Transient osteoporosis of the hip is a temporary condition where the bone in and around the hip becomes less dense and inflamed. It most often affects the femoral head and neck (the “ball” and upper part of the thigh bone). It commonly shows up as sudden hip pain and difficulty walking, despite no major injury. In clinical practice, it is mainly used as a diagnosis to explain hip pain and characteristic MRI findings that typically resolve over time.

Trabecular metal is a porous metal material used in some orthopedic implants. It is designed to help bone attach and grow into the surface of an implant. It is commonly used in joint reconstruction, especially hip and knee surgery. It may be used in both first-time (primary) and repeat (revision) procedures.

Total hip replacement surgery is an operation that replaces a painful, damaged hip joint with artificial parts. It is most commonly used for advanced hip arthritis and other conditions that wear down the joint surfaces. The goal is to restore smoother movement and reduce pain when non-surgical care is no longer enough. It is performed by orthopedic surgeons in hospitals or surgical centers.

Total hip replacement is a surgical procedure that replaces a damaged hip joint with artificial components. It is commonly used to reduce pain and improve function when the hip joint has advanced wear or injury. Clinicians may also call it “total hip arthroplasty,” meaning reconstruction of the entire hip joint. It is most often performed for long-standing hip arthritis that limits daily activities.

Total hip arthroplasty uncemented is a type of total hip replacement that uses implants designed to attach to bone without bone cement. It replaces both the ball (femoral head) and socket (acetabulum) of the hip joint. It is commonly used for hip arthritis and other conditions that damage the joint surfaces. The goal is to restore smoother motion and reduce pain by replacing the worn joint with artificial components.

Total hip arthroplasty cemented is a type of hip replacement where bone cement helps fix the implant to bone. It replaces both the ball and socket of the hip joint with artificial parts. It is commonly used when immediate, reliable fixation is needed, often in older adults or people with weaker bone. It may also be chosen in certain fracture and revision (repeat surgery) situations.

Total hip arthroplasty is a surgery that replaces a damaged hip joint with artificial parts. It is commonly called a “total hip replacement.” It is most often used for hip arthritis and other conditions that severely damage the joint. The goal is to reduce pain and improve hip function for daily activities.

TTWB stands for “toe-touch weight bearing.” It means the foot may touch the ground for balance, but body weight is kept off the limb. TTWB is commonly used after hip, pelvis, femur, knee, or ankle injuries and surgeries. It is a mobility instruction used by orthopedic teams and physical therapists during recovery.

Toe-touch weight bearing is a walking restriction that allows your toes to lightly touch the floor while keeping most body weight off the injured or operated leg. It is commonly used after hip, pelvis, and lower-extremity surgery or fracture care to protect healing tissues. The toe contact is mainly for balance and positioning, not for supporting your weight. Clinicians may also call it “touch-down” weight bearing, depending on local terminology.

Tilt table (not applicable) is a clinical device that safely changes a person’s body position from lying flat to partially or fully upright. It is commonly used in hospitals, rehabilitation centers, and diagnostic labs. Clinicians use it to assess how the body responds to gravity and standing-like positions. It can also be used to help patients practice upright tolerance when regular standing is difficult.
