- However, recent prospective studies have called into question the clinical benefit of operative over conservative management..
- Pinpointing which specific fractures will heal or result in good clinical outcomes remains exceedingly difficult..
- While this study does not examine clinical outcomes, it focuses on the more objective measure of fracture nonunion, which have predictably poor clinical results..
- The main findings were that decreasing head-shaft angle, increasing head-shaft translation and smoking were independently predictive of nonunion and that nonunion risk was further increased when multiple of these factors were present….
