    Abstract:
    PURPOSE: To evaluate clinical and radiological outcomes after surgical treatment of scaphoid nonunion in adolescents with a vascularized thumb metacarpal periosteal pedicled flap (VTMPF). METHODS: Twelve patients younger than 18 years with scaphoid nonunion, who underwent a VTMPF procedure without bone grafting, were included for this prospective cohort study, at a mean follow-up of 10.2 months. Patients were operated on by 3 different hand surgeons at 3 hand surgery institutions. All patients received a VTMPF, but with different scaphoid internal fixation modalities, in 10 cases using 1 or 2 retrograde 2-mm headless compression screws and in 2 cases without internal fixation. RESULTS: In 11 boys and 1 girl, the mean age was 15.6 years. There were 1 type D1 nonunions (Herbert classification), 6 type D2, 2 type D3, and 2 type D4. Six patients had previously undergone an unsuccessful surgical attempt to treat their nonunion. The mean anterior bone defect was 3.5 mm in length. The patients experienced no postoperative complications. Successful consolidation was achieved in all cases, with 79% cross-sectional trabecular bridging at 12 weeks. Pain subsided after surgery and patients experienced improvements in both their Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) and Modified Mayo Wrist Score (MMWS) results. Overall, 34% and 40% gains in strength and wrist motion, relative to the contralateral normal side, were observed. CONCLUSIONS: In this study, the use of VTMPF for scaphoid nonunion in children and adolescents is associated with generally good outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
