S42.026 Nondisplaced fracture of shaft of unspecified clavicle

Name of the Condition

• Nondisplaced fracture of shaft of unspecified clavicle (ICD-10 Code: S42.026)

Summary

A nondisplaced fracture of the shaft of the unspecified clavicle is a break in the middle portion of the collarbone where the bone fragments remain aligned. This condition involves the central third of the clavicle and typically results from trauma, causing pain and functional impairment of the shoulder without significant displacement of the bone fragments.

Causes

This fracture commonly occurs due to direct trauma to the shoulder or a fall onto an outstretched hand. Typical scenarios include sports injuries, motor vehicle accidents, or falls from a height, where force is applied to the clavicle, leading to a break while maintaining alignment of the bone fragments.

Risk Factors

Factors that increase the likelihood of this fracture include participation in contact sports, osteoporosis or weakened bone density, and older age due to increased fall risk. Activities involving high-impact forces to the upper body also raise susceptibility.

Symptoms

Symptoms often include sudden pain in the shoulder or collarbone area, swelling, bruising, tenderness, difficulty moving the shoulder, and a visible bump or deformity at the fracture site. Pain may worsen with arm movement or pressure on the area, though displacement is minimal or absent.

Diagnosis

Diagnosis involves a physical examination to assess pain and deformity, followed by X-ray imaging to confirm the fracture and its location. Clinical evaluation focuses on determining the absence of significant displacement, which distinguishes this from other clavicle fractures.

Treatment Options

Treatment typically includes pain management with analgesics, immobilization using a sling or brace to support the arm, and activity modification to allow healing. Physical therapy may be recommended to restore range of motion and strength once initial healing occurs.

Prognosis and Follow-Up

Prognosis is generally favorable, with most fractures healing within 6–8 weeks. Follow-up care involves monitoring for healing progress, assessing functional recovery, and adjusting treatment as needed. Regular check-ups ensure proper alignment and address any complications.

Complications

Potential complications include nonunion (failure to heal), malunion (healing in an abnormal position), or persistent pain. Rarely, nerve or vascular injury may occur, though displacement is minimal in this type of fracture.

Lifestyle & Prevention

Preventive measures include using protective gear during contact sports, maintaining bone health through adequate calcium and vitamin D intake, and reducing fall risks in older adults. Strengthening shoulder and upper body muscles may also help absorb impact.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, or there is difficulty moving the arm. Immediate care is needed if numbness, tingling, or changes in skin color occur, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

Document the absence of displacement and specify the clavicle shaft involvement. Ensure clinical notes confirm the fracture is nondisplaced and unrelated to other clavicle regions. Code S42.026 is appropriate when the clavicle shaft is fractured without displacement and the side is unspecified.
