As one of the treatment options, we intend to offer a simple, safe, and robust internal fixation method for avulsion fractures of the calcaneal tuberosity as one of the treatment options. Key words: 180-degree annular internal fixation, avulsion fractures of the calcaneal tuberosity, new device.
During cataract surgery, we treated 15 eyes in 15 patients who were reported to have almost 180° zonular dialysis; The needle was used to stitch the equatorial portion of the capsule from the inside to the outside and then pull the suture thread under the scleral flap. The IOL was inserted into the bag after the thread was tied to a preceding loop of IOL.
Bats have wings made of a durable membrane and a joinedted skeletal framework that allow them to perform intricate flight maneuvers such as rapid tight turns. Since the U-turn, the bat was seen to reduce its flight speed and gain about 20 cm of altitude. Centrial force was created by tilting the lift force vector laterally into banking, which was later used to create centricity. The flap amplitude of the right wing increased relative to the left wing during the inception and persistence throughout the U-turn. In addition, the right wing moved more closely to the body's centerline at the time of the downstroke and the upstroke in comparison to the left wing. The bat's flight path began to change quickly as the bat negotiated the turn's apex. Once the bat turned and the bank angle increased, the bat's flight course began to change rapidly. The minimum radius of curvature of the bat was 5. 5 cm during this phase of the turn. As the turn began, the bat accelerated and expended stored potential energy by declining, extending. During the six wingbeat cycle, the bat averaged total power expenditure by the bat during the U-turn maneuver was 0. 51 W, which was around 40% more than the power expenditure estimated for a nominally straight flight by the same bat. A broader range of maneuvering flights characterizing the similarities and differences among flights can be investigated by future work on bat maneuverability.
