摘要： A swellable, resilient interspinous implant is provided that includes a swellable polymeric medium, said polymeric medium being dispersed throughout the implant, the implant being dimensioned and configured to fit between two spinous processes of two adjacent vertebrae and buttress the space between the two adjacent vertebrae. In embodiments, the implant has a first configuration of reduced size such that it can be inserted into the patient in a minimally invasive manner. Once inserted to an application point within the patient, the implant expands in size to dynamically maintain the adjacent spinous processes in beneficial alignment. Also provided is a method of making a swellable, resilient interspinous implant as described herein. Also provided is a method of treating a degenerative condition of a spine which includes creating an incision and inserting, through the incision, between two spinous processes of two adjacent vertebrae, a swellable, resilient interspinous implant as described herein.
摘要翻译： 提供了可膨胀的弹性棘突间植入物，其包括可溶胀的聚合物介质，所述聚合物介质分散在整个植入物中，所述植入物的尺寸和构造适于配合在两个相邻椎骨的两个棘突之间并且支撑两个相邻椎骨之间的空间。 在实施例中，植入物具有减小尺寸的第一构造，使得其可以以微创方式插入患者体内。 一旦插入到患者内的应用点，植入物的尺寸就会扩大，从而动态地保持邻近的棘突以有益的对准。 还提供了如本文所述的制造可溶胀，弹性棘突间植入物的方法。 还提供了一种治疗脊柱退行性病症的方法，其包括产生切口并通过切口插入两个相邻椎骨的两个棘突之间，如本文所述的可溶胀的弹性棘突间植入物。

摘要： An expandable intervertebral fusion cage that includes an inferior baseplate and a superior baseplate, an insert rotatably received between the inferior and superior baseplates, and a guide pin coupled to the inferior and superior baseplates for facilitating the rotation of the insert. The insert includes a pair of protuberances, each of which are releasably engageable with a corresponding lock groove formed within the inferior and superior baseplates. When said insert is rotated relative to the guide pin, the protuberances engage the lock grooves, and the inferior and superior baseplates expand from a collapsed position, in which said inferior and superior baseplates are juxtaposed with one another, and an expanded position, in which said inferior and superior baseplates are diverged away from one another. Tabs formed on the superior baseplate continuously engage slots formed within the inferior baseplate when the baseplates expand from their collapsed position to their expanded position.

摘要： A trapezium prosthesis is provided which includes a body having a frustocylindrical shape, the frustocylindrical shape including a frustum and an oppositely disposed planar base, the frustum being canted relative to a planar base. The prosthesis may be made of a swellable fluid absorbing polymer which imparts flexibility and/or resiliency to the prosthesis. The swellable fluid absorbing polymer may also provide the surface of the prosthesis with lubricity. In embodiments, the prosthesis has a first configuration and a second configuration, the first configuration being of reduced size relative to the second configuration. The prosthesis may also include a reinforcement member. In embodiments, the prosthesis includes a stem projecting outwardly from the frustum.

摘要： A swellable, resilient, flexible carpometacarpal (CMC) joint spacer is provided that is made of a swellable fluid absorbing polymeric medium, the spacer being dimensioned and configured to fit into the space between a natural or replacement trapezium and adjacent metacarpal bones and restore separation therebetween. In embodiments, the spacer has a cylindrical shape. In embodiments, the polymeric medium is a hydrogel. In embodiments, the spacer contains an internal reinforcement member. In embodiments, the spacer is delivered to a target site in at least a partially dehydrated state, whereupon it hydrates and expands to create positive pressure against opposing surfaces, thereby causing separation of the joint.
