Abstract
Plasma spray nano-hydroxyapatite-coated titanium intramedullary implants doped either with 5% zinc, 2.5% strontium, and 2.5% fluorine ions or with 5% zinc, 5% strontium, and 2.5% silver ions were evaluated compared with plasma spray nano-hydroxyapatite-coated titanium intramedullary implant and uncoated titanium intramedullary implants for open reduction and internal immobilization in 24 clinical cases of long bone fracture repair in dogs. Fracture-healing limb outcome was evaluated clinically, that is, radiographically. Biochemical estimation of serum calcium, serum phosphorus, alkaline phosphatase (ALP), and bone markers (bone ALP [BALP] and C-telopeptide of type 1 collagen [CTX]) was carried out on 0th day, 3rd week, 6th, and 9th week postoperatively. Multi-ion-doped plasma spray nano-hydroxyapatite-coated titanium intramedullary implants were found to be superior to plasma spray nano-hydroxyapatite-coated titanium intramedullary implants and uncoated titanium intramedullary implants in terms of all the parameters studied. Using plasma spray nano-hydroxyapatite-coated titanium implants doped with multi ions, that is, 5% zinc, 5% strontium, and 2.5% silver gave the best results in fracture repair followed by the implants doped with 5% zinc, 2.5% strontium, and 2.5% fluorine ions. Earliest and excellent limb usage with no postoperative complications was the hallmark of the use of these multi-ion-doped implants with higher serum calcium, serum phosphorus, ALP, BALP, and CTX values up to 3rd postoperative week and no lameness on the 21st day.
