Delayed Union of Scaphoid Fracture and Effectiveness of Pulsed Electromagnetic Fields: A Case Report and Review of the Literature

: Fractures of the scaphoid are the most common fractures of the carpal bones. Because of the distal perfusion of the bone, there is a great chance to present complications such as avascular necrosis, delayed union of the fracture and subsequently, early osteoarthritis (up to 32%). For those reasons, the treatment of scaphoid fractures remains a challenge. Pulsed electromagnetic fields (PEMF) have been used for decades as an alternative option in delayed bone healing fractures with good results. However, to the best of our knowledge, there are scarce reports, if any, on scaphoid fractures. The objective of this case report was to show delayed union fracture as a common complication of scaphoid fracture and to postulate PEMF as an effective treatment option for such a condition, reflected by our clinical and radiological evaluations and supported by a thorough review of the literature. The patient received 20 sessions of PEMF, using the QS Magneto therapy device®, with a dose of 20Hz-50Gauss-20 minutes, 5 times a week for 4 weeks. PEMF could recover delayed nonunion of scaphoid fracture and decreased pain as evaluated clinically and radiologically in our case report.
