Purpose
-
Different deep-learning models have been employed to aid in the diagnosis of musculoskeletal pathologies. The diagnosis of tendon pathologies could particularly benefit from applying these technologies. The objective of this study is to assess the performance of deep learning models in diagnosing tendon pathologies using various imaging modalities.
Methods
-
A meta-analysis was conducted, with searches performed on MEDLINE/PubMed, SCOPUS, Cochrane Library, Lilacs, and SciELO. The QUADAS-2 tool was employed to assess the quality of the studies. Diagnostic measures, such as sensitivity, specificity, diagnostic odds ratio, positive and negative likelihood ratios, area under the curve, and summary receiver operating characteristic, were included using a random-effects model. Heterogeneity and subgroup analyses were also conducted. All statistical analyses and plots were generated using the R software package. The PROSPERO ID is CRD42024506491.
Results
-
Eleven deep-learning models from six articles were analyzed. In the random effects models, the sensitivity and specificity of the algorithms for detecting tendon conditions were 0.910 (95% CI: 0.865; 0.940) and 0.954 (0.909; 0.977). The PLR, NLR, lnDOR, and AUC estimates were found to be 37.075 (95%CI: 4.654; 69.496), 0.114 (95%CI: 0.056; 0.171), 5.160 (95% CI: 4.070; 6.250) with a (P < 0.001), and 96%, respectively.
Conclusion
-
The deep-learning algorithms demonstrated a high level of accuracy level in detecting tendon anomalies. The overall robust performance suggests their potential application as a valuable complementary tool in diagnosing medical images.

Purpose
-
The aim of this systematic review and meta-analysis is to explore the effect of topical vancomycin powder (VP) in surgical site infection (SSI) prevention and adverse events after joint arthroplasty and to provide a specific theoretical basis for clinical treatment.
Methods
-
The review process was conducted according to the PRISMA guidelines. Two independent researchers meticulously screened the literature based on predefined inclusion and exclusion criteria, evaluated the quality of the selected studies, and extracted relevant data. Data analysis was conducted using RevMan 5.4 software.
Results
-
This meta-analysis included 24 studies encompassing a total of 34 811 patients. The pooled analysis showed that the topical administration of VP significantly reduced the incidence of SSI. Subgroup analyses by doses, type of joint (hip and knee), and type of surgery (primary and revision) confirmed that vancomycin consistently lowered SSI rates. Moreover, the incidence of SSI caused by gram-negative germs and gram-positive germs decreased following the use of VP, although the reduction was not significant for infections caused by MRSA. However, the use of VP was associated with a significant increase in sterile complications at the incision site and delayed incision healing.
Conclusion
-
The topical application of VP is effective in reducing the incidence of infections following joint arthroplasty. Despite an increased risk of complications such as delayed healing of incisions, the pros and cons should be weighed in clinical decision-making. However, it should not be discarded due to side effects.

-
Advanced therapies are expected to play a crucial role in supporting repair after injury, halting the degeneration of musculoskeletal tissue to enable and promote physical activity.
-
Despite advancements, the progress in developing advanced therapies in orthopaedics lags behind specialties like oncology, since innovative regenerative treatment strategies fall short of their expectations in musculoskeletal clinical trials.
-
Researchers should focus on understanding the mechanism of action behind the investigated target before conducting clinical trials.
-
Strategic research networks are needed that not only enhance scientific exchange among like-minded researchers but need to include early on commercial views, companies and venture perspectives, regulatory insights and reimbursement perspectives. Only in such collaborations essential roadblocks towards clinical trials and go-to-patients be overcome.

Objective
-
The aim of the study was to evaluate the efficacy and safety of teriparatide compared to other treatments for postmenopausal osteoporosis.
Methods
-
A review of studies from 2000 to January 2023 analyzed randomized controlled trials on postmenopausal women treated with teriparatide (PTH 1–34), comparing it to placebo or other osteoporosis treatments. The analysis focused on bone mineral density (BMD), bone turnover markers, and clinical outcomes, employing Review Manager 5.4.1 and the RoB 2 tool for bias assessment.
Results
-
Our analysis of 23 randomized controlled trials (RCTs) found that PTH (134) treatment significantly increased lumbar spine BMD (mean difference (MD) = 0.02, 95% CI: 0.01–0.03) and femoral neck BMD (MD = 0.01, 95% CI: 0.00–0.01). However, there were no significant changes in total hip and radial bone BMD among the 3536 and 2046 participants, respectively. We also found that PTH (1–34) increased P1NP in a larger cohort (n = 1415) when compared to osteocalcin (n = 206). Although the risk of adverse events increased (relative risk (RR) = 1.65, 95% CI: 1.32–2.07), the incidence of fractures decreased significantly (RR = 0.57, 95% CI: 0.45–0.072), with no significant difference observed in mortality rates between treatment and control groups.
Conclusion
-
Teriparatide improves lumbar spine and femoral neck BMD in postmenopausal women. Particularly notable is the novel finding regarding its effect on radius BMD, an area less explored in previous research. Despite an uptick in adverse events, the marked decrease in fracture incidence confirms its clinical utility for high-risk osteoporosis patients, highlighting the necessity for ongoing investigations into its full skeletal effects.

