Simple decompression vs. subcutaneous anterior transposition of the ulnar nerve: the 2025 update on the optimal treatment for cubital tunnel syndrome

Year: 2025

Type: article

Abstract: Purpose This 2024 update aims to compare the clinical outcomes, recurrence, and revision rates between simple decompression (SD) and subcutaneous anterior transposition (SAT) of the ulnar nerve for treating cubital tunnel syndrome (CuTS). Materials and Methods A systematic review of articles from PubMed, Scopus, and Google Scholar was performed in accordance with PRISMA guidelines. We selected all English-language comparative studies published from January 2000 to June 2024, comparing SD and SAT concerning postoperative outcomes of surgical treatment for cubital tunnel syndrome. Results Ten articles met the inclusion criteria. We found no statistical difference in the clinical outcomes of SD and SAT. Two studies indicated SD was superior to SAT. Four studies concluded that both techniques were equally effective for CuTS treatment. Three studies were inconclusive, and one study reported in situ decompression as inferior to subcutaneous anterior transposition, with a high recurrence rate. Conclusion As of 2025, the surgical approach to cubital tunnel syndrome remains consistent with current practice. Both simple decompression and subcutaneous anterior transposition of the ulnar nerve continue to demonstrate good clinical outcomes. Although simple decompression may be associated with higher rates of recurrences and revision surgeries, no clear superiority of one technique over the other has been established.
