Summary

The HELICA-Endoprosthesis, a new cementless canine hip implant, shows encouraging early results in dogs with hip osteoarthritis. While some complications occurred during the learning phase, most dogs regained weight-bearing ability quickly.

Area of Science:

  • Veterinary Orthopedics
  • Canine Hip Replacement
  • Biomaterials and Implants

Background:

  • Severe hip osteoarthritis and chronic hip luxation significantly impact canine mobility and quality of life.
  • Current treatment options may involve pain management, conservative therapies, or surgical interventions with varying success rates.

Purpose of the Study:

  • To evaluate the early clinical outcomes of the novel HELICA-Endoprosthesis in dogs with hip joint conditions.
  • To assess the safety and efficacy of this cementless hip prosthesis in a canine population.

Main Methods:

  • Implantation of the HELICA-Endoprosthesis (cementless, screw-in femoral stem and acetabular component) in 39 dogs with severe hip osteoarthritis and 1 dog with chronic hip luxation.
  • Patients ranged from 9 months to 10 years old and weighed 22-54 kg.

  • Postoperative monitoring included assessment of weight-bearing, complications, and radiographic findings.

    • Main Results:

    • All dogs were capable of weight-bearing on the operated leg one day post-surgery.
    • Complications included loosening of stem and/or cup components in five dogs, primarily attributed to technical errors during the learning phase.
    • Surgical revisions were successful in three of five cases; two required femoral head and neck excision.
    • Radiographic bone resorption was noted in two dogs without significant clinical lameness.
    • One dog experienced temporary ischial neuropraxy, with complete recovery within six weeks.

    Conclusions:

    • The HELICA-Endoprosthesis offers a potentially simpler surgical technique with shorter surgery times for canine hip replacement.
    • Early clinical results are encouraging, with rapid return to weight-bearing observed.
    • Further long-term follow-up, gait analysis, and histological evaluation are necessary for definitive assessment.
