Purpose:
To conduct a visualization analysis of macrodactyly research from 2005 to 2024, providing a comprehensive overview of research trends, key contributors, and emerging topics.
Methods:
A visual analysis of macrodactyly related publications from 2005 to 2024 was conducted using the Web of Science Core Collection database. Publication trends, country and institutional contributions, author collaboration networks, and keyword co-occurrences were analyzed. Statistical analysis and visualization were performed using Microsoft Excel, R, VOSviewer, and CiteSpace.
Results:
One hundred and fifty-three publications were included. Annual publication trends showed fluctuations but an overall growth in interest over time, with notable growth from 2011 to 2014 peaking at 15 publications in 2014. The United States led with 128 publications, followed by China (60), Italy (40), Japan (36), and Turkey (27), with prominent institutions such as Mayo Clinic and Harvard University playing pivotal roles. Key authors like Dr. Marybeth Ezaki, working with the team at Texas Scottish Rite Hospital for Children, made substantial contributions to establishing diagnostic frameworks. Most importantly, keyword analysis revealed a fundamental shift in research focus from clinical and surgical themes (represented by keywords such as "foot," "hand," and "osteotomy" in early periods) to molecular and genetic investigations (characterized by "PIK3CA," "activating mutations," and "overgrowth" in recent years). The strongest citation burst was "overgrowth" (2016-2020), followed by genetic-related terms, with "activating mutations" representing the most recent trend (2020-2024), indicating increasing emphasis on PIK3CA mutations as the current research hotspot.
Conclusion:
This study highlights the evolution of macrodactyly research and reveals fluctuating publication trends and substantial contributions from key countries, authors, and institutions. The transition from clinical and surgical approaches to molecular and genetic investigations underscores advancements in the field. Future research should prioritize integrating genetic findings with clinical applications and advancing diagnostics and treatment strategies.

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...

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
