About

The investigators want to compare changes in cross-sectional area (CSA) of the ulnar nerve at the elbow after open release or endoscopic release.

Full description

The investigators want to compare changes in CSA of the ulnar nerve at the elbow hypothesizing that US examination is a useful tool to detect unsuccessful release and defining which technique shows the best outcome in the first year postoperatively.

The measurement of cross-sectional area (CSA) as a diagnostic tool to detect entrapments syndrome in upper limbs has already been described. US typically demonstrates an abrupt narrowing and displacement of the nerve within the tunnel, possibly in association with a thickened retinaculum or a space-occupying lesions. Previous studies prospectively compared sonographic outcomes after decompression of the median nerve at the wrist.

60 participants in 2 patient groups

Open cubital tunnel release
Other group
Description:
In situ decompression (MacKinnon and Novak 2005) is made through a 6-10 cm longitudinal incision along the course of the ulnar nerve midway between the medial epicondyle and the olecranon.
Treatment:
Procedure: Cubital tunnel release
Endoscopic cubital tunnel release
Other group
Description:
Endoscopic release follows Hoffmann's technique (Hoffmann 2006) that demonstrated the safety and efficacy of this technique in a cadaveric model and in a clinical study.
Treatment:
Procedure: Cubital tunnel release
