Traditional systems are reliable, but they present some complications regarding lack of modularity or possible growth plate damage. Methods: A novel locking rod\u2013screw system featuring a central rod and a grooved screw with a secondary interlocking mechanism was developed and tested. Mechanical testing followed ASTM F543 and ISO 6475 standards using a 3.0 mm steel alloy prototype. Results: The system withstood mechanical testing &gt;200,000 cycles at loads up to 200 N with no rates of failure or loosening, significantly outperforming other implants of the same size (3.0 mm TENS). Conclusions: The proposed implant demonstrates superior biomechanical performance in vitro, enabled by its unique hollow screw and secondary locking configuration. This modular and minimally invasive system shows promise for use in cases of smaller long bones, personalized paediatric fractures, and all types of diaphyseal fractures, but does warrant in vivo validation.<\/jats:p>","DOI":"10.3390\/jfb16090348","type":"journal-article","created":{"date-parts":[[2025,9,15]],"date-time":"2025-09-15T16:27:33Z","timestamp":1757953653000},"page":"348","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Original Locking Rod System Designed for Diaphyseal Fractures of Long Bones"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-6430-3833","authenticated-orcid":false,"given":"Liviu-Coriolan","family":"Misca","sequence":"first","affiliation":[{"name":"Department of Orthopedics and Traumatology, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Department Orthopaedics and Traumatology, Cork University Hospital, T12 DC4A Cork, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristian Constantin","family":"Croicu","sequence":"additional","affiliation":[{"name":"Veterinaria Timisoara, 300502 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrian Emil","family":"Lazarescu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Spitalul Clinic Judetean de Urgenta \u201cPius Brinzeu\u201d Timisoara, 300723 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihai-Alexandru","family":"Sandesc","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Spitalul Clinic Judetean de Urgenta \u201cPius Brinzeu\u201d Timisoara, 300723 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr.","given":"Jenel Marian","family":"Patrascu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Spitalul Clinic Judetean de Urgenta \u201cPius Brinzeu\u201d Timisoara, 300723 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sorin","family":"Florescu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Spitalul Clinic Judetean de Urgenta \u201cPius Brinzeu\u201d Timisoara, 300723 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Sr.","given":"Jenel Marian","family":"Patrascu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Victor Babes University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Spitalul Clinic Judetean de Urgenta \u201cPius Brinzeu\u201d Timisoara, 300723 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1385","DOI":"10.1007\/s00402-010-1082-7","article-title":"Early history of operative treatment of fractures","volume":"130","year":"2010","journal-title":"Arch.
