Borderline hip dysplasia is a term used when the hip socket provides slightly reduced coverage of the femoral head. It sits between a clearly normal hip and more definite (frank) acetabular dysplasia. Clinicians commonly use it when evaluating hip pain, clicking, instability sensations, or labral problems. It is most often discussed in orthopedics, sports medicine, hip preservation clinics, and physical therapy.
Bone scan is a nuclear medicine imaging test that shows how active different areas of bone are. It uses a small amount of radioactive tracer and a special camera to detect tracer uptake in the skeleton. Bone scan is commonly used when pain or symptoms are present but standard X-rays do not fully explain why. It is used in orthopedics, sports medicine, oncology, and emergency care to evaluate many bone-related conditions.
Bone marrow edema syndrome is a clinical diagnosis used when a person has significant joint pain and an MRI shows bone marrow edema without a clear destructive cause. “Bone marrow edema” means extra fluid-like signal within the spongy bone on MRI. It is most commonly discussed around the hip, but it can also involve the knee, ankle, or foot. The term is used in orthopedics and sports medicine to describe a pattern of pain plus imaging findings that may be temporary.
Bone marrow edema MRI is an MRI finding that shows increased fluid-like signal within bone marrow. It is most commonly discussed in hips, knees, ankles, and the spine. Clinicians use it to evaluate pain when X-rays are normal or do not explain symptoms. It helps describe bone stress, inflammation, or injury patterns inside the bone.
Bone marrow edema is a descriptive term for extra fluid within the bone marrow. It is most commonly seen as a finding on MRI (magnetic resonance imaging). Clinicians use it to help explain pain and to narrow down likely causes of joint symptoms. It is not a single disease by itself, but a pattern that can appear in many conditions.
BMAC injection hip refers to injecting bone marrow aspirate concentrate (BMAC) into or around hip structures. BMAC is made by collecting bone marrow and concentrating selected components, then using it the same day. It is commonly discussed in orthopedics and sports medicine for certain hip joint or soft-tissue problems. It is considered a biologic or “orthobiologic” treatment rather than a traditional drug or implant.
BMI stands for “body mass index.” It is a simple number calculated from height and weight. Clinicians use BMI as a screening tool to estimate whether body size may affect health risks. It is commonly recorded in primary care, orthopedics, sports medicine, and preoperative planning.
A Bilateral gluteus medius tear means the gluteus medius tendon is torn on both hips. The gluteus medius is a key “hip abductor” muscle that helps stabilize the pelvis during walking. This term is commonly used in orthopedics, sports medicine, and physical therapy to explain certain patterns of lateral hip pain and limping. It is often discussed alongside greater trochanteric pain syndrome and hip abductor weakness.
Bilateral trochanteric bursitis describes pain and tenderness on the outside of both hips. It involves irritation of tissues near the greater trochanter, a prominent part of the thigh bone (femur). The term is commonly used in orthopedic, sports medicine, and physical therapy settings when lateral hip pain affects both sides. In practice, it often overlaps with a broader diagnosis called greater trochanteric pain syndrome.
Bilateral total hip arthroplasty is a surgery that replaces both hip joints with artificial components. “Bilateral” means both sides, and “total hip arthroplasty” means replacing the ball-and-socket joint. It is commonly used for advanced arthritis or joint damage affecting both hips. It may be done in one operation or in two separate operations, depending on the case.
