Summary

Cementless total hip replacement (THR) successfully managed chronic slipped capital femoral epiphysis (SCFE) in an alpaca, significantly improving lameness and hip function. This innovative approach offers a potential solution for similar orthopedic conditions in camelids.

Area of Science:

  • Veterinary Orthopedics
  • Comparative Medicine
  • Surgical Innovation

Background:

  • Slipped capital femoral epiphysis (SCFE) is a developmental disorder affecting the hip joint.
  • Chronic SCFE can lead to secondary osteoarthritis and significant lameness in camelids.
  • Limited treatment options exist for chronic SCFE in alpacas.

Observation:

  • A case report details the management of an 18-month-old, 47 kg male alpaca with chronic right SCFE and secondary osteoarthritis.
  • The alpaca underwent cementless total hip replacement (THR) using a canine prosthesis.
  • Pre- and post-operative assessments included clinical evaluation, radiography, and force plate gait analysis.

Findings:

  • Cementless THR resulted in marked improvements in the alpaca's comfort, lameness, and range of motion.

Surgical Technique of the 3-Dimensional-printed Personalized Hip Implant for the Treatment of Canine Hip Dysplasia

Published on: April 19, 2024

  • Preoperative gait analysis showed decreased contact time and vertical impulse in the affected limb.
  • Postoperative gait analysis at 8 weeks revealed no significant differences between pelvic limbs, indicating restored function.

    • Implications:

    • Total hip replacement (THR) effectively restored hip function in an alpaca suffering from coxofemoral osteoarthritis secondary to chronic SCFE.
    • Cementless THR using a canine prosthesis is a viable treatment for selected degenerative and traumatic coxofemoral joint conditions in alpacas.
    • This case highlights the potential of advanced orthopedic procedures in managing complex conditions in non-domesticated species.
