EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:1457-1463. [PMID: 38240824 DOI: 10.1007/s00590-023-03821-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 12/20/2023] [Indexed: 04/02/2024]
Abstract
INTRODUCTION The use of a robotic system for the placement of pedicle screws in spine surgeries is well documented in the literature. However, there is only a single report in the United States describing the use of a robotic system to place two screws in osseous fixation pathways (OFPs) commonly used in the treatment of pelvic and acetabular fractures in a simulated bone model. The purpose of this study was to demonstrate the use of a robotic system to place screws in multiple, clinically relevant OFPs in a cadaveric model and to quantitatively measure accuracy of screw placement relative to the preoperative plan. METHODS A single cadaveric specimen was obtained for the purpose of this study. All surrounding soft tissues were left intact. Screws were placed in OFPs, namely iliosacral (IS), trans-sacral (TS), Lateral Compression-II (LC-II), antegrade anterior column (AC) and antegrade posterior column (PC) of the right hemipelvis using standard, fluoroscopically assisted percutaneous or mini-open technique. Following the placement of screws into the right hemipelvis using standard techniques, screws were planned and placed in the same OFPs of the contralateral hemipelvis using the commercially available ExcelsiusGPS® robotic system (Globus Medical Inc., Audubon, PA). After robotic-assisted screw placement, a post-procedure CT scan was obtained to evaluate actual screw placement against the pre-procedure plan. A custom-made image analysis program was devised to measure screw tip/tail offset and angular offset on axial and sagittal planes. RESULTS For different OFPs, the mean tip offset, tail offset and angular offsets were 1.6 ± 0.9 mm (Range 0.0-3.6 mm), 1.4 ± 0.4 mm (Range 0.3-2.5 mm) and 1.1 ± 0.4° (Range 0.5-2.1), respectively. CONCLUSION In this feasibility study, surgeons were able to place screws into the clinically relevant fracture pathways of the pelvis using ExcelsiusGPS® for robotic-assisted surgery. The measured accuracy was encouraging; however, further investigation is needed to demonstrate that robotic-assisted surgery can be used to successfully place the screws in the bony corridors of the pelvis to treat traumatic pelvic injuries.

Abstract
Key Clinical Message It may be possible to extend the use of the robotic arm to pelvic and acetabular surgery leading to safe, repeatable screw placement, and less radiation exposure for patients, surgeons and OR staff. Abstract In this case, a novel, robotic-assisted technique was used to place a sacroiliac screw in a patient with unstable injuries of the pelvic ring. Intraoperative and postoperative fluoroscopic, radiographic, and CT imaging demonstrated a safely positioned 6.5 mm cannulated screw without unplanned cortical violation or impingement on neurovascular structures. To our knowledge, this is the first such reported case using a robot widely available in the Americas or Europe.

Abstract
Robotic-assisted total knee arthroplasty (RA-TKA) has demonstrated improved alignment and outcome scores when compared with manual total knee arthroplasty (M-TKA); however, few studies compare differences in the same patient. This study is a retrospective review that assesses clinical outcomes of 36 patients who underwent a primary RA-TKA and had undergone a prior contralateral M-TKA. All surgeries were performed by a single surgeon at the same institution. Patients were assessed for differences in hospital length of stay, improvement in pre- versus postoperative range of motion, Knee Injury and Osteoarthritis Outcome Score (KOOS), and Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores. Student's t-test and Fisher's exact test were utilized to detect significant differences. Patient demographics showed a mean age of 64.5, 24 females (67%), and mean body mass index of 35.1 ± 5.7. The average follow-up time was 2.9 years for M-TKA and 1.3 years for RA-TKA. Hospital length of stay was decreased by 5.5 hours for RA-TKA (p = 0.03). Total postoperative WOMAC score was not statistically different between RA-TKA and M-TKA (p = 0.061); however, pain and stiffness components were statistically improved in RA-TKA (p = 0.041 and p = 0.007), respectively. KOOS was higher in RA-TKA, which approached statistical significance (p = 0.005). Pre- versus postoperative knee flexion improved significantly in both cohorts. There was a significant difference in pre- versus postoperative range of motion at 3, 6, and 12 months follow-up after RA-TKA in comparison to M-TKA (p < 0.05). There were no postoperative complications. Patients who underwent RA-TKA demonstrated early improvement at 1-year follow-up in pain, stiffness, and knee flexion when compared with their prior contralateral M-TKA. There was a significant decrease in postoperative length of stay by 5.5 hours in the RA-TKA group. Limitations include a small sample size and differences in follow-up times between RA-TKA and M-TKA.

