Entrapment neuropathy is especially caused by the compression of the nerve passing through the anatomical taps. Lower limb entrapment neuropathies are seen less common than upper limb. Anamnesis is very important in making a diagnosis. The patient`s weight changes and life habits should be questioned firstly. The rapid weight gain may cause compression of the nerve on the other hand the rapid weight decrease may cause the nerve to be entrapment by subjecting it to pressure directly. The patient`s profession is also very important. Nerves may also be exposed to pressure in athletes exercising heavily the same as in person working that require permanent sitting. On the other hand, systemic diseases (diabetes mellitus, hipotridi …) can cause a buildup of metabolites, causing pressure on the nerve. The drugs used by the patient constantly should be questioned. While anticoagulant drugs can cause compression syndrome, and may create compression with local hematomas in continuous intramuscular injections. The surgeries that the patients have undergone are also very important. In operations close to the nerve trace, scar tissue can compress the nerve, and in long-term operations may cause the nerve to be trapped as positionally. Because of this, anamnesis taken carefully is very important for making correct diagnosis.
