OBJECTIVE: The purpose of this study is to retrospectively evaluate a group of children affected by cerebral palsy with a recent femoral fracture, and to analyse the results and complications in relation to the treatment used. MATERIALS AND METHODS: The analysis was performed on 36 children (21 M, 15 F, 8-14 years old) with cerebral palsy (7 diplegia, 28 tetraparesis, 1 hemiplegia) with a metaphyseal or a diaphyseal femoral fracture. The patients were subdivided into two groups according to their Gross Motor Function Classification System (GMFCS) level: level 2-3 (9 patients) and level 4-5 (27 patients), evaluating the presence of complications and malunions for each group at the end of each follow up...

BACKGROUND: Subsidence remains a common complication after revision hip arthroplasty which may lead to prolonged weight-bearing restrictions, leg-length discrepancies or considerable loss of function. We evaluated the effectiveness of cement augmentation in the proximal femoral metaphysis during a revision of femoral components to prevent post-operative stem subsidence. METHODS: Forty patients were enrolled. Follow-up averaged 67.7 months (range: 24-149). Twenty-seven patients had a Paprosky type II defect and 13 had a type IIIa defect...

The aim of this study is to demonstrate the application of focused ion beam-scanning electron microscopy, FIB-SEM for revealing the three-dimensional features of osteocytic cytoplasmic processes in metaphyseal (immature) and diaphyseal (mature) trabeculae. Tibiae of eight-week-old male mice were fixed with aldehyde solution, and treated with block staining prior to FIB-SEM observation. While two-dimensional backscattered SEM images showed osteocytes' cytoplasmic processes in a fragmented fashion, three-dimensional reconstructions of FIB-SEM images demonstrated that osteocytes in primary metaphyseal trabeculae extended their cytoplasmic processes randomly, thus maintaining contact with neighboring osteocytes and osteoblasts...

What is an organ and what is an organ system? According to the 'standard' hierarchical model of physiology, each living organism comprises of organ systems including those that offer sensory and control functions (nervous system), energy accumulation (gastrointestinal system), internal dissipation (circulatory system) and mobility (musculoskeletal system). Each organ system in turn is comprised of individual organs. This taxonomy has conceptual flaws as not every organ has a single organ system function but may participate in a myriad of physiological functions...

It is a fact that in recent years requests have greatly increased to obtain estimates of the legal age of undocumented individuals alleged to be minors who have been forced to enter different European Community countries for socioeconomic reasons or due to war. Spain is one of the countries most affected by this illegal immigration because of its proximity to North Africa. Therefore, it has become necessary to develop new standards which help provide a response to the demands of the justice administration. In recent years, the Superior Justice Court has rejected several pieces of expert evidence on the grounds that the age intervals therein were not sufficiently reliable and that the radiographic techniques used to determine age were invasive, potentially causing harm to the alleged minor...

José E Burgos
This essay is a critical reappraisal of the idea of ontogenetic selection by reinforcement, according to which learning, specifically conditioning, in the individual animal is deeply analogous to phylogenetic evolution by natural selection. I focus on two general versions of this idea. The traditional Skinnerian version restricts the idea to operant conditioning and excludes Pavlovian conditioning, based on a sharp dichotomy between the two types of conditioning. The other version extends the idea to Pavlovian conditioning, based on a unified principle of reinforcement that applies to both types of conditioning, and linked to a neural-network model...

The implementing of gender ideology in the imaginary of current welfare-state societies owes much to a long process in the history of thought, which has culminated in an accommodation of post-feminist discourse. This paper sets out the epistemological principles that are present in gender ideology, as a response to both its recent and more-remote antecedents. It is furthermore framed by an urge for emancipation that began with medieval scholasticism, the latest manifestation of which lies in the post-structuralist deconstructionism that outlines the concept of queer...

Hypophosphatasia (HPP) is a rare hereditary disease characterized by defective skeletal mineralization, and with a broad severity spectrum. The perinatal forms, lethal and non-lethal, are associated with severe neonatal respiratory distress, potential seizures, hypotrophy and marked hypotonia. The diagnosis is rapidly suggested by a combination of typical radiological signs, hypercalcemia, hyperphosphatemia and low alkaline phosphatase (ALP) activity. In the infantile form, the clinical signs appear before the age of six months, but the patients usually have no or very mild signs at birth...

