Keywords: Cubital tunnel syndrome, in-situ decompression, medial epicondylectomy.


Objectives: This study aims to compare the clinical and functional outcomes of simple in-situ decompression and partial medial epicondylectomy for the treatment of idiopathic cubital tunnel syndrome (CuTS).

Patients and methods: Between March 2014 and December 2016, 71 patients (31 males, 40 females; mean age 46.7 years; range, 38 to 62 years) with CuTS scheduled to undergo simple in-situ decompression (group 1) or partial medial epicondylectomy (group 2) were prospectively reviewed. All patients were analyzed with clinical examination (Tinel sign, Froment’s and Wartenberg’s signs, elbow flexion test, subluxation), and McGowan scores before and after surgery. Final outcomes were reviewed with Wilson and Krout grading system.

Results: There was no significant difference between the study groups in regard to Wilson and Krout grading and McGowan scores postoperatively. Group 1 had significantly better grip and key pinch strength values compared to group 2 at the final follow-up control.

Conclusion: In-situ decompression and partial medial epicondylectomy represent efficient and safe methods for the treatment of idiopathic CuTS. When their efficiency is compared, in-situ decompression had better grip and key pinch strength values and more excellent outcomes compared to partial medial epicondylectomy.
