Traditional diagnostic tools such as anteroposterior pelvic radiographs are limited in evaluating the three-dimensional morphology of the acetabulum, especially in pediatric populations. This study introduces novel measurement parameters that include both angular and dimensional metrics for a comprehensive assessment of acetabular morphology. It also compares these parameters between normal and dysplastic hips in pediatric population. Computed tomography scans of 35 children with unilateral DDH, aged between four and 48 months, were analyzed, comparing dysplastic and normal hips. Parameters measured included anterior and posterior acetabular indexes and lengths, anterior and posterior coverage angles, lengths, and posterior coverage area, dome length and dome coverage. Statistical analyses evaluated differences between groups. Dysplastic hips exhibited higher anterior and posterior acetabular index values and reduced anterior and posterior acetabular lengths, reflecting global elongation and shallowness. Anterior coverage angle was significantly greater, while posterior coverage angle and posterior coverage parameters were reduced, highlighting posterior wall deficiencies. Dome coverage was also significantly decreased. All measurements showed good to excellent interobserver and intraobserver reliability (0.68-0.94 and 0.76-0.92, respectively). Our findings suggest that DDH involves global acetabular deficiencies, including posterior insufficiency, challenging the traditional focus on anterolateral deficiencies. The introduced parameters provide a reproducible method for evaluating pediatric acetabular morphology, offering valuable insights for diagnosis and treatment planning. Future studies should validate these findings and explore MRI for enhanced diagnostic accuracy.","PeriodicalId":50092,"journal":{"name":"Journal of Pediatric Orthopaedics-Part B","volume":" ","pages":"359-367"},"PeriodicalIF":0.9,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147700581","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}

Secondary outcomes included the occurrence of complications, especially those requiring reoperation. Children were divided into two groups based on the location of the distal nail. In group A, the nail ends were buried within the distal femoral metaphyseal cortex. In group B, the ends extended just beyond the cortex. FIN survival was defined as retention without the need for removal or replacement. Twenty children met the inclusion criteria: nine females (45%) and 11 males (55%). Mean age was 10.4 ± 3.7 years.

A retrospective analysis was conducted on 302 DDH children (347 hips) who underwent CR-SCI at our department from 1 January 2003 to 31 December 2015. Among them, 42 cases (50 hips) were male, and 260 cases (297 hips) were female. The acetabular index, center edge angle (CEA), and avascular necrosis (AVN) of the femoral head were measured and evaluated on anteroposterior pelvic radiographs. The Severin classification was recorded at the final follow-up. Preoperative analysis of acetabular index revealed poorer hip development in females than in males ( P = 0.003). However, last follow-up acetabular index, acetabular index improvement, and last follow-up CEA were comparable for both sexes ( P > 0.05). There were no statistically significant differences in postoperative re-dislocation rates, reoperation rates, or Severin classification at the final follow-up ( P > 0.05). However, significant differences were observed in the incidence of AVN ( P = 0.025) and AVN grading ( P = 0.046) at the final follow-up. Further univariate analysis showed that gender significantly influenced AVN ( P = 0.025). Multivariate analysis revealed that gender ( P = 0.005) and adductor tenotomy ( P = 0.028) were influencing factors for AVN. Gender is an influencing factor for AVN after CR-SCI for DDH, with male children having a higher probability of developing AVN postoperatively, indicating poorer outcomes despite no significant differences in postoperative imaging and functional outcomes between genders.

The triple pelvic osteotomy (TPO) corrects acetabular orientation, while acetabuloplasty improves containment, but they are insufficient on their own for severe deformities where both coverage and depth are compromised; combining both procedures allows simultaneous correction of orientation and morphology. In this study, the feasibility and safety of this combined approach were evaluated in adolescents with steep acetabula and dysplasia. Between 2020 and 2023, patients with adolescent neuromuscular hip dysplasia underwent combined TPO-Dega acetabuloplasty. The radiographic outcomes included Sharp's angle, acetabular depth-width ratio, center-edge angle, migration index, and neck-shaft angle. The surgical time, blood loss, and complications were recorded. Five patients with cerebral palsy (mean age: 14.4, 11.5-16 years) underwent combined TPO-acetabuloplasty. The mean follow-up was 15.6 (12-24) months, mean surgical time was 294 (225-360) min, and mean blood loss was 469 (375-600) ml.

The objective is to describe a 3D imaging-guided technique for excision of partial physeal bars and to report the results of a series of patients who have undergone this procedure. This is a retrospective chart review of five patients treated at a level 1 pediatric tertiary care center by a fellowship-trained pediatric orthopedic surgeon. Inclusion criteria were: (1) Pediatric patients aged 2-18 diagnosed with a partial physeal arrest with resulting deformity, (2) treatment with partial physeal excision using 3D imaging guidance between January 2008 and December 2022, and (3) appropriate radiographic follow-up of at least 6 months. Preoperative 3D imaging demonstrated physeal bar size and location for each patient and was utilized for operative planning. Descriptive statistics were used. The use of 3D imaging guidance for physeal bar excision resulted in improved radiographic angular deformities and LLD. Our cohort had an average physeal bar size of 6.7 ± 3.6% of the physis with no complications reported.

There was a significant difference in the number of operations under general anesthesia (2 ± 0 in group T-B, 1.1 ± 0.3 in group T-NB, 1 ± 0 in group P). Delayed union was observed in group P (0/24 in groups T-B and T-NB, and 6/15 in group P). Surgical site infection requiring surgical debridement occurred in two patients in the group T-NB. The three surgical techniques showed equivalent clinical results. The buried tension band wiring technique could be superior among the three techniques because it showed fewer complications, including delayed union and infection.","PeriodicalId":50092,"journal":{"name":"Journal of Pediatric Orthopaedics-Part B","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148347231","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}
