Abstract Background This present study is aimed to retrospectively assess the efficacy of three-dimensional (3D) printing assisted osteotomy guide plate in accurate osteotomy of adolescent cubitus varus deformity. Material and methods Twenty-five patients (15 males and 10 females) with the cubitus varus deformity from June 2014 to December 2017 were included in this study and were enrolled into the conventional group (n = 11) and 3D printing group (n = 14) according to the different surgical approaches. The operation time, intraoperative blood loss, osteotomy degrees, osteotomy end union time, and postoperative complications between the two groups were observed and recorded. Results Compared with the conventional group, the 3D printing group has the advantages of shorter operation time, less intraoperative blood loss, higher rate of excellent correction, and higher rate of the parents’ excellent satisfaction with appearance after deformity correction (P < 0.001, P < 0.001, P = 0.019, P = 0.023). Nevertheless, no significant difference was presented in postoperative carrying angle of the deformed side and total complication rate between the two groups (P = 0.626, P = 0.371). Conclusions The operation assisted by 3D printing osteotomy guide plate to correct the adolescent cubitus varus deformity is feasible and effective, which might be an optional approach to promote the accurate osteotomy and optimize the efficacy.

Talipes Equinovarus

Abstract Objectives: This current research is aimed to assess clinical efficacy and prognosis of three-dimensional (3D) printing assisted osteotomy guide plate in precise osteotomy of adult talipes equinovarus (ATE). Materials and Methods: We included a total of 27 patients of ATE malformation (including 12 males and 15 females) from January 2014 to June 2018 in current research. The patients were divided into the routine group (n=12) and 3D printing group (n=15) based on different operative methods. The parameters, including the operative time, intraoperative blood loss, complications, time to obtain bony fusion, functional outcomes based on American Orthopedic Foot and Ankle Society (AOFAS) and International Congenital Clubfoot Study group (ICFSG) scoring systems between the two groups were observed and recorded regularly. Results: The 3D printing group exhibits superiorities in shorter operative time, less intraoperative blood loss, higher rate of excellent and good outcomes presented by ICFSG score at last follow-up (P< 0.001, P< 0.001, P =0.019) than the routine group. However, there was no significant difference exhibited in AOFAS score at last follow-up and total rate of complications between the two groups (P=0.136, P =0.291). Conclusions: Operation assisted by 3D printing osteotomy guide plates for correcting the ATE malformation is novel and feasible, which might be an effective method to polish up the precise osteotomy of ATE malformation and enhance the clinical efficacy.

Objective To assess the outcomes of traditional three-dimensional (3D) printing technology (TPT) versus mirror 3D printing technology (MTT) in treating isolated acetabular fractures (IAFs). Methods Consecutive patients with an IAF treated by either TPT or MTT at our tertiary medical centre from 2012 to 2018 were retrospectively reviewed. Follow-up was performed 1, 3, 6, and 12 months postoperatively and annually thereafter. The primary outcome was the Harris hip score (HHS), and the secondary outcomes were major intraoperative variables and key orthopaedic complications. Results One hundred fourteen eligible patients (114 hips) with an IAF (TPT, n = 56; MTT, n = 58) were evaluated. The median follow-up was 25 months (range, 21–28 months). At the last follow-up, the mean HHS was 82.46 ±14.70 for TPT and 86.30 ± 13.26 for MTT with a statistically significant difference. Significant differences were also detected in the major intraoperative variables (operation time, intraoperative blood loss, number of fluoroscopic screenings, and anatomical reduction number) and the major orthopaedic complications (loosening, implant failure, and heterotopic ossification). Conclusion Compared with TPT, MTT tends to produce accurate IAF reduction and may result in better intraoperative variables and a lower rate of major orthopaedic complications.

Abstract Purpose The Nice knots have been widely used in orthopedic surgeries to fix torn soft tissue and fracture in recent years. The study aims to investigate the clinical efficacy and prognosis of intraoperative and postoperative Nice Knots-assisted reduction in the treatment of displaced comminuted clavicle fracture. Methods From Jan 2014 to Dec 2019, 75 patients diagnosed with unilateral closed displaced comminuted clavicle fracture were treated with open reduction and internal fixation (ORIF) in this study. Nice knot group (the NK group) included 38 patients and the other 37 patients were in the traditional group (the TK group). The time of operation and the amount of bleeding during operation were recorded. Post-operative clinical outcomes and radiographic results were recorded and compared between these two groups. The Visual Analogue Scale (VAS), Neer score, Rating Scale of the American Shoulder and Elbow Surgeons, Constant-Murley score and complications such as infection, nonunion, implant loosening, fragment displacement and hardware pain were observed in the two groups. Results In the comparison between the two groups, there was no significant difference in age, sex, the cause of displaced clavicle fracture, and other basic information between the two groups. The operation time, intraoperative fluoroscopy time, and intraoperative blood loss were significantly reduced in the NK group (P < 0.01). There were 2 cases of plate fracture in the TK group. The follow-up results showed that there was no significant difference in VAS, Neer score, ASES, and Constant-Murley scores between the two groups. Conclusion The use of Nice knot, in comminuted and displaced clavicle fractures can reduce intraoperative blood loss, shorten operation time, facilitate intraoperative reduction, and achieve satisfactory postoperative clinical results. This study demonstrates that Nice knot is a simple, safe, practical and effective auxiliary reduction method.

