S42.261S Displaced fracture of lesser tuberosity of right humerus, sequela

Name of the Condition

• Displaced fracture of lesser tuberosity of right humerus, sequela (ICD Code: S42.261S)

Summary

This condition represents a displaced fracture of the lesser tuberosity of the right humerus that has entered a sequela phase, indicating residual effects following the acute injury. The lesser tuberosity is a bony prominence on the front of the humerus near the shoulder joint, serving as an attachment point for the subscapularis tendon. Sequela implies the fracture has healed but may result in persistent functional or structural changes, such as limited mobility or chronic pain.

Causes

Sequela fractures of the lesser tuberosity typically result from prior trauma, such as a fall onto the shoulder, forceful arm pull, or high-impact injury. The sequela phase arises after the initial fracture has healed, with residual effects stemming from the original injury mechanism and healing process.

Risk Factors

• Advanced age and osteoporosis, which may contribute to fracture severity and delayed healing.
• Inadequate rehabilitation or immobilization during the acute phase, increasing the risk of long-term complications.
• High-impact trauma during the initial injury, which can lead to more significant displacement or associated soft tissue damage.

Symptoms

• Chronic shoulder or upper arm pain, particularly with movement.
• Reduced range of motion or stiffness in the shoulder joint.
• Possible muscle weakness or atrophy due to prolonged disuse.
• Occasional swelling or discomfort at the fracture site during activity.

Diagnosis

Clinical evaluation to assess residual pain, functional limitations, and range of motion. Imaging, such as X-rays or MRIs, may be used to evaluate healed fracture alignment and identify any persistent displacement or associated joint changes. History of the original injury and prior treatment is critical for diagnosis.

Treatment Options

Management focuses on symptom relief and functional restoration. Options may include physical therapy to improve strength and mobility, pain management, and activity modification. Surgical intervention is rarely needed in the sequela phase unless significant functional impairment persists.

Prognosis and Follow-Up

Prognosis depends on the extent of initial injury and adherence to rehabilitation. Most patients experience improved function with therapy, though some may have permanent limitations. Regular follow-up ensures monitoring for complications and adjustment of treatment plans as needed.

Complications

• Chronic shoulder pain or stiffness.
• Reduced strength or mobility in the affected arm.
• Potential for secondary arthritis if joint alignment was compromised.
• Nerve irritation or impingement due to residual bone or soft tissue changes.

Lifestyle & Prevention

• Engage in regular shoulder-strengthening exercises to maintain mobility.
• Avoid activities that place excessive stress on the shoulder joint.
• Use proper techniques during physical tasks to minimize injury risk.
• Follow post-injury rehabilitation guidelines to optimize recovery.

When to Seek Professional Help

Seek care if chronic pain worsens, mobility significantly decreases, or new symptoms (e.g., numbness, swelling) develop. Prompt evaluation is important to address complications or adjust treatment.

Tips for Medical Coders

Document the sequela status clearly, including the original injury date and evidence of residual effects. Ensure the code S42.261S is used only when the fracture has entered the sequela phase, with supporting clinical notes confirming healed fracture and ongoing symptoms or functional changes.
