Abstract:
Systems and methods for controlling a rotational effect on stabilizing vertebrae during and/or after deformity correction by directing reactive forces toward, on opposite sides of, and/or relatively closer to the transverse centers of rotation of the stabilizing vertebrae. The system (10) comprises a stabilizing member (12) adapted to extend between the first stabilizing vertebra and the second stabilizing vertebra, a first stabilizing anchor (14A) adapted to locate the stabilizing member with respect to the first stabilizing vertebra, a second stabilizing anchor (14B) adapted to locate the stabilizing member with respect to the second stabilizing vertebra, a correction anchor (18A) adapted to be secured to the correction vertebra and a connector (22A) secured between the stabilizing member and the correction anchor.
Abstract:
The invention relates to a textile machine with a device for recognising and correcting irregularities in the movement cycle of a component (31) operated by a driving unit (33). A device (51) detects the arrival time (t4) of the driven component (31) and corrects the starting time (t1) of the driving unit (33) within a predetermined time range (t1u-t1o) until the arrival time (t4) of the driven component (31) once again lies within a predetermined time range (t2u-t2o).
Abstract:
Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and derotating the spine to correct the spinal deformity by adjusting an effective length of the lateral coupling, and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.
Abstract:
A surgical driver for use with an implant, having a shaft with proximal and distal ends and an attachment piece with proximal and distal ends. The surgical driver including a coupling arrangement that couples the shaft and the attachment piece relative to one another. The coupling arrangement includes a recess formed at the proximal end of the attachment piece and has at least one retaining member for reversibly engaging the shaft. The coupling arrangement is adapted to accommodate interaction between the surgical driver and an implant so that variable-axis torque on the implant is minimized.
Abstract:
A spinal correction system for implantation in a patient, the system including a reciprocating adjuster and/or a resistance adjuster coupled to a stabilizing member, for example. The resistance adjuster includes a potential energy drive, a slide unit, and a resistance unit. The reciprocating adjuster includes a piston unit, a transfer unit coupled to the piston unit, and a return mechanism.
Abstract:
A spinal management system includes a stabilizing member (12) adapted to extend substantially longitudinally along a target region of a spine tending to exhibit a defective curvature and a set of stabilizing anchors (14A, 14B) adapted for fixation to vertebrae and to receive the stabilizing member to secure the stabilizing member against substantial transverse translation relative to the vertebrae. The system also includes a first correction anchor (18B) adapted for fixation to a vertebra, a second correction anchor (18A) adapted for fixation to a vertebra, and a connection (22C) between the stabilizing member and the first correction anchor and between the first and second correction anchors adapted such that when the connection is tensioned a compressive force is selectively exerted between the first and second correction anchors.
Abstract:
Systems, devices, and associated methods for correcting spinal column deformities that help minimize a number of attachment anchors utilized for correction, facilitate use of straight or contoured rods, and/or help promote a more natural, physiologic motion of the spinal column.

Abstract:
In one embodiment, a spinal stabilization apparatus (10) includes a vertebral anchor (12) having a head portion (24) and a bone attachment portion. An elongate, flexible guide is removably coupled to the head portion (24) of the vertebral anchor (12) and has a channel extending longitudinally thereof and communicating with a slot (34) in the head portion (24) of the anchor (12). An elongate cord (22) maybe received within the channel (28) to facilitate inserting and securing a spacer (20) between pairs of anchors (12) installed into adjacent vertebrae (14, 16) of a person's spine.
