Abstract: An apparatus and methods are provided for a syndesmosis treatment assembly that includes an insertion assembly and a syndesmosis suture construct for securing a first bone against a second bone. The syndesmosis suture construct is configured to be passed through a bone hole drilled across the first bone and the second bone and cinched to press the bones together. In an embodiment, the insertion assembly includes a sleeve and a push rod for inserting the syndesmosis suture construct through the bone hole.

Abstract: A bone fusion implant is provided for treating conditions of Proximal Interphalangeal (PIP), Distal interphalangeal (DIP), and metatarsophalangeal (MTP) foot joints. The bone fusion implant may be a cortical bone allograft sized to fuse the foot joint to be treated. A proximal portion of the implant may be pressed into a hole drilled in a proximal bone portion of the foot joint, and a distal portion of the implant may be pressed into a hole drilled in a distal bone portion of the foot joint. Ramps on the proximal and distal portions facilitate press-fitting the implant into the holes in the bone portions. Side ramps ensure that the bone fusion implant remains substantially aligned with the foot joint while the distal portion is pressed into the hole into the distal bone portion. Grooves on the ramps alleviate pressure and ease inserting the implant into the holes in the bone portions.
