    ABSTRACT: Osteoporosis and its consequence of low trauma fracture represent a major health burden in aging population, because it results in increased morbidity, mortality and high health care costs. The number of hip fractures worldwide will approximately double by the year 2025 and more than triple by 2050. The aim of the study was to assess the incidence and trends of osteoporotic hip fracture in women and men aged over 50 years in polish population. Hospital records in population of 32,100 men and 39,984 women between January 1st, 2002 and December 31, 2010 with ICD-10 codes S72,0, S72,1 and S72,2 (femoral neck, intertrochanteric, subtrochanteric, inter and subtrochanteric fracture) were included in analysis. The study revealed 937 low energy hip fractures (240 in men 697 and in women). Systematic increase in rate over the study period, with the 44% in last year compared to 2002 year can be noticed. The increase was lowest in female (20.7%) than in male population (57.6%), and similarly was lowest in urban (27%) than in rural (67.7%) inhabitants. Concluding, the incidence of osteoporotic hip fracture in Polish men and women aged over 50 years is low, but the epidemiological picture is likely to change due to apparent aging of the population. Increasing trend of hip fracture incidence together with changes in age structure will result in an increased need for specialized care including several medical branches (GP, orthopedics, geriatrics, rehabilitation). Levels of evidence - IV.

    ABSTRACT: Background: Intraoperative periprosthetic femoral fracture (IPFF) is one of the most frequent complication of total hip arthroplasty (THA). This complication is a very important factor affecting rehabilitation, hospitalization time and cost of treatment. It may occur during the intramedullary reaming, removal or fixation of the stem The aim of the study was to identify risk factors of IPFF, in order to devise strategies that would minimize incidence of this complication in the future. Material/Methods: The study group consisted of patients who underwent hip surgery at the Department of Orthopaedics and Traumatology, Medical University of Silesia in Katowice between January 2002 and December 2006. We included cases of primary total hip replacement (both cemented and uncemented), hemiarthroplasties, revision THAs with exchange of at least one of the elements and the Girdlestone procedures. Results: The IPFF was diagnosed in 105 cases (101 patients), out of 1188 surgeries. We found the following risk factors for the primary THA: female gender, younger age, uncemented implant, the use of straight or revision stem, secondary osteoarthritis. For revision surgery there were: left hip surgery and implantation of revision stem. Conclusions: We hope that identification of risk factors for the intraoperative periprosthetic femoral fracture would allow orthopaedic surgeons to select the group of patients with high risk of fracture and to devise strategies that would minimize incidence of this complication in the future.

    ABSTRACT: The aim of the study was to assess fracture status in men by quantitative ultrasound measurements at the calcaneus. The diagnostic accuracy of quantitative ultrasound measurements was evaluated at baseline and follow-up. We observed 165 men (baseline age ± SD, 59.84 ± 10.6 years) recruited from an outpatient osteoporosis clinic. The mean follow-up duration was approximately 101.3 ± 35 months. There was no difference in either age or body mass index at baseline between the patients with a fracture history (n = 30) and the others (n = 135). The following fractures were identified at baseline: ankle, 15; wrist, 10; rib, 9; foot, 5; and hip, 1. The speed of sound (meters per second), broadband ultrasound attenuation (decibels per megahertz), and stiffness index (percent) were measured with a quantitative ultrasound device. The date of fracture occurrence at follow-up was defined as the final point. In the patients with a fracture history, the ultrasound variables were significantly lower than those in the rest of the group (P < .05). During the follow-up period, fractures occurred in 21 patients (wrist, 11; ankle, 5; rib, 3; hip, 1; and humerus, 1), and the ultrasound outcomes were nonsignificantly lower in the fractured men. The risk of fracture was estimated by the Cox regression analysis. A prior fracture was the only factor that significantly (4 times) increased the risk of a subsequent fracture (hazard ratio, 4.21; 95% confidence interval, 1.81-9.86; P < .001). Calcaneus ultrasound measurements can distinguish between patients with fractures and those without. In follow-up, ultrasound measurements did not indicate an increased fracture risk; a prior osteoporotic fracture was the major prognostic factor.
