Gluteal region

Sacroiliac joints The sacroiliac joints link the pelvis and lower spine. These two joints are made up of the bony structure above the tailbone, known as the sacrum, and the top part of the pelvis, known as the ilium. The sacroiliac joints support the weight of the upper body when standing. Sacroiliitis (say-kroe-il-e-I-tis) is a painful condition that affects one or both sacroiliac joints. These joints sit where the lower spine and pelvis meet. Sacroiliitis can cause pain and stiffness in the buttocks or lower back, and the pain might go down one or both legs. Standing or sitting for a long time or climbing stairs can make the pain worse. Symptoms The pain of sacroiliitis most often occurs in the buttocks and lower back. It also can affect the legs, groin and even the feet. The pain can improve with movement. The following can make sacroiliitis pain worse: • Sleeping or sitting for a long time. • Standing a long time. • Having more weight on one leg than the other. • Stair climbing. • Running. • Taking large steps when moving forward. Causes Causes for sacroiliac joint issues include: • Injury. A sudden impact, such as a motor vehicle accident or a fall, can damage the sacroiliac joints. • Arthritis. Wear-and-tear arthritis, also known as osteoarthritis, can occur in sacroiliac joints. So can a type of arthritis that affects the spine, known as ankylosing spondylitis. • Pregnancy. The sacroiliac joints loosen and stretch for childbirth. The added weight and changed way of ...

In the gluteal region, the thickness of adipose tissue varies throughout the person.1,3 For clinical IM applications, 1 to 1.5 inch (25-38 mm) IM injection needles are used, and the standard 32 mm IM injection needles reach a penetration depth of about 30 mm in clinical practice, penetrating into the muscle at least 5 mm to achieve a successful IM injection. An 8 years old boy presented with multiple, large, painful nonhealing ulcers over trunk, both legs and gluteal region. The patient was alright 5 months back when he developed vesicular lesions over the right gluteal region and right thigh that enlarged to form bullae and later ruptured leaving behind large ulcerations that were painful restricting his mobility.

• 1 The Superficial Muscles • 1.1 Clinical Relevance: Damage to the Superior Gluteal Nerve • 2 The Deep Muscles • 2.1 Clinical Relevance: Landmark of the Gluteal Region The gluteal region is an anatomical area located posteriorly to the pelvic girdle, at the proximal end of the femur. The muscles in this region move the lower limb at the hip joint. The muscles of the gluteal region can be broadly divided into two groups: • Superficial abductors and extenders – group of large muscles that abduct and extend the femur. Includes the gluteus maximus, gluteus medius, gluteus minimus and tensor fascia lata. • Deep lateral rotators – group of smaller muscles that mainly act to laterally rotate the femur. Includes the quadratus femoris, piriformis, gemellus superior, gemellus inferior and obturator internus. The arterial supply to these muscles is mostly via the superior and inferior gluteal arteries – branches of the internal iliac artery. Venous drainage follows the arterial supply. In this article, we shall examine the two groups of gluteal muscles – their attachments, innervations and actions. We shall also look at the clinical consequence of gluteal muscle disorders. The Superficial Muscles The superficial muscles in the gluteal region consist of the three glutei and the tensor fascia lata. They mainly act to abduct and extend the lower limb at the hip joint. Gluteus Maximus The gluteus maximus is the largest of the gluteal muscles. It is also the most superficial, producing t...

Gluteal Tendinopathy (GT), often referred to as Greater Trochanter Pain Syndrome (GTPS), can affect both athletes and those who are inactive. The disorder occurs when a tendinopathy, or a disorder with a tendon, develops in one of the gluteal muscles or Greater Trochanter. When this occurs, the tendons can become inflamed, making it very painful to sit, stand, or walk. The gluteal muscles are a collection of three muscles that make up the gluteal region usually known as the buttocks. Here are a few ways to recognize and alleviate some of the symptoms related to gluteal tendinopathy. Causes of Gluteal Tendinopathy Gluteal tendinopathy can develop due to many different causes such as gluteal muscle overuse from frequent running or jogging, as well as muscle fatigue that creates an imbalance in the gluteal muscles that provide hip support. However, most cases of gluteal tendinopathy stem from tiny tears in the tendon tissue. Tears can often occur if the muscle is too weak or isn’t strong enough to support the body, explaining why gluteal tendinopathy commonly occurs in those suffering from obesity. Gluteal Tendinopathy Symptoms One of the most common symptoms of gluteal tendinopathy is debilitating hip pain, especially in the outer hips and lateral thigh. Those suffering from the disorder may also notice swelling or redness around the hips. Treatments for Gluteal Tendinopathy If you are suffering from gluteal tendinopathy, then it is important to give your gluteal muscles tim...

The gluteal region and posterior thigh contains an abundance of large and small muscles, and coursing through these muscles is a vast network of nerves and vessels. These nerves mainly originate from the Ok, so let’s start with the nerves of the gluteal region and posterior thigh. Most nerves of the However, out of all the resulting nerves, the gluteal region and posterior thigh is only supplied by the cluneal nerves, superior and Let's start off with the cluneal nerves which innervate the skin of the gluteal region. The superior cluneal nerves arise from L1-L3, and supply the skin of the superior buttock. The middle cluneal nerve arises from S1-S3 and supplies skin over the And finally the inferior cluneal nerve is a branch of the posterior cutaneous nerve of the thigh from S2-S3 and supplies skin over the inferior half of the buttocks as far as the greater trochanter. Next, there’s the The nerve courses laterally between the It then goes on to innervate the the Sitemap USMLE® is a joint program of the Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME).

The bony component of the gluteal (buttocks) region consists of two pelvic bones (os coxae) joined anteriorly by the symphysis pubis and posteriorly by the sacrum. Each os coxa is composed of three fused bones: ilium, ischium, and pubis. The bones of the gluteal region contain foramina (notches), which serve as conduits for nerves and blood vessels that travel between the pelvis, gluteal region, perineum, and lower limb. Muscles of the gluteal region primarily act on...
