Development of a Novel Medial Synoviocentesis Approach to the Bicipital Bursa in an Equine Cadaver Model.
Abstract: To describe the volume and dimensions of the bicipital bursa and its position in relation to bony and soft tissue structures, in order to develop a novel medial synoviocentesis approach to the bicipital bursa. Methods: Cadaveric study. Methods: Adult equine cadaver limbs (n=19). Methods: Bicipital bursa dimensions, volume, and relationship to bony structures were obtained from positive contrast computed tomography images after distension of the bursa (n=7). Following an intra-bursal injection of polyurethane resin, the bicipital bursa (n=4) was dissected and its relationship to soft tissue structures described. After computed tomography and dissection, a novel medial bicipital bursocentesis approach was investigated on intact cadavers (n=8). Results: Median (range) of measurements were: length 9.02 cm (8.48-9.45 cm); width 7.06 cm (6.71-8.01 cm); and volume 51 mL (45-58 mL). The medial aspect of the bicipital bursa was located at the junction of the subclavius and biceps muscles, which corresponds with the externally visible lateral pectoral sulcus. Needle insertion 5-10 mm craniolateral to the center of the lateral pectoral sulcus midway between the palpable distal aspect of the deltoid tuberosity and the cranial part of the greater tubercle was found to be a reliable landmark for the novel medial bursocentesis approach. This approach was successful in all cadavers. Conclusions: The novel approach to the bicipital bursa provided access to the medial aspect of the bursa and is an alternative to the lateral approaches. Further validation in live horses is warranted to establish the safety and efficacy of this technique.

This research study discusses a newly devised method of accessing the bicipital bursa (a sac that reduces friction in horse limbs) through a medial synoviocentesis approach in horses, which has been tested using an equine cadaver model.
Research Methodology
- The research was conducted through a cadaveric study using adult equine cadaver limbs (total 19).
- Initially, dimensions, volume, and the spatial relationship of the bicipital bursa to bony structures were extracted from positive contrast computed tomography (CT) images after inflating the bursa.
- Likewise, following an injection of polyurethane resin inside the bursa, the bicipital bursa was dissected and its relationship to soft tissue structures was described.
- Post CT imaging and dissection phases, a new medial bicipital bursocentesis approach was tested on the intact cadavers.
Research Findings
- Data like length, width, and volume of the bicipital bursa were obtained, with median measurements standing at 9.02 cm (range: 8.48-9.45 cm), 7.06 cm (range: 6.71-8.01 cm), and 51 mL (range: 45-58 mL) respectively.
- The medial aspect of the bicipital bursa was determined at the junction of the subclavius and biceps muscles, which aligns with the externally visible lateral pectoral sulcus.
- A reliable landmark for the new medial bursocentesis approach was discovered. A needle inserted 5-10 mm craniolateral to the center of the lateral pectoral sulcus midway between the palpable distal aspect of the deltoid tuberosity and the cranial part of the greater tubercle was found to be successful.
- All cadavers positively responded to this new approach.
Conclusion
- The research concludes that this new approach to the bicipital bursa proves to access the medial aspect of the bursa and can be an alternative to the existing lateral approaches.
- The authors suggest that further validation in live horses is necessary to confirm the safety and effectiveness of this technique.
