What are the fascial spaces of hand?
Deep fascial spaces of the hand. The palm has three potential closed spaces with well defined anatomical borders; the thenar, mid palmar, and the hypothenar space. These spaces are deep to the flexor tendons but superficial to the interosseous muscles.
What is Palmar Aponeurosis?
The Palmar aponeurosis is the central part of the deep fascia of the palm which is a highly specialized thickened structure with little mobility. It is triangular in shape and it covers the underlying neurovascular and tendon structures.
What are pulp spaces?
The pulp spaces are fibrofatty compartments on the palmar side of the distal phalanx of the fingers and thumbs. They contain ramifications of the digital vessels on route to the distal phalanx – obstruction here can precipitate bone necrosis. Each space is lined and divided up by fibrous septa.
What is the first web space?
The first web space is a unique anatomical region of the hand that plays an integral role in the motions of grasp and pinch. It has a triangular shape with its vertex between the first and second metacarpals distal to the carpometacarpal joint and spanning the metacarpal heads.
What are fascial spaces?
Fascial spaces (also termed fascial tissue spaces or tissue spaces) are potential spaces that exist between the fasciae and underlying organs and other tissues. Those containing neurovascular tissue (nerves and blood vessels) may also be termed compartments.
What is flexor pollicis longus?
The flexor pollicis longus (FPL) is a long muscle located at the deep layer with flexor digitorum profundus and pronator quadratus in the anterior compartment of the forearm. Though it is situated at the forearm, it is classified as part of the extrinsic muscles of the hand as it’s function is seen in thumb movement.
What is palmaris longus tendon?
Palmaris longus is the most superficial muscle of the superficial forearm flexors, found deep to the forearm skin. Just proximal to the wrist, the palmaris longus tendon sits medial to that of flexor carpi radialis, and the median nerve passes between the tendons of these two muscles.
What is dorsal and plantar?
Palmar, Dorsal and Plantar The opposite side of your hand, the back of your hand, is called the dorsal aspect of the hand. The term ‘dorsal’ refers to something that is towards the back of something. In this case, it’s the back of our hand. Hence, the plantar surface refers to the sole of the foot.
What is carpal tunneling?
Carpal tunnel syndrome is when the median nerve is compressed as it passes through the carpal tunnel. The carpal tunnel is an opening in your wrist that is formed by the carpal bones on the bottom of the wrist and the transverse carpal ligament across the top of the wrist.
