The potential of locking plate with intramedullary fibular allograft to manage proximal humeral fracture with an unstable medial column.

In patients aged over 65 years with proximal humeral fractures, an unstable medial column was associated with poor clinical results owing to varus collapse. To prevent this, an intramedullary fibular allograft was used, and radiologic and clinical results were better with this approach than with a locking plate alone. Therefore, locking plate fixation using a fibular allograft is one of the possible treatments for patients with an unstable medial column.
