摘要:
An S-shaped interspinous spacer having a pair of hooks that, upon lateral insertion between opposed spinous process, bear upon the opposed spinous processes.
摘要:
A method of correcting spinal deformity, which includes locating pharmaceutical-loaded implants adjacent to targeted spinal growth plates, and then eluting the pharmaceutical onto the growth plates. Preferably, the method involves correcting spinal deformity by simply inserting a pharmaceutical-eluting pedicle screw onto the concave side of a scoliotic curve. In some embodiments, the screw has a cannulated internal reservoir that contains a growth-inhibiting pharmaceutical (such as a tetracycline) and at least one fenestration that allows the pharmaceutical to elute onto the vertebral body growth plate.
摘要:
A formed in-place spinal implant comprising a hardenable, resorbable, bone fusion-promoting composition, wherein the implant may be rigidly connected to adjacent vertebrae until fusion occurs.
摘要:
Two techniques to minimize intervertebral disc height loss due to polymer creep following implantation of an elastomeric disc with the use of internal reinforcement are disclosed. The specific devices and methods relate to use of (i) singular or multiple internal reinforcement members to increase construct stiffness, reduce peripheral bulging and corresponding height loss; and (ii) internal elastomer fillers of various shapes which are compounded into the elastomer to share the load and constrain the elastomeric material from excessive deformations.
摘要:
The present invention provides a device for distracting two vertebral bodies and delivering a flowable material into the disc space, comprising a body having a proximal portion and a distal portion, the distal portion having a shape adapted to distract, the body also having a longitudinal bore defining a first outlet port in the distal portion, and a first injection port in the proximal portion.
摘要:
This invention relates to a method and compositions for treating pathological intervertebral discs comprising the step of delivering an agent that causes chemical crosslinking of the native molecular components of the disc. Supplemental materials which are susceptible to crosslinking by the aforementioned agent are optionally delivered to the disc in order to increase and maintain disc height.
