This retrospective study, conducted at a referral center in eastern India, included 132 patients with aseptic humeral shaft nonunion from 2002 to 2020.

Surgical techniques involved excising fibrous and unhealthy tissue, compressing the nonunion site, decorticating, shingling, autologous bone grafting, and stable fixation with dynamic or locking compression plates.
