Variations in the course and distribution of common palmar digital nerves and arteries are rare. A classic common palmar digital nerves and arteries are defined as concomitant. During routine dissection classes to undergraduate medical students we observed formation of each common palmar digital nerve divided into 2 or 3 branches and formed a ring enclosing the corresponding common palmar digit...

The digital nerves to the thumb and index finger have been studied by dissecting twenty-five embalmed upper limbs. The palmar digital nerves to the thumb were constant in position and course, with a short lateral cutaneous branch from the radial palmar digital nerve in 30 per cent of cases. The palmar digital nerves to the index finger had a variable pattern, the commonest arrangement, well des...

Objective- To determine if the pain of the third phalanx due to sidebone fracture in horses can be attenuated by analgesia of the distal interphlangeal joint and palmar digital nerve block. Design- Clinical study. Animals- Seven horses with unilateral forelimb lameness associated with hoof pain due to sidebone fracture. Procedures- Seven mix breed show jumping horses were selected from hor...

During routine cadaveric dissection a female cadaver presented rare combination of neurovascular variations. Persistent axis artery with number of anomalous communicating vessels including vas aberrans connecting brachial and radial arteries were observed in right arm. In the left arm, variations in the formation of median and musculocutaneous nerves, high division of common palmar digital nerv...

Trigger finger is a common disease, and operative treatments are often applied for it. Digital nerve injury is one of the complications of this surgical treatment, and paresthesia and sensory disturbance occur early after the operation. This paper presents a case of trigger finger appearing gradually as increasing digital nerve disorder after surgical treatment. In the second surgery, scar tiss...

Digital neural loops were identified over a century ago and are common findings in cadaveric studies of palmar and digital anatomy. Symptomatic digital neural loops are rare. We report a case of hemidigital anesthesia resulting from a proper digital nerve neural loop penetrated by its common digital artery in the palm. After neurolysis of the median nerve and the common and proper digital nerve...

The blood supply for the synovial tendon sheaths of the hand was carefully investigated. We show that the origin of those arteries, supplying the synovial tendon-sheaths of the Mm. flexor pollicis longus, flexor digitorum superficialis and profundus, lies in the Canalis carpi. We also describe that the branches of the Aa. digitales palmares propriae arise independently. We emphasize that the te...

In an anatomic study of 64 fingers, we demonstrated that the proximal interphalangeal joint is innervated by branches of the palmar digital nerves. The number of articular branches ranges from two to four and their origins from the digital nerve are between 2 and 8 mm from the proximal interphalangeal joint. In a clinical series of 24 neurectomies in 21 patients, there was a significant improve...
