Feline patella fracture and retained deciduous teeth syndrome is a condition which has only relatively recently been recognised in cats. In this syndrome affected cats develop fractures of the patella (knee cap) without any obvious inciting cause such as trauma. In addition affected cats frequently go on to develop fractures in other bones, again without any apparent cause. The other bones most commonly involved are the tibia (shin bone), humerus (upper arm) and ishium (part of the pelvis). In addition to bony problems, affected cats commonly also have retained deciduous (baby) teeth. A finding that is normally rare in cats.
Repair of the patella fractures can frequently be challenging with many cases failing to achieve a radiographic union though many will do well clinically even if the repair fails.
A study group has been set up at the University of Bristol headed by Professor Sorrel Langley-Hobbs MA BVetMed DSAS(O) DECVS FHEA MRCVS to investigate the condition. This study will look at many aspects of the disease including bone density, strength and collagen analysis. One possible theory as to the cause of feline patella fracture syndrome is that this may be a manifestation of osteogenesis imperfecta – a disease which causes brittle bones. There are however a number of disease processes which can result in bone fragility and therefore further study is needed to identify factors involved in these cases. A few case reports of suspected feline osteogenesis imperfecta exist in the literature but none of these cases have been confirmed. We aim to investigate cases of feline patella fracture syndrome to identify if these are a form of OI or to see if alternative causes can be identified.
If you cat has been diagnosed with this condition*, or you are a vet and see a case of feline patella fracture retained deciduous teeth syndrome, then we would grateful if you could fill out the following survey. It should only take 5 minutes and will be very useful for our study.
*For owners, please fill out as much as you can and then ask your vet to complete any remaining sections.
