Peroneal nerve entrapment can develop with trauma or injury to the knee or fracture of the fibula bone. Other potential causes are tight casts or boots, pressure to the outer leg during sleep or surgery, and systemic conditions such as diabetes, Charcot-Marie-Tooth, and other autoimmune neuropathies. Diagnosing peroneal nerve entrapment will begin with a physical exam and imaging tests such as an MRI or ultrasound. Most patients will require a nerve conduction study and EMG to confirm the diagnosis.
To relieve pressure on the peroneal nerve, such options may include:. The only spinal infarction case, which reported vital signs  , reported stable values. Available literature describe temporal onset of subdural injections as 5—30 minutes and intrathecal injections as 1—2 minutes, respectively . Subdural and intrathecal blockades reported in this review [27,55] resolved within 8 hours. Supportive management of intrathecal and subdural injections was observed in this case review.
Traumatic spinal injury is also known to present with hypotension and bradycardia . Vital signs should be reported in future case reports to increase knowledge about how the clinical presentation of spinal cord infarction differs from reversible processes like subdural injection.
If the physician does not suspect intrathecal injection, a critical temporal window of opportunity—8 hours after onset of deficits—exists to decompress MOL to restore optimal neurological function. A delay in evacuation over 8 to 36 hours of epidural hematoma as well as the existence of preoperative deficits, a clot covering longer segments of the spine, and rapid progression of deficits portend worse outcome .
Management of the stabilized patient includes urgent access to neuroimaging to rule in or out infarction that is not reversible, in this review, vs MOLs, which are reversible after surgery in this review. Litigation alleging failure to respond or obtain necessary surgical intervention in a timely fashion is reported . Patients in this set of cases who underwent decompression had excellent recovery except one patient with subdural hematoma, who died of infectious complications .
If neuroimaging reveals infarction, supportive measures and possibly rehabilitation are indicated, but to reiterate, persons with MOLs require emergent decompression and access to a spine surgery center. At least two case reports described the need to transfer patients to higher levels of care. An important observation from this review is the potential need for immediate intubation and resuscitation in patients with deficits of quadriparesis and LOC.
The potential for morbidity and mortality in these groups was noteworthy. Subjects with paraparesis or single-limb deficits manifested no reported medical instability or death. Analytic methods that could stratify risk factors for mortality and morbidity of the LOC and quadriparesis groups vs the paraplegic and single-limb deficit groups should be considered in subsequent studies with larger numbers of subjects.
Reviewing case reports to study rare clinical events is not novel [16—18]. This review studied a presenting clinical complaint and then followed the convergence and divergence of the clinical course. Data reporting in the cases is not uniform. Data reported is nonparametric, categorical or nominal, and ordinal for temporal sequences.
The samples are small. The strategy to collect case reports is subject to self-selection biases. The strategy of combining infarctions over regions of the central nervous system, as well as comparing a diagnostic group with a combination of the other diagnostic groups to look at relative distributions of diagnoses in the permanent and reversible deficits are points of discussion. Statistical applications should be repeated in the future after more cases are reported to confirm the significant and trended observations in this review.
Nomenclature was problematic in two areas: alternative terminology for TF ESIs and spinal cord injury impairment levels. A strict criterion of nomenclature [60—62] is impractical because radiographic contrast is not used nor procedurally required in all cases. The variable nomenclature clouds the inclusion of cases, especially if details of the procedure are not reported. The absence of rectal tone has negative prognostic significance.
Incomplete lesions presence of some rectal tone or sensation have greater possibility for neurological recovery. The exam thought to have the most prognostic significance is that around 72 hours . In traumatic spinal-cord-injured subjects, incomplete lesions have a much greater chance of improvement of neurological level of injury and motor index scores . Younger patients and patients with Brown—Sequard syndrome, like two subjects in the reversible group [21,47] , have been shown to have better neurological outcome after spinal injury regardless of mechanism of injury .
Poor prognostic indicators for ambulation include delayed return over 48 hours of plantar responses . No conclusions about the predictive value of physical exam findings can be rendered from many of the referenced cases because of lack of data regarding rectal tone findings. Even though this review draws no conclusions about the use of high-dose intravenous methylprednisolone in the sample of persons with spinal cord injury after ESI, physicians may benefit from a review of the parameters of its use in persons with blunt trauma causing spinal cord injury and from criticisms of the treatment.
The comparison was with placebo, and the drug had to be started within 8 hours of injury . Motor scores improved 16 points with methylprednisolone given before 8 hours vs 11 points with placebo. Functionally, the improved motor score of 16 corresponds to gaining three myotomes of function from the original neurological level of injury, while the gain of 11 motor points in the placebo group corresponds to a gain of only two myotomes.
The studies have been rigorously criticized  for statistical analysis, randomization, clinical endpoints, and overall outcome, which Ghaly succinctly summarizes . The administration of methylprednisolone has also been associated with wound and lung infection, sepsis, gastric bleeding, and thrombosis [47,69]. Critics suggest that the use of methylprednisolone should be considered investigational only and that its administration may be harmful .
Methylprednisolone is contraindicated in penetrating trauma because of increased infectious and noninfectious complications and failure to change outcome [71,72]. The goal of applying neuroprotection strategies like methylprednisolone is the prevention of secondary mechanisms of injury related to reactive lipid peroxidation . Again, small numbers and incomplete data reporting preclude evaluating methylprednisolone as a treatment strategy after spinal cord injury related to ESI.
