S73.014D Posterior dislocation of right hip, subsequent encounter

Name of the Condition

• Common Name: Posterior Dislocation of Right Hip
• Technical Term: Posterior Dislocation of Right Hip

Summary

This condition involves the complete displacement of the right hip joint, where the femoral head moves posteriorly out of its normal position within the acetabulum. It is a traumatic injury that disrupts joint stability and function, often requiring prompt clinical evaluation. The term "subsequent encounter" indicates this is a follow-up visit for the condition.

Causes

Traumatic events such as falls, motor vehicle accidents, or high-impact sports injuries. Sudden forceful movements, such as those occurring during twisting or direct blows to the hip, can force the femur out of alignment.

Risk Factors

• Participation in contact sports or activities with high fall risk.
• Osteoporosis or weakened bone structure.
• Previous hip injuries or joint instability.
• Age-related degenerative changes in the joint.

Symptoms

• Severe hip pain and inability to bear weight on the right leg.
• Visible deformity or abnormal positioning of the right hip.
• Limited range of motion or inability to move the right leg.
• Numbness or tingling in the right leg (possible nerve involvement).

Diagnosis

Physical examination to assess joint stability, pain, and deformity. Imaging tests (X-rays, CT, or MRI) to confirm posterior displacement and rule out fractures. Evaluation of neurovascular status to check for associated injuries.

Treatment Options

• Closed reduction to realign the joint, often under anesthesia.
• Immobilization with a splint or brace to allow healing.
• Physical therapy to restore strength and mobility.
• Surgical intervention if closed reduction is unsuccessful or complications arise.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timeliness of treatment. Most patients recover function with appropriate care, but some may experience long-term stiffness or arthritis. Follow-up visits monitor healing and rehabilitation progress.

Complications

• Avascular necrosis of the femoral head due to disrupted blood supply.
• Nerve or blood vessel damage.
• Chronic hip instability or recurrent dislocation.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Avoid high-risk activities or use protective gear during sports.
• Maintain bone health through diet and exercise to reduce fracture risk.
• Use assistive devices (e.g., canes) if balance or mobility is impaired.
• Follow rehabilitation guidelines to restore strength and prevent re-injury.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, visible deformity, or numbness/tingling after a fall or injury. Follow up with a healthcare provider for persistent pain or limited mobility during recovery.

Tips for Medical Coders

Document the laterality (right hip) and encounter type (subsequent) clearly. Ensure clinical notes specify the dislocation direction (posterior) and any associated injuries. Verify that the encounter is for follow-up care, not initial treatment, to support accurate coding.
