User:Mr. Ibrahem/Rolando fracture

Rolando fracture is a type of broken finger involving the base of the thumb, which extends into the knuckle joint. Symptoms generally include sudden onset of pain and swelling of the thumb. Movement worsens symptoms. Complications can include long-term stiffness and osteoarthritis.

The cause is generally a force along the long axis of the thumb, such as during a fight. Diagnosis is by medical imaging; such as X-ray, CT scan, or MRI. It results in at least three bone fragments, which often form a T- or Y-shaped pattern. It differs from a Bennett fracture which only results in two bone fragments.

Treatment generally requires surgery. Options may include closed reduction with k-wire fixation or distraction with external fixation. Function generally does not return completely to normal.

Rolando fractures account for 1.4% to 4% of hand fractures and up to 20% base of thumb fractures. Males are affected about 10 times more often than females. The most common age of those affected is 20s to 30s. It was first described in 1910 by Silvio Rolando.
