Abstract: A multi-chamber balloon for a nuclear implant has an elastomeric membrane defining inner and outer chambers integral with a valve body. The valve body includes a core portion and sealing membrane for sealing the inner and outer chambers. An assembly for manufacturing the multi-chamber balloon includes a balloon mandrel which may be dip coated in a silicone dispersion to create an elastomeric membrane for the inner and outer chambers integral with the valve body.

Abstract: Described herein is an intramedullary femoral nail implant. The implant can be more easily converted to a load bearing hip replacement. Fixation of the intramedullary nail may be enhanced by injection of cement. Disclosed devices may be preferable to other types of intramedullary nails at the time of the first procedure given their characteristics of improved fixation, stability, and flexibility for potential conversion via a less complex operation.

Abstract: The present disclosure describes a spinal fixation system comprising a telescoping spinal rod, as well as methods of its use and a guide tower for use therewith. The telescoping rod can be extended after it has been inserted into the patient below the fascia, which permits it to be extended in the sub-fascial space.

Abstract: In one aspect, a surgical retractor having sliders configured to have tissue engaging members connected thereto and slider drives including operating members. The operating members are rotatable to cause the slider drives to shift the sliders relative to one another. The surgical retractor includes a coupler having a coupling configuration wherein the coupler connects the slider drives and rotation of one of the operating members causes movement of the sliders. The coupler also has a decoupling configuration wherein the coupler disconnects the slider drives and rotation of the one operating member causes movement of fewer sliders than the sliders that are moved with the coupler in the coupling configuration. The retractor has an actuator connected to the coupler and movable between a dependent slider movement position and an independent slider movement position to shift the coupler between the coupling configuration and the decoupling configuration.

Abstract: A rod group includes a plurality of first rods that has an arcuate first curve, the first rods having mutually different lengths; and a plurality of second rods that has an S-shaped second curve, the second rods having mutually different lengths. The first rods and the second rods have shapes for treatment of scoliosis by (i) guiding the postoperative apex of the thoracic kyphosis to be located at the thoracic vertebrae T6 to T8, and (ii) guiding a postoperative apex of the thoracic kyphosis to be located at a position different from a preoperative apex of the thoracic kyphosis and the second rod each have a shape extending along an anatomically normal spinal column arrangement.

Abstract: An implant and method for fixation of long bones. The implant provides rotational, longitudinal, and bending stability. The implant comprises one or more elongated members that span the intramedullary cavity of a long bone, a distal tip that expands radially relative to the long axis of the implant, and a locking mechanism at the proximal end of the implant.

Abstract: A method of preparing a metatarsophalangeal joint for fusion may involve surgically accessing the metatarsophalangeal joint and separating the metatarsal from the opposed proximal phalanx at the joint. The technique may involve preparing an end of the metatarsal and preparing an end of the opposed proximal phalanx for fusion. With or without the aid of a bone positioner, the metatarsal may be moved in one or more planes, such as the frontal and transverse planes. The proximal phalanx may also be moved in one or more planes, for example relative to the moved metatarsal. Subsequently, a bone fixation device can be applied across or through the metatarsophalangeal joint separating the metatarsal from the opposed proximal phalanx.
