Abstract: An apparatus and method are provided for a syndesmosis treatment construct configured to be placed into a cinched configuration that presses a first bone against a second bone. The syndesmosis treatment construct comprises a proximal fixator to contact the first bone and a distal fixator to contact the second bone. A first suture and a second suture are parallelly looped through the proximal fixator and oppositely looped through the distal fixator. Distal ends of the first and second sutures are fixated within a washer disposed between the proximal fixator and the first bone. Proximal ends of the first and second sutures are passed through openings in the washer and through the proximal fixator. Pulling of the proximal ends by a practitioner places the syndesmosis treatment construct into a cinched configuration. Any of various suitable suture knots may be formed so as to fixate the cinched configuration.

Abstract: An intramedullary fixation assembly for bone fixation includes a first construct. The first construct includes a first tapered screw member fixated into a subchondral bone. The first tapered screw member is aligned along a first longitudinal axis and has a first head portion comprising a first aperture and a first shaft extending from the first head portion. Moreover, the first longitudinal axis of the first tapered screw member is aligned substantially parallel to an articular surface of a bone. The first construct also includes a first lag screw member aligned along a second longitudinal axis. The first lag screw member has a first bulbous portion and a second shaft extending from the first bulbous portion, wherein the first lag screw member is coupled to the first tapered screw member, and further wherein the second longitudinal axis of the first lag screw member is aligned generally along the length of the bone.

Abstract: An intramedullary screw and fixation system for intraosseous bone fusion of the subtalar joint includes a lag screw member, a reamer for reaming an internal surface of each of the calcaneus and talus medullary canals, and targeting guide assembly for alignment with the subtalar joint. The lag screw member includes an elongated body, a first threaded portion at a first end and a bulbous portion at a second end. The targeting guide assembly receives a cutting blade in an elongated rod for reaming the articulating surfaces of the calcaneus and talus intramedullary canals, where the cutting blade is inserted through a percutaneous incision into the elongated rod.

Abstract: An intramedullary assembly for intraosseous bone fusion includes a hybrid screw member and a lag screw member. The hybrid screw member is aligned along a longitudinal axis, and includes a first shaft, a threaded portion, and a head portion having a first internal surface of a first spherical radius and a second tapered internal surface of a second radius. The first internal surface is coupled to the second internal surface to enclose a bore extending through the head portion along a bore axis. The lag screw member includes a second shaft, a bulbous portion, and a threaded portion. The lag screw member is adapted to be inserted into bore and forms an acute angle with the longitudinal axis.
