Dunn view is a specialized hip X-ray view that shows the front part of the femoral head and neck more clearly than a standard pelvis X-ray. It is commonly used in orthopedics and sports medicine to evaluate hip shape and sources of hip pain. Clinicians often request it when femoroacetabular impingement (FAI) is suspected. It is a diagnostic imaging view, not a treatment.

Dunn 90 view is a specialized hip X-ray view taken with the hip flexed to about 90 degrees. It is designed to better show the shape of the femoral head and neck (the “ball” and the nearby bone). Clinicians commonly use it when evaluating hip pain, reduced motion, or suspected femoroacetabular impingement (FAI). It is one of several “lateral” hip projections that complement a standard front-view pelvis X-ray.

Dunn 45 view is a specialized X-ray view of the hip. It uses a specific leg and hip position to better show the femoral head–neck junction. It is commonly used in orthopedics and sports medicine when evaluating hip pain. It is often discussed in the context of femoroacetabular impingement (FAI) and related hip conditions.

Dynamic hip screw fixation is a surgical method used to stabilize certain hip and upper femur (thigh bone) fractures. It uses a large screw placed into the femoral head connected to a side plate on the femur. It is commonly used for many intertrochanteric hip fractures (breaks just below the femoral neck).

Dynamic hip screw is a metal implant used to stabilize certain hip fractures. It is most commonly used for fractures near the top of the thigh bone (proximal femur). It combines a large “sliding” screw with a side plate that attaches to the femur. Its design allows controlled compression at the fracture while maintaining alignment.

DHS most commonly refers to a **Dynamic Hip Screw**. It is an orthopedic implant used to stabilize certain **proximal femur (upper thigh bone)** fractures. It combines a large screw in the femoral head with a side plate along the femur. It is commonly used in hip fracture surgery, especially around the trochanteric region.

Dislocation risk means the chance that a joint will partially or fully slip out of place. It is commonly discussed for the hip because the hip is a weight-bearing ball-and-socket joint. Clinicians also use the term after hip replacement to describe the likelihood of prosthetic hip instability. It is used in orthopedic exams, surgical planning, rehabilitation, and patient education.

Dislocation precautions are movement and positioning limits used to reduce the chance that a hip joint “pops out of place.” They are most commonly discussed after hip replacement surgery and after certain hip injuries. They focus on avoiding positions that can lever the femoral head out of the socket. The exact precautions depend on the surgery type, surgical approach, and clinician preference.

Direct lateral approach THA is a surgical approach used to perform total hip arthroplasty (hip replacement). It reaches the hip joint from the outer (lateral) side of the hip. It is commonly used in primary hip replacement and in some revision settings. It is designed to provide reliable access to the hip while managing soft tissues around the joint.

Direct anterior approach is a surgical pathway to reach the hip joint from the front (anterior) of the body. It is most commonly discussed in the context of hip replacement surgery. The approach follows natural planes between muscles rather than routinely detaching major hip abductors. It is one of several established ways surgeons can access the hip.
