Surgical approaches: posterior, anterolateral, direct anterior, transtrochanteric. Posterior: excellent exposure, preserves abductors, higher dislocation risk. Anterolateral: stable, lower dislocation, abductor weakness risk. Direct anterior: internervous, muscle-sparing, early rehab, risk of LFCN injury, intra-op fracture. Transtrochanteric: trochanteric osteotomy, good exposure, risk of nonunion. Complications: dislocation, infection, aseptic loosening, periprosthetic fractures, nerve injury, heterotopic ossification.
