Long term outcomes in periprosthetic femoral fractures: Experience from a UK district general hospital with a weekly dedicated periprosthetic theatre list and MDT approach

Arthroplasty of major joints ranks among the most common and successful orthopaedic procedures performed globally, as reflected in joint registry data. This trend, combined with longer life expectancy and a higher prevalence of comorbidities like osteoporosis, has contributed to a rising incidence of femoral periprosthetic fractures (PPFs) [1] Their incidence is projected to double in the next two decades as arthroplasty demand rises [[2], [3], [4]]. The presence of an arthroplasty component complicates or precludes standard fixation methods, a challenge further intensified by the frequent occurrence of these fractures in elderly patients with osteoporotic bone [5]. PPFs, which predominantly affect older patients with multiple comorbidities, are linked to serious medical complications, extended hospitalizations, and delayed recovery which contribute to high inpatient mortality [6]. One year mortality following PPF approaches that of native hip fracture, with large series reporting rates of 22–27 % [[7], [8], [9], [10]]. This has been related, in part, to a lack of geriatric co-management, an optimisation based approach with individualisation of surgical management has been suggested to enhance functional outcomes whilst reducing economic burdens [7].

Historically, optimal outcomes have been reported from tertiary, high-volume centres [11,12]. Yet most PFFs present to district general hospitals, where limited resources create the risk of delayed surgery, suboptimal decision-making, and institutionalization [13,14].

The fixation versus revision debate continues. Meta-analyses and multicentre studies confirm higher reoperation rates with fixation in unstable patterns, while revision arthroplasty provides more durable outcomes [[13], [14], [15], [16], [17]].

Globally, there is increasing recognition that system-level strategies such as multidisciplinary team (MDT) pathways, orthogeriatric optimisation, and enhanced recovery protocols — are critical determinants of outcomes [7,18]. Yet, evidence from district hospitals is sparse. Our study evaluates whether a dedicated weekly periprosthetic list with MDT involvement can deliver results comparable to those of large-volume centres.
