In this cadaveric study of anterior plating of the distal radius, we aimed to determine the interobserver agreement and diagnostic performance for detecting dorsally protruding screws using the dorsal tangential radiographic view before and after specific training. Without prior instruction, 13 observers interpreted the dorsal tangential view of cadaveric specimens, in which anterior radial plates were placed. After seeing a training video on the dorsal tangential view, they repeated the task. Though we found that accuracy and interobserver agreement was lower than described in some other clinical series, training led to statistically significant improvements of (1) the interobserver agreement on the decision to exchange screws, (2) the self-confidence of the surgeon in obtaining adequate views, and (3) the number of fluoroscopic images required to obtain these views. After training, the number of protruding screws missed was reduced by 36%, but 7% of dorsally protruding screws was still missed.

Histological Study of Skin Structures From Selected Body Areas in the Varanus komodoensis.

The skin of the Komodo dragon (Varanus komodoensis) is covered by a form of armour formed mainly of scales, which often co-occur with osteoderms. Scales are keratinized, non-mineralized structures in the uppermost layer of the epidermis that are in contact with each other to form a system in which individual scales are isolated from each other by a softer skin fold zone. In the Varanus, the surface of the scales is flat and smooth (thoracic limb, abdomen, and tail areas), domed and smooth (head area) or domed with conical ornamentation (dorsal surface, pelvic limb-dorsal surface areas).

Background: Minimally invasive technique for surgical management of colorectal metastasis is becoming the standard practice in the United States. Paracaval colorectal metastasis is a technically challenging tumor to resect due to its location. Abutment of the inferior vena cava (IVC) often requires advanced technique for vascular dissection and potential need for partial venous resection.

Background: The skyline or dorsal tangential view (DTV) and the carpal shoot-through (CST) have been developed to enhance the intraoperative examination of the distal radius's dorsal cortex during open reduction and internal fixation with volar plates. This study aimed to assess the lateral view (LV), DTV, and CST's effectiveness in showcasing screws that penetrate the dorsal cortex.
Methods: Eighty patients, comprised of 42 women and 38 men with an average age of 53 years, underwent volar locking plate fixation for displaced distal radius fractures.

Complex behaviors arise from neural circuits that assemble from diverse cell types. Sleep is a conserved behavior essential for survival, yet little is known about how the nervous system generates neuron types of a sleep-wake circuit. Here, we focus on the specification of Drosophila 23E10-labeled dorsal fan-shaped body (dFB) long-field tangential input neurons that project to the dorsal layers of the fan-shaped body neuropil in the central complex.

Introduction: Due to its ability to provide stable fixation and permit early mobilization, volar plating has become the recommended technique for the surgical stabilization of distal radius fractures. The extensor pollicis longus (EPL) tendon may be injured or ruptured as a result of undetected screw penetration or drill plunging. During surgery, it is critical to detect any potential screw penetration so that it can be corrected.
