During early ambulation after hip arthroplasty, how should the hip be positioned to protect the joint?

• A. Abduction and external rotation; keep the leg straight
• B. Avoid adduction and internal rotation; keep the hip in neutral alignment and follow precautions
• C. Flexion beyond 90 degrees with adduction
• D. Adduction with flexion and internal rotation

Answer: (C)

Protecting the hip prosthesis means avoiding positions that place the joint at risk for dislocation or stress. The hip should be kept in neutral alignment with the leg in slight abduction and without internal rotation. Do not flex the hip beyond about 90 degrees, and avoid adduction (bringing the leg toward the midline) or any internal rotation. This position reduces strain on the joint and surrounding tissues during early ambulation, helping prevent dislocation as the new joint heals. Use assistive devices and follow precautions during transfers and standing to maintain this safe alignment.
