Le Docteur Maëlle Farfan est diplômée de l’Ecole Nationale Vétérinaire de Lyon en 2014. Elle a réalisé un assistanat à la Clinique de Grosbois puis après 1 an de pratique libérale supplémentaire, elle a rejoint la clinique pour une résidence en chirurgie auprès du Docteur Rossignol.
Maëlle Farfan a complété les 3 années que dure cette formation et elle se prépare à passer l’examen qui lui permettra donc de détenir le diplôme de spécialiste en chirurgie dénommé « ECVS » (European College of Veterinary Surgery).
Farfan M, Genton M, Rossignol F. Ex vivo study of minimally invasive procedures for cartilage removal from the metacarpophalangeal or metatarsophalangeal joint and for fetlock tension band application. Veterinary Surgery. 2020;1–9.
Objective: 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.
Study design: Experimental study.
Sample population: 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 ran- domly chosen limbs were then tested for minimally invasive tension band appli- cation 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 sur- face, and 59.5% ± 1% for the two sesamoid bones. The tension band could be accurately placed through four stab incisions with the cannula.
Conclusion: This minimally invasive technique for cartilage removal was effi- cient and should be favorable for joint fusion in some clinical situations. The minimally invasive tension band application through stab incisions was feasi- ble and repeatable.
Clinical significance: These procedures should allow total minimally invasive MCP/MTP arthrodesis and be used in selected clinical cases.
