Reduction of Work-Related Musculoskeletal Disorders in Plastic Surgeons by Introduction of a Posture Training Device.

BACKGROUND: Plastic surgeons have an increased risk for the development of musculoskeletal disorders because of frequent poor ergonomics of the operating room. This study characterizes selected plastic surgery procedures, with an attempt to identify high-risk procedures and procedural components as well as the impact of biofeedback on surgical ergonomics. METHODS: A commercially available posture training device was used to initially record neck and spine positioning and later to send biofeedback to prompt surgeons to correct posture. Device data were correlated with in-person observations to characterize factors associated with more time spent in the slouched/nonneutral cervical and thoracic spine posture. RESULTS: The proportion of time spent in the upright position during surgery was significantly different among male and female participants, level of training, participant height, in the sitting versus nonsitting positioning (P < 0.001), with loupes use, and if there was more than an 8-inch height difference between 2 participants (mean, 0.70 ± 0.285). Using the device intervention, all participants spent a larger proportion of operating time upright. Half of these improvements in posture were statistically significant. While in feedback mode, participants experienced shorter and more frequent periods of slouching/nonneutral posture. When comparing the same participant performing the same procedure with and without device biofeedback, 72.2% of participants spent more time in the upright/neutral posture during the surgery when the device was sending feedback. CONCLUSIONS: Biofeedback devices used in the operating room can lead to improved surgical posture, which may translate to reduction of workplace injuries, and overall physician health. This study found that a commercially available posture training device and sitting stools in the operating room could significantly improve physician cervical and thoracic spine posture.

Tissue Expander-Assisted Component Separation for Pediatric Abdominal Wall Reconstruction.

BACKGROUND: Tissue expander-assisted component separation can be used to increase the amount of skin, muscle, and fascial components available for repair of congenital abdominal wall defects via a staged approach without the need for flap reconstruction. We present the largest case series to date using a tissue expander-assisted component separation technique for treatment of congenital abdominal wall defects in a pediatric patient population. METHODS: A retrospective chart review of 9 patients with large congenital abdominal wall defects not initially amenable to primary repair between 2009 and 2020 was performed. Patients first underwent placement of tissue expanders, followed by removal once they had reached a sufficient expander volume. Component separation, with and without mesh placement, was performed to achieve abdominal wall closure. RESULTS: The average age of patients at primary repair was 3.2 years (SD ±1.7 years). Eight patients (88.8%) had congenital omphalocele, and 1 patient (11.1%) had gastroschisis; none were amenable to primary repair. The average size of the defects before closure was 87.6 cm2 (SD = 33.6 cm2). Eighteen tissue expanders were placed in 9 patients, 72.2% of which were placed in the plane between the external and internal oblique muscles. Patients were seen in clinic an average of 6.8 times (SD, ±3.3 visits) for volume expansion into the tissue expander, receiving an average of 32.0 mL in each per visit. An average of 4.3 months (SD, ±1.8 months) elapsed between placement and removal of the expanders. At the time of tissue expander removal and abdominal wall closure, the defects ranged from 30 to 132 cm2 (mean, 54 cm2). All defects were successfully repaired using a component separation and bilateral fasciocutaneous flap advancement. Two patients (18.2%) experienced infection of the surgical site and seroma, both of which required debridement. One patient (9.1%) experienced partial thickness skin necrosis that was managed nonsurgically. The overall complication rate was 36.4%. CONCLUSIONS: Omphalocele and gastroschisis can produce abdominal wall defects that are not amenable to primary repair. Staged reconstruction using tissue expander-assisted component separation is a safe and effective method of obtaining adequate local soft tissue to achieve primary closure.
