[Progress on research of Madelung's deformity]

Area of Science:

• Orthopedics
• Radiology
• Genetics

Background:

• Madelung deformity is a rare forearm and wrist condition resulting from growth disturbances in the distal radius and ulna epiphyses.
• Its incidence is linked to trauma, epiphyseal abnormalities, nutritional issues, and genetic factors.
• Early symptoms are often atypical, with wrist deformity and weakness becoming apparent later.

Purpose of the Study:

• To review the diagnostic challenges and current understanding of Madelung deformity.
• To highlight the role of advanced imaging in early detection.
• To discuss current treatment strategies and their limitations.

Main Methods:

• Review of existing literature on Madelung deformity.
• Analysis of diagnostic methods, including plain film and MRI.
• Classification of deformity based on radiographic measurements (distal ulnar inclination angle, palm angle).
• Evaluation of current surgical interventions.

Main Results:

• Plain radiography often lacks early diagnostic significance for Madelung deformity.
• Wrist joint MRI can reveal early soft tissue and skeletal abnormalities, aiding diagnosis.
• The deformity can be classified into types based on specific angles.
• Surgical interventions like ulna revision and distal radius osteotomy are used for severe cases.

Conclusions:

• Madelung deformity presents diagnostic challenges, particularly in its early stages.
• Magnetic resonance imaging (MRI) offers improved early diagnostic capabilities compared to plain films.
• Current surgical treatments, while effective, carry risks such as trauma and infection.
