Presence of Left Artificial Hip Joint (ICD Code: Z96.642)

Name of the Condition

• Common Name: Left Hip Prosthesis
• Medical Term: Presence of Left Artificial Hip Joint

Summary

The presence of a left artificial hip joint refers to a condition where an individual has undergone hip replacement surgery, and a prosthetic device has been implanted to replace the natural hip joint on the left side. This is typically done to relieve pain and restore mobility.

Causes

The need for a hip prosthesis usually arises due to severe joint damage caused by conditions such as osteoarthritis, rheumatoid arthritis, hip fractures, or avascular necrosis.

Risk Factors

• Advanced age, typically over 60
• History of joint disease or injury
• High-impact or injury-prone occupations or sports
• Genetics, potentially influencing bone density or joint health

Symptoms

Before surgery, patients may experience joint pain, stiffness, and limited mobility. Post-surgery, symptoms include initial surgical pain, but ideally lead to significant pain reduction and improved mobility.

Diagnosis

Diagnosis of the need for a hip prosthesis involves:

• Physical examinations
• Imaging tests like X-rays or MRI to assess joint damage The presence of the artificial joint post-surgery is confirmed via medical history and follow-up imaging if needed.

Treatment Options

Following hip replacement surgery, treatments include:

• Pain management: medications for postoperative pain relief
• Physical therapy: to restore function and mobility
• Regular follow-ups: to monitor the condition of the prosthesis

Prognosis and Follow-Up

Most individuals experience substantial pain relief and improved quality of life. Regular follow-ups are critical to ensure the prosthesis is functioning well and to check for wear and potential complications.

Complications

Possible complications include:

• Infection around the prosthesis
• Prosthesis dislocation or wearing down
• Bone growth issues or loosening of the implant

Lifestyle & Prevention

Post-surgery lifestyle changes to optimize long-term outcomes include:

• Maintaining a healthy weight to reduce joint stress
• Regular low-impact exercise to strengthen muscles and improve joint function
• Avoiding high-impact activities that could damage the prosthesis

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, redness, or warmth around the hip area, as these may indicate complications requiring prompt intervention.
