The Ideberg classification is a system of categorizing scapula fractures involving the glenoid fossa. Those that occur in the neck are usually parallel to the glenoid fossa. Its counterpart in the pectoral girdle is the glenoid fossa. It is also referred to as the glenoid fossa in dental literature. The glenoid cavity or glenoid fossa of scapula is a part of the shoulder. Above the glenoid fossa is a raised area known as the supraglenoid buttress.
