What do you do for a proximal phalanx fracture?
Proximal phalanx fracture – undisplaced Your fracture can be treated with splinting, taping or casting (or a combination of all three of these). Generally a cast is only used for treating phalangeal fractures for children or individuals who will not be able to keep their fingers safely immobilised with a splint.
How long does it take for a proximal phalanx fracture to heal?
Many stable phalanx fractures can be treated nonoperatively through close monitoring until clinical healing is noted. Proximal phalanx fractures will often be clinically healed 4 weeks status post injury, at which time it is unlikely that the fracture will displace.
What joint is at the base of the thumb proximal phalanx?
The first MPJ is an ellipsoid synovial joint composed of the first metatarsal and the proximal phalanx of the hallux. The rounded, convex head of the distal first metatarsal articulates with the shallow, concave base of the proximal phalanx. In addition, two small plantar sesamoid bones contribute to the first MPJ.
Can you fracture base of thumb?
Bennett and Rolando fractures are breaks at the base of the thumb. They involve the joint between the thumb metacarpal and a specific wrist bone. Fractures that involve the joints are always more difficult to treat and are at increased risk of an unfavorable outcome.
Where is the base of the proximal phalanx?
toe
Proximal phalanges (foot) are the largest bones in the toe. They form the base of the toe and are a separate bone from the middle phalanges (the center bones in the toes) and the distal phalanges (the bones at the tip of the toes). They are connected to the metatarsals, or long bones in the feet, by cartilage.
What is a proximal phalanx fracture?
Proximal phalanx fractures often present with apex volar angulation. Interosseus muscles and lumbricals insert onto the base of the proximal phalanx and flex the proximal fragment. The flexor and extensor tendons impart a longitudinal compression force, which can shorten the phalanx and extend the distal fragment [1].
How long does a hairline fracture in thumb take to heal?
A complete recovery will typically take between 6 to 8 weeks, after which full mobility should be restored. In some cases, a doctor may recommend protective footwear, a splint, or the use of crutches to minimise strain placed on the fractured bone during movement.
What causes proximal phalanx fracture?
Forceful hyperextension of the finger produces shaft or base fractures of a proximal phalanx. This is similar to the kind of force that leads to proximal interphalangeal joint or metacarpophalangeal joint dislocations.
What is proximal phalanx fracture?
How is a phalanx fracture of the hand treated?
Phalanx fractures are common hand injuries that involve the proximal, middle or distal phalanx. Diagnosis can be confirmed with orthogonal radiographs of the involve digit. Treatment involves immobilization or surgical fixation depending on location, severity and alignment of injury.
Are there any fractures in the proximal phalanx?
– Impacted fractures in the proximal portion of the proximal phalanx of the finger. Treatment principles for proximal and middle phalangeal fractures. Articular fractures of the digits: a prospective study. A prospective study of 245 open digital fractures of the hand.
When to do a radiograph of the proximal phalanx?
Fig. 16.1 An intra-articular avulsion fracture of the base of the proximal phalanx is a consequent of ligament stability superior to bone strength. Plain radiographs (posteroanterior [PA] and lateral views) of the injured finger should always be performed when a fracture is suspected.
What kind of fractures occur at the base of the thumb?
Description. This is particularly true when the fracture occurs at the base of the thumb near the wrist. There are specific types of thumb fractures, depending on the type of break. Bennett and Rolando fractures are breaks at the base of the thumb. They involve the joint between the thumb metacarpal and a specific wrist bone.
