Abstract Objective This study was designed for the first time to analyze clinical efficacy of bone transport technology in Chinese older patients with infectious bone nonunion after open tibial fracture. Methods This study retrospectively analyzed 220 older patients with infectious bone nonunion after open tibial fracture. There were 110 patients receiving bone transport technology (Group A) and 110 patients receiving membrane induction technique with antibiotic bone cement (Group B). Results There were 164 male patients and 56 female patients, with an age range of 65 to 71 years and an average age of 67 ± 1.3 years. Traffic accident, high-fall injury and crush injury account for 45.5, 27.7 and 26.8%, respectively. Age, gender, histories, causes and fracture location had no significant difference between the two groups (P > 0.05 for all). Operation time in the Group A was significantly shorter than that in the Group B (P < 0.05). Linear and positional alignment (70.9 vs. 57.3), American Knee Society knee function score (167.7 ± 14.9 vs. 123.8 ± 15.7), Baird-Jackson ankle function score (89.9 ± 3.5 vs. 78.4 ± 4.9), bone healing index (43.0 ± 2.0 vs. 44.3 ± 3.0) and clinical recovery (8.2 vs. 4.5) of patients in the Group A were significantly better than those in the Group B (P < 0.05 for all). Wound infection in the Group A (7.3%) was significantly less than that in the Group B (16.4%; P < 0.05). There were neither a neurovascular complication nor a recurrence of infection in the two groups. Conclusion Bone transport technology achieved better knee and ankle joint function recovery and superior bone healing and clinical efficacy than membrane induction technique with antibiotic bone cement, suggesting that bone transport technique is worthy of extensive promotion to improve clinical condition of older patients with infectious bone nonunion after open tibial fracture.

Treatment of congenital pseudarthrosis of the tibia remains a major challenge in pediatric orthopedics. Ideal timing and preference of surgical procedures are discussed controversially. A variety of reconstructive treatment strategies have been described in literature, but so far none has proven its superiority. The aim of treatment is to obtain long-term bone union, to prevent refracture, and to correct angular deformities and leg length discrepancies. This study retrospectively evaluates the outcome of different reconstructive strategies. Sixty-nine patients were identified who presented to our outpatient department between 1997 and 2019. Twenty-six of these patients underwent reconstructive surgical treatment and were included in this study. The study cohort was divided into three groups. Excision of the pseudarthrosis was performed in all patients in Group A and B, and in two patients of Group C. Group A (six/26 patients) received subsequent bone transport through external fixation maintaining original length. In Group B (15/26 patients), patients underwent either previous, simultaneous, or subsequent extrafocal lengthening through external fixation to reconstitute length. In Group C (five/26 patients), internal fixation with intramedullary nails was applied. Radiological and clinical evaluation was performed to assess bone union and complication rates. Results varied considerably between the study groups. Overall, the primary bone fusion rate was 69.2%. There were four refractures, all occurring in Group B. The long-term bone union rate without refracture was 53.8%. The overall complication rate was 53.8% and 23.1% showed persistent pseudarthrosis. Two secondary amputations were performed due to failed bone fusion. In conclusion, excision of the pseudarthrosis and extrafocal lengthening achieves a satisfying bone union rate and limb reconstruction, while bone transport does not offer significant advantages but shows higher complication rates. Intramedullary stabilization should be applied to maintain bone union, but shows lower bone union rates when used as a stand-alone treatment regimen. Regardless of the primary bone fusion rates, the probability of long-term bone union remains unpredictable.

Animal Experimental Model

Purpose. Open lower leg fractures are frequently associated with severe soft tissue damage, followed by osteomyelitis. Using an animal experimental model, we investigated the effect of timing of coverage of a tibial fracture with a local muscle flap. Methods. 80 rabbits had a tibial fracture induced in a standardised fashion, which was stabilised by screw osteosynthesis. After 3 (group A; n=40) and 7 days (group B; n=40), respectively, the tissue defect was covered by a local gastrocnemius flap. In increasing intervals from 1 to 2, 4, 8, and 16 weeks, the rabbits from each group were killed and the bone fracture was analysed histomorphologically Cortical microcirculation was measured by 2-channel laser doppler flowmetry. Results. Muscle flaps after 3 days improved perfusion significantly as compared with 7 days (24 Flux [standard error, 5 Flux] versus 10 Flux [3 Flux]; baseline, 1.4 Flux). Group A animals also displayed a lower rate of necrosis (0 versus 38). The incidence of osteomyelitis was higher in group B than in group A (24% versus 0%). Conclusion. Laser doppler flowmetry was proven to be a reliable, minimally invasive means for identifying avital tissue, leading to reduction in the loss of vital bone tissue in experimental settings.

