Anatomy of the sacroiliac joint
The sacroiliac (SI) joints represent an essential component of the pelvic girdle, playing a crucial role in upper body stability and facilitating the harmonious transfer of forces generated by the lower limbs during walking. The anatomical complexity of these joints deserves particular attention to understand their functioning and their evolution over time.
The sacroiliac joints form from an initially flat, round joint, evolving over time into an inverted “L” shaped structure. This transformation occurs with aging, creating a rearward-facing configuration, characterized by a short upper arm and a longer lower arm. This structural adaptation makes it possible to optimize the transmission of forces and effectively support body movements.
These joints are located between the articular surfaces of the sacrum and the ilium, located on the lateral aspect of the sacrum. They are an integral part of the synovial joint, where the anterior and lower third constitutes the synovial portion, with the presence of hyaline cartilage on the sacral side and fibrocartilage on the iliac side. This unique configuration contributes to shock absorption and the balanced distribution of stresses exerted on these joints.
Although sacroiliac joint movements are not directly regulated by dedicated muscles, many surrounding muscles exert an indirect influence on their function. It is important to note that the anatomical and functional complexity of these joints makes them an essential area of study for healthcare professionals, particularly in the context of musculoskeletal disorders and lower back pain.
Up and down force
When we talk about upward and downward forces at the sacroiliac joint, we are generally referring to the way in which forces are transmitted through this joint based on body movements. However, there is no purely upward or downward force in this joint; rather, there is a complex combination of forces that depend on muscular movements and actions.
- Descending Forces:
- When the body supports a load, such as when walking, running or standing, there is a transmission of forces downward through the spine and ASI to the lower extremities.
- Ascending Forces:
- Upward forces can be associated with movements where the body straightens, such as when pushing up from a seated position or bending forward to a standing position.
- Muscles and Stabilization:
- The surrounding muscles, including the gluteal muscles, core muscles, and pelvic muscles, play a crucial role in stabilizing the ASI. They help balance and distribute the forces that pass through this joint.
- Physiological Constraints:
- During pregnancy, for example, hormones such as relaxin can influence the stability of the ASI to allow greater elasticity, preparing the body for childbirth.
- Pain and Dysfunction:
- Muscle imbalances, incorrect movements, injuries, or postural problems can contribute to pain or dysfunction in the ASI. Certain disorders, such as sacroiliac syndrome, may be associated with problems in this area.
Sacroiliac movement
The sacroiliac (SI) joint is a joint located between the sacrum (the lower part of the spine) and the ilium (the pelvic bone). Movements of the sacroiliac are generally sliding, rotating, and slight tilting movements. These movements may be limited or altered if the joint is dysfunctional, such as in sacroiliac syndrome.
Movements of the sacroiliac joint include:
- Anterior and posterior tilt of the pelvis: During anterior tilt, the pelvis tilts forward, while during posterior tilt, it tilts backward. These movements are associated with the flexion and extension movements of the spine.
- Rotation: The sacroiliac joint can undergo rotational movements, meaning the sacrum can rotate slightly in relation to the ilium.
- Gliding: Sliding movements may occur, allowing the articular surfaces of the sacroiliac joint to move relative to each other.
- Compression and relaxation: Compression and relaxation forces can also play a role, particularly when transmitting loads between the spine and lower extremities.
Movement of the sacroiliac joint is generally relatively limited compared to other joints such as the hip or shoulder. However, they are essential for pelvic stability, the transmission of forces during walking and other activities, and for adapting to changes in body position.
Causes of Sacroiliac Syndrome
Let’s explore some of the possible causes of SSI in more detail:
- Trauma: Trauma, such as a fall, car accident, or sports injury, can cause damage to the sacroiliac joint. Significant forces exerted on the pelvic region can lead to instability or injury.
- Ligament instability: The ligaments surrounding the sacroiliac joint play a crucial role in its stability. Distension, overstretching, or weakness of the ligaments can lead to instability, thereby causing symptoms of SSI.
- Pregnancy: Hormonal changes during pregnancy, such as increased relaxin, can affect ligaments, softening them to make childbirth easier. However, it can also lead to instability of the sacroiliac joint, causing pain in some pregnant women.
- Arthritis: Forms of inflammatory arthritis, such as ankylosing spondylitis, can affect joints, including the sacroiliac joint. The resulting inflammation may contribute to the development of SSI.
- Leg asymmetry: Unequal leg length can create asymmetric stress on the sacroiliac joint, disrupting its balance. This asymmetry can result from a variety of conditions, including growth disorders or injuries.
- Repetitive movements: Certain occupations or activities that involve repetitive movements, such as lifting heavy objects incorrectly, can overstrain the sacroiliac joint, contributing to its dysfunction.
- Muscle dysfunction: Muscle imbalances in the pelvic region can disrupt the normal mechanics of the sacroiliac joint. Muscle weakness or uneven tension can negatively influence this joint.
- Postural stress: Poor posture, especially from prolonged periods of sitting in an inappropriate position, can place excessive pressure on the sacroiliac joint. This can lead to premature wear or imbalances.
Symptoms of Sacroiliac Syndrome
Symptoms of sacroiliac syndrome (SSI) can vary from person to person, but they generally include:
- Lower back pain: Pain is often felt in the lumbar region, usually on one side of the lower back. The pain may be localized or spread to the buttocks, hips, thigh or leg.
- Pain in the buttocks or hips: Pain may be felt in the buttocks or hips area, often on one side.
- Pain worse with certain movements: Symptoms may worsen with certain movements, such as getting up from a chair, climbing stairs, or turning the body.
- Stiffness or stuck feeling: Some individuals may feel stiffness in the sacroiliac joint, or feel like something is blocking.
- Difficulty standing or walking: Pain can make it difficult to stand for long periods of time or walk.
