The common peroneal nerve usually takes about 3 months to 1 year to recover depending on the severity of the injury. If the common peroneal nerve is completely severed, then the minimum recovery time is ~ years, with a minimum of 3 months of recuperation if the nerve is localized and stretched or compressed. The common peroneal nerve can innervate the muscles of the anterior and lateral groups of the lower leg, which can make the ankle dorsiflexion and valgus as well as dorsiflexion of the toes. If the common peroneal nerve is injured, it may manifest itself as inability of dorsiflexion of the foot, foot drop deformity with inversion, inability of the toes to dorsiflex, and a cross-threshold gait. Mild peroneal nerve dissection can be treated with oral medication, such as medication that promotes nerve inflammation to subside and nerve tissue recovery. Severe peroneal nerve dissection requires surgery to reanastomose the severed end. If the above situation occurs, it is recommended to go to a regular hospital to find a professional doctor for treatment.
