“…It is believed that the low silver amount in the coating is caused by a preferential sputtering phenomenon that takes place during RF magnetron sputtering. A similar observation was made in the case of Sr-containing HA coating sputter-deposited using a Sr-HA target [109].…”

“…Although screw head fractures did not occur, the HA coating peeled off several times due to the torque exerted on the screw heads by a screwdriver. Recently, mixing HA with another material 28 and bilayer technique 29,30 were also used to reduce detaching coating layer. To improve the wear resistance, additional coatings of polylactide-co-glycolide are being considered; these coatings, we think, could actually be more applicable to plates on which bending occurs.…”

Radiological, histological, and hematological evaluation of hydroxyapatite‐coated resorbable magnesium alloy screws placed in rabbit tibia

Titanium (Ti) screw has excellent mechanical property, and osseointegration capacity. However, they require surgery for removal. In contrast, polymer screws are resorbable, but they have poor mechanical properties. In this research, magnesium alloy screws (WE43: Mg-Y-Nd-Zr) that have advantages of titanium and polymer were manufactured. In addition, to increase biocompatibility and control degradation rate, the Mg alloy was coated with hydroxyapatite (HA). Torsion test and corrosion test were performed in vitro. For clinical, radiological and histological evaluation, on the eight rabbits, two HA-coated screws were installed in left tibia, and two noncoated screws were installed in right tibia. Each four rabbits were sacrificed 6 and 12 weeks postoperatively. For hematological evaluation, the same type of screws were installed on both legs. Complete blood count (CBC), Mg concentrate were sampled from the ear central artery on the operation day for a control point, and at 1, 2, 4, 6, 8, and 12 weeks. Mg alloy screws have no differences of biocompatibility according to the HA coating. However, resorption of screw was slower in case of the HA coating. The hematological problem related releasing of Mg was not found. The results suggest that Mg alloy screws have feasibility for clinical application. © 2016 Wiley Periodicals, Inc.

“…Strontium has been considered an essential trace element for the human body. Strontium plays a special role in promoting osteoblast growth and inhibiting bone resorption [6]. Fluorine exists in the natural bone and tooth tissue as an essential element which can improve the crystallization and the mineralization of calcium phosphate for new bone formation [2].…”

Abstract. Hydroxyapatite (HAp) co-doped by magnesium (Mg), strontium (Sr), sodium (Na) and fluorine (F) was deposited on the 316L stainless steel (316L SS) substrate by electrodeposition method. The influences of scanning potential ranges, scanning times, scanning rates to form MgSrFNaHAp coating were investigated. The analytical results of FTIR, SEM, Xray, EDX, thickness and adhension of the obtained coating at scanning potential ranges of 0 ÷ -1.7 V/SCE; scaning times of 5, scanning rate of 5 mV/s showed that MgSrFNaHAp coatings were single phase crystals of HAp, exhibiting rod shape with the thickness of 8.9 µm and the adhesion strength reaching 8.38 MPa.
