Anatomi Radius Ulna

Anatomi Radius Ulna. The radius and the ulna constitute as the bones of the forearm The antebrachial region as it is clinically known spans the length of the region which extends roughly from elbow to wrist The radius is the lateral of the two bones which makes the ulna the medial bone of the forearm.

AnatomyFunctionAssociated ConditionsRehabilitationThe radius is a long bone one of the four types of bone in the body A long bone is a dense strong bone characterized as being longer than it is wide The shaft is known as the diaphysis and the end of a long bone is called an epiphysis The diaphysis is hollow with space inside called the medullary cavity The medullary cavity contains bone marrow The radius allows for movement of the arms and especially provides for the full range of motion of the hand and wrist3 The radius and ulna work together to provide leverage for lifting and rotation for manipulation of objects When crawling the radius also can help to provide mobility The radius provides bodyweight support when the arms are used during crawling and lifting the weight of the body such as during pushups The radius has seven muscle insertion points for the supinator biceps brachii flexor digitorum superficialis pronator teres flexor pollicis longus brachioradialis and pronator quadratus The most common medical condition of the radius is a fracture The radius while shorter and a bit thicker than the ulna is fractured more often4 It would seem that the longer ulna would have more force applied during falls or other mechanisms of injury However it is the radius that is one of the most common fractures of all age groups Weight distribution during a groundlevel fall where the patient breaks the fall with hands down puts most of the pressure on the radius It is possible to break only the radius only the ulna or both bones of the forearm Distal radial fractures are the most common type of radius bone fractures Elderly patients and pediatric patients are at more risk than young adult patients during a fall onto an outstretched hand (sometimes called a FOOSH injury)4 Elderly patients are at risk for radial head fractures which refers to the proximal end of the radius that makes up part of the elbow Pediatric patients are more likely to have noncomplete fract Treatment and rehabilitation of the radius after a fracture depends on the severity and location of the injury Treatment begins by immobilizing the fracture site The bone ends have to be placed back into the correct anatomical position (called reduction) to promote proper healing If the bone isn&#39t placed into the correct position new bone growth could result in permanent deformity6 The type of reduction and immobilization needed is based on the type and location of the fracture Severe fractures may require surgical immobilization while minor fractures might be able to be immobilized through manipulation and a cast or splint6 In many cases slings are also necessary to enhance immobilization as the patient moves through life during the weeks it takes to heal a fracture After immobilization longterm rehabilitation includes physical therapy A physical therapist will be able to teach the patient stretching and strengthening exercises that put the right amount of pressure o.

Introduction to the Radius and Ulna Bones Anatomy The radius and ulna are the bones of the forearm The forearm is the region of the upper limb that extends from the elbow to the wrist The radius bone (os radius) supports the lateral (thumb) side of the forearm and the ulna bone (os ulna) supports the medial (little finger) side.
