Abstract
Improved tools and procedures relate to the immobilization of the sacroiliac joint for the treatment of pain associated with the joint. Kits comprise, for example, a guide element and an immobilization element of a biocompatible material with a size and shape suitable for placement within the sacroiliac joint. Suitable immobilization elements include, for example, pins, nails, screws, darts, wedges, shims and hardening material. A bioactive agent can be delivered into the joint to compliment the immobilization and promote healing. Suitable procedures can be done in a less invasive procedure through a cannula or the like.
Claims20
A method for immobilizing a sacroiliac joint comprising:
- inserting an immobilization element between the ilium bone and the sacrum bone through an extra-articular recess, thereby driving apart the ilium bone and the sacrum bone, wherein the immobilization element comprises bone material and wherein the immobilization element is delivered through a cannula.
A method for immobilizing the sacroiliac joint of a patient, the method comprising:
- placing a pin in an appropriate position using real time x-ray visualization;
- and
- inserting an immobilization element based on the pin placement between the ilium bone and the sacrum bone through an extra-articular recess, thereby driving apart the ilium bone and the sacrum bone.
A method for immobilizing a sacroiliac joint comprising:
- drilling into the sacroiliac joint between the ilium bone and the sacrum bone through a passageway provided by an extra-articular recess using a drill bit inserted within a cannula to guide the drilling to prepare the joint for placement of an immobilization element;
- and
- following drilling, inserting an immobilization element between the ilium bone and the sacrum bone through an extra-articular recess, thereby driving apart the ilium bone and the sacrum bone, wherein the immobilization element comprises bone material.
