Abstract
Purpose of study:
The treatment goals in diaphyseal radius fractures are to regain and maintain length and rotational stability. Open reduction and plating remains the gold standard but carries the inherent problems of soft tissue disruption and periosteal stripping. Intramedullary nailing offers advantages of minimally invasive surgery and minimal soft tissue trauma. The purpose of this study is to describe the results of locked intramedullary nailing for adult gunshot diaphyseal radius fractures.
Methods:
A retrospective review of clinical and radiological records was performed on patients with intramedullary nailing of isolated gunshot radius fractures between 2009 and 2013.
Results:
Twenty-two nails were inserted in 22 patients, all males with a mean age of 28.9 years (range 19–40). Follow-up was for an average period of 11 weeks (range 6–24). One patient had a median nerve palsy and 2 a posterior interosseous nerve palsy pre-operatively. All operations were performed within 3 to 12 days of the injury. No primary bone grafting was performed.
All fractures united with the index procedure. Average time to union was 10 weeks (range 8–24). Fourteen patients (64%) had their radial bow restored and maintained; these patients had minimal comminution in the middle to distal third of the radius. The bow could not be satisfactorily restored in severely comminuted fractures in the proximal third of the radius.
Using the Anderson classification outcome was excellent in 14 patients (64%), satisfactory in 6 (27%) and unsatisfactory in 2 (9%). There were no complications associated with the surgery and one patient required nail removal for implant migration.
Conclusion:
Intramedullary nail fixation of gunshot radius fractures has shown promising results in our hands with no significant complications. The fracture site and zone of comminution directly influenced our ability to restore radial bow.
