Damaged head of femur is replaced-Must have normal acetabulum-More conservative than THRRehab Similar to THR
A
Hemiarthroplasty
B
Proximal hip osteotomy
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -In a total hip replacement (also called total hip arthroplasty), the damaged bone and cartilage is removed and replaced with prosthetic components. The damaged femoral head is removed and replaced with a metal stem that is placed into the hollow center of the femur.

Detailed explanation-2: -Total hip replacement (the most common type): A total hip replacement switches both the femoral head and the acetabulum with a prosthesis. Partial hip replacement: A partial replacement substitutes the femoral head only. This is typically done for patients with certain types of hip fractures.

Detailed explanation-3: -Abstract. Background: Contemporary total hip arthroplasty (THA) employs larger femoral heads to optimize hip stability. However, the combination of large femoral heads and comparatively small acetabular components poses a potential risk for implant failure secondary to polyethylene (PE) liner fracture or dissociation.

Detailed explanation-4: -Total Hip Replacement It uses artificial components to replace the entire hip structure. During the procedure, surgeons insert a stem into the patient’s femur, or thighbone, for stability. They replace the head of the femur with a ball and replace the natural socket in the hip joint with an artificial cup.
