The physical exam was remarkable for pain and swelling over the head of the fibula and her history was negative for trauma. MRI revealed a mass overlying the right fibular head with CPN compression. [peripheralnerve.org]
These patients have "centralized pain" which means their pain doesn’t respond to the procedures on the nerve itself and instead these patients require the expertise of pain management specialist. [northjerseypodiatry.com]
- Inflammation
On exam, there are no signs of inflammation or deformities on her foot. [medbullets.com]
The swelling can lead to inflammation and scarring, and the scarring can interfere with the function of the nerve itself. Often, if the pressure on the nerve is released, this cascade effect can be broken. [nerve.wustl.edu]
Swelling, inflammation or infection can also injure the peroneal nerve as can repeated pressure on the outside of the knee from for example sitting with legs crossed in tight clothing. [sportsinjuryclinic.net]
I still can't see physiologically, how tiny needles, placed distant to a site of inflammation, can make that inflammation go away. I can see how it would gate the pain, but not for long if the inflammation persists. [podiatryarena.com]
To help reduce any swelling or inflammation of the nerve, your doctor may administer corticosteroid shots. [chronicbodypain.net]

The etiology of ulnar nerve entrapment includes trauma, arthritis, and systemic diseases (less often than in CTS). As in CTS, conduction through the elbow is decreased. [care.diabetesjournals.org]
- Muscle Weakness
Muscle weakness is usually noticed later, and is often associated with muscle atrophy. A compression neuropathy can usually be diagnosed confidently on the basis of the symptoms and signs alone. [en.wikipedia.org]
However, pain inhibition can cause temporary muscle weakness in certain leg positions. [neckandback.com]
Symptoms General symptoms of nerve compression include pain, numbness, tingling and muscle weakness to the affected area. Since this term can apply to any nerve or nerve bundle, specific symptoms will vary. [livestrong.com]
However, although addressing the scar tissue frees the nerve and makes the muscles healthier, the muscles of the knee or leg may still be somewhat tight or weak. [kinetesisspineandjoint.ca]
The most common symptoms include: Localized or referred pain (check local peripheral nerve territories); Numbness, tingling, or "eletric shock" feeling; Paresthesia; Burning sensation; Impaired movement of affected body part; Muscle weakness; Muscle wasting [physio-pedia.com]

Rheumatoid Arthritis Peripheral neuropathy associated with rheumatoid arthritis was described by Lisak in 2014. Peripheral neuropathy occurs in 10% of patients with rheumatoid arthritis. [spineuniverse.com]
Peroneal Nerve Dysfunction Peroneal nerve dysfunction is a type of peripheral neuropathy that is specific to the peroneal nerve. The peroneal nerve is branch of the sciatic nerve, which supplies movement and sensation to the lower extremities. [acsneuro.com]
Similar to carpal tunnel syndrome surgery, nerve decompression surgery helps improve symptoms of diabetic peripheral neuropathy of the foot and prevents amputation. [practicalpainmanagement.com]
Peroneal nerve dysfunction is a type of peripheral neuropathy (damage to nerves outside the brain or spinal cord). This condition can affect people of any age. [bnchiro.com]
For example, those with diabetes may suffer from peripheral neuropathy, a form of nerve entrapment, which affects the tips of nerve endings near the skin surface. Symptoms will be sensitivity to touch, foot ulcerations and difficulty walking. [livestrong.com]

