Abstract: A surgical device includes an body extending from a proximal end to a distal end. The distal end of the body defines a notch sized and configured to receive a reamer. A coupling assembly is supported by the body and includes a reamer guide body disposed at the distal end of the body. The reamer guide body configured to move between a first position and a second position in which the reaming guide body extends at least partially across the notch. A locking assembly is supported by the body and is configured to releasably engage the coupling assembly to maintain the reamer guide body in the second position.

Abstract: A resection guide locator includes a bone engagement portion with surfaces that are complementary to the surface topographies of a bone to be resected during surgery. A housing includes a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit to thereby position and hold the resection guide within the socket. The resection guide is maintained in a predetermined, preferred position while the surfaces are releasably locked in position on the bone. A method is disclosed for forming and using the resection guide locator.

Abstract: A minimally invasive surgical procedure for replacing a hip joint is provided. A main incision is initiated at a point being a projection of a tip of a greater trochanter and extends proximally about a distance in the range of from 1 cm to 8 cm in line with the femoral axis. An inline capsulotomy is performed, while keeping muscles and posterior capsule intact, to expose the hip joint capsule for accessing the hip joint. The femoral canal is prepared for receipt of a femoral implant. The femoral head is resected and removed out of the acetabulum. A step of acetabular preparation is performed using a retractor comprising two tip rails, each tip rail having a plurality of tines. Related tools, devices, systems and methods are also provided.

Abstract: A system for establishing an intramedullary path includes a body sized and configured to be received within a resected bone space. The body defines a first aperture that extends through the body and is sized and configured to receive a surgical tool therethrough. A first bone engaging structure extends from the body in a first direction and includes a first surface that is complementary to a surface topography of a first bone. When the first surface of the bone engaging structure engages the surface topography of the first bone to which the first surface is complementary, an axis defined by the first aperture is substantially collinear with a mechanical axis of the first bone.

Abstract: A system includes a cartridge having an elongate body extending from a first end to a second end and having a top side and a bottom side. The cartridge defines a first hole adjacent to the first end that extends through the cartridge from the bottom side to the top side. The top side of the cartridge defines a pair of parallel slots that extend perpendicular with respect to a longitudinal axis of the cartridge. Each slot of the pair of parallel slots is equidistant from a central axis defined by the first hole.

Abstract: A method includes mapping a contoured surface of at least one bone onto a digital model of a resection guide locator using a processor to create a digital model of a customized resection guide locator and manufacturing the customized resection guide locator. The customized resection guide locator includes a complementary surface of the at least one bone and a wall having a shape that is complementary to an outer profile of a resection guide and defining a pocket. A first elongate slot and at least one first hole are positioned within the pocket such that the first elongate slot aligns with a second elongate slot defined by the resection guide and the at least one first hole aligns with at least one second hole defined by the resection guide when the resection guide is received within the pocket of the customized resection guide locator.

Abstract: A method includes inserting a guide mount into a space between a talus and a tibia until a mating portion having a conformal bone engaging surface is disposed against the tibia. An instrument guide is into a cavity defined by the guide mount such that an opening defined by a superior wall of the instrument guide aligns with an opening defined by a superior wall of the guide mount. A reamer head disposed within the opening defined by the instrument guide is connected to a flexible reamer shaft that is received within a passageway defined by the instrument guide. The talus is reamed with the reamer head driven by the flexible reamer shaft.
