Peroneal Nerve Compression (Trap)

The peroneal nerve is mostly compressed at the lateral side of the knee between the leg bone called the fibula and the muscles and ligaments. It is characterized by the weakness of the muscles called the foot dorsiflexors, which lift the foot from the ankle. The patient has to drag his ankle because he cannot keep it straight while walking. There is also numbness on the feet. For this reason, it can sometimes be confused with nerve root compression due to herniated disc.

Peroneal nerve entrapments; prolonged squatting, frequent crossing of the legs, leg bone fractures, knee joint dislocations, excessive stretching of the knee due to trauma, nerve damage during surgical procedures, aneurysms (bubbles) formed in the peroneal vessels, bone tumors such as osteochondroma and joint cysts, tight elastic cover It results from applications such as wraps, bandages, plaster jackets, fiberglass splints, knee stabilizers, leg orthoses, tourniquets and ice packs.

In newly developing acute events, more motor involvement than sensory is in the foreground. In more chronic events such as cysts and tumors, there is pain and slowly progressive motor and sensory disturbances. Electrodiagnostic (EMG) evaluation is necessary for diagnosis and determination of the course of the disease. entrapment; Loss of consciousness can be seen occupationally in kneeling and bending as well as positional in patients under coma or general anesthesia. The reason for entrapment following excessive weight loss is the sensitivity of the nerve to trauma at the head of the fibula.

In mild cases, medication and exercise therapy are local, while physical therapy may be required in some patients. Surgery is required in cases that develop suddenly and do not improve with physical therapy. The operation is in the form of opening the sheath on the nerve with local anesthesia. Since the nerve will be freed from the pinched place, firstly the loss of strength and then the sensory loss will be corrected. It has been observed that the nerves do not recover even if they are operated on in patients who are under pressure for a long time.
