Abstract
The aim of this study was to assess the effect of malunion of scaphoid fractures on the clinical outcome at 1 year. Forty-two consecutive patients with united scaphoid waist fractures which had been treated non-operatively underwent longitudinal CT scans to confirm union and assess malunion at 12 to 18 weeks after injury. A blind clinical assessment was made and the Patient Evaluation Measure (PEM) and DASH questionnaires were completed by all the patients 1 year after injury. The group consisted of 38 men and four women with a mean age of 31 years at the time of injury. Correlation analysis revealed no significant relationships between any of the outcome measures (range of motion, grip strength and PEM and DASH scores) and any of the three measures of malunion (height-to-length ratio, the dorsal cortical angle and the lateral intra-scaphoid angle).
