Partial Union of Acute Scaphoid FracturesFrom the Departments of Trauma and Orthopaedic Surgery and Diagnostic Imaging, Queen’s Medical Centre, University Hospital, Nottingham, UK Correspondence: Professor T. R. C. Davis, Department of Trauma and Orthopaedic Surgery, Queen’s Medical Centre, University Hospital, Nottingham, NG7 2UH, UK. Tel.: +44 1159249924x44337; fax: +44 1159209921. E-mail: tim.davis{at}qmc.nhs.uk Sixty-six patients with acute scaphoid fractures were treated non-operatively in a below elbow plaster for 8 to 12 weeks and underwent CT scans along the longitudinal axis of the scaphoid at 12 to 18 weeks. These scans showed that 14 fractures had not united and that 30 had united throughout the whole cross-section of the scaphoid. The other 22 had partially united with bridging trabeculae in some areas of the cross-section. These 22 partial unions were graded as 0% to 24% union (0 cases), 25% to 49% union (5 cases), 50% to 74% union (7 cases), and 75% to 99% union (10 cases). The 12 patients who had less than 75% fracture union were followed-up further and nine underwent another CT scan at 23 to 40 weeks after the initial injury. These showed union across the whole of the cross-section of the fracture in seven cases and 75% to 99% union in the other two cases, who had full and painless wrist function. We conclude that partial union of the scaphoid is a common occurrence but, in most cases, it progresses to full union without the need for prolonged plaster immobilization.
