Wire breakage during percutaneous coronary intervention is a rare event. It occurs especially when treating complex lesions, and it should be prevented with careful planning of each procedural step. We reported a case in which wire breakage occurred when treating the left anterior descending (LAD)/first diagonal bifurcation with the T-stenting technique. After careful evaluation of all the available retrieval techniques and failure of the balloon-catheter trapping, the twin-twisting wires technique (TTWT) was applied. This technique allows the retrieval of a foreign body thanks to its entrapment in the spiral made by two twisting wires. At the first attempt, the broken wire was only withdrawn and not retrieved, while the two twisting wires went broken. The second attempt was performed using stronger wires as twisting wires. The two recently broken fragments were successfully retrieved together with a long proximal remnant of the initially broken wire, which distal tip was further withdrawn. The broken wire was successfully retrieved with the third attempt, together with the previously implanted LAD stent that was accidentally entrapped in the twist. This is the first report of TTWT implementation for the retrieval of a broken wire from a two-stent bifurcation, both proximal and distal wire remnants and a total of three broken wires. The improvements we made to the technique, tips and tricks, caveats, and suggestions for successful wire retrieval and avoidance of the complications that we experienced are described in detail.

The adoption of pultruded glass fibre-reinforced polymer (pGFRP) composites as a substitute for traditional wooden cross-arms in high transmission towers represents a relatively novel approach. These materials were selected for their high strength-to-weight ratio and lightweight properties. Despite various studies focusing on structures improvement, there still have a significant gap in understanding the deformation characteristics of full-scale cross-arms under actual operational loads.

Background: The fracture of an endodontic instrument within the root canal system can occur during root canal therapy, complicating thorough cleaning and shaping. Consequently, managing the broken fragment becomes crucial.
Methods: Eighty Nickel-titanium (NiTi) #20 K-files (Mani, Tochigi, Japan) were cut 8 mm from the tip, fixed into a corkboard, and classified into five groups (n = 14 each).

Introduction: Intramedullary femoral nails (IMFNs) need to be removed for subsequent joint replacement, refracture, nonunion, or infection. The tools used to extract newer IMFNs may not be suited for removal of older implants, especially if broken. The purpose of this study was to describe a novel technique in femoral nail extraction when primary measures fail and a report on 6 cases where it was used.

Background: Sternoclavicular joint dislocation (SJD) is rare, and joint instability after dislocation easily leads to deformity, pain, and limitations in performing activities, often requiring surgical treatment. Currently, there is no ideal internal fixation method for SJD.
Case Presentation: We report the case of a 38-year-old female patient with anterior dislocation of the right sternoclavicular joint (SJ) caused by a car accident who underwent open reduction and internal fixation using the double plate technique combined with the cable technique.

Introduction: In this case report, we would like to discuss about a 51-year-old gentleman, who had underwent patella tension band wiring for transverse patella fracture 3 years ago and presented with a painful knee with broken cerclage wire with a fragment migrating into the joint.
Case Report: The aim of the study was to highlight the importance of higher imaging (Computed tomography) in deciding whether the retrieval of the fragment can be attempted through a minimally invasive arthroscopic technique.
Result: CT of the knee joint with 3D reconstruction was done and it showed the broken migrated fragment to be intra-articular and intracapsular.
