In a UK study involving nearly 6000 fractures seen in hospital, 3.6% were broken toes. [10] Fractures of big toes make up about a fifth [3] or third [8] of all toe fractures, and 5.5% of all foot and ankle fractures in major US trauma hospitals. [10] Toe fractures are the most common foot fractures. [8] About 20% of broken toes involve open ...
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 ...
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 neck of a metacarpal is a common location for a boxer's fracture, but all parts of the metacarpal bone (including head, body and base) are susceptible to fracture. During their lifetime, 2.5% of individuals will experience at least one metacarpal fracture. Bennett's fracture (base of the thumb) is the most common. [4]
821 Fracture of other and unspecified parts of femur; 822 Fracture of patella; 823 Fracture of tibia and fibula; 824 Fracture of ankle; 825 Fracture of one or more tarsal and metatarsal bones; 826 Fracture of one or more phalanges of foot; 827 Other, multiple, and ill-defined fractures of lower limb; 828 Multiple fractures involving both lower ...
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.
The palmar plate moves in three phases during joint flexion. First, it slides back toward the hand. Next, it is lifted away from the proximal phalanx by the A3 pulley. Last, a lip on the middle phalanx rolls into a recess on the plate. If the A3 pulley is not intact, the normal three phases of motion do not occur and instead the plate crumples. [7]
Proximal fractures of 5th metatarsal. The tuberosity avulsion fracture (also known as pseudo-Jones fracture or dancer's fracture [2] is a common fracture of the fifth metatarsal (the bone on the outside edge of the foot extending to the little toe). [3] This fracture is likely caused by the lateral band of the plantar aponeurosis (tendon). [4]
