Introduction

The purpose of our study was to retrospectively analyze our patients who were treated for FH and PFFD by means of guided growth temporary Hemiepiphysiodesis.

We sought to determine the effectiveness of the procedure, as well as its success rates, complications, and rebound phenomena.

Aim: To report our experience and early results with flexible nailing for unstable or irreducible displaced proximal humeral fractures in children.

Material & methods: Between 1997 & 2004, 15 children with unstable or irreducible displaced fractures of the proximal humerus were treated with closed/open reduction and flexible IM nailing. There were 10 boys and 5 girls. The median age of the patients was 12.5 years (9–15). Thirteen children had a Salter – Harris II, Neer grade III/IV fracture and 2 children had metaphyseal fractures. The outcome assessment was performed using the shoulder score, clinical and radiological parameters.

Results: All fractures united. None of the patients had a clinically significant malunion/shortening. Three patients had irritation at the nail insertion site. One patient had a transient radial nerve neurapraxia. There were no other operative or postoperative complications. The flexible nails were removed at a median time of 6 months (1.5–10) in 12 patients and 3 patients are awaiting removal. At a median follow-up of 30 months (4–66) all patients had a normal or near normal glenohumeral motion, full strength and all reported regaining full pre-injury functional use of the involved extremity.

Conclusion: Flexible nailing can be used safely to maintain reduction in unstable or irreducible displaced fractures of the proximal humerus and allows early return to normal activities and function with minimal complications. This treatment is also useful in older children who have minimal remodelling potential.
