摘要

INTRODUCTION: Several reports indicated that interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF- alpha) play important regulatory roles in bone remodeling and homeostasis. In addition, receptor activator of nuclear factor-kappaB ligand (RANKL) and osteoprotegerin (OPG) have been shown to be important regulators of osteoclastogenesis during bone remodeling, and their expressions were examined during fracture healing in a mouse model of tibial fracture. However, studies linking RANKL, OPG, IL-6 and TNF-alpha in patients with head injury and fracture are lacking. PATIENTS AND METHODS: Within the first few hours of admission to hospital and at 4, 8, and 12 weeks after the injury, we evaluated changes in serum levels of RANKL, OPG, IL-6 and TNF-alpha in 24 male patients with a concomitant head injury and fracture and in 26 male patients with fracture only. These levels were compared with those found in 36 healthy controls. RESULTS: The RANKL/OPG ratios were found to significantly lower in patients with a concomitant head injury and fracture than in the controls immediately after admission and at 4, 8, and 12 weeks after the injury. In addition, RANKL/OPG ratios were significantly lower in patients with a concomitant head injury and fracture than in those with fracture at 8 and 12 weeks after the injury. The serum IL-6 levels were significantly higher in patients with a concomitant head injury and fracture than in the controls upon admission, and at 4, 8, and 12 weeks after the injury. Moreover, the serum IL-6 levels were significantly higher in patients with a head injury and fracture than in those with just a fracture at 4, 8, and 12 weeks after the injury. CONCLUSIONS: Based on these changes in the profiles of RANKL, OPG, and IL-6 and the RANKL/OPG ratio, altered repair of a fracture can occur in patients with a concomitant head injury and fracture.
