The surgeon who treats your ankle fracture is more important than previously recognized

Short-term complications after ankle fracture surgeries could lead to poor, long-term patient outcomes

ROSEMONT, Ill. (August 15, 2019)—A wrong twist, rotation or roll could cause a broken ankle, also known as an ankle fracture, among people of all ages. One or more broken bones in an ankle joint can lead to instability and an active, older population of “baby boomers” have been seeing an increase in the number and severity of broken ankles. Among Medicare patients, ankle fractures are the third most common extremity fracture, costing more than half a billion dollars per year. Yet, according to new research published in the August 15 issue of the Journal of the American Academy of Orthopaedic Surgeons, the surgeon who treats your fracture may be more important to the healing process than previously recognized. The study authors at Stanford Health Care’s Department of Orthopaedic Surgery reviewed 11,745 records from an insurance claims database of patients between the ages of 20-80 treated for ankle fractures by orthopaedic surgeons[i],[ii] and podiatrists[iii] between 2007 and 2015.
 
The study specifically looked at several short-term complications after ankle fracture surgery:
  • the rate of fractures healing in a poor or incorrect position (malunion) within a year;
  • the rate of fractures that did not heal (nonunion) within a year; and,
  • the rate of infection, blood clots or repeat surgery for removal of unhealthy wound tissue within 90 days.
The study authors found a large difference in the rates of malunion and nonunion after comparing ankle fracture surgery outcomes by different surgeon types. Review of the insurance claims database revealed that “patients who had ankle fracture surgeries performed by podiatrists had a 50 percent increase in the rate of malunion or nonunion compared to surgery done by orthopaedic surgeons,” says lead researcher and orthopaedic surgeon Jeremy Chan, MD. “These differences were even higher in more complex ankle fracture patterns.”
 
Even though this study analyzed all types of orthopaedic surgeons, including those with subspecialized training in the foot and ankle trauma care as well as general orthopaedic surgeons, it was not designed to look at the causes for the differences, or long-term complications. Dr. Chan indicated that a range of factors could potentially influence the rates of fracture healing, which may include some surgeon-related factors (e.g., differences in surgical training between orthopaedic surgeons and podiatrists; volume of ankle fracture surgeries performed by individual surgeons). “This is important because ankle fractures that heal in a poor position or do not heal lead to future problems for patients such as continued pain, as well as the development of ankle arthritis long-term.”
 
Study highlights
  • There were no statistical differences in complications observed in patients with unimalleolar fractures—a fracture in one of the three components (i.e., medial, lateral, and posterior malleolus -- the bony components on each side of the ankle) that make up an ankle joint.
  • In patients with fractures in bimalleolar or trimalleolar fractures—two or three ankle joint components, respectively—treatment by a podiatrist was associated with higher malunion/nonunion rates.
  • Patients treated by orthopaedic surgeons versus podiatrists had similar comorbidity profiles (long-term or chronic conditions).
  • Despite higher malunion/nonunion rates, there is an increasing number of ankle fracture surgeries being performed by podiatrists over the past decade, whereas the number of ankle fracture surgeries being performed by orthopaedic surgeons is decreasing. However, over 90 percent of ankle fractures in this study sample were still treated by orthopaedic surgeons.
Given the potential risks associated with a poorly treated ankle fracture, “patients with ankle fractures undergoing surgery should consider choosing a physician with lower complication rates, and someone who routinely treats ankle fractures for the best outcome,” says Dr. Chan.
