Implantable devices for fixation of curved bone such as the pelvic ring pubic symphysis and acetabulum, and methods for the use of the devices are disclosed. The implantable devices are convertible between a flexible state and a rigid state, and include an elongate structure having a proximal bone interface, a main body, and a distal bone interface. In a flexible state, the devices may be inserted along, and conform to a curved pathway, and in the rigid state, the devices may support the mechanical loads required to fixate a fracture.

Knee arthroplasty instrument systems directly reference and align with the anterior distal femoral cortex and the mechanical axis of the leg. The anterior femoral resection is aligned in the same plane as the anterior distal femoral cortex. The center of the femoral head, the medial/lateral center of the distal femur, the medial/lateral center of the proximal tibia, and the second toe, medial/lateral center of the ankle, or anterior tibial spine are all aligned to the mechanical axis of the leg. Methods of using the instrument systems are disclosed.

Disclosed is an method for use of an intramedullary nail comprising a shaft having a length, a diameter, an exterior bone contacting surface, a leading (or distal) end and a trailing (or proximal) end, wherein the leading end is progressively tapered and comprises a well or cup, adapted to receive the tip of a standard K-wire, the trailing end comprises a driving fitting adapted for attachment to a driving tool for insertion of the nail into the prepared bone, the trailing end may optionally include an internal thread that can be used to secure the nail to a drill guide which can also function as an insertion handle, and the nail's shaft may also optionally be equipped with threaded and/or unthreaded cross-drilled holes for insertion of unicortical locking screws and bone screws, respectively, once the nail is placed as desired.

The present application relates to repair systems, and more particularly to fifth metatarsal repair systems and methods of use. The repair systems described herein can include a fixation device with a threaded section. The repair systems described herein can include one or more grippers designed to be deflected outward to grip the sidewalls of an intramedullary canal of the fifth metatarsal. The repair systems described herein can include an end cap. The end cap can include a fastener including thread designed to engage the threaded section of the fixation device. The end cap can include a cap designed to move relative to the fastener.

Surgical drill guides have modular configurations and are adapted to accommodate a wide range of anatomy. The surgical drill guides are adapted to be removed while leaving a guide wire in its intended location in human bone. The distal end of the drill guide acts as a safety stop for the guide wire by preventing the guide wire from penetrating too far past the far side of the bone.

An automated anchor inserter system for drilling a pilot hole and inserting an anchor. The system includes a body having a first end and a second end. An input shaft extends from the first end of the body and a guide tube extends from the second end of the body. The system also includes a first drive shaft recess and a second drive shaft recess within the body. A drill drive shaft is moveable within the input shaft and an inserter drive shaft is moveable within the second drive shaft recess. In a first configuration, the input shaft and the drill drive shaft move distally together through the first drive shaft recess and in a second configuration, the drill drive shaft moves proximally relative to the input shaft. In a third configuration, movement of the drill drive shaft moves the inserter drive shaft.

The present invention is an internal osseointegrated transfemoral amputee implant device and related methods. The device is designed to restore the enclosed nature of the bone marrow system which is disrupted by amputation, plus provide a pressure tolerant (weight-bearing) surface and mechanical anchoring for the iliotibial band.

An aiming arm system comprises an aiming arm and a guide sleeve. The aiming arm has 1) a body and a guide hole that extends through the body along a hole axis, and 2) a retention element supported relative to the body. The aiming arm is configured to be positioned such that the hole axis is aligned with a target location of an anatomical implant. The guide sleeve extends along a linear direction, and is sized to be inserted through the guide hole in the linear direction. Relative rotation between the guide sleeve and the retention element transitions the aiming arm system between an unlocked configuration whereby the guide sleeve is insertable through the guide hole, and a locked configuration whereby the retention element applies a retention force to the guide sleeve that substantially prevents the guide sleeve from moving further along the linear direction.

A system for manipulating a rotational device using a flexible guide rod with an external rod feature along its length to engage a rotational device with a complementary interior channel feature along its length. A driver having a handle and coupling element is coupled to the rotational device while the flexible guide rod extends from the handle, through the coupling element, and into the interior channel of the rotational device in order to rotate from within along the length of the device.

Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.
