BACKGROUND AND OBJECTIVEThe most common type of fracture in the upper extremity is the distal radial fracture. Such fractures carry a high risk of creating complex regional pain syndrome, type I (CRPS-1). This study was designed to further understand the risk of CRPS-1 among patients with these fractures.
METHODSSubjects were 477 patients with a distal radial fracture, treated surgically between July of 2010 and April of 2013. The patients were assessed for symptoms of CRPS-1 at six, 12 and 24 weeks after surgery. At follow-up, 42 patients with were diagnosed with CRPS-1. These cases were reviewed for distinguishing characteristics, including age, gender, body mass index, type of fracture, energy of trauma, number of trial reductions, type of surgery, and duration of immobilization.
RESULTSA bivariate relationship analysis indicated that six percent of male, and 11% of female, patients had developed CRPS-1 (P=0.02). Those with CRPS-1 were older and more likely to have sustained a high-energy injury and to have a comminuted fracture (P<0.02, P<0.02 and P<0.01, respectively). Multivariate logistic analysis revealed that female gender, a severe type of fracture, and a high-energy injury contributed significantly to the development of CRPS-1.
CONCLUSIONThis study of patients with surgically treated distal radial fractures found that gender, high-energy injury and a severe fracture type are risk factors for developing CRPS-1.
