  • Patent number: 11083495
    Abstract: An external fixation system includes first and second fixation members having first and second pluralities of mounting holes, respectively. The first and second plurality of holes are configured to receive first and second ends of a plurality of struts, each strut having a default or initial mounting position. A simulation of the correction may be performed with the struts in the default positions, but it may be determined that the correction is not achievable. Additional simulations of the correction may be performed with the ends of the struts in different mounting positions to determine if other mounting positions of the struts allow the correction to be completed. During the correction, if one of the struts reaches a maximum length, it may be disconnected and reconnected to a different mounting hole so that, after being reconnected, the strut may be further increased in length to continue the correction.

  • Patent number: 9408644
    Abstract: A length-adjustable IM nail system includes a telescoping IM nail with proximal and distal bodies. An inner magnet within the proximal body is connected to a threaded rod which, in turn, is connected to the distal body. The threaded rod passes through a threaded block which is connected to the proximal body. The position of the distal end of the threaded rod is fixed with respect to the distal body, but may rotate freely within this fixed position. An actuator is also disclosed that includes a pair of rotating magnets disposed in an angular relationship with each other and the axis of the IM nail and the patient's limb. Rotation of these outer magnets in the same direction results in rotation of the inner magnet and threaded rod and a telescoping axial movement of the threaded block and proximal body with respect to the distal body.

  • Patent number: 9408639
    Abstract: The automatically lengthening implant includes: a body defining internally an axial housing that opens out, at one end, via a mouth and that presents, at its opposite end, a narrowing of section forming an abutment face on the body; an annular plug that is fastened to the mouth of the body and that presents a stop face facing towards the abutment face; at least one rod that is engaged through the annular plug and the body; and a split ring that is mounted on the rod and that is housed in the axial housing of the body. The abutment face and the stop face present shapes that are chamfered, one reentrant and the other projecting, such that the split ring expands on being pressed against the chamfered face of projecting shape and compresses onto the rod when it is pressed against the chamfered face of reentrant shape.

  • Patent number: 9393044
    Abstract: A post that is configured to be coupled to a head of a bone fixation element that is attached to a bone part can include a post body that is elongate along a first direction and defines a proximal end and a distal end that is spaced from the proximal end along the first direction. The post body can include an internal surface that defines a socket at the distal end. The socket can be configured to receive the head of the bone fixation element. The post can further include a locking member that is disposed within the socket such that when the socket receives the head of the bone fixation element the locking member couples the post body to the bone fixation element. The post body is polyaxially pivotable relative to the head when the post body is coupled to the bone fixation element.

  • Patent number: 9381042
    Abstract: An external fixation connection rod that allows for rapid and gradual length adjustment. In some embodiments, the fixation connection rod includes an inner sleeve received within a telescopic rod to allow for rapid adjustment of an overall length of the fixation connection rod. In some embodiments, the fixation connection rod includes an adjustment mechanism to allow for gradual adjustment of the overall length of the fixation connection rod by lengthening or shortening a threaded elongated member within the inner sleeve, and the adjustment mechanism includes a first rotation member, a second rotation member, and a spring. Distal translation of the first rotation member relative to the second rotation member allows the adjustment mechanism to move from a first, locked position to a second, unlocked position, allowing the first rotation member and the second rotation member to rotate about the inner sleeve and the threaded elongated member during gradual adjustment.

  • Patent number: 9351773
    Abstract: A tool is disclosed for use in distracting and compressing fractures of any of a variety of bones. In particular, the tool has a pair of engaging arms, one arm having a hook element to engage a bone plate connected to one side of a fracture, and the other arm having at least one recess for engaging a head of a bone screw or guide wire connected to the other side of the fracture. Actuation of the tool causes the opposing bone segments of the fracture to be pushed apart or drawn together, depending on whether the tool handles are squeezed together or pulled apart. The tool may have a scissors joint that allows the ends of the tool to maintain a parallel alignment during operation, thus reducing the chances for misalignment of the bone segments during operation.

  • Patent number: 9295565
    Abstract: A method is provided for expanding an intradiscal space between opposing vertebral bodies by expanding an expandable interbody fusion device and establishing an osteoconductive path between the opposing vertebral bodies through the device during expansion. The device is expanded by introducing at least one intermediate element between an upper element and a lower element to achieve ligamentotaxis. Each of the upper element, intermediate element and lower element comprises a region of porous biocompatible material coated or impregnated with material having relatively high osteoconductive and osteoinductive properties. During and upon expansion the regions are stress loaded by the opposing vertebral bodies to promote fusion between the vertebral bodies through the device.

  • Patent number: 9168064
    Abstract: A bilateral dynamic external distractor is disclosed for the treatment of complex fracture luxations of the PIP of the hand. The distractor comprises two setscrews, one left proximal guide block, one right proximal guide block, two threaded rods, two distal guide blocks, and two optional alignment guide clips. The left and right distal guide blocks each comprise a threaded passage, and the first threaded rod extends between the right proximal guide block and the right distal guide block, and the second threaded rod extends between the left proximal guide block and the left distal guide block. Furthermore, rotation of the first and second threaded rods causes the left and right distal guide blocks to move relative to the left and right proximal guide blocks along an axis of the first and second threaded rods.

  • Patent number: 9155561
    Abstract: Described herein are external fixation systems for correcting bone deformities in adjacent bones or fragments thereof. The systems herein include first and second elongate rods that translate with respect to one another via rotation of an actuation member at an end of one of the rods. At least one housing is coupled along a length of one of the rods. The at least one housing includes at least one pin clamping member for clamping an end of a fixation pin therein. When the at least one pin clamping member is in an unlocked state, the fixation pin can rotate in polyaxial directions. When in a locked state, the angle of fixation wire with respect to the rods is set. The locked and unlocked state of the at least one pin clamping member is determined by the positing of a fixation member with respect to the housing it is coupled to.
