A relatively thick (diameter approximately 2 mm), ropelike (length ca. 20 mm) and elastic "Vinculum tendinis" connects--within the fetlock tendon sheath--the dorsal side of the deep digital flexor tendon with the dorsal part of the Manica flexoria (the communicating band of the Musculus interosseous medius to the superficial digital flexor tendon). The extensive fetlock tendon sheath can be involved in diseases such as aseptic and septic inflammations. Spreading of these inflammations makes in some of these cases the partial resection of the tendon of the deep digital flexor muscle and the cutting of these Vincula necessary. The results of this contribution, collected from 60 hindlimbs of adult bovines show variations in number, length, diameter and extent and the inner structure with blood vessels and nerves.

Injury to the palmar supporting structures of the fetlock alters limb stiffness and fetlock angle.

Equine Referral Hospital, Royal Veterinary College, Hertfordshire, UK.
Background: In vivo measurement of limb stiffness and conformation provides a non-invasive proxy assessment of superficial digital flexor tendon (SDFT) and suspensory ligament (SL) function. Here, we compared it in fore and hindlimbs and after injury.
Objectives: To compare the limb stiffness and conformation in forelimbs and hindlimbs, changes with age, and following injury to the SDFT and SL.

Article Synopsis
- This study used cone beam computed tomography (CBCT) to explore the anatomy of the metacarpophalangeal (MCP) and metatarsophalangeal (MTP) joints in healthy horses, involving scans of 15 forelimbs and 14 hindlimbs from nine adult horses.
- After a contrast medium was injected, the limbs were frozen and sectioned to correlate anatomical structures with CBCT images.
- The study found CBCT effective for visualizing bone and certain soft tissue components in the fetlock region, though some ligaments weren't clearly identified, offering a reference for future examinations of horse joints.

University of Liverpool, Department of Equine Clinical Studies, Neston, UK.
Objective: To determine the outcome of tenoscopically guided palmar/plantar annular ligament (PAL) desmotomy to treat PAL constriction without concurrent intrathecal soft-tissue injury, notably of the digital flexor tendons and manica flexoria.
Study Design: Retrospective multicenter cohort study.
Animals: Sixty-five horses.

Department of Anatomy and Embryology, Faculty of Veterinary Medicine, Alexandria University, Abees 10th, Alexandria, Egypt.
Background: The 3D computed tomography produces detailed images of the digit bones in addition to the angiograph render volume 3D of the CT shows the relation between the arteries, bones, and tissues of the digit. Therefore, the present study used those imaging techniques to provide a complete description of the digit bones and arteries' origin, distribution, and course and their relations with surrounding structures in the Dromedary Camel. Which would serve as a guide for surgeons and students in distinguishing normal digit structures.

Objectives: This study aimed to investigate the prevalence and pattern of congenital flexural deformity (knuckling), to identify the association between trace elements and vitamins with the deformity, and to apply different surgical techniques for correcting this congenital malformation in newborn bovine calves.
Materials And Methods: The study was implemented on 17 newborn calves with carpal (knee) and fetlock (foot) knuckling presented to the Veterinary Teaching Hospital of Bangladesh Agricultural University, Mymensingh, from January to December 2020. The serum biochemical alterations and clinical outcomes were assessed on days 0 and 21 following surgery.
