Name of the Condition

  • Displaced fracture of body of scapula, left shoulder, subsequent encounter for fracture with nonunion

Summary

A displaced fracture of the body of the scapula involves a break in the main, flat portion of the shoulder blade bone, with the fractured fragments shifted out of their normal alignment. This condition affects the left shoulder and is classified as a subsequent encounter for a fracture with nonunion, indicating that the bone has failed to heal properly after an initial injury. Nonunion may result in persistent pain, functional impairment, and increased risk of complications if not addressed.

Causes

Traumatic injury is the primary cause, often resulting from high-impact events such as motor vehicle accidents, falls from height, or direct forceful blows to the shoulder. Sports-related collisions or crush injuries may also lead to this type of fracture. Nonunion can occur due to inadequate immobilization, poor blood supply to the fracture site, infection, or excessive movement during the healing process.

Risk Factors

  • Participation in contact sports or activities with a high risk of falls.
  • Osteoporosis or other bone-weakening conditions.
  • Advanced age, which may increase susceptibility to fractures from minor trauma.
  • Previous shoulder or upper arm injuries that affect bone integrity.
  • Smoking or poor nutrition, which can impair bone healing.

Symptoms

  • Persistent pain in the shoulder or upper back, worsening with movement.
  • Swelling, bruising, or tenderness over the shoulder blade.
  • Limited range of motion in the shoulder joint.
  • Difficulty lifting or rotating the arm.
  • Possible visible deformity or instability in severe cases.
  • Sensation of the bone shifting or grinding during movement.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture and evaluate for nonunion. Additional tests, like bone scans or MRI, may be performed to assess blood flow and tissue viability. The healthcare provider will review the patient’s medical history, including prior treatments and healing progress, to determine the extent of the nonunion.

Treatment Options

Treatment focuses on promoting bone healing and restoring function. Options may include surgical intervention, such as bone grafting or internal fixation, to stabilize the fracture. Non-surgical approaches, like prolonged immobilization or electrical stimulation, may be considered for less severe cases. Physical therapy is often recommended to improve strength and mobility once healing is underway. Pain management and addressing underlying risk factors, such as osteoporosis, are also key components of care.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. With proper management, many patients achieve significant improvement in pain and function, though full recovery may take several months. Regular follow-up appointments, including imaging studies, are necessary to monitor healing progress. Long-term outcomes may vary, and some patients may experience residual stiffness or weakness.

Complications

  • Chronic pain or discomfort.
  • Persistent limited range of motion.
  • Increased risk of future fractures due to weakened bone.
  • Nerve or blood vessel damage near the fracture site.
  • Infection, particularly if surgical intervention is required.
  • Muscle atrophy from prolonged immobilization.

Lifestyle & Prevention

  • Avoid high-impact activities until cleared by a healthcare provider.
  • Engage in low-impact exercises, such as swimming or walking, to maintain mobility.
  • Ensure adequate intake of calcium and vitamin D to support bone health.
  • Quit smoking, as it impairs bone healing.
  • Use protective gear during sports or activities with a risk of falls.

When to Seek Professional Help

Seek immediate medical attention if you experience:

  • Sudden, severe pain or swelling in the shoulder.
  • Inability to move the arm or shoulder.
  • Signs of infection, such as fever, redness, or pus.
  • Numbness or tingling in the arm or hand.
  • A visible deformity or instability in the shoulder.

Tips for Medical Coders

When coding for this condition, ensure the documentation specifies a displaced fracture of the scapula body, left shoulder, and confirms a subsequent encounter for fracture with nonunion. Verify that the encounter is not an initial or acute phase, as this impacts code selection. Document any contributing factors, such as trauma history or prior treatments, to support the diagnosis and code accuracy.
