Manual retraction, a task performed to expose the surgical site, poses a high risk for musculoskeletal disorders that affect the hands, arms, shoulders, neck, and back. In recent years, minimally invasive and laparoscopic procedures have led to the development of multifunctional instruments and retractors capable of performing these functions that, in many cases, has eliminated the need for manual retraction. During surgical procedures that are not performed endoscopically, the use of self-retaining retractors enables the assistant to handle tissue and use exposure techniques that do not require prolonged manual retraction. Ergonomic Tool #5: Tissue Retraction in the Perioperative Setting provides an algorithm for perioperative care providers to determine when and under what circumstances manual retraction of tissue is safe and when the use of a self-retaining retractor should be considered.

Unlabelled: Congenital myotonic dystrophy type 1 (DM1) is a rare entity that can pose a diagnostic challenge, especially if other processes such as prematurity coexist.
Objective: to describe the typical presentation of congenital DM1 and thus increase diagnostic suspicion.
Clinical Case: A 29-week preterm female newborn who required non-invasive mechanical ventilation until 41 weeks postmenstrual age; she presented with apnea requiring manual ventilation with a self-inflating bag and cardiac massage.

Objective: To evaluate and compare the skeletal and dental treatment effects of Class II malocclusion cases using skeletally anchored Forsus (miniscrew-anchored FRD or miniplate-anchored FRD), with conventional Forsus FRD.
Materials And Methods: Unrestricted electronic search of six databases and additional manual searches were performed up to July 2023. Randomized controlled trials having one treatment arm with skeletal anchored Forsus FRD in treatment of Class II malocclusion and another matched treatment group treated with conventional Forsus FRD were included in this review.

In percutaneous interventions, needles are used to reach target locations inside the body. However, when the needle is pushed through the tissue, forces arise at the needle tip and along the needle body, making the needle prone to buckling. Recently, needles that prevent buckling inspired by the ovipositor of female parasitic wasps have been developed.

Background: Tear size and shape are known to prognosticate the efficacy of surgical rotator cuff (RC) repair however, current manual measurements on magnetic resonance images (MRI), exhibit high interobserver variabilities and exclude three-dimensional (3D) morphological information. This study aimed to develop algorithms for automatic 3D analyses of posterosuperior full-thickness RC tear to enable efficient and precise tear evaluation and 3D tear visualization.
Methods: - A deep-learning network for automatic segmentation of the tear region in coronal and sagittal multicenter MRI was trained with manually segmented (consensus of 3 experts) pd- and T2 weighted MRI of shoulders with full-thickness posterosuperior tears (n=200).

Objective: Most robots currently used in neurosurgery aid surgeons in placing spinal hardware and guiding electrodes and biopsy probes toward brain targets. These robots are inflexible, cannot turn corners, and exert excessive force when dissecting and retracting brain tissue, limiting their applicability in cranial base surgery. In this study, the authors present a novel soft-pouch robot prototype driven by compressed air and capable of gentle tissue manipulation.
