How do you reduce a metacarpal neck fracture?
Most closed simple metacarpal neck fractures can be managed conservatively by flexing the digit at the metacarpophalangeal and proximal interphalangeal joints and applying a dorsally directed force along the plane of the first phalanx. Stable fractures can then be splinted externally.
How do you use a metacarpal splint?
Apply stockinette, covering the area from the mid-forearm to the metacarpals. Insert padding between the 4th and 5th fingers to prevent skin maceration and then wrap padding around both the fingers.
How do you fix a dislocated metacarpal?
Metacarpal fracture or dislocation can be treated non-surgically by aligning the fractured bones and checking the movement of fingers, under local anesthesia. The fractured hand is wrapped with forearm-based splints or a cast to immobilize the bone to promote natural healing.
Where is the first metacarpal located?
the thumb
The first metacarpal bone is associated with the thumb. The joints between the carpals and the metacarpals are known as carpometacarpal joints. The joints between the metacarpals and the proximal phalanges are known a metacarpophalangeal joints.
In what position should the hand be placed when splinting the wrist hand and fingers?
The hand is positioned as if holding a can of soda; this is with the thumb abducted with the first interphalangeal joint in extension. The plaster should extend past the interphalangeal joint in order to fully immobilize the thumb. The wrist is splinted in a neutral position.
How do I immobilize my MCP?
Generally, the wrist should be placed in 20-30° of extension; the metacarpophalangeal (MCP) joints should be immobilized in 70-90° of flexion, with the dorsal aspect of the splint extending to the IP joints; and the volar aspect should end at the distal palmar crease.
Can you dislocate metacarpals?
The trapezoid metacarpal dislocation is a rare event. In the literature, it is found in case reports. This injury is caused by direct or indirect high energy trauma. In most cases, the dislocation is dorsal and is difficult to reproduce because the joint is not very mobile.
Can you pop a dislocated finger back in place?
Most simple finger dislocations can be put back into place easily. Full function in the injured finger will usually return.
