This study aimed to investigate three-dimensional computed tomography (3D CT) talar morphology in children with idiopathic and neuromuscular pes planovalgus. Eleven children [nine boys, two girls; mean (SD) age: 10.5 (2.8) years] with idiopathic pes planovalgus and 15 children [three boys, 12 girls; mean (SD) age: 10.8 (3.4) years] with neuromuscular pes planovalgus were included. All patients underwent 3D CT and weight-bearing anteroposterior, lateral, and axial radiography. Demographic data and talar 3D CT and radiographic measurements were compared between both groups. The correlation between the measurements was also analyzed. The neuromuscular group showed significantly more severe deformity than the idiopathic group in the radiographic and 3D sagittal talus measurements. The 3D coronal talus measurement showed a significant negative correlation with the axial hindfoot alignment in the idiopathic group while the 3D transverse talus measurement was significantly correlated with the lateral talocalcaneal angle in the neuromuscular group. 3D intraosseous alignment of the talus is correlated with pes planus deformity. Longitudinal and biomechanical studies including a control group are necessary to elucidate the role of 3D talar morphology on a dynamic imbalance in pes planovalgus.","PeriodicalId":16709,"journal":{"name":"Journal of Pediatric Orthopaedics B","volume":"244 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74493382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports results and complications in a series of walking children affected by neglected congenital vertical talus treated by one-stage release through a double surgical approach in a hospital sited in the Tanzanian rural outback. Between 2009 and 2014, nine consecutive congenital vertical talus were observed in five patients (three males and two females) aged between 2 and 4 years. In two children, the deformity was idiopathic, in two it was associated to distal arthrogryposis and in one to Larsen syndrome. The surgical procedure was performed through a posteromedial and a lateral incision and included extensive soft tissue release and reduction of talo-navicular and subtalar joint, pinned with percutaneous Kirschner wires. The talar axis-first metatarsal base angle (TAMBA) was measured preoperatively and at follow-up. Results were summarized using the Adelaar score and the PODCI (Pediatric Outcomes Data Collection Instrument) questionnaire. The mean follow-up was 2.6 years (2-4). No major intraoperative complications were observed. The TAMBA passed from 74.4º (range 68-82º) to 20.2º (range 18-24º). No talar osteonecrosis was observed. The results were excellent in three cases, good in five cases and fair in one (Adelaar score). The mean postoperative PODCI score was 48 (range 38-60). None of the patients underwent further surgery. In case of neglected congenital vertical talus and limited health resources, this surgical technique has proved to be a viable option, providing satisfactory results, with low rate of surgical and postsurgical complications.","PeriodicalId":16709,"journal":{"name":"Journal of Pediatric Orthopaedics B","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75344265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it has not yet been determined whether a physeal biopsy procedure affects angular deformity. We employed a rabbit model to collect biopsies of the distal femoral and proximal tibial physes on anesthetized, 8-week old New Zealand rabbits. The contralateral limb served as a control. At 8 (n = 5) and 16 (n = 5) weeks postbiopsy, animals were euthanized. Micro-computed tomography (CT) was employed to estimate percentage of the physis biopsied and assess structural abnormalities resulting from biopsy. Bone samples were embedded in polymethylmethacrylate and analyzed. The percentage of physis sampled was ≤1.5% of the total femoral physis while all but one of the tibiae had ≤2.3% removed. There were no iatrogenic clinical or radiographic deformities (frontal or sagittal). Micro-CT and histological analysis suggested that physeal defects had signs of healing that did not lead to subsequent angular deviation. A defect caused by physeal biopsy may not lead to angular deformity. Long-term data could help determine the safety and efficacy of collecting biopsies for histological analyses. Advanced imaging may demonstrate a detailed picture of anatomic or structural alteration of a given physis, but provides no functional information. The diagnostic and therapeutic information that could be gleaned from one or more serial biopsy samples could be invaluable in decision making and clinical management (e.g. skeletal dysplasias and metabolic conditions), so long as subsequent deformity is not a future possibility.","PeriodicalId":16709,"journal":{"name":"Journal of Pediatric Orthopaedics B","volume":"5 6","pages":"93 - 100"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91485177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Posterior spine surgery is common practice for adolescent idiopathic scoliosis (AIS). Common, less severe surgical risks include pressure ulcers; while rare, more severe pressure complications include rhabdomyolysis and compartment syndrome. In patients with HS, a familial hemolytic disorder with altered red cell deformability, it is unknown if their red cell disorder is an additional risk factor for pressure-related surgical injuries. Two patients with HS, an 18-year-old male and a 17-year-old female, were both post-splenectomy and underwent revision posterior spinal fusion and instrumentation for progressive AIS. Surgery lasted 9 hours and 7 hours respectively, with no intraoperative complications other than prolonged surgical time due to revision nature of the deformities. Thigh redness and swelling was noted in both patients directly deep to the thigh pads. Thigh myonecrosis was diagnosed with eventual recovery in both cases. Patients with HS may be at inherent more risk of pressure complications during posterior spine surgery. We propose that thigh myonecrosis occurs with decreased perfusion and hemolysis from HS erythrocytes’ inherent fragility, decreased deformability within capillaries, and prolonged microvasculature compression from positioning, causing poor microvascular perfusion, tissue ischemia, and reperfusion injury.

