The peroneal paresis

Peroneus paresis is a partial or complete failure of the foot lifter muscles. The underlying cause of muscle paralysis is a nerve injury. Affected is the N. peroneus communis, which is a branch of the N. ischiadicus (sciatic nerve).

The ischiadicus nerve originates in the lumbar spine. Possible causes of a nerve injury are a narrowing of the origin of the sciatic nerve in the lumbar spine due to a herniated disc, a lesion in the central nervous system as in a stroke or cerebral hemorrhage, and trauma in the area of the nerve path, e.g. at the level of the knee. Furthermore, surgical measures in the groin and hip region, lymph node removal or a plaster cast that is too tight in the case of a fracture of the lower extremities can lead to peroneal paresis. The nerve is restricted in its function due to the injury or entrapment, resulting in typical symptoms.

Summary

Peroneal paresis is the loss of the nerve that innervates the foot lifter muscles. Patients affected by peroneal paresis pull the foot while walking and usually feel a loss of sensation in the affected area. Through appropriate physiotherapeutic exercises, mobility in the entire body can be improved and muscle activity can be increased through targeted stimulation of the peroneal nerve.Patients are usually fitted with a foot lifter splint to support them when walking, which reduces the risk of tripping. How long the healing process for peroneal paresis takes depends on the cause and extent of the muscle weakness.
