Synonym(s): Femoral head and neck amputation, Femoral head and neck ostectomy, Femoral head excision, Gridlestone procedure

Contributor(s): Melvyn Pond, Prof Mark Rochat

Introduction

  • Removal of femoral head and neck to create pseudoarthrosis of hip joint.
  • Better results in small dogs and cats.

Uses

Advantages

  • Requires relatively little instrumentation.
  • Requires less surgical assistance, especially if done with a powered sagittal saw.
  • Does not require expensive implants.
  • Does not require strict postoperative confinement.

Disadvantages

  • Effectively reduces length of the limb so femoral shaft lies dorsal to normal position.
  • Reduces range of hip motion.
  • Most dogs rarely return to full function or have as much stamina as that provided by total hip replacement Joint replacement: overview.
  • Some degree of muscle atrophy invariably occurs.

Prognosis

  • Depends on integrity of surrounding soft tissues - too much scar tissue causes lameness due to reduced range of movement of pseudoarthrosis; pressure on sciatic nerve can cause lameness.
  • Immature animals respond better than adults.
  • Can be carried out bilaterally and simultaneously if required in small dogs but requires extra nursing care.