Patients with a diagnosis of TEV deformity, in-toeing gait secondary to residual internal tibial torsion corrected with tibial rotation osteotomy (TRO) and complete preoperative and postoperative motion analysis studies obtained approximately 1 year apart, were included in the study. Nineteen children (19 left extremities) with a TRO at a mean age of 8.2 years met inclusion criteria. Clinical examination showed improvement in tibial torsion assessment by measure of the thigh foot axis and transmalleolar axis. Kinematically, an abnormal internal FPA was present in all cases preoperatively, was corrected to normal in 12 (63%), remained internal in 5 (26%), and was abnormally external in 2 (11%). External hip rotation was identified in 13 (68%) cases preoperatively. Hip rotation was normalized postoperatively in 7 (54%), and was unchanged in the remaining 6 (46%). TRO provides effective correction of excessive internal tibial torsion, resolution of kinematic internal knee rotation, and normalization of the internal foot progression angle in the majority of patients with TEV deformity.

The purpose of this study was to determine radiographic and clinical features likely to lead to open reduction before flexible intramedullary nailing. Record review identified 158 femoral shaft fractures treated with flexible intramedullary nailing. In addition to patient demographics and mechanism of injury, data obtained included surgeon name, estimated blood loss, type of reduction, type and diameter of nail, type of operating table, the use of percutaneous reduction techniques or supplemental casting, time to and duration of surgery, total time in operating room, and time to union. Fracture ratios were calculated based on established radiographic protocol. Of 158 fractures, 141 were treated with closed reduction and 17 with open reduction. The anteroposterior fracture index (1.3 ± 0.4, P = 0.0007), surgeon (P = 0.002), and flattop operating table (0.05) were associated with open reduction. Smaller lateral diameter of bone at the fracture site, transverse fracture, and surgeon were all found to be independent risk factors for open reduction; patient characteristics, including age, sex, and BMI, did not seem to influence the choice of open reduction. Fractures with a lower fracture index or pattern resembling a transverse fracture rather than oblique or spiral had an increased risk of converting to an open reduction. Surgeon preference and use of flattop tables also had a significant influence on how the fracture was treated.","PeriodicalId":16709,"journal":{"name":"Journal of Pediatric Orthopaedics B","volume":"44 1","pages":"472 - 477"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81325637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A distinction can be made in an early and late onset type. The disease seems to have a predisposition for certain descends. Since the first publication of Blount’s disease, different hypotheses on the aetiology are proposed but no consensus exists. The objective of this study is to provide an overview of the available hypotheses on the aetiology of Blount’s disease since its first description and assessment of the available level of evidence, the quality of evidence and the occurrence of bias supporting these individual hypotheses. A systematic search according to the PRISMA statement was conducted using PubMed, MEDLINE, EMBASE and the Cochrane Library using a broad combination of terminology to ascertain a complete selection. Proper MESH search criteria were formulated and the bibliographic search was limited to English and Dutch language articles. Articles with no mention of aetiology or a disease related to Blount’s were excluded. Level of evidence and types of bias were assessed. Thirty-two articles that discuss the aetiology of Blount’s disease were selected. A variety of hypotheses was postulated in these articles with most research in the field of increased mechanical pressure (obesity, early walking age) and race (descend). Blount’s disease most likely has a multifactorial origin with influence of genetic and racial predisposition, increased mechanical pressure on the growth plate as a consequence of obesity or early walking age and possibly also nutrition. However, the exact aetiology remains unclear, the probable explanation is that multifactorial factors are all contributing to the development of Blount’s disease. Histological research has shown that a disorganization of bone and cartilage structures on the medial side of the proximal tibial physis is present in patients with Blount’s disease. Based on the available evidence on the aetiology of Blount’s disease, we conclude that it is multifactorial. Most papers focus only on one hypotheses of Blount’s disease occurrence and all are characterized as low level of evidence. There seems to be a preference for certain descends. Further research on especially genetic predisposition is needed to provide more insight in this factor of Blount’s disease.","PeriodicalId":16709,"journal":{"name":"Journal of Pediatric Orthopaedics B","volume":"45 1","pages":"323 - 336"},"PeriodicalIF":0.0,"publicationDate":"2019-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81494533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
