Fig. 1From: An exploratory study of gold wire implantation at acupoints to accelerate ulnar fracture healing in ratsEffect of gold wire implantation on bone regeneration in segmental ulnar bone defect. Bone defect width was obtained from radiographs of the right antebrachium, taken weekly through 8 weeks and bone regeneration in each rat was calculated as follows: bone regeneration (%) = (bone defect width at 2 weeks after surgery-bone defect width weekly)/(bone defect width at 2 weeks after surgery) × 100. Both groups showed gradual and consistent bone regeneration. From 4 weeks after gold implantation, the implanted rats showed significantly faster bone regeneration than the control rats, lasting up to 8 weeks after implantation. Data are expressed as mean ± SEM. *P < 0.05 compared with control groupBack to article page
