Assessment of acetabular cup positioning from a lateral radiographic projection after total hip replacement.

Objective: To demonstrate first that a ventrodorsal radiographic (VDR) projection is inadequate for obtaining accurate acetabular cup position (ACP) measurements after total hip replacement (THR), and second to validate use of the lateral radiographic (LR) projection to measure ACP.

Study Design: In vitro study.

Methods: Eleven VDRs were obtained after insertion of a cup into the acetabulum of a Sawbones pelvis fixed at an approximated angle.

Successful management of a dog that had severe rhabdomyolysis with myocardial and respiratory failure.

CASE DESCRIPTION - A 6-year-old castrated male Llewelyn Setter was evaluated because of an acute onset of myalgia and respiratory distress. CLINICAL FINDINGS - Physical examination revealed a stiff stilted gait, swollen muscles that appeared to cause signs of pain, panting, and ptyalism. The dog had a decrease in palpebral reflexes bilaterally and a decrease in myotatic reflexes in all 4 limbs.
