The Use of A Solitary Multi-Planer Herbert Cannulated Bone Screw Osteosynthesis for The Treatment of Mandibular Angle Fracture.

Abstract

This study aimed to evaluate the clinical and radiographic performance of a single Herbert bone screw in the treatment of mandibular angle fractures. A prospective case series clinical trial enrolling a sample of patients with unilateral isolated mandibular angle fractures was implemented in this study. The primary outcome variable was the fracture healing with postoperative stability. The secondary outcome was the incidence of postoperative complications. All of the recorded data were documented, tabulated, computed, and analyzed. Statistical significance was set at 5% level. Twenty patients were selected. Neither major nor minor clinical complication was reported. Only one case showed slight interfragmentary mobility in the first follow-up period, which improved spontaneously in the sixth postoperative week. A statistically significant gain in the mean bone density across the fracture line was calculated. These favorable clinical and radiographic outcomes may conclude that the utilization of a solitary Herbert cannulated bone screw osteosynthesis provides a successful, economic, minimally invasive and predictable treatment modality for the treatment of mandibular angle fractures.
