Hip Arthrodesis

  • Fusion (ANKYLOSIS) can occur spontaneously following childhood sepsis, following ORIF of acetabular fractures (secondary to heterotopic bone) and in ankylosing spondylitis

  • Unpopular as leads to increased stress on other hip and ipsilateral knee

  • Oxygen consumption 32% greater than normal

  • Average walking speed 84% of normal

 Indication

  • Young patient with unilateral hip disease (usually post-traumatic)

  • Contra-lateral hip, both knees and spine must all be normal

 Technique

  • Anterior or posterior approach inorder to dislocate the hip and to remove the joint surfaces

  • AO Cobra Plate: stable but disrupts abductors

  • Trans-articular sliding hip screw

  • lag screw is inserted across the joint and just superior to the dome of the acetabulum

  • disadvantage of this technique includes poor fixation (due to large lever arm and the resulting torque on the lever arm) and need for postoperative hip spica casting

  • Some authors advocate supra-acetabular osteotomy or subtrochanteric osteotomy for improved positioning
