S32.485 Nondisplaced dome fracture of left acetabulum

Name of the Condition

• Nondisplaced dome fracture of left acetabulum

Summary

This condition involves a fracture of the dome (superior weight-bearing portion) of the left acetabulum, the socket portion of the hip joint where the femur (thigh bone) articulates with the pelvis. The acetabulum is part of the pelvic bone and is critical for hip stability and movement. Nondisplaced fractures mean the bone fragments remain in their normal alignment, though joint function may still be disrupted and require management based on fracture severity.

Causes

Typically caused by high-impact trauma, such as motor vehicle accidents, falls from height, or direct blows to the hip. Less commonly, fractures may result from low-impact events in individuals with weakened bones (e.g., osteoporosis).

Risk Factors

• Advanced age, as bone density naturally decreases.
• Osteoporosis or other bone-weakening conditions.
• Participation in high-impact sports or activities.
• Previous hip or pelvic injuries.
• Certain medical conditions that affect bone strength.

Symptoms

• Severe hip or groin pain, often worsening with movement.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or tenderness around the hip.
• Limited range of motion in the hip joint.
• Possible deformity or abnormal positioning of the hip.

Diagnosis

Physical examination to assess pain, swelling, and hip function. Imaging tests, such as X-rays or CT scans, to visualize the fracture and confirm nondisplacement. Additional imaging may be used to evaluate joint integrity or associated injuries.

Treatment Options

Management depends on fracture severity and patient factors. Nondisplaced fractures may be treated with protected weight-bearing, physical therapy, and pain management. Severe cases or those with joint instability may require surgical intervention, such as internal fixation or hip preservation procedures.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures with appropriate treatment, though recovery time varies. Follow-up imaging and physical therapy are often recommended to monitor healing and restore function. Long-term outcomes depend on fracture severity, treatment adherence, and any associated injuries.

Complications

• Post-traumatic arthritis due to joint damage.
• Chronic pain or stiffness.
• Nerve or vascular injury (rare).
• Nonunion or delayed healing in severe cases.
• Reduced hip mobility or function.

Lifestyle & Prevention

• Use protective gear during high-impact activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).
• Follow post-injury activity restrictions to support healing.

When to Seek Professional Help

Seek immediate care for severe hip pain, inability to bear weight, or visible deformity after trauma. Follow up with a healthcare provider if pain persists, worsens, or if mobility does not improve with treatment.

Tips for Medical Coders

Document the side (left), fracture location (dome of acetabulum), and displacement status (nondisplaced) to support accurate coding. Include details on trauma mechanism, imaging findings, and treatment approaches, as these may impact code assignment and reimbursement. Ensure documentation aligns with clinical guidelines for acetabular fractures.
