Old pelvis fractures are among the most challenging to treat because of their complex anatomy, difficult-to-access surgical sites, and relatively low incidence such cases. Proper evaluation planning necessary achieve pelvic ring symmetry stable fixation fracture. The goal this study was assess use three-dimensional (3D) printing techniques for management old fractures.First, 16 dried human cadaveric pelvises were used confirm anatomical accuracy 3D models printed based on radiographic data....
Abstract Introduction Pelvic fracture is a severe high-energy injury with the highest disability and mortality of all fractures. Traditional open surgery associated extensive soft tissue damages many complications. Minimally invasive potentially mitigates risks surgical procedures becoming new standard for pelvic treatment. The accurate reduction has been recognized as cornerstone minimally fracture. At present, closed in fractures limited by current sub-optimal 2D intra-operative imaging...
To evaluate the bi-planar robot navigation system for insertion of cannulated screws in femoral neck fractures.Between January 2016 and December 2016, 60 patients with fractures were separately treated using percutaneous assisted by (robot group) conventional freehand surgery (freehand group). The fluoroscopy time, number drilling attempts, operation time recorded during operations; dispersion parallelism on posteroanterior lateral images measured after operations. Patients followed up 12-24...
Displaced pelvic fracture is among the most complicated fractures in traumatic orthopedics, with high mortality and morbidity. Reduction considered a complex procedure as well key part surgical treatment. However, few robotic techniques have been employed reduction of fracture, despite rapid advancement technologies. Recently, we designed robot surgery system specialized autonomous displaced applied it true patient for first time. In this paper, report its successful clinical debut fracture....
To explore effectiveness of TiRobot-assisted screw implantation in the treatment coracoid process fractures scapula. A retrospective analysis was conducted on clinical data from 24 patients with scapula admitted between September 2019 and January 2024 met selection criteria. Among them, 12 underwent (robot group) manual (control during internal fixation. There no significant difference ( P>0.05) baseline such as gender, age, body mass index, disease duration, cause injury, fracture...
To address the performance degradation of traditional underwater target localization algorithms in high-speed motion scenarios, this paper proposes a vertically moving method based on interference feature matching using single hydrophone. Due to overlapping fringes time–frequency domain, first employs two-dimensional homomorphic filter separate different types while removing line-spectrum interference. Then, theoretical period database is constructed, and performed achieve target. Simulation...
Introduction Accurate segmentation of pelvic fractures from computed tomography (CT) is crucial for trauma diagnosis and image-guided reduction surgery. The traditional manual slice-by-slice by surgeons time-consuming, experience-dependent, error-prone. complex anatomy the bone, diversity fracture types, variability in surface appearances pose significant challenges to automated solutions. Methods We propose an automatic method based on deep learning, which effectively isolates hipbone...
Accurate orthopedic fracture reduction planning is essential for ensuring successful postoperative recovery and improving patient outcomes. However, current automatic methods are challenged by the complex irregular geometries scarcity of annotated training data. To address these challenges, we propose a novel approach that integrates learning-based shape restoration simulation. A transformer-based model developed, which utilizes patch-to-patch translation recursive fragment registration to...
The segmentation of pelvic fracture fragments in CT and X-ray images is crucial for trauma diagnosis, surgical planning, intraoperative guidance. However, accurately efficiently delineating the bone remains a significant challenge due to complex anatomy imaging limitations. PENGWIN challenge, organized as MICCAI 2024 satellite event, aimed advance automated by benchmarking state-of-the-art algorithms on these tasks. A diverse dataset 150 scans was collected from multiple clinical centers,...
To assess the efficiency, safety, and accuracy of S2 (IS) screw fixation using a robot-assisted method compared with freehand method.This is retrospective clinical study. We analyzed patients treated IS for unstable pelvic fractures from January 2016 to 2019 in our institution. Sixty-three (17 men 46 women) aged between 21 55 years (with an average age 39.22 ± 9.28) were included this According Tile classification, there 26 (41.3%) type B 37 (58.7%) C fractures. All divided into (RA) group...
Spine-related diseases have high morbidity and cause a huge burden of social cost. Spine imaging is an essential tool for noninvasively visualizing assessing spinal pathology. Segmenting vertebrae in computed tomography (CT) images the basis quantitative medical image analysis clinical diagnosis surgery planning spine diseases. Current publicly available annotated datasets on are small size. Due to lack large-scale dataset, mainstream deep learning-based segmentation methods, which...
Pelvic fracture is known to be one of the most difficult injuries. The first and foremost step for pelvic reduction structural recovery. However, due lack data on healthy pelvis before fracture, result entirely based experience surgeons. This study proposed a novel method automatic planning symmetry (pelvic reduction, PSR), which could provide template surgery as well related surgical robot. A symmetrical area (ROI) without fragments was extracted from fractured through multiple SP...
Pelvic acetabular fracture is a common kind of fracture, mostly caused by high energy injuries. It associated with mortality and disability rates. The aim surgical treatment pelvic fractures to restore the symmetry stability ring structure anatomical acetabular. Open reduction internal fixation often used for such fractures, but open surgery in cases serious injury, more bleeding, risk infection. With development minimally invasive technology concept bone channel structure, percutaneous lag...
Displaced fragility fractures of the pelvis (FFP) pose significant challenges in orthopaedic trauma, owing to patient comorbidities, deteriorating bone quality, and surgical complexities. Despite technological advancements, no robotic methods have been documented for displaced FFP management. To address this, we introduced an advanced robot-assisted fracture reduction system, comprising a tracking device, path planning software, arms. This study evaluated fifteen consecutive patients with...
Pelvic fracture is among the most complicated fractures in traumatic orthopedics, with high mortality and morbidity rates. The main difficulty associated reduction surgery significant muscle resistance. It then becomes necessary to decrease force against this strong resistance, for improving surgical safety. Here, we propose a novel traction method decreasing during pelvic reduction, investigate performance of elastic on using experimental tests simulation-based analyses. From results,...
