Intramedullary Nail

摘要

A versatile intramedullary nail is constructed in two cooperating and optionally interlocking pieces, with a further optional annular restoration hub. The two cooperating pieces, when interlocked, approximate a long shaft, generally tubular in cross-section, with a recessed area on the male piece adapted to receive the annular restoration hub. The female piece is adapted to receive the flange of the male piece coaxially, and—unless a locking screw or bolt is inserted through the flange—the two pieces can rotate axially. Alternatively, the nail can be constructed of a single solid piece.
