Introduction
Patellar Fracture and Dental Anomaly Syndrome (PADS) is a rare orthopaedic syndrome (Langley- Hobbs 2016). It affects cats between 4-month and 8-year-old (mean age 28 months). The cause of this condition is yet to be established (Reyesetal. 2018). Our purpose was to report a case of PADS presented with non-traumatic fracture of the ulna on the left thoracic limb.
Clinical case
A 5-year-old, female, neutered, DSH cat presented with history of 24-hour, non-traumatic, non-weightbearing lameness on the left thoracic limb. The patient had history of non-traumatic, bilateral, sectional fractures on the patellae and non-traumatic, transverse fracture on the right femoral diaphysis, at the age of 5 months. Radiographic views confirmed sort-oblique fracture on the central-third of left ulnar diaphysis, increased radiopacity and cortical thickening. Non-formation of dental arcades with only incomplete formation of some teeth was also observed.
Results
Ulnar fracture was addressed with use of 2mm 7-hole plate and 2mm screws. Orthopaedic implants placed in the past on the pelvic limbs were removed at the same time. Fracture healing and return to normal activity was achieved 6 weeks postoperatively.
Conclusions
Diagnosis of PADS is based on evaluating all clinical signs (non-traumatic fracture, increased radiopacity and observations (dental anomalies), including accurate history (early age patellae fractures and past non-traumatic fractures) (Reyes 2018, Langley- Hobbs 2016, Langley-Hobbs 2009). Failing to identify clinical importance of findings could lead to misdiagnosis, inappropriate fracture fixation planning, and incomplete prognosis, of possible future risk of fractures, on these patients (Reyes 2018, Langley- Hobbs 2009).
