“…These simulations can effectively and efficiently evaluate a lot of variables such as surgical techniques and implant types used for various pathologies to optimize design, screening, prediction, and cost‐effectively in the treatment in orthopedics . Previously, several studies investigated the biomechanics of AC joint and human shoulder complex by using FEA …”

Background: Although many techniques are used to treat the acromioclavicular (AC) joint dislocations, minimal invasive or arthroscopic coracoclavicular ligament reconstructions became popular recently. In this study, authors compared the biomechanical results of double versus triple button reconstruction techniques.Methods: Three-dimensional solid modeling of the shoulder girdle was carried out using virtual finite element modeling. AC joint dislocation was applied to the reference model, and these models were repaired by double and triple button techniques, respectively. Maximum equivalent stresses on buttons and sutures as well as displacements and reaction forces on AC joint were evaluated. Results: Triple button model was more stable during flexion and abduction when compared with double button technique. Conclusion: Mimicking conoid ligament has a crucial mission more particularly against resistance during frontal plane actions, but the absence of the trapezoid ligament causes increasing the posterior displacement of the distal clavicle during the flexion of GH joint.

“…Works on computer-based simulation and investigation of bone osteosynthesis plates made of magnesium alloys are not abundant (Shirurkara, Tamboli, Jagtap, Dondapati, & Davidson, 2017). More frequently, bone fixations plates produced of the traditional materials (titanium alloys and stainless steel) are investigated (Lee et al, 2016;Shih, Huang, Pan, Lee, & Su, 2015;Hung, Su. Lu, & Lee, 2017;Cronskar, Rasmussen, & Tinnsten, 2015).…”

Biodegradable materials are used in two key sectors of orthopaedics – to fabricate bone fixators and scaffolds for bone tissue regeneration. In case of osteosynthesis, fixators made from biodegradable materials disappear from the body after a certain time. So, a necessity of a one more operation for their removal is excluded. In the present study, the acromioclavicular joint osteosynthesis plates made of magnesium alloy (WE43), titanium alloy (Ti-6Al-7Nb) and stainless steel (316L) are compared utilizing the finite element analysis. The research showed that stresses in the magnesium alloy plate were lower, compared to the titanium alloy plate or the stainless steel plate. However, the tensile strength of magnesium is over 2 times lower, as compared to stainless steel and 5 times lower, than titanium alloys. Magnesium alloy is not suitable for manufacturing plates with low thickness (2 and 2.5 mm), because the stresses generated in them exceed the yield strength of the material.

“…Nonetheless, different implants and methods of internal fixation as well as the mechanical effects of clavicle fixation are also explored . In addition, some scholars also indicated that using a longer clavicle hook plate decreased and mitigated the force that clavicle hook plates exert on the acromion and the stress value in the clavicle .…”

Clinical implantation of clavicle hook plates is often used as a treatment for acromioclavicular joint dislocation. However, it is not uncommon to find patients that have developed acromion osteolysis or had peri-implant fracture after hook plate fixation. With the aim of preventing complications or fixation failure caused by implantation of inappropriate clavicle hook plates, the present study investigated the biomechanics of clavicle hook plates made of different materials and with different hook depths in treating acromioclavicular joint dislocation, using finite element analysis (FEA). This study established four parts using computer models: the clavicle, acromion, clavicle hook plate, and screws, and these established models were used for FEA. Moreover, implantations of clavicle hook plates made of different materials (stainless steel and titanium alloy) and with different depths (12, 15, and 18 mm) in patients with acromioclavicular joint dislocation were simulated in the biomechanical analysis. The results indicate that deeper implantation of the clavicle hook plate reduces stress on the clavicle, and also reduces the force applied to the acromion by the clavicle hook plate. Even though a clavicle hook plate made of titanium alloy (a material with a lower Young's modulus) reduces the force applied to the acromion by the clavicle hook plate, slightly higher stress on the clavicle may occur. The results obtained in this study provide a better reference for orthopedic surgeons in choosing different clavicle hook plates for surgery.
