Things worth knowing about "S62.3"

S62.3 is the ICD-10 code for a fracture of the metacarpal bone. This injury commonly results from a fall or direct impact to the hand.

What Does the ICD-10 Code S62.3 Mean?

The ICD-10 code S62.3 refers to a fracture of the metacarpal bone, meaning a break in one or more of the five long bones that form the palm of the hand. The metacarpus connects the wrist bones (carpals) to the finger joints (phalanges). Metacarpal fractures are among the most common hand injuries seen in clinical practice and affect people of all ages.

Causes

Metacarpal fractures typically result from direct or indirect trauma to the hand:

Fall onto an outstretched hand
Punching a hard surface with a closed fist (often called a "boxer's fracture," typically involving the 5th metacarpal)
Road traffic accidents or workplace injuries
Sports injuries, for example in handball, volleyball, or martial arts
Crush injuries or direct compression

Symptoms

Common signs and symptoms of a metacarpal fracture include:

Pain over the back of the hand, especially with pressure or movement
Swelling and bruising (hematoma) over the affected bone
Reduced range of motion of the hand and fingers
Visible deformity or malalignment of the bone
Crepitation (a grating sensation) when the hand is moved (to be assessed by a physician only)
Rotational malalignment of a finger, visible when making a fist

Diagnosis

Diagnosis is confirmed through clinical examination and imaging:

Physical examination: Assessment of swelling, point tenderness, range of motion, and rotational alignment of the fingers
X-ray of the hand in at least two planes (standard): identifies the fracture and evaluates displacement of bone fragments
CT scan (computed tomography): Used for complex or intra-articular fractures to provide detailed imaging

Treatment

Conservative Management

Non-displaced or minimally displaced fractures are generally treated conservatively:

Immobilization with a plaster splint or functional brace for 4 to 6 weeks
Ice application and elevation of the hand in the acute phase to reduce swelling
Pain management using non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or diclofenac
Physiotherapy following bone consolidation

Surgical Treatment

Significantly displaced, unstable, or intra-articular fractures may require surgery:

Kirschner wire fixation: Thin metal wires are inserted to stabilize the fracture
Plate and screw osteosynthesis: A metal plate is fixed to the bone with screws
Screw fixation alone: Used for specific fracture patterns

Healing and Prognosis

Most metacarpal fractures heal without complications within 6 to 8 weeks when treated appropriately. Full recovery of hand function is generally achievable. However, rotational malalignment or untreated displacement can lead to long-term functional impairment. Regular follow-up and early physiotherapy significantly improve outcomes.
