“…TBW has been generally accepted as the standard treatment for Mayo type IIA fracture of the olecranon [3,9]. Although this technique showed excellent outcomes in both biomechanical and clinical studies [11][12][13][14], high rates of complications and re-operation procedures have been reported [6-8].…”

Material parameters(Table 1) (including modulus of elasticity, Poisson ratio, density of wire, and patella bone), contact parameters between the olecranon and wire, the boundary condition, and the tension load on the olecranon were de ned based on a previous study [9].…”

Background:Tension band wiring (TBW) is common surgical intervention for olecranon fractures. However, high rate of complications such as loss of reduction, skin irritation, and migration of the K-wires were reported up to 80%. We have developed a new cannulated screw with holes on the tail, which called Ding’s screw. The goal of this study was to evaluate the stability of Ding’s screw and tension band wiring (DSTBW) for treatment of olecranon fractures by using a finite element analysis. Method: We conducted a finite element model by using two fixation methods: Ding’s screw and tension band wiring (DSTBW) and K-wire tension band wiring (TBW), were simulated to fix the olecranon fractures. The stress distribution, opening angle, twisting angle, and pullout strength of K-wires or screws were analyzed and compared. Results: The highest von Mises stress of fixation happened in 90°elbow movement in both groups. The value was 241.2 MPa at scews in DSTBW, and was 405.0 MPa at K-wires in TBW. Opening angle: 0.730°,0.741° at 45° and 0.679°, 0.693° at 90° elbow flexion for TBW and DSTBW, respectively. Twisting angle: 0.146°,0.180° at 45° flexion and 0.111°, 0.134° at 90° flexion for TBW and DSTBW, respectively. There was much higher pullout strength of DSTBW when compared to TBW. The maximum pullout strength was 2179.1N for screws in DSTBW, and it was 263.6N for K-wires in TBW. Conclusion: The technique of DSTBW can provide stable fixation to olecranon fractures, and reduce the risk of failure and migration of medical apparatus and instruments.

“…The relevant material properties of the finite element model of olecranon fracture were set up, and a three-dimensional finite element model similar to the actual model in terms of material parameters and mechanical behavior was established. According to the actual data of clinical internal fixation device, two kinds of internal fixation structures involved in this study were constructed by Solidworks software, and the material properties of olecranon cortical bone, olecranon cancellous bone, Kirschner wire, steel wire and titanium alloy (plate and screw) were set ( Civan et al, 2021 ; Kim et al, 2021 ). The specific parameters are shown in Table 2 , the three-dimensional model and internal fixation model of olecranon bone are assembled in SolidWorks software.…”

“…The three-dimensional finite element models of two groups of internal fixation were fixed in the olecranon fracture model. Within 1 s, 120 N force was applied to the 90° direction of the surface of the olecranon fracture block, and 200 N force was applied to the 45° direction ( Civan et al, 2021 ). The magnitude and direction of the loading force are shown in Figure 2 .…”

Objective: This study aimed to introduce a new surgical method for the fixation of olecranon fractures, and to compare the biomechanical stability and clinical efficacy of Kirschner wire tension band and anchor loop plate (ALP) in the treatment of olecranon fractures.Methods: A finite element model was established to analyze the mechanical properties of Kirschner wire tension and anchor loop plate fixation for olecranon fracture. The clinical data of 53 patients with olecranon fractures admitted to our hospital from March 2016 to October 2021 were retrospectively analyzed. Among them, 22 cases were fixed with an anchor loop plate (ALP group), and 31 patients were fixed with the Kirschner wire tension band technique. By reviewing the medical records and follow-up results, the final elbow mobility, secondary surgery, postoperative complications and elbow function recovery Mayo score and DASH score were compared between the two groups.Results: The biomechanical analysis of the finite element model showed that under the load of 120 N, the maximum displacement of the Kirschner wire group was 1.09 times that of the ALP group, the maximum stress of the Kirschner wire group was 1.33 times that of the ALP group, and the maximum stress of the olecranon proximal bone of the Kirschner wire group was 2.17 times that of the ALP group. Under the load of 200 N, the maximum displacement of the Kirschner wire group was 1.19 times that of the ALP group. The overall maximum stress of the Kirschner wire group was 1.59 times that of the ALP group, and the maximum stress of the proximal olecranon bone of the Kirschner wire group was 1.99 times that of the ALP group. The average follow-up time of the Kirschner wire and anchor loop plate groups was similar (p > 0.05). The average age of the two groups was identical (p > 0.05). The final elbow mobility in the anchor loop plate group was significantly greater than in the Kirschner wire group (p < 0.05). The Mayo score of the anchor loop plate group was substantially higher than that of the Kirschner wire group at 3 and 12 months after operation (p < 0.05), and the DASH score was significantly lower than that of the Kirschner wire group (p < 0.05). Postoperative complications in the two groups: 1 case (4.5%) in the anchor loop plate group had difficulties with internal fixation stimulation, and no infection occurred; in the Kirschner wire group, 5 cases (16.1%) had complications of internal fixation stimulation, and 1 patient (3.2%) had an infection.Conclusion: The model of olecranon fracture fixed by anchor loop plate and Kirschner wire tension technique was tested under 120 and 200 N tension, and no damage was found, indicating that the newly designed anchor loop plate was safe in mechanical structure. The biomechanical stability of the anchor plate technique is more stable, so it is not easy to have postoperative complications such as fracture block cutting and internal fixation failure. And the secondary operation rate and elbow function have better results. This technique is an effective method for the treatment of olecranon fractures.

Background Tension band wiring (TBW) is a common surgical intervention for olecranon fractures. However, high rate of complications such as loss of reduction, skin irritation, and migration of the K-wires were reported up to 80%. Ding’s screw tension band wiring (DSTBW) is a new TBW technique that has shown positive results in the treatment of other fracture types. The objective of this study was to evaluate the stability of DSTBW in the treatment of olecranon fractures by finite element analysis. Method We used Ding’s screw tension band fixation (DSTBW) and K-wire tension band fixation (TBW) to establish a finite element model to simulate and fix olecranon fractures. The stress distribution, opening angle, twisting angle, and pullout strength of K-wires or screws were analyzed and compared. Results The maximum von Mises stress was observed on the internal fixation for 90° elbow motion in both groups. The von Mises value of the screw in DSTBW was 241.2 MPa, and the von Mises value of k-wire in TBW was 405.0 MPa. Opening angle: TBW was 0.730° and DSTBW was 0.741° at 45° flexion; TBW was 0.679° and DSTBW was 0.693° at 90° flexion. Twisting angle: TBW was 0.146° and DSTBW was 0.180° at 45° flexion; TBW was 0.111° and DSTBW was 0.134° at 90° flexion. The pullout strength of DSTBW was significantly higher than that of TBW. Maximum pullout strength of Ding’s screw was 2179.1 N, maximum pullout strength of K-wire was 263.6 N. Conclusion DSTBW technology provides stable fixation for olecranon fractures, reducing the risk of internal fixation migration and failure.
