What is Pelvic Ligaments Tests?
The pelvic ligament tests are the set of tests that are used for the assessment of the pelvic ligaments. There are four pelvic ligaments
- The iliolumbar ligament.
- The sacrospinous ligament & the sacroiliac ligament.
- The Sacrotuberal ligament.
The procedure of Performing The Pelvic Ligaments Tests
The examiner performs three separate procedures for the assessment of these pelvic ligaments. The most common thing about these three procedures is that the starting position of the patient remains the same. The starting position is mentioned below.
Starting Position of the Patient – The patient lies in a supine position. As explained above, it remains the same in all three procedures.
For the assessment of Iliolumbar ligament
The patient’s hip and knee are flexed. Then after that, the examiner adducts the leg to the contralateral (opposite side’s) hip.
While performing this maneuver, the examiner presses on the knee to exert axial pressure on the femur.
For the assessment of Sacrospinous and Sacroiliac ligament
The patient’s hip and knee are maximally flexed. Then after that, the examiner adducts the leg towards the contralateral (opposite side’s) shoulder. While performing this procedure, the examiner presses on the knee to exert axial pressure on the femur.
For the assessment of Sacrotuberal ligament
The patient’s hip and knee are maximally flexed. Then after that, the examiner moves the leg towards the ipsilateral (same side) shoulder.
Stretching pain occurring within a few seconds can signify that there is functional shortening & excessive stress on the ligaments. However, it can also happen in a motion-restricted sacroiliac joint or hypermobile joint.
Pain caused by stretching the iliolumbar ligament is referred to the inguinal region (the differential diagnosis includes a hip disorder).
Pain caused by stretching the sacroiliac and sacrospinous ligament is felt within the S1 dermatome from a point posterolateral to the hip as far as the knee.
The pain caused by stretching the sacrotuberal ligament radiates into the posterior side of the thigh.
