Background The operating room is a high-risk environment where proper patient positioning is crucial for minimizing injury and ensuring optimal access to surgical sites. This process requires effective collaboration among surgical team members, particularly operating room nurses who play a vital role in patient safety. Despite advancements in technology, challenges such as pressure injuries persist, with a significant incidence rate. Video-based training (VBT) emerges as a promising educational tool, enhancing knowledge retention and fostering a learner-centered approach. This study aims to evaluate the impact of VBT on adherence to surgical positioning standards, highlighting its potential to improve safety protocols in the operating room. Methods In this clinical trial, 62 qualified operating room nurses (50 women, 12 men, average age: 28.90 ± 3.75 years) were randomly divided into control and intervention group ( n  = 31 in each group). The control group only received positioning recommendations, but in the intervention group, in addition to the recommendations, video-based surgical positioning training was performed for 1 month, at least 3 times a week. The performance of nurses in both groups was evaluated through a researcher-made checklist at baseline and post-intervention. Results Based on findings, there was no significant difference between the two groups in compliance with surgical positioning standards at baseline ( p  = 0.07). However, after the intervention, compliance scores significantly improved in the VBT group compared to the control group ( p  < 0.001). The VBT group showed a mean improvement of 62.12 points, while the control group improved by 10.77 points ( p  < 0.001). Conclusions This preliminary study demonstrated a notable improvement in compliance with surgical positioning standards among operating room nurses following VBT intervention. Despite the promising results, the small sample size and preliminary nature of the research necessitate further studies to confirm these findings and assess long-term outcomes. These initial insights highlight the potential of innovative training methods in enhancing surgical practices.

With the help of surgical navigation system, doctors can operate on patients more intuitively and accurately. The positioning accuracy and real-time performance of surgical instruments are very important to the whole system. In this paper, we analyze and design the detection algorithm of surgical instrument location mark, and estimate the posture of surgical instrument. In addition, we optimized the pose by remapping. Finally, the algorithm of location mark detection proposed in this paper and the posture analysis data of surgical instruments are verified and analyzed through experiments. The final result shows a high accuracy.

ABSTRACT Aim To establish a set of scientific and practical surgical positioning quality evaluation indicators for the operating room in China. Design A mixed‐methods study with a quantitative component. Methods Literature review and expert group discussions were conducted to identify the potential surgical positioning quality evaluation indicators for the operating room. Then, Delphi surveys were used to collect opinions from experts in the field of surgical positioning. The consistency of the consultation results formed the basis on which we conducted the next rounds of consultation. Based on the importance given to each indicator by the consulted experts in the previous round, we determined the weight coefficient of each indicator with the analytic hierarchy process. Results The questionnaire recovery rates of the two rounds of correspondence were 82.61% and 73.91%, and the average authoritative coefficients were 0.94 and 0.92. The Kendall W values ranged from 0.155 to 0.270 (p < 0.001). The weight coefficients for the first‐level, second‐level and third‐level indicators were 0.157–0.576, 0.046–0.292 and 0.014–0.210, respectively. Consensus was reached on 3 primary indicators, 7 secondary indicators and 19 tertiary indicators. No Patient or Public Contribution This study did not involve patients or the public; data were derived from expert consultations and literature analysis.

PurposeHyperextension-distraction type injury of the thoracolumbar spine is an unstable fracture pattern that generally necessitates surgical stabilization by posterior instrumentation. Care must be taken when positioning these patients from supine to prone due to the unstable nature of their injury. The study objectives were (1) to describe a novel modification of the Jackson table turn technique, which may be safer and more effective than the conventional log-roll method and traditional Jackson table technique for positioning patients with hyperextension-distraction injuries of the thoracolumbar spine from supine to prone in the operating room and (2) to present two cases in which this technique was successfully performed.MethodsTwo patients were carefully positioned from supine to prone by our modification of the Jackson table turn technique, which utilizes a Wilson frame sandwiched between two flat-top Jackson frames. Case 1: a 65-year-old female presented status-post motor vehicle collision with a T9–T10 extension-distraction injury, requiring T7–T12 posterior spinal instrumented fusion (PSIF). Case 2: a 72-year-old female presented status-post motor vehicle collision with a T9–T10 extension-distraction injury and an unstable L1 burst fracture, requiring T7–L2 PSIF.ResultsBoth patients remained hemodynamically stable and neurologically intact throughout positioning and postoperatively.ConclusionsThis technique is safe and effective for positioning patients with hyperextension-distraction type injuries of the thoracolumbar spine from supine to prone in the operating room and may be superior to conventional methods.Graphical abstractThese slides can be retrieved under Electronic Supplementary Material.

PurposePercutaneous retrograde fixation of posterior column acetabular fractures is becoming a commonly practiced technique. Prone positioning provides reliably reproducible intraoperative fluoroscopic images necessary for precise preparation of the osseous fixation corridor necessary for accurate and safe implant placement. Additionally, the prone position facilitates an open posterior approach if an open reduction is necessary. The purpose of this study was to analyze the radiographic and clinical outcomes of retrograde posterior column fixation utilizing the prone position.MethodsFrom 2017 to 2020, 41 patients were included in the retrospective study. Clinical outcomes were collected for a minimum of 6 months. Implant placement was assessed on post-operative pelvic computed tomography (CT) scans and fracture union was assessed on routine follow-up radiographs.ResultsAll (100%) cases achieved union by 4 months, with an average time to union of 3.2 months. Every post-operative CT scan demonstrated screw placement contained throughout the posterior column with no intrusion into the hip joint or sciatic notch. Clinically, one patient reported pain with sitting. No patients required additional surgical intervention.ConclusionProne positioning is a versatile and effective approach for retrograde percutaneous fixation of posterior column acetabular fractures. This study is the first to report clinical outcomes utilizing this technique and contributes to a growing body of the literature supporting the value and safety of percutaneous fixation of acetabular fractures appropriate for this fixation strategy.

