This initial 3-month window is the most critical period for evaluating the structural stability of the fracture, as the majority of progressive height loss occurs before solid bone union is achieved, directly influencing the decision to continue conservative management or transition to surgical intervention. Materials and Methods: In this retrospective study, 123 patients were allocated to control (n = 26), denosumab (n = 35), teriparatide (n = 30), or romosozumab (n = 32) groups. Treatment choice was non-randomized, driven by clinical pragmatism and patient preference. Serial changes in vertebral compression rate (VCR) and pain (VAS) were analyzed over 3 months using linear mixed models (LMMs) specifically adjusted for baseline imbalances in initial VCR. Results: In the unadjusted analysis, DMAB appeared to show a slower progression of compression compared to the control group. However, after adjusting for the initial VCR, no significant structural benefit was observed in any medication group (p &gt; 0.05), with all groups showing small effect sizes (Cohen\u2019s d &lt; 0.4). In contrast, unstable fracture morphology was identified as the most potent driver of vertebral collapse (\u03b2 = 2.758, 95% CI: 1.51\u20134.01, p &lt; 0.001). Clinically, the RM group showed significantly lower overall pain levels throughout the follow-up period compared to the control group (p = 0.014). Conclusions: Short-term osteoporosis medication does not significantly mitigate vertebral collapse during the acute phase of OVCFs. Practically, these findings suggest that unstable fracture morphology and the baseline VCR\u2014reflecting a potential \u2018floor effect\u2019 where less initially collapsed vertebrae may undergo more significant progression\u2014are more informative predictors of acute collapse than medication choice. Consequently, early imaging-based risk stratification is crucial to identify patients at high risk for progressive deformity, regardless of their pharmacological regimen.<\/jats:p>","DOI":"10.3390\/medicina62020299","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T12:49:44Z","timestamp":1770036584000},"page":"299","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Limited Impact of Short-Term Osteoporosis Medication on Vertebral Height Loss in the Acute Phase of Osteoporotic Vertebral Compression Fractures: A 3-Month Longitudinal Analysis"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1565-9978","authenticated-orcid":false,"given":"Jaehoon","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Daejeon Sun Hospital, Daejeon 34811, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bong-Ju","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Daejeon Sun Hospital, Daejeon 34811, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9273-7628","authenticated-orcid":false,"given":"Jae-Beom","family":"Bae","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Daejeon Sun Hospital, Daejeon 34811, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7497-9077","authenticated-orcid":false,"given":"Sang-bum","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Chungnam National University Sejong Hospital, Sejong 30099, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9320-0153","authenticated-orcid":false,"given":"Dong-Hwan","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Chungnam National University Sejong Hospital, Sejong 30099, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2696-4302","authenticated-orcid":false,"given":"Ja-Yeong","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Chungnam National University Sejong Hospital, Sejong 30099, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"934","DOI":"10.31616\/asj.2022.0441","article-title":"Management of osteoporotic vertebral fracture: Review update 2022","volume":"16","author":"Jang","year":"2022","journal-title":"Asian Spine J."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"476","DOI":"10.31616\/asj.2024.0467","article-title":"Impact of sarcopenia on outcomes following vertebral augmentation for osteoporotic vertebral compression fracture: A systematic review and meta-analysis","volume":"19","author":"Nguyen","year":"2025","journal-title":"Asian Spine J."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"928","DOI":"10.31616\/asj.2025.0147","article-title":"Identifying early risk factors for chronic pain development following vertebral fractures: A single-center prospective cohort study","volume":"19","author":"Kondo","year":"2025","journal-title":"Asian Spine J."},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"23","DOI":"10.4184\/jkss.2024.31.1.23","article-title":"Understanding K\u00fcmmell\u2019s Disease: Definition, Diagnosis, Pathophysiology, and Treatment","volume":"31","author":"Ko","year":"2024","journal-title":"J.
