- Garden III: 
*** 
- complete fracture with partial displacement;
- "if it needs a reduction, then its a type III fracture;"
- frequently there is shortening and external rotation of distal frag;
- retinaculum of Weitbrecht remains attached to, & maintains continuity between, the proximal and distal fragments;
- trabecular pattern of femoral head does not line up w/ those of acetabulum, demonstrating incomplete displacement between femoral fragments;
- management:
- closed reduction and cannulated screw fixation:
- risk of non union:
- as pointed out by Hammer (1992), 3/17 Garden 3 frx w/ transverse configuration went on to non union, whereas 6/14 frx w/ vertical configuration went on to non union;
- hemiarthroplasty
- Garden IV:
- complete fracture w/ total displacement (some authors feel that the degree of displacement between Garden III and IV fractures is not significant);
- no continuity between proximal and distal fragments;
- femoral head assumes its normal position with in the acetabulum, and therefore the trabecular patterns of the acetabulum and the femoral head are aligned;
- management:
- closed reduction and cannulated screw fixation:
- risk of non union:
- as pointed out by Hammer (1992), 0/3 Garden 4 frx w/ transverse configuration went on to non union, whereas 2/5 frx w/ vertical configuration went on to non union;
- hemiarthroplasty
