X-rays for leg length measurement.. Unequal leg length in children is frequently first suspected by parents noticing a limp that appears to be getting worse. [3] The standard workup in children is a thorough physical examination, including observing the child while walking and running. [3]
For children with CPT, pathological fracture of the tibia eventually occurs, resulting in persistent nonunion of the fracture site. If left untreated, leg deformities, joint stiffness, leg-length discrepancy and pain will persist. [ 3 ]
Clinical feature: presents after the child has started walking but before six years of age. Usually associated with a painless hip due to mild abductor weakness and mild limb length discrepancy. If there is a bilateral involvement the child might have a waddling gait or trendelenburg gait with an increased lumbar lordosis.
Blount disease is a growth disorder of the shin bone which causes the lower leg to angle inward, resembling a bowleg. It can present in boys under 4-years in both legs, or in adolescents usually on one side. Causes are thought to be genetic and environmental, like obesity, African-American lineage, and early walkers. [4]
Congenital limb deformities are congenital musculoskeletal disorders which primarily affect the upper and lower limbs. An example is polydactyly , where a foot or hand has more than 5 digits. Clubfoot , one of the most common congenital deformities of the lower limbs, occurs approximately 1 in 1000 births.
Some children with knee disarticulation use prosthetic legs to walk. Prosthetics for children without substantial hip and trunk control is usually abandoned in favor of faster and easier wheelchair mobility as the child's weight and age increase. Children may walk on their hands and generally are able to climb and move about to accomplish ...
Mini-knemometry determines the lower leg length with an accuracy of less than 100 μm (0.1 mm). This enables substantiating growth within 24 hours. In an animal model, the technique was used to investigate the effects of steroids and growth hormone on short-term growth. [5] These studies were an important prerequisite for improving growth ...
Congenital clubfoot occurs in 1 to 4 of every 1,000 live births, making it one of the most common birth defects affecting the legs. [6] [3] [7] About 80% of cases occur in developing countries where there is limited access to care. [6] Clubfoot is more common in firstborn children and males.
