Navicular bursa: injection

Contributor(s): Vetstream Ltd

Introduction

  • Intra-articular analgesia of the navicular bursa can help to differentiate navicular pain from that of other parts of the palmar foot.

The significance of a positive response to analgesia of the navicular bursa has not been established.

  • Corticosteroid injection into the bursa has been advocated as a treatment for navicular syndrome.
  • The 'navicular position', ie of the navicular bone, is predictable and a reliable landmark for accurate needle placement:
    • 1 cm distal to the coronary band and halfway between the most dorsal and most palmar aspect of the coronary band.

Uses

Advantages

  • Accurate deposition of analgesic/therapeutic agent.
  • Weightbearing or non-weightbearing techniques may be used.
  • The 'navicular position' (non-weightbearing) technique:
    • Is more likely to result in successful injection of the bursa than the other techniques by inexperienced technicians.
    • Relaxes the deep digital flexor tendon and opens the bursal space between the tendon and the navicular bone.

Disadvantages

  • Difficult.
  • Multiple techniques described.
  • Real-time radiographic guidance an advantage.
  • Some techniques require penetration of the deep digital flexor tendon.
  • Non-weightbearing technique may pose additional hazard to personnel.
