The sequelae of septic arthritis of the hip involve a spectrum of pathology. Clinical problems include pain, instability (Pistoning) from subluxation or dislocation, abductor insufficiency, and leg length discrepancy. The treatment must be individualized, and many options are available. Residual sepsis should be treated by debridement and antibiotics, and reconstruction should be delayed until sepsis has been controlled. Once the infection is eradicated, patients desiring stability at the expense of motion may consider an arthrodesis of the hip. For those desiring motion, options include resection arthroplasty, pelvic support osteotomy, and total joint arthroplasty. Limb length discrepancy is universal, and varies in magnitude.
