An intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail (without proximal or distal fixation), is a metal rod forced into the medullary cavity of a bone. IM nails have long been used to treat fractures of long bones of the body. Gerhard Küntscher is credited with the first use of this ...
Fibrous joint. In anatomy, fibrous joints are joints connected by fibrous tissue, consisting mainly of collagen. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. In the skull, the joints between the bones are called sutures. Such immovable joints are also referred to as synarthroses .
The appendicular skeleton forms during development from cartilage, by the process of endochondral ossification . The appendicular skeleton is divided into six major regions: Shoulder girdle (4 bones) - Left and right clavicle (2) and scapula (2). Arms and forearms (6 bones) - Left and right humerus (2) (arm), ulna (2) and radius (2) (forearm).
Bone canaliculus. Diagram of cross-section of bone osteons showing osteocytes and interconnecting canaliculi. Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions.
The anterior intercondylar area (or anterior intercondyloid fossa) is an area on the tibia, a bone in the lower leg. Together with the posterior intercondylar area it makes up the intercondylar area. [1] The intercondylar area is the separation between the medial and lateral condyle located toward the proximal portion of the tibia. The ...
The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. [1] The bone mass in the skeleton makes up about 14% of the total body weight (ca. 10–11 kg for an average person) and reaches maximum mass ...
An epicondyle ( / ɛpɪˈkɒndaɪl /) is a rounded eminence on a bone that lies upon a condyle ( epi-, "upon" + condyle, from a root meaning "knuckle" or "rounded articular area"). There are various epicondyles in the human skeleton, each named by its anatomic site. They include the following: Epicondyle name. Comments.
