Risk of nerve injury during elbow arthroscopy: ultrasonographic evaluation of preoperative patients.

Background: To clarify the real risk of nerve injury during elbow arthroscopy, the distances of the radial and median nerves to the elbow joint were investigated using ultrasonography in patients who underwent surgery.

Methods: A total of 35 patients who underwent arthroscopic surgery of the elbow were investigated. The distances of the nerves to the capsule and bony landmarks were measured using ultrasonography.

Arthroscopic Debridement for Refractory Lateral Epicondylitis Results for Substantial Improvement in Tendinosis Scores and Good Clinical Outcomes: Qualitative and Quantitative Magnetic Resonance Imaging Analysis.

Purpose: To qualify and quantify the changes in magnetic resonance imaging (MRI) signals in the extensor tendons after arthroscopic debridement for lateral epicondylitis and evaluate the association between MRI findings and temporal clinical results by comparisons between recovered and unrecovered cases.

Methods: Thirty-four patients with refractory lateral epicondylitis treated with arthroscopic debridement were divided into recovered (n = 24) and unrecovered (n = 10) groups according to the Japanese Orthopaedic Association-Japan Elbow Society score. This study included any patients who underwent both the pre- and postoperative MRI and excluded patients with a previous history of any elbow surgery.

Arthroscopic Partial Excision of the Radial Head for Advanced Rheumatoid Elbow.

We treated humeroradial joint disorder in rheumatoid elbows with arthroscopic partial excision of the radial head, in which the radial head is minimally resected under arthroscopy to ensure adequate joint space and articular congruity. To examine the effect of this method, we investigated outcomes using a retrospective case series. The hypothesis of this study was that this method decreases symptoms related to the humeroradial joint and ensures articular congruity.
