The present study was conducted on eight fresh forelimbs to investigate a detailed anatomical description of the arterial blood supply in adult dromedary camel’s foot. Anatomical and angiographic techniques were used in order to give detailed data about the origin and pattern of distribution of these arteries. Moreover, this data serve other researchers in comparison with different animals. The specimens injected with red colored gum milk latex for anatomical dissection and urograffin injection for angiographic purposes throughout the median artery. The main arterial blood supply of camel’s digit was derived from common palmar digital artery, palmar metacarpal artery, in addition to smaller branches detached from the dorsal metacarpal artery.

To investigate the normal anatomical distribution of the arterial blood supply, venous drainage and innervation on both the dorsal and plantar aspects of pes region including the level of tarsal joint due to its clinical importance with a little data available. Methods: Ten hind paws of five adult apparently healthy domestic dogs of both sexes; six paws injected, through blood vessels with colored latex neoprene for anatomical dissection and the other four paws injected a contrast mixture of red lead oxide and turpentine oil for the radiographic investigation of blood vessels. In addition to five live dogs used to apply the distal limb local anesthesia with the aid of Needle-Guided Ultrasonography. Results: This investigation revealed that the dorsal and plantar aspects of dog pes region supplied by superficial and deep sets of arteries, veins and nerves. The three dorsal metatarsal arteries originated from the arcuate artery. The medial tarsal vein forming characteristic venous arcades. The 3rd plantar metatarsal artery divided into two axial arteries while the 2nd and 4th continued axially without division. The plantar common digital and metatarsal nerves II, III, IV communicated to give origins of the axial and abaxial plantar proper digital nerves except the abaxials of the 2nd and 5th digits which supplied by a branch from medial plantar nerve and lateral plantar nerve respectively. Conclusion: There were little differences between dogs and other carnivores in vascularization of hind paw with the recommendation of using Needle-Guided Ultrasonography in the distal limb local anesthesia to avoid vascular puncture or damage.

Flexor Digitorum

Background: The transfer of flexor-to-extensor is widely used to correct lesser toe deformity and joint instability. The flexor digitorum longus tendon (FDLT) is percutaneously transected at the distal end and then routed dorsally to the proximal phalanx. The transected tendon must have enough mobility and length for the transfer. The purpose of this study was to dissect the distal end of FDLT and identify the optimal technique to percutaneously release FDLT. Methods: Eight fresh adult forefoot specimens were dissected to describe the relationship between the tendon and the neurovascular bundle and measure the width and length of the distal end of FDLT. Another 7 specimens were used to create the percutaneous release model and test the strength required to pull out FDLT proximally. The tendons were randomly released at the base of the distal phalanx (BDP), the space of the distal interphalangeal joint (SDIP), and the neck of the middle phalanx (NMP). Results: At the distal interphalangeal (DIP) joint, the neurovascular bundle begins to migrate toward the center of the toe and branches off toward the center of the toe belly. The distal end of FDLT can be divided into 3 parts: the distal phalanx part (DPP), the capsule part (CP), and the middle phalanx part (MPP). There was a significant difference in width and length among the 3 parts. The strength required to pull out FDLT proximally was about 168, 96, and 20 N, respectively, for BDP, SDIP, and NMP. Conclusion: The distal end of FDLT can be anatomically described at 3 locations: DPP, CP, and MPP. The tight vinculum brevis and the distal capsule are strong enough to resist proximal retraction. Percutaneous release at NMP can be performed safely and effectively. Clinical Relevance: Percutaneous release at NMP can be performed safely and effectively during flexor-to-extensor transfer.

AbstractThe coexistence of different muscular-neurovascular variations is of significant clinical importance. A male cadaver, 76 years old at death, was subjected to routine anatomical dissection; the procedure was performed for research and teaching purposes at the Department of Anatomical Dissection and Donation, Medical University of Lodz. The right forearm and hand were dissected using standard techniques according to a strictly specified protocol. The presence accessory head of the flexor pollicis longus may potentially compress the anterior interosseous nerve. The present case report describes a rare variant of the ulnar head of the pronator teres, characterized by two independent bands (i.e., two proximal attachments). The main band originates from the coronoid process and the second originates from the tendon of the biceps brachii. This type of attachment could potentially affect the compression of the ulnar artery running between the two bands. Additionally, the accessory head of the flexor pollicis longus was observed, which started on the medial epicondyle; its coexistence with a high division median nerve creates a potential pressure site on the anterior interesosseous nerve.
