Comparison of limited-contact dynamic compression plate and locking compression plate constructs for proximal interphalangeal joint arthrodesis in the horse.

Abstract: This study compared in vitro monotonic and cyclic mechanical properties of equine proximal interphalangeal joint arthrodeses stabilized using an open or closed technique combined with axial 4.5 mm narrow limited-contact dynamic compression plate (LC-DCP) or 4.5 mm narrow locking compression plate (LCP). Ten forelimb pairs were randomly assigned to LCP or LC-DCP groups. One limb in each pair was assigned to either open or closed technique. Limbs were tested for cyclic fatigue at 20 000 cycles and then single-cycle to failure under 3-point dorsopalmar bending. There was no significant difference in stiffness of constructs during cyclic fatigue testing or on force or stiffness at failure in single cycle to failure testing between open and closed techniques or between plate types. Both implants, surgical technique, or combinations thereof are suitable for clinical use. More work is necessary to define the interaction between implant type and surgical technique. Comparaison des constructions de plaques de compression dynamique à contact limité et de plaques de compression à verrouillage pour l’arthrodèse de l’articulation interphalangienne proximale chez les chevaux. Cette étude a comparé les propriétés mécaniques monotoniques et cycliques in vitro des arthrodèses interphalangiennes proximales équines stabilisées à l’aide d’une technique ouverte ou fermée combinée à une plaque de compression dynamique axiale étroite à contact limité de 4,5 mm (LC-DCP) ou à une plaque de compression étroite à verrouillage de 4,5 mm (LCP). Dix paires de pattes avant ont été assignées au hasard à des groupes LCP ou LC-DCP. Une patte de chaque paire était assignée soit à la technique ouverte ou fermée. Les pattes ont été évaluées pour la fatigue cyclique à 20 000 cycles, puis à un cycle unique jusqu’à l’échec à l’aide d’une flexion dorsopalmaire à 3 points. Il n’y avait pas de différence significative dans la rigidité des constructions durant l’évaluation de fatigue cyclique ou sur la force ou la rigidité à l’échec durant l’évaluation dans un cycle unique jusqu’à l’échec entre les techniques ouvertes et fermées ou entre les types de plaques. Les deux implants, techniques chirurgicales ou une combinaison des deux sont appropriés à l’usage clinique. Il est nécessaire d’effectuer des recherches additionnelles pour définir l’interaction entre le type d’implant et la technique chirurgicale.(Traduit par Isabelle Vallières).

This research compares two techniques for stabilizing horse limb joints using different types of plates, finding no significant difference between the methods. The implications for horse surgery are explored further in the paper.

Research Objective

This research study aimed to compare limited-contact dynamic compression plates (LC-DCP) and locking compression plates (LCP) for horse limb joint stabilization. Two surgical techniques, open and closed methods, were tested in vitro using pairs of equine forelimbs. The study wanted to measure the monotonic and cyclic mechanical properties of equine proximal interphalangeal joint arthrodeses – surgical fixation of the joint.

Methodology

  • 20 limbs (10 pairs) were divided randomly into two groups, assigned to LC-DCP and LCP plates.
  • Within each pair, one limb was assigned the open surgical technique and the other the closed technique.
  • Limb pairs were put through cycles of strain to simulate conditions after surgery, specifically 3-point bending.
  • Cyclic fatigue was tested at 20,000 cycles, and then a single-cycle was run to the point of breaking.

Results

  • Stiffness of constructs during cyclic fatigue testing found no significant difference between open and closed techniques or types of plates (LC-DCP vs LCP).
  • No significant difference on force or stiffness at failure point in the single-cycle test between techniques or plate types.

Conclusions

  • The results indicate that both types of plates (L-DCP and LCP) and surgical techniques (open and closed) are suitable for clinical use in equine medicine.
  • It was noted that further research is needed to understand the interaction between the choice of implant and surgical technique better.
