The osteotome axial twist (OAT) technique is a simple, efficient method for exposing tight, arthritic joint surfaces using an osteotome and surgical pliers. The sharp edge of a straight osteotome is used to penetrate the tight joint space with the assistance of a mallet to expose opposing articular surfaces for resection. Axial torque is applied to the osteotome with the surgical pliers, with one hand stabilizing the base of the osteotome, thereby twisting the osteotome and separating the opposing joint surfaces. The technique is also effective when used to percutaneously upgrade the depressed posterior facet of subtalar joints in selected calcaneal fractures and to gently separate calcaneal fracture fragments through an open surgical approach.