Abstract
Approximately 20% of the patients are dissatisfied with their total knee arthroplasty (TKA). Computer technology has been introduced for TKA to provide real time intraoperative information on limb alignment and exact flexion/extension gap measurements. The purpose of this study was to determine if patient satisfaction could be improved with the use of robotic-assisted (RA) technology following primary TKA. A total of 120 consecutive patients undergoing RA-TKA with real time intraoperative alignment and gap balancing information were compared with a prospective cohort of 103 consecutive patients undergoing TKA with manual jig-based instruments during the same time period. There were no differences between groups with age, gender, baseline Knee Society Score (KSS) knee and function scores, follow-up, and ASA scores. TKAs were performed using same technique, implant design, anesthesia, and postoperative treatment protocols. Patient satisfaction survey using KSS and Likert scoring system were obtained at 1-year follow-up. Likert scoring system demonstrated 94% of the patients in the RA group were either very satisfied or satisfied versus 82% in the manual instruments TKA group (p = 0.005). RA-TKA group had better average scores of all five satisfaction questions although not significant. RA-TKA group had a better average overall satisfaction score of 7.1 versus 6.6 in the manual instrument group, p = 0.03. KSS function scores were significantly better at 6 weeks and 1 year postoperatively (p = 0.02, 0.005), and KSS knee scores were significantly better at 1 year postoperatively (p = 0.046). There are multiple reasons for patient dissatisfaction following primary TKA. Using intraoperative computer technology with RA surgery for patients undergoing a primary TKA, a significant improvement in patient satisfaction was demonstrated compared with TKA using conventional manual jig-based instruments. RA surgery provides several advantages in TKA including real time information in millimeters to help obtain balanced gaps, accurate bone cuts, reduced soft tissue injury, and achieve the target alignment which may lead to improved patient satisfaction.

Percutaneous-assisted vs mini-laparoscopic hysterectomy: comparison of ultra-minimally invasive approaches. Updates Surg 2020; 73:2347-2354. [PMID: 32996053 DOI: 10.1007/s13304-020-00893-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Accepted: 09/21/2020] [Indexed: 01/28/2023]
Abstract
To assess the feasibility and the safety of the ultra-minimally invasive (U-MIS) approaches in gynecology, we compared our experience in percutaneous assisted hysterectomy (PSS-H) with a series of 3 mm mini-laparoscopy hysterectomy (m-LPS-H). 126 patients affected by benign and malignant gynecological conditions were considered eligible for minimally invasive hysterectomy: 80 patients received PSS approach and 46 m-LPS approach. For both groups, we evaluated intra and perioperative outcomes, post-operative pain and cosmetic outcomes. The baseline characteristics were comparable between the two study groups. As well, no differences were reported in the clinical indications for hysterectomy, principally fibroids/adenomyosis, endometrial hyperplasia and early stage endometrial cancer. The median operative time was 88.5 (40-190) minutes for PSS-H group and 95.0 (42-231) minutes in m-LPS-H group (p = 0.131). No differences were detected in median estimated blood loss (p = 0.104) as well, in the uterine manipulator usage (p = 0.127) between the two different surgical approaches. Only 1 (2.2%) conversion to standard laparoscopy occurred in m-LPS-H group (p = 0.691). One intra-operative complication was recorded 1 (1.3%) in the PSS-H group (p = 0.367). The post-operative early complication was recorded in five cases of PSS-H group (p = 0.158), none for m-LPS-H procedures. The results in post-operative pain detection was statistically significant after 4 h in favor of m-LPS-H group (p = 0.001). After 30 days no differences in cosmetic satisfaction were detected between the two groups (p = 0.206). PSS-H and m-LPS-H are two valid U-MIS alternatives for benign gynecological conditions and low/intermediate risk endometrial cancer.

Abstract
AIM The purpose of this study was to report on 626 cases of successful robotic single-site (RSS) surgeries to address various types of gynecologic disease and to evaluate the outcomes and learning curve inherent to RSS surgery in the gynecology field. METHODS A total of 626 cases of RSS surgeries were performed by 3 gynecologic surgeons at Ewha Womans University Medical Center, Robot Surgery Center from November 2014 to January 2018 were collected retrospectively. All of the patients' charts were reviewed, and the clinical characteristics and surgical variables were analyzed. RESULTS Among the total of 626 cases, there were 220 cases of RSS myomectomy (RSSM), 182 cases of RSS hysterectomy (RSSH), 195 of RSS adnexectomy, 24 of RSS sacrocolpopexy (RSS SCP) and 5 were classified as other RSS surgeries. The patient's mean age was 38.98 ± 10.07 years. There was 3.99 ± 2.15 min of mean docking time and 117.78 ± 51.18 min of mean operating time. The surgical variables were analyzed annually. The total operating time was seen to decrease significantly according to each period. The docking time declined significantly and gradually after 1 year. We also analyzed each of the surgical types by time. The operating time of RSSH, RSSM, RSS adnexectomy and RSS SCP fell over time. The tendency found was for operating time to decline sharply following the first 10 cases. When we analyzed the data at annual intervals, the operating time was most significantly less and stable following the first year. There were a few intraoperative or perioperative complications in 16 cases (2.6%). CONCLUSION Robotic single-site surgery is a feasible and safe procedure for treating various kinds of gynecologic diseases. The learning curve was approximately 10 cases of RSS surgery in gynecologic disease, having a greater amount of experience at performing RSS surgery was revealed to be key to achieving better surgical outcomes.