Abstract Background The aim of this study is to explore the use of preoperative imaging stability studies of adult lumbar spondylolisthesis and it's effects on intraoperative correction, postoperative observation, and clinical efficacy. Methods We retrospectively analyzed a total of 104 patients diagnosed with lumbar spondylolisthesis who underwent Posterior lumbar interbody fusion surgery between 2011 and 2014. The qualified patients were divided into two groups; group A (study/unstable group: 52 cases) and group B (control/stable group: 52 cases). Group A was further divided into group A1 (slip instability: 27 cases) and group A2 (angular instability: 25 cases). The preoperative lumbar sagittal plane translation distances and segmental angle of the preoperative lateral X-rays, hyperflexion X-rays, and hyperextension X-rays were measured and compared with their third-day postoperative lateral X-ray, and slip rate. The occurrences of intraoperative or postoperative complications, one-month postoperative follow-up data, including JOA, and VAS scores were access to evaluate the clinical efficacy of the treatment. Results Satisfactory postoperative radiographic correction was recorded in all groups. Better correction and correction was observed in group A1 patients and group B patients who used puller screws compared to those who used normal screws (P < 0.05). However, patients in group A2 who used normal pedicle screws had similar correction as those who used puller screws. The preoperative VAS scores showed that low back and lower extremity pain were higher in A1 and A2 groups compared to group B. However, they were lower one month postoperative. The preoperative JOA scores for the unstable groups (group A1 and A2) were lower than their stable counterpart but higher during the first month postoperative. Our analysis of postoperative complications also revealed no statistically significant difference between groups A1 and B, and groups A2, and B. Conclusions Preoperative imaging stability for adult lumbar spondylolisthesis does not affect intraoperative correction. The use of puller pedicle screws in patients with unstable or stable segmental slippage could achieve better correction and correction than with normal pedicle screws. The preoperative symptoms of patients with unstable segments were worse than their stable counterparts; however, their postoperative recovery was quicker in the first month postoperative.

e21605 Background: To observe the clinical efficacy and survival of UMIPIC combined with low-dose chemotherapy in patients with lung cancer. Methods: 840 patients with lung cancer underwent UMIPIC treatment from January 2011 to December 2015 were selected as the study subjects, 341 cases combined with low-dose chemotherapy in group A and 499 cases not combined with chemotherapy in group B. All patients were diagnosed with lung cancer and signed a consent form for treatment. The patients were treated according to the UMIPIC treatment guidelines. This study was mainly to observe the adverse reactions, clinical efficacy, survival time and survival rate of lung cancer patients after receiving UMIPIC combined with or without low dose chemotherapy. Results: The common adverse reactions in group A were fever 38.12%, followed by pain 9.38%, hemoglobin 7.94%, white blood cells 5.01%, nausea 2.35%, liver function damage 1.19%, vomiting 1.17%, and kidney function damage 0.30%; Common adverse reactions in group B were fever 38.68%, followed by pain 13.23%, hemoglobin reduction 12.87%, white blood cell reduction 5.29%, nausea 2.00%, vomiting 2.00%, liver function damage 1.92%. The hemoglobin reduction in group A was significantly lower than that in group B (P < 0.05), and there was no difference in the other adverse reactions (P > 0.05). Clinical efficacy of the two groups revealed that the benefit rate of group A was 95.45% higher than that of group B 93.47% (P > 0.05). After follow-up, it was found that the average survival time and median survival time of patients in group A were 20.744 and 13.270 months, respectively, which were significantly higher than those of group B at 19.514 and 10.070 months (P < 0.05). The survival rates of the two groups of patients, The 1-year, 2-year, and 5-year survival rates of group A patients are 52.48%, 23.60%, and 16.95%, and the 1-year, 2-year, and 5-year survival rates of group B patients are 42.96% and 17.07 % And 10.26%, the one-year survival rate of group A was significantly higher than that of group B (P < 0.05). Conclusions: UMIPIC combined with low-dose chemotherapy has a good clinical effect in treating lung cancer without increasing the incidence of adverse reactions, and a significant effect on extending survival time and improving survival rate of lung cancer patients.

