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，从而动态地维持相邻棘突的有益对准。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。
