BACKGROUND About 2 000 patients annually incur a fractured scaphoid in Norway. Assessment and diagnosis can be difficult, and fractures are overlooked.
Scaphoid fractures have traditionally been cast-immobilised, but for the last decade screw fixing has been used increasingly, and offers hope of a higher
healing frequency and improved function. Some scaphoid fractures are not diagnosed in the acute phase and some do not heal after treatment. Patients may
then end up with painful pseudarthrosis. The purpose of this article is to provide an overview of the assessment, treatment and outcomes of scaphoid
fractures.
METHOD The article is based on literature searches in PubMed and the authors' own clinical experience.
RESULTS Primary diagnosis of scaphoid fractures and subsequent plaster cast immobilisation yield very good clinical results. Surgery should be limited to
displaced fractures, fractures forming part of more extensive wrist injuries and exceptional other cases. Results comparable a quality equivalent to cast
immobilisation are achieved by experienced surgeons in this area. Untreated scaphoid fractures often result in painful pseudarthrosis with subsequent
abnormal position of the carpal bones and secondary arthrosis. This outcome can be counteracted by surgery on old fractures with bone grafting, internal
fixation and cast immobilisation.
INTERPRETATION Norwegian procedures for treating scaphoid fractures/pseudarthrosis are consistent with internationally documented good practice.
Assessment of wrist pain following falls can be improved by conducting clinical tests for scaphoid fracture and radiology with four wrist projections. In the
event of clinical suspicion, but no X-ray findings, the patient should be referred for a CT or MRI scan.
