Summary
Rapidly destructive hip disease involves rapid joint space narrowing, exceeding 2 mm annually. This severe condition, distinct from common osteoarthritis, is treated with total hip replacement.
Area of Science:
- Orthopedics
- Rheumatology
- Radiology
Background:
- Rapidly destructive hip disease (RDHD) encompasses various rapid forms of arthritis and arthropathies.
- It includes rapidly destructive osteoarthritis (RDOA), first described in 1970.
- RDHD is characterized by accelerated joint space narrowing, distinguishing it from common osteoarthritis.
Purpose of the Study:
- To define and differentiate rapidly destructive hip disease from common osteoarthritis.
- To outline the diagnostic criteria and clinical presentation of RDHD.
- To identify risk factors and established treatment for RDHD.
Main Methods:
- Definition based on radiographic evidence of joint space narrowing.
- Comparison of disease progression rates between RDHD and common osteoarthritis.
- Clinical assessment of pain, disability, and range of motion.
Main Results:
- RDHD features joint space narrowing of ≥2 mm/year, significantly faster than common osteoarthritis (0–0.80 mm/year).
- Chondrolysis in RDHD leads to subchondral bone erosion.
- Painful disability is typically more severe in RDHD, though passive range of motion is often preserved longer.
Conclusions:
- Rapidly destructive hip disease is a distinct clinical entity with accelerated joint degeneration.
- Key risk factors include advanced age, excess weight, and excessive physical activity.
- Total hip replacement is the recommended treatment for this debilitating condition.

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...

01:16Bones 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...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
01:27Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
01:23Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
