  • Publication number: 20140277194
    Abstract: The present invention is a new technology that addresses some of the deficiencies of current fracture fixation technology used in surgical procedures. It involves the use of a polymeric cored braided suture held in place by anchors implanted on each side of a fracture. The anchors must be secured into the bone while yet maintaining very high tensions in the suture during the deployment process. The polymeric cored braided suture is tensioned so as to compress the fracture and hold it in place, functioning as though it has sewn the bone fragment back together. This provides the rigid fixation of the fracture that is essential for primary healing to occur. Simultaneously, the tension preload provides compression which maintains fixation in the face of tensile and shear loads applied to the bone as a result of movement and weight bearing.

  • Patent number: 8715326
    Abstract: Embodiments of the invention are directed to a distal interphalangeal (“DIP”) fusion device for connecting a first bone of a patient to a second, adjacent bone of the patient. The device may include an anchor assembly and a compressor assembly. In another embodiment, a separate compressor base assembly is included. In yet another embodiment an access port assembly is included. The anchor assembly is rotationally coupled to one end of the compressor assembly, such that the compressor assembly may rotate about the anchor assembly within a semi-spherical zone (three degrees of rotational freedom) and translate axially (one degree of translational freedom). In an operative position, the anchor assembly is anchored in an intermediate phalanx of a digit of a patient, the compressor assembly is contained in a distal phalanx of the digit, and the distal phalanx is flexed relative to the intermediate phalanx to create a joint angle.

  • Patent number: 8690932
    Abstract: A collapsible bone screw for healing bone fragments across a bone fracture includes an externally threaded inner screw member and an externally threaded outer screw member. The inner screw member is initially screwed into an inner bone portion. An unthreaded portion of the outer screw member is movably joined to the inner screw member. The outer screw member is screwed until it gains purchase in an outer bone portion. As impaction occurs over time, the collapsible bone screw apparatus may shorten in length as the two screw members slide, telescope or otherwise axially move toward each other to shorten the overall length, thereby preventing any portion of the screw apparatus from protruding out of the bone. A bone screw kit of multiple inner and outer screw members are provided as well as a method of surgically fastening bone fragments.
