Current Incidence and Future Projection of Periprosthetic Fractures in South Korea: A Study Based on National Claim Database

Abstract

To evaluate the current incidence and economic cost and to estimate the future burden of periprosthetic fracture (PF) after joint arthroplasties in South Korea. Methods:This study was a retrospective registry-based study of patients who were diagnosed as periprosthetic fractures (PFs) in South Korea. Cases of PF from 2010 to 2017 in South Korea using Health Insurance and Review and Assessment (HIRA) database, which contains all medical claims for all South Korean patients, were identified. The operational definitions of PFs were identified from the Electronic Data Interchange (EDI) code of the Korean National Health Insurance Program (KHNIP). The annual incidence and medical costs during the period were calculated and the future increase of PF and its cost were projected through 2030 using generalized linear model with quasi-poisson link.Results: During the 8-year period, 14,456 patients were treated due to PFs. The annual number of patients with PF remarkably increased from 1,322 in 2010 to 2,636 in 2017. The increment was prominent in age groups of 70-79 and ≧80. Total number of patients with PF were 9752 in women and 4704 in men during the study period.

Traumatic Floating Total Hip Arthroplasty

“…T his is a case of a 58-year-old woman with a medical history significant for a left THA 2 years prior, tobacco use, and L4-L5 posterior spinal fusion who presented with a left peri-prosthetic pelvic fracture and left periprosthetic femur fracture after a fall from a horse. This case emphasizes the increasing burden of periprosthetic fractures, which are known to be increasing in incidence as the population ages and the number of total joint arthroplasties performed increases [5][6][7] .…”

Fewer native and periprosthetic femoral fracture patients receive an orthogeriatric review and expedited surgery compared to hip fracture patients

“…The incidence of these injuries is projected to rise due to an ageing population and increased demand for arthroplasty procedures. 20 – 22 This issue is therefore important to consider for the future planning of the healthcare service and training more surgeons in revision arthroplasty techniques is warranted.…”
