Both autogenous cancellous bone and titanium mesh cages (TMCs) are commonly used for anterior column reconstruction. However, TMCs have gained more attention due to their stability, biocompatibility, and competent mechanical properties. This study compared the clinical and biomechanical performance of autogenous bone and TMCs in CS patients.<h4>Methods</h4>We retrospectively reviewed 117 CS patients with hemivertebra between T10 and L2 who underwent posterior hemivertebra resection, short segmental internal fixation (2-4 segments) and anterior column reconstruction froJournal of orthopaedic surgery and researchAnterior column reconstruction with titanium mesh cage versus autogenous cancellous bone graft for short segmentation fusion after hemivertebra resection in the thoracolumbar spine: a retrospective and finite-element study.PMC126399342022-PUMCH-B-0012023YFC2507700Li ZHan BZhang JWang SDu YfalseAnterior column reconstruction with titanium mesh cage versus autogenous cancellous bone graft for short segmentation fusion after hemivertebra resection in the thoracolumbar spine: a retrospective and finite-element study.<h4>Background</h4>Posterior hemivertebra resection, combined with anterior column reconstruction by short segmental fusion, is a widely accepted approach in the treatment of congenital scoliosis (CS) caused by hemivertebra.