Current standard of care following spinal cord injury is support of arterial oxygenation and spinal cord perfusion pressure . Among the neurological deficits excluded from evaluation are visual deficits after ESI and spinal infections after ESI. Two etiologies of loss of visual acuity after ESI have been reported: central serous chorioretinopathy  CSC attributed to the exogenous administration of steroids by any route including ESI, and retinal hemorrhages [33—35] attributed to increased intracranial pressure translated to the retinal veins and resulting in hemorrhages.
Evaluation involves fundoscopic exam and fluorescein angiography in the CSC cases. CSC resolves if steroid exposure ceases. Retinal hemorrhages resolve spontaneously but are carefully monitored in the available cases. Only one case reports a slight but permanent decrease in visual acuity .
Also excluded are spinal infections. Spinal infections present with back pain and systemic signs antecedent to neurological deficits in most cases. The four stages of epidural abscess are backache, root pain, lower limb paralysis with bowel and bladder dysfunction, and paraplegia . Median time to onset of an infectious complication after ESI is 7 days  , with reports as early as 72 hours .
Diagnostic screening is possible with sedimentation rates and C-reactive proteins; however, only MRI is definitive . Early treatment before the development of neurological signs promotes the best outcomes so a high index of clinical suspicion is key .
Treatment involves antibiotics and urgent decompressive laminectomy . This review collected the available case reports on neurological deficits presenting after ESI. However, adverse outcomes after ESI and interventions for pain are unreported for reasons ranging from inattention to litigation [3,44]. In this review, only three cases of reversible neurological deficits are reported after [21,26,46] while thirteen permanent deficits are reported [3,23,24,25,44,49—53].
It is unclear why there is this discrepancy. Any number of hypotheses can be proposed. A different database, the American Society of Anesthesia's Close Claims Project  , reports incidences and mechanisms of injury related to ESI of similar magnitude and type. Fourteen events of nerve injury after ESI with six resulting in paraplegia and one quadriplegia are reported. Infections in the neuroaxis subsequent to ESI were litigated, including 12 cases of meningitis and seven cases of epidural abscess.
Death or brain damage resulted from ESI in nine cases. A third source of information, retrospective reviews, mentions epidural hematoma and radicular injury but not the associated neurological deficits or treatment and outcomes. Regardless, Closed Claims suggests litigation occurs for both permanent and temporary injuries .
This review of 33 cases suggests that interventional pain physicians have responded well empirically to sudden neurological deficits after ESI. Respiratory complications may have to be managed in episodes of LOC and quadriparesis. When neurological deficits progress or alter from a pattern of resolution consistent with intrathecal or subdural injection, prompt progression to neuroimaging for hematoma is imperative in order to get patients to decompressive surgery within 8 hours.
Infarctions, which result in permanent neurological deficits and have no specific treatment other than supportive measures, appear to be increasing in incidence in more recent literature.

The probe is observed to pass easily through the path of the exiting nerve root, across the midline of the canal, and down the path of the traversing nerve root, past the pedicle. Figures 7A and 7B. Kim's laser endoscopic spine surgery website explains the procedure in more detail. Figures 8A and 8B. Kim details the case of a patient with an L5 radiculopathy who presents primarily with weakness as opposed to pain. She failed a course of nonoperative therapy.
Previously, she had a L4-L5 microdiscectomy. Her imaging studies demonstrate a tremendous loss in lumbar lordosis, as well as a coronal plane deformity. There is no instability on the dynamic films. The patient was successfully treated with an endoscopic discectomy on the right at L4-L5. She made an excellent recovery in terms of motor function, but the date of follow-up is not provided. This is an excellent case to consider. Although her imaging studies clearly show her spinal alignment is suboptimal, she does not have back pain and only presents with a radiculopathy.
Therefore, Dr. Kim's choice to treat only the radiculopathy is most appropriate. It would be completely unreasonable to perform a major realignment and reconstruction at this point in time. Unfortunately, for this woman, at some point in her life, she will probably require more extensive surgery. However, as time passes, the techniques will improve and as that occurs, one would expect the risk of complication to decrease.
Therefore, to allow her to be fully active at this time without a large fusion is the best choice. Many surgeons do not use the endoscope and prefer to do these procedures using a minimally invasive approach with the microscope. This allows for true 3-D visualization and decreases the need for extra equipment in the operating room.

Foot drop due to compression of spinal nerve roots when a vertebra slips over the adjacent vertebra below it may be treated with:. Spinal fusion surgery may be required in severe spondylolisthesis. Foot drop due to fracture of the vertebrae and nerve damage may be treated with medication and a lumbar brace.
Sometimes, minimally invasive procedures such as vertebroplasty or kyphoplasty may be performed, where bone cement is injected to stabilize and reform the fractured vertebra. Watch Spinal Compression Fracture Video. Treatment typically depends on the type of trauma to the peroneal nerve. A few examples include 1 :.
Surgery may be recommended in the treatment of laceration injuries, acute compartment syndrome, and tumors. Surgery may include nerve repair, nerve grafting, or tendon grafts. The electric stimulators help treat foot drop by applying small electrical currents to the peripheral nerves through electrodes that are controlled wirelessly by in-shoe sensors.
Foot drop may cause mild to severe disability and may be associated with pain and other symptoms. The long-term outlook is generally favorable and depends on the severity and type of the cause.
