Gross anatomical, computed tomographic and magnetic resonance imaging study of the metacarpo/metatarsophalangeal joint in Egyptian buffalo(Bubalus bubalis)

Abstract

The current study aimed to describe the normal gross anatomy, computed tomography (CT) and magnetic resonance imaging (MRI) of the metacarpo/metatarsophalangeal (MCP/MTP) joint in Egyptian buffalo, and to determine the site of intra‐articular injection of this joint. This study was conducted on eighteen fresh cadaveric distal limbs of healthy Egyptian buffaloes. Six cadaveric MCP/MTP joints were freshly dissected for studying their normal morphological features and determination of the suitable site for intra‐articular injection. Another twelve MCP/MTP joints were imaged using a 16‐slice CT scanner and a 1.5 Tesla MRI scanner, injected with coloured latex and then sectioned into dorsal, sagittal and transverse slices. The articular surface, joint cavity, ligaments and surrounding tendons of the MCP/MTP joint were identified and briefly described. CT and MRI provided identification of the bony and soft tissue structures of the MCP/MTP joint with variable signal intensities. The present study provided a brief description of the normal gross anatomy of MCP/MTP joint in buffalo to serve as a reference for the evaluation of CT and MRI images, which in turn could enable the veterinary clinicians in interpretation of the clinical diseases in this joint.

Gross anatomy, computed tomography, magnetic resonance imaging and bone mineral densitometry of the ovine metacarpo/metatarsophalangeal joint

“…In the present study, CT scans and MRI images provided the possibility of simultaneous observation of bone and soft structures without overlapping soft tissues. This result is consistent with the observations of the other researchers in horses (Kraft & Gavin, 2001), cattle (Hagag & Tawfiek, 2018), camels (Ibrahim et al, 2019) and buffalo (Abdel Maksoud, 2021). In addition, 3D imaging of normal anatomical structures by CT scan and MRI can help to diagnosis orthopaedic disorders (Raji et al, 2009).…”

“…Therefore, Knowledge of the normal descriptive, topographical and cross‐sectional characteristics of anatomical structures in CT scan and MRI is necessary for successful diagnostic image interpretation. These techniques have been used previously for evaluating the metacarpo/metatarsophalangeal joint in the donkey (Amin et al, 2014; El‐Gendy et al, 2020), horse (Hontoir et al, 2014), buffalo (Abdel Maksoud, 2021) and camel (Alsafy et al, 2018). In ovine, Hirtler and Kofler (2014) used of sonography for comparing the metacarpo/metatarsophalangeal joint in sheep and goat and Duncan et al (2013) described the normal radiographic anatomy of this joint in sheep.…”

Intra-articular injection in the hind limb joints of dromedary camels (Camelus dromedarius) using anatomical and arthrographic-guided landmarks

“…A healthy joint is an important structure for the proper movement of the camel limb. Intra-articular (IA) injection is frequently used in veterinary practice for diagnostic and therapeutic purposes and is increasingly used for the early diagnosis of joint injury [3][4][5][6][7][8]. This technique is easy to perform, cost-effective, and requires no special equipment [9].…”
