The vascularized fibular periosteal flap has been recently described and showed solid angio and osteogenic features. We report the use of a free vascularized fibular periosteal transplant in the treatment of a El-Rosasy-Paley Type III congenital pseudarthrosis of the tibia in a 7-year-old boy, with a prior unsuccessful surgery at the age of three. The contralateral fibular periosteum was used to replace two-thirds of the hamartomatous tibial periosteum. We did not proceed to debriding the focus of the pseudarthrosis nor addressed the tibial recurvatum or revised the previous tibial rod. Consolidation was achieved radiologically at 3 months, allowing for the tibial rod to be removed. One year postoperatively, the patient ambulated without the use of a protective orthesis and resumed his sports practice. This novel pathogenesis-based technique showed promising results and a prompt healing of such a difficult orthopedic condition.

Agreement on the assessment of metastatic spine instability is moderate. The SINS can help improve communication among clinicians in oncology care.

Our findings indicate that a BMCSs loaded bone matrix scaffold is capable of stimulating bone regeneration more effectively than isolated core decompression or in association with an acellular scaffold in a preclinical femoral head osteonecrosis model in sheep.

The TS was not highly accurate for predicting survival in patients with VM, treated or not surgically, and it was particularly imprecise in patients with an intermediate score (9-11 points) and those with breast cancer, so it is possible that the TS currently has a poor external validity.
