Body Mass Index and Joint Replacement Surgery

Calculate Your BMI

What Is Body Mass Index [BMI]

Your BMI is a measurement of your body weight based on your height and weight. Although your BMI does not actually “measure” your percentage of body fat, it is a useful tool to estimate a healthy body weight based on your height. Due to its ease of measurement and calculation, it is the most widely used diagnostic indicator to identify a person’s optimal weight depending on his height. Your BMI “number” will inform you if you are underweight, of normal weight, overweight, or obese. However, due to the wide variety of body types, the distribution of muscle and bone mass, etc., it is not appropriate to use this as the only or final indication for diagnosis.

The formulas to calculate BMI based on two of the most commonly used unit systems:

BMI = weight(kg) / height(m) (Metric Units)
BMI = 703·weight(lb) / height(in) (U.S. Units)

BMI Table for Adults

This is the World Health Organization’s (WHO) recommended body weight based on BMI values for adults. It is used for both men and women, age 18 or older. The Body mass chart for adults and the body mass chart for children is different. This is because body mass index is accounted differently based on age and growth spurts. Here is the Body Mass Index Chart for women and for men that are 18 and older:

Complete Guide to Clavicle Fracture Treatment

Clavicle fractures, commonly known as broken collarbones, are among the most frequent bone injuries I treat in my practice, affecting everyone from newborns to elderly adults. Most clavicle fractures heal well with proper treatment, which can range from simple sling immobilization for stable fractures to surgical repair for complex breaks. Understanding the different collarbone fracture types, treatment options, and recovery expectations can help you make informed decisions about your care and get back to your normal activities safely.

Understanding Acetabular Reaming in Hip Replacement Surgery

Acetabular reaming is the surgical process that prepares your hip socket during total hip replacement, and it's one of the most critical steps affecting your long-term outcomes. Using specialized hemispherical tools, surgeons carefully shape the bone to create the perfect fit for your new implant. Recent advances in robotic-assisted surgery have transformed this process, allowing for CT-based planning and real-time precision that was impossible just a few years ago. Research now shows that enhanced reaming depth techniques can actually improve implant stability while reducing bone strain and fracture risks. Whether you're considering hip replacement or simply want to understand what happens during surgery, this guide explains the reaming process, why precision matters, and how modern technology helps surgeons achieve better results. Learn what questions to ask your surgeon and what factors affect the approach used for your specific anatomy.

Outpatient Joint Replacement Surgery

Total joint replacements are more commonly being performed in outpatient facilities, rather than in a hospital. Depending on several factors, patients may be eligible to have total hip or knee replacement done as an outpatient and go home the same day. Bone and Joint Institute of Tennessee physicians perform outpatient total joint replacements at the ambulatory surgery center (ASC) on the campus of Williamson Medical Center in Franklin, Tennessee.
