title: Intra-articular hip arthrodesis without subtrochanteric osteotomy in adolescents: technique and short-term follow-up.
abstract: Twenty-five patients, 11 to 19 years in age, were treated with hip arthrodesis for an incapacitating painful and stiff hip. Clinical diagnoses included avascular necrosis (AVN) associated with slipped capital femoral epiphysis (SCFE) (7 patients), posttraumatic AVN (6), septic arthritis (4), complication of treatment of developmental dysplasia of the hip (DDH) (4), pathologic fracture of femoral neck through bone cyst with resulting AVN (2), Perthes disease (1), and idiopathic chondrolysis (1). Preoperative motion was minimal or absent in 13 patients, limited in 12, and very painful in 23 patients. A two-incision surgical approach was utilized, providing for an intra-articular fusion technique and internal fixation with precise positioning. The surgical technique described avoids any dissection of the hip abductor musculature or a deforming osteotomy of the proximal femur. Twelve complications occurred in 10 patients, 9 of which required additional operative treatment. At an average postoperative follow-up of 6 years, 10 months, the overall activity level was greatly increased over the preoperative activity level secondary to the relief of pain. Hip arthrodesis is the acceptable salvage procedure for the otherwise healthy, active adolescent or young adult with unilateral hip disease characterized by incapacitating pain and/or an unacceptable fixed position.
