hamstring strain
Introduction
Introduction of post-femoral muscle strain Post-femoral muscle strain is the quadriceps flexion and hip extension when the quadriceps are running, and the nematode muscle is its antagonistic muscle. When the rope muscle strength is less than 60% of the quadriceps muscle, it is easily damaged. There is tenderness on the back of the thigh, but it does not extend below the knee joint. Sciatica usually has no tenderness and extends under the knee. Because of the exhaustion of sweat, I was invaded by the evil of cold and dampness. The blood in the meridians of the human body is continuous in the circulation of the whole body, and the cold evil invades the meridians. The cold evils are converging and collecting, which can cause the meridians to be blocked, and the blood stasis is not smooth. basic knowledge The proportion of illness: the incidence rate is about 0.002%-0.003%, found in heavy physical workers Susceptible people: no specific population Mode of infection: non-infectious Complications: lumbar muscle strain
Cause
Cause of post-femoral muscle strain
Exogenous invasion (30%):
Because of the sweating and sweating, the cold and wet evils invade, the blood in the human meridians is the endless circulation of the whole body, and the cold evil invades the meridians. Cold evil condenses and attracts, but it can cause obstruction of the meridians, and the blood stasis is not smooth.
Falling servant flash (30%):
Due to violent or indirect violent trauma and excessive abduction of the thighs, the blood and blood are not running smoothly, the blood stasis is stagnant, and the meridians are blocked.
Prevention
Post-femoral muscle strain prevention
In terms of prevention, it is mainly necessary to pay attention to the care of patients to prevent complications.
1. The patient takes the supine position and presses the fingertips of the ipsilateral thumb for 1-2 minutes, so that the affected area feels sour and comfortable.
2, the patient's position as before, with the ipsilateral or contralateral thumb of the abdomen of the pain in the adductor muscles to the left and right plucked 8-10 times, in order to make local pain.
Complication
Post-femoral muscle strain complications Complications, lumbar muscle strain
Patients with this disease, due to damage to the tendons, local venous qi and blood run poorly, qi stagnation and blood stasis, occlusion of the pulse, "nothing is painful", can cause the hip and knee joints to be slightly flexed, external rotation.
As the thigh is adducted, the pain is aggravated during the outreach, and it can cause walking due to pain.
Symptom
Post-femoral muscle strain symptoms Common symptoms Thigh local swelling deformation Fatigue neuralgia quadriceps injury
The strain of the posterior femoral muscle usually manifests as pain on the posterior side of the femur when the muscle suddenly contracts severely (such as when the runner is blocked at the start or when the jumper jumps from the depression), there is tenderness on the back of the thigh, but it does not extend below the knee joint. Sciatica usually has no tenderness and extends to the knee. Deep pain in the thigh may also be caused by a femoral fatigue fracture. The diagnosis relies on bone scan.
Examine
Examination of post-femoral muscle strain
When the patient was examined for physical examination, the inner thigh was swollen. The tenderness is obvious. The pain was obvious when the hip joint was passively abducted. The special examination showed that the adductor muscle resistance test was positive, and the "4" test was positive. The "4" test (Patrick sign), also known as the Gaenslen test, is mainly used to diagnose lumbosacral joint disease, sciatica, and ankylosing spondylitis.
Diagnosis
Diagnosis and differentiation of post-femoral muscle strain
diagnosis
Diagnosis is based on clinical performance and related examinations.
Differential diagnosis
The disease needs to be identified with the following two diseases:
1. Anterior dislocation of the hip: The patient suffers from hip pain, swelling, and bulge at the groin. The femoral head can be touched in the closed hole or the upper part of the pubis. The affected limb is abducted, externally rotated, flexed and deformed, and the affected limb may be healthier. The lateral length is extended and the hip joint activity is limited. It is elastically fixed and the x-ray film can help confirm the diagnosis.
2, hip joint tuberculosis: the disease occurs in children under 15 years old, the incidence is slow, there is tenderness below the midpoint of the inguinal ligament, the longitudinal axis of the heel is positive for snoring, and the adductor muscle is caused by stimulation of the obturator nerve in the late stage., x-ray film can show that the joint space is narrow or disappear, the closed hole is slightly flat, and bone destruction can be seen in the late stage.
