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
