Background: Vascularized periosteal graft have demonstrated a tremendous bone healing capacity in children. The objective is to report outcomes on the use of vascularized tibial periosteal graft (VTPG) during bone reconstruction in a series of children with complex bone healing problems.
Patients and methods: Cases were collected retrospectively since May 2013 to May 2019, excluding cases of congenital pseudarthrosis of the tibia. Mean age at surgery was 12.8 (range 11-18) years. Indications included treatment of recalcitrant bone nonunion and the prevention of bone allograft-host junction nonunion in seven and three patients, respectively. The periosteal flap, based on the anterior tibial vessels, was harvested as a free flap in six instances and as a pedicled flap in four.
Results: Mean follow-up was 25.2 months (range 8-36). The flap showed a 13.6 cm (range 9-16) and mean width 3.4 cm (range 2.7-3.9). Early bone union was achieved, initially through periosteal callus, followed by cortical union at mean times of 2 and 4 months, respectively, in nine cases. The flap was not successful in a patient with severe comorbidities. No donor site complications were registered.
Conclusions: VTPG was fast and high effective for the treatment complex bone nonunion or the prevention of allograft nonunion in children.
