      • 14 phalanges

        • 2 for the thumb

        • 3 for each other 4 fingers

Skeletal anatomy elbow
Skeletal Anatomy - Elbow

Common injuries of the elbow
Common injuries of the Elbow

  • Several causes for a variety of athletic injuries

    • Direct trauma

    • Indirect trauma

    • Acute/Chronic stresses

  • These MOIs can result in several injuries

    • Contusions

    • Sprains

    • Strains

    • Dislocations

    • Fractures

    • Nerve involvement


  • Common injury that may involve the muscles of the forearm and subcutaneous bony prominences of the elbow

    • Usually caused by a direct blow

  • Symptoms

    • Bruising

    • Subsequent bleeding

    • Stiffness during function or

      active motion

  • Treatment

    • PRICE

      • Prevents myositisossificans

Olecranon bursitis
Olecranon Bursitis

  • Inflammation of the olecranon bursitis

    • Caused by direct blows to the olecranon process

    • Can be accompanied by infection due to the frequent abrasions that occur over the tip of the elbow

  • Treatment

    • Depends on whether infection is involved

    • Uninfected bursitis

      • Ice compresses

      • Rest

    • Anti-inflammatory meds

    • Pain meds

    • Aspiration of the bursa

Ulnar nerve contusion
Ulnar Nerve Contusion

  • Caused by a direct blow the medial epicondyle of the humerus

    • Athlete complaints of immediate pain and burning sensation down the ulnar side of the forearm to the ring and little fingers

      • Also known as hitting the “funny bone”

  • Treatment

    • None is usually necessary

Elbow strains
Elbow Strains

  • Normally occur with a sudden overload to the elbow joint

    • can acute or chronic

  • Acute Strains

    • Sudden excessive overload

    • Tenderness over the affected area

    • Pain on function or resisted motion

  • Chronic Strains

    • Result of continued overuse

    • Overuse syndrome

    • Chronic degenerative processes

  • Common areas of acute strains

    • Common flexor tendon

      • Medial epicondyle

    • Common extensor tendon

    • Tenderness

    • Localized swelling

    • Pain when repeating MOI

      • Usually relieved by bending the elbow


  • Usually caused by repetitive overload of the attached musculotendinous units

    • Occurs in the region of the medial and lateral epicondyle of the humerus

    • Called “tennis elbow” if lateral

    • Called “golfer’s elbow” if medial

    • If it occurs in younger patients, called “little leaguer elbow”

    • Can also accompany an injury to the growth plate of the epiphysis
