Sacrotuberous Ligament Stress Test

What is a sacrotuberous ligament strain?

A sacrotuberous ligament strain occurs when this thick band of tissue connecting the sacrum to the ischium bone in the pelvis is stretched or torn due to vigorous or repetitive activities such as high jumping, golfing, gymnastics, pitching, or volleyball spiking. This injury can result in significant discomfort, often characterized by pain in the buttocks region.

The sacrotuberous ligament plays a crucial role in stabilizing the sacrum against forward tipping when pressure is applied to the spine, making it particularly susceptible to stress during activities involving excessive lower back arching.

Symptoms of this type of strain

The symptoms of a sacrotuberous ligament strain include:

• Sacroiliac joint pain: Pain around the sacroiliac joint, often felt deep in the buttocks or lower back.
• Pelvic girdle pain: The pelvic region's discomfort affects mobility and daily activities.
• Posterior sacroiliac ligament pain: Pain in the ligaments at the back of the sacroiliac joint.
• Difficulty in sacroiliac joint dysfunction: Issues with the joint's function, leading to instability or limited range of motion.

Causes of this strain

The causes of a sacrotuberous ligament strain typically involve activities that place excessive stress on the ligament. Key factors include:

• Vigorous or repetitive sports activities: Such as high jumping, golfing, gymnastics, pitching, and volleyball spiking, which involve sudden movements or repetitive motions that strain the ligament.
• Excessive arching of the lower back: Activities that require significant extension of the lower back can stress the sacrotuberous ligament, such as during certain yoga poses or weightlifting maneuvers.
• Direct trauma: A fall or impact to the buttocks or pelvis can also cause strain or partial tearing of the ligament.

What is a Sacrotuberous Ligament Stress Test?

A Sacrotuberous Ligament Stress Test is a tool in diagnosing sacroiliac joint pain and used to assess the integrity and function of the sacrotuberous ligament, which connects the sacrum to the ischial tuberosity in the pelvis. This ligament is crucial for stabilizing the sacroiliac joint and supporting the pelvic girdle during weight-bearing activities. The test is particularly useful in evaluating patients presenting with symptoms such as sacroiliac joint pain, pelvic girdle pain, and dysfunction related to the posterior sacroiliac ligaments. In the context of sacroiliac pain provocation tests discussed, healthcare providers utilize specific maneuvers to assess pain originating from the sacroiliac joint and related structures.

How is this test conducted?

The test is conducted methodically to evaluate the sacrotuberous ligament's integrity and assess for pain or dysfunction related to the sacroiliac joint. Here's a detailed step-by-step procedure:

1. Position the patient prone (lying face down) on the examination table to allow relaxation of the lower back muscles.
2. Begin by palpating the sacrotuberous ligament bilaterally to identify any tenderness, asymmetry, or localized swelling. The ligament can be palpated by locating the bony prominence of the ischial tuberosity and tracing upward toward the sacrum.
3. With the patient's hip flexed to approximately 90 degrees, passively adduct the hip across the body's midline. This maneuver specifically places stress on the sacrotuberous ligament, which is stretched and pulled during this movement.
4. Observe the patient's response during the stress maneuver. Note any signs of discomfort, pain, or reproduction of the patient's chief complaint (e.g., sacroiliac joint pain, pelvic girdle pain). Ask the patient to report any pain experienced during the maneuver, particularly over the sacroiliac joint pain site where the sacrotuberous ligament attaches to the ischial tuberosity.
5. Repeat the stress maneuver on the opposite side (left side if initially performed on the right, or vice versa) to compare responses and assess for bilateral differences. Document any discrepancies in pain perception or tenderness between the two sides.

How are the results interpreted?

The test involves comparing a patient's symptoms and physical findings with the test results. A positive test indicates that the patient's pain or discomfort over the sacrotuberous ligament area during the stress maneuver, suggesting stress and potential sacroiliac joint or pelvic girdle pain. A negative test indicates that the ligament may be functioning normally without significant strain or injury. The test also compares pain intensity and tenderness between the right and left sides, indicating potential asymmetry in ligament function or unilateral ligament strain. The test's diagnostic relevance helps differentiate between sij pain and its ligaments and pain from other sources, such as the lumbar spine.

Next steps after conducting this test

After conducting this test, healthcare practitioners need to confirm the diagnosis with imaging or diagnostic injections if needed. They would also need to plan treatment with physical therapy for pelvic girdle strengthening and pain management. They would need to educate the patients on activity modification and coordinate multidisciplinary care. Monitor progress closely and adjust interventions as necessary for optimal recovery.

Benefits of conducting this test

Conducting a sacrotuberous ligament stress test offers several benefits in clinical practice:

1. Accurate diagnosis of sacroiliac joint dysfunction: By differentiating between sacroiliac joint pain originating from ligamentous strains versus other sources such as the lumbar spine, the test aids in precise diagnosis
2. Localization of sacroiliac joint related pain: It helps pinpoint specific areas of discomfort related to the sacrotuberous ligament, posterior sacroiliac ligaments, and the posterior superior iliac spine, facilitating targeted treatment strategies
3. Assessment of ligament integrity: The test evaluates the integrity of the long posterior sacroiliac ligament and long dorsal sacroiliac ligament, crucial for stabilizing the sacroiliac joint during movement
4. Guidance for treatment planning: By documenting findings such as pain localization and tenderness, healthcare providers can tailor treatment plans to include effective pain relief measures and rehabilitative exercises
5. Enhanced patient management: It supports comprehensive patient management by providing objective data to monitor progress, adjust therapies, and optimize outcomes in cases of chronic pelvic girdle pain

Treatments for sacrotuberous ligament strains

Treatment for sacrotuberous ligament strains focuses on relieving pain, improving ligament integrity, and restoring function. Here are effective strategies:

• Physical therapy: Targeted exercises to strengthen pelvic girdle muscles and stabilize the sacroiliac joint can alleviate sacroiliac pain and improve joint function.
• Manual therapy: Techniques such as joint mobilization and soft tissue manipulation can reduce pelvic girdle tenderness points and improve the range of motion.
• Pain management: Non-steroidal anti-inflammatory drugs (NSAIDs) or pain medications may provide relief while the ligament heals.
• Sacral belt or support: Using a sacral belt can provide external support, reduce stress on the sacrotuberous ligament, and promote healing.
• Activity modification: Advising patients to avoid activities that exacerbate symptoms can prevent further strain and promote recovery.
• Injection therapies: In cases of persistent pain, corticosteroid injections or sacroiliac joint double blocks can provide targeted pain relief and reduce inflammation.
• Education and rehabilitation: Educating patients about sacroiliac joint syndrome and teaching proper body mechanics can prevent recurrence and promote long-term recovery.
