[1] [13] In such a fracture, the hard blow to the tip of the distal phalanx typically results in a transverse or oblique fracture in the proximal phalanx (base of toe), but can occur in any phalanx. [1] [13] An open wound toe fracture may result from an injury from a lawn mower. [6]
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
Open fractures are usually operated on. [1] A Busch fracture is a specific type of finger fracture where the base of a distal phalanx is affected. [5] Without adequate treatment, it can become a mallet finger.
The Rolando fracture is a type of broken finger involving the base of the thumb. [1] It is an intra-articular fracture. [2] It was first described in 1910 by Silvio Rolando. [3] It is typically T- or Y-shaped. [4]
Bennett fracture is a type of partial broken finger involving the base of the thumb, and extends into the carpometacarpal (CMC) joint. [ 1 ] Treatment typically requires surgery.
A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx. Each extends obliquely in a palmar direction from its proximal attachment to its distal attachment. [2]
The palmar ligament is thinner and more flexible in its central-proximal part. On both sides it is reinforced by the so-called check rein ligaments. The accessory collateral ligaments (ACL) originate at the proximal phalanx and are inserted distally at the base of the middle phalanx below the collateral ligaments. [1]
A Stener lesion is a type of traumatic injury to the thumb.It occurs when the aponeurosis of the adductor pollicis muscle becomes interposed between the ruptured ulnar collateral ligament (UCL) of the thumb and its site of insertion at the base of the proximal phalanx.
