S42.145S Nondisplaced fracture of glenoid cavity of scapula, left shoulder, sequela

Name of the Condition

• Nondisplaced fracture of glenoid cavity of scapula, left shoulder, sequela

Summary

A nondisplaced fracture of the glenoid cavity of the scapula, left shoulder, sequela, refers to a residual condition resulting from a prior fracture of the glenoid (the socket portion of the shoulder blade that articulates with the humerus). The term "sequela" indicates this is a complication or long-term effect of the original injury, where bone fragments remain aligned but the injury has progressed to a chronic state. This condition involves damage to the glenoid, a shallow, concave structure critical for shoulder joint stability, and may affect mobility or function due to residual healing or structural changes.

Causes

The sequela arises from a previous traumatic injury to the glenoid cavity of the left scapula. Common initial causes of the fracture include falls onto an outstretched arm, direct blows to the shoulder, or high-impact events such as motor vehicle accidents. Sports-related collisions or forceful impacts during physical activities may also result in the original fracture. The sequela develops as a result of incomplete healing, malunion, or persistent symptoms following the initial injury.

Risk Factors

• Participation in contact sports or activities with a high risk of falls, increasing the likelihood of prior injury.
• Osteoporosis or other bone-weakening conditions, which may impair healing and contribute to chronic effects.
• Advanced age, which may reduce bone density and slow recovery, leading to long-term complications.
• Previous shoulder injuries that affect bone integrity or joint function, predisposing to residual issues.

Symptoms

• Persistent pain in the shoulder or upper back, especially with movement or weight-bearing.
• Reduced range of motion or stiffness in the left shoulder.
• Swelling or tenderness in the shoulder area, even after initial healing.
• Possible clicking, grinding, or instability in the shoulder joint during activity.
• Muscle weakness or atrophy due to disuse or nerve involvement.

Diagnosis

Diagnosis of the sequela involves a thorough clinical evaluation, including a review of the patient’s medical history to confirm a prior fracture. Physical examination assesses shoulder mobility, strength, and tenderness. Imaging studies, such as X-rays or CT scans, are used to evaluate the glenoid cavity for signs of residual fracture, malunion, or degenerative changes. Additional tests, like MRI, may be ordered to assess soft tissue damage or joint integrity. The diagnosis is confirmed by correlating clinical findings with evidence of a prior injury and its long-term effects.

Treatment Options

Treatment focuses on managing symptoms and improving function. Conservative approaches include physical therapy to restore range of motion, strengthen surrounding muscles, and reduce pain. Pain management may involve NSAIDs, corticosteroid injections, or other medications. In cases of significant functional impairment, surgical intervention (e.g., arthroscopy or open reduction) may be considered to address structural abnormalities. Assistive devices, such as slings or braces, may be used temporarily to support healing or reduce strain.

Prognosis and Follow-Up

The prognosis varies depending on the severity of the residual damage and the patient’s overall health. Many patients experience improved function with conservative treatment, though some may have persistent limitations. Regular follow-up appointments monitor progress, adjust treatment plans, and address complications. Long-term outcomes may include reduced mobility or chronic pain, particularly if the sequela involves joint degeneration or nerve involvement.

Complications

• Chronic pain or discomfort in the shoulder or upper back.
• Reduced range of motion or stiffness, limiting daily activities.
• Joint instability or recurrent subluxation (partial dislocation).
• Nerve or vascular damage, leading to numbness, weakness, or circulation issues.
• Post-traumatic arthritis, resulting from joint damage or malunion.

Lifestyle & Prevention

• Engage in regular, low-impact exercises to maintain shoulder strength and flexibility.
• Use proper techniques and protective gear during sports or high-risk activities to prevent initial injuries.
• Maintain bone health through a balanced diet rich in calcium and vitamin D, and avoid smoking.
• Avoid overexertion or repetitive overhead movements that strain the shoulder joint.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, sudden loss of mobility, or signs of infection (e.g., redness, swelling, fever) in the shoulder area. Prompt evaluation is also recommended if you notice persistent numbness, weakness, or changes in skin color, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

This code (S42.145S) is used for a sequela of a nondisplaced fracture of the glenoid cavity of the scapula, left shoulder. Documentation must clearly indicate the condition is a residual effect of a prior fracture, with evidence of chronic symptoms or structural changes. Coders should verify the laterality (left shoulder) and confirm the fracture type (nondisplaced) to ensure accurate assignment. The "sequela" designation requires linkage to the original injury, and supporting clinical notes should reflect the long-term impact on function or anatomy.
