Cubital tunnel syndrome is a common upper extremity compressive neuropathy. Recalcitrant cubital tunnel syndrome poses diagnostic and treatment challenges. Potential etiologies of persistent or recurrent symptoms after surgical treatment include an inaccurate preoperative diagnosis, incomplete nerve decompression, iatrogenic injury, postsurgical perineural adhesions, irreversible nerve pathology, or conditions associated with secondary nerve compression. Confirmation of recalcitrant ulnar nerve pathology relies on a thorough history to consider symptoms and chronology, careful examination to quantify nerve function and to assess for focal nerve provocation, and objective testing to highlight a possible nerve lesion such as ultrasonography and electrodiagnostic testing. Conservative treatment may provide symptomatic relief; however, surgical management such as revision neuroplasty, neurolysis, nerve reconstruction, and/or anterior transposition may be indicated. Optimizing the biology of the local nerve environment is critical. No surgical treatment procedure has shown superiority over another; however, individualized treatment is emphasized to improve symptoms and maximize nerve recovery potential.