- Sciatica
Some of the most well-known forms of nerve entrapment include diabetic neuropathy, carpal tunnel syndrome and sciatica. Causes of nerve entrapment will vary, but weight loss may be a factor for some people. [livestrong.com]
I was reaching the stage where I would have tried almost anything within reason to alleviate the sciatica. For me, the proof of the pudding was in the eating. My life had been on hold for 8 months. [podiatryarena.com]
In patients with motor or sensory disturbance, other neurological disorders should be excluded, with sciatica and more specifically L5 radiculopathy being the most common. [neupsykey.com]
Workup
While we do recommend the use of an EMG/NCV as part of the workup to validate that the nerve irritation is coming from entrapment at the fibular head/neck region, it is actually very rare that these findings are positive on these studies. [drrobertlaprademd.com]
In addition, consideration should be given to a metabolic workup to rule out thyroid dysfunction and diabetes in select individuals. Further workup may be necessary to rule out lumbar radiculopathy. [bizwan.com]
Treatment
Based on which of the three aforementioned compression sites or their combination is identified; surgical treatment is aimed towards your symptomatic sites (anatomical cause of the neuropathy). [drducicplasticsurgery.com]
Treatment [ edit ] When an underlying medical condition is causing the neuropathy, treatment should first be directed at this condition. [en.wikipedia.org]
Dynamic ultrasonography or magnetic resonance imaging is often used to confirm diagnosis and guide treatment. Most symptomatic cases respond successfully to conservative treatment, with surgery reserved for refractory cases. [ncbi.nlm.nih.gov]
Treatment options Treatment options include anti-inflammatory medications or injections to relieve any swelling at the source of the problem. We may also recommend bracing to relieve pressure. Many cases respond to these conservative measures. [afaig.com]
Treatment – Resolving Peroneal Nerve Entrapment The proper treatment of peroneal nerve entrapment must not only address problems with the peroneal neve, but MUST also correct any biomechanical problems at the hip or foot as well (remember, these factors [kinetesisspineandjoint.ca]
Prognosis
Abnormal activity after 10–14 days Abnormal activity (fibrillation potentials and positive sharp waves) Prognosis Recovery within months Poor prognosis if the endoneurium is breached and surgery may be required. [academic.oup.com]
The prognosis for patients with peroneal nerve dysfunction depends on the underlying cause. This condition is not normally life-threatening, but the pain can be uncomfortable. [acsneuro.com]
EMG testing also helps to determine the prognosis of the injury. Treatment Treatment is often based on the type of problem that caused the nerve injury. [vermontspineworks.com]
[…] objectively document the conduction block; - if possible should be performed w/ in one month of injury; - amplitude of the sensory potential and decreases in nerve conduction velocities are used to confirm sensory and motor deficits, respectively; - prognosis [wheelessonline.com]
Outlook (Prognosis) The outcome depends on the cause of the problem. Successfully treating the cause may relieve the dysfunction, although it may take several months for the nerve to grow back. [neuropaxclinic.com]
Etiology
Other etiologies include anomalies of the EHB distal to the retinaculum. [bizwan.com]
Other etiologies include anomalies of the extensor hallucis brevis distal to the retinaculum. [emedicine.medscape.com]
While the true incidence is not known, the etiology has been classified as secondary to a congenital (or constitutional) fascial weakness, or acquired fascial defect, usually secondary to direct or indirect trauma. [ncbi.nlm.nih.gov]

Pathophysiology of nerve compression. Hand Clin. 18(2): 231-41. ↑ Tapadia, M., Mozaffar, T., & Gupta, R. (2010). Compression neuropathies of the upper extremity: update on pathophysiology, classification, and elecrodiagnostic findings. [physio-pedia.com]
The pathophysiological features are described in Table 1. [academic.oup.com]
Pathophysiology [ edit ] External pressure reduces flow in the vessels supplying the nerve with blood (the vasa nervorum ). This causes local ischaemia, which has an immediate effect on the ability of the nerve axons to transmit action potentials. [en.wikipedia.org]
A history of severe inversion ankle sprain or blunt trauma to the ankle, leg, or fibular head can be helpful in identifying likely pathophysiologic mechanisms. [clinicalgate.com]
Many theories exist about the pathophysiology of this compression, including ischemia, inflammation, soft-tissue trauma, tumor, muscle imbalance, and fibrous ingrowth. [emedicine.medscape.com]
Prevention
Similar to carpal tunnel syndrome surgery, nerve decompression surgery helps improve symptoms of diabetic peripheral neuropathy of the foot and prevents amputation. [practicalpainmanagement.com]
Prevention Avoid putting long-term pressure on the back or side of the knee. Treat injuries to the leg or knee right away. [neuropaxclinic.com]
Conclusion: Ganglionic impingement neuropathy presents more challenges to the physician and may require multiple imaging and operative interventions to diagnose and prevent permanent impairment4. [peripheralnerve.org]
Orthopedic devices may improve your ability to walk and prevent contractures. These may include braces, splints, orthopedic shoes, or other equipment. [medlineplus.gov]
This is not true muscle weakness but an actual subconscious reflex to prevent pain from occurring by subconsciously refusing to contract the muscle for fear of pain. [neckandback.com]
