Küünarliigesel

Küünarliigesel refers to the elbow joint in Estonian. It is a complex hinge joint that connects the humerus (upper arm bone) to the ulna and radius (forearm bones). This articulation allows for the flexion (bending) and extension (straightening) of the arm, as well as pronation (turning the palm downwards) and supination (turning the palm upwards) of the forearm.

The elbow joint is surrounded by a joint capsule, which is reinforced by several ligaments that provide stability. The main ligaments include the ulnar collateral ligament on the inner side and the radial collateral ligament on the outer side, along with the annular ligament which encircles the head of the radius. The muscles of the upper arm, such as the biceps and triceps, and the muscles of the forearm play crucial roles in the movement and stability of the küünarliigesel.

Injuries to the elbow joint can range from sprains and strains of the ligaments and muscles to fractures of the humerus, ulna, or radius. Conditions like tennis elbow and golfer's elbow, which are forms of tendinitis, affect the tendons that attach to the epicondyles of the humerus. Arthritis can also affect the küünarliigesel, leading to pain and stiffness. Treatment for elbow issues depends on the specific diagnosis and can include rest, physical therapy, medication, or surgery.
