LOCAL DISTAL RADIUS BONE GRAFT VS. ILIAC CREST BONE GRAFT FOR SCAPHOID NON-UNION: A COMPARATIVE STUDY

European Federation of National Associations of Orthopaedics and Traumatology (EFORT) - 12th Congress



Abstract

Introduction

Scaphoid nonunions remain controversial with regard to optimal management. The objective of this article is to compare our clinical experience in the treatment of patients with scaphoid nonunion using distal radius non vascularised bone graft with that of iliac crest bone graft.

Material & Methods

We conducted a prospective randomized study comparing the clinical, functional and radiographic results of 42 patients treated for scaphoid nonunion using a non-vascularised bone graft from the dorsal and distal aspect of the radius (group I), relative to 46 patients treated by means of a conventional non-vascularised bone graft from the iliac crest (group II). All nonunions were stabilized with single Herbert screw.

Results

Bone fusion was achieved in 87.1% of group I and 86.5% of group II patients. Functional results were good to excellent in 76.0% of the patients in group I and 72.5% in group II. The average grip power, as well as wrist flexion and extension were similar in both groups. However, the donor site morbidity was much higher in group II (4 cases of hematoma, 6 cases of chronic pain and 1 anterior superior iliac spine avulsion) fracture. No complication was seen in group I.

Conclusion

We conclude that nonvascularized distal radius bone grafting yields similar union rate as well as functional outcome as compared to iliac crest bone graft with no donor site morbidity.
