We introduce an extension of the Lane and Sandhu Scoring system to serve as a more granular system for robust bone healing assessment in clinical research. We describe the application of this scoring system in the context of an autologous cell\u2010based osteogenic implant (NVD003) designed to improve the rate of bone union. Images from four participants with congenital pseudoarthrosis of the tibia (CPT) and 9 adults with recurrent osseous non\u2010union after conventional surgery were obtained. All participants underwent NVD003 implantation. An extended version of the Lane and Sandhu scoring system (eLSS; range from 0 to 12) was employed to assess bone formation, union, and remodeling by two independent readers longitudinally, with final adjudication in cases of &gt;\u20091 point disagreement. Interobserver agreement was assessed using quadratic weighted kappa. 206 exams (170 radiographs and 36 CT scans) were studied across the two pathologies (81 scans for participants with CPT and 125 scans for participants with recurrent osseous non\u2010union). Overall agreement between the expert readers was found to be 0.84 (95% CI: 0.79, 0.89), with comparable agreement found per modality (radiographs [0.85] and CT images [0.76]) and per pathology (CPT [0.83] and recurrent osseous non\u2010union [0.84]). These results support that the eLSS has sufficient reliability to warrant further consideration for clinical trial use. Additional studies with a greater number of subjects, raters, and variety of use cases are required to validate and optimize this method.<\/jats:p>\n                  <jats:p>\n                    <jats:bold>Level of Evidence:<\/jats:bold>\n                    III\n                  <\/jats:p>","DOI":"10.1002\/jor.70126","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T08:27:30Z","timestamp":1767169650000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Development of the Extended Lane and Sandu Score to Assess Osseous Repair"],"prefix":"10.1002","volume":"44","author":[{"given":"John A.","family":"Carrino","sequence":"first","affiliation":[{"name":"Department of Radiology and Imaging Hospital for Special Surgery New York USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1557-9484","authenticated-orcid":false,"given":"Hamza Ahmed","family":"Ibad","sequence":"additional","affiliation":[{"name":"Department of Radiology and Radiological Science Johns Hopkins University Baltimore Maryland USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikael","family":"Boesen","sequence":"additional","affiliation":[{"name":"Department of Radiology Copenhagen University Hospital Bispebjerg\u2010Frederiksberg Copenhagen Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Judy","family":"Ashworth","sequence":"additional","affiliation":[{"name":"Novadip Biosciences, Watson &amp; Crick Hill Mont\u2010Saint\u2010Guibert Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denis","family":"Dufrane","sequence":"additional","affiliation":[{"name":"Novadip Biosciences, Watson &amp; Crick Hill Mont\u2010Saint\u2010Guibert Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olga","family":"Kubassova","sequence":"additional","affiliation":[{"name":"Image Analysis Group London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,31]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-5898(20)30385-0"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0b013e3181a7c16d"},{"issue":"11","key":"e_1_2_10_4_1","first-page":"19982","article-title":"Gene Gun Transferring\u2010Bone Morphogenetic Protein 2 (BMP\u20102) Gene Enhanced Bone Fracture Healing in Rabbits","volume":"8","author":"Li W.","year":"2015","journal-title":"International Journal of Clinical and Experimental Medicine"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.2147\/IJN.S203859"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.21037\/atm-20-8198"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.engreg.2020.05.003"},{"key":"e_1_2_10_8_1","unstructured":"[Date unknown] \u201cStudy Details NVD\u2010003 in the Treatment of Congenital Pseudarthrosis of the Tibia \u201d ClinicalTrials.gov.https:\/\/clinicaltrials.gov\/study\/NCT05693558."},{"key":"e_1_2_10_9_1","unstructured":"[Date unknown] \u201cClinical Trials Register \u201dhttps:\/\/www.clinicaltrialsregister.eu\/ctr-search\/trial\/2018-000299-13\/BE."},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.2307\/2529310"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/rb\/rbaa031"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13018-014-0143-y"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.7150\/ijms.4242"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-015-0816-7"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.52312\/jdrs.2023.870"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.phymed.2022.153995"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-015-4331-9"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2025.112352"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/jor.22665"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.brs.0000186470.28070.7b"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1097\/BPB.0000000000000141"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00590-021-03134-6"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-015-4680-4"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.1097\/BOT.0000000000001811"},{"issue":"2","key":"e_1_2_10_25_1","doi-asserted-by":"crossref","first-page":"216","DOI":"10.1007\/s11420-019-09680-4","article-title":"Radiographic Humerus Union Measurement (RHUM) Demonstrates High Inter\u2010 and Intraobserver Reliability in Assessing Humeral Shaft Fracture Healing","volume":"16","author":"Christiano A.
