High-Yield Summary PFFD is a rare congenital deficiency characterized by hypoplasia or aplasia of the proximal femur, resulting in limb length discrepancy and functional impairment. Surgical management hinges on classification systems that predict femoral stability and hip joint potential, primarily the Aitken and Paley classifications. Treatment goals focus on optimizing limb length, hip stability, and […]
High-Yield Summary Polydactyly and syndactyly require precise anatomical understanding to restore function and aesthetics while minimizing complications such as web creep and scar contracture. Surgical timing is critical: polydactyly repair is typically performed between 6-12 months, syndactyly repair ideally before 18 months to optimize digit growth and function. Classification systems guide surgical planning: Wassel for […]
High-Yield Summary Congenital pseudarthrosis of the tibia (CPT) is a rare, challenging pathology characterized by tibial dysplasia and nonunion, often associated with neurofibromatosis type 1 (NF1). Early diagnosis and classification guide management; the Crawford classification remains the most clinically relevant for surgical planning. Surgical treatment prioritizes biological stimulation of union, mechanical stability, and deformity correction, […]
High-Yield Summary The Meyerding classification grades spondylolisthesis severity by percentage of vertebral body slippage, guiding surgical urgency and technique in pediatric patients. Pediatric spondylolisthesis most commonly involves L5-S1, with progression risk linked to slip grade, skeletal maturity, and symptoms. Accurate radiographic assessment using lateral standing radiographs is essential; dynamic views help assess instability but do […]
High-Yield Summary Osgood-Schlatter Disease (OSD) and Sinding-Larsen-Johansson Syndrome (SLJS) are traction apophysitis conditions affecting the tibial tubercle and inferior patellar pole, respectively, primarily in adolescent athletes during growth spurts. Diagnosis hinges on clinical presentation combined with targeted imaging; plain radiographs suffice initially, with MRI reserved for atypical or refractory cases. Non-operative management is first-line, focusing […]
High-Yield Executive Summary Blount’s disease is a growth disorder of the proximal tibial physis causing progressive varus deformity, primarily affecting early walkers and characterized by mechanical axis deviation and medial tibial plateau depression. Early diagnosis and differentiation between infantile and adolescent forms are critical, as infantile Blount’s often requires surgical intervention, while adolescent Blount’s may […]
High-Yield Executive Summary Congenital limb deficiencies are broadly categorized into transverse (limb ends abruptly) and longitudinal (absence or hypoplasia along the limb axis) types, with classification guiding reconstructive options. Surgical decision-making hinges on functional potential, residual limb length, and joint presence; prosthetic candidacy is critical in transverse deficiencies, while reconstructive surgery is often feasible in […]
High-Yield Executive Summary Tarsal coalition is a congenital or developmental fusion of two or more tarsal bones, most commonly calcaneonavicular and talocalcaneal, leading to rigid flatfoot and pain in children/adolescents. Diagnosis hinges on clinical suspicion in a child with rigid flatfoot, peroneal spasticity, and hindfoot pain; CT and MRI are essential for defining coalition type […]
High-Yield Executive Summary Flexible flatfoot in children is often physiological and asymptomatic; treatment is indicated primarily for symptomatic cases with functional impairment or pain. Key clinical indicators for intervention include persistent pain, activity limitation, progressive deformity, and failure of conservative management after 6–12 months. Radiographic evaluation is adjunctive; weight-bearing AP and lateral foot radiographs help […]
The Different Types of Pediatric Spinal Deformities and Their Classifications The “High-Yield” Executive Summary Pediatric spinal deformities primarily include scoliosis, kyphosis, and lordosis, each with distinct pathoanatomic and biomechanical profiles influencing management. Classification systems such as the Lenke classification for adolescent idiopathic scoliosis (AIS) and the King-Moe system remain central to surgical decision-making. Early-onset scoliosis […]
