Articulations of the humerus, radius, and ulna. [ olecranon process ]Medial collateral ligament: 3 portions, anterior, posterior, oblique

The anterior fibers are tight in extension, while the posterior fibers are tight in flexion [ beyond 90 degrees ] The posterior fibers are fan shaped and thin when compared to the anterior fibers.

lateral epicondylitis
Lateral Epicondylitis

Symptoms: Point tenderness @ lateral epicondyle; radiating pain to mid forearm and into the middle and ring finger; stiffness in elbow.

movements of elbow
Movements of elbow

Elbow: flexion - extension

Wrist: supination - pronation - ulnar and radial deviation flexion and extension

Flexion and extension originate at the humeroradial and humeroulnar joints while pronation and supination occur from the radio scaphoid (Navicular)

articulations at the wrist and the radioulnar joint at the elbow.

elbow dislocations
Elbow Dislocations

6. Dislocations (fractures of the coronoid process occur in approx. 35-40% of elbow dislocations)

Dislocations of the elbow are infrequent occurrences in intercollegiate athletics.

However, when they do occur, the are often serious injuries due to the potential for fractures and impaired distal circulation.

muscles of elbow wrist hand
Muscles of elbow, wrist, & hand
  • Biceps = primary supinator of the forearm also primary for elbow flexion.
  • Brachial, originates on the humerus, extends anteriorly across the joint and inserts into the ulna.
  • Triceps, 3 heads, Primary responsible for extension of elbow.
  • Flexor - pronator group, originates on medial side
  • Extensor - supinator group,
  • Olecranonbursae, separates the skin over the tip of the elbow from the pointed end of the ulna. [ Olecranon process ]
  • Radial - humeral bursae, lies anteriorly between the radial head and the lateral epicondyle between the muscle attachments

    • Tip of Finger Drops
    • Blood under nail
    • Swelling
  • Tx?
    • PRICE, Splint into ext., Need to refer within a week
jersey finger
Jersey Finger
  • How? – Flexor tendon rupture
    • Finger caught in jersey
  • S/S?

DIP goes into extension

PIP goes into flexion

central slip injury boutenniere deformity
Central Slip Injury / Boutenniere Deformity
  • How?
    • PIP forceabley flexed and extended @ same time

    • Tenderness over the dorsal aspect of the middle phalanx
  • Tx?
    • Splint in full extension x 6 weeks
colles fracture
Colles Fracture
  • What?
    • Distal Radial Fracture
    • Most common arm fracture
  • How?

  • S/S?
    • immediate (acute) pain,
    • tenderness, bruising, and swelling
    • Frequently, the wrist hangs in an odd or bent way (deformity).
  • TX?
    • PRICE
    • Refer to MD
    • Cast if no surgery
    • Surgery possible
smith fracture

dislocated fingers
Dislocated Fingers
  • During sports activities, a basketball or baseball may strike the tip of an outstretched finger.
  • Your finger might get caught in equipment such as a game jersey or pads.
  • You might fall onto your outstretched hand.
