Insights

Deferiprone, an iron chelator for thalassemia, can cause joint issues. This study identified unique bone changes in children

Area of Science:

  • Pediatric Hematology
  • Pediatric Radiology
  • Skeletal Dysplasias

Background:

  • Thalassemia requires regular blood transfusions and iron chelation therapy.
  • Deferiprone is an oral iron chelator used in thalassemia treatment.
  • Deferiprone-induced arthropathy has known clinical and radiographic features, but long-term effects are unclear.

Purpose of the Study:

  • To describe the long-term skeletal effects of deferiprone-related arthropathy in children with thalassemia major.
  • To identify unique radiographic changes associated with deferiprone exposure.

Main Methods:

  • Retrospective analysis of wrist and hand radiographs from 40 children with thalassemia.
  • Evaluation of unique radiographic changes in 13 children with a history of deferiprone-related arthropathy.
  • Subsequent radiographic examination of knee joints in affected children.

Main Results:

  • Wrist radiographs revealed ulnar metaphyseal lucency and thinning, small ulnar epiphysis, and impaired physeal growth.
  • Knee radiographs demonstrated subchondral flattening of femoral and tibial condyles with irregular articular margins.
  • These findings suggest a pattern of bony dysplasia and growth disturbance.

Conclusions:

  • Bony dysplasia, deformation, and impaired growth of ulnar epiphyses, metaphyses, and physes may indicate deferiprone-related arthropathy in pediatric thalassemia patients.
  • These radiographic findings highlight potential long-term skeletal consequences of deferiprone treatment.
  • Further research is needed to fully understand the long-term skeletal impact.

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
Changes in the Appendicular Skeleton with Age01:09

Changes 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...
Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
