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.
