The use of smooth and threaded pins for internal fixation is often complicated by component migration to a part of the body especially when employed about the acromioclavicuiar Joint. A case report of K-wire migration into the thoracic cavity following surgery of scapular fracture is presented. This phoenomenon occurred despite efforts to bend the lateral ends of the pins to prevent medial migration.

If pins or wires are employed even bent at the lateral ends, chinidcal and x-ray follow up should be frequent. The pins should be removed immediately on obtaining the desired therapy.
