Methods and results

Retrospective analysis was carried out for consecutive humeral roddings for severe OI in last 3 years. Surgical technique for all humeri included retrograde telescopic nailing (female or both of FD or TST rods) with entry from olecranon fossa, exploration of radial nerve followed by osteotomies. Deformities were quantified and sub-classified as per level of deformity). Variables such as number of osteotomies, radiological union, intraoperative and postoperative complications, improvement in ROM and subjective patient satisfaction were recorded. Total 18 humeri in 12 patients with type III OI (except 1) with mean age of 8.9 years underwent nailing. All patients achieved radiological union at 6–10 weeks. Total 8 complications (44.4 %) were reported within mean 8.4 months follow up. Four segments (22.2 %) had intraoperative fractures at distal third of the humerus while negotiating the nail. Significantly higher intraoperative complications were encountered in humeri fixed with both components combined and upper third level deformities, deformities > 900 and more than 2 osteotomies. Other complications were prominent implant at upper end (2) with growth and one each of contralateral fracture and distal humeral varus. All patients reported improvement in ROM and functional status.
