The study compares the results of PFNA and TFNA implants (DePuy Synthes) with or without cement augmentation of the blade. Methods: A retrospective study evaluated 219 trochanteric fractures. The study included 59 men (27%) and 160 women (73%), with a mean patient age of 82 years. The most common fractures were type 31A2 (56%), followed by type 31A1 (25%) and type 31A3 (19%). The monitored parameters were evaluated from anteroposterior and axial images of the proximal femur and pelvis. TAD, blade position, lateral blade prominence, fracture varus, and cut-out were evaluated. Results: Cement-augmented blade implants (CABs) in 68 patients (31%) and cement-free implants (NCABs) in 151 patients (69%) were used. The average age difference between the groups was 7 years (CAB 86.07 \u00b1 5.85 and NCAB 79.13 \u00b1 8.48). CABs were used more frequently in women (60 cases) than in men (8 cases). Blade position was optimal in 68% of cases and suboptimal in 32%. The risk of varus deformities was not statistically significantly affected by the blade position. The statistical significance of CABs for reducing the risk of varus deformities in stable fractures (p = 0.396) or unstable fractures (p = 0.101) was not confirmed. The average varus angulation during treatment was 2.57\u00b0 (CAB 2.53\u00b0 and NCAB 2.67\u00b0). A varus deformity greater than 10\u00b0 was confirmed in 8 eight patients (3.7%) and cut-out in three patients (1.4%). All patients with cut-out were in the NCAB group. Cement leakage occurred in two cases and was asymptomatic. One case of deep infection, lateral blade prominence, and avascular necrosis (AVN) were recorded. Conclusions: Cement augmentation of the blade did not significantly reduce varus deformity in this cohort, regardless of blade position of fracture stability. CABs may prevent cut-out in specific subgroups, but this requires further investigation.<\/jats:p>","DOI":"10.3390\/jcm14217469","type":"journal-article","created":{"date-parts":[[2025,10,23]],"date-time":"2025-10-23T05:20:44Z","timestamp":1761196844000},"page":"7469","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Cement Augmentation of the Blade in Proximal Femoral Nailing for Trochanteric Fractures in Elderly Patients: A Retrospective Comparison of Mechanical Stability and Complications"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5688-7961","authenticated-orcid":false,"given":"Zoltan","family":"Cibula","sequence":"first","affiliation":[{"name":"Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, 036 59 Martin, Slovakia"},{"name":"Department of Orthopaedic Surgery, University Hospital Martin, Kollarova 2, 036 59 Martin, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marian","family":"Grendar","sequence":"additional","affiliation":[{"name":"Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, 036 59 Martin, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diaa","family":"Sammoudi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University Hospital Martin, Kollarova 2, 036 59 Martin, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2892-0687","authenticated-orcid":false,"given":"Milan","family":"Cipkala","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University Hospital Martin, Kollarova 2, 036 59 Martin, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marian","family":"Melisik","sequence":"additional","affiliation":[{"name":"Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, 036 59 Martin, Slovakia"},{"name":"Department of Orthopaedic Surgery, University Hospital Martin, Kollarova 2, 036 59 Martin, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0755-5570","authenticated-orcid":false,"given":"Maros","family":"Hrubina","sequence":"additional","affiliation":[{"name":"Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, 036 59 Martin, Slovakia"},{"name":"Department of Orthopaedic Surgery, University Hospital Martin, Kollarova 2, 036 59 Martin, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1389","DOI":"10.1007\/s00198-023-06774-y","article-title":"Trends in incidence, health care consumption, and costs for proximal femoral fractures in the Netherlands between 2000 and 2019: A nationwide study","volume":"34","author":"Zeelenberg","year":"2023","journal-title":"Osteoporos.
