Ninety-three percent of the patients returned to sports within an average of 7.9 months (SD = 2.7 months). Fifty-three percent of the participants required a second intervention. Smart Nails were associated with a higher complication rate, whereas metal screws showed higher reoperation rates, primarily because of elective implant removal. Healing rates and functional outcomes were comparable across lesion location, fixation method, growth plate status, and lesion grade. Internal fixation for unstable JOCD in adolescents shows a high healing rate and a low rate of complications, with most patients successfully returning to sports within a year.

Intraoperative fluoroscopy is used to estimate the physeal midpoint for hardware placement; however, no standardized radiographic method has been established to identify this landmark. The purpose of this study was to determine the accuracy and reliability of three novel radiographic landmarks for approximating the distal femoral physeal midpoint. Perfect lateral digitally reconstructed radiographs of the knee were generated from computed tomography scans of pediatric patients using open-source image computing software. The physeal midpoint was identified and compared with three radiographic landmarks: the diaphyseal midpoint, the apex of the physeal undulation, and the inferior point of Blumensaat's line. The anteroposterior distance between each landmark and the physeal midpoint was measured, and intraclass correlation coefficients (ICCs) were calculated to assess reliability. Twenty-seven (71% male and 29% female) patients with a mean age of 13.6 ± 1.7 years were included. Relative to the physeal midpoint, the diaphyseal midpoint was 4.0 ± 2.4 mm anterior, the apex undulation was 1.6 ± 1.2 mm anterior, and the inferior Blumensaat's point was 1.2 ± 1.3 mm posterior. Reliability was good for the diaphyseal midpoint (ICC = 0.799) and apex undulation methods (ICC = 0.889), and excellent for the Blumensaat landmark (ICC = 0.987). These findings suggest that multiple radiographic landmarks can reliably approximate the distal femoral physeal midpoint on perfect lateral radiographs. The inferior point of Blumensaat's line demonstrated the greatest accuracy and reliability and may serve as a useful intraoperative guide for hardware placement during distal femoral guided growth procedures.Level of evidence: Level III.","PeriodicalId":50092,"journal":{"name":"Journal of Pediatric Orthopaedics-Part B","volume":" ","pages":"422-428"},"PeriodicalIF":0.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148347136","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}

A retrospective case series study was conducted on 15 adolescent patients (average age 10.67 years) with neglected congenital vertical talus from June 2020 to 2025, with a median follow-up of 24 months.

An understanding of torsional malalignment is critical in many subspecialty areas of orthopaedics including paediatric orthopaedics, deformity correction, sports medicine, hip and knee surgery, as well as trauma. This article aims to provide a reference system to objectively classify axial plane malalignment of the femur and tibia using the 'axial malalignment test' (AMAT). A cohort of patellofemoral dislocators and control subjects underwent bilateral lower limb MRI scans as part of a research protocol. Their femoral and tibial torsion were calculated on axial slices, and femoral torsion for each patient was plotted with respect to their tibial torsion. The resulting scatterplot was divided into a matrix based on normal values constructed from the dataset. Normal, simple, and complex torsional profiles were defined based on whether there was torsion greater than normal in neither, one, or both bones respectively. Measurements of foot progression angle were also compared in selected patients, with extension of the algorithm to include assessment of any soft tissue contribution to finalize descriptive and quantitative values for the AMAT. The AMAT offers a structured approach that incorporates both bony anatomy and soft tissue function to support systematic assessment of torsional deformities. Validation in a larger cohort is needed to confirm these preliminary findings, given the small sample size.","PeriodicalId":50092,"journal":{"name":"Journal of Pediatric Orthopaedics-Part B","volume":" ","pages":"502-508"},"PeriodicalIF":0.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147629184","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}

However, the utility of both angular deformity and LLD in HME has not been comprehensively evaluated. In this study, we retrospectively reviewed 25 pediatric patients with HME who visited our institution and reached skeletal maturity between 2012 and 2024, assessing a total of 50 limbs. Surgical indications included patients aged greater than 10 years with an open growth plate, predicted LLD of greater than or equal to 20 mm at the skeletal maturity, and a mechanical axis zone (MAZ) greater than or equal to Zone 2. We categorized the outcomes into four groups: excellent [LLD < 10 mm; mechanical axis percentage (%MA) ≤ ±25%], good (LLD < 15 mm; %MA ≤ ±50%), fair (LLD < 20 mm or at least one limb classified as %MA ≤ ±100%), and poor (worse than the previous categories). We used paired t -tests for statistical analyses. Among the 17 surgically treated patients, TBP was performed on 27 limbs and 60 physes. In most cases, multisite and staged surgeries were required. Angular deformities improved significantly, with the mean hip-knee-ankle angle reduced from 7.8 to 2.7° (lower extremity < 0.01), and 92% of limbs achieved MAZ Zone 1. LLD was corrected from 17.6 to 5.6 mm ( P < 0.01) at an average correction rate of 0.47 mm/month. The final outcomes were excellent, good, and fair or poor in 12, 11, and 2 patients, respectively.

Pedobarographic assessment provides objective information on plantar pressure distribution and may be useful for monitoring treatment-related changes. This prospective pretest-posttest study evaluated static and dynamic pedobarographic changes following University of California Biomechanics Laboratory (UCBL) orthosis use in 90 children aged 4-16 years with flexible pes planus. All participants used a UCBL orthosis for 3 months. Static and dynamic pedobarographic measurements were performed at baseline and after treatment. Regional plantar pressure and contact area were analyzed for both feet. After UCBL orthosis use, static assessment demonstrated significant reductions in plantar pressure, predominantly in the midfoot and forefoot regions ( P < 0.05). Significant reductions were also observed in maximal forefoot pressure, plantar force percentages, contact area, and maximal force. Dynamic analysis revealed decreased plantar pressure in the phalanx and medial forefoot bilaterally, with additional reductions in the lateral forefoot and hindfoot on the left side ( P < 0.05). Total plantar contact area during gait was also reduced. UCBL orthosis use results in measurable functional changes in plantar pressure distribution in children with flexible pes planus. Pedobarographic evaluation may serve as a useful tool for monitoring orthotic effectiveness in pediatric foot arch disorders.","PeriodicalId":50092,"journal":{"name":"Journal of Pediatric Orthopaedics-Part B","volume":" ","pages":"457-463"},"PeriodicalIF":0.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148018622","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}
