THE MANAGEMENT OF ISOLATED COMPRESSIVE FRACTURES OF DISTAL RADIUS FOSSAS

Abstract

Introduction: Isolated compressive fractures of the scaphoid and lunate fossa of the distal radius are rare injuries and their closed reduction is almost impossible. Frequently the displacement becomes accepted and conservative treatment was applied which in the long-term could have catastrophic consequences concerning the fate of articular cartilage.

Material and Methods: Seven patients (6 males and 1 female) of mean age 30 years old (range 18–42) were studied with compressive fracture of scaphoid (4 patients) or lunate (3 patients) fossa. All patients (except one with compressive fracture of the lunate fossa who was treated early), were initially treated conservatively. Mean delay of surgical treatment was 36 days (3 patients) while two patients were operated 2 and 2, 5 years postinjury. One patient with fractured lunate fossa had concomitant fracture of the lunate. The vast majority of the patients underwent supplementary imaging techniques (CT scan, MRI, 3D-CT scan). The majority of patients were approached both intraarticularly and extraarticularly.

Results: Results were estimated after an average follow-up of 12 months (range, 6 months – 3 years) according to clinical and radiological criteria. Six patients revealed excellent or good result while one had a fair result.

Conclusion: In conclusion, operative treatment of these intraarticular fractures should be attempted independently of the time elapsed from injury on the premise that there are no arthritic changes and an adequate pre-operative planning has done.
