Removal of a bent intramedullary nail (IMN) is a rare but challenging orthopedic problem. Several removal techniques have been described up to date; however, there is no extensive review and no algorithm to manage these cases in current literature. The purpose of this paper is to present two cases that presented with bent IMN and provide an algorithm for management of this rare complication.

Motivation: Coiled coils are a widespread structural motif consisting of multiple α-helices that wind around a central axis to bury their hydrophobic core. While AlphaFold has emerged as an effective coiled-coil modeling tool, capable of accurately predicting changes in periodicity and core geometry along coiled-coil stalks, it is not without limitations, such as the generation of spuriously bent models and the inability to effectively model globally non-canonical-coiled coils. To overcome these limitations, we investigated whether dividing full-length sequences into fragments would result in better models.

Objective: A Leonis Mova (LM; SB Kawasumi, Kanagawa, Japan), one of the steerable microcatheters, has a remote-controlled flexible catheter tip manipulated with a dial in the hand grip, which enables operators to overcome complicated branching in endovascular surgeries. We report a case of a pituitary tumor in which the LM worked effectively as a distal access catheter (DAC) in tumor embolization.
Case Presentation: A female patient in her 70s complained of bitemporal hemianopsia, and an MRI revealed a pituitary tumor that appeared hypervascular.

Wearable electrocardiogram (ECG) devices are the mainstream technology in the diagnosis of various cardiovascular diseases, in which soft, flexible, permeable electrodes are the key link in human-machine interface to capture bioelectrical signals. Herein, we propose a self-template strategy to fabricate silver-coated fiber/silicone (AgCF-S) electrodes. With a simple dissolving-curing-redissolving process, the polyvinyl acetate shell around the AgCF core is in-situ removed to form a three-dimensional (3D) multi-channel structure.

Introduction: Infected gap non-union is a serious complication seen in cases of diaphyseal fracture of forearm bones. It carries high morbidity in the form of severe functional impairment and poses a challenge to treat due to the complex anatomical relationship and articulations involved. Though there are multiple treatment options available, there are no guidelines for its management.

Objective: Osteosynthesis in dislocated diametaphyseal forearm fractures is intended to restore anatomy and function. Antegrade intramedullary nailing in the radius is used to restore length, rotation, and axis within the age-specific correction limits. Sufficient stability ensures early functional postoperative treatment without load.
