[Biomechanical analysis of stability of internal fixator for proximal humeral fractures].
OBJECTIVE
To review the biomechanics of internal fixators for proximal humeral fractures, and to compare the mechanical stability of various internal fixators.


METHODS
The literature concerning the biomechanics of internal fixators for proximal humeral fractures was extensively analyzed.


RESULTS
The most important things for best shoulder functional results are optimal anatomical reduction and stable fixation. At present, there are a lot of methods to treat proximal humeral fractures. Locking-plate exhibits significant mechanical stability and has many advantages over other internal fixators by biomechanical comparison.


CONCLUSIONS
Locking-plate has better fixation stability than other internal fixators and is the first choice to treat proximal humeral fractures.
