S42.263S Displaced fracture of lesser tuberosity of unspecified humerus, sequela

Name of the Condition

• Displaced fracture of lesser tuberosity of unspecified humerus, sequela (ICD Code: S42.263S)

Summary

This condition represents a displaced fracture of the lesser tuberosity of the humerus, occurring as a sequela (late effect) of a prior injury. The lesser tuberosity is a bony prominence near the shoulder joint that serves as an attachment point for the subscapularis tendon. Displacement may affect muscle function or joint stability, and the term "sequela" indicates residual effects following the healing phase of the original fracture.

Causes

Sequela of a displaced lesser tuberosity fracture typically result from incomplete healing, malunion, or persistent displacement after the initial injury. The original fracture may have been caused by direct trauma, such as a fall onto the shoulder, forceful arm pull, or high-impact events like motor vehicle accidents.

Risk Factors

• Advanced age and osteoporosis, which reduce bone density and healing capacity.
• Inadequate initial treatment or non-compliance with rehabilitation.
• High-impact activities or contact sports increasing re-injury risk.
• Pre-existing bone disorders or prior fractures weakening the skeletal structure.

Symptoms

• Chronic pain or discomfort in the shoulder or upper arm.
• Reduced range of motion or stiffness in the shoulder joint.
• Muscle weakness or functional impairment affecting daily activities.
• Visible deformity or persistent swelling at the fracture site.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging tests, including X-rays, to evaluate residual displacement or malunion. CT scans or MRIs may be used for detailed assessment of soft tissue or joint involvement.

Treatment Options

• Physical therapy to improve strength, flexibility, and function.
• Pain management with medications or modalities like heat/cold therapy.
• Surgical intervention (e.g., osteotomy or tendon repair) for severe malunion or functional impairment.
• Assistive devices (e.g., slings) to support healing and reduce strain.

Prognosis and Follow-Up

Prognosis depends on the extent of residual displacement, adherence to treatment, and individual healing capacity. Regular follow-up with imaging and functional assessments is recommended to monitor progress and adjust care plans as needed.

Complications

• Chronic pain or persistent functional limitations.
• Arthritis or joint degeneration due to altered mechanics.
• Nerve or vascular injury from malunion or scar tissue.
• Reduced quality of life due to activity restrictions.

Lifestyle & Prevention

• Avoid high-impact activities or heavy lifting to prevent re-injury.
• Engage in low-impact exercises (e.g., swimming, walking) to maintain mobility.
• Use proper body mechanics and protective gear during sports or work.
• Follow rehabilitation protocols to optimize healing and function.

When to Seek Professional Help

Seek care if experiencing increasing pain, new deformity, or loss of function. Immediate evaluation is recommended for signs of infection, nerve compression, or sudden worsening of symptoms.

Tips for Medical Coders

Document the sequela status clearly, including the relationship to the original fracture. Ensure clinical notes specify residual effects (e.g., pain, deformity, functional impairment) to support the sequela code. Verify that the fracture is no longer in the acute healing phase and that the sequela is directly attributable to the prior injury.