- Radiation of pain to the leg: In some cases, pain may radiate down the thigh or leg, sometimes mimicking symptoms similar to sciatica.
- Pain during pregnancy: In some women, SSI may be associated with pregnancy due to hormonal changes that affect the ligaments around the sacroiliac joint.
It is important to note that the symptoms of SSI can sometimes be similar to other conditions, such as a herniated disc or sciatica.
Osteopathy and treatment of sacroiliac syndrome
Here are some techniques commonly used by osteopaths to treat SSI:
- Muscle release techniques: Muscle tension around the sacroiliac joint can contribute to SSI. The osteopath uses muscle release techniques to relax tense muscles, thus promoting better mobility of the joint.
- Specific stretches: Targeted stretches may be prescribed to loosen the muscles associated with the sacroiliac joint. These stretches can be taught to the patient so that they can practice them at home.
- Mobilization techniques: The osteopath can use mobilization techniques to improve joint mobility without performing direct joint manipulation. This may be particularly beneficial for patients preferring less direct approaches.
- Postural Correction: Postural adjustments may be recommended to correct imbalances that contribute to SSI. This may include advice on posture when sitting, standing and walking.
- Specific exercises: The osteopath can prescribe specific exercises aimed at strengthening the stabilizing muscles of the sacroiliac joint. These exercises help maintain stability and prevent recurrence.
- Ergonomic advice: Lifestyle and ergonomic advice can be provided to minimize SSI risk factors. This may include recommendations on posture at work, carrying loads, etc.
It is important to note that osteopathic treatment is tailored to each patient based on their specific condition and needs.
Exercise and stretching
Here are some general exercises and stretches that may be helpful in managing SSI:
Strengthening Exercises
- Pelvic elevations:
- Lie on your back with your knees bent.
- Contract your gluteal muscles and slowly lift your hips toward the ceiling.
- Hold the position for a few seconds, then slowly lower back down.
- Repeat several times.
- Unilateral bridges:
- In the same starting position as the pelvic raises, lift one leg toward the ceiling while keeping your hips raised.
- Alternate between legs while keeping hips elevated.
- This strengthens the gluteal and stabilizer muscles.
- Knee to chest:
- Lie on your back and bring one knee toward your chest, holding it with your hands.
- Hold the position for 15-30 seconds, then release.
- Alternate between legs.
Stretching
- Stretching the piriformis muscle:
- In a seated position, cross one ankle over the opposite knee.
- Tilt your torso slightly forward while keeping your back straight.
- You should feel the stretch in the buttock of the crossed leg.
- Adductor stretch:
- Sitting with your legs apart, slowly lean forward, keeping your back straight.
- Stretch your hands forward, toward your feet.
- This stretch targets the adductors.
- Hip flexor stretch:
- From your knees, bring one leg forward, keeping your foot flat on the floor.
- Lean your pelvis forward while keeping your back straight.
- You should feel the stretch in the front of the hip.
These exercises and stretches aim to strengthen the stabilizing muscles and improve flexibility around the sacroiliac joint.
Clinical assessment of sacroiliac syndrome
Posterior pelvic pain provocation test (Östgaard):
The Posterior Pelvic Pain Provocation Test, also known as the Östgaard Test, is a clinical assessment used to assess posterior pelvic pain in individuals, particularly pregnant women. This test was developed by Norwegian researcher Stuge Östgaard.
The Posterior Pelvic Pain Provocation Test procedure generally consists of several steps:
- Patient positioning: The patient usually lies supine on an examination table.
- Hip flexion: The practitioner asks the patient to flex the hips, usually by drawing the knees toward the chest. This can be done while sitting or lying down.
- Pain assessment: During hip flexion, the practitioner observes and asks the patient about the presence of pain, particularly in the pelvis or posterior pelvic region.
- External rotation of the hips: Next, the practitioner can apply slight external rotation to the patient’s hips to see if this causes an increase in posterior pelvic pain.
- Reproducing symptoms: If the movement or position reproduces the symptoms of posterior pelvic pain, it may indicate tenderness or dysfunction at the sacroiliac joint.
The Östgaard Test is often used in the context of managing pelvic pain, particularly during pregnancy. It aims to assess the sensitivity of the sacroiliac joint and identify specific movements that may trigger or worsen pain in the patient. It is important to note that the test results should be interpreted by a qualified healthcare professional, who can then recommend appropriate interventions or treatments based on the assessment results.
Flexion, abduction and external rotation test (FABER test)
The Flexion, Abduction, and External Rotation Test, commonly known as the FABER test, is a clinical examination used to evaluate hip joint function and mobility, particularly at the hip joint and of the sacroiliac joint. This test is also known as the Patrick test or Patrick-FABER test.
Here is how the FABER test generally takes place:
- Patient positioning: The patient lies supine on an examination table.
- Flexion, abduction and external rotation of the hip: The practitioner positions the lower limb to be tested in a specific position. The knee and hip of the side to be tested are bent at a right angle, with the foot placed against the opposite knee. This position forms a figure similar to the letter “4”. The practitioner then applies light downward pressure to the knee on the side being tested, causing flexion, abduction and external rotation of the hip.
- Symptom Assessment: The patient is asked to report any discomfort, pain, or restriction of movement during application of pressure.
- Comparison with the other side: The test is often performed on both sides to allow a comparison between the right and left sides.
The FABER test is commonly used to assess hip joint and sacroiliac joint mobility. Pain or restriction of movement during the test may indicate potential problems, such as joint disorders, muscle strains, or sacroiliac joint dysfunction.
It is important to note that the FABER test is part of a comprehensive assessment and should be interpreted by a qualified healthcare professional based on the clinical context and other relevant medical information. This test is often used in the field of osteopathy, orthopedics and sports medicine.
