M76.1 Psoas tendinitis

Name of the Condition

Psoas Tendinitis

Summary

Psoas tendinitis is an inflammatory condition affecting the psoas tendon, which connects the psoas muscle to the femur. This condition typically causes pain and discomfort in the hip or groin region, often resulting from overuse or mechanical stress. It may limit mobility and functional activities involving hip flexion.

Causes

Psoas tendinitis commonly arises from repetitive strain or overuse of the psoas tendon, such as during activities involving hip flexion (e.g., running, cycling, or prolonged sitting). Direct trauma to the tendon or sudden increases in physical activity can also trigger inflammation. Poor biomechanics or muscle imbalances may contribute to tendon irritation over time.

Risk Factors

• Participation in activities requiring repetitive hip flexion, such as sports or manual labor.
• Age-related tendon degeneration, which reduces tissue resilience.
• Previous hip or groin injuries affecting the psoas tendon.
• Sedentary lifestyles followed by sudden increases in activity intensity.

Symptoms

• Localized pain in the hip, groin, or lower abdomen, often worsening with movement.
• Tenderness or swelling around the psoas tendon attachment site.
• Stiffness or reduced range of motion in the hip, particularly during flexion.
• Pain that intensifies during weight-bearing activities or prolonged sitting.

Diagnosis

Diagnosis is based on a physical examination and patient history, focusing on the location and nature of pain. Imaging tests like MRI or ultrasound may be used to assess tendon integrity and rule out other conditions. Clinical evaluation typically includes assessing hip flexion and palpation of the psoas tendon.

Treatment Options

• Rest and activity modification to reduce strain on the psoas tendon.
• Physical therapy to strengthen surrounding muscles and improve biomechanics.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) to manage pain and inflammation.
• Corticosteroid injections for severe or persistent symptoms.
• Gradual return to activity under medical guidance.

Prognosis and Follow-Up

Most cases of psoas tendinitis improve with conservative treatment, though recovery time varies. Follow-up may involve monitoring pain levels, range of motion, and functional improvement. Persistent symptoms may require further evaluation to rule out underlying conditions.

Complications

• Chronic pain or reduced mobility if left untreated.
• Tendon degeneration or rupture in severe cases.
• Secondary muscle imbalances due to altered movement patterns.

Lifestyle & Prevention

• Maintain proper posture during prolonged sitting or standing.
• Gradually increase activity intensity to avoid overuse.
• Incorporate stretching and strengthening exercises for the hip and core.
• Use ergonomic support during activities involving hip flexion.

When to Seek Professional Help

Seek medical attention if pain is severe, persistent, or worsening; if mobility is significantly limited; or if symptoms interfere with daily activities. Prompt evaluation is recommended for acute trauma or sudden onset of symptoms.

Tips for Medical Coders

Document the clinical findings supporting the diagnosis, including location of pain, aggravating factors, and physical examination results. Ensure the code M76.1 is used when the condition is specifically identified as psoas tendinitis, with clear differentiation from other hip or groin conditions.
