Summary
The purpose of this study was to investigate the long-term treatment results of fragmented
coronoid process (FCP) in joints with a radio-ulnar step greater than 3 mm. Treatment
of these patients only consisted of fragment removal, without correction of the incongruity.
The eight Bernese Mountain Dogs (11 joints) included in this study showed obvious
clinical signs of elbow disease and were diagnosed with severe elbow incongruity and
concomitant FCP in the time period from 1999–2003. At that time, elbow radiography,
computed tomography, and arthroscopy were performed. The mean follow-up period was
5.6 years. The follow-up consisted of a telephone questionnaire combined with a clinical
and radiographic re-evaluation at our clinic.
The questionnaire revealed that all dogs were either free of lameness or only lame
following heavy exercise. One dog sporadically required medication after heavy exercise.
The owner satisfaction rate was 100%. The clinical re-evaluation did not reveal any
signs of pain or lameness in all cases. Range-of- motion was decreased in nine of
the 11 elbows. Radiographs revealed an increase in severity of osteoarthritis in every
case.
In this case series, arthroscopic fragment removal without treatment of incongruity
was demonstrated to be a valuable treatment option and may provide a satisfactory
long-term outcome.
