Background: Proximal femoral periprosthetic fractures are an increasingly common complication following hip arthroplasty and are associated with high surgical complexity, morbidity, and mortality, particularly in elderly and frail patients. Study Objective The primary aim of this study is to characterize the epidemiological, clinical, and surgical features, as well as the clinical–radiographic outcomes at follow-up—including survival, functional outcomes, and available clinical scores—of patients with periprosthetic proximal femoral fractures treated at the Orthopaedic Clinic of the University of Padua between 2009 and 2025. Methods: A retrospective observational single-center study was conducted on patients surgically treated for proximal femoral periprosthetic fractures. Fractures were classified according to the Vancouver classification. Demographic data, comorbidities, ASA score, fracture type, surgical strategy, complications, clinical and radiographic outcomes, one-year mortality, and overall survival were analyzed. Statistical significance was set at p < 0.05. This retrospective observational study was designed, conducted, and reported in accordance with the STROBE guidelines. Results: One-year mortality was 16.2%, reflecting the frailty of the study population. Advanced age and higher ASA classification were significantly associated with increased one-year mortality (p < 0.05). A higher number of comorbidities was significantly correlated with poorer functional outcomes and postoperative bedridden status (p < 0.05). No statistically significant association was found between Vancouver fracture type and survival (p > 0.05). Radiographic evaluation demonstrated satisfactory fracture union and implant stability in the majority of cases. Major and minor complications were mainly related to preoperative patient-related factors rather than fracture type or surgical technique. Conclusions: Proximal femoral periprosthetic fractures represent a sentinel event in a fragile population. Clinical and radiographic outcomes are primarily influenced by patient-related factors rather than fracture classification. A tailored surgical and perioperative approach is essential to optimize outcomes.
Introduzione: Le fratture periprotesiche del femore prossimale rappresentano una complicanza in costante aumento dopo artroplastica d’anca e sono associate a elevata complessità chirurgica, morbilità e mortalità, in particolare nei pazienti anziani e fragili. Obiettivo dello studio: L’obiettivo primario dello studio è descrivere le caratteristiche epidemiologiche, cliniche e chirurgiche, gli outcome clinico-radiografici al follow-up, inclusi outcome di sopravvivenza, funzionali e score clinici disponibili, dei pazienti affetti da frattura periprotesica di femore prossimale e trattati presso la Clinica Ortopedica dell’Università di Padova nel periodo 2009–2025. Materiali e metodi: È stato condotto uno studio osservazionale retrospettivo monocentrico su pazienti sottoposti a trattamento chirurgico per frattura periprotesica del femore prossimale. Le fratture sono state classificate secondo la classificazione di Vancouver. Sono stati analizzati dati demografici, comorbidità, classificazione ASA, tipo di frattura, strategia chirurgica, complicanze, outcome clinici e radiografici, mortalità a 1 anno e sopravvivenza globale. Le associazioni tra variabili cliniche e outcome sono state valutate mediante analisi statistica inferenziale, considerando significativo un valore di p < 0,05. Il presente studio osservazionale retrospettivo è stato progettato, condotto e riportato in conformità alle linee guida STROBE. Risultati: La mortalità a 1 anno è risultata pari al 16,2%, confermando l’elevata fragilità della popolazione studiata. L’età avanzata e la classificazione ASA elevata sono risultate significativamente associate a un aumento della mortalità a 1 anno (p < 0,05). Il numero di comorbidità ha mostrato una correlazione significativa con il peggioramento degli outcome funzionali e con l’allettamento postoperatorio (p < 0,05). Non è emersa un’associazione statisticamente significativa tra il tipo di frattura secondo Vancouver e la sopravvivenza (p> 0,05). Dal punto di vista radiografico, la maggior parte dei pazienti ha ottenuto una stabilità dell’impianto e una consolidazione di frattura soddisfacenti. Le complicanze maggiori e minori sono risultate prevalentemente correlate alle condizioni cliniche preoperatorie piuttosto che alla tipologia di frattura o alla tecnica chirurgica. Conclusioni: Le fratture periprotesiche del femore prossimale si configurano come un evento sentinella in una popolazione fragile. Gli outcome clinico-radiografici dipendono principalmente da fattori paziente-correlati piuttosto che dalla classificazione della frattura. Un approccio chirurgico individualizzato, integrato da un’accurata gestione perioperatoria, è fondamentale per ottimizzare i risultati clinici.
