Developments in Congenital Scoliosis and Related Research from 1992 to 2021: A Thirty-Year Bibliometric Analysis

Many studies, mainly original articles and reviews, have been reported on congenital scoliosis (CS), but there is a lack of bibliometric analyses. This study aimed to systematically analyze the developments and focuses in CS and related research fields.

Data were retrieved from the Web of Science Core Collection database, and the top 100 most-cited studies were analyzed emphatically. The Web of Science Results Analysis and Citation Report was used to analyze different aspects of the literature. CiteSpace was used to analyze the cooperation network, reference co-citation, burst keywords, and burst citations.

The final analysis included 749 studies. CS and related research has been rapidly expanding. Several journals have published relevant studies and most-cited studies on this topic. Cooperation was noted among authors, institutions, and countries/regions in multiple instances. Surgical techniques (hemivertebra resection/posterior vertebral column resection/vertical expandable prosthetic titanium rib/double approach/grade 4 osteotomy) was one of the most common research focuses. In addition, research on genetics and molecular biology related to CS has become an emerging trend as a result of advances in basic science.

Over time, research on CS and in related fields has gained greater attention and has been expanding continuously, showing a trend toward globalization. We recommend that researchers focus on the progress of surgical techniques, advances in molecular biology and genetics, and characteristics of CS. The top clusters, most-cited articles, and references with the strongest burst citations should be studied further.
