Surgeons are at high risk of developing long-term Work-Related Musculoskeletal Disorders (WMSDs) due to awkward sustained postures. Passive spine-supporting exoskeletons are a potential intervention to improve posture and reduce fatigue. The NekSpine ® was evaluated by 21 surgeons (15 male) across two hospital sites within a quaternary academic hospital system. Each surgeon performed at least two comparable procedures, one with the exoskeleton and one without. Surgeons completed pre- and postoperative surveys assessing NASA-TLX workload, usability, body-part discomfort, overall fatigue, and workflow disruptions. Eighty-two cases were evaluated (43 exoskeleton cases). Compared with baseline cases, surgeons reported reduced neck and upper back discomfort and lower overall fatigue when using the exoskeleton. The NekSpine ® exoskeleton may reduce spinal discomfort and fatigue during surgery, supporting its potential as an ergonomic intervention for surgeons.

Robotic surgery offers advantages over traditional open, laparoscopic, and endoscopic approaches, including faster patient recovery and reduced surgeon fatigue. The da Vinci 5 (DV5), is the newest system in the most widely used family of surgical robots. This pilot study examined the usability of the DV5 compared with the da Vinci Xi (DV Xi) from the perspective of the surgical team. A consulting surgeon, trainees, Certified Surgical Assistants (CSAs), and Certified Surgical Technicians (CSTs) were recruited during colorectal surgery cases using the DV5 or DV Xi. Team members completed pre- and postoperative surveys assessing discomfort, workload, and usability. Objective postural data were collected from the consulting surgeon and trainee. Nine cases were evaluated (DV5 = 5). The DV5 improved neck posture for surgeons and trainees, with no workload differences for other team members. The DV5 significantly improved physical ergonomic usability for the surgeon at the console.

Ear, nose, and throat (ENT) surgeons often perform multiple daily procedures requiring sustained postures while wearing headlights or loupes, increasing the risk of work-related musculoskeletal disorders (WMSDs). This in situ case study aimed to (1) evaluate ENT surgeon workload and (2) introduce ergonomic interventions through workflow changes, education, and personal protective equipment. Three trained ergonomists observed the intraoperative workflow of three ENT surgeons at a tertiary academic hospital, identifying awkward postures. Surgeons received education on surgical microbreaks and OR-Stretch before trialing passive exoskeletons. Exoskeleton effectiveness was evaluated using interviews and surveys. Workflow interventions improved neck posture. One surgeon reported reduced body-part discomfort but increased subjective workload when using the exoskeleton, while interviews identified aesthetic concerns. This exploratory case study identified workflow issues and introduced ergonomic interventions. Although one surgeon reported reduced discomfort with an exoskeleton, larger studies are needed to establish quantitative trends.

Hospital practitioners have a high prevalence of work-related musculoskeletal disorders due to manual patient transfers. Reducing patient transfers can improve safety for staff and patients, especially those with unstable spines. A study at our academic hospital with the Safe TrAnsfer Tray prototype (STAT Tray V1) found transfers could be reduced to the two unavoidable transfers at the beginning and end of care. Surveys from 37 practitioners identified clinical challenges. User feedback informed design requirements for STAT Tray V2. Candidate materials were tested for MRI and CT compatibility, and pressure mapping evaluated padding combinations to reduce pressure-related injuries. STAT Tray V2 was designed for MRI and CT compatibility, current lift systems, and patients ranging from the 5th percentile female to the 95th percentile male while reducing pressure injury risk. Following manufacturing, usability testing will evaluate performance in the Emergency Department, imaging, operating suite, and ICU.
