“…According to the manufacturer's specifications, a 194mm long, 5.6mm thick, and 16mm wide metal and composite plate with 12 holes was modelled. Cortical and bicortical screws (diameter 4.5 mm) were modelled as solid bodies and positioned at fracture fixation, [21][22][23][24][25] as shown in Figure 1.…”

“…13,26 Figure 2, shows a fixation assembly with 225,719 elements and 82,365 nodes. Based on published literature, all material properties of metal plates and laminate stacking sequence and fiber orientation for composite plate were assigned, 21,27 and it was shown in Table 1. The distal portion of the femur was rigidly fixed and the tip of the stem was loaded at an angle of 11° adduction in the frontal plane with an axial load of 500, 700 (one legged stance, partial load bearing), and 1500 N (peak load).…”

“…In our previous study, three different types of composite bone plates were used and evaluated the behavior of the PF fixation in IPO condition for intact bone condition, this study is an extension of our research work. 21 In the present study, various types of bone plates are used in PF fixation for stronger and weaker bone to evaluate the stress concentrations in the plate at fracture sites are assessed first, followed by the axial and shear movements are examined in the fracture fragment sites. Finally, the stresses at the femur bone, bone cement, hip implant and screws are investigated in order to determine the most effective bone plate for osteoporotic (weaker) bone under various loading situations.…”

The major concern after total hip arthroplasty (THA) is the incidence of periprosthetic fracture in the weaker bone, which can lead to subsequent revision surgery. Achieving the suitable fixation without affecting the stability of the well-fixed prosthesis remains controversial. Most of the studies examined the behavior of the Periprosthetic Fracture (PF) fixation (Vancouver “B1” type) through computational and experimentation on healthy bone condition with metal plates. The aim of the present study is to analyze the influences of the metal and composite bone plate PF fixation on the axial and shear movement at the fracture site. The PF fixation constructs were modeled with medical graded stainless-steel plate (construct A), titanium plate (construct B) and carbon/epoxy composite bone plate (construct C) with 12 holes and a 4 mm fracture gap. Analysis was carried out for all the stages (stage 1—Normal bone, stage 2—THA, stage 3—Immediate Post-Operative (IPO), stage 4—Post-Operative (PO) and, stage 5—Healed Bone (HB)) under various loadings for intact and osteoporosis conditions. The results showed higher stress in cortical bone for stage 3, whereas in all the other stages lower stresses were experienced in the cortical and cancelous bone under peak load in construct C for osteoporosis model compared with other constructs. The present study suggested the construct C may be suitable for osteoporosis bone conditions.

Background Joint replacement is one of the options to retrieve the interosseous distal radioulnar joint (DRUJ) function. DRUJ prosthesis has recently been introduced clinically to treat DRUJ instability. This article analyzes the biomechanical behavior of the prosthesis during different loadings by the finite element method. Methods CT images of a healthy 33 years old man were used to construct the three-dimensional geometry of the forearm bone. Then two models, a healthy foreman (Model A) and a damaged model with an inserted interosseous prosthesis (Model B), were constructed to analyze and compare the foreman's biomechanical behavior under different loading conditions using the finite element method. Both models were examined during pronation and supination with 500, 1000, 2000, and 5000 N.mm values. Also, both models were subjected to volar and dorsal loads with values of 10, 30, and 50 N and traction force with 100, 150, and 200 N. Results Maximum and minimum principal stresses were evaluated for bones in all conditions, and von Mises stress was considered for the prosthesis and fixing screws. In supination, the maximum stress in Model A is significantly higher than the Model B. However, the maximum principal stress of both models is similar during volar and dorsal loading. In Model A, the maximum principal stress in traction is much smaller than in Model B. The absolute value of minimum principal stress in pronation and supination in Model B is higher than in Model A. The prostheses and screws are subjected to higher stresses during pronation than supination. Also, the amount of stress created in prostheses and screws during volar and dorsal loading is almost equal. In traction loading, screws are subjected to significantly high stresses. Conclusion Our study indicates that the interosseous DRUJ prosthesis can perform the foreman's normal daily activities. This prosthesis provides the ability similar to a normal hand. Level of evidence IV.

“…In the present study, we investigated the behavior of the composite bone plate in PO and HB conditions using the optimal configuration for developing the composite bone plate. 18 The previous study by the present authors 19 on IPO condition with transverse fracture is extended here to 6 weeks (PO) and 6 months (HB) stage. Composite plates made of carbon fiber/ epoxy, flax/epoxy, and fiberglass/epoxy were attached to the fractured bone with transverse fracture, and maximum stress distribution in the plate near to fracture gap and compressive stress in the bone growing region are evaluated.…”

Conventional stainless steel or titanium plates are used for bone fracture fixation to provide support at fracture location. Plates with high elastic modulus reduce the transfer of compressive load at the fracture location (due to stress shielding), causing failure. The objective of the study is to find for composite bone plates with different types of fibers and varied fiber orientations for post-operative (PO) and healed bone (HB) conditions which can reduce the stress shielding. Femur fracture fixation was constructed with 12 holes narrow type with metal and composite bone plates. The fracture gap was constructed with soft bone region for post-operative (PO) condition and harder bone for healed bone (HB). Composite bone plates with different configurations (fiber directions) and types (thickness and width) were analyzed to study the stress distribution and movement in the fracture location. The models were analyzed and the stresses in plate and callus, movement and strain in axial and shear direction in both metal and composite bone plates were studied. The metal and composite plates (carbon fiber/epoxy, fiberglass/epoxy, and flax/epoxy) used for most common Vancouver type B1 fracture to observe the biomechanical behavior of different models in PO and HB condition. The FE simulation on different configurations and types of composite plates provide in-depth idea about choosing the suitable composite bone plate. There are variations in behavior for varying types and configurations, but the performance of most of the plates are either better or similar to that of metal plate, except the plates with higher width.
