RationaleThree-dimensional (3D) printing has attracted wide attention for its potential and abilities in the assistance of surgical planning and the development of personalized prostheses. We herewith report a unique case of chronic clavicle osteomyelitis treated with a two-stage subtotal clavicle reconstruction using a 3D printed polyether-ether-ketone (PEEK) prosthesis.Patient ConcernsA 23-year-old Chinese female presented to our clinic complaining about a progressive pain of her right clavicle for about 1 year.DiagnosesChronic clavicle osteomyelitis confirmed by percutaneous biopsy and lesion biopsy.InterventionsThis patient accepted a long-term conservative treatment, which did not gain satisfactory outcomes. Thus, a subtotal removal and two-stage reconstruction of the right clavicle with a 3D-printed polyether-ether-ketone prosthesis stabilized by screw fixation system was performed.OutcomesAt 2-year follow-up, complete pain relief and satisfactory functional recovery of her right shoulder were observed.LessonsPersonalized 3D printed prosthesis is an effective and feasible method for reconstruction of complex bone defects.Copyright © 2021 the Author(s).
