“…Regular cyclists, particularly those who receive higher levels of vibration e.g. off road cyclists, are at risk of upper limb co mpression neuropathy [15][16][17][18]. Nerve injury is more frequently seen in the ulnar nerve than the med ian nerve, [19,20] with symptoms including weakness of grip and occasionally numbness of the fourth and fifth fingers [21].…”

Whole body vibration has received much attention as an innovative approach to exercise, lead ing to constantly increasing attention fro m the scientific co mmunity. Previous research considering occupational vibration has illustrated the risks associated with high levels of exposure to vibration; however during vibrat ion exercise the exposure duration is much shorter and therefore the potential comp licat ions must be reconsidered. This review brings together research from various aspects of occupational vibrat ion, clin ical research and vib ration exercise to address issues within the context o f health and safety with a part icular focus on neurophysiological and neurovascular responses. The results indicate that peripheral nerve and blood vessels are exposed to risks such as compression, shear stress and altered function as a response to vibration. However, correct planning and implementation of exercise protocols should effectively control these risks. By summarising the areas that have received attention an overview of potential co mplications will be achieved; with an understanding of which factors prevent participation and those that simp ly require an amended approach to vibration exercise.

“…One of the sites of ulnar nerve compression is a fibroosseous tunnel at the wrist known as Guyon's canal (tunnel, lodge or space). Guyon's canal has also been termed canalis ulnaris, [1] the distal ulnar tunnel, [2] carpal ulnar neurovascular space, [3] pisoretinacular space, [4] or the pisohamate tunnel. [5] It was first described as a space at the base of the hypothenar eminence by the French surgeon Jean Casimir Felix Guyon in 1861 who became interested in a small protrusion on the palmar aspect of his wrist when he applied pressure to the hypothenar eminence.…”

Objectives: Guyon's canal is clinically significant because it contains the ulnar nerve, artery and veins and is a location for compression injury. This study was undertaken to determine the anatomy of the ulnar nerve in Guyon's canal on 40 wrists of 20 adult formalin-fixed cadavers.Methods: 40 wrists of 20 formalin-fixed adult cadavers obtained from the Department of Anatomy, Ege University Faculty of Medicine were dissected. In each cadaver, the skin and the subcutaneous fatty tissues were removed starting from the forearm down to the palm of the hand. The palmaris brevis muscle and the palmar aponeurosis were dissected to expose Guyon's canal. Results:The length and diameter of the main trunk of the ulnar nerve in Guyon's canal before dividing into its terminal branches were measured as 11.72±1.99 mm and 3.41±0.5 mm, consequently. Within the canal, the main trunk divided into two terminal branches. The diameter of the deep branch was 1.77±0.47 mm and the superficial branch was 2.41±0.45 mm. The superficial branch divided into the proper palmar digital nerve supplying the medial side of the little finger and the common palmar digital nerve supplying the adjoining sides of little and ring fingers. Conclusion:An accessory abductor digiti minimi muscle was observed as a possible cause of compression in Guyon's canal. Despite its clinical relevance, the diameters of the deep and superficial branches of the ulnar nerve in Guyon's canal do not exist in previous studies.

Ulnar Neuropathy in Bicycle Riders

Abstract: Three patients, one of whom is described in detail, developed ulnar neuropathy following prolonged bicycle riding, with compression of the ulnar nerve at the level of the ulnar canal at the wrist.
