Ilioinguinal nerve
  • Can be caused by hypertrophied abdominal muscles as a result of intensive training
  • Hyperesthesia is common
  • Pain worse with hyperextension of hip
  • Treatment
    • operative
      • surgical release
        • indications
          •  failure of nonoperative management
Obturator nerve
  • Found in patients with well-developed hip adductors (skaters)
  • Can cause chronic medial thigh pain
  • Nerve conductions studies help establish diagnosis
  • Treatment
    • nonoperative
      • supportive
Lateral femoral cutaneous nerve
  • Can lead to pain on lateral aspect of proximal leg
    • meralgia paresthetica
  • Exacerbated by tight belts and prolonged hip flexion
  • Treatment
    • nonoperative
      • PT, NSAIDS
        • postural exercises
        • release of compressive devices
Sciatic nerve
  • Can occur anywhere along the course of the nerve
  • Most common locations
    • at level of ischial tuberosity
    • at the piriformis muscle (piriformis syndrome
Saphenous neuritis
  • Compression of the saphenous nerve, usually at Hunter's canal
    • also known as surfer's neuropathy
  • Caused by kneeling for long periods of time
  • Symptoms
    • pain inferior and medial to knee
  • Treatment
    • nonoperative
      • knee pads
        • indications
          • first line of treatment
Common peroneal nerve
  • Can be compressed behind fibula by a ganglion cyst or injured by a direct blow 
  • Fusion of the proximal tibiofibular joint may be needed to prevent cyst recurrence
Superficial peroneal nerve
  • Due to a fascial defect
    • usually ~ 12 cm proximal to lateral malleolus where it exits the fascia of the anterolateral leg 
  • Mechanisms include
    • inversion injury
    • fascial defect
  • Presentation
    • numbness and tingling over dorsum of foot
    • worsens with plantar flexion and inversion of foot
  • Treatment
    • nonoperative
      • observation
        • indications
          • usually preferred treatment
    • operative
      • fascial release
        • indications
          • may be indicated in refractory cases or for elite athletes
Deep peroneal nerve
  • Can be caused by inferior extensor retinaculum
  • Also known as anterior tarsal syndrome 
Posterior tibial nerve
  • Also known as Tarsal Tunnel syndrome 
Lateral plantar nerve
  • Caused by compression of the first branch of the lateral plantar nerve, also known as Baxter nerve (branch to the abductor digiti quinti) 
    • common nerve entrapment in the running athlete  
    • becomes compressed between fascia of abductor hallucis longus and medial side of quadratus plantae  
  • Treatment
    • operative
      • surgical release of abductor hallucis fascia
Medial plantar nerve
  • Compression of medial plantar nerve at point where FDL and FHL cross (Knot of Henry)
    • also known as Jogger's foot
  • Most common cause of compression is foot orthotics
  • Treatment
    • nonoperative
      • discontinue foot orthosis
Sural nerve
  • Can occur anywhere along the course of the nerve
  • Most vulnerable 12-15mm distal to the tip of the fibula as the foot rests in equinus position
  • Treatment
    • operative
      • surgical release
Interdigital neuroma
  • Also known as Morton's neuroma
