Abstract: A rotary impactor for orthopedic surgery includes an output anvil and a hammer that is capable of imparting linear and rotary force on the anvil. The anvil may be moveable on a leadscrew element to alternately generate energy in an energy storage means and to move along the leadscrew element to impact the anvil. A viscoelastic mechanism or a dampening mechanism is used to reduce the reflected force and or torque during operation of the rotary impactor. High frequency linear impacts by the impactor obviate the need for a surgeon to provide an external push force on the impactor in order to perform a successful surgical operation.

Abstract: Described herein are examples of orthopedic drill bits and methods of preparing a bone of a living being for fixation. An example method includes coupling a drive attachment of a drill bit to a mounting attachment of a driver, and placing a guide at a desired location on the bone. The guide has an opening corresponding to an area of bone to be removed. The guide provides proper positioning and alignment for drilling a hole. With the guide in place, the method further includes aligning the drill bit with the opening on the guide and drilling a hole in the bone. Once the hole is drilled, the method includes de-coupling the drill bit from the driver, and bending the drill bit at the drive attachment while the drill bit is still in the bone. In some examples, additional method steps follow preparation of the hole.

Abstract: A drill guide to facilitate drilling a hole into a bone and inserting an anchor. The drill guide includes a handle extending to a proximal end and a guide shaft extending from the handle to a distal end. A recess extends into the handle at the proximal end. The drill guide also includes a channel extending through the recess and into the guide shaft and a contact surface extending from the recess. The contact surface may be a proximal surface on a ring extending circumferentially within the recess. The contact surface may alternatively be a proximal surface on a protrusion extending from and within the recess. For example, the protrusion is a triangular protrusion extending along the recess toward the channel. The contact surface allows for the use of inserters of varying sizes within the channel of the drill guide.

Abstract: Treatment devices for sacroiliac (SI) joint hypomobility are described herein. In one example, a method of treating SI joint hypomobility involves positioning a person relative to a SI joint device that includes a resilient crest. Positioning the person relative to the SI joint device can involve aligning the resilient crest along the SI joint underneath the person. The method can also include using the SI joint device to pry open the SI joint. In another example, an SI joint device includes a body extending between a medial end and a lateral end, and the body includes a rigid protrusion. The SI joint device can also include a resilient cover extending over the rigid protrusion. The rigid protrusion and the resilient cover can define a crest for prying open the SI joint. The crest can include a concavity oriented towards the lateral end of the body, and the crest can deform towards the lateral end of the body when subjected to a load on a top of the crest.

Abstract: Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.
