The dangers of gluteus medius strain, you must not ignore

       The gluteus medius muscle is located on the deep side of the gluteus maximus, starting lateral to the iliac crest and ending at the greater trochanter of the femur. Its innervation originates from the superior gluteal nerve of L4 and 5S1. It is one of the main abductor muscles of the hip as it can abduct and internally rotate the thigh when contracted. During unipedal stance, this muscle ensures horizontal stability of the pelvis and is extremely important for maintaining normal standing and walking functions.  In daily life, the hip muscle plays an important role in body activities such as walking, squatting and bending, and it is easily damaged over time, resulting in contracture, scarring and adhesion of the local muscles, limiting activities. People are constantly in motion, and the injury site is constantly strained and stimulated, causing local congestion and swelling of the degenerated tissue, stimulating the surrounding body and blood vessels and causing symptoms.  In particular, the lateral swing of the trunk with the hip as the apex (such as in the case of foot entropion sprain, the ipsilateral hip twists to the side due to the effect of gravity and inertia) and the twisting of the waist and hip with the hip as the axis (such as throwing action) often lead to this muscle strain injury.  Damage to the gluteus medius muscle caused by drugs and mechanical stimulation during hip muscle injection should not be overlooked either. Due to the strong compensations of the gluteus maximus and vastus medialis, some of the dysfunctions caused by gluteus medius injury may not produce obvious local symptoms, and therefore, the disease is easily overlooked. However, the injury is objective. The pathological impulses generated by the gluteus medius lesion, via the L4 and 5S1 spinal nerve segments, cause pain or numbness and distension in the distal end of the ipsilateral knee joint.  Clinical manifestations: Most of the patients have a slow onset of pain and discomfort in the lumbar and hip areas, which is aggravated by exertion. In a significant number of patients, there are no local symptoms, but only the soreness and discomfort of the affected calf, or even coldness and woodiness. Pounding or massage is needed to relieve the pain. When extending the knee, the calf often has “cramp” phenomenon. Massage treatment in the calf area can relieve the symptoms. Some patients have unexplained numbness and pain or discomfort in the affected ankle, heel and bottom when walking, which can be relieved after activity. Standing for too long and walking for too long can aggravate the above symptoms and cause intermittent claudication. No obvious pressure points can be found locally. In severe cases, the calf is painful to the touch, but pressure is applied instead to feel transient comfort, affecting walking and sleep.  The clinical diagnosis is usually: calf restlessness syndrome, spinal stenosis, traumatic arthritis, etc. In some cases, only pain and discomfort in the foot and ankle, plantar numbness and swelling, and pain in the heel, metatarsal bunion, and metatarsophalangeal joints are manifested. All of the above symptoms are more dramatic at the beginning of the activity, and after the activity unfolds, the symptoms are slightly relieved, and then aggravated after exertion. Gluteus medius injury is one of the common clinical lesions.  Because the local symptoms of the lesion are often masked by the symptoms produced by its reflex zones, the disease is easily missed or misdiagnosed. Pain, soreness and discomfort in the calf, foot and ankle that are unexplained or poorly treated by conventional treatment are most often associated with injury to this muscle. The painful striae can be detected on examination of the affected gluteus medius, and the pressure point is mostly at the beginning of the iliacus lateralis.  When pressed, there may be ipsilateral hip and sacral distension and unbearable i, numbness and swelling sensation in the knee joint with distal end. If pressure is applied to the affected limb, there is no sign of nerve root irritation. In this case, the patient mostly has no pain and discomfort in the buttocks. The symptoms can be aggravated when the affected limb stands on one leg or when the thigh is forcefully abducted, and the pear-shaped muscle pull test can induce an aggravation of pain in the gluteus medius.  Treatment: Apply blood activating powder and bone catching powder externally. Or apply ointment to activate blood circulation and relieve pain, and take oral herbal medicine to activate blood circulation and remove blood stasis. Acupuncture and massage or physiotherapy.  Inject 0.5% lidocaine 5-10m1, plus prednisolone 10-1.5mg into the pressure point for local lesion injection, once every 5-7 days, 3-5 times for a course, most can be healed. For those who still do not heal, especially those with painful fascial bundles, acupuncture treatment, resection or limited gluteus medius stripping and release can be done.
