INTRODUCTION Chest wall reconstruction in children after large resection of tumors may be performed with rigid or soft materials. Cementoplasty is commonly used with the ‟Sandwich‟ method i.e. gore-tex meshes surrounding both faces of the cement. HYPOTHESIS Is antibiotic loaded single-side gore-tex ‟Tartine‟ methyl-methacrylate cementoplasty an interesting alternative to the double-side ‟sandwich‟ method for chest wall reconstruction? MATERIAL AND METHODS Consecutive patients who were treated from 2011 to 2023 in our hospital were included. RESULTS Among the tenchildren treated with a median 5.6 years follow-up, there were no surgical complications related to the reconstruction, loss of function, infections, post operative complications (versus 22.7% in meta-analysis encompassing the 50 rigid reconstructions reported worldwide) nor scoliosis (versus 25%). Three patients have an asymmetric chest wall appearance. DISCUSSION ‟Tartine‟ cementoplasty is a simple, low-cost technique for pediatric chest wall reconstruction. It is well tolerated and checks key demands for chest wall reconstructions. LEVEL OF EVIDENCE IV; retrospective case series.
