Damage to the sciatic nerve

The sciatic nerve can become trapped in the ischial tuberosity by a hernia (similar to a hernia) and cause pain. Paralysis and pain can also be caused by fractures or dislocations, e.g. as a result of trauma. Intramuscular injections, e.g. into the buttocks, can also lead to nerve damage, especially if they are not carried out properly.

Inflammation can also be the cause of damage. Not infrequently, the sciatic nerve is also affected by a herniated disc. The pain is also called sciatica. Lumbago is understood to be back pain without radiation into the leg. If the pain occurs in combination, this is called lumboischialgia.

Damage to the fibula nerve

Disturbances of the common fibula nerve can be recognized by gait disorders and foot malpositions. If the nerve is damaged before it splits into its two end branches, the inward rotation (pronation) and the extension of the lower leg can be paralyzed or weakened. The result is a pointed foot-clumpy foot position (Pes equinovarus).

If an injury occurs beyond the branch, an isolated loss or disruption of the branch and the muscles it controls is impressive, depending on the end branch damaged. If the deep branch is affected (nervus fibularis profundus), this results in a disturbance of the extension, which is known as pointed foot or weakness of dorsiflexion (pes equinus). This results in a gait disorder (stepper gait), in which increased flexion in the hip and knee joint is necessary so that the tip of the foot does not drag on the ground when walking. On the other hand, damage to the superficial branch (superficial fibular nerve) appears as a disorder of inward rotation (pronation). In addition to the motor deficits, there may also be disturbances in sensation.

Damage to the tibial nerve

Damage to the tibial nerve or its end branches usually results in paralysis of the short foot muscles and/or in sensory disturbances up to pain. The so-called tarsal tunnel syndrome can occur due to an anatomical narrowing in the course of the nerve at the inner ankle through compression.
