Deep Peroneal Nerve

First a brief about Common Peroneal Nerve

Two sensory branches

 1. Lateral Sural Cutaneous Nerve

      skin over lateral aspect of knee and proximal third calf

2. Branch that joins tibial anastomotic branch to form surnal nerve

     skin over posterolateral aspect of calf and over lateral malleolus , lateral aspect of foot , over 4th

     and 5th toes

Motor Supply

 1. Superficial Peroneal Nerve

    Motor ;     Peroneus Longus and Brevis

    Sensory;   Anterior and Lateral aspect of leg and dorsum of foot

2. Deep Peroneal Nerve

    Motor; Anterior Tibialis , Extensor Digitorum longus , EHL , Peroneus Tertius , Ist dorsal   


     interosseus

 (   Sensory; Ist web space via digital cutaneous nerve (lateral aspect of dorsum of great toe and

     medial  aspect of 2nd toe )


Treatment

   1.Splint

  2. ROM Exercises

 3. Repair - 60 - 70 % patients recover motor function .

      (nerve repair techniques  already discussed in previous section . )

4. Tendon Transfer

        Split Tibialis Posterior tendon
