This retrospective study included all nonambulatory CP patients [Gross Motor Function Classification System (GMFCS) IV-V] who underwent greater trochanter-sparing PFR as the standard hip salvage procedure at a single tertiary center. Nineteen patients were initially identified; 2 were deceased, and 3 were lost to follow-up, resulting in 14 patients (17 hips) with complete data. Preoperative assessment involved GMFCS level, Reimer's Migration Index, and Care and Comfort Caregiver Questionnaire (CareQ) scores. Postoperative outcomes included radiographic migration, hip range of motion, presence of heterotopic ossification, complications, and CareQ-based functional improvement. Statistical analyses evaluated changes in functional and radiographic outcomes, using nonparametric methods appropriate for the small sample size. Fourteen patients (17 hips) were included, with a mean age of 19.4 ± 9.2 years. Postoperative femoral migration averaged 20.0 ± 12.2 mm, and heterotopic ossification occurred in most hips (type II 58.8%).

Patients with idiopathic genu valgum treated with tension-band plates between January 2013 and April 2023 were retrospectively analyzed. Demographic data and radiological measurements, specifically mechanical axis deviation, were evaluated at three time points: at the time of surgery, at the time of implant removal, and 1 year after implant removal. To evaluate factors associated with the risk of rebound, a mixed-effects logistic regression model was used. A total of 46 patients (91 limbs) were analyzed. The mean age at the time of surgery was 12.3 ± 1.28 years. The mean follow-up period after implant removal was 28.3 ± 19.4 months. The mean time to achieve mechanical axis correction was 10 months. The incidence of rebound was 67% [95% confidence interval (CI): 51-80].

The findings of this study highlight that a significant proportion of pediatric patients with idiopathic genu valgum treated with guided growth experienced rebound after implant removal.

A retrospective review was performed on patients with AMC with failed prior DFEO who underwent revision surgery between 2021 and 2023. Six patients, ten knees, were identified. Radiographic and clinical measurements were compared using paired t tests. The primary outcome was correction of knee flexion contracture. Secondary outcomes included arc of motion and ambulation.

This matched-pair comparative study included children who underwent MCO ≥12 months previously and healthy controls matched 1 : 1 by sex, age, and BMI. Dynamic plantar pressure was recorded. Outcomes included arch index, regional plantar impulse, relative loading index across hindfoot/midfoot/forefoot, foot axis angle, and plantar phase-times normalized to stance. Mixed-effects multivariable linear regression was utilized, adjusted for age, sex, and BMI. Twenty-one children with flexible flatfoot were matched to 21 controls (38 feet per group).

Midfoot impulses and regional foot loading were comparable between groups, whereas the flexible flatfoot group showed a more externally rotated foot axis angle. Total stance time did not differ, but the forefoot push-off phase (FFPOP) was 7.49% shorter in the flexible flatfoot group. A higher BMI was independently associated with a higher arch index and midfoot impulse.

In CTEV, the talus was plantarflexed with a short medially deviated neck, and the posterior facet was flat instead of the normal quadrilateral shape, with a less convex tibiotalar articular surface. Calcaneus in CTEV was slightly smaller, displaced into varus, equinus, and internal rotation, and the posterior articular surface was triangular and transversely flat. Angular measurements (α, β, γ, δ) of the talus were increased while the λ angle of the calcaneus was decreased to almost half. All morphometric measurements were statistically significant ( P values 0.001 by Mann-Whitney U test). The soft tissues (muscle and tendon) were shorter in length compared to normal.

A retrospective analysis of patients aged less than 18 at a single institution who received TBP between 2005 and 2017 for valgus angular deformities was conducted. Inclusion criteria were patients with complete data and MPS or idiopathic etiology. Femoral and tibial deformities were evaluated independently. Postsurgical X-rays were reported at 6-month intervals. Statistical significance was determined by Mann-Whitney and χ2 tests. Twenty-nine patients were included: Hurler syndrome (8), Morquio syndrome (1), and idiopathic (20). Femoral TBP corrections at 1 year were 4.9° (MPS) and 11.2° (idiopathic); total degrees of correction were 7.3° (MPS) and 8.9° (idiopathic). Tibial TBP corrections at 1 year were 5.8° (MPS) and 5.4° (idiopathic); total degrees of correction were 9.1° (MPS) and 6.0° (idiopathic). The average correction rates for femoral TBPs were 4.3°/year (MPS) and 7.3°/year (idiopathic), and tibial TBPs were 4.5°/year (MPS) and 4.6°/year (idiopathic). Full correction was achieved in four of nine (44.4%) MPS patients and 14 of 20 (70%) idiopathic patients, as well as 9 of 22 (40.9%) MPS limbs and 20 of 38 (52.6%) idiopathic limbs. There were no statistically significant differences between groups or by gender. MPS patients with femoral and tibial TBPs experienced comparable correction rates to idiopathic patients, although idiopathic patients corrected slightly faster, consistent with prior literature. This demonstrates that TBP is an effective growth modulation technique for MPS patients despite morphological differences.","PeriodicalId":50092,"journal":{"name":"Journal of Pediatric Orthopaedics-Part B","volume":" ","pages":"429-435"},"PeriodicalIF":0.9,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148152016","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}
