The [lumbar triangle] is a well-defined triangular space in the posterolateral lumbar region. Also known as the inferior lumbar triangle, its boundaries are: inferior, the iliac crest; anteromedial: latissimus dorsi muscle; posterolateral: posterior border of the external oblique muscle.
What are the boundaries of superior lumbar triangle?
The superior lumbar triangle of Grynfeltt-Lesshaft is bounded superiorly by the 12th rib, the posterior lumbocostal ligament, and the serratus posterior inferior; inferiorly by the superior border of the internal oblique muscle; and posteriorly by the lateral border of the sacrospinalis.
Which muscle forms the bottom of the lumbar triangle?
This triangle is bounded posteriorly by the latissimus dorsi muscle, anteriorly by the external oblique with the iliac crest forming the base of the triangle.
How many lumbar triangles are there?
The two main areas of herniation of the lumbar region are the superior lumbar triangle (lumbocosto-abdominal triangle, triangle of Grynfeltt–Lesshaft) [2] and the inferior lumbar triangle (triangle of Petit) [3].
Is a lumbar strain serious?
While a lumbar strain may not sound like a serious injury, it can be the source of surprisingly severe pain. Lumbar strains are among the most common causes of lower back pain, and the reason for many emergency room visits each year. A lumbar strain can occur at any age, but it is most common in those in their forties.
What is the triangle of auscultation?
The triangle of auscultation is a relative thinning of the musculature of the back, situated along the medial border of the scapula which allows for improved listening to the lungs.
What is the clinical importance of the lumbar triangle?
The borders of Petit’s triangle, also known as the inferior lumbar triangle, is bounded by the latissimus dorsi posteriorly, the external oblique anteriorly, and the iliac crest inferiorly, which is the base of the triangle. The floor of the triangle is the internal oblique muscle.
Which two arteries meet within the rectus sheath?
Because of this variation and the clinical implications, it is crucial to understand the anterior and posterior laminae. The rectus sheath contains within it the superior and inferior epigastric arteries and veins, lymphatic vessels, and the thoracoabdominal nerves related to those particular structures.
What is the thoracolumbar fascia?
The thoracolumbar fascia (TLF) is a girdling structure consisting of several aponeurotic and fascial layers that separates the paraspinal muscles from the muscles of the posterior abdominal wall.
What causes muscle strain in lower back?
Lumbar muscle strain is caused when muscle fibers are abnormally stretched or torn. Lumbar sprain is caused when ligaments (the tough bands of tissue that hold bones together) are torn from their attachments. Both of these can result from a sudden injury or from gradual overuse.
Why does my lumbar vertebrae hurt?
Most commonly, mechanical issues and soft-tissue injuries are the cause of low back pain. These injuries can include damage to the intervertebral discs, compression of nerve roots, and improper movement of the spinal joints. The single most common cause of lower back pain is a torn or pulled muscle and/or ligament.
What movement does the lumbar vertebrae allow?
Biomechanics of the lumbar spine and sacrum (L4-L5 L5-S1)
The 3 movements in the spine are flexion, extension, rotation and lateral flexion.
What is in the Triangle of Doom?
The triangle of doom is a triangle bound by the vas deferens, testicular vessels, and the peritoneal fold. The importance of this triangle is in this area you can find the external iliac artery and vein. The triangle of pain is bound by the iliopubic tract, testicular vessels, and the peritoneal fold.
What is sacrospinalis muscle?
The erector spinae is not just one muscle, but a group of muscles and tendons which run more or less the length of the spine on the left and the right, from the sacrum, or sacral region, and hips to the base of the skull. They are also known as the sacrospinalis group of muscles.
What is external oblique?
The external oblique muscle is one of the outermost abdominal muscles, extending from the lower half of the ribs around and down to the pelvis.
How long does it take lumbar strain to heal?
Most people with lumbar strain/sprain symptoms improve in about 2 weeks. If symptoms continue for more than 2 weeks, additional treatment may be required.
Is walking good for lower back pain?
The simple movement of walking is one of the best things we can do for chronic lower back pain. Ten to fifteen minutes of walking twice a day will help ease lower back pain. Substitute this activity for a more vigorous type of exercise if you prefer and/or are able.
How do you fix a lumbar strain?
Treatment may include:
Rest.Ice packs and/or heat and compression applied to the back.Exercises (to strengthen the abdominal muscles)Stretching and strengthening exercises (for the lower back as it heals)Education regarding the use and wearing of appropriate protective equipment.

What causes a lumbar hernia?
Lumbar or flank hernias can be caused by weakness in the abdominal wall combined with straining and excess weight, similar to other hernias. However, it is common for lumbar hernias to be caused by trauma to the side or back of the abdominal wall.