e24014 Background: PROs are the gold standard to describe subjective symptoms. In order to improve clinical management of outpatients receiving active anti-cancer treatment at Medical Oncology, Mauriziano Hospital, Turin, Italy, in January 2018 we introduced in routine clinical practice an assessment of patient-reported symptoms and toxicities. We demonstrated that use of PROs in clinical practice was associated with a significant QoL improvement, compared to the traditional visit (Baratelli, Support Care Cancer 2019). In this secondary analysis, we show the results obtained in older pts ( > 70yrs). Methods: Eligible pts were receiving an active anti-cancer treatment, as outpatients. Pts treated in 2017 underwent “usual” visits (group A), while pts treated in 2018 before each visit received a paper questionnaire by a dedicated nurse, in order to provide information about symptoms and toxicities to be discussed during visit (group B). Primary objective was the comparison of QoL changes, measured by EORTC QLQ-C30. Results: Out of 211 pts, 88 were older than 70 yrs (47 group A, 41 group B). Median age was 76 (70-84 yrs). Most common tumors were colorectal (25.0%), lung (22.7%) and pancreatic (17.0%). 68.2% were receiving first-line treatment. Tumors and setting were similar between group A and B. Younger and older pts had comparable baseline QoL scores: mean global QoL score was 59.96 in younger pts vs. 57.39 in older pts. After 1 month, global QoL of older pts was significantly improved in group B compared to group A: mean change from baseline was -0.89 group A vs. +4.47 group B (p = 0.006, effect size 0.23). There were statistically significant differences in mean changes from baseline, in favor of group B, for role functioning (-5.67 group A and -0.81 group B, p = 0.034, effect size 0.20) and emotional functioning (-2.30 group A and +3.25 group B, p = 0.014, effect size 0.36). Mean changes from baseline for pain were significantly better for group B (-3.25) than group A (+6.03, p = 0.01, effect size 0.43). There were no significant differences between the 2 groups in terms of other functional scales or symptoms. There was no significant heterogeneity in the proportion of QoL responders between younger and older pts (p = 0.60). The proportion of older pts obtaining a clinically significant improvement in global QoL was numerically higher in group B (36.6%) compared to group A (19.1%, p = 0.09). Odds Ratio of obtaining an improvement in global QoL for group B vs group A was 1.73 (95%CI 0.75 – 3.99) in younger pts and 2.44 (95%CI 0.93 – 6.40) in older pts. Conclusions: This secondary analysis shows that the use of PROs in clinical practice, thanks to an active role of nurses and discussion of symptoms with physicians during the visit, is associated, also in older patients receiving active anticancer treatment, with a significant improvement in global QoL.

To explore the clinical efficacy of biomedical ceramic iRoot BP in the treatment of localized acute pulpitis in children, and the effect of iRoot BP on proliferation and osteogenic differentiation of human dental pulp stem cells (hDPSCs), 72 localized acute pulpitis children admitted to our hospital from September 2018 to September 2019 were selected and divided into group A (treated with MTA pulp capping material) and group B (treated with iRoot BP material), and the clinical effect, pain degree, and adverse reactions (ADR) rate were compared. The effects of iRoot BP on hDPSCs proliferation and osteogenic differentiation were analyzed; the proliferative activity of cells in iRoot BP group, MTA group, and control group (C group) were measured by cholecystokinin-8 (CCK-8) assay, the ability of cell mineralized nodular formation was observed via alizarin red staining; and quantitative reverse transcription PCR (qRT-PCR) andWestern blot were adopted to determine the expression of osteogenic related genes of hDPSCs and key proteins of mitogen-activated protein kinase (MAPK) signaling pathway. After 1 week of treatment, the clinical efficacy of group B was more favorable in contrast with group A (P < 0.05); the pain of children in group B was notably better in contrast with group A, and incidence of ADR was notably lower in contrast with group A (P < 0.05). 5.0 mg/mL, 10.0 mg/mL, and 30 mg/mL iRoot BP or MTA could improve cell proliferation activity (P < 0.01); the effect of iRoot BP on proliferation of hDPSCs was greater in contrast with MTA (P < 0.05); and the integral optical density (IOD) value of iRoot BP group was notably higher in contrast with MTA group (P < 0.01). The mRNA expression levels of collagen-I (COL-I), bone sialoprotein (BSP), and osteocalcin (OC) in MTA group and iRoot BP group were notably higher in contrast with C group (P < 0.01); the COL-I mRNA expression level of iRoot BP group was notably higher in contrast with MTA group (P < 0.01); the mRNA expression level of BSP in MTA group was notably higher in contrast with iRoot BP group (P < 0.01); the relative protein expression levels of phosphorylated ERK (p-ERK) and phospho-Jun N-terminal kinase (p-JNK) in MTA group and iRoot BP group were notably higher in contrast with C group (P < 0.01); and the relative expression level of p-ERK protein in iRoot BP group was higher in contrast with MTA group (P < 0.05). These results indicated that the clinical efficacy of biomedical ceramic iRoot BP was better than MTA in the preservation of live pulpitis in children, and the patients treated with iRoot BP had better pain recovery effect and lower risk of ADR. The effect of iRoot BP on the proliferation and mineralization of hDPSCs was better than that of MTA, and it may promote the osteogenic differentiation of hDPSCs by activating MAPK signaling pathway and regulating gene expression of COL-I, BSP, and OC.
