How is the elbow designed, and what is its function?
The elbow is the joint where three long bones meet in the middle
portion of the arm. The bone of the upper arm (humerus) meets
the inner bone of the forearm (ulna) and the outer bone of the
forearm (radius) to form a hinge joint. The radius and ulna also
meet in the elbow to allow for rotation of the forearm. The elbow
functions to move the arm like a hinge (forward and backward)
and in rotation (twisting
outward and inward).
The biceps muscle is the
major muscle that flexes
triceps muscle is the
major muscle that
extends the elbow hinge.
The outer bone of the
elbow is referred to as
the lateral epicondyle
and is a part of the humerus bone. Tendons are attached to this
area which can be injured, causing inflammation or tendinitis (lateral
epicondylitis, or "tennis elbow"). The inner portion of the elbow is a
from the muscles attach here and can be injured, causing medial
epicondylitis, "golfer's elbow." A fluid-filled sac (bursa), which
serves to reduce friction, overlies the tip of the elbow (olecranon
bursa). The elbow can be affected by inflammation of the tendons
or the bursae (plural for bursa) or conditions that affect the bones
and joints, such as fractures, arthritis, or nerve irritation. Joint pain
in the elbow can result from injury or disease involving any of these

Tennis elbow is a condition that produces severe, burning pain over
the bone at the side of the elbow. The medical term for tennis elbow
tendon that attaches muscle to the bony projection (called the
epicondyle) on the outside of the elbow.
Tennis elbow usually begins with mild pain and can worsen over time.
The pain is worsened by pressing on the affected area, by lifting
objects particularly with extension of the wrist. Using a screwdriver
can worsen the injury and cause pain. In advanced cases, even simple
movements of the elbow joint can produce pain.
While tennis elbow affects up to half of people who participate in
racquet sports, most people who develop tennis elbow do not play
racquet sports. Work activities that involve frequent use of the
forearm muscles, such as meat cutting, painting, plumbing, or
weaving are also associated with the development of tennis elbow.
