Description

A 53-year-old female was referred to our department due to resistance which developed after two years of conservative therapy for lateral epicondylitis of the humerus, which had become intractable. Preoperative MRI findings showed chondrolysis and rupture of the wrist extensor tendon at the level of the right lateral epicondyle. Surgical treatment was planned and the ruptured tendon of the extensor carpi radialis brevis muscle was sutured.<br>After simple suture of the wrist extensors, hydrarthrosis recurred approximately eight weeks after surgery. Re-suturing was performed with the modified Nirschl technique using the Krackow stitch and a suture anchor. The patient's symptoms improved following this procedure. Although many patients respond well to conservative therapy for lateral epicondylitis of the humerus, some develop resistance to therapy and their condition becomes intractable. In particular, repeat local steroid injections can cause tendon rupture; therefore, it is important to emphasize caution regarding conservative treatment with steroid local injections.
