Abstract
Periprosthetic hip fractures may have features of atypical femoral fractures.
Purpose: Atypical femoral fracture (AFF) is a rare complication of treatment with bisphosphonates (BPs) or denosumab. The American Society for Bone and Mineral Research (ASBMR) Task Force definition for AFFs excludes periprosthetic fractures. The purpose of this study was to determine prodromal symptoms, frequency, treatment, and outcomes of periprosthetic AFFs (PAFFs) in persons prescribed a BP or denosumab for osteoporosis and later diagnosed with a periprosthetic hip fracture.
Methods: Participants were all veterans (age ≥ 50) from the VA Corporate Data Warehouse with at least one filled prescription for an oral or intravenous BP or denosumab from October 1999 through December 2022, prior to an ICD code for a periprosthetic fracture around a hip joint. Radiographs were reviewed for features of AFF. In those with a PAFF, the presence of a contralateral AFF was sought. Medical records of those with a PAFF were reviewed to identify prodromal symptoms, treatments, and outcomes.
Results: Among approximately 400,000 veterans who received a BP or denosumab, there were 76 ICD-coded periprosthetic hip fractures, including one AFF. This fracture met all five ASMBR-defined AFF criteria. The PAFF, a Vancouver C cemented periprosthetic femur fracture, occurred in a man with > 7 years of BP therapy. There was no contralateral AFF. The BP was discontinued and the fracture was treated with an interlocking plate with cerclage wires. In the 12 months following PAFF, there were no infectious complications, but the fracture had a chronic nonunion.
Conclusion: Periprosthetic hip fractures may rarely have features of AFFs. Fracture nonunion may complicate PAFFs.
期刊介绍：
An international multi-disciplinary journal which is a joint initiative between the International Osteoporosis Foundation and the National Osteoporosis Foundation of the USA, Osteoporosis International provides a forum for the communication and exchange of current ideas concerning the diagnosis, prevention, treatment and management of osteoporosis and other metabolic bone diseases.
It publishes: original papers - reporting progress and results in all areas of osteoporosis and its related fields; review articles - reflecting the present state of knowledge in special areas of summarizing limited themes in which discussion has led to clearly defined conclusions; educational articles - giving information on the progress of a topic of particular interest; case reports - of uncommon or interesting presentations of the condition.
While focusing on clinical research, the Journal will also accept submissions on more basic aspects of research, where they are considered by the editors to be relevant to the human disease spectrum.