Ferroptosis is a novel form of programmed cell death, distinguished from apoptosis, autophagy, and programmed necrosis and has received much attention since it was defined in 2012.
-
Ferroptotic cells physiologically exhibit iron metabolism dysregulation, oxidative stress, and lipid peroxidation. Morphologically, they show plasma membrane disruption, cytoplasmic swelling, and mitochondrial condensation.
-
Osteoporosis is taken more and more seriously as the proportion of the aging population continues to increase globally. Interestingly, ferroptosis has been demonstrated to be involved in the development and progression of osteoporosis in many extant studies.
-
The review summarizes iron metabolism, lipid peroxidation, and the different regulatory signals in ferroptosis. Changes in signaling mechanisms within osteoblasts, osteoclasts, and osteocytes after ferroptosis occur are explained here.
-
Studies showed ferroptosis play an important role in different osteoporosis models (diabetes osteoporosis, postmenopausal osteoporosis, glucocorticoid-induced osteoporosis). Inhibitors and EC (Exos) targeting ferroptosis could ameliorate bone loss in osteoporotic mice by protecting cells against lipid peroxidation. Shortly, we hope that more effective and appropriate clinical therapy means will be utilized in the treatment of osteoporosis.

Purpose
-
The aim of this study was to investigate the efficacy of calcitonin (CT) in animal models of experimental osteoarthritis (OA) and rheumatoid arthritis (RA), as new stabilized CT formulations are currently being introduced.
Methods
-
A comprehensive and systemic literature search was conducted in PubMed/MEDLINE and Embase databases to identify articles with original data on CT treatment of preclinical OA and RA. Methodological quality was assessed using the Systematic Review Centre for Laboratory Animal Experimentation’s risk of bias tool for animal intervention studies. To provide summary estimates of efficacy, a meta-analysis was conducted for outcomes reported in four or more studies, using a random-effects model. Subgroup analyses were employed to correct for study specifics.
Results
-
Twenty-six studies were ultimately evaluated and data from 16 studies could be analyzed in the meta-analysis, which included the following outcomes: bone mineral density, bone volume, levels of cross-linked C-telopeptide of type I collagen, histopathological arthritis score, and mechanical allodynia. For all considered outcome parameters, CT-treated groups were significantly superior to control groups (P = 0.002; P = 0.01; P < 0.00001; P < 0.00001; P = 0.04). For most outcomes, effect sizes were significantly greater in OA than in RA (P ≤ 0.025). High in-between study heterogeneity was detected.
Conclusion
-
There is preclinical evidence for an antioxidant, anti-inflammatory, antinociceptive, cartilage- and bone-protective effect of CT in RA and OA. Given these effects, CT presents a promising agent for the treatment of both diseases, although the potential seems to be greater in OA.

Total joint arthroplasty (TJA) is rising globally, with an associated increase in associated complications, necessitating increased efforts in prevention of these complications with pre-operative optimisation.
-
Malnutrition has been highlighted as one of the most important pre-operative modifiable risk factors to be addressed in TJA, with the term malnutrition in orthopaedic surgery having a broad definition that encompasses a wide range of nutritional abnormalities from undernutrition to overnutrition contributing to the outcomes of TJA.
-
Complications associated with malnutrition include periprosthetic joint infection (PJI), periprosthetic fracture, dislocations, aseptic loosening, anaemia, prolonged length of stay (LOS), increased mortality, and raised health care costs.
-
Standardised nutritional scoring tools, anthropometric measurements, and serological markers are all options available in pre-operative nutritional assessment in TJA, but there is no consensus yet regarding the standardisation of what parameters to assess and how to assess them.
-
Abnormal parameters identified using any of the assessment methods results in the diagnosis of malnutrition, and correction of these parameters of overnutrition or undernutrition have shown to improve outcomes in TJA.
-
With the multiple nutritional parameters contributing to the success of total joint arthroplasty, it is imperative that orthopaedic surgeon has a thorough knowledge regarding nutritional peri-operative optimisation in TJA.

