A new position statement from the International Osteoporosis Foundation's (IOF) Committee of Scientific Advisors Fracture Working Group urges orthopaedic surgeons and bone health specialists to work together to assess and treat osteoporosis before and after joint replacement and spinal fusion surgery.
Bringing together expertise across multiple disciplines, the position paper presents a framework linking poor bone quality to complications across both types of procedures and provides evidence-informed recommendations to improve outcomes for the millions of patients undergoing these surgeries worldwide. It introduces the concept of implant fixation failure as a common endpoint, describing the progressive mechanical failure of bone–implant constructs resulting from compromised bone quality specifically that due to osteoporosis.
The problem: osteoporosis is undermining surgical success
Each year, millions of hip replacements and spinal fusions are performed globally, with numbers continuing to rise as populations age. While these procedures are highly effective, a growing proportion of complications, including periprosthetic fractures, implant loosening, cage subsidence, pseudoarthrosis (non-union), and junctional failure, arise from the interaction between osteoporotic bone and orthopaedic implants.
Lead author and co-chair of the IOF Fracture Working Group, Professor Manju Chandran, Singapore General Hospital, and Clinical Professor, DUKE NUS Medical School, Singapore stated: “We urge the orthopaedic and bone health communities to see implant failure and osteoporosis as two sides of the same coin. A hip replacement, or a spinal fusion, is only as durable as the bone that supports it. We need to think about bone quality as a determinant of surgical durability, not just fracture risk. Identifying and treating osteoporosis before and after these operations is a practical, low-cost way to protect patients from painful, dangerous, and expensive complications.”
Key findings
The position statement synthesizes evidence from randomized controlled trials, cohort studies, registry analyses, meta-analyses, and systematic reviews. Among the key findings:
Expert recommendations
Among the expert recommendations for peri-operative bone health optimization are the following:
A call for bone health optimization
The authors emphasize that bone health optimization should not be treated as an adjunct to surgical care, but as an integral component of peri-operative planning.
Professor Eugene McCloskey, Mellanby Centre for Musculoskeletal Research, University of Sheffield, UK and chair of the IOF Committee of Scientific Advisors, added: “This is a very important and timely position statement which calls for a fundamental shift in how orthopaedic and metabolic bone specialists collaborate. I highly commend the Fracture Working Group for highlighting this important clinical gap and providing a roadmap for more integrated care. Every patient undergoing arthroplasty or spinal fusion who has or is at risk of poor bone quality deserves a structured assessment and, where indicated, targeted therapy. This would help improve surgical outcomes and reduce complications for patients worldwide.”
