Osseous sequestration is an orthopedic disorder increasingly recognized in camelids (alpacas and llamas).1 Clinical data regarding sequestra in camelids have been limited to publication in conference proceedings1,2,a or individual case reports.3,4 The clinical manifestation of sequestra in affected camelids contrasts with that in other large animal species, such as cattle and horses, because the condition has only been reported in camelids < 2 years of age and most often develops without evidence of trauma.1–4,a Sequestration of bone in camelids is proposed to be a sequela of hematogenous osteomyelitis.3–4,a To the authors' knowledge, no studies have been conducted to characterize the clinical signs, diagnosis, treatment, and long-term outcome in a large number of alpacas and llamas with bone sequestra.
The objectives of the study reported here were to characterize the history, clinical signs, treatment, complications, and outcome of sequestra in alpacas and llamas. On the basis of clinical experience, we hypothesized that sequestra in camelids would be most commonly associated with etiologies other than trauma and with juvenile (< 2 years old) alpacas and llamas. We also hypothesized that sequestrectomy would be a successful procedure with few complications when performed in affected alpacas and llamas.
