Unequal leg length with a very small degree of difference can be common; small inequalities in leg length may affect 40%-50% of the human population. It has been estimated that at least 0.1% of the population have a difference greater than 20 mm (0.79 in).
If left untreated, leg deformities, joint stiffness, leg-length discrepancy and pain will persist. [3] Diagnosis is done clinically and through X-ray imaging, with numerous classifications based on the severity of bowing and presence of fracture or intraosseous lesion. [4] Pathogenesis of CPT remains unclear.
This results in the leg being shortened and the development of a limp. It may be congenital and is commonly caused by injury, such as a fracture. It can also occur when the bone tissue in the neck of the femur is softer than normal, causing it to bend under the weight of the body. This may either be congenital or the result of a bone disorder.
limb length discrepancy (evaluated by placing the child in a supine position with the hips and knees flexed [unequal knee heights might be noticed – the Galeazzi sign]), and; restricted hip abduction. Sometimes during an exam a "click" or more precisely "clunk" in the hip may be detected [24] (although not all clicks indicate hip dysplasia). [25]
Common complications that can arise include leg-length discrepancy, joint contracture, growth retardation, low bone mineral density, and macrophage activation syndrome. [6] Some causes or potential risk factors denoting a higher chance of developing childhood arthritis have been identified. [7]
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
In children with limb-length differences or scoliosis, physiotherapy can alleviate the problems caused by these symptoms. In more severe cases, surgery to lengthen limbs may be required. To prevent aggravating posture difficulties children with leg length differences may require a raise in their shoe. [citation needed]
The ICD-10 Clinical Modification (ICD-10-CM) is a set of diagnosis codes used in the United States of America. [1] It was developed by a component of the U.S. Department of Health and Human services, [ 2 ] as an adaption of the ICD-10 with authorization from the World Health Organization .
