Evaluate outcomes of Vancouver B2-type and B3-type proximal femur periprosthetic fractures (PPFs) in elderly patients treated with a cementless tapered modular femoral stem. Methods. 37 patients with a proximal femur PPF (34 B2-type and 5 B3-type) on primary or revision implants, with a minimum of 2-year follow-up, treated with revision of the failed stem using uncemented MP® reconstruction system stem (Waldemar Link®), were included.Results. At last follow-up, the average Harris Hip Score was 91 ± 9.8, and average Numerical Rating Score was 0.7 ± 0.8, without a significant difference between B2-type and B3-type PPFs. X-rays at last follow-up revealed bone union in all patients. According to Beals and Tower’s criteria, we found excellent radiological findings in 89.7% patients. Fourteen local surgery-related complications were reported (35.9%), and 4 patients required revision surgery (10.2%), without significant differences between B2-type and B3-type PPFs. We found involvement of both trochanters in fracture as a possible risk factor for dislocation.Conclusions. Vancouver B2-type and B3-type PPFs can be effectively treated using a cementless modular stem, even without cortical struts graft, although further studies are needed regarding B3-type PPFs.","journal":"LO SCALPELLO-OTODI Educational","year":2021,"id":226955,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8918,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":701776,"name":"Michele Fiore","orcid":"0000-0003-0546-670X","position":1,"is_corresponding":false},{"id":830340,"name":"Claudio Giannini","orcid":"0000-0002-5786-6767","position":2,"is_corresponding":false},{"id":830341,"name":"Riccardo Zucchini","orcid":"0000-0002-3485-101X","position":3,"is_corresponding":false},{"id":830342,"name":"Andrea Sambri","orcid":"0000-0002-2099-8547","position":4,"is_corresponding":false},{"id":830343,"name":"Massimiliano De Paolis","orcid":"0000-0002-6182-9870","position":5,"is_corresponding":false},{"id":830781,"name":"Calogero Alfonso","orcid":null,"position":0,"is_corresponding":true}],"reference_count":33,"raw_metadata":null,"created_at":"2026-07-18T23:54:38.004707Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
