What a Ratchet! A Gripping Case Report of an Entrapped Finger with an Unyielding Wrench

Abstract

Summary: Finger entrapment with rings or ring-like objects is an uncommon possible hand emergency. In cases in which noncutting removal is ineffective, ring cutters or dental drills with carbide or diamond burs have been successfully used. However, objects composed of hard metallic alloys, such as lug nuts or wrenches, are often resistant to such equipment. In these instances, larger diameter metal cutting burrs or rasps may be more advantageous. Due to their increased size and cutting power, these tools are better suited to handle the toughness of hard metals. In this case report, we present the effective and efficient removal of a stainless steel wrench from an entrapped digit using a helicoidal rasp. Availability of this instrument within orthopedic departments may prevent the delays often described in the treatment of finger entrapment when traditional cutting equipment fails.
