RESUMO
Context: Multiple high-energy injuries and complex, pelvic acetabular fractures are challenging injuries. With the help of a 1:1-sized solid model of the human body, 3D printing technology can achieve personalized customization of the surgical methods. Objective: The study intended to compare the clinical efficacy of three-dimensional (3D)-printing-assisted and traditional, open reduction and internal fixation in the treatment of complex pelvic acetabular fractures. Design: The research team conducted a randomized controlled trial and also provided a case study for one participant in the intervention group. Setting: The study took place at the First Affiliated Hospital of Yangtze University in Jingzhou, Hubei, China. Participants: Participants were 48 patients with complex pelvic acetabular fractures at the hospital between January and December 2018. Interventions: The research team randomly divided participants into two groups, with 24 participants in each group: (1) the 3D group, which received treatment in which surgeons used 3D-printing technology for preoperative planning, and (2) the routine group, which received routine treatment. Outcome Measures: The research team measured: (1) perioperative conditions, including operation time, intraoperative blood loss, and postoperative drainage volume; (2) fracture reduction quality; and (3) a case study of a postoperative imaging examination. Results: The 3D group's operation time (P = .001), intraoperative blood loss (P = .001), and postoperative drainage volume (P = .001) were significantly lower than those of routine group. According to the Matta imaging standards, the fracture reduction quality for the 3D group was excellent for 16 participants (66.66%), good for four participants (16.67%), and fair for four participants (16.67%), with the total quality rate at 83.33% for 20 participants. For the routine group, the quality was excellent for eight participants (33.33%), good for four participants (16.67%), and fair for 12 participants (50.00%), with the excellent and good rates at 50.00% for 12 participants. The 3D group's fracture reduction quality was significantly higher than that of the routine group (P < .05). Conclusions: 3D printing technology in the treatment of complex pelvic acetabular fractures can be helpful for surgeons to understand a fracture's characteristics; formulate an optimized and accurate, personalized surgical plan before an operation; improve the reduction's safety and accuracy; shorten the operation time; reduce the occurrence of postoperative complications; and improve clinical efficacy.
RESUMO
BACKGROUND: Open distal tibial fractures pose significant challenges regarding treatment options and patient outcomes. This retrospective single-centre study aimed to compare the stability, clinical outcomes, complications, and financial implications of two surgical interventions, namely the external locking plate and the combined frame external fixator, to manage open distal tibial fractures. METHODS: Forty-four patients with distal open tibial (metaphyseal extraarticular) fractures treated between 2020 and 2022 were selected and formed into two main groups, Group A and Group B. Group A (19 patients) are patients that underwent treatment using the external locking plate technique, while Group B (25 patients) received the combined frame external fixator approach. Age, gender, inpatient stay, re-operation rates, complications, functional recovery (measured by the Johner-Wrush score), pain ratings (measured by the Visual Analogue Scale [VAS]), and cost analyses were evaluated for each group. Statistical analyses using SPSS were conducted to compare the outcomes between the two groups. RESULTS: The research found significant variations in clinical outcomes, complications, and cost consequences between Group A and Group B. Group A had fewer hospitalisation periods (23.687.74) than Group B (33.5619.47). Re-operation rates were also considerably lower in Group A (26.3%) than in Group B (48%), owing to a greater prevalence of pin-tract infections and subsequent pin loosening in the combination frame external fixator group. The estimated cost of both techniques was recorded and analysed with the locking average of 26,619.69 ± 9,602.352 and the combined frame average of 39,095.64 ± 20,070.077. CONCLUSION: This study suggests that although the two approaches effectively manage open distal tibia fractures, the locking compression plate approach (Group A) has an advantage in treating open distal tibia fractures. Shorter hospitalisation times, reduced re-operation rates, and fewer complications will benefit patients, healthcare systems, and budget allocation. Group A's functional recovery results demonstrate the locking plate technique's ability to improve recovery and patient quality of life. According to the cost analysis, the locking plate technique's economic viability and cost-effectiveness may optimise healthcare resources for open distal tibia fractures. These findings might improve patient outcomes and inform evidence-based orthopaedic surgery.