PURPOSE: Although volar plating of the distal radius is performed frequently, the necessity of distal bicortical fixation in the metaphyseal and epiphyseal areas of the distal radius has not been proven. This study aimed primarily to quantify the ability of unicortical distal screws to maintain operative reduction of adult distal radius fractures and secondarily to determine if unicortical screw lengths could be predicted based on anatomical measurements. METHODS: This prospective trial enrolled 75 adult patients undergoing volar locking plate fixation of a unilateral distal radius fracture at a tertiary center...

Parathyroid hormone (1-34, PTH) combined β-tricalcium phosphate (β-TCP) achieves stable bone regeneration without cell transplantation in previous studies. Recently, with the development of tissue engineering slow release technology, PTH used locally to promote bone defect healing become possible. This study by virtue of collagen with a combination of drugs and has a slow release properties, and investigated bone regeneration by β-TCP/collagen (β-TCP/COL) with the single local administration of PTH. After the creation of a rodent critical-sized femoral metaphyseal bone defect, β-TCP/COL was prepared by mixing sieved granules of β-TCP and atelocollagen for medical use, then β-TCP/COL with dripped PTH solution (1...

Postmenopausal osteoporosis is a degenerative disease caused by lack of estrogen whereby bone degeneration exceeds bone formation, resulting in loss of bone mass. Various drugs have been utilized in an attempt to ameliorate bone strength in such patients. The aim of the present study was to compare the effects of vitamin K or teriparatide alone and combined on bone metabolism and biomechanics in rats with osteoporosis. The ovaries of rats were excised to construct a rat model of osteoporosis. Rats were subjected to oral intake of vitamin K or subcutaneous injection of teriparatide or both for 8 weeks...

Background  Wrist osteoarthritis is a common disease often resulting from malunited fractures of the distal radius. The primary treatment purpose is to provide pain relief, while maintaining strength and mobility whenever possible. In a patient presenting a posttraumatic degeneration of the wrist, deciding which surgical technique, which joints to sacrifice and which to preserve is crucial to optimizing the outcome. Case Description  We describe a 10-year follow-up of an osteoarticular allograft of the distal radius proposed to treat an isolated distal radius posttraumatic degeneration...

Background  There is little published data to guide management of ulnar neck fractures associated with fractures of the distal radius. Purpose  As unplanned surgery usually reflects adverse events and this injury combination is relatively uncommon, we used a large database to study the incidence of unplanned surgeries after surgical and nonsurgical treatment of distal metaphyseal ulna fractures associated with a distal radius fracture and identify factors associated with these unplanned surgeries. Patients and Methods  We identified 277 patients with an ulnar neck fracture associated with a distal radius fracture...

Which metaphysical theories are involved-whether presupposed or implied-in Marquis' future-like-ours (FLO) argument against abortion? Vogelstein has recently argued that the supporter of the FLO argument faces a problematic dilemma; in particular, Marquis, the main supporter of the argument, seems to have to either (a) abandon diachronic universalism (DU) or (b) acquiesce and declare that contraception is morally wrong. I argue that the premises of Marquis' argument can be reasonably combined with a form of unrestricted composition and that the FLO argument is better viewed as including animalism, i...

Distal tibia fractures are reported to have a high complication rate pre-operatively as well as post-operatively, which can include open fractures, soft tissue damage, infection, malalignment, pseudarthrosis and ankle arthrosis. The operative treatment for the extra-articular distal tibia fractures is a controversial topic in the orthopaedic literature. Some of these fractures are proximal enough to be treated with an intramedullary nail while others are too distal for that. The aim of our study was to compare the results we have had with intramedullary nail (IMN) and minimally invasive plate osteosynthesis (MIPO) in distal metaphyseal (extra-articular) tibia fractures...

BACKGROUND: It is important to estimate the likelihood that a pediatric fracture is caused by osteogenesis imperfecta (OI), especially the least severe type of OI (type 1). METHODS: We reviewed records of 29,101 pediatric patients with fractures from 2003 through 2015. We included patients with closed fractures not resulting from motor vehicle accidents, gunshot wounds, nonaccidental trauma, or bone lesions. Patients with OI of any type were identified through International Classification of Diseases-9 code...

An adequate level of physical activity has a substantial effect on both mental and physical human health. Physical activity is largely dependent on the function of the musculoskeletal and articular system. One of the most frequent diseases of this system is degenerative joint disease. Due to the changing and more demanding lifestyles and patients' willingness to be involved in sports activity, the expectations of hip joint arthroplasty are becoming increasingly high. Alleviating pain ceases to be the only reason for which patients choose surgical interventions, while the expectations often include involvement in various sports...
