Management of Ulnar Nerve Compression

Initial Conservative Management

The American College of Rheumatology recommends initial management of ulnar nerve compression affecting the hypothenar muscles with conservative treatment, including activity modification, splinting, and physiotherapy, reserving corticosteroid injections only as a bridging option while awaiting the effect of other interventions, as long-term glucocorticoid use should be avoided 1
Avoid activities that place excessive load or repetitive pressure on the ulnar nerve distribution, particularly at the elbow and wrist, as recommended by clinical guidelines 2
A structured regimen of physiotherapy should be implemented for patients with ulnar nerve compression affecting the hypothenar muscles, including range of motion and strengthening exercises to maintain hand and wrist function 3, 2
Local application of heat before exercise may provide additional benefit for patients with ulnar nerve compression 2
Paracetamol (up to 4g/day) should be the oral analgesic of first choice due to its efficacy and safety profile, and topical NSAIDs can be effective for localized pain with fewer systemic side effects 2
For inadequate response to paracetamol, oral NSAIDs at the lowest effective dose for the shortest duration may be considered 2

Quantitative ulnar nerve monitoring using train-of-four (TOF) assessment at the adductor pollicis muscle is the most reliable method for assessing nerve function, according to the World Journal of Emergency Surgery and Anaesthesia 4, 5
MRI without IV contrast can evaluate for associated conditions and soft tissue pathology in patients with persistent symptoms and normal or nonspecific clinical findings 2
Ultrasound can assess nerve integrity with high accuracy in patients with ulnar nerve compression 2
