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.
摘要翻译：可扩展的椎间融合器，其包括下基板和上基板，可转动地容纳在下基板和上基板之间的插入件，以及连接到下基板和上基板的引导销，以便于插入件的旋转。插入件包括一对突起，每个突起可释放地与形成在下部和上部基板内的对应的锁定槽接合。当所述插入件相对于引导销旋转时，突起与锁定槽接合，并且下部和上部基板从折叠位置膨胀，在该折叠位置，所述下部和上部基板彼此并置并且膨胀位置，其中所述下层和上层底板彼此分开。当底板从其折叠位置膨胀到其膨胀位置时，形成在上基板上的突片连续地接合形成在下基板内的槽。

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.
