What is a volar approach?
The volar approach for dorsally displaced distal radius fractures utilizes an incision that is centered longitudinally upon the flexor carpi radialis (FCR) tendon.
What is Henry approach?
The classical Henry approach goes between brachioradialis and the radial artery, i.e., radial to the radial artery. The modified approach is ulnar to the radial artery. The flexor carpi radialis tendon is palpated, before making the skin incision to the radial side.
What is a volar radius?
Volar locking plates or distal volar radial anatomical plates are the most commonly used metallic device in the open reduction and internal stabilisation of distal radius fractures. These devices allow immediate postoperative return of motion, and are good at preventing angular displacement.
What is volar Barton fracture?
There are two types of Barton fractures. If the bump is on the back of your hand, it’s called a dorsal Barton fracture. If the bump is on the palm side, it’s called a volar or reverse Barton fracture. Reverse fractures happen more often.
What is radial inclination?
Three important measurements can be determined, using the PA view, to assess the distal radius. Radial inclination is the angle between one line drawn perpendicular to the long axis of the radius and a second line from the tip of the radial styloid to the central reference point (CRP).
What is the watershed line?
The watershed line is a useful surgical landmark for positioning a volar locking plate. Implants placed on or distal to it can impinge on flexor tendons and cause injury. However, the details of the anatomy of this line are unclear.
What is the volar surface of the wrist?
The volar aspect of the wrist includes the radius and ulna. The carpal bones are the scaphoid, leonate, triquetrum, pisiform, trapezium,trapezoid,capitate,hamate. An important structure in the volar aspect of the wrist is the Carpal tunnel.
Where is volar Barton fracture?
A Barton fracture is where you break part of your wrist and knock another part out of place. It usually happens when you fall on top of your bent wrist. The part of your wrist that breaks (your distal radius) is also part of your forearm. Your radius is the most commonly broken arm bone.
What is a volar inclination?
The volar tilt, or palmar/volar inclination, is an angle between a line drawn perpendicular to the long axis of the radius and a tangential line drawn along the radial articular surface.
What is dinner fork deformity?
A dinner fork deformity, also known as a bayonet deformity, occurs as the result of a malunited distal radial fracture, usually a Colles fracture. The distal fragment is dorsally angulated, displaced and often also impacted.
What is the difference between watershed and catchment?
“A catchment is an area of land from which water drains into a river. Every part of the earth’s land surface is part of a catchment. Neighbouring catchments are divided by watersheds, and rivers are arranged within catchments in drainage patterns.”
What is Volar in distal radius?
The volar surface of the distal radius was concave in the axial plane in all the forearms. The radial longitudinal deficiency (RLD), which is the maximum depth from line L to the volar surface of the radius at the level of the volar edge of the lunate fossa was 1.3 ± 0.6 mm.
