Comparison of medial and lateral ultrasound-guided approaches for periarticular injection of the thoracolumbar intervertebral facet joints in horses.
Abstract: To compare ultrasound-guided lateral and medial approaches for periarticular injections of the thoracolumbar intervertebral facet joints (IFJ). Methods: Experimental cadaveric study. Methods: Adult equine cadavers (n=4). Methods: IFJ (T12-T13 to L5-L6) were identified by ultrasound (transducer perpendicular to the spine axis) and insertion of a 13 cm, 18 g spinal needle monitored until bone contact using medial (right side) and lateral (left side) approaches. Number of needle insertions at each site, needle repositioning, and insertion depth were recorded. On bone contact 2 mL latex was injected. Intraarticular deposition, distance of latex from the closest articular margin, and presence of latex in the multifidus muscle were established by dissection. Results: Of 96 attempts, only 1 site require reinsertion of the needle; however, 46% of the injections required needle repositioning. Mean ± SD insertion depth was 8.5 ± 1.1 cm. Most injections (86%) were intraarticular and 96% were at or within 0.5 cm of the closest articular margin. Needle insertion relative to the transducer (lateral, medial) had no effect on the distance from the latex to the closest articular margin and all injections were performed into the multifidus muscle. Conclusions: Ultrasound-guidance facilitated accurate periarticular injection of thoracolumbar IFJ irrespective of using a medial or lateral approach.

This study examined two ultrasound-guided techniques used for injecting the thoracolumbar intervertebral facet joints (IFJ) in horses and found no significant difference in accuracy between medial and lateral approaches.
Objective and Methodology
- The study was conducted as an experimental cadaveric investigation on adult equine cadavers, with the focus being on the thoracolumbar intervertebral facet joints (IFJ) of the spine. The main aim was to compare the effectiveness and accuracy of medial (right side) and lateral (left side) approaches for ultrasound-guided periarticular injection.
- The injection process involved the identification of the IFJ by ultrasound and the insertion of an 18g, 13cm spinal needle, which was monitored until it made contact with the bone. Various factors like the number of needle insertions at each site, the depth of needle insertion, and the necessity of needle repositioning were recorded.
- After each needle reached bone contact, 2mL of latex was injected and then the location of latex deposition, its distance from the nearest articular margin, and its presence in the multifidus muscle were determined via dissection.
Results
- Out of the 96 injection attempts made, only one site required needle reinsertion, implying that the success rate of the initial needle insertion was high. However, repositioning of the needle was needed in about 46% of the total injections.
- The average depth of needle insertion was found to be 8.5 ± 1.1 cm. Additionally, most injections (86%) landed within the joint, while almost all (96%) were at or within 0.5 cm of the nearest articular margin.
- No significant difference in accuracy was found between medial and lateral needle insertions relative to the transducer. Furthermore, all injections ended up in the multifidus muscle.
Conclusion
- The study concluded that ultrasound guidance is an effective tool for accurate periarticular injection of the thoracolumbar IFJ in horses, irrespective of the use of a medial or lateral approach.
