title: Cementless total hip replacement in an alpaca.
abstract: OBJECTIVE
  To report management of a chronic slipped capital femoral epiphysis (SCFE) in an alpaca using cementless total hip replacement (THR).
  
  
  METHODS
  Case report.
  
  
  METHODS
  An 18-month-old, 47 kg alpaca male.
  
  
  METHODS
  Cementless THR was performed in an alpaca with a chronic, right SCFE, and secondary osteoarthritis. Force plate gait analysis was performed before and 8 weeks after surgery. Outcome was determined through clinical evaluation, radiography, and force plate gait analysis.
  
  
  RESULTS
  Cementless THR resulted in marked improvement in the alpaca's comfort level, degree of lameness, and range of motion. On preoperative force plate gait analysis there was decreased contact time (P=.01) and vertical impulse (P<.01) of the affected limb, whereas at 8 weeks postoperatively significant differences in gait analysis between pelvic limbs were not apparent.
  
  
  CONCLUSIONS
  THR using a BioMedtrix canine cementless modular prosthesis restored hip function in an alpaca with coxofemoral osteoarthritis from chronic SCFE.
  
  
  CONCLUSIONS
  THR may be an appropriate treatment for selected traumatic and degenerative conditions of the coxofemoral joint in alpacas.
