Common Symptoms and Causes of Gluteus Maximus Dysfunction

Individuals dealing with pain in the buttocks can make life difficult to sit, walk, or perform simple, everyday tasks. Can understanding the anatomy, location, and function of the gluteus maximus muscle help in muscle rehabilitation and avoid potential injuries?

Gluteus Maximus

The gluteus maximus is the largest human body muscle responsible for hip extension, external rotation, adduction, and abduction, as well as the ability to stand upright.  The primary muscle extends laterally and keeps the body upright by supporting the bony pelvis and trunk. (Neto W. K. et al., 2020) When the gluteus maximus is strained, injured, or weak, it can lead to pain and inflammation.

Common symptoms can include:

• Stiffness in the buttock
• Discomfort while sitting
• Difficulty standing up from sitting
• Difficulty bending over
• Pain when walking, especially upstairs or on a hill
• Pain in the lower back and/or tailbone

Anatomy and Structure

The muscles that comprise the glutes are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus medius runs underneath the gluteus maximus, and the gluteus minimus is underneath the gluteus medius.

The gluteus maximus is one of the strongest muscles. Fibers from the muscle connect to different body parts, including the femur/thighbone and the iliotibial band, which comprises connective tissue that runs up the thigh.  The superior gluteal artery transports blood from the heart to the glutes.

Nerve Supply

The inferior gluteal nerve, part of the sacral plexus branch, innervates the maximus muscle. The sacral plexus nerves support motor and sensory function in the thighs, lower legs, feet, and pelvis. The sciatic nerve runs under the gluteus maximus, from the lower back down to the leg, and is often the cause of nerve pain in and around the area. (Carro L. P. et al., 2016) The main nerve of the perineum is the pudendal nerve, which runs under the gluteus maximus muscle.

Location

The gluteus maximus muscle defines the buttocks. It can be called a superficial muscle, sometimes referred to muscles that help provide shape. The origin of the gluteus maximus connects to the sacrum, the ilium, or the large upper part of the hip bone, the thoracolumbar fascia tissue, and the sacrotuberous ligaments attached to the posterior superior iliac spine. The gluteus maximus has a 45-degree angle from the pelvis to the buttocks and then inserts at the gluteal tuberosity of the femur and the iliotibial tract.

Variations

Sometimes, a duplicate muscle may originate from the gluteus maximus muscle in rare cases. However, it is more common that the gluteus maximus muscle fibers may be inserted into different body parts than where they are typically inserted. (Taylor, V. G., Geoffrey & Reeves, Rustin. 2015) This can cause a condition called greater trochanteric pain syndrome or GTPS. Inflammation of the gluteus medius, minimum tendons, and bursa inflammation can also cause GTPS. Individuals with GTPS will have tenderness or a pulsing feeling on the outer side of the hip and thigh when lying on the side, along with other symptoms.

Function

The gluteus maximus extends and externally rotates the hip joint, stabilizing the body. It is highly engaged during running and hiking activities. Regular walking does not typically target gluteus maximus strength training. However, the gluteus maximus promotes balance when walking and other activities by helping keep the pelvis and posture upright.

Conditions

The most common condition associated with the gluteus maximus is muscle strain, and deep gluteus maximus syndrome is another condition that can cause pain and involves the muscles.

Muscle Strain

A muscle strain can result from stretching and working the muscle too much that it becomes overstretched or tears. (Falótico G. G. et al., 2015) This can happen from not warming up or cooling down properly, repetitive use injury, and over-exercising. Alternatively, not exercising and not utilizing your gluteus maximus can weaken it, leading to lower back pain, hip pain, and stability and posture issues. (Jeong U. C. et al., 2015)

Deep Gluteus Maximus Syndrome

This syndrome causes pain in the buttocks when the sciatic nerve becomes entrapped. (Martin, H. D. et al., 2015) The location of the pain can help healthcare providers determine where the nerve is trapped. Those with deep gluteus maximus syndrome may experience various types of discomfort, including (Martin, H. D. et al., 2015)

• Numbness and tingling in the leg
• Pain when sitting
• Pain when walking
• Pain that radiates down the back and hips and into the thigh

To diagnose the condition, a healthcare provider may perform a physical examination and various tests to rule out other conditions that can cause similar symptoms.

Treatment and Rehabilitation

If there is pain in the buttocks and/or lower extremities, it’s important to consult a primary doctor, chiropractor, or physical therapist. They will evaluate the strength of the gluteus muscles to diagnose any strain or weakness. From there, they will develop a personalized treatment plan to help heal the injury, strengthen the muscles, and restore function. Treatment will include stretches once the strain is rested and improves.

• Recommendations can include taking a few days off to rest the muscle or, at the very least, stop performing the work or activity that caused the strain.
• Ice and over-the-counter medication like ibuprofen can help reduce inflammation.
• For weak gluteus maximus, a physical therapist will strengthen and retrain the muscle with a tailored program of exercises. (Jeong U. C. et al., 2015)
• Treatment for deep gluteus maximus syndrome may include conservative treatment, such as chiropractic decompression and realignment, physical therapy, medications for pain and inflammation, and injections.
• If conservative treatments do not relieve the pain, a primary healthcare provider may recommend surgery. (Martin, H. D. et al., 2015)

Working with a chiropractic physical therapy team can help individuals return to normal function and expedite healing. Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to develop a customized treatment program through an integrated approach to treating injuries and chronic pain syndromes, improving flexibility, mobility, and agility to relieve pain and help individuals return to normal activities. If other treatments are needed, Dr. Jimenez has teamed up with top surgeons, clinical specialists, medical researchers, and rehabilitation providers to provide the most effective treatments.
