Distraction osteogenesis in combined sequential use of external fixation and nailing (lengthening and then nailing): An experimental study in rabbits.

Limb lengthening relies on the process of distraction osteogenesis. The active periosteal bone formation has been detected in clinical practice with a lengthening and then nail (LATN) technique but has not been confirmed by experimental studies to date. The aim of this study is to compare the tissue regeneration of the distraction regenerate during tibial lengthening in rabbits using a LATN technique.

Knee Joint Bone Defects: Reconstruction With Bone Transport and Arthrodesis.

Background: The increasing in primary total knee arthroplasty has led to an increase in infectious complications, revision surgery, and bone loss. Knee joint bone defects (KJBD) may be managed using bone transport and arthrodesis with Ilizarov or bone transport over nail (BTON) techniques. The aim of this study is to compare both techniques in the reconstruction of KJBDs.

A comparative study of the correction of femoral deformity between the Ilizarov apparatus and Ortho-SUV Frame.

Purposes: This study compared the six-axis external fixator Ortho-SUV Frame (OSF) and the Ilizarov apparatus (IA) in femoral deformity correction. Our specific questions were: (1) which of the fixators (OSF or IA) provides shorter period of femoral deformity correction, and (2) which of the fixators (OSF or IA) provides better accuracy of correction.

Methods: We retrospectively analysed 123 cases of femoral deformities (127 femora): 45 (47) treated with OSF (20 male and 27 female) and 78 (80) with IA (53 male and 27 female).
