This article presents a historical analysis of the origins, rise, and demise of theories of stratification (Schichtentheorien). Following their roots in the ancient metaphysical idea of the "great chain of being," Aristotle's scala naturae, the medieval "Jacob's ladder," and Leibniz's concept of the lex continua, I argue that theories of stratification represent the modern heir to the ancient cosmological idea of a harmonious, hierarchical, and unified universe. Theories of stratification reached their heyday during the interwar period within German academia, proliferating over a vast number of disciplines and rising to special prominence within personality psychology, feeding the hope for a unitary image of the world and of human beings, their biological and mental development, their social organization and cultural creations...

Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most well-established and at the same time controversial disorders to the extreme of being placed in doubt. In the first of two parts, the established position is critically reviewed, beginning with showing fallacious reasoning on which the diagnosis is based, lacking clinical proof. Similarly, a certain rhetoric and metaphysics in genetic and neurobiological research is highlighted, where, for example, a meager accumulation of data is offered as robust conclusions, and correlates and correlations as causes and bases...

OBJECTIVES: To determine whether the macroindentation test can be applied to quantitatively assess bone regeneration. METHODS: A 3.2 mm diameter transverse monocortical defect was created on the medial aspect of both proximal metaphyses of the tibia of male Unib-WH rats. For the macroindentation tests, we used 5.00 mm diameter indenters with a 3.2 mm tip. Defect testing was performed 1 to 12 weeks following the surgical procedures to compare the hardness of the newly developed tissue over the 12-week study period...

OBJECTIVES: Parallel with body growth and development, bone structure in non-adults is reorganized to achieve the particular design observed in mature individuals. We traced the changes in three-dimensional trabecular microarchitectural design during the phases of locomotor maturation to clarify how human bone adapts to mechanical demands. MATERIALS AND METHODS: Micro-CT was performed on biomechanically-relevant subregions of the proximal femur (medial, intermediate and lateral neck regions, intertrochanteric region, metaphyseal region) from early postnatal period to late childhood...

INTRODUCTION: Fronto-metaphyseal dysplasia (FMD), also called Gorlin-Cohen syndrome, is a rare syndrome initially described in 1969 by Gorlin and Cohen. Patients present skeletal dysplasia, craniofacial malformations and digit abnormalities. Craniofacial phenotype of FMD is characterized by supraorbital hyperostosis, hypertelorism, down-slanting palpebral fissures, broad nasal bridge and micrognathia. Here, we report the first adult case of craniofacial reconstruction with frontal cranioplasty in a patient with FMD...

This article presents a discussion technique that is tailored to clients needing to reorient their convictions following a critical life event. The technique has three distinctive characteristics. The client's statements are not classified into categories from conventional layer models that are designed to track the themes or content of talk. Instead, we adopt a rhetorical approach because of the fundamental metaphysical nature of conviction that this article assumes. The primary focus is on how clients talk about themselves and their convictions...

BACKGROUND: Hypophosphatasia is a rare heritable metabolic disorder characterized by defective bone and tooth mineralization accompanied by a deficiency of tissue-non-specific (liver/bone/kidney) isoenzyme of alkaline phosphatase activity, caused by a number of loss-of-function mutations in the alkaline phosphatase liver type gene. We seek to explore the clinical manifestations and identify the mutations associated with the disease in a Chinese odonto- hypophosphatasia family. RESULTS: The proband and his younger brother affected with premature loss of primary teeth at their 2-year-old...

Chronic recurrent multifocal osteomyelitis is an idiopathic nonpyogenic autoinflammatory bone disorder involving multiple sites, with clinical progression persisting for more than 6 months and which may have episodes of remission and exacerbation in the long term. It represents up to 2-5% of the cases of osteomyelitis, with an approximate incidence of up to 4/1,000,000 individuals, and average age of disease onset estimated between 8-11 years, predominantly in females. The legs are the most affected, with a predilection for metaphyseal regions along the growth plate...

