Age-related bone fragility

The integration of translational research and innovation into orthopedic clinical care, as seen in the Fragility Fracture Program, sets Baylor St. Luke’s Medical Center apart as a top-tier academic health care institution. Dr. Florent Elefteriou, associate director of the Center for Skeletal Medicine and Biology at Baylor, investigates the complex interactions between the brain and bone cells. His laboratory studies the contribution of autonomic nerves to the progressive bone loss experienced in everyone as a function of aging, beginning in the third decade of life. Through targeted studies, they have been able to demonstrate that drugs, safely used for the management of cardiovascular diseases, have a protective effect against the bone fragility associated with aging. These findings have direct implications in the care of elderly fracture patients.

Orthopedic surgeons offer recipe for successful same-day hip and knee replacements

Needing a surgical procedure in the midst of the COVID-19 pandemic may seem daunting for many, so options where patients do not require a hospital stay are optimal.

Dr. Mohamad Jamal Halawi, chief quality officer for musculoskeletal services at Baylor St. Luke’s Medical Center, explains how he is able to perform same-day hip and knee replacements.

“It is important to resist the tunnel vision where one looks only at the hip or the knee. Rather, I am interested in the whole patient. What is their social support system like? What medical problems do they have? We want the best possible outcomes for patients, and the optimization process starts from day one.”
It’s important to address any active medical issues so that once the patient has the surgery, their hip and knee have their undivided attention, Halawi said.

Because Halawi educates his patients about exercises and has them start on these exercises ahead of surgery, patients rarely need to seek physical therapy after their joint replacement. This means one less outing during the COVID-19 pandemic.

Halawi also involves a patient’s caregiver to ensure that the patient has the support and reassurance they will need for a successful recovery.
“While most patients are able to independently care for themselves, teaming up with caregivers can help further improve their recovery,” he said.
One of the biggest anxieties that patients tend to have is about pain. However, Halawi has found that the vast majority of his patients do not require opioids to manage their post-surgical pain. In general, Halawi said that most patients are able to manage pain using over-the-counter pain medications.
Halawi, who is an avid scientist and the director of the Department of Orthopedic Surgery Outcomes Center at Baylor, emphasizes that this is possible thanks to a number of perioperative advancements. These include minimally invasive surgery, better anesthesia techniques, and safer analgesia protocols that target the pain pathway at many levels and even preempt it before the surgery.

“It is a powerful experience when a patient wakes up after surgery not having any pain. We are now able to stand ahead of the pain and avoid having to catch up like we used to do in the past,” he said.

Last but not least, being easily available to address patient questions or concerns following procedures is another very important ingredient for successful same-day surgery.

What used to take us days to achieve, now we can achieve in literally an hour or two after patients wake up from anesthesia,” Halawi said. “When you talk about a situation like the COVID-19 pandemic, where patients may be anxious, and understandably so, providing the option to recover safely and effectively from the comfort of one’s home is important, as delaying surgery will only prolong pain and reduce function.”

Halawi emphasizes that there is no cookie-cutter approach for all patients. It’s important to take a personalized approach and understand where each patient is coming from, tackle their concerns, and offer a more tailored procedure that meets their individual needs. This leads to a smoother recovery following surgery.

Meet Dr. Cahill

Dr. Catherine Cahill is trained in non-operative and operative musculoskeletal care and specializes in hip and knee surgery. She is affiliated with Kelsey Seybold.
Dr. Catherine Cahill explains how she is able to perform same-day hip and knee replacements and why most of her patients do not require strong pain medications, such as opioids, during recovery.
“There is a recipe for success to go home on the same day of the surgery while still maintaining the same recovery criteria as those who require overnight hospitalization or longer. What I do is facilitate patients achieving those milestones a lot quicker,” said Cahill.

Why is diversity for women and minorities important in orthopedic surgery?

Orthopedic surgery is the least diverse medical specialty in terms of both gender and those under-represented in medicine (URM). A diverse orthopedic workforce is a key component in addressing health disparities and inequities.

In 2013, the percentage of women residents in orthopedic surgery was 14%. Despite current medical school classes being split evenly by sex, the percentage of women in orthopedic surgery residencies has remained fairly constant (between 13% and 15%) for the past decade. In 2016, 86.6% of orthopedic surgeons reported as Caucasian, 6.7% reported as Asian, 1.7% reported as Hispanic or Latino, 1.5% reported as African American, 1.2% reported as multiracial, 1.7% reported as other, and 0.4% reported as Native American. The U.S. Census Bureau predicts that Asians, African Americans, Hispanics, and Latinos will soon compose 30% of the population, and by 2042, will be greater than 50%. Minority physicians continue to provide the majority of care for underserved and non-English speaking populations.
While the U.S. population has become more diverse, the orthopedic surgery workforce has not kept pace. Efforts will need to be made at the departmental, institutional, and national organizational levels to improve these conditions.
