Blount’s disease: features of manifestation, diagnosis, and treatment methods

Understanding the essence of Blount’s disease

Blount’s disease, also known as childhood growth anomaly, is a dystrophic disorder of the growth of long tubular bones, primarily observed in children and adolescents. This pathology is characterized by slow but progressive deformity of the lower limbs, resulting in the development of pronounced knee joint deformity and external rotation of the tibia. The main clinical manifestations of Blount’s disease include characteristic deformity of the lower limbs with an increasingly deep inward concave angle of the knee, limited mobility in the knee joints, and an observable walking pattern when walking.

Understanding the essence of Blount’s disease requires a comprehensive approach, including detailed clinical examination, radiological diagnosis, and the use of modern treatment methods. Effective management of this disorder includes conservative methods (for example, physiotherapy, orthopedic correction) and, if necessary, surgical intervention to correct limb deformities. The primary goal of treating Blount’s disease is not only to improve the aesthetic appearance of the lower limbs but also to prevent the progression of deformities and ensure optimal functional status of the patient’s musculoskeletal system.

Factors contributing to the development of Blount’s disease

Blount’s disease, characterized by lower limb deformation, usually manifests in children and adolescents. The main factors contributing to the development of this condition may include genetic predispositions, growth disturbances of the fibula and hip joint, as well as mechanical stress on growth areas of the bones. Other possible causes may include joint hypermobility, obesity, and uneven distribution of load on the lower limbs during growth, which can lead to the emergence of this pathological condition. It is important to identify the key factors that contribute to the formation of Blount’s disease to develop an optimal strategy for treatment and prevention of this condition.

  • Genetic predisposition: the presence of certain genetic factors may increase the risk of developing Blount’s disease.
  • Disorders in the growth of the fibular cartilage: deformations and discrepancies in the growth of cartilages may contribute to the formation of the disease.
  • Mechanical impact: uneven distribution of loads on the lower limbs can cause deformations and developmental disorders.
  • Joint hypermobility: excessive joint mobility may negatively affect the development of bone tissue.
  • Obesity: excess weight creates additional stress on bones and joints, which may worsen the situation in Blount’s disease.

The main signs and manifestations of Blount’s disease

Blount’s disease is characterized by deformities of the lower limbs, such as bowing of the shin, divergent growth-related plastic changes, and other anomalies caused by disruptions in the normal growth and development of bones. Signs of this disease may include shortening of the shin, asymmetry of leg lengths, as well as curvature of the bones in the lower limbs. Other symptoms include knee deformation to the side, discrepancies in the size of the femur, and painful reduction in the distance of the homolateral wrist to the flexor surface of the pelvic bone, which requires careful clinical examination and accurate diagnosis.

  • Deformations of the lower limbs: Blount’s disease manifests as bowing of the shin, asymmetry in leg length, and bone curvature.
  • Shortening of the shin: A characteristic symptom is the reduction in shin length compared to the healthy limb.
  • Curvature of the knee: There may be a curvature of the knee to the side, which is one of the signs of Blount’s disease.
  • Mismatch in bone sizes: Patients with Blount’s disease may experience discrepancies in the sizes of the thigh bone.
  • Painful decrease in wrist distance: This symptom requires careful evaluation and may assist in the diagnosis of Blount’s disease.

The perspective of medical specialists on the treatment of Blount’s disease

The opinion of medical specialists regarding the treatment of Blount’s disease tends toward a comprehensive approach that includes conservative methods such as physical therapy, bracing, and rehabilitation activities, as well as surgical intervention in cases of significant deformities or complications.

Experts emphasize the importance of timely diagnosis and an individual approach to each patient, taking into account the degree of disease progression, age, and overall health status. They recommend regular monitoring and consultations with specialists for effective control of the disease’s course and the selection of an optimal treatment plan aimed at improving the patient’s quality of life.

Methods of diagnosing Blount’s disease

For accurate diagnosis of Blount’s disease, various examination methods are often used, including clinical examination and radiography of the lower limbs to identify characteristic deformities and deviations from the norm. The clinical examination includes analysis of the patient’s gait, standing checks, measurement of angles and lengths of projections, as well as assessment of symptoms of functional disorders. Radiological examination helps determine the degree of bone deformation, possible growth disturbances, and associated joint changes, allowing for an accurate diagnosis and selection of the optimal treatment plan for a patient with Blount’s disease.

  • Clinical examination: The doctor analyzes gait, standing, measures angles and lengths of processes, as well as assesses functional symptoms.
  • X-ray examination: X-ray investigation is used to visualize the degree of bone deformation, possible growth disturbances, and changes in joints.
  • Computed tomography (CT): CT scanning can provide additional information about structural changes in bones and joints.
  • Magnetic resonance imaging (MRI): MRI can help see detailed images of tissues and structures, which is useful in assessing the condition of joints and surrounding tissues.
  • Densitometry: The method of measuring bone density helps assess their condition and the risk of osteoporosis, which is important for planning treatment measures for Blount’s disease.

Methods of treatment for Blount’s disease

The treatment of Blount’s disease depends on the severity of the case, the age of the patient, and the presence of complications. In cases of moderate and severe disease, surgical intervention may be required to correct bone deformities and adjust growth. Surgical methods such as osteotomies or intramedullary distraction devices may be used to restore the normal anatomy of the limbs and correct deformities, which helps improve the patient’s quality of life and prevent subsequent complications. Additionally, physiotherapy procedures may be included in the treatment plan to strengthen muscles and joints, as well as rehabilitation activities aimed at restoring the functionality of the lower extremities after surgery.
