Three Part Fracture Dislocation:
- Discussion:
- frx dislocations may be considered an extension of
two,
three, and
four part frx classifictions;
- ultimate prognosis depends on the appearance of AVN and nonunion;
- presence of atleast one intact tuberosity usually ensures enough blood
supply to prevent AVN;
- Two Part Fracture Dislocation:
- 2 part anterior frx dislocation is associated w/ an avulsed
greater tuberosity,
or can occur thru the
surgical neck;
- in older pts w/ anterior humeral head dislocations,
massive cuff tears
are more common than avulsions;
- satisfactory reductions w/ or w/o GEA is often acheived;
- in almost all cases, closed reductions w/ no surgical rx is indicated;
- in rare cases, long head of the
biceps tendon may block
reduction, necessitating ORIF;
- Three Part Fracture Dislocations:

shoulder replacement
Acute prosthetic replacement for severe fractures of the proximal humerus.
