Purpose: This study aimed to validate the use of ProAnalyst (Xcitex Inc.), a program for professional motion analysts to assess the performance of surgical interns while performing the peg transfer task in a simulator box for safe practice in real minimally invasive surgery.
Methods: A correlation study was conducted in a multidisciplinary skills simulation lab at the Faculty of Medicine, Jordan University of Science and Technology from October 2019 to February 2020. Forty-one interns (i.e., novices and intermediates) were recruited, and an expert surgeon participated as a reference benchmark. Videos of participants’ performance were analyzed using ProAnalyst and the Global Operative Assessment of Laparoscopic Skills (GOALS). The two sets of results were analyzed to identify correlations.
Results: The motion analysis scores from Proanalyst were correlated with those from GOALS for efficiency (r=+0.38, P<0.05), autonomy (r=+0.63, P<0.01), depth perception (r=+0.43, P<0.05), dexterity (r=+0.71, P<0.001), and operation flow (r=+0.88, P<0.001). Both assessment methods differentiated the participants’ performance based on their experience level.
Conclusion: The motion analysis scoring method using Proanalyst provides an objective, time-efficient, and reproducible assessment of interns’ performance, with results comparable to those obtained using GOALS. It may require initial training and set-up; however, it eliminates the need for expert surgeon judgment.

Head motion is a major source of image artifacts in head computed tomography (CT), degrading the image quality and impacting diagnosis. Image-domain-based motion correction is practical for routine use since it doesn't rely on hard-to-obtain CT projection data. However, existing convolutional neural network (CNN)-based methods tend to over-smooth images, particularly in cases of moderate to severe 3D motion artifacts.

Background: This study aimed to investigate the clinical effects of bone fusion distal to the phalangeal epiphyseal plate in treating asymmetrical type III thumb polydactyly, focusing on growth and scar healing.
Methods: In patients with asymmetrical type III thumb syndactyly, the proximal phalanx of the accessory finger, distal epiphyseal plate, and some soft tissue were excised to create a pedicled tissue flap. This flap, containing part of the nail and bone distal to the epiphyseal plate, was subsequently attached to the distal segment of the main finger.

Background: Open reduction and internal fixation or primary arthrodesis are considered gold standards for treating Lisfranc injuries. However, several drawbacks are associated with these procedures, such as joint motion loss and potential cartilage damage. More recently, the suture button emerged as an alternative treatment for ligamentous Lisfranc injuries, which can be used either alone or in combination with traditional techniques, with the potential to mitigate some of these potential disadvantages.

This study develops a finite element solution to analyze the vibration response of multi-layer shape memory alloy (SMA) composite beams. Using Euler-Bernoulli beam motion equations with tension-compression asymmetry, based on Poorasadion's model, the Newmark method and Newton-Raphson technique are employed. Validating the model against ABAQUS/Standard results for a homogeneous SMA beam shows good agreement.

Asphalt pavement has become a vital component of modern highway construction due to its high wear resistance, short construction period, economic viability, and excellent skid resistance. However, increasing traffic volume has heightened the structural performance requirements of asphalt pavement, especially during compaction. The compaction degree of asphalt mixtures has emerged as a key indicator for assessing construction quality.
