A Novel Surgical Approach to Coracoid-based Eosinophilic Granuloma and the Technical Trick.

The coracoid base is a very rare location for tumors. It is difficult to diagnose and approach, but easy to dismiss. In this case, the tumor (eosinophilic granuloma of the scapula) was located at the base of the coracoid, and the posterior cortex was eroded by the tumor. Accessing this lesion through the deltopectoral approach with coracoid osteotomy without penetrating the supposed tumor extending posterior soft tissue will be discussed. This approach gives a wider and safer access to the surgeon than the posterior approach. This report presents a customized solution with the deltopectoral approach, and the chevron-type osteotomy to access the coracoid base and tension band wiring to fix the osteotomy side.
