TOTAL HIP-ARTHROPLASTY IN AN ADULT WITH PROXIMAL FEMORAL FOCAL DEFICIENCY

A 40-year-old woman with isolated unilateral proximal femoral local de ficiency presented with 2 years of gradually increasing left hip pain that interfered with her activities of daily living. A total hip arthr oplasty was performed through a posterior approach. At 12 months, she had minimal discomfort about the hip, a markedly increased level of ac tivity, and improved gait, and she required no ambulatory aids. This p rocedure is cautiously recommended for use in selected patients with p roximal femoral focal deficiency.
