What defines a proximal phalanx fracture?

A proximal phalanx fracture involves a break in the proximal phalanx, which is the bone in the finger or thumb closest to the metacarpal (hand) bone. This type of fracture can occur in any of the digits but is most common in the middle and ring fingers.

What are the common causes of these fractures?

-Proximal phalanx fractures typically result from direct trauma to the hand.
-Sports injuries and falls are frequently culprits.
-These can also be stress or fatigue fractures, which occur from repetitive actions like certain types of athletic training.

What are the notable symptoms?

-Marked pain and tenderness at the site of fracture
-Rapid onset of swelling
-Deformity or shortening of the finger
-Difficulty moving the affected digit
-Possible open wound if the fracture is compound

What diagnostic methodologies typically come into play?

-X-ray imaging is the primary tool to confirm a fracture and determine its type and extent.
-Rarely, a CT scan may be used to understand better the fracture pattern and involvement of the articular surface.
-Ultrasound can be used if an associated tendon lesion is suspected.

What are the initial treatment strategies for proximal phalanx fractures?

-Immobilization of the finger and hand using a splint or cast to allow for healing.
-Analgesia for pain management, often non-steroidal anti-inflammatory drugs.
-Reduction can be required if the fracture is displaced.
-In cases of open fracture, immediate antibiotic prophylaxy to prevent infection.
-Referral to a hand specialist for further evaluation and treatment as these fractures can have complications if not managed correctly, such as nonunion, malunion or osteoarthrosis..
