Prospective randomized comparison of quality of regenerate in distraction osteogenesis of ring monolateral fixator in patients with infected nonunion of the tibia using digital radiographs and CT.

Aims: In this randomized study, we aimed to compare quality of regenerate in monolateral circular frame fixation in 30 patients with infected nonunion of tibia.

Patients And Methods: Both groups were comparable in demographic and injury characteristics. A phantom (aluminium step wedge of increasing thickness) was designed to compare the density of regenerate on radiographs.
