Hemarthrosis hip means bleeding into the hip joint space. It is a type of joint effusion, which is extra fluid inside a joint. Clinicians use this term when hip pain and swelling are linked to blood in the joint. It most often comes up in trauma care, postoperative care, and bleeding disorders.
Hemiarthroplasty is a joint replacement surgery where only one side of a joint is replaced. In the hip, it typically replaces the femoral head (the “ball”) while leaving the natural socket in place. It is commonly used after certain hip fractures, especially in older adults. It can also be performed in other joints, but the hip is the most well-known example.
Head-neck offset measurement describes how much the femoral head “steps out” from the femoral neck. It is a way to quantify hip shape that can influence how smoothly the ball-and-socket joint moves. Clinicians most often use it when evaluating femoroacetabular impingement (FAI) and related hip pain. It is commonly performed on hip X-rays and may also be assessed on MRI or CT images.
Head size is the diameter of the “ball” portion of the hip joint, called the femoral head. It can describe a person’s natural anatomy or the size of a prosthetic femoral head used in hip replacement. In orthopedics, Head size is most commonly discussed during total hip arthroplasty (THA) planning and implant selection. It is measured as a simple dimension (usually in millimeters) and used to help match anatomy and joint mechanics.
Hardinge approach is a surgical pathway to reach the hip joint through the side of the hip. It is also called a direct lateral approach or transgluteal approach in many clinical settings. Surgeons use it to perform hip operations such as hip replacement and fracture-related procedures. The approach is defined by how the tissues over the hip are opened and protected to access the joint.
Hamstring stretching refers to techniques used to lengthen the hamstring muscle–tendon unit at the back of the thigh. It is commonly used in sports medicine, physical therapy, and orthopedic rehabilitation. People often associate it with flexibility, comfort during activity, and movement quality. Clinicians may also use it as part of an exam to understand pain patterns and motion limits.
Hamstrings are a group of muscles and tendons along the back of the thigh. They help bend the knee and extend the hip, which is essential for walking, running, and climbing. Clinicians discuss Hamstrings in sports injuries, hip and pelvis pain, and gait (walking) problems. They are also relevant in certain surgeries where tendons may be used as a graft.
Hamstring origin refers to where the hamstring muscles begin (attach) on the pelvis. It is most commonly at the ischial tuberosity, the “sit bone” you feel when sitting. Clinicians use the term when describing buttock pain, tendon injuries, and sports-related strains. It is also used in imaging reports and surgical discussions about proximal hamstring problems.
GTPS stands for **greater trochanteric pain syndrome**. It is an umbrella term for **pain on the outside (lateral side) of the hip** near the bony prominence called the greater trochanter. GTPS is commonly used in **orthopedics, sports medicine, and physical therapy** to describe a typical pattern of lateral hip pain. It often relates to **gluteal tendon problems and nearby irritated soft tissues**, rather than an issue inside the hip joint itself.
Greater trochanteric pain syndrome is a clinical term for pain felt on the outside (lateral side) of the hip. It usually relates to irritation or injury of the tendons and soft tissues around the greater trochanter, a bony landmark on the upper femur. It is commonly used in orthopedics, sports medicine, and physical therapy to describe a recognizable pattern of lateral hip pain. It helps clinicians discuss diagnosis and management without assuming a single cause.
