The forearm contains two primary long bones that form the skeletal framework between the elbow and the wrist. Anatomy of the Radius The radius is thinner and more compact, playing a crucial role in the rotation of the forearm.
Understanding Growth Plate Ossification in the Lower Arm Bones
The head of the radius rotates within a ligament ring, enabling the palm to face up (supination) or down (pronation). Function and Movement The coordination between the radius and ulna creates a complex system of movement.
Development and Growth Plates In children and adolescents, these two bones are separated by a layer of cartilage known as the growth plate. Common Injuries and Conditions Because the lower arm is exposed, it is susceptible to fractures, often occurring from falls onto an outstretched hand.
Understanding Growth Plate Ossification in the Lower Arm Bones
Injuries to these growth plates can affect the final length and alignment of the forearm bones. A common injury involves a fracture of the radius near the wrist, known as a Colles' fracture, while ulna fractures often occur in the middle of the shaft.
