Variables influencing radiological fracture healing in children with femoral neck fractures treated surgically: A review of 177 cases.

Purpose: This study aimed: (1) to determine the probability of and the amount of time needed to achieve fracture healing in children with displaced femoral neck fractures (FNFs) treated surgically; and (2) to determine which factors can affect both the probability of and the amount of time needed to achieve radiological fracture healing in those patients.

Hypothesis: Pediatric FNFs require longer time to achieve union than previously reported.

Methods: We retrospectively reviewed the data of 177 children (mean age 10.

Comparison of two methods in the treatment of congenital pseudarthrosis of clavicle: multicenter experience.

Background: Congenital pseudoarthrosis of the clavicle (CPC) is an uncommon entity. Owing to its scarce presentation, treatment of this disorder has not been well established. This study aimed (1) to compare surgical treatment methods that included excision of pseudoarthrosis and iliac crest bone graft and fixate with either the elastic stable intramedullary nail (ESIN) or K-wires or plate and screws, and (2) to assess the clinical outcomes of two different surgical methods.

Management strategies of pediatric ipsilateral olecranon with associated radial neck fractures based on multicenter experience.

Background: The ipsilateral olecranon with associated radial neck fractures does not include in the Bado classification of Monteggia fractures and equivalent lesions. The primary aims of this retrospective multicenter study were to characterize this type of injury and, noting its unique properties, evaluate the results of the treatment, determine the prognostic factors that influence the radiological and clinical outcome, and also give treatment strategies.

Methods: Between July 2011 and July 2016, forearm fracture patient charts were retrospectively reviewed from seven pediatric trauma centers.

The neurofibromatosis type I gene promotes autophagy via mTORC1 signalling pathway to enhance new bone formation after fracture.

Bone fracture is one of the most common injuries. Despite the high regenerative capacity of bones, failure of healing still occurs to near 10% of the patients. Herein, we aim to investigate the modulatory role of neurofibromatosis type I gene (NF1) to osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) and new bone formation after fracture in a rat model.

Radiographic outcome of children older than twenty-four months with developmental dysplasia of the hip treated by closed reduction and spica cast immobilization in human position: a review of fifty-one hips.

Purpose: This study aimed to investigate the radiographic outcomes, rate of redislocation, and avascular necrosis of proximal femoral epiphysis (AVN) in patients aged 24 to 36 months with developmental dysplasia of the hip (DDH) treated by closed reduction (CR) and spica cast immobilization in human position.

Material And Methods: We reviewed the medical records of 39 patients (51 hips) aged 24 to 36 months with DDH treated by CR and spica cast immobilization in human position. The Tönnis grade, rate of redislocation and AVN, acetabular index (AI), centre-edge angle (CEA), and Severin radiographic grade were evaluated on plain radiographs.

Traction does not decrease failure of reduction and femoral head avascular necrosis in patients aged 6-24 months with developmental dysplasia of the hip treated by closed reduction: a review of 385 patients and meta-analysis.

This study aimed to investigate the effects of preliminary traction on the rate of failure of reduction and the incidence of femoral head avascular necrosis (AVN) in patients with late-detected developmental dysplasia of the hip treated by closed reduction. A total of 385 patients (440 hips) treated by closed reduction satisfied the inclusion criteria. Patients were divided in two groups according to treatment modality: a traction group (276 patients) and a no-traction group (109 patients).
