Peripheral Entrapment Sites

The common fibular nerve (common peroneal nerve; external popliteal nerve; lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the posterolateral part of the leg and the knee joint. Deep peroneal nerve is the nerve of the anterior compartment of the leg and the dorsum of the foot. It is one of the terminal branches of the common peroneal nerve. It corresponds to the posterior interosseus nerve of the forearm.

1. Decreased sensation, numbness, or tingling in the top of the foot or the outer part of the upper or lower leg. 2. Foot that drops (unable to hold the foot up) 3. "Slapping" gait (walking pattern in which each step makes a slapping noise) 4. Toes drag while walking. 5. Walking problems. 6. Weakness of the ankles or feet.

The most common cause is a disc prolapse at the L2/3 or L3/4 vertebra in the spine. ... The femoral nerve is also commonly pinched in cases of hip arthritis, with patients often reporting pain travelling down the front of the thigh to the knee.

An entrapment of the femoral nerve by an iliopsoas hema- toma is the most likely cause of femoral nerve palsy. Direct blows to the abdomen or a hyperextension moment at the hip that tears the iliacus muscle may produce an iliacus hematoma.PIP, SID, TED

Dorsal Scapular Nerve Entrapment. The dorsal scapular nerve is a relatively unknown nerve entrapment that causes shoulder and arm pain. Because the nervepasses through the middle scalene muscle, it can be traumatized during brachial plexus injections. It can be a cause of thoracic outlet syndrome.

Long Thoracic Nerve

A thickening of the tissue around a nerve leading to the toes. Morton's neuroma may be caused by pressure or injury, such as from running or use of high heels. Morton's neuroma may feel like a pebble in a shoe or a fold in a sock. There may be sharp, burning pain or numbness in the ball of the foot or toes. Treatment might include arch supports and foot pads, corticosteroid injections, strength exercises, wide-toe shoes, or surgery.

Morton's Neuroma

Fibular (peroneal) neuropathy is the most common mononeuropathy encountered in the lower limbs. Clinically,sciaticmononeuropathies,radiculopathiesofthe5thlumbarroot,andlumbosa- cral plexopathies may present with similar findings of ankle dorsiflexor weakness, thus evaluation is needed to distinguish these disorders. The most common site of injury to the fibular nerve is at the fibular head. The deep fibular branch is more frequently abnormal than the superficial branch.

The nerve may be compressed within the true pelvis from pelvic fractures, by pelvic hematomas secondary to trauma, and by intrapelvic tumors. ... The entrance to the obturator foramen has been proposed as the site of obturator nerve entrapmentwhere both divisions were damaged.

Obturator

The common fibular nerve (common peroneal nerve; external popliteal nerve; lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the posterolateral part of the leg and the knee joint. It divides at the knee into two terminal branches: the superficial fibular nerve and deep fibular nerve, which innervate the muscles of the lateral and anterior compartments of the leg respectively. When the common fibular nerve is damaged or compressed, foot drop can ensue.

Peroneal neuropathy is the most common entrapment neuropathy in the lower extremity and accounts for 15% of all mononeuropathies in adults [1]. Peroneal nerve injury can result in numbness, tingling or weakness manifesting as a foot drop.

Suprascapular nerve entrapment is caused by compression of the suprascapular nerve as it passes through the suprascapular notch. m, Muscle. This entrapment neuropathy manifests most commonly as a severe, deep, aching pain that radiates from the top of the scapula to the ipsilateral shoulder.

Suprascapular Neuropathy

The sural nerve (see Fig. 3-20) is a sensory branch of the tibial nerve. It is formed by the lateral sural cutaneous nerve from the common fibular (peroneal) nerve and the medial calcaneal nerve from the tibial nerve. The sural nerve supplies the skin on the posterior-lateral aspect of the lower one-third of the leg and the lateral side of the foot.

Sural Nerve

Name the Tibial nerve entrapment sites It can be entrapped at two major sites: behind the knee at the proximal edge of the soleus muscle and at the ankle in the tarsal tunnel. The small terminal branches of the tibial nerve can be entrapped in the distal ankle and foot and are discussed in other chapters.