Myositis ossificans (MO) is characterized by benign heterotopic ossificans in soft tissues like muscles, which can be classified into nonhereditary MO and fibrodysplasia ossificans progressiva (FOP). Although MO has been studied for decades, no research reviewed and analyzed the features of publications in this field quantitatively and qualitatively.
-
Using bibliometrics tools (bibliometrix R package, VOSviewer, and CiteSpace), we conducted a bibliometric analysis of 1280 articles regarding MO in the Web of Science Core Collection database from 1993 to 2022.
-
The annual number of publications and related research areas in the MO field increased gradually in the past 20 years. The USA contributed the most percentage (42.58%) of articles. The University of Pennsylvania (UPenn) and the Journal Bone published the most articles among all institutions and journals. Kaplan FS and Shore EM from UPenn were the top two scholars who made the largest contributions to this field.
-
Keyword analysis showed that research hotspots changed from traumatic MO and clinical management of MO to the genetic etiology, pathogenesis, and treatment of FOP.
-
This study can provide new insights into the research trends of MO and helps researchers grasp and determine future study directions more easily.

Purpose
-
For many decades, patients recovering from wound closure have been instructed not to bathe. Although studies have shown that earlier postoperative bathing does not increase the risk of wound infection, it remains rare in practice for patients to be allowed earlier postoperative bathing. We performed this meta-analysis to determine how earlier bathing affected rates of wound infection, other complications, and patient satisfaction.
Methods
-
This systematic review conforms to PRISMA guidelines. The PubMed, EMBASE, Medline, Web of Science, and the Cochrane Central Register of Controlled Trials were searched from their inception dates to December 31, 2022. We estimated pooled values for the efficacy of trial of earlier bathing versus delayed bathing using the odds ratio and their associated 95% CI, and we used the I 2 statistic to assess heterogeneity between studies contributing to these estimates.
Results
-
Of the 1813 articles identified by our search, 11 randomized controlled trials including 2964 patients were eligible for inclusion. The incidence of wound infection did not differ significantly between the earlier bathing and delayed bathing groups, nor did rates of other wound complications such as redness and swelling, or wound dehiscence. However, the incidence of hematoma in the delayed bathing group was higher than in the earlier bathing group. Reported patient satisfaction was significantly higher in the earlier bathing group.
Conclusion
-
The medical community, health authorities, and government should create and disseminate clinical practice guidelines to guide patients to evidence-based beneficial treatment.

Purpose
-
This study sought to determine if the use of tranexamic acid (TXA) in preexisting thromboembolic risk patients undergoing total joint arthroplasty (TJA) was linked to an increased risk of death or postoperative complications.
Methods
-
We conducted a comprehensive search for studies up to May 2023 in PubMed, Web of Science, EMBASE, and the Cochrane Library. We included randomized clinical trials, cohort studies, and case–control studies examining the use of TXA during TJA surgeries on high-risk patients. The Cochrane Risk of Bias instrument was used to gauge the excellence of RCTs, while the MINORS index was implemented to evaluate cohort studies. We used mean difference (MD) and relative risk (RR) as effect size indices for continuous and binary data, respectively, along with 95% CIs.
Results
-
Our comprehensive study, incorporating data from 11 diverse studies involving 812 993 patients, conducted a meta-analysis demonstrating significant positive outcomes associated with TXA administration. The findings revealed substantial reductions in critical parameters, including overall blood loss (MD = −237.33; 95% CI (−425.44, −49.23)), transfusion rates (RR = 0.45; 95% CI (0.34, 0.60)), and 90-day unplanned readmission rates (RR = 0.86; 95% CI (0.76, 0.97)). Moreover, TXA administration exhibited a protective effect against adverse events, showing decreased risks of pulmonary embolism (RR = 0.73; 95% CI (0.61, 0.87)), myocardial infarction (RR = 0.47; 95% CI (0.40–0.56)), and stroke (RR = 0.73; 95% CI (0.59–0.90)). Importantly, no increased risk was observed for mortality (RR = 0.53; 95% CI (0.24, 1.13)), deep vein thrombosis (RR = 0.69; 95% CI (0.44, 1.09)), or any of the evaluated complications associated with TXA use.
Conclusion
-
The results of this study indicate that the use of TXA in TJA patients with preexisting thromboembolic risk does not exacerbate complications, including reducing mortality, deep vein thrombosis, and pulmonary embolism. Existing evidence strongly supports the potential benefits of TXA in TJA patients with thromboembolic risk, including lowering blood loss, transfusion, and readmission rates.