We present the case of a patient who suffered a comminuted supracondylar periprosthetic femur fracture. The patient was an 86-year-old lady who suffered a minor fall at home and presented at our hospital with a right comminuted distal femur fracture around a total knee arthroplasty. The patient was submitted to a cruciate-sacrificing total knee replacement 6 years before at the same institution. Despite severe metaphyseal fragmentation and short distal fragment, the prosthesis was stable; thus, open fracture reduction and stabilization with internal fixation were performed...

Post-traumatic brachial plexopathies can occur following displaced proximal humeral fractures, causing profound functional deficits. Described here is an unusual case of a displaced proximal humeral metaphyseal fracture in a young child. The patient underwent closed reduction and serial casting, but hand weakness and forearm sensory loss persisted. Needle EMG localized the injury to the mid/proximal arm near the fracture site, resulting in damage to the posterior and medial cords of the brachial plexus with profound involvement of the radial, ulnar, and median nerves and sparing of the axillary nerve...

Metaphyseal and proximal diaphyseal fractures of the lateral column metatarsals can have problems with healing. In particular, those involving the fifth metatarsal have been associated with a high nonunion rate with nonoperative treatment. Although intramedullary screw fixation results in a high union rate, delayed healing and complications can occur. We describe an innovative technique to treat both acute and chronic injuries involving the metatarsal base from the metaphysis to the proximal diaphyseal bone of the fourth and fifth metatarsals...

We report transient proximal and distal femoral metaphyseal striations that have not previously been described in autosomal dominant brachyolmia. The pelvis/hip radiograph of a 13-year-old boy demonstrated bilaterally symmetrical proximal femoral metaphyseal vertical striations. Additional vertical striations were also observed at the distal femur and proximal tibia metaphysis. Radiography of the thoracolumbar spine demonstrated platyspondyly with irregular endplates and overfaced pedicles. TRPV4 mutations were confirmed in this patient...

Measurement and analysis of bone morphometry in 3D micro-computed tomography volumes using automated image processing and analysis improves the accuracy, consistency, reproducibility, and speed of preclinical osteological research studies. Automating segmentation and separation of individual bones in 3D micro-computed tomography volumes of murine models presents significant challenges considering partial volume effects and joints with thin spacing, i.e., 50 to 100 μm. In this paper, novel hybrid splitting filters are presented to overcome the challenge of automated bone separation...

Metacarpal fractures account for 10% to 35% of all pediatric hand fractures. Pediatric metacarpal fractures commonly occur in patients aged 13 to 16 years, with most injuries sustained during sports activities. Pseudoepiphyses can be confused with metacarpal fractures; however, a careful physical examination can help physicians distinguish the two. Thumb metacarpal base fractures that involve the physis warrant special attention. Thumb metacarpal base fractures with lateral metaphyseal fragments and pediatric Bennett fracture variants (Salter-Harris type III and type IV fractures) are unstable and require surgical management...

Hand fractures are among the most common skeletal injuries. Approximately 150,000 hand fractures occur in the United States each year. The management of hand fractures consists of reduction, immobilization, and rehabilitation to return patients to their preinjury status. Hand fractures are managed by restoring articular congruity, reducing malrotation and angulation of the fracture, and maintaining the reduction, all of which should be accomplished with minimal surgical intervention. Surgeons must assess concomitant soft-tissue injuries and respect the soft tissues during the surgical management of hand fractures...

BACKGROUND: Chronic recurrent multifocal osteomyelitis (CRMO) is an idiopathic inflammatory disease. The initial lesions are typically found in the metaphyses, generally without periosteal reaction. CASE PRESENTATION: We present a case of a 14-year-old female teenager with relapsing and remitting right iliac pain. There was no evidence of infectious organisms, neoplastic processes, or hematologic malignancy based on laboratory tests. Initial computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated atypical periosteal proliferation in the right ilium...
