Summary
Patients with lower limb discrepancy treated with the Ilizarov method showed significant bone mineral density differences between limbs. This highlights the importance of densitometric monitoring during bone regeneration.
Area of Science:
- Orthopedics
- Radiology
- Pediatrics
Background:
- Lower limb discrepancy (anisomelia) is common, with shortening occurring in 90% of cases.
- This study focuses on densitometric testing in patients treated for limb length inequality.
Purpose of the Study:
- To evaluate bone mineral density (BMD) in patients with lower limb discrepancy treated using the Ilizarov technique.
- To compare BMD between the shortened limb and the contralateral limb.
Main Methods:
- Densitometric tests were performed on 57 patients (31 girls, 26 boys) using a DPX apparatus.
- BMD was measured in the shortened limb segment and compared to the opposite limb, avoiding the knee joint area.
- The Ilizarov technique was used to lengthen 33 femurs and 24 tibias with an average discrepancy of 45 mm.
Main Results:
- A BMD difference was observed in 82.5% of patients, with an average difference of 16.5%.
- Shorter femurs showed a higher BMD difference (19.1%) compared to shorter tibias (14%).
- Greater demineralization was noted in girls (23.5%) than in boys (20%).
Conclusions:
- Densitometric monitoring is crucial for evaluating bone regeneration during Ilizarov treatment for lower limb discrepancy.
- Findings suggest potential differences in bone healing or adaptation based on limb and sex.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:17Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...

01:18Classification of Bones
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
