Although the recent trend is to postpone surgery until the daytime, the effect of after-hours surgery on outcomes requires further elucidation. Thus, we aimed to evaluate whether the timing of surgery for pediatric supracondylar humeral fractures affects the outcomes. The data of 135 pediatric patients who underwent surgery for Gartland type III supracondylar humeral fractures at a single trauma center were retrospectively analyzed. Depending on the time of admission to the operating room, the patients were divided into daytime and after-hours surgery cohorts. Nearest-neighbor propensity score matching was conducted, and outcomes were compared between the matched cohorts. The primary outcome was defined as reduction failure, including revision surgery. Secondary outcomes included the operative time, indication for open reduction, and complications. Each matched cohort consisted of 48 patients, with a mean age of 6.6 ± 2.6 years. The after-hours surgery resulted in more frequent reduction failures than the daytime surgery (21% vs. 4%, P < 0.05). No significant differences were observed in the secondary outcomes. In the post hoc analysis, where the matched cohorts were stratified by the presence of supervising orthopedic trauma surgeons, reduction failure rates showed no statistically significant difference between daytime and after-hours surgery. This propensity score-adjusted retrospective study revealed that reduction failures occurred more frequently in after-hours surgeries than in daytime surgeries for pediatric supracondylar humeral fractures. The absence of supervising surgeons may have contributed to the poorer outcome of after-hours surgeries.","PeriodicalId":50092,"journal":{"name":"Journal of Pediatric Orthopaedics-Part B","volume":" ","pages":"567-572"},"PeriodicalIF":1.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144977143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data of 91 cases of acute osteomyelitis in children with Staphylococcus aureus infection (including 29 cases of MRSA and 62 cases of MSSA) from July 2017 to March 2024 were retrospectively analyzed. Age, sex, duration of onset, maximum body temperature at onset, and inflammatory indicators detected after admission were compared between the MRSA group and the MSSA group. According to the receiver operating characteristic (ROC) curve, the diagnostic efficiency of MRSA infection was evaluated. Logistic regression analysis was used to determine independent risk factors for MRSA infection. There were no significant differences in age, sex, duration of onset, maximum body temperature, white blood cell count, neutrophil count, and erythrocyte sedimentation rate between the MRSA group and the MSSA group ( P > 0.05). The median C-reactive protein in the MRSA group and the MSSA group was 97.93 and 58.10 mg/L, respectively, with statistical significance ( P < 0.05). The sensitivity, specificity, and area under the curve of C-reactive protein for detecting MRSA infection were 41.4, 90.3, and 0.646%, respectively. Logistic regression analysis showed that C-reactive protein greater than 116.46 mg/L (odds ratio = 6.588, 95% confidence interval: 2.149-20.197) was an independent risk factor for predicting MRSA infection ( P < 0.05).

A retrospective analysis was performed involving 18 patients with ALBT treated with the 'U'-shaped staple-guided growth technique between January 2020 and October 2022 at two centres. Anteroposterior and lateral radiographs of both lower limbs and the tibia as well as the fibula were collected before surgery, at the time of implant removal, or at the last follow-up. Changes in the coronal tibial diaphyseal angulation, sagittal tibial diaphyseal angulation, anatomical medial proximal tibial angle (aMPTA) and anatomical lateral distal tibial angle (aLDTA) were statistically analysed to evaluate the correction effect of the ALBT. All patients were followed up for an average of 23.36 months (range: 14.53-37.2 months). All 18 patients demonstrated an improvement in the coronal plane tibial shaft angle, with an average correction of 17.94° (range: 5.54°-33.52°). Fourteen patients displayed an improvement in the sagittal plane tibial shaft angle, with an average correction of 13.44° (range: 1.89°-32.6°). Both the aMPTA and aLDTA levels decreased after treatment. No tibial pseudarthrosis occurred in any of the 18 patients during the follow-up. The guided growth technique is effective in improving the ALBT, preventing further angular deformities of the tibia, and may delay or prevent tibial pseudarthrosis. Moreover, the guided growth technique is simple to perform, minimally invasive and associated with few complications.","PeriodicalId":50092,"journal":{"name":"Journal of Pediatric Orthopaedics-Part B","volume":" ","pages":"608-615"},"PeriodicalIF":1.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12487664/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143191188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty synthetic femur models with identical, length-unstable, spiral fractures were tested using a three-dimensional camera system to assess real-time micromotion. Three groups were analyzed: (a) 2CS - two 3.5 mm C- and S-shaped nails inserted anterograde, (b) 2CL - one 'C' and one 'S' shaped 3.5 mm titanium nail-inserted retrograde from a single lateral entry, (c) 3CL - two 'C' shaped 3.5 mm titanium nails inserted medially and laterally with a third 'C' shaped 2.5 mm nail placed retrograde from an anterolateral site.

This study aimed to evaluate and summarize the orthopedic manifestations associated with AT. A retrospective review was conducted of patients with AT. Reported outcomes included demographics, orthopedic manifestations and operative/nonoperative treatments, radiographic exposure, development of malignancy, and ambulatory status (using the Functional Mobility Scale at 50 m, FMS50). Twenty-four children were included [11 (45.8%) female] with a mean age at diagnosis of 5.5 (SD = 3.5) years. The most common reason for orthopedic consultation was ataxia; 12 (50%) were walkers (FMS50 = 4,5) and 12 nonwalkers (FMS50 = 1,2).

A retrospective analysis of 27 SMA patients (mean age 13.4 ± 4.3 years) who underwent scoliosis surgery between 2015 and 2019 was conducted. Preoperative VR was measured using Aaro-Dahlborn's and Ho's methods on computed tomography images. Surgical outcome prediction was evaluated using the Pearson correlation coefficient, linear stepwise regression, receiver operating characteristic (ROC) curve, and logistic regression analyses. Ho's method yielded significantly higher VR measurements than Aaro-Dahlborn's ( P < 0.001). Postoperative Cobb angles correlated positively with preoperative Cobb angles ( r ² = 0.425, P = 0.0002), Ho's method VR ( r ² = 0.449, P = 0.0001), and Aaro-Dahlborn's method VR ( r ² = 0.4352, P = 0.0002). Stepwise regression identified preoperative Ho's method VR and Cobb angles as independent predictors of postoperative Cobb angles. Postoperative Cobb angles >30 ° indicated increased risk of deformity progression in SMA. ROC curve analysis showed preoperative Ho's method VR significantly predicted postoperative Cobb angles >30 ° (area under the curve: 0.813, P = 0.006), with an optimal cutoff of 35 °. Logistic regression analysis revealed patients with preoperative Ho's method VR > 35 ° had a higher risk of postoperative Cobb angles >30 ° (odds ratio: 10.36, 95% confidence interval: 1.050-102.261, P = 0.045).
