The cases were divided into an FNS group (21 cases) and a THA group (16 cases) based on the surgical method used. A comparative analysis was performed between the cohorts regarding demographic characteristics (sex and age), perioperative parameters (length of hospital stay, surgical duration, and intraoperative blood loss), and postoperative functional outcomes [Visual Analog Pain Score (VAS) and Harris Hip Score (HHS) assessments].<\/jats:p><\/jats:sec><jats:sec><jats:title>Result<\/jats:title><jats:p>The operative time, length of hospital stay, and intraoperative blood loss in the FNS group were significantly lower than those in the THA group, and the time of weight bearing on the ground in the FNS group was significantly longer than that in the THA group (<jats:italic>P<\/jats:italic>\u2009&amp;lt;\u20090.01). The comparative analysis revealed comparable outcomes in postoperative pain intensity (VAS) and functional recovery (HHS) between the cohorts, with both parameters demonstrating statistically equivalent values (<jats:italic>P<\/jats:italic>\u2009&amp;gt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>For unstable femoral neck fractures, FNS and THA were equally effective. Although shortening and necrosis were observed in the FNS group, no statistically significant difference in postoperative complications was found between the two groups. The operative time of FNS was shorter, with less intraoperative bleeding. However, the earlier weight-bearing time of THA was more conducive to the recovery of limb function.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fsurg.2025.1537335","type":"journal-article","created":{"date-parts":[[2025,6,6]],"date-time":"2025-06-06T05:22:29Z","timestamp":1749187349000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["A short-term efficacy comparison between the FNS and THA as interventions for unstable femoral neck fracture"],"prefix":"10.3389","volume":"12","author":[{"given":"Kunpeng","family":"Si","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuelei","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,6,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1563","DOI":"10.1148\/rg.2015140301","article-title":"Proximal femoral fractures: what the orthopedic surgeon wants to know-erratum","volume":"35","author":"Sheehan","year":"2015","journal-title":"Radiographics"},{"key":"B2","doi-asserted-by":"publisher","first-page":"341","DOI":"10.1186\/s13018-023-03827-0","article-title":"Total hip arthroplasty for failed internal fixation of femoral neck fracture: a retrospective study with 2\u201314 years\u2019 follow-up of 345 patients","volume":"18","author":"Lu","year":"2023","journal-title":"J Orthop Surg Res"},{"key":"B3","doi-asserted-by":"publisher","first-page":"l2178","DOI":"10.1136\/bmj.l2178","article-title":"Avascular necrosis of the hip","volume":"365","author":"Lamb","year":"2019","journal-title":"Br Med J"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1341","DOI":"10.2106\/JBJS.21.01411","article-title":"Total hip arthroplasty leads to better results after low-energy displaced femoral neck fracture in patients aged 55 to 70 years: a randomized controlled multicenter trial comparing internal fixation and total hip arthroplasty","volume":"104","author":"Bartels","year":"2022","journal-title":"J Bone Joint Surg Am"},{"key":"B5","doi-asserted-by":"publisher","first-page":"131","DOI":"10.1097\/BOT.0000000000000739","article-title":"Biomechanical evaluation of the femoral neck system in unstable Pauwels \u2162 femoral neck fractures: a comparison with the dyna-mic hip screw and cannulated screws","volume":"31","author":"Stoffel","year":"2017","journal-title":"J Orthop Trauma"},{"key":"B6","doi-asserted-by":"publisher","first-page":"2053","DOI":"10.1056\/NEJMcp1611090","article-title":"Management of acute hip fracture","volume":"377","author":"Bhandari","year":"2017","journal-title":"N Engl J Med"},{"key":"B7","doi-asserted-by":"publisher","first-page":"34","DOI":"10.1186\/s12938-022-01006-6","article-title":"Biomechanical comparison of the femoral neck system versus InterTan nail and three cannulated screws for unstable Pauwels type III femoral neck fracture","volume":"21","author":"Wang","year":"2022","journal-title":"Biomed Eng Online"},{"key":"B8","doi-asserted-by":"publisher","first-page":"1573","DOI":"10.3390\/medicina58111573","article-title":"Internal fixation of garden type III femoral neck fractures with sliding hip screw and anti-rotation screw: does increased Valgus improve healing?","volume":"58","author":"Hgel","year":"2022","journal-title":"Medicina (Kaunas)"},{"key":"B9","doi-asserted-by":"publisher","first-page":"400","DOI":"10.13362\/j.jpmed.202405006","article-title":"Efficacy of femoral neck internal fixation system versus arthroplasty in treatment of Pauwels type \u2162 femoral neck fracture","volume":"39","author":"Qu","year":"2024","journal-title":"J Precis Med"},{"key":"B10","doi-asserted-by":"publisher","first-page":"1143","DOI":"10.11817\/j.issn.1672-7347.2022.220022","article-title":"Biomechanical study on parallel cannulated compression screw combined with medial buttress plate fixation and F-type cannulated compression screw fixation in Pauwels III femoral neck fracture: a finite element analysis","volume":"47","author":"Wang","year":"2022","journal-title":"J Cent South Univ (Med Sci)"},{"key":"B11","doi-asserted-by":"publisher","first-page":"2672","DOI":"10.1007\/s11999-015-4345-3","article-title":"Does arthroplasty provide better outcomes than internal fixation at mid-and long-term followup?
