BACKGROUND: Hip fractures cause increased mortality and disability and consume enormous healthcare resources. Only 46% of hip fracture patients have osteoporosis at the total hip according to dual-energy X-ray absorptiometry (DXA) measurement. Cortical porosity increases with ageing and is believed to be important for bone strength. OBJECTIVE: To investigate whether older women with hip fracture have higher cortical porosity than controls, and if so whether this difference is independent of clinical risk factors and areal bone mineral density (aBMD)...

BACKGROUND: The survivors after hip fracture often report severe pain and loss of physical functioning. The poor outcomes cause negative impact on the person's physical functioning and quality of life and put a financial burden on society. Rehabilitation is important to improve physical functioning after hip fracture. To maintain the continuity in rehabilitation we have an assumption that it is of utmost importance to continue and progress the functional training that already started at the hospital, while the patients are transferred to short-term stays in a nursing home before they are returning to home...

Margaret E Thompson, Mary Barth Noel
The assessment of nutritional status in adults should begin with a complete history, including intake of fruits and vegetables, sources of fat, and added sugar (eg, sugar-sweetened beverages). The history should include social factors that may impede a patient's ability to obtain food, as well as any factors that might interfere with preparing, chewing, and digesting food and absorbing nutrients. The physical examination should include measurement of height and weight and calculation of body mass index. It also may include measurements of waist circumference and waist to hip ratio, and an evaluation of strength...

BACKGROUND: Boys with autism spectrum disorder (ASD) have lower areal bone mineral density (aBMD) than typically developing controls (TDC). Studies of volumetric BMD (vBMD) and bone microarchitecture provide information about fracture risk beyond that provided by aBMD but are currently lacking in ASD. OBJECTIVES: To assess ultradistal radius and distal tibia vBMD, bone microarchitecture and strength estimates in adolescent boys with ASD compared to TDC. DESIGN/METHODS: Cross-sectional study of 34 boys (16 ASD, 18 TDC) that assessed (i) aBMD at the whole body (WB), WB less head (WBLH), hip and spine using dual X-ray absorptiometry (DXA), (ii) vBMD and bone microarchitecture at the ultradistal radius and distal tibia using high-resolution peripheral quantitative CT (HRpQCT), and (iii) bone strength estimates (stiffness and failure load) using micro-finite element analysis (FEA)...

BACKGROUND: Internal snapping hip is a common clinical condition, characterized by an audible or palpable snap of the medial compartment of the hip. In most cases it is asymptomatic, while in a few patients, mostly in athletes who participate in activities requiring extremes of hip range of motion, the snap may become painful (internal snapping hip syndrome - ISHS). MATERIALS AND METHODS: This is a review of current literature, focused on the pathogenesis, diagnosis and treatment of ISHS...

Sclerostin, a glycoprotein produced primarily by osteocytes, blocks the canonical Wnt signaling bone formation pathway. Romosozumab is a humanized monoclonal antibody to sclerostin that binds to sclerostin, permitting the engagement of Wnt ligands with their co-receptors, resulting in an increase in bone formation and bone mineral density (BMD). Clinical studies with romosozumab have shown dramatic improvements in BMD at the spine and hip. Romosozumab is associated with improvement in bone strength through mechanisms that include increases in bone formation and, different from classical osteoanabolic agents, suppression of bone resorption...

BACKGROUND: Most femoral components used now for total hip arthroplasty are modular, requiring a strong connection at assembly. The aim of this study was to assess the effect of assembly force on the strength of head-trunnion interface and to measure the initial displacement of the head on the trunnion with different assembly forces. METHODS: Three assembly load levels were assessed (A: 2 kN, B: 4 kN, C: 6 kN) with 4 implants in each group. The stems were mounted in a custom rig and the respective assembly loads were applied to the head at a constant rate of 0...

Adam M Ali, Charles E R Gibbons
BACKGROUND: Early readmission to hospital after hip fracture is associated with increased mortality and significant costs to the healthcare system. There is growing interest in the use of 30-day readmission rates as a metric of hospital performance. Identifying patients at increased risk of readmission after hip fracture may enable pre-emptive action to mitigate this risk and the development of effective methods of risk-adjustment to allow readmission to be used as a reliable measure of hospital performance...

OBJECTIVE: To investigate whether bodyweight exercises can induce comparable levels of muscle activity as conventional machine exercises in chronic stroke patients. METHODS: Eighteen patients performed three repetitions of bilateral- and unilateral machine leg press and the bodyweight exercises chair rise and hip thrust. Surface electromyography (EMG) was recorded from 10 lower extremity muscles and normalized to maximal EMG (nEMG) of the non-paretic leg. RESULTS: For the paretic leg, the bodyweight exercises showed comparable levels of nEMG in 6 out of 10 muscles compared with the bilateral leg press...

BACKGROUND: In patients with a transfemoral amputation socket-related problems are associated with reduced prosthetic use, activity, and quality of life. Furthermore, gait asymmetries are present that may explain secondary complaints. Bone-anchored prostheses (BAPs) may help these patients. Two types of BAP are available, screw and press-fit implants. Rehabilitation following surgery for a press-fit BAP is poorly described. PURPOSE: To describe a rehabilitation program designed to minimize compensation strategies and increase activity using a case-report of an active, 70-year-old man with a traumatic transfemoral amputation who had used a socket prosthesis for 52 years and received a press-fit BAP [Endo-Exo Femoral Prosthesis - EEFP]...

Aseptic loosening at alloy-cement interfaces constitutes a main failure mechanism of cemented total hip replacements (THR). As a potential solution we investigated the effect of metal primers containing phosphoric and phosphonic acid on shear bond strength (SBS) of bone cement to THR alloys (CoCrMo, TiAlNb) and pure tin (Sn) substrates (20×8×3 mm). Metal surfaces were modified by polishing or Al2O3 blasting and primer application. Substrates without primer treatment served as references. Cylindrical cement pins (Ø 5mm) were polymerised onto substrate surfaces and aging (1, 5, 14 and 150 days) was simulated in aqueous NaCl solution (0...
