Which complication of fractures is a result of excessive callus formation at the fracture site?

Patients with external fixation require close monitoring of the pin sites for signs of infection, as they are at risk of developing pin site infections.

a. Providing passive range of motion exercises: Passive range of motion exercises may be appropriate in some cases, but they are not specific to external fixation management.
b. Changing the dressing daily: Dressing changes for external fixation are typically done as instructed by the healthcare provider, which may not necessarily be daily.
c. Loosening the fixation screws every 4 hours: Fixation screws should not be loosened without proper medical guidance, as this can compromise the stability of the external fixation device.

Closed reduction is a non-surgical procedure used to manually realign the fractured bone to its normal position without making an incision. It is often followed by cast immobilization or other forms of stabilization.

a. To surgically realign the fractured bone: Surgical realignment is typically performed through open reduction and internal fixation (ORIF), not closed reduction.
b. To stabilize the fracture with internal fixation: Internal fixation involves the use of screws, plates, or rods to stabilize fractures, and it is not part of the closed reduction procedure.
c. To immobilize the fractured bone with a cast: Immobilization with a cast may follow closed reduction, but it is not the primary goal of the reduction procedure itself.
