Anesthesia was induced, and lumbosacral subarachnoid analgesia or epidural anesthesia was performed in the kangaroos. All cases received anti-inflammatory, analgesic, and antibiotic therapies peri- and postoperatively. A craniolateral surgical approach was made over the coxofemoral joint as in canine patients. Open reduction was performed and a TightRope® system was placed. Postoperative radiographs confirmed joint reduction and appropriate implant position. One kangaroo developed postoperative subcutaneous edema of the distal ipsilateral limb, which resolved with supportive therapies. Exercise restriction was instituted in all cases for 6–8 weeks before gradually increasing activity. The wallaby re-presented 4 months later for a right subtrochanteric femoral fracture.

There is minimal knowledge known on the analyte breakdown of this or closely related species. As this species becomes more popular in the exotic community more medical conditions are being identified that can be assisted in diagnosis with the establishment of ranges of the different essential analytes. Being an insectivorous lizard, this species may suffer from hypovitaminosis A. There has been a lack of antemortem diagnostics available for minimally invasive and appropriate diagnosis of this disease. Recent studies have been performed in other small insectivore species establishing plasma retinol reference intervals. Reference intervals for retinol have not been published or validated in collared lizards or any closely related species.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;Plasma, with a sample volume of only 50 µl, from forty clinically healthy captive bred Eastern collared lizards, twenty males and twenty females were analyzed using ultra-high-performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS) to determine plasma retinol concentrations.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;Using UPLC-MS/MS analysis, data was normally distributed and a reference interval for plasma retinol in the Eastern collared lizard was 1.57-3.07 µg/mL (0.237-0.464 µmol/L). A mean of 0.31µg/mL; with a lower limit 95% confidence interval being 1.34-1.80 µg/mL and upper limit of 2.84-3.30 µg/mL.

There was only 1 statistical variation seen in age groups between the 1-year-old and 6-year-old age groups with the 6-year-old age group being significantly lower than the 1-year-old age group.

Values are valuable in assistance in diagnosing and treating hypovitaminosis A and to provide advice on dietary supplementation and dietary improvement for the collared lizards and possibly other related species as well.
