Aims: To study the clinical and radiological signs of healing, functional outcome and incidence of complications with this method

Introduction: Humerus is the single bone occupying arm. With options and controversies of operative and conservative management, management of humerus shaft fractures with closed nailing with TENs has shown better outcome.

Materials and Methods: We have done prospective study of 25 patients with humerus shaft fractures operated by intramedullary fixation by TEN nails with follow up of 6 to 30 months. Final outcomes were assessed per ASES score.

Results: Fracture union: 92% of patients showed evidence of union on or before 20 weeks. Functional outcome: was excellent to good in 92% patients according to ASES score with 96% patients returned to original work in follow up.

Conclusion: Humerus intramedullary TENs nailing may be considered a

procedure of choice in fractures middle two third of shaft of humerus, since

closed it preserves the fracture hematoma, is less invasive, has less complication

rates & gives solid bony union & good functional outcome.
