Peroneal Nerve Compression Neuropathy

Neuropathy Entrapment Peroneal Nerve


Presentation

  • 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]
  • 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]
  • Snapshot A 30-year-old woman presents to her primary care physician for left foot pain. The patient reports experiencing a dull ache in the plantar aspect of the left foot.[medbullets.com]
  • In this paper, we present a case of peroneal neuropathy that was originally misdiagnosed as a lumbar radiculopathy.[chiromt.biomedcentral.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]
Swelling
  • Diabetic patients, due to abnormal glucose metabolism, may develop swelling of the nerve, as well as narrowing of the tunnel itself.[drducicplasticsurgery.com]
  • Causes The condition is related to injury or can result from other problems such as ankle sprain, flat feet, nerve compression stemming from complication of diabetes, and varicose veins or swelling that may cause the nerve to become compressed.[afaig.com]
  • This accumulation, in turn, causes swelling and pressure within the nerve. The swelling can lead to inflammation and scarring, and the scarring can interfere with the function of the nerve itself.[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]
  • Possible causes of tarsal tunnel syndrome include diabetes, arthritis, flat feet, fallen arches, enlarged tendons, or swelling from an ankle sprain.[health.ucsd.edu]
Surgical Procedure
  • For more severe peroneal nerve injuries, your doctor may recommend a surgical procedure to decompress the nerve, repair the nerve with grafts or sutures, or transfer other nerves or tendons to support function of your leg and foot.[hopkinsmedicine.org]
  • Arch Neurol 1989; 46: 1355–60Dawson, DM Krarup, C Massey EW, Pleet AB: Compression injury of the sciatic nerve during a prolonged surgical procedure in a diabetic patient.[anesthesiology.pubs.asahq.org]
  • Most surgeons in the United States perform a primary surgical procedure via a dorsal approach.[emedicine.medscape.com]
  • Common etiologies for proximal entrapment of the deep peroneal nerve include space-occupying lesions about the proximal fibula, surgical procedures about the lateral knee (including proximal tibial osteotomy), and chronic anterior exertional compartment[bizwan.com]
  • This article will review the science behind DPN and explain how this surgical procedure may benefit your diabetic patients.[practicalpainmanagement.com]
Severe Pain
  • During examination, the patient was able to tolerate light touch related to compression-type injury rather than withdrawing from severe pain in keeping with a neurectomy-type injury; thus compression neuropathy and not neuroma injury was suspected.[passioeducation.com]
Vascular Disease
  • Physical examination excluded diabetes, alcoholism, vascular disease and a root syndrome of L5. The sustained compression by the lateral rim of the prosthesis was suspected to be the cause of this complaint.[oandplibrary.org]
  • disease of the lower extremities; their smoking history; and any family history of peripheral nerve problems.[anesthesiology.pubs.asahq.org]
Hypotension
  • Intraoperative hypotension, hypothermia, and dehydration should be avoided.[academic.oup.com]
Knee Pain
  • A 24-year-old female had accepted arthroscopic meniscectomy for left lateral knee pain. Postoperative course was uneventful. Two years after the operation, she noticed left lateral knee pain and spastic feeling on the lateral aspect of her left leg.[jstage.jst.go.jp]

Contusion
  • Because of its superficial location and anatomical course, focal peroneal nerve dysfunction may result from a direct contusive injury to the nerve at the fibula head, or in association with knee injury or knee surgery.[neupsykey.com]
  • Trauma Wounds Contusions Proximal fibular fractures knee dislocations Tibial osteotomies Total knee Arthroscopy Limb lengthening procedure Tumors Tumors could be intraneural or extraneural.[boneandspine.com]
  • Contusion of the common peroneal nerve caused by blunt trauma can have functional recovery within days or weeks with minimal treatment.[healio.com]
  • However, in a study of 146 cases, Piton et al noted 55 cases due to idiopathic causes, 16 due to external compression, 59 due to various traumatic causes, and nine due to intraneural and extraneural tumors. [30] Traumatic causes can include wounds and contusions[emedicine.medscape.com]
Muscular Atrophy
  • Neuropathy peroneal nerve requires differential diagnosis of radiculopathy level LV-SI, recurrent hereditary neuropathy, a disease of Charcot-Marie-Tooth syndrome ACA (peroneal muscular atrophy), BAS, polyneuropathy, mononeuropathy other lower limbs,[medicalformat.com]
  • Inspection should focus on limb asymmetry, muscular atrophy, or abnormal posture (both spinal and peripheral).[physio-pedia.com]

  • Peroneal neuropathy (foot drop) Occurs when the peroneal nerve (located in the leg below the knee) is injured or damaged.[health.ucsd.edu]
Peripheral Neuropathy
  • 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]
  • The “first crush” would be the peripheral neuropathy of diabetes and the “second crush” compression of the tibial nerve at the tarsal tunnel.[care.diabetesjournals.org]
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

  • 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]

  • 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]
  • 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]
  • 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]
