“…However, SS 316L contains 13%-15% nickel which is potentially toxic and may also cause allergic reactions in patients with metal sensitivity. 11 New nickel free stainless steel has been developed mainly to address this issue, though it is not yet widely clinically adopted. 11 It is important to note that the stainless steel still does not have optimum corrosion resistance.…”

“…11 New nickel free stainless steel has been developed mainly to address this issue, though it is not yet widely clinically adopted. 11 It is important to note that the stainless steel still does not have optimum corrosion resistance. To improve the anti-corrosion performance, titanium and its alloys (Young's modulus of 110 GPa) started being used for internal fracture fixation after they became commercially available in the 1950s.…”

Metal and its alloys have been predominantly used in fracture fixation for centuries, but new materials such as composites and polymers have begun to see clinical use for fracture fixation during the past couple of decades. Along with the emerging of new materials, tribological issues, especially debris, have become a growing concern for fracture fixation plates. This article for the first time systematically reviews the most recent biomechanical research, with a focus on experimental testing, of those plates within ScienceDirect and PubMed databases. Based on the search criteria, a total of 5449 papers were retrieved, which were then further filtered to exclude nonrelevant, duplicate or non-accessible full article papers. In the end, a total of 83 papers were reviewed. In experimental testing plates, screws and simulated bones or cadaver bones are employed to build a fixation construct in order to test the strength and stability of different plate and screw configurations. The test set-up conditions and conclusions are well documented and summarised here, including fracture gap size, types of bones deployed, as well as the applied load, test speed and test ending criteria. However, research on long term plate usage was very limited. It is also discovered that there is very limited experimental research around the tribological behaviour particularly on the debris’ generation, collection and characterisation. In addition, there is no identified standard studying debris of fracture fixation plate. Therefore, the authors suggested the generation of a suite of tribological testing standards on fracture fixation plate and screws in the aim to answer key questions around the debris from fracture fixation plate of new materials or new design and ultimately to provide an insight on how to reduce the risks of debris-related osteolysis, inflammation and aseptic loosening.

“…Traditional medical metals for bone implants mainly include stainless steel, titanium alloy, Co-Cr alloy, etc. [7][8][9]. However, recent researches find that there are some disadvantages in these implants: The toxic ions, Ni and Cr ions released from stainless steel, as well as Al released from titanium alloy, which will cause irreversible damage if absorbed excessively by the human body [10][11][12]; The elastic modulus of these bone implants is too much higher than that of natural bone, which can not avoid stress shielding effect [13,14]; These implants can not degrade completely by themselves, and they need to be taken out again after bone healing [15].…”

Implant therapy after osteosarcoma surgery is a major clinical challenge currently, especially the requirements for mechanical properties, degradability of the implants, and their inhibition of residual tumor cells. Biodegradable magnesium (Mg) alloy as medical bone implant material has full advantages and huge potential development space. Wherein, Mg–lithium (Li) based alloy, as an ultra-light alloy, has good properties for implants under certain conditions, and both Mg and Li have inhibitory effects on tumor cells. Therefore, Mg–Li alloy is expected to be applied in bone implant materials for mechanical supporting and inhibiting tumor cells simultaneously. In this contribution, the Mg–xLi–Zinc (Zn) series alloys (x = 3 wt%, 6 wt%, 9 wt%) were prepared to study the influence of different elements and contents on the structure and properties of the alloy, and the biosafety of the alloy was also evaluated. Our data showed that the yield strength, tensile strength, and elongation of as-cast Mg–xLi–Zn alloy were higher than those of as-cast Mg–Zn alloy; Mg–xLi–Zn alloy can kill osteosarcoma cells (MG-63) in a concentration-dependent manner, wherein Mg–3Li–Zn alloy (x = 3 wt%) and Mg–6Li–Zn alloy (x = 6 wt%) promoted the proliferation of osteoblasts (MC3T3) at a certain concentration of Li. In summary, our study demonstrated that the Mg–6Li–Zn alloy could be potentially applied as a material of orthopedic implant for its excellent multi-functions.

“…Rabbit femora have been used in mechanical simulations of human femora for decades 11,12 because of the similarity in their shape (including anterior and lateral bowing of the femora) and biomechanical properties. Finite-element analysis (FEA) is also widely used as an effective method for studying femoral biomechanics 13 .…”

Background:Femoral pin-site fracture is one of the most serious complications of navigation-assisted total knee arthroplasty (TKA). Its occurrence is associated with the loss of biomechanical strength caused by intraoperative femoral drilling. This study aimed to investigate the drilling location as a risk factor for pin-site fracture.Methods:A biomechanical analysis using rabbit femora was performed to determine the effects of drilling eccentricity and height. Torsional, 3-point bending, and axial compression tests were performed to evaluate biomechanical parameters, including failure strength, failure displacement, and stiffness. Fracture type and the presence of comminution were noted and analyzed. Finite-element analysis (FEA) was utilized to assess the stress distribution and deformation. The cumulative sum (CUSUM) method was applied to define the safe range for drilling eccentricity.Results:Drilling operations were accurately implemented. Biomechanical tests confirmed that severely eccentric drilling significantly reduced the biomechanical strength of the femur, especially in torsion. FEA results provided evidence of threatening stress concentration in severely eccentric drilling. The overall safe range of eccentricity relative to the center of the femur was found to be between 50% of the radius in the anterolateral direction and 70% of the radius in the posteromedial direction.Conclusions:Severely eccentric drilling significantly increased the risk of femoral pin-site fracture, especially under torsional stress. Femoral drilling should be performed in the safe zone that was identified.
