Arthroscopic exploration of ventromedial part of canine coxofemoral joint is limited in conventional dorsal approach.
We evaluated the efficacy of a medial arthroscopic approach to the coxofemoral joint of dogs by analyzing the joint visible area and performing a safety analysis.
Arthroscopic approaches to the coxofemoral joint were made in five cadavers using a traditional (dorsal) and novel (medial) approach. Three observers scored the visible area of images and videos of the acetabulum and femur. A safety analysis was performed via dissection of the medial hind limb. The distance between neurovascular structures and arthroscopic portals was measured.
The acetabulum was more visible in the dorsal than in the medial approach, with mean visualization scores of 16 ± 0.00 and 11.83 ± 1.26, respectively. The medioventral side of the femur was significantly more visible in the medial than in the dorsal approach, with mean visualization scores of 3.9 ± 0.99 and 6.93 ± 0.58, respectively. Safety analysis confirmed the medial portal site was safe, provided that the surgeon has comprehensive knowledge of the joint. The minimum distance from the arthroscopic medial portals to the nearest neurovascular structures was 2.5 mm.
A medial arthroscopic approach to the canine coxofemoral joint has potential clinical application. Dorsal and medial approaches differ significantly and have distinct purposes. The medial approach is useful to access the ventromedial joint, making it an eligible diagnostic method for an arthroscopic evaluation of this area.
在传统的背侧入路中，对犬髋关节腹侧的关节镜探查受到限制。
通过分析关节可见区域并进行安全性分析，评估犬髋关节的内侧关节镜入路的效果。
在 5 具尸体上使用传统（背侧）和新的（内侧）入路进行髋关节镜检查。3 名观察者对髋臼和股骨的图像和视频的可见区域进行评分。通过对内侧后肢的解剖进行安全性分析。测量神经血管结构和关节镜入路之间的距离。
背侧入路时髋臼的可视性优于内侧入路，平均可视评分分别为 16 ± 0.00 和 11.83 ± 1.26。股骨的中-腹侧在内侧入路时比在背侧入路时更可见，平均可视评分分别为 3.9 ± 0.99 和 6.93 ± 0.58。安全性分析证实内侧入路的位置是安全的，前提是外科医生对关节有全面的了解。从关节镜内侧入路到最近的神经血管结构的最小距离为 2.5 毫米。
犬髋关节的内侧关节镜入路具有潜在的临床应用价值。背侧和内侧入路有明显的不同，具有不同的用途。内侧入路可用于接近关节的腹侧，是对该区域进行关节镜评估的一种合适的诊断方法。
