    Elbow wristhand and wrist2010 Elbow wristhand and wrist2010 Presentation Transcript

    • Elbow, Wrist, and Hand
    • Elbow and Forearm
      • Anatomy Involved:
        • Humerus : longest and largest bone in UE
        • Radius : lateral bone
        • Ulna: medial bone (longer than radius)
        • Group of ligaments & tendons
        • Surrounded by Capsule
          • Lubricates joint via synovial fluid
      • Hinged Joint
      • Supplied with Veins and Arteries
        • Major arteries are
          • Radial and Ulnar
    •  
    • BONES!!!
    • Injuries to the Elbow and Arm
      • Fractures
      • Dislocations or Subluxations
        • Falls on outstretched arm
        • Limb is twisted severely
      • Contusions
      • Sprains
        • Hyperextension- overextending the elbow
      • Synovitis or Bursitis
        • Repeated stressful motions
        • Direct trauma
      • Epicondylitis
        • Inflammation of epicondyle
        • “ tennis elbow” or “golfer’s elbow”
      • Biceps Brachii Rupture
        • Assist in flexion of elbow
        • Assist in rotation of the hands
        • Rupture occurs with pulling motion (gymnists, rowing, weight lifting)
    • ABILITY TO MOVE ?
      • Flexion and Extension
        • Muscles involved are above and below the elbow joint
      • Supination
        • Palm facing up (“Serving supper”)
      • Pronation
        • Palm face down
    • Injuries
      • Fractures :
      • Elbow Dislocation
    • MORE INJURIES
      • Contusion
      • Bursitis
    • More-More Injuries
      • Golfer’s Elbow
      • Tennis Elbow
    • The Wrist and Hand
    • Anatomy of Wrist and Hand
      • Wrist
        • Made up of 8 bones (carpals)
          • Tightly bound with synovial joints between them.
          • Very little movement
        • Muscles
          • Originate @ humerus
            • Flexors are anterior
            • Extensors are posterior
      • Hand
        • 5 Metacarpals and the digits (fingers)
          • Each articulate one another
          • Long bones #’d 1-5
          • 2-5 have 3 phalanges
          • 1 (thumb) only has 2 phalanges
            • Held by ligaments
        • Muscles
          • Originate @ humerus
            • Flexors are anterior
            • Extensors are posterior
      • WRIST
      • HAND
    • Carpal Bones
      • S ome L overs T ry P ositions T hey C an’t H andle
        • S cottish L ads T ake P rostitutes T o T he C aledonian H otel
        • S caphoid (a)
        • L unate (b)
        • T riquetral (c)
        • P isiform (d)
        • T rapezium (e)
        • T rapezoid (f)
        • C apitate (g)
        • H amate (h)
    • What they can do????
      • Wrist
        • Flexion/Extension
        • Radial /Ulnar Deviation
          • Shifting towards the opposite bone
      • Hand
        • Flexion/Extension
        • Adduction
          • Towards the body/part
        • Abduction
          • Away from body/part
    • All sorts of Movement
    • INJURIES
      • Fractures
      • Dislocations/subluxations
      • Contusions
      • Sprains
        • Gamekeeper’s Thumb
      • Impingement
        • Carpal Tunnel
      • Tendonitis
        • de Quervain’s – Tenosynovitis
      • Cysts (wrist)
        • Ganglion – fluid filled sac in synovial membrane that penetrates the tendon sheath
      • Mallet finger
        • Caused by direct blow to outstretched finger
        • Baseball, volleyball, basketball
        • Tearing of tendon
        • Also called “Jersey Finger”
      • Buttonhole (Boutonniere) Deformity
        • Rupture of tendon in middle phalanx
        • Caused by a force pushing the upper-joint (excessive flexion)
    • Pretty Pictures
      • Fractures: Rolando Fx
      • Dislocations: Bennett’s Fx and Dislocation
    • DID SOMEBODY SAY MMOOORE ????
      • Mallet Finger
      • Boutonniere Deformity
