Boxers Fracture
25
Skiers Thumb (Gamekeepers)

• Acute instability of the Ulnar collateral
  ligament (UCL)
• The most common soft tissue injury of the thumb
  Metacarpophalangeal (MP) joint is UCL sprain

26
Mallet Finger (Dropped Finger)

• Mallet finger refers to a condition in which the
  end joint of a finger bends but will not
  straighten by itself. 
• Caused by sudden flexion of the distal
  interphalangeal (DIP) joint while the finger is
  in an extended position
• Often occurs from a blow to the tip of an
  extended finger
• In this situation, the joint can be pushed
  straight but will not hold that position on its
  own. 
• Traumatic avulsion of the DIP extensor tendon of
  the finger
• Most common extensor tendon injury
• Sometimes called baseball finger or drop finger
• Tendon may be stretched, completely torn, or
  associated with a bony avulsion

27
Boutonniere Deformity (Buttonhole)

• The boutonniere deformity refers to a finger
  which is bent in a particular way bent down at
  the middle joint and bent back at the end joint
• When the finger is hit or bent forcefully in just
  the wrong way, the sheet on the top of the finger
  (the central slip of tendon) tears away from its
  attachment to the top of the middle finger bone.

28
Jersey Finger (FDP TENDON AVULSION)

• Traumatic avulsion of the flexor Digitorum
  profundis (FDP) tendon
• The ring finger is most commonly affected
• DIP hyperextension (i.e. jammed finger)
• Similar to Mallet finger injury outcome
  dependant on whether flexion or hyperextension
  injury occurred
• Most commonly occurs in football when grabbing
  the jersey of an opponent who is pulling away

29
Bennett's Fracture

• A Bennett's Fracture is a fracture dislocation
  of the Metacarpal bone at the base of the thumb.
