The aim of this study was to determine whether the age of menarche differs in scoliotic and non-scoliotic Balkan girls and the relationship between menarche and the laterality of scoliotic curves. Participants and Methods: This is a retrospective study with three groups: scoliotic, non-scoliotic, and control. Patient data collection and analysis were approved by the Ethical Committee of the Institute. Statistical Analysis: The SPSS 24 program was used, and we employed One-way ANOVA, Fisher\u2019s, and Chi-squared tests to compare different groups. Statistical significance was defined as p &lt; 0.05. Results: No statistically significant difference was found in the age of menarche between the three groups (p = 0.168). In the scoliotic postmenarchal group, the primary right curve was dominant in 54.80%, while in the scoliotic premenarchal group, the primary left curve was dominant in 60.09% (p &lt; 0.01). Conclusion: In Balkan girls from Bosnia and Herzegovina and Serbia, there was no significant difference in the age of menarche between scoliotic and non-scoliotic girls. A significant difference was found in the laterality of the primary curve in premenarchal and postmenarchal scoliotic girls.<\/jats:p>","DOI":"10.3390\/jcm13010132","type":"journal-article","created":{"date-parts":[[2023,12,26]],"date-time":"2023-12-26T04:40:44Z","timestamp":1703565644000},"page":"132","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Menarche in Scoliotic and Non-Scoliotic Balkan Girls and the Relationship between Menarche and the Laterality of Scoliotic Curves"],"prefix":"10.3390","volume":"13","author":[{"given":"Samra","family":"Pjanic","sequence":"first","affiliation":[{"name":"Department of Pediatric Rehabilitation, Institute for Physical, Rehabilitation Medicine and Orthopedic Surgery \u201cDr Miroslav Zotovic\u201d, 78000 Banja Luka, Bosnia and Herzegovina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7065-8401","authenticated-orcid":false,"given":"Nikola","family":"Jevtic","sequence":"additional","affiliation":[{"name":"Scolio Centar, 403916 Novi Sad, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3018-5168","authenticated-orcid":false,"given":"Theodoros B.","family":"Grivas","sequence":"additional","affiliation":[{"name":"Former Head of Department of Traumatology and Orthopaedics, \u201cTzaneio\u201d General Hospital of Piraeus, 18536 Piraeus, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,26]]},"reference":[{"key":"ref_1","first-page":"183","article-title":"Italian guidelines on rehabilitation treatment of adolescents with scoliosis or other spinal deformities","volume":"41","author":"Negrini","year":"2005","journal-title":"Eur.
