S42.124 Nondisplaced fracture of acromial process, right shoulder

Name of the Condition

• Nondisplaced fracture of acromial process, right shoulder

Summary

A nondisplaced fracture of the acromial process of the right shoulder involves a break in the bony projection (acromion) of the scapula where the bone fragments remain aligned. The acromial process forms part of the shoulder's roof and connects to the clavicle, contributing to joint stability. This injury typically results from trauma and may affect shoulder function due to pain or associated soft tissue damage, though alignment is preserved.

Causes

Traumatic injury is the primary cause, often from a direct blow to the shoulder, a fall onto the shoulder, or a forceful impact during activities like sports or accidents. High-energy events, such as motor vehicle collisions, can also lead to this type of fracture.

Risk Factors

• Participation in contact sports or activities with a risk of shoulder impact.
• Osteoporosis or conditions that weaken bone density.
• Advanced age, which may increase susceptibility to fractures from minor trauma.
• Previous shoulder injuries that compromise bone integrity.

Symptoms

• Pain localized to the top of the shoulder, especially with movement.
• Swelling, bruising, or tenderness over the acromial area.
• Limited range of motion in the shoulder joint.
• Difficulty lifting or rotating the arm.
• In severe cases, a visible deformity or instability may be present.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and tenderness over the acromial process. Imaging studies, typically X-rays, are used to confirm the fracture and verify that the bone fragments are aligned (nondisplaced). Additional imaging, such as CT or MRI, may be ordered if soft tissue damage or associated injuries are suspected.

Treatment Options

Treatment focuses on pain management and restoring function. Conservative approaches include rest, ice, and over-the-counter pain relievers. Immobilization with a sling may be recommended for comfort. Physical therapy is often introduced to regain range of motion and strength once initial pain subsides. Most nondisplaced fractures heal without surgery, but follow-up imaging ensures proper healing.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, with most patients recovering full function over several weeks to months. Follow-up appointments monitor healing through clinical assessment and repeat imaging if needed. Adherence to activity restrictions and rehabilitation guidelines is key to avoiding complications.

Complications

While rare, potential complications include nonunion (failure to heal), malunion (healing in a misaligned position), or persistent pain. Nerve or blood vessel injury near the fracture site is also possible but uncommon. Early intervention and proper follow-up reduce these risks.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use proper protective gear during sports or work that involves shoulder risk.
• Maintain bone health through adequate calcium and vitamin D intake, especially for those with osteoporosis.
• Practice fall prevention strategies, such as home modifications, to reduce injury risk.

When to Seek Professional Help

Seek immediate care for severe pain, visible deformity, or inability to move the shoulder. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment, or if numbness, tingling, or weakness in the arm develops.

Tips for Medical Coders

Document the side (right shoulder) and fracture type (nondisplaced) clearly in the medical record. Ensure the diagnosis is supported by clinical findings and imaging results. For coding accuracy, confirm the fracture is isolated to the acromial process and not associated with other shoulder injuries unless documented.
