RESUMO
Context: Calcaneal fractures (CFs) are the most common kind of tarsal fracture. The choice of surgical approach is a key element in the management of CFs, but the best method remains in dispute. Also, no single approach is appropriate for all kinds of CFs. Objective: The study intended to evaluate the relationship between six surgical approaches for clinical treatment of CFs and prevention of postoperative complications, to provide an evidence-based approach for treatment. Design: The research team performed a meta-analysis using the data from a previously published review and updating that data through a new narrative review. The team performed a systematic search in PubMed, Embase, the Cochrane Library, and the Chinese National Knowledge Internet (CNKI) from inception until January 2022, with no language restrictions. The search used the following keywords for the search: calcaneus, heel bone, surgical wounds, surgical incisions, prospective trials, prospective trials, and randomized controlled trials. Outcome Measures: The research team compared the complication rates, American Orthopedic Foot and Ankle Society (AOFAS) scores, and Bohler's angles for the six surgical approaches, which were: (1) the extensive lateral approach (ELA), (2) the sinus tarsi approach (STA), (3) the horizontal arc approach (HAA), (4) the longitudinal approach (LA), (5) the oblique lateral incision (OLI), and (6) the modified incision (MI)). The team summarized the results using a random effects model. Results: The research team analyzed the data from 19 RCTs with 1521 participants. They all were randomized controlled trials (RCTs). The complication rates were available for 18 studies, which included 1474 participants. The rates were significantly lower: (1) for HAA compared to ELA, [OR=-2.03; 95% CrI: [-3.63, -0.43)]; (2) for LA compared to ELA (OR=-1.83; 95% CrI: [-2.83, -0.84]); and (3) for STA compared to ELA (OR=- 1.22; 95% CrI: [-1.67, -0.78]). Of the 19 studies, 11 RCTs, with 942 participants, used the AOFAS scale. The probabilities for the surface under the cumulative ranking curve (SUCRA) indicated that OLI (0.694 ) >LA (0.596) >HAA (0.51) >STA (0.477) >ELA (0.224). In addition, ELA had the worst SUCRA (0.224). Of the 19 studies, 15 RCTs, with 1376 participants, used the Bohler angle as an outcome measure. The probability of SUCRA for the surgical approaches indicated that LA (0.723) >ELA (0.667) >STA (0.468) >HAA (0.373) >MI (0.27). Conclusions: The meta-analysis provides an evidence-based approach to the clinical treatment of CFs for six surgical approaches. HAA had the best outcomes, and ELA had the worst.
RESUMO
Fracture is a global public health disease. Bone health and fracture risk have become the focus of public and scientific attention. Observational studies have reported that tea consumption is associated with fracture risk, but the results are inconsistent. The present study used 2-sample Mendelian randomization (MR) analysis. The inverse variance weighted method, employing genetic data from UK Biobank (447,485 cases) of tea intake and UK Biobank (Genome-wide association study Round 2) project (361,194 cases) of fractures, was performed to estimate the causal relationship between tea intake and multiple types of fractures. The inverse variance weighted indicated no causal effects of tea consumption on fractures of the skull and face, shoulder and upper arm, hand and wrist, femur, calf, and ankle (odds ratio = 1.000, 1.000, 1.002, 0.997, 0.998; P = .881, 0.857, 0.339, 0.054, 0.569, respectively). Consistent results were also found in MR-Egger, weighted median, and weighted mode. Our research provided evidence that tea consumption is unlikely to affect the incidence of fractures.

To reduce pain after total hip replacement (THR), researchers are interested in drug-free interventions. However, there is still a lack of consensus on their prevention efficacy. We performed a meta-analysis to evaluate the use of nonpharmaceutical interventions for postoperative pain management after THR. We searched the Cochrane Library, MEDLINE, EMBASE, Web of Science, PEDRO, and ClinicalTrials.gov databases for articles published between and 1991 and 2020. The main outcome measures were postoperative pain, opioid consumption, and quality of life (QoL). In total, 1,942 patients were studied. We found moderate evidence indicating postoperative pain relief measured by the Western Ontario and McMaster Universities Arthritis Index Scale, with mean differences (MDs) of -0.28 (95% confidence interval [CI], -0.49 to -0.07; P=0.01; I2 =0%) within three months, -0.19 (95% CI, -0.40 to 0.02; P=0.07; I2 =0%) between 3-6 months, and -0.13 (95% CI, -0.35 to 0.08; P=0.21; I2 =0%) between 6-12 months. Additionally, we found that acupuncture therapy could reduce opioid analgesic consumption (MD, -0.98; 95% CI, -1.18 to -0.79; fentanyl [mg/h]; P<0.01; I2 =72.2%) and significantly improve pain relief with an MD of 0.90 (95% CI, 0.47 to 1.33; P<0.01; I2 =0%) measured using the visual analog scale. Electrotherapy slightly improved perceived pain with an MD of 0.22 (95% CI, -0.27 to 0.70; P=0.37; I2 =0%). Moreover, moderate evidence has shown that preoperative exercises improve QoL. This meta-analysis suggested that continuous passive motion did not improve pain or QoL. Postoperative exercise was associated with pain relief and improved QoL. Acupuncture therapy after THR has been shown to reduce opioid analgesic consumption.
RESUMO
Drynariae Rhizoma (DR) has been demonstrated to be effective in promoting fracture healing in clinical use. In the study, we tried to predicate potential signaling pathways and active ingredients of DR via network pharmacology, uncover its regulation mechanism to improve large bone defects by in vivo and in vitro experiment. We total discovered 18 potential active ingredients such as flavonoids and 81 corresponding targets, in which mitogen-activated protein kinase (MAPK) signaling pathway has the highest correlation with bone defects in pathway and functional enrichment analysis. Therefore, we hypothesized that flavonoids in DR improve large bone defects by activating MAPK signaling pathway. Animal experiments were carried out and all rats randomly divided into TFDR low, medium, and high dosage group, model group and control group. 12 weeks after treatment, according to X-ray and Micro-CT, TFDR medium dosage group significantly promote new bone mineralization compared with other groups. The results of HE and Masson staining and in vitro ALP level of BMSC also demonstrated the formation of bone matrix and mineralization in the TFDR groups. Also, angiographic imaging suggested that flavonoids in DR promoting angiogenesis in the defect area. Consistently, TFDR significantly enhanced the expression of BMP-2, RUNX-2, VEGF, HIF-1 in large bone defect rats based on ELISA and Real-Time PCR. Overall, we not only discover the active ingredients of DR in this study, but also explained how flavonoids in DR regulating MAPK signaling pathway to improve large bone defects.
