Hip arthrodesis: a procedure for the new millennium?

Advanced hip arthrosis in the young patient represents a difficult problem. Using currently available techniques, total hip arthroplasty (THA) in this patient population likely would result in multiple revision surgeries, usually at the expense of bone in the proximal femur and acetabulum. For noninflammatory, monoarticular hip arthritis, arthrodesis remains an excellent reconstruction option. Arthrodesis can provide pain relief and return to function in the majority of patients indicated for the procedure. Current techniques provide acceptable fusion rates. If possible, techniques that protect the abductor mechanism and limit deformity of the pelvis should be used. Patient education is an important part of the treatment process. The position of the limb is important to early satisfaction and durability of the fusion. Long-term difficulties after hip fusion are related to pain in contiguous joints. Conversion arthroplasty, if necessary, can result in favorable outcomes. Familiarity with the techniques and outcomes of hip arthrodesis are important for the hip surgeon to understand.