Abstract We aim to evaluate the surgical outcome of laparoendoscopic two-site myomectomy (LETS-M). The medical records of 204 women receiving LETS-M in a tertiary referral center, including 183 surgeries performed by the experienced surgeon and 21 surgeries performed by 3 well-supervised trainees were retrospectively reviewed. The age of the participants was 39.3±6.4 years. The mean diameter of the largest myoma was 8.5±2.2 cm. The mean weight of the myomas was 281.1±183.1 g. The operation time was 97.6±40.2 min, and the intraoperative blood loss was 99.3±115.2 mL. There were 3 (1%) cases of excessive blood loss (more than 500 mL) and 2 (1%) of postoperative hematoma. The only significant difference between the experienced surgeon and trainees was the operation time (92.3±32.2 min vs. 141.2±54 min, p<.001), while the myoma number, myoma diameter, myoma weight, and intraoperative blood loss were not significantly different. The operation time did not differ among different myoma locations. In multivariate analysis, virginity, myoma number, more than 2 large myomas, and myoma size were independent variables for longer operation times. No patient experienced any major complications. The result revealed that LETS-M is a minimally invasive surgical method that is safe, effective, and easy to learn for managing uterine myoma.

Fracture Surgery

Three-dimensional technology is increasingly being used in acetabular fracture treatment. No systematic reviews are available about the added clinical value of 3D-assisted acetabular fracture surgery compared to conventional surgery. Therefore, this study aimed to investigate whether 3D-assisted acetabular fracture surgery compared to conventional surgery improves surgical outcomes in terms of operation time, intraoperative blood loss, intraoperative fluoroscopy usage, complications, and postoperative fracture reduction, and whether it improves physical functioning. Pubmed and Embase databases were searched for articles on 3D technologies in acetabular fracture surgery, published between 2010 and February 2021. The McMaster critical review form was used to assess the methodological quality. Differences between 3D-assisted and conventional surgery were evaluated using the weighted mean and odds ratios. Nineteen studies were included. Three-dimensional-assisted surgery resulted in significantly shorter operation times (162.5 ± 79.0 versus 296.4 ± 56.0 min), less blood loss (697.9 ± 235.7 mL versus 1097.2 ± 415.5 mL), and less fluoroscopy usage (9.3 ± 5.9 versus 22.5 ± 20.4 times). The odds ratios of complications and fracture reduction were 0.5 and 0.4 for functional outcome in favour of 3D-assisted surgery, respectively. Three-dimensional-assisted surgery reduces operation time, intraoperative blood loss, fluoroscopy usage, and complications. Evidence for the improvement of fracture reduction and functional outcomes is limited.

Abstract Background Cubitus varus is a complex three-dimensional deformity. Various osteotomies have been introduced to correct this complex deformity. The objective of the present study was to evaluate clinical and functional outcomes of adult cubitus varus deformity treated with translation step-cut osteotomy. Methods Seventeen consecutive patients with a mean age of 25 years (range, 19–50 years) who underwent translation step-cut osteotomy were enrolled in this study. Their average follow-up period was 28.2 months. Radiographic measurements preoperatively, 3-month postoperatively, and at the last follow-up were compared. Functional outcomes were assessed using Disabilities of the Arm, Shoulder and Hand (DASH), Mayo Elbow Performance Score (MEPS), and Oppenheim criteria. Results The mean humerus–elbow–wrist angle improved from 14.7° ± 6.4° (range, 6°–23°) varus preoperatively to 12.1° ± 6.6° (range, 5°–20°) valgus postoperatively (p < 0.001). The lateral prominence index improved 9.6% from its preoperative value, showing no significant difference from that of a normal elbow. Osseous union was radiographically demonstrated in 16 patients (except one out of 17 patients) within a mean of 12.7 weeks (range, 8–18 weeks). The motion arc of the elbow at the last follow-up was not significantly (p > 0.05) different from that at the initial presentation. Based on Oppenheim criteria, results were excellent for 7, good for 8, and poor for 2 patients. Mean final DASH value and MEPS were 2.5 ± 3.8 points (range, 0–15 points) and 97.0 ± 5.8 points (range, 85–100 points), respectively. With regard to complications, one case had delayed union and one case had transient radial nerve injury. Conclusion Translation step-cut osteotomy using Y plate is an efficient procedure to correct varus alignment and flexion-extension deformities so that they are within normal limits of adults with post-traumatic cubitus varus deformity.

Abstract Objective To investigate the clinical effect of individualized 3D printing guide assisted upper cervical pedicle screw placement. Methods Eighteen patients with upper cervical spine injury requiring surgical treatment were included in our hospital from May 2010 to May 2019. These patients were divided into guide plate assisted screw implantation group (Group A, N = 10) and traditional operation group (Group B, N = 8). All patients were followed up for more than 6 months. Screw implant accuracy, cervical spine JOA score, ASIA score, VAS score, operation time, intraoperative blood loss were compared between the two groups. Result A total of 72 atlantoaxial pedicle screws were implanted, 40 in group A and 32 in group B. The accuracy rate of nail implantation was 97.50% in group A and 81.25% in group B (P < 0.05). The operation time in group A (189.7 ± 16.1 mins) and group B (242.1 ± 23.2 mins), P < 0.05. The intraoperative blood loss in group A (216.0 ± 49.7 ml) and group B (385.0 ± 23.5 ml), P < 0.05. The intraoperative fluoroscopic times was 8.7 ± 1.1 in group A and 30.0 ± 3.3 in group B (P < 0.05). Besides, the JOA, Asia and VAS scores of the two groups at one week after operation and the last follow-up were significantly different from those before operation. One week after operation, the JOA, Asia and VAS scores of group A were significantly better than those of group B, but there was no significant difference between the two groups at the last follow-up. Conclusions individualized 3D printing guide assisted placement of upper cervical pedicle screw can significantly improve the accuracy of screw implantation and postoperative function of patients, reduce the times of X-ray fluoroscopy, operation time, and intraoperative blood loss, which is a safe and effective approach and worthy of clinical promotion.