Pressure ulcers are soft‐tissue damage associated with tissue exposure to sustained deformations and stress concentrations. In patients who are proned for ventilation or surgery, such damage may occur in the superficial chest tissues that are compressed between the rib cage and the support surface. Prophylactic dressings have been previously proven as generally effective for pressure ulcer prevention. In this study, our goal was to develop a novel computational modelling framework to investigate the biomechanical efficacy of a dressing with a soft cellulose fluff core in protecting proned surgical patients from chest pressure ulcers occurring on the operating table, due to body fixation by the Relton‐Hall frame. We compared the levels of mechanical compressive stresses developing in the soft chest tissues, above the sternum and ribs, due to the trunk weight, whilst the body is supported by the Relton‐Hall frame pads, with versus without the prophylactically applied bilateral dressings. The protective efficacy index for the extremely high stresses, above the 95th‐percentile, were 40.5%, 25.6% and 24.2% for skin, adipose and muscle, respectively, indicating that the dressings dispersed elevated soft‐tissue stresses. The current results provide additional support for using soft cellulose fluff core dressings for pressure ulcer prophylaxis, including during surgery.

Background Anesthesia for spinal muscular atrophy (SMA) patients undergoing spinal deformity surgery is challenging. We report an unusual case of an SMA girl who developed severe intraoperative hypoxemia and hypotension during posterior spinal fusion related with surgical positioning. Case presentation A 13-yr-old girl diagnosed with SMA type 2, severe kyphoscoliosis and thoracic deformity was scheduled for elective posterior spinal fusion. She developed severe hypoxemia and profound hypotension intraoperatively in the prone position with surgical table tilted 45° to the right. Though transesophageal echocardiography (TEE) could not be performed due to limited mouth opening, her preoperative computed tomography revealed a severely distorted thoracic cavity with much reduced volume of the right side. A reasonable explanation was when the surgeons performed surgical procedure with the tilted surgical table, the pressure was directly put on the shortest diameter of the significantly deformed thoracic cavity, causing severe compression of the pulmonary artery, resulting in both hypoxemia and hypotension. The patient stabilized when the surgical table was tilted back and successfully went through the surgery in the leveled prone position. Conclusions Spinal fusion surgery is beneficial for SMA patients in preventing scoliosis progression and improving ventilation. However, severe scoliosis and thoracic deformities put them at risk of both hemodynamic and respiratory instability during surgical positioning. When advanced monitoring like TEE is not practical intraoperatively, preoperative imaging may help with differential diagnosis, and guide the surgical positioning to minimize mechanical compression of the thoracic cavity, thereby helping the patient complete the surgery safely.

Peripheral nerve injuries are largely preventable injuries that can result from incorrect patient positioning during surgery. Patients who are diabetic, are extremely thin or obese, use tobacco, or undergo surgery lasting more than four hours are at increased risk for developing these injuries. When peripheral nerve injuries occur, patients may experience numbness, burning, or tingling and may have difficulty getting out of bed, walking, gripping objects, or raising their arms. These symptoms can interrupt activities of daily living and impede recovery. Signs and symptoms of peripheral nerve injury may appear within 24 to 48 hours of surgery or may take as long as a week to appear. Careful attention to body alignment and proper padding of bony prominences when positioning patients for surgery is necessary to prevent peripheral nerve injury. The use of a preoperative assessment tool to identify at-risk patients, collaboration between physical therapy and OR staff members regarding patient positioning, and neurophysiological monitoring can help prevent peripheral nerve injuries.

Cobb angles and apical vertebral rotations (AVR) are two of the main scoliosis deformity parameters which spinal instrumentation and fusion techniques aim to reduce. Despite this importance, current surgical positioning techniques do not allow the reduction of these parameters. Two new surgical frame accessory prototypes have been developed: (1) a lateral leg displacer (LLD) allows lateral bending of a patient’s legs up to 75° in either direction and (2) a pelvic torsion device (PTD) which allows transverse plane twisting of a patient’s pelvis at 30° in either direction while raising the thoracic cushion, opposite to the raised side of the pelvis, by 5 cm. The objective of this study was to evaluate the ability of the LLD and PTD to reduce Cobb angles and AVR. Experimental testing was performed pre-operatively on 12 surgical scoliosis patients prone on an experimental surgical frame. Postero-anterior radiographs of their spines were taken in the neutral prone position on a surgical frame, and then again for 6 with their legs bent towards the convexity of their lowest structural curve, 4 with their pelvis raised on the convex side of their lowest structural curve and one each in opposite LLD and PTD intended use. Use of the LLD allowed for an average supplementary reduction of 16° (39%) for Cobb angle and 9° (33%) for AVR in the lowest structural curve. Use of the PTD allowed for an average supplementary reduction of 9° (19%) for Cobb angle and 17° (48%) for AVR in the lowest structural curve. Both devices were most efficient on thoraco-lumbar/lumbar curves. Opposite of intended use resulted in an increase in both Cobb angle and AVR. The LLD and PTD provide interesting novel methods to reduce Cobb angles and AVR through surgical positioning which can be used to facilitate instrumentation procedures by offering an improved intra-operative geometry of the spine.
