Systems, methods, and program products for providing and administering a digital asset network of cooperative nodes with rapid transaction settlements are disclosed.

A spinal fixation construct for aligning vertebral bodies includes a bone screw, a spinal rod, a flexible member, and a fixation member. The spinal rod is disposed within a saddle portion of a housing of the bone screw, and includes an elongated body having a first end and a second end. The spinal rod is formed from a first material having a first modulus of elasticity. The flexible member is coupled to the spinal rod, and includes an elongated body having a first end portion and a second end portion. The flexible member is formed from a second material having a second modulus of elasticity that is different from the first modulus of elasticity. The fixation member includes a threaded body portion and a head portion defining a hole therethrough. A portion of the flexible member extends through the hole of the head portion.

Illustrative embodiments of orthopedic implants and methods for surgically repairing hammertoe are disclosed. According to at least one illustrative embodiment, an orthopedic implant includes a proximal segment comprising a number of spring arms forming an anchored barb at a first end of the implant, a distal segment extending between the proximal segment and a second end of the implant, and a central segment disposed between the proximal and distal segment.

A bone screw assembly includes a first body, a second body, and a thread locking assembly that may couple the first body with the second body. The first body includes a proximal portion, a distal portion that may pierce bone in response to rotation of the first body about the longitudinal axis, and a first threaded section that may engage bone. The second body defines a through hole that may receive the distal portion of the first body. The thread locking assembly includes a first thread locking section associated with the proximal portion of the first body, and a second thread locking section associated with the through hole of the second body. Either the first threaded locking section or the second threaded locking section deforms the other in response to rotation of the first threaded locking section relative to the second threaded locking section.

In described embodiments, an implant assembly includes a first implant having a body with a first end and a second end and a hollow passage extending therethrough between the first end and the second end. The first implant is sized for insertion into a first bone segment. A connector has a first end rotatably connected to the first implant at the first end of the first implant, a second end insertable into a second bone segment, and a connector body extending through the hollow passage of the first connector. A method of inserting the implant assembly is also provided.

Threaded sacro-iliac joint stabilization (e.g., fusion, fixation) implants and methods of implantation and manufacture. Some implants include a threaded distal region, an optionally threaded central region, and an optionally threaded proximal region. The distal, central, and proximal regions have lengths such that when the implant is laterally implanted across a SI joint, the distal region can be positioned in a sacrum, the central region can be positioned across an SI-joint, and the proximal region can be positioned in an ilium.

A surgical instrument having a first member engageable with a first end of a fastener having a second end configured to penetrate tissue. A second member includes an expandable member configured for engaging the first end. Systems and methods are disclosed.

A bone screw and a method for using same, the bone screw comprising an elongated shaft including a proximal end, a distal end, a leading portion, and intermediate portion and a trailing portion, the elongated shaft defining a longitudinal axis; a cannula bored completely through said elongated shaft extending from said distal end to said proximal end, the cannula aligned with said longitudinal axis; the leading portion having at least one thread; the intermediate portion being unthreaded; and the trailing portion comprising a threaded tapered head adapted engage a threaded hole at a selectable angle.

A method and system for performing bone fusion and/or securing one or more bones, such as adjacent vertebra, are disclosed. The screws include a threaded tip connected to a main shaft and a threaded outer sleeve that rotates relative to the outer shaft until locked down. Independent rotation of the threaded outer sleeve relative to the threaded distal tip allows compression or distraction to modify the gap between the vertebral bodies. The screws are passed from the inferior to superior vertebra or superior to inferior, for example, through a trans-pedicular route to avoid neurological compromise. At the same time, the path of screw insertion is oriented to reach superior or inferior vertebra. An intervertebral cage of the system is configured for lateral expansion from a nearly straight configuration to form a large footprint in the disc space. The screws and cage may be combined for improved fixation with minimal invasiveness.

This invention relates to a coupling for an orthopaedic device. Also disclosed in an orthopaedic device comprising a coupling of the invention and method for the use of the orthopaedic device. The orthopaedic device finds utility as a bolt apparatus for fixation of bones such as fractures of the femur, although it may be used in any suitable bone.
