New York State Medical Treatment Guidelines for Pronator Syndrome (Median Neuropathies in the Forearm) in workers compensation patients

The guidelines crafted by the New York State workers compensation board are designed to aid physicians, podiatrists, and healthcare professionals in delivering suitable treatment for Pronator Syndrome, specifically addressing Median Neuropathies in the Forearm.

These guidelines from the Workers Compensation Board serve as a helpful resource for healthcare professionals, offering guidance on determining the most fitting level of care for patients dealing with Pronator Syndrome.

It’s important to note that these guidelines don’t replace the need for clinical judgment and professional expertise. The ultimate decision regarding patient care should be a collaborative process between the patient and their healthcare provider.

Pronator Syndrome (Median Neuropathies in the Forearm)

Median nerve entrapment occurring beneath or within the pronator teres muscle in the proximal forearm is the root cause of pronator syndrome. A key aspect in distinguishing it diagnostically is the onset of paresthesias and flexor forearm pain akin to those seen in carpal tunnel syndrome. Pronator syndrome is believed to result in nocturnal awakenings less frequently than carpal tunnel syndrome. An additional electrodiagnostic investigation is both beneficial and recommended for accurate diagnosis.

Diagnostic Testing for Pronator Syndrome – Electrodiagnostic Study is recommended to confirm the presence of Pronator Syndrome.

Medications for Pronator Syndrome (Median Neuropathies in the Forearm)

For the majority of patients, ibuprofen, naproxen, or other NSAIDs from an earlier generation are proposed as the initial treatments. In cases where NSAIDs are not suitable, acetaminophen (or its analog, paracetamol) may serve as a viable alternative, although research generally suggests it is slightly less effective than NSAIDs.

There is evidence indicating that NSAIDs, compared to opioids like tramadol, are both less risky and equally effective in pain management.

Non-Steroidal Anti-inflammatory Drugs (NSAIDs) for the Treatment of Acute, Subacute, Chronic, or Postoperative Pronator Syndrome Pain are recommended to manage postoperative, chronic, or subacute Pronator Syndrome pain.

Indications – NSAIDs are recommended as a treatment for acute, subacute, chronic, or postoperative Pronator Syndrome pain. Initial attempts with over-the-counter (OTC) medications should be made to gauge their efficacy.

Frequency/Dose/Duration – For many patients, using NSAIDs as needed may be deemed appropriate.

Indications for Discontinuation – Cessation of elbow discomfort, lack of medication efficacy, or the emergence of adverse side effects necessitating discontinuation.

For Patients at High Risk of Gastrointestinal Bleeding, NSAIDs are recommended. Cytoprotective drugs like misoprostol, sucralfate, histamine Type 2 receptor blockers, and proton pump inhibitors are commonly prescribed in combination for individuals at elevated risk of gastrointestinal bleeding.

Indications – Cytoprotective drugs should be considered for patients with a high-risk factor profile who also require NSAIDs, particularly if an extended course of treatment is planned. Those with a history of gastrointestinal bleeding, the elderly, diabetics, and smokers are particularly vulnerable.

Frequency/Dose/Duration – H2 blockers, misoprostol, sucralfate, and proton pump inhibitors are advised, following the manufacturer’s dosage recommendations. There are generally no significant variations in effectiveness observed in preventing gastrointestinal bleeding.

Indications for Discontinuation – Intolerance, the emergence of negative effects, or the cessation of NSAIDs.

NSAIDs for Patients at Risk of Cardiovascular Adverse Effects

For individuals at risk of cardiovascular side effects, the recommended initial treatments are acetaminophen or aspirin, deemed safer options. If necessary, non-selective NSAIDs are suggested over COX-2-specific medications.

To mitigate the risk of an NSAID counteracting the protective effects of low-dose aspirin in those using it for primary or secondary cardiovascular disease prevention, the NSAID should be taken at least 30 minutes after or eight hours before the daily aspirin.

Acetaminophen for Elbow Pain Treatment

Acetaminophen is advised for addressing elbow discomfort, particularly in cases where NSAIDs are contraindicated.

Indications – Applicable to all individuals, regardless of the severity, be it chronic or post-surgery elbow pain.

Frequency/Dose/Duration – In accordance with the manufacturer’s recommendations; can be utilized as needed. However, exceeding four gm/day shows evidence of liver toxicity.

Indications for Discontinuation – Upon resolution of discomfort, appearance of adverse effects, or intolerance.

Opioids

Opioids are not recommended for acute, subacute, or chronic pronator syndrome.

Opioids are suggested for a maximum of one week to manage postoperative pronator syndrome pain.

Rationale for Recommendations: There is a lack of robust trials evaluating the effectiveness of opioids in treating pronator syndrome.

Opioids carry significant side effects, including low tolerability, constipation, drowsiness, impaired judgment, memory loss, and the potential for overuse or dependency, observed in up to 35% of patients. Patients should be informed about these potential side effects and cautioned against operating machinery or driving before receiving an opioid prescription.

Opioids should only be employed when essential for severe pain or for a brief period (not exceeding one week) in the postoperative phase. This is because they do not appear to be more effective than safer analgesics in managing the majority of musculoskeletal complaints. Except for a short postoperative course, opioids are not recommended for pronator syndrome treatment.

