Code Description

ICD-10 S42.333 is a billable code used to indicate a diagnosis of displaced oblique fracture of shaft of humerus, unspecified arm.

Key Diagnostic Point:

A displaced oblique fracture of the shaft of the humerus is characterized by a break in the bone that occurs at an angle, resulting in the bone fragments being misaligned. This type of fracture typically occurs due to trauma, such as falls or direct blows to the arm. Patients may present with severe pain, swelling, and limited range of motion in the affected arm. Diagnosis is confirmed through imaging studies, such as X-rays, which reveal the fracture's location and displacement. Treatment often involves orthopedic intervention, which may include closed reduction and immobilization with a splint or cast. In more severe cases, surgical repair may be necessary to realign the bone fragments and stabilize the fracture using plates, screws, or intramedullary nails. Rehabilitation is crucial for restoring function and strength to the arm post-injury. Complications can include nonunion, malunion, or injury to surrounding nerves and blood vessels.
