaedic surgeon who is a hip preservation specialist. We hypothesized that SANE would have a strong correlation with the 12-question International Hip Outcome Tool (iHOT)-12, the Hip Outcome Score (HOS), and the Hip disability and Osteoarthritis Outcome Score (HOOS), providing evidence for concurrent validity of the SANE and hip-specific outcome measures in patients with hip pain. This study was a cross-sectional retrospective database analysis at a single timepoint. Data were collected from 2,782 patients at initial evaluation with a hip preservation specialist using the iHOT-12, HOS, HOOS, and SANE. Outcome scores were retrospectively analyzed using Pearson correlation coefficients.Aims

Young adults undergoing total hip arthroplasty (THA) largely have different indications for surgery, preoperative function, and postoperative goals compared to a standard patient group. The aim of our study was to describe young adult THA preoperative function and quality of life, and to assess postoperative satisfaction and compare this with functional outcome measures. A retrospective cohort analysis of young adults (aged < 50 years) undergoing THA between May 2018 and May 2023 in a single tertiary centre was undertaken. Median follow-up was 31 months (12 to 61). Oxford Hip Score (OHS) and focus group-designed questionnaires were distributed. Searches identified 244 cases in 225 patients. Those aged aged under 30 years represented 22.7% of the cohort. Developmental dysplasia of the hip (50; 45.5%) and Perthes’ disease (15; 13.6%) were the commonest indications for THA.Aims

Patients and Methods
In the UK, the NHS generates an estimated 25 megatonnes of carbon dioxide equivalents (4% to 5% of the nation’s total carbon emissions) and produces over 500,000 tonnes of waste annually. There is limited evidence demonstrating the principles of sustainability and its benefits within orthopaedic surgery. The primary aim of this study was to analyze the environmental impact of orthopaedic surgery and the environmentally sustainable initiatives undertaken to address this. The secondary aim of this study was to describe the barriers to making sustainable changes within orthopaedic surgery. A literature search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines through EMBASE, Medline, and PubMed libraries using two domains of terms: “orthopaedic surgery” and “environmental sustainability”.Aims
