[Biomechanical analysis of stability of internal fixator for proximal humeral fractures]
1Department of Clinical Medicine, Medical School, Soochow University, Suzhou Jiangsu 215123, PR China.
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.
Conclusion:
Locking-plate has better fixation stability than other internal fixators and is the first choice to treat proximal humeral fractures.
