Understanding Osteoporosis
Courtesy: Prof Nabil Ebraheim, University of Toledo, Ohio, USA Osteoporosis: Causes, Pathophysiology, and Clinical Impact Overview Osteoporosis is a common skeletal disorder characterized by: Decreased bone mass Deterioration of bone microarchitecture Reduced bone strength Leads to an increased risk of fractures Bone Strength Depends On Bone mineral density (BMD) Bone quality: Microarchitecture Bone turnover […]
Eosinophilic Granuloma
Courtesy: Prof Nabil Ebraheim, University of Toledo, Ohio, USA Overview Vertebra plana refers to complete or near-complete collapse of a vertebral body, resulting in a flattened appearance. Classically associated with eosinophilic granuloma Represents a manifestation of Langerhans Cell Histiocytosis (LCH) Important because it can mimic multiple serious conditions Definition Vertebra plana: Flattening of vertebral […]

Paget’s Disease Of The Spine
Courtesy: Prof Nabil Ebraheim, University of Toledo, Ohio, USA Paget Disease of the Spine & Differential Diagnosis of Vertebral Sclerosis Overview When evaluating lumbar spine X-rays, a vertebra may appear abnormally sclerotic (white). This finding requires careful differentiation between multiple conditions, as imaging alone may not be sufficient. Common Differential Diagnoses Paget disease of […]

Key Pathological Process Excessive osteoclastic bone resorption Followed by disorganized osteoblastic bone formation Resulting Bone Characteristics Structurally weak Hypervascular Deformed Leads to altered joint biomechanics and […]
Paget’s Disease
Courtesy: OI Foundation Paget Disease of Bone (Osteitis Deformans) Overview Paget disease of bone is a chronic disorder of bone remodeling, first described by Sir James Paget in 1876. Characterized by: Excessive osteoclastic bone resorption Followed by disorganized osteoblastic bone formation Result Enlarged bone Structural weakness Bone deformities Epidemiology Prevalence Previously: 3–4% of individuals […]
Ochronosis and Alkaptonuria
Courtesy: Dr Shivshankar Challa, MS, MRCS, Mch Introduction: Overview of Alkaptonuria Alkaptonuria is an extremely rare autosomal recessive metabolic disorder. It is caused by deficiency of the enzyme homogentisic acid dioxygenase. The condition affects approximately one in two hundred and fifty thousand to one in one million live births. Under normal metabolism, homogentisic acid is […]
