“…However, this ability can cause critical complications when they removed from human bone. When Ti alloys are used for bone xators such as bone screws and intramedullary nails, Ti alloys form new bone on them and sometimes assimilate with original bone (osseointegration) [6][7][8] . Therefore, bone may be re-fractured when the xators are retrieved after bone healing [9][10][11][12][13] .…”

“…Therefore, surface treatments that do not cause bone formation are necessary for the safe utilization of Ti alloy. However, most of surface treatment techniques studied in the eld of biomaterials have targeted bone formation around Ti alloy [6][7][8][15][16][17] . Surface treatment techniques to inhibit bone formation around Ti alloy have never been studied.…”

When titanium (Ti) alloys are used for bone xators after bone fracture, Ti alloys form new bone around themselves in human bone. This ability can cause re-fracture when the xators are retrieved after bone healing. Surface treatments that do not cause bone formation around Ti alloy are necessary. The purpose of this study was to clarify the inhibitory effect of zirconium (Zr) coating on bone bonding of Ti alloy in rat femur. Non-coated and Zr-coated Ti implants were inserted into the medullary canal of the right and left femur (randomized to side). Four weeks later, the femurs with the implants were removed. The shear strength of implant xation with the bone was measured by a pull-out test. The amount of the residual new bone adhered on the implants after the pull-out test was evaluated. Pull-out shear strength and the amount of bone elements around implant were lower in Zr-coated group than in non-coated group. Our study indicates that Zr coating inhibits bone bonding between Ti implant and bone in vivo. This technique may be useful to prevent re-fracture when Ti implants are removed from human bone after bone healing.

“…15 Bone ingrowth into pores causes interlocking of the surrounding bone tissue with the implant, and may result in improved in vivo biomechanical stability and higher resistance to fatigue loading. 27 A study by Götz et al 28 showed that initial bone ingrowth is preferentially directed toward the pores of the implant. Thus, an added advantage is that laser-textured implants with open pores may provide improved stability during early stages of osseointegration.…”

Implant failure due to poor integration of the implant with the surrounding biomaterial is a common problem in various orthopedic and orthodontic surgeries. Implant fixation mostly depends upon the implant surface topography. Micron to nanosize circular-shaped groove architecture with adequate surface roughness can enhance the mechanical interlock and osseointegration of an implant with the host tissue and solve its poor fixation problem. Such groove architecture can be created on a titanium (Ti) alloy implant by laser peening treatment. Laser peening produces deep, residual compressive stresses in the surfaces of metal parts, delivering increased fatigue life and damage tolerance. The scientific novelty of this study is the controlled deposition of circular-shaped rough spot groove using laser peening technique and understanding the effect of the treatment techniques for improving the implant surface properties. The hypothesis of this study was that implant surface grooves created by controlled laser peen treatment can improve the mechanical and biological responses of the implant with the adjoining biomaterial. The objective of this study was to measure how the controlled laser-peened groove architecture on Ti influences its osteoblast cell functions and bonding strength with bone cement. This study determined the surface roughness and morphology of the peen-treated Ti. In addition, this study compared the osteoblast cell functions (adhesion, proliferation, and differentiation) between control and peen-treated Ti samples. Finally, this study measured the fracture strength between each kind of Ti samples and bone cement under static loading. This study found that laser peen treatment on Ti significantly changed the surface architecture of the Ti, which led to enhanced osteoblast cell adhesion and differentiation on Ti implants and fracture strength of Ti–bone cement interfaces compared with values of untreated Ti samples. Therefore, the laser peen treatment method has the potential to improve the biomechanical functions of Ti implants.

“…It is known that, when the surface of a titanium implant is roughened, bone apposition onto the implant surface and bone-implant interfacial strength is increased [10]. This property seems not peculiar to titanium alloy [11], and it is possible that the roughened surface of the stainless steel nail accelerated osteoconduction on the nail surface. Unlike the surface of the metal implants for cementless arthroplasties, the surface of the metals for osteosynthesis would not have to be highly osteoconductive.…”

This is to report a case of femoral fracture caused by removal of a femoral intramedullary nail. The patient was a 28-year-old male. We performed intramedullary nailing for his femoral shaft fracture with an interlocking femoral nail made of stainless steel with fluted structure and roughened surface. The nail was removed 2 years and 5 months later, and fresh fracture lines were found in the postremoval radiograph. We suspected there existed problems with the structure of the intramedullary nail as well as late removal of the nail.
