Introduction: The treatment of intertrochanteric fractures in the elderly remains challenging for orthopedic surgeons, due to aging, comorbidities, and poor bone quality. The Heracles straight blade has proven a lower rate of cut-out and femoral head displacement in biomechanical studies; however, there are currently no published clinical studies using this nail.
Purpose: To analyze the clinical and radiological results of the Heracles nail with the straight cephalic Heracles blade as a device to treat osteoporotic intertrochanteric fractures of the proximal femur.
Methods: A total of 136 patients with trochanteric hip fractures were operated on by the same surgeon, using the Heracles nail with a straight cephalic blade. However, only 86 patients completed the 1-year follow-up both clinically and radiologically. According to the Association of Osteosynthesis classification, 38 patients (44.1%) had 31-A1, 36 patients (41.6%) had 31-A2, and 12 patients (14.1%) had 31-A3. Functional outcomes were assessed according to the Katz and Barthel scores, finding that 58% of patients recovered their original functional level, According to Barthel score, a mean loss of 11.8 points was found.
Results: The mean hospital stay was 8.22 days (mean preoperative stay of 2.71 days). The mean tip-apex distance was 15.2 mm. During the follow-up, 6 complications (6.96%) were detected: 4 cut-out, 1 cut-in, and 1 nail breakage. According to the Katz score, 58% of the patients recovered their previous functional status and 20.58% needed an additional walking aid. The mean loss in the Barthel score was 11.8 points.
Conclusion: The Heracles nail using a cephalic straight blade has proven to be a valid treatment of trochanteric fractures, due to the functional recovery of the patients and low level of complications.

Objectives: Transoral robotic surgery (TORS) for benign glottic conditions is scarcely represented in the literature. We aimed in this study to report on the technical feasibility of an explicitly transoral robotic approach for a patient with posterior glottic stenosis, and to highlight extant limitations in exposure and robotic instrumentation of the glottis.
Methods: Retrospective chart review of a single patient undergoing a TORS approach to maximize the posterior glottic aperture.

We improve the aerodynamic performance of a simplified vertical-axis wind turbine (VAWT) using a biomimetic flap, inspired by the movement of secondary feathers of a bird's wing at landing (Liebe 197954). The VAWT considered has three NACA0018 straight blades at the Reynolds number of80000based on the turbine diameter and free-stream velocity. The biomimetic flap is made of a rigid rectangular curved plate, and its streamwise length is 0.
