We present our single institution experience; 15 cases; age range 14 to 17 years. A pre sprung pectus bar is placed through a sub muscle tunnel and anchored using vertical stabilisers and wire to the ribs bilaterally using a modified Abramson technique. Bar, stabilizers and wires are removed after 24 months. Patient selection: Those with a compressible deformity, for whom a trial of removable bracing supplied by our Orthotics team had proven unsuccessful were offered surgery. Our modifications of the Abramson technique with the aim to reduce the reported incidence of skin adherence, wire breakage and bar migration will be demonstrated. Results: we report no skin adherence, three cases of wire breakage, two cases for whom outcome was impaired by bar migration and one patient who had premature bar removal due to chronic pain. No implant infection has occurred. These complications will be discussed in detail. References: Abramson H, D’Agostino et al.
