Introduction

The hips and thighs have a working relationship as their jobs are to maintain stability for the legs and pelvis while supporting the upper body’s weight. These two body groups have various muscles, tendons, and nerves that have specific jobs that allow mobility to the lower body. Many athletes in multiple sports events use their thighs to exert a huge amount of power to be the best. This is due to the adductor muscles in the thighs that allow the athlete to win the event. These adductor muscles are voluminous in size and can become overstretched if the muscles have been worked out too much or injuries have caused dysfunction in the surrounding muscles, causing mobility issues. To that point, the adductor muscles will develop myofascial trigger points and cause hip and thigh pain. Today’s article looks at the two adductor muscles (Longus and Magnus), how myofascial trigger points affect the adductor muscles, and available treatments to manage hip adductor trigger points. We refer patients to certified providers who incorporate multiple methods in the lower body extremities, like thigh and hip pain treatments correlating to myofascial trigger point pain, to aid individuals dealing with pain symptoms along the adductor muscles. We encourage and appreciate patients by referring them to associated medical providers based on their diagnosis, especially when appropriate. We understand that education is an excellent solution to asking our providers complex questions at the patient’s request. Dr. Jimenez, D.C., utilizes this information as an educational service only. Disclaimer

Adductor Longus & Adductor Magnus

Have you been dealing with groin pain located near your thighs? Do you feel muscle tenderness or stiffness when stretching your inner thighs? Or have you been feeling unstable in your hips or thighs when walking? Many individuals, especially athletes and older adults, could be experiencing myofascial trigger points associated with groin pain along their adductor muscles. The thighs contain several muscles and functions that allow many people to bend and extend their knees and hips. The adductor muscles allow the legs to move inward toward one another. The adductor muscles have five muscles: magnus, brevi, longus, pectineus, and gracilis. These muscles enable functionality to the thighs and hips, and we will look at two adductor muscles in the inner thighs. The long adductor muscle is a large, fan-shaped muscle that starts from the superior aspect of the pubis bone and travels down to connect at the thigh bone. Studies reveal that the adductor longus is a long and thin muscle with many actions for the thighs, including external/lateral rotation and thigh flexion.

 

 

Now the adductor Magnus is a large triangular-shaped muscle of the inner thighs that are important for thigh and hip function and stabilizing the pelvis. Studies reveal that even though the adductor Magnus is a large muscle in the inner thighs, its primary function is to allow the thigh to move in a larger range of motion without any pain inflicted on the thigh muscles. However, the adductor muscle can succumb to various issues affecting the thighs and groin regions of the body that can be overstretched and strain the body.

 

Myofascial Trigger Points Affecting The Adductor Muscles

 

Groin pain is a multi-factorial pain issue that affects the lower limbs, and its often due to muscle strain in the inner thigh muscles. This pain increases during vigorous activities and when there is a sudden twist in the hips. When the adductor muscles suddenly change in motion when the body is active, they can be overstretched and correlate to myofascial trigger points that can affect the inner thigh and groin regions. According to “Myofascial Pain and Dysfunction,” by Dr. Travell, M.D., patients with active myofascial trigger points in the two adductor muscles (Longus and Magnus) would become frequently aware of the pain in their groin and medial thigh. When the adductor muscles have myofascial trigger points in the inner thigh, diagnosing is difficult since the individual thinks they are suffering from groin pain when the pain is in their inner thighs. To that point, studies reveal that many individuals participating in various sports would suffer from groin pain due to myofascial trigger points affecting the adductor muscles. Luckily, there are multiple treatments to reduce the pain in the adductor muscles.

Hip Adductors: Trigger Point Anatomy- Video

Have you been dealing with groin pain when you are walking? What about experiencing unquestionable thigh pain that affects your daily activities? Or does stretching your inner thigh muscles seem difficult, causing muscle tenderness? Many of these symptoms correlate with groin pain associated with myofascial trigger points affecting the adductor muscles in the inner thighs. The adductor muscles allow mobility function to the thighs and enable the hips to have a wide range of motion. When the adductor muscles are overstretched due to a sudden change of hip rotation or injury has occurred on the thighs can lead to referred pain in the groin and inner thighs and develop myofascial trigger points. The video above shows where the trigger points are located in the hip adductor muscles. The video also explains where the pain is localized in the adductor muscles and the symptoms it produces that can affect the lower body extremities. Fortunately, even though diagnosing myofascial trigger points are a bit challenging, available treatments can manage trigger points along the hip adductors.

Available Treatments To Manage Hip Adductor Trigger Points

When myofascial trigger points affect the hip adductor muscles, many individuals complain about stiffness in their inner thighs and how they feel miserable when they don’t have mobility from their thighs and hips. As stated earlier, trigger points are a bit challenging when diagnosed, but they are treatable when doctors examine patients dealing with myofascial pain in their hips and thigh muscles. Once the diagnosis is complete, doctors work with pain specialists who can locate the trigger points and devise a treatment plan to relieve the pain. Available treatments like trigger point injections can minimize the pain and reduce the chances of trigger points returning. Other available therapies like exercising or stretching, especially for the hips and thighs. Specific exercises for the hips and thigh muscles can help strengthen the adductor muscles from suffering pain and can help reduce the pain symptoms. Another treatment is applying moist heat on the hip adductor muscles to release the tension from the tight muscles and allow mobility back to the hip adductors.  

 

Conclusion

The adductor muscles work with the hips and thighs to allow a wide range of motions and extension to the knees and hips. The hips and the thighs allow stability to the lower body and support the weight to the upper body. When injuries or sudden changes start to affect the adductor muscles, it can lead to symptoms of groin pain associated with myofascial trigger points. Myofascial trigger points produce tiny nodules in the affected muscle that causes referred pain to the muscle group. When this happens, it causes the body to be dysfunctional and can affect a person’s mobility to function in the world. Luckily myofascial trigger points are treatable through various techniques and treatments that can reduce the chances of trigger points from re-occurring in the body.
