Adult Olecranon Frx:
- Discussion:
- secondary ossification centers of olecranon (bipartite olecranon or patella cubiti) should not be misdiagnosed as fractures;
- Radiology: 
- ossification center of olecranon appears at 10 yrs of age & is usually fused to proxomal ulna by age 16 yr;
- rarely these
epiphyseal plates will persist in adults (bilaterally)
-
patella buitis:
- uncommon accessory ossicle located in triceps tendon at its insertion into olecranon that may be confused with a fracture;
- references:
-
A new look at the sequential development of elbow-ossification centers in children.
- Treatment:
- undisplaced or minimally displaced frx: immobilized in long arm cast;
- markedly displaced frx: require ORIF;
- in the report by Philippe Gicquel, M.D. et al, authors presented an original fixation technique for olecranon fractures in children;
- frx site did not need to be opened;
- they used a threaded pin stabilization with adjustable lock effect;
- no significant difference was found between tension band and the threaded pin technique, whereas simple pin fixation had much poorer mechanical properties;
