In agreement with the theory of McKee and Jupiter [ 15], who considered securing the Trochlea between two bony columns to be most important for stable fixation, the proposed technique unites these columns to establish a triangular configuration for superior load bearing.
Early mobilization of the PIP along with traction and stable fixation offer the most favorable functional outcomes.
Serin et al. [ 26] showed that four levels posterior fixation is superior to two levels posterior fixation and a four levels fixation plus offset hook is the most stable.
Most metallic shells in both groups showed stable fixation.
The most important factors in obtaining fracture healing are anatomical reduction, stable fixation and adequate blood supply.
We also understand that stable fixation is sometimes difficult to achieve but most of capitellar fractures can be fixed reasonably well to allow early mobilization (Mighell et al. 2006, Ruchelsman et al. 2008, Singh et al. 2009).
Half of them received stable fixation with a newly custom-designed external fixator (FSF, the group of fracture with stable fixation), while the rest received no fixation (FNF, the group of fracture with no fixation).
It relies on the periarticular ring construct for stable fixation of the tibial condyles and monolateral fixator for fixation on the shaft to provide a stable fixation block.
