Background

Shoulder joint dysplasia is a common orthopedic condition in cats.
Intraarticular osseous bodies can cause pain and lameness.

Observation

A 2-year-old Himalayan cat presented with left thoracic limb lameness.
Radiography revealed severe bilateral shoulder joint dysplasia and intraarticular osseous bodies.

Findings

Surgical removal of osseous bodies using arthroscopy (NanoScope) resolved lameness.
Histology confirmed enchondral ossification of the removed bodies.
Recurrence of an osseous body was noted nine months post-surgery, with mild lameness detected by pressure plate gait analysis.

Implications

Arthroscopic removal of intraarticular osseous bodies is an effective treatment for feline shoulder dysplasia.
Close monitoring is recommended due to the potential for recurrence.
Advanced arthroscopic technology offers minimally invasive solutions for complex orthopedic issues in cats.
