Snapping Hip

The psoas major is part of the iliopsoas muscle group, which includes the iliacus and psoas minor. This muscle originates from the lumbar spine and attaches to the femur, playing a crucial role in:

• Hip flexion (bringing the knee toward the chest)
• Lumbar spine stabilization
• Posture maintenance
• Walking, running, and cycling movements

When the psoas muscle becomes tight or overworked, it can lead to pain and dysfunction, contributing to psoas tendonitis and other hip-related conditions.

Several factors can contribute to inflammation of the psoas tendon, including:

• Overuse injuries: Repetitive hip flexion in activities like running, cycling, and kicking sports.
• Muscle imbalances: Weak glutes or tight hip flexors can place excessive strain on the psoas tendon.
• Poor posture: Prolonged sitting can shorten the psoas muscle, leading to tightness and irritation.
• Biomechanical issues: Leg length discrepancies, flat feet, or improper running form can increase stress on the tendon.
• Previous hip injuries: Trauma or surgery affecting the hip can lead to compensatory movement patterns that stress the psoas tendon.

The symptoms of psoas tendonitis can range from mild discomfort to severe pain, impacting daily activities. Common signs include:

• Pain in the front of the hip or groin
• Tenderness deep within the hip joint
• Clicking or snapping sensation in the hip
• Pain with hip flexion activities (running, climbing stairs, or lifting the leg)
• Tightness in the lower back and pelvis
• Difficulty standing up straight after prolonged sitting

Diagnosing psoas tendonitis requires a comprehensive assessment that includes:

Physical Examination:

Tests like the Thomas test and resisted hip flexion test help identify psoas tightness and pain.

Imaging Tests:

• Ultrasound: Evaluates tendon inflammation and movement abnormalities.
• MRI: Provides detailed images of soft tissue structures to rule out labral tears or hip impingement.
