Quadratus lumborum pain is a type of lower back pain that originates from the quadratus lumborum muscle—a deep muscle in your lower back that helps stabilize the spine and support movement.
The quadratus lumborum (QL) is a rectangular muscle located in the lower back, on either side of the spine. When this muscle is strained, overworked, or injured, it can lead to pain that may radiate into the hip or groin. QL pain can result from many factors, ranging from poor posture and muscle overuse to injury or underlying spine problems. Although it is one type of lower back pain, QL pain is unique because it involves a muscle that plays a crucial role in stabilizing your torso and aiding in movements like bending and twisting.
Pathophysiology: Anatomy, Blood Supply, Nerve Supply, and Functions
Understanding the inner workings of the quadratus lumborum helps explain why pain develops and how it affects your body.
1. Anatomy and Structure
-
Location and Shape:
The quadratus lumborum is a deep, quadrilateral (four-sided) muscle found in the lower back. It stretches from the iliac crest (the top of your pelvic bone) to the lower ribs and transverse processes of the lumbar vertebrae. Its position makes it essential for lateral (side-to-side) movements and for stabilizing the lumbar spine. -
Attachments:
The muscle attaches to the lower ribs, the top of the pelvis (iliac crest), and the lumbar spine. This broad attachment helps support the spine during movement.
2. Blood Supply
- Vascular Support:
The quadratus lumborum receives blood from small branches of the lumbar arteries and other nearby vessels. A good blood supply is crucial for delivering oxygen and nutrients, which help maintain muscle health and facilitate healing if an injury occurs.
3. Nerve Supply
- Innervation:
Nerves from the lumbar plexus, including branches of the ventral rami of the lower thoracic and upper lumbar nerves, supply the quadratus lumborum. These nerves control muscle contraction and can also carry pain signals when the muscle is strained or injured.
4. Functions of the Quadratus Lumborum
-
Stabilization:
The QL is one of the key muscles that stabilize your spine during movement, helping to keep your posture upright. -
Movement:
It assists in side bending (lateral flexion) and helps rotate the trunk. When one side contracts, it can create a bending motion, while both sides contracting together can help extend the spine. -
Postural Support:
By holding the pelvis steady, the quadratus lumborum plays an important role in maintaining proper alignment and reducing strain on other back muscles.
Types of Quadratus Lumborum Pain
Quadratus lumborum pain can present in several ways, depending on the underlying cause and severity. While it may be classified by its duration or the type of injury involved, here are a few common categories:
- Acute QL Pain:
- Sudden onset often due to an injury or strain.
- Chronic QL Pain:
- Lasts for weeks or months and may result from repetitive stress, poor posture, or underlying spinal issues.
- Myofascial Pain Syndrome:
- Pain originating from trigger points (sensitive knots) in the QL muscle.
- Referred Pain:
- Pain that is felt not only in the lower back but also in the hip, groin, or buttocks.
Each type of pain may require a different approach to diagnosis and treatment.
Causes of Quadratus Lumborum Pain
Multiple factors can contribute to quadratus lumborum pain. Here are 20 common causes:
- Muscle Strain: Overuse from repetitive motions or heavy lifting.
- Poor Posture: Prolonged sitting or slouching that stresses the lower back.
- Sedentary Lifestyle: Lack of regular physical activity weakens core muscles.
- Heavy Lifting: Incorrect lifting techniques can strain the QL.
- Sudden Movements: Quick, awkward twists or bends.
