Where Intervention Meets Innovation

With a minimally invasive approach and fast recovery time, LINQ^® SI Joint Stabilization is the single solution for SI joint dysfunction.

What is LINQ?

The LINQ procedure provides SI joint dysfunction patients with a minimally invasive solution to combat pain. After a thorough diagnostic process, physicians can help alleviate, and in many cases eliminate, chronic pain by placing a single LINQ allograft into the SI joint. This single implant helps patients immediately regain joint stability – and with its large graft window, LINQ creates an ideal environment for long-term fusion.

STEP 01

History and Complaints of Pain

Usually, the first step to diagnose SI joint dysfunction is through a physical exam. During the exam, ask your patient about their medical history and determine whether the patient has any underlying conditions that could be causing their pain.

These risk factors from the patient can be very helpful in the identification of SI joint dysfunction.

STEP 02

Physical Examination of SI Joint

Point to Pain – Fortin Finger Test. Sitting or standing, have the patient use one finger to localize their pain. A positive test is when the patient twice identifies the painful region as within 1 cm of inferomedial (below and in the middle) to the PSIS or the dimple on the lower back above the beltline.

Palpating is when the clinician presses or touches this area to help determine SI dysfunction.

STEP 03

Provocative Testing

The Non-Invasive Identifying Process. Patients with SI joint pain typically have discomfort during provocative testing. These tests are physical examination tests that stress, or put pressure on, the SI joint(s) in various directions. Pain during these tests may signal that there’s a problem in that area. Medicare/Local Coverage Determination guidelines require 3 or more positive tests out of 5 specific provocative tests.

STEP 04

Diagnostic Injections

Sacroiliac Joint Injection:
Another Test for SI Joint Pain

Injections are one of the most accurate methods of diagnosing SI joint dysfunction. In fact, SI joint injections are considered the “gold standard” for diagnosing SI joint pain.
