S42.112S Displaced fracture of body of scapula, left shoulder, sequela

Name of the Condition

• Displaced fracture of body of scapula, left shoulder, sequela

Summary

A displaced fracture of the body of the scapula, left shoulder, sequela refers to a healed or healing fracture of the main, flat portion of the shoulder blade bone, with the fractured fragments remaining out of their normal alignment. This condition affects the left shoulder and represents the residual effects of a previous injury, which may include chronic pain, functional limitations, or structural changes. The scapula connects the upper arm to the collarbone and trunk, and persistent displacement can impact shoulder mechanics and overall upper extremity function.

Causes

This condition arises as a sequela (late effect) of a prior displaced fracture of the scapula body. The original injury was typically caused by significant trauma, such as motor vehicle accidents, falls from height, or direct forceful blows to the shoulder. High-energy impacts, sports-related collisions, or crush injuries may have initially displaced the bone fragments, leading to the current residual state.

Risk Factors

• Previous trauma to the left shoulder or upper back.
• Inadequate initial treatment or healing of the original fracture.
• Underlying bone conditions (e.g., osteoporosis) that may have contributed to the initial fracture severity.
• Advanced age, which can affect bone healing and recovery.

Symptoms

• Chronic pain in the shoulder or upper back, often persistent or recurrent.
• Reduced range of motion in the shoulder joint, limiting daily activities.
• Muscle weakness or fatigue in the affected arm.
• Possible visible or palpable deformity of the shoulder blade.
• Occasional discomfort during overhead movements or weight-bearing activities.

Diagnosis

Diagnosis involves a thorough clinical evaluation, including a review of the patient’s medical history to confirm a prior scapula fracture. Physical examination assesses shoulder function, range of motion, and any residual deformity. Imaging studies, such as X-rays or CT scans, may be used to visualize the healed fracture and assess alignment. Functional assessments help determine the impact on daily activities.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to restore mobility and strength, pain management strategies, and adaptive equipment for daily tasks. In some cases, surgical intervention (e.g., osteotomy or stabilization) may be considered to correct severe displacement, though this is less common in sequela cases. Rehabilitation emphasizes gradual, targeted exercises to optimize shoulder mechanics.

Prognosis and Follow-Up

Prognosis depends on the severity of the residual displacement and the patient’s response to treatment. Many individuals experience improved function with therapy, though some may have persistent limitations. Regular follow-up appointments monitor progress, address complications, and adjust treatment plans as needed. Long-term management may involve periodic imaging to assess healing and functional outcomes.

Complications

• Chronic pain or discomfort.
• Persistent limited range of motion or stiffness.
• Muscle atrophy or weakness in the shoulder girdle.
• Post-traumatic arthritis in the shoulder joint.
• Nerve or vascular irritation from malaligned bone fragments.

Lifestyle & Prevention

• Engage in regular, low-impact exercises to maintain shoulder flexibility and strength.
• Avoid activities that strain the affected shoulder, such as heavy lifting or repetitive overhead motions.
• Use proper body mechanics during daily tasks to reduce stress on the shoulder.
• Wear protective gear during high-risk activities (e.g., sports) to prevent future injuries.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or a sudden decrease in shoulder function. Prompt evaluation is also recommended if you notice increased difficulty with daily activities or signs of infection (e.g., redness, warmth) at the injury site.

Tips for Medical Coders

This code (S42.112S) is used for a displaced fracture of the scapula body, left shoulder, sequela. Documentation should clearly indicate the condition is a late effect of a prior fracture, with details on the residual displacement and its impact on function. Ensure the sequela is linked to the original injury and that the left shoulder and scapula body are specified. Avoid using this code for acute fractures or other shoulder conditions.
