Ex vivo study of minimally invasive procedures for cartilage removal from the metacarpophalangeal or metatarsophalangeal joint and for fetlock tension band application.

Abstract: To describe reliable minimally invasive procedures for (1) removing cartilage by joint distraction and articular drilling for equine metacarpophalangeal (MCP)/metatarsophalangeal (MTP) arthrodesis; (2) applying a palmar/plantar tension band without MCP/MTP joint luxation. Methods: Experimental study. Methods: Cadaveric equine limbs (n = 12). Methods: All limbs were used to evaluate the drilling technique. First the MCP/MTP joint was distracted with a 5.5-mm cortical screw. Then, through four stab incisions, articular cartilage was removed with a 4.5-mm drill. Six randomly chosen limbs were then tested for minimally invasive tension band application with a specially designed cannula. Accurate positioning of the tension band was assessed radiographically. All MCP/MTP joints were disarticulated, and the areas of removed cartilage were visually assessed and measured by using planimetry. Results: The mean percentage of removed cartilage was 66.8% ± 7.6% for the metacarpus/metatarsus surface, 67.9% ± 8.6% for the proximal phalanx surface, and 59.5% ± 1% for the two sesamoid bones. The tension band could be accurately placed through four stab incisions with the cannula. Conclusions: This minimally invasive technique for cartilage removal was efficient and should be favorable for joint fusion in some clinical situations. The minimally invasive tension band application through stab incisions was feasible and repeatable. Conclusions: These procedures should allow total minimally invasive MCP/MTP arthrodesis and be used in selected clinical cases.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The study demonstrates a minimally invasive procedure for the removal of cartilage from horse joints and the application of a supportive band, discovered during an examination of horse cadaver limbs. The techniques presented may enhance the efficacy of joint fusion and can be repeatable for various situations.

Research Methodology

  • The research was conducted using 12 equine cadaver limbs, all of which were employed to test the cartilage drilling technique.
  • First, the MCP/MTP joint was distracted using a 5.5-mm cortical screw. After that, the articular cartilage was removed through four stab incisions using a 4.5-mm drill.
  • Certain limbs were then randomly selected to be tested for the minimally invasive application of a tension band using a custom-made cannula.
  • The appropriate positioning of the tension band was confirmed using radiographic imaging.
  • In order to assess and measure the cartilage removal areas, all MCP/MTP joints were disarticulated. This was achieved through a process known as planimetry.

Results

  • For the metacarpus/metatarsus surface, the average percentage of cartilage removal was estimated to be around 66.8% ± 7.6%, 67.9% ± 8.6% for the proximal phalanx surface, and 59.5% ± 1% for the two sesamoid bones.
  • By using the cannula, the tension band could be accurately placed through four stab incisions.

Conclusions

  • The research concludes that the minimally invasive technique for cartilage removal proved to be efficient and it might be beneficial for joint fusion in certain clinical situations.
  • The minimally invasive application of the tension band through stab incisions was also found to be feasible and repeatable.
  • These procedures may allow a complete minimally invasive MCP/MTP arthrodesis to be performed and could be applied in selected clinical cases.
