AIMS: The common treatment for an undisplaced femoral neck fracture is osteosynthesis. Two major complications of osteosynthesis are non-union and late collapse of the femoral head. We speculated that femoral head perfusion is one of the most important factors that affect the outcome of osteosynthesis after femoral neck fracture. We have preoperatively estimated femoral head perfusion by dynamic MRI positive enhancement integral color mapping (PEICM). The purpose of this study was to evaluate the outcomes of undisplaced femoral neck fractures based on PEICM...

BACKGROUND: It is unclear whether cemented or uncemented hemiarthroplasty is the best treatment option in elderly patients with displaced femoral neck fractures. Previous randomized trials comparing cemented and uncemented hemiarthroplasty have conflicting results. We conducted a randomized controlled trial to compare cemented and uncemented hemiarthroplasty. METHODS: This multicenter parallel-randomized controlled trial included patients of 70 years and older with a displaced femoral neck fracture (Garden type III or IV)...

OBJECTIVES: For patients with femoral neck fractures, total hip arthroplasty (THA) demonstrates superior outcomes compared with hemiarthroplasty. However, hemiarthroplasty remains a common treatment for femoral neck fractures and the conversion rates are unknown. We compared the results of the 2 procedures using a Medicare database. METHODS: We assembled a cohort of 70,242 patients 65 to 90 years of age with an ICD9 diagnosis and matching Current Procedure Terminology code for femoral neck fracture between 2008 and 2012...

Background and purpose - Displaced femoral neck fractures (FNFs) are associated with high rates of mortality during the first postoperative year. The Sernbo score (based on age, habitat, mobility, and mental state) can be used to stratify patients into groups with different 1-year mortality. We assessed this predictive ability in patients with a displaced FNF treated with a hemiarthroplasty or a total hip arthroplasty. Patients and methods - 292 patients (median age 83 (65-99) years, 68% female) with a displaced FNF were included in this prospective cohort study...

Although GWAS have been able to successfully identify dozens of genetic loci associated with bone mineral density (BMD) and osteoporosis related traits, very few of these loci have been confirmed to be causal. This is due to the fact that in a given genetic region there may exist many trait-associated SNPs that are highly correlated. While this correlation is useful for discovering novel associations, the high degree of linkage disequilibrium that persists throughout the genome presents a major challenge to discern which among these correlated variants has a direct effect on the trait...

Background Besides the known intraarticular femoroacetabular impingement (FAI), recently forms of extra-articular impingement of the hip have been increasingly recognized. Recent studies have described an extra-articular impingement between a distal extension of the anterior inferior iliac spine (AIIS) and the femoral neck (AIIS or subspine impingement). Evidently, an association between this subspine impingement and an intraarticular FAI seems to exist. Little is known about the incidence of this impingement type and the value of its radiological diagnostics...

Femoral neck fractures resulting from pregnancy-associated osteoporosis is a rare condition. Herein, we report an undoubted case of pregnancy-associated osteoporosis in a 38-year-old primiparous patient with pre-existing anorexia nervosa who suffered bilateral femoral neck fractures in the third trimester and early post-partum period. Magnetic resonance imaging revealed femoral neck fractures as well as diffuse marrow edema involving both femoral heads, which are considered under ordinary circumstances as characteristic imaging findings of transient osteoporosis of the hip...

We conducted a meta-analysis of studies to examine the risk of vertebral and non-vertebral fractures in patients with ankylosing spondylitis (AS). Additionally, we evaluated the risk factors of vertebral fractures in AS. Two authors independently searched Embase and Medline for studies that had assessed the risk of fractures in patients with AS. Twenty-two studies were eligible for the meta-analysis. Patients with AS had high frequency of vertebral fractures [OR (95% CI): 1.96 (1.52-2.51)]. Major risk factors for vertebral fractures in patients with AS include low BMD at the femoral neck and total hip, male gender, longer disease duration, higher BASDAI, higher BASRI, and possibly inflammatory bowel disease...

The aim of the study was to investigate femoral neck strain during maximal isometric contraction of the hip-spanning muscles. The musculoskeletal and the femur finite-element models from an elderly white woman were taken from earlier studies. The hip-spanning muscles were grouped by function in six hip-spanning muscle groups. The peak hip and knee moments in the model were matched to corresponding published measurements of the hip and knee moments during maximal isometric exercises about the hip and the knee in elderly participants...

INTRODUCTION: Traumatic hip dislocation associated with femur intertrocanteric fracture is a rare and severe injury and it frequently occurs following a high energy trauma, Associated acetabular fractures with this injury are even more rare and potentially cause devastating consequences including avascular necrosis of the femoral head and subsequent early secondary osteoarthritis of the hip joint. PRESENTATION OF CASE: In this case report, we present a 20year old polytraumatized patient with traumatic hip dislocation associated with ipsilateral acetabulum fracture and simultaneous fractures of the ipsilateral femur...

We quantified differences in trabecular volumetric bone mineral density (BMD) of the femoral head between patients with proximal femoral fractures and healthy subjects in the control group by using quantitative computed tomography (QCT) with the purpose of providing guidance for the choice of head screw in the intramedullary nail fixation. Participants suffering from intertrochanteric fractures (n=536 patients) were recruited. In addition, 497 fracture-free, age-matched cases were considered as the control group...

Calciphylaxis causes ischemia in multiple organs and skin ulcers owing to progressive calcification in small and medial arteries. It has a poor prognosis and often occurs in patients with hyperparathyroidism associated with end-stage renal failure and those undergoing hemodialysis. Here, we present a case of calciphylaxis associated with a wide range of symptoms, including lower thigh skin ulcers, a rectovaginal fistula, and femoral neck fracture. The patient underwent multiple treatments. However, she eventually died of cardiac failure...

Early detection of adverse local tissue reaction (ALTR) to prosthetic hip wear debris is vital to improve the success of revision surgery. Magnetic resonance imaging with metal artefact reduction sequencing (MARS MRI) is considered the modality of choice to provide cross-sectional imaging of the soft tissues. The areas adjacent to the prosthesis are, however, not readily imaged using these protocols. Ultrasound has also been recommended as an imaging modality in the follow-up of hip replacement surgery. We decided to characterise the typical ultrasound findings in a group of patients undergoing routine biennial review of arthroplastic hips with particular reference to the hip capsule, femoral neck and iliopsoas bursa and tendon adjacent to the implant...

OBJECTIVE: Irisin derived from muscle in response to exercise may be the molecular entity responsible for muscle wasting-osteoporosis connectivity in the elderly. The objective of the study was to determine whether serum Irisin (sIrisin) provides information on hip fracture prediction which were independent of bone mineral density (BMD) and the fracture risk assessment tool (FRAX) algorithm. METHODS: This study enrolled 160 older women (ages, 70-90 y) with minimal trauma hip fractures (MTHFs) and 160 age-matched women without fracture serving as controls...

There is little knowledge about the spatial distribution differences in volumetric bone mineral density and cortical bone structure at the proximal femur between femoral neck fractures and trochanteric fractures. In this case-control study, a total of 93 women with fragility hip fractures, 72 with femoral neck fractures (mean ± SD age: 70.6 ± 12.7 years) and 21 with trochanteric fractures (75.6 ± 9.3 years), and 50 control subjects (63.7 ± 7.0 years) were included for the comparisons. Differences in the spatial distributions of volumetric bone mineral density, cortical bone thickness, cortical volumetric bone mineral density and volumetric bone mineral density in a layer adjacent to the endosteal surface were investigated using voxel-based morphometry (VBM) and surface-based statistical parametric mapping (SPM)...
