Percussion Sound Dull

The dull percussion sound (syn. femoral percussion sound) is a characteristic sound that is produced by percussion (tapping) with fingers on the surface of the body in the thigh area.

When percussing a healthy thigh, the sound is dull and dull. This is due to the fact that under the skin and muscles of the thigh there is a large mass of muscle tissue, which gives the sound a dull tint.

Normally, the percussion sound over the thigh should be symmetrical on the other side. Asymmetry of percussion sound may indicate pathological changes in the tissues of the thigh (edema, hematoma, tumor, etc.).

Thus, a dull, or femoral, percussion sound is an important diagnostic sign during the physical examination of the patient. Its assessment allows the doctor to judge the condition of the soft tissues and bones of the hip.

A dull percussion sound is the sound that is made when percussing the femur, namely its upper part. This sound has a low frequency and volume, which can be a sign of various diseases of the bones and joints.

Percussion sound may be dull in the following cases:

– For bone fractures, especially femur fractures. In this case, the sound will be duller and less ringing than usual.
– For joint diseases such as arthritis or tendinitis. In this case, the percussion sound will be less sonorous and more dull than usual, and may also be accompanied by pain.
– For tumors of bones or joints. In this case, the sound may be less clear or even absent.

If you hear a percussion sound that is not normal, you should consult a doctor for additional research and diagnosis.
