Purpose: The purpose of this study was to define how different force environments by neuromuscular diagnosis (hypertonic versus hypotonic) impact the growth and morphology of the proximal femoral and acetabular regions relative to typically developing children.
Methods: Children with cerebral palsy and spinal muscular atrophy were compared with typically developing children aged 6 months to 11 years. Routine pelvic radiographs were evaluated using measures of hip geometry for the proximal femur and acetabulum.
Introduction: The neck-shaft angle and head-shaft angle in children with varying levels of neurological disability were evaluated to define change over different ages.
Methods: Children aged 1-12 years with spastic cerebral palsy, spinal muscular atrophy types 1 and 2, or typical development were reviewed to evaluate the neck-shaft angle and head-shaft angle. Patients were divided into five groups: Gross Motor Function Classification System levels I and II, Gross Motor Function Classification System level III, Gross Motor Function Classification System levels IV and V, spinal muscular atrophy types 1 and 2, and typical development.
Article Synopsis
- The surgical management of scoliosis in patients with osteogenesis imperfecta (OI) is complicated by factors such as rigid spinal curves, short stature, and fragile bones, prompting a study on various treatment methods.
- A retrospective review of 30 OI patients (average age 14.1 years) who underwent posterior spinal fusion revealed significant improvements in major curve correction and other spinal parameters after a minimum follow-up of 2 years.
- Complications were minimal, with only two patients experiencing issues like proximal junctional kyphosis, indicating the approach's effectiveness and safety in addressing severe scoliosis in OI patients.
Purpose: This study aimed to clarify the differences in spine and total body height growth and curve progression between Sanders maturation stage (SMS) 7A and 7B in patients with adolescent idiopathic scoliosis (AIS).
Methods: This retrospective case-control study involving patients with AIS at SMS 7 evaluated the differential gains in the spine (T1-S1) and total body height and curve progression between SMS 7A and 7B. A validated formula was used to calculate the corrected height, accounting for height loss due to scoliosis.
Cerebral palsy (CP) is a heterogeneous group of disorders with different clinical types and underlying genetic variants. Children with CP are at risk for fragility fractures secondary to low bone mineral density, and although bisphosphonates are prescribed for the treatment of children with bone fragility, there is limited information on long-term bone impact and safety. Children with CP usually present overtubulated bones, and the thickening of cortical bone by pamidronate treatment can potentially further narrow the medullary canal.

Methods: A single-center, retrospective review identified 62 children (32 male, 30 female) with achondroplasia.
Objective: To evaluate the postoperative results of patients with supination-external rotation ankle fractures who underwent syndesmotic screw (SS) removal.
Methods: Retrospective cohort study assessing the late postoperative results of 35 patients operated from January 2013 to June 2015. Patients undergoing treatment of rupture of the distal tibiofibular syndesmosis with SS fixation and who did not have any concomitant surgical injuries in sites other than the ankle were included.
Objective: To evaluate the clinical results of surgical treatment of intraarticular fractures of the calcaneus, comparing the use of calcaneal plate and flat plate.
Methods: This was a retrospective study assessing the postoperative results of 25 patients between 2013 and 2015. Patients undergoing surgical treatment of intraarticular fractures of the calcaneus without concomitant surgical lesions were included.
