title: Pediatric Trigger Finger due to Osteochondroma: A Report of Two Cases.
abstract: Background:The trigger finger is characterized by the painful blocking of finger flexor tendons of the hand, while crossing the A1 pulley. It is a rare disease in children and, when present, is usually located in the thumb, and does not have any defined cause.Methods:We report 2 pediatric trigger finger cases affecting the long digits of the hand that were caused by an osteochondroma located at the proximal phalanx. Both children held the diagnosis of juvenile multiple osteochondromatosis. They had presented at the initial visit with a painful finger blocking. Surgical approach was decided with wide regional exposure, as compared with the trigger finger traditional surgical techniques, with the opening of the A1 pulley and the initial portion of the A2 pulley, along with bone tumor resection.Results:Patients evolved uneventfully, and recovered the affected finger motion.Conclusion:It is important to highlight that pediatric trigger finger is a distinct ailment from the adult trigger finger, and also in children is important to differentiate whenever the disease either affects the thumb or the long fingers. A secondary cause shall be sought whenever the long fingers are affected by a trigger finger.
