Hip fractures and femoral bone mineral density in male former elite athletes

2009

We studied whether vigorous physical activity in young adulthood is associated with higher femoral bone density and lower risk of hip fracture at older age in men.A cohort of former male elite athletes (n=2147) and matched control subjects (n=1467) were studied for their leisure physical activity, and for fragility fractures at the hip (proximal femur) by Cox regression. Areal bone mineral densities (aBMD) at femoral neck and trochanter region were measured using dual-energy X-ray absorptiometry in a subgroup of the former athletes (n=87; median age 59 years) and in a population-based control group (n=194) and compared by general linear models.After their active sporting careers, the former…

The Association Between Bone Mineral Density and Airflow Limitation in a Cohort of Fit Elderly Women

2016

Purpose: As studies examining the association between bone mineral density (BMD) and airflow limitation (AL) have produced conflicting results, the current one set out to analyze if and to what degree there are any correlations between these variables in a population of fit elderly women. Methods: One hundred and twenty-one non-smoking, fit and healthy women (age ≥ 65 years) underwent anthropometric assessment, laboratory testing (serum 25-hydroxy vitamin D, parathormone, and cytokine levels), pulmonary function testing (PFT), and dual-energy X-ray absorptiometry to evaluate BMD values of the lumbar and femoral regions. Results: A significant positive association was found between FEV1/FVC …

A new replacement name for the fossil spider Veterator Petrunkevitch, 1963 (Arthropoda: Arachnida: Araneae)

2021

A junior homonym was detected in the genera of fossil Araneae and the following replacement name is proposed within the family Trochanteriidae: Neoveterator Ceccolini & Cianferoni nom. nov. pro Veterator Petrunkevitch, 1963 nec Laws, 1944. Eight new combinations (comb. nov.) are proposed.

In Silico Finite Element Modeling of Stress Distribution in Osteosynthesis after Pertrochanteric Fractures

2022

A stabilization method of pertrochanteric femur fractures is a contentious issue. Here, we assess the feasibility of rapid in silico 2D finite element modeling (FEM) to predict the distribution of stresses arising during the two most often used stabilization methods: gamma nail fixation (GNF) and dynamic hip screw (DHS). The modeling was based on standard pre-surgery radiographs of hip joints of 15 patients with pertrochanteric fractures of type A1, A2, and A3 according to the AO/OTA classification. The FEM showed that the stresses were similar for both GNF and DHS, with the medians ranging between 53–60 MPa and consistently lower for A1 than A3 fractures. Stresses also appeared in the fixa…

The assessment of vertebral fractures in elderly women with recent hip fractures: the BREAK Study

2012

This study aimed to evaluate the prevalence of vertebral fractures in elderly women with a recent hip fracture. The burden of vertebral fractures expressed by the Spinal Deformity Index (SDI) is more strictly associated with the trochanteric than the cervical localization of hip fracture and may influence short-term functional outcomes. INTRODUCTION: This study aimed to determine the prevalence and severity of vertebral fractures in elderly women with recent hip fracture and to assess whether the burden of vertebral fractures may be differently associated with trochanteric hip fractures with respect to cervical hip fractures. METHODS: We studied 689 Italian women aged 60 years or over with …

Greater Trochanteric Pain Syndrome: What is the Meaning?

2011

Greater trochanteric pain syndrome (GTPS) is a common cause of lower extremity pain. This is frequently attributed to trochanteric bursitis and distension of the subgluteal bursae. Patients are suffering from pain radiating to the posterolateral aspect of the thigh, paraesthesiae in the legs, and tenderness over the iliotibial tract. Often the symptoms are mild, with the patient treating himself successfully through activity modification and other conservative measures. including relative rest, ice, compression, elevation, anti-inflammatory medication and treatment modalities such as ultrasound and electrical stimulation, combined with a structured rehabilitation program. Patients whose sym…

Der Einsatz der Tumorprothese bei sekundär-neoplastischer Destruktion des proximalen Femurendes

2008

Total hip arthroplasty was performed with PMMA-augmented tumor prostheses in 42 individuals suffering from metastatic destruction of the proximal end of the femur at the Orthopedic University Hospital Mainz from 1980 to 1992. Neoplastic lesions had been triggered by carcinomas of the breast in 25 female patients. 24 of our patients presented with pathologic fractures. In all patients capable of walking preoperatively early mobilization could be attained by total hip arthroplasty. Pain relief was achieved in each patient. Resection of the major trochanter and, partially, of the pelvitrochanteric muscle sleeve entailed luxation of the prosthesis six times in 5 individuals during the first pos…

Cementless total hip replacement with subtrochanteric femoral shortening for severe developmental dysplasia of the hip.

2003

Total joint replacement in patients suffering from developmental dysplasia of the hip poses specific technical difficulties due to insufficient bone stock at the site of the original and secondary acetabulum and a narrow, cranially displaced proximal femur. Twelve hips with severe congenital dislocation (4 Crowe type II, 5 type III, 3 type IV) were treated with cementless, porous structured total hip replacement. The cup was implanted at the anatomic height, a femoral segment was resected below the minor trochanter to reduce the femoral component in all cases. One femoral component was exchanged for a longer stem after 2 months due to insufficient fit and fill. After a mean follow-up of 5.1…
