Flexion Type Supracondylar Frx

---

- Discussion:
        - 5-10% of all supracondylar frxs
        - occurs from fall w/ elbow flexed as it hits the ground;
        - posterior cortex fails first;
        - resulting frx has anterior displacement of the distal fragment in sagittal plane,
          and lateral/valgus displacement in coronal plane
        - fracture line courses from below upward and forward;
        - soft tissue swelling and damage are usually much less than in the
              extension type and neurovascular complications are rare;
        - ulnar nerve palsy occurs in some cases; injured by the sharp spike of
          proximal fragment
        - can use a similar classification scheme as extension type injury: types I, II, III
     
        - Type I: undisplaced or minimally displaced, cast/splint
        - Type II: inegrity of anterior cortex remains, but with anterior displacement
                  of distal fragment, reduce and cast in extension, may need pinning
        - Type III: complete displacement, usually requires open reduction and percutaneous
                    pins
