Presentation
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]
The clinical presentation and severity of peroneal nerve neuropathy, due to excessive pressure on or injury to the nerve varies based on which of its three branches and compression sites are actually present: Common peroneal nerve neuropathy is the most [drducicplasticsurgery.com]
We present the case of a 67-year-old man with pain down the lateral aspect of the left lower limb of 18 months duration. [casereports.bmj.com]
We present a rare and unusual case of a patient undergoing spinal surgery at the level of L5/S1 and presenting 4 weeks postoperatively with progressive foot drop. [omcr.oxfordjournals.org]
Needle examination may reveal the presence of fibrillations and positive sharp waves in the EDB only if present at the anterior tarsal tunnel. If entrapment is present more proximally, the denervation is present in the TA as well as in the EDB. [bizwan.com]

Foot Drop
Although compression of the peroneal nerve by an intramuscular ganglion cyst is rare, this entity should be considered in the differential diagnosis for the cause of foot drop. Figure 1A & 1B. [peripheralnerve.org]
Patients with peroneal nerve compression neuropathy may experience numbness over the dorsum of the foot, toe extension weakness or foot drop, in addition to pain. [drducicplasticsurgery.com]
Abstract Foot drop is a debilitating condition, which may take many months to recover. The most common cause of foot drop is a neuropathy of the common peroneal nerve (CPN). [omcr.oxfordjournals.org]

Peripheral Neuropathy
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]
Diagnosis of PPNI A thorough history and clinical examination are essential to localize the lesion and to identify a pre-existing peripheral neuropathy. [academic.oup.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]
She was diagnosed as having recurrence of lateral meniscus tear and was suggested operative treatment. She visited our clinic in April 1999. [jstage.jst.go.jp]
Anatomical considerations need to be taken into account and operative treatment has been recommended due to the favourable outcome in this case. [casereports.bmj.com]

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]
Prognosis

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]
In general the prognosis for recovery is good (Stuart et al ., 1989; Berry and Richardson, 1976; Mumenthaler and Schliack, 1991). However, it was difficult to convince the patient of this. [oandplibrary.org]
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
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 Avoid putting long-term pressure on the back or side of the knee. Treat injuries to the leg or knee right away. [neuropaxclinic.com]
Prevention of PPNI The ASA has produced a practice advisory notice for the prevention of PPNIs. 8 A sound knowledge of anatomy and the risks posed by positioning patients for surgery is essential in understanding the preventive strategies. [academic.oup.com]
