Ulnar Superficial Slip Resection for Resistant Trigger Finger: A Minimally Invasive Technique.

Primary trigger finger is a common hand disorder for which nonoperative treatment or release of A1 pulley is usually effective. For resistant or recurrent cases, there are different surgical techniques including partial or complete opening of A2 pulley, reduction tenoplasty, and resection of the ulnar slip of the flexor digitorum superficialis tendon. Here, we present our minimally invasive technique for ulnar superficial slip resection surgery. Our indications are the patients with persistent residual proximal interphalangeal joint contracture after A1 pulley release and also the recurrent cases. Then, we report the clinical outcomes of our patients operated using this technique.
