New York State Medical Treatment Guidelines for Ulnar Nerve Entrapment at the Wrist in workers compensation patients

The guidelines presented by the New York State Workers Compensation Board provide fundamental principles for addressing Ulnar Nerve Entrapment at the Wrist. These directives are crafted to assist healthcare professionals in identifying appropriate therapeutic approaches within the context of a comprehensive assessment.

Healthcare professionals specializing in managing Ulnar Nerve Entrapment at the Wrist can rely on the guidance outlined by the Workers Compensation Board to make well-informed decisions about the most suitable therapeutic methods for their patients.

It is essential to underscore that these guidelines are not intended to replace clinical judgment or professional expertise. The ultimate decision regarding the management of Ulnar Nerve Entrapment at the Wrist should involve collaboration between the patient and their healthcare provider.

 

Ulnar Nerve Entrapment at the Wrist

 

Diagnostic Studies

Electrodiagnostic Studies

Recommended to confirm clinical suspicion of ulnar nerve entrapment at the wrist. Electrodiagnostic studies should be conducted by well-trained electrodiagnosticians, preferably certified by the American Board of Electrodiagnostic Medicine.

MRI or Ultrasound

Not recommended for diagnosing ulnar nerve entrapment at the wrist. However, recommended for suspected soft-tissue masses, with MRI being preferable for conditions like ganglion cysts.

CT

Recommended to diagnose ulnar nerve entrapment at the wrist if a hook of the hamate fracture is suspected. CT is preferable for evaluating fractures.

 

Medications

For most patients, ibuprofen, naproxen, or other older generation NSAIDs are recommended as first-line medications. Acetaminophen may be an alternative for those not suitable for NSAIDs, though NSAIDs are generally more effective.

Non-Steroidal Anti-inflammatory Drugs (NSAIDs) for Ulnar Nerve Compression

Recommended for acute, subacute, or chronic ulnar nerve compression at the wrist. Over-the-counter agents are suggested first. Use should be as needed and discontinued upon symptom resolution, lack of efficacy, or development of adverse effects.

NSAIDs for Patients at High Risk of Gastrointestinal Bleeding

Recommended for concomitant use with cytoprotective drugs for patients at high risk of gastrointestinal bleeding. Consideration is especially important for at-risk patients like those with a history of prior gastrointestinal bleeding, elderly individuals, diabetics, and smokers.

NSAIDs for Patients at Risk for Cardiovascular Adverse Effects

Patients with cardiovascular disease or risk factors should discuss the risks and benefits of NSAID therapy. Acetaminophen or aspirin is recommended as the first-line therapy. If NSAIDs are needed, non-selective ones are preferred over COX-2 specific drugs. To minimize counteraction with aspirin, NSAIDs should be taken at least 30 minutes after or 8 hours before daily aspirin.

Acetaminophen for Ulnar Nerve Compression Pain

Recommended for pain associated with ulnar nerve compression at the wrist, particularly for patients with NSAID contraindications. Usage should be per manufacturer’s recommendations, and hepatic toxicity risks should be considered.

Opioids

Not recommended for acute, subacute, or chronic ulnar nerve entrapment. However, recommended for limited use (not exceeding seven days) for postoperative pain management, especially nocturnally, as an adjunct to more effective treatments.

Glucocorticosteroids – Oral and/or Injected

Not recommended for the treatment of acute, subacute, or chronic ulnar nerve compression at the wrist.

 

Ulnar Nerve Compression: Splinting and Rehabilitation

Splinting

Neutral Wrist Splinting

Recommended as the first-line treatment for acute, subacute, or chronic ulnar nerve compression at the wrist.

 

Rehabilitation

Rehabilitation for work-related injuries should aim to restore functional ability for daily and work activities, striving to return the patient to pre-injury status. Active therapy involves internal effort by the patient, while passive therapy relies on modalities delivered by a therapist. Emphasis should be on active interventions, with both active and passive therapies continued at home to maintain improvement levels. Assistive devices may be included to facilitate functional gains.

Therapy – Active

Therapeutic Exercise

Not recommended for acute ulnar nerve compression at the wrist but recommended post-operatively. For subacute and chronic ulnar nerve compression with functional deficits, therapeutic exercise is recommended.

Rationale for Recommendation: Exercise is generally not indicated acutely; however, it may be necessary in recovery or post-operative phases. Functional goals include increased grip strength, key pinch strength, range of motion, and advancing work abilities. The frequency/dose/duration can vary based on the severity of deficits, with a home exercise program as part of the rehabilitation plan.

 

Therapy – Passive

Ice – Self-application

Recommended for the treatment of acute, subacute, or chronic radial nerve entrapment.

Heat – Self-application

Recommended for the treatment of acute, subacute, or chronic radial nerve entrapment.

Manipulation/Mobilization

Not recommended for the treatment of acute, subacute, or chronic radial nerve entrapment.

Iontophoresis

Not recommended for the treatment of acute, subacute, or chronic radial nerve entrapment.

Massage, Friction Massage

Not recommended for the treatment of acute, subacute, or chronic radial nerve entrapment.

Acupuncture

Not recommended for the treatment of acute, subacute, or chronic radial nerve entrapment.

Activity Modification

Recommended, particularly avoiding significant localized mechanical compression of the nerve or using the hand as a hammer, for the treatment of ulnar nerve compression at the wrist.

 

Surgery

Surgical Decompression

Recommended for subacute or chronic ulnar nerve compression at the wrist after the failure of non-operative treatment or in the presence of space-occupying lesions.

Rationale for Recommendation: It is recommended for select patients who have not responded to other non-operative treatments or when space-occupying lesions are present. It may also be preferable in individuals with diabetes mellitus.
