Use of Vascularized and Non-vascularized Bone Grafting in Scaphoid Non-union: A Prospective Randomized Control Trial
Description
This presentation led by Ruby Grewal discusses a clinical trial comparing vascularized versus non-vascularized bone grafting techniques for treating scaphoid nonunions. Grewal opens the session by thanking attendees and confirming screen sharing of a PowerPoint presentation. She explains the rationale behind the study, addressing inconsistencies in existing literature regarding the effectiveness of vascularized grafts. The trial aims to assess patient outcomes and union times using standardized fixation methods.
Approximately 50 patients were enrolled in the study, with strict inclusion criteria, excluding those with advanced degeneration or known avascular necrosis (AVN) to maintain a homogeneous cohort. The results indicated that 95% of patients with the vascularized graft achieved union compared to 90% in the iliac crest group, although the difference was not statistically significant. Notably, smoking emerged as a significant confounder in the study's outcomes; smokers were found to be significantly less likely to achieve union across both graft types. Post-adjustment for smoking, vascularized grafts demonstrated a notable efficacy advantage, reinforcing the importance of considering lifestyle factors in surgical outcomes.
