摘要： A system includes a bone anchor including a shank having a first end, a second end, a channel extending through the shank with a channel axis, and an internal advancement structure having at least a portion being closer axially to the second end than to the first end, and an elongate instrument configured to extend through the channel, with a tip portion and an external advancement structure configured to cooperate with the internal advancement structure. Engagement between the advancement structures facilitates holding of the tip portion at a first axial position relative to the bone anchor and movement of the tip portion from the first axial position towards both the first and second ends of the shank. The tip portion and the external advancement structure of the elongate instrument are insertable into and removable from the channel via the first end of the shank.

摘要： Bone anchors and surgical instruments (e.g., bone taps, drivers, etc.) are disclosed herein that include integrated guide tips. Use of these anchors or instruments can eliminate one or more of the steps in a conventional bone anchor installation procedure, improving surgical efficiency and safety. For example, a surgical instrument can include a guide projection configured for insertion through a cannulation formed in a bone anchor when the surgical instrument is coupled to the bone anchor. The surgical instrument can also include various mechanisms for adjusting the position of the guide projection relative to the bone anchor. The guide projection can replace the needle, stylet, and guidewire used in typical insertion procedures. The bone anchor can also include integrated tapping features to eliminate the need for a separate bone tap instrument. Thus, in some embodiments, targeting, tapping, and driving the bone anchor can be performed in a single step.

摘要： The current invention features a rod screw for medical application that can be configured and used to fixate fracture of bones varying in shape and dimension, and treating maladies such as scoliosis, and securing an implanted device, to tissue such as bone. This is achieved by designing a flexible rod screw with a mechanism to lock the configuration in a rigid state. In an embodiment, a bone-fracture fixation device, such as a rod screw, includes a flexible body, a plurality of flexible members, and first and second interfaces. The flexible members are disposed longitudinally within the flexible body, such that the flexible body is rigid when the flexible members are fixed into position. And the first and second interfaces are respectively coupled to the flexible body, each of at least one of the first and second interfaces including a respective at least one hole each configured to receive a respective attachment member configured to engage a bone.

摘要： An orthopedic implant system can be used to fixate two bones (e.g., to portions of a single bone) relative to each other during a surgical procedure. In some configurations, the implant system includes a staple having at least two legs separated by a bridge. The staple can include at least two couplings on either side of the bridge accessible through a top surface of the staple connectable to two corresponding coupling shafts. The coupling shafts can attach through the top surface of the staple without extending below an underside of the staple. The coupling shafts can be used to bias the at least two legs of the staple away from each other for insertion into holes formed into two bones. By attaching the coupling shafts through the top of the staple, the staple can be inserted flush with the two bones before releasing the shafts.

摘要： Disclosed is a stabilizing retractor system for orthopedic fracture repair. A backing plate is configured to support the back of a wrist or ankle. At least a first soft tissue retractor includes a first support body having a first bone engaging concavity on a first side of the body on a distal portion of the body, configured to engage a first side of a bone. A first soft tissue retracting surface is provided on a second side of the body, proximal to the bone engaging concavity. A second soft tissue retractor may be provided for engaging a second side of the bone. The retractors may be pinned to the bone, and may be radiolucent.

摘要： An apparatus and a method are provided for performing cartilage allograft implant surgeries. The apparatus comprises an allograft plug kit comprising one or more grafts configured to treat osteochondral defects in various bone joint locations in a patient's body. Each of the grafts comprises a cartilage layer coupled with a bone portion. The cartilage layer comprises a thickness selected to closely match the thickness of existing cartilage at an implant location. The bone portion comprises surface features configured to encourage the patient's bone tissue to grow into the bone portion, thereby accelerating incorporation of the graft into the patient's bone. An instrument kit comprises a multiplicity of instruments configured for implantation of the grafts into the patient's body, including at least a graft inserter, a guidewire, a reamer, and a size gauge.
