The Corkscrew Technique for Removing a Fibular Strut Allograft From the Proximal Humerus

A fibular strut allograft is a reliable option for augmentation in open reduction internal fixation (ORIF) of proximal humerus fractures, but techniques to remove a fibular strut during revision shoulder arthroplasty are limited. Currently published techniques on extracting fibular strut grafts from humeral shafts include using a Midas burr, flexible osteotomes, humeral shaft osteotomy, and reaming. To our knowledge there has not been a technique that uses a corkscrew to remove the fibular strut from the proximal humerus in preparation for revision shoulder arthroplasty. This is a case report and description of a simple and reproducible technique that can be implemented in the setting of conversion from a proximal humerus lateral locking plate with fibular strut allograft to shoulder arthroplasty.
