Case summary: A 1-year-old spayed female domestic shorthair cat presented for evaluation of a non-weight bearing right pelvic limb lameness after falling from a 4 m height. On orthopedic examination there was substantial swelling and pain on manipulation of the right pes. Radiographs were obtained under sedation, and these revealed dorsoproximal luxations of the third, fourth and fifth metatarsophalangeal joints, and lateral rotation of the second digit.

Coxofemoral luxation is the most common type of joint luxation observed clinically in dogs.

This retrospective study determines the complications and outcomes of open reduction and internal fixation of coxofemoral luxations using a toggle rod stabilization in 58 dogs. The purpose of the study was to compare the results with previous studies to ascertain commonalities and differences.

OBJECTIVES: The aim of this study was to evaluate outcomes and prognostic factors for cats with sacrocaudal luxation.

Proximal tibial deformities or patellar luxation may occur concurrently with cranial cruciate ligament rupture.

The objective of this study was to describe the management of those conditions with a modified triple tibial osteotomy (TTO) in nine dogs. Medical records of dogs who underwent a modified TTO were reviewed.
