Background and Aim: Bilateral sacroiliac joint luxation, a condition primarily observed in cats, can significantly impact their quality of life. This study aimed to compare a control with three distinct fixation methods to identify the most robust fixation method capable of withstanding significant tensile stress. Materials and Methods: Twenty pelvic bone models of cats were made using a 3D printer with polylactic acid plastic. Each model was assembled by cutting the sacroiliac joints and pelvic girdle symphysis with a handsaw, then bonded with cyanoacrylate glue. 3D feline pelvic bone models were categorized into four significant groups, each consisting of five models. The study discovered that the three groups used distinct fixation methods: Two lag screws (DS), K-wires at the ilium wing and sacroiliac joints (TK), and K-wires at the sacroiliac joints (DK). The final group, not fixed, was the control. Results: The results were characterized further through a mechanical compression force test using a universal testing machine. The most robust method at the sacroiliac joints, the DK technique, sustained a maximum force of up to 183.86 N while maintaining the correct bone alignment. The fixation method is more accessible and faster to implement in comparison to the DS method. Conclusions: The DK group exhibited the greatest maximum load capacity among all groups. Sacroiliac joint luxation treatment can effectively be addressed using the K-wires fixation method. However, the DK need space of sacral body same as DS for fixation. Further clinical study should be performed.

Characterization and comparison of fractures caused by non-accidental injury and road traffic accident in cats

Complex regional pain syndrome (CRPS) is a chronic pain condition that may occur after injury or trauma to a limb. The underlying pathophysiology of CRPS is largely undetermined, although CRPS patients commonly present with a persisting inflammatory response in the early stage of the condition and overexpress the α-1 adrenergic receptor (α-1AR) on nociceptors and keratinocytes in the affected limb. In other chronic inflammatory conditions, increased α-1AR mRNA expression in peripheral blood mononuclear cells (PBMCs) has been shown, and is thought to contribute to persisting inflammation. The α-1AR are expressed on a range of cells, including nerve, smooth muscle, skin and immune cells, and bind to adrenaline and noradrenaline released after activation of the sympathetic nervous system. The aims of this project were to examine the mRNA expression of α-1AR subtypes (α-1A, α-1B and α-1D) by qPCR in PBMCs isolated from fractionated blood of CRPS patients, and to quantify the percentages of various PBMC subpopulations compared to healthy controls. Subpopulations of PBMCs were determined by flow cytometry using a panel of fluorescent antibodies that identified CD4+ T cells, CD8+ T cells, CD4+ CD8+ T cells, CD4+ CD25+ T cells, CD8+ CD25+ T cells, B cells, natural killer (NK) cells, NKT cells, and subsets of monocytes. No differences in expression of α- 1AR subtypes in PBMCs of CRPS patients were found when compared to healthy controls. However, a significant increase in the concentration of total PBMCs isolated per mL of blood in CRPS patients and a shift from CD16- to CD16+ monocyte subpopulations was identified when compared to healthy controls. These results show there is an inflammatory component to CRPS and provide preliminary evidence that the persisting inflammation in CRPS patients may originate from over-proliferation of PBMC progenitors in the bone marrow, which is sympathetically modulated by α-1AR, and/or an expansion of other PBMC cell types that were not examined in this project.
