How to diagnose and differentiate posterior femoral muscle strain?

summary

Quadriceps femoris can bend hip and extend knee while running and jumping, while hamstring is its antagonist. When the strength of the hamstring muscle is less than 60% of the femoral head muscle, it is easy to damage. It shows tenderness at the back of the thigh, but does not extend below the knee joint. Sciatica usually has no tenderness and extends below the knee. How to diagnose and differentiate posterior femoral muscle strain?

How to diagnose and differentiate posterior femoral muscle strain?

Strain of the posterior thigh muscle is characterized by pain in the back of the thigh when the muscle contracts suddenly and violently (such as when the runner is blocked at the start or when the high jumper takes off from the depression), tenderness in the back of the thigh, but it does not extend to the lower part of the knee joint. Sciatica usually has no tenderness and extends below the knee. Deep thigh pain may also be due to fatigue fractures of the femur.

On physical examination, swelling of the inner thigh was seen. The tenderness is obvious. When the hip joint is passive abduction, the pain is obvious, the adductor resistance test is positive, and the "4" test is positive ("4" test, also known as Gaenslen test, is mainly used for the diagnosis of lumbosacral joint disease, sciatica, ankylosing spondylitis, etc.).

The strain of the posterior thigh muscle is usually manifested as the pain of the posterior thigh when the muscle contracts suddenly and violently (such as when the runner is blocked at the start or when the high jumper takes off from the depression). There is tenderness in the back of the thigh, but it does not extend to the lower part of the knee joint. Sciatica usually does not have tenderness and extends to the lower part of the knee. The deep pain of the thigh may also be caused by fatigue fracture of the femur, The diagnosis depends on bone scan.

matters needing attention

The diagnosis can be made according to the clinical manifestations and related examinations. The treatment of this disease is mainly symptomatic treatment, rice is helpful for acute injury. Rice treatment includes rest, ice, pressure and elevation. Other treatments include comfort therapy, stopping running and jumping, and strengthening hamstring exercises after healing.