 

Glucocorticosteroids – Oral or Injections

The use of glucocorticosteroids, whether orally or through injections, is discouraged for treating Pronator Syndrome, be it in the acute, subacute, or chronic stage.

Vitamins

Taking vitamins, like pyridoxine, is not advised for managing Pronator Syndrome, whether it’s in the acute, subacute, or chronic phase.

Lidocaine Patches

The application of lidocaine patches is not recommended for alleviating acute, subacute, or chronic Pronator Syndrome pain.

Ketamine

Ketamine is not suggested as a treatment for Pronator Syndrome, whether it is in the acute, subacute, or chronic state.

Treatments for Pronator Syndrome (Median Neuropathies in the Forearm)

Magnets

The use of magnets is not recommended for treating Pronator Syndrome, whether it is in the acute, subacute, or persistent stage.

Elbow and Wrist Splinting

However, using elbow and wrist splints is recommended for managing Pronator Syndrome, whether it is in the acute, subacute, or chronic phase.

 

Therapy (Active and Passive)

The importance of rehabilitation (supervised formal therapy) following a work-related injury is to focus on restoring the functional capabilities needed for the patient’s daily routines, enabling them to return to work and, as much as possible, restore the injured worker to their pre-injury state.

Active therapy requires the patient to exert internal effort to complete specific exercises or tasks, while passive therapy involves modalities administered by a therapist without the patient exerting effort. Although passive therapies are considered to expedite active therapy and achieve simultaneous objective functional gains, prioritizing active initiatives is recommended.

Encouraging patients to continue both active and passive therapy at home is crucial for ongoing progress in the healing process. Additionally, the use of assistive devices can be employed as a supplementary measure in the rehabilitation strategy to facilitate functional gains.

Therapeutic Exercise: Physical or Occupational Therapy for Acute, Subacute, Chronic, or Post-Operative Pronator Syndrome

Therapeutic Exercise: Physical or Occupational Therapy for Acute, Subacute, Chronic, or Post-Operative Pronator Syndrome is recommended for managing post-operative, chronic, subacute, or acute pronator syndrome.

Frequency/Dose/Duration – The total number of visits may range from two to three for patients with mild functional deficits to 12 to 15 for those with more severe deficits, based on ongoing objective functional improvement.

If there is evidence of improvement towards specific functional goals (e.g., enhanced grip strength, key pinch strength, range of motion, or improved capacity for work activities), more than 12 to 15 visits may be necessary to address persistent functional impairments.

A home exercise program should be integrated into the rehabilitation strategy and implemented alongside therapy.

Indications for Discontinuation: Discontinuation criteria include the absence of elbow discomfort, intolerance, ineffectiveness, or non-compliance, including failure to perform prescribed at-home exercises.

Low-Level Laser Therapy

Low-Level Laser Therapy is not recommended for Pronator Syndrome, whether acute, subacute, or chronic.

Ultrasound

Ultrasound is recommended for Pronator Syndrome, whether acute, subacute, or chronic.

Acupuncture, Biofeedback, Manipulation and Mobilization, Massage, Soft Tissue Massage, Iontophoresis, Phonophoresis

Acupuncture, Biofeedback, Manipulation and Mobilization, Massage, Soft Tissue Massage, Iontophoresis, Phonophoresis are recommended for Pronator Syndrome, which can be chronic, acute, or both.

 

Surgery of Pronator Syndrome (Median Neuropathies in the Forearm)

For pronator syndrome, a surgical release has been performed on the median nerve. Surgery referrals may be necessary for patients displaying significant warning signs, such as compressive neuropathy following an acute fracture, or those who haven’t improved with non-surgical treatments like wrist splints.

The decision for surgery depends on the established diagnosis of symptoms. Providing counseling on potential outcomes, risks, benefits, and especially expectations is crucial when contemplating surgery.

It’s essential to set preoperative expectations, emphasizing the need to adhere to the rehabilitative exercise regimen and manage post-operative pain. To prevent frozen shoulder (adhesive capsulitis), post-operative range-of-motion exercises should target the elbow, wrist, and shoulder.

Surgical Release for Treatment of Subacute or Chronic Forearm Median Neuropathies, including Pronator Syndrome

Surgical release is recommended for individuals with subacute or chronic forearm median neuropathies not responding to non-operative therapy. Urgent or emergent cases, like acute fracture-related compression syndrome or compartment syndrome with persistent signs of nerve damage, are also advised for surgery.

Indications include forearm symptoms of median neuropathy, significant loss of function evidenced by activity limitations due to nerve entrapment, and the patient’s unresponsiveness to nonoperative treatment, typically lasting three to six months.

Patients should be compliant with therapy, wear failing wrist splints, and avoid aggravating exposures. Those experiencing persistent symptoms, disease progression, or functional impairment may be surgical candidates sooner. Surgeons often require positive electrodiagnostic testing for surgery consideration.

The rationale for the recommendation is based on clear evidence of median neuropathy, positive electrodiagnostic testing, and concrete proof of loss of function. Surgery is advised for a limited number of cases.
