S42.025 Nondisplaced fracture of shaft of left clavicle

Name of the Condition

• Nondisplaced fracture of shaft of left clavicle (ICD-10 Code: S42.025)

Summary

A nondisplaced fracture of the shaft of the left clavicle is a break in the middle portion of the left 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 usually occurs due to direct trauma to the shoulder or a fall onto an outstretched hand. Common scenarios include motor vehicle accidents, sports injuries, or falls from a height, where force applied to the clavicle causes it to 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 not present.

Diagnosis

Diagnosis involves a physical examination to assess pain and deformity, followed by X-ray imaging to confirm the fracture and its location. In some cases, additional imaging like CT scans may be used to evaluate bone alignment and rule out other injuries.

Treatment Options

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

Prognosis and Follow-Up

Most nondisplaced clavicle fractures heal well with conservative treatment, often within 6 to 12 weeks. Follow-up appointments monitor healing progress, and imaging may be repeated to ensure proper alignment. Full recovery of function is common, though some residual stiffness or weakness may persist.

Complications

Complications are rare but can include nonunion (failure to heal), malunion (healing in an abnormal position), or nerve injury. Infection is uncommon but possible if the fracture is open. Persistent pain or functional limitations may require further evaluation.

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 and reduce fracture risk.

When to Seek Professional Help

Seek medical attention if there is severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., redness, warmth, fever). Immediate care is also needed if the injury results from a high-impact event like a motor vehicle accident.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the left clavicle shaft. Include details on trauma mechanism, imaging results, and treatment provided. Ensure alignment with clinical findings to support the nondisplaced classification.
