Hip FAI Impingement: Deep Hip Pain in Young Basketball Players

Introduction

Femoroacetabular Impingement (FAI) is a common problem among young athletes, particularly basketball, ice hockey, and soccer players. It causes catching and pain deep in the hip, affecting cutting, squatting, and pivoting movements.

This article summarizes the types, diagnosis, and conservative treatment strategies for FAI, and discusses the timing of surgical intervention.

Classification of Types

Type	Structural Features	Common Population
Cam	Bony bump at the femoral head-neck junction	Males, 20–30 years old
Pincer	Overcoverage of the acetabular rim	Females, middle-aged
Mixed	Both present	Most clinical cases

Pathophysiology

Repetitive impingement causes:

• Acetabular labral tear
• Cartilage degeneration
• Increased risk of osteoarthritis

Squatting, cutting, and low defensive stances in basketball players all trigger impingement.

Symptoms

• Deep anterior hip pain (C-sign)
• Difficulty rising after prolonged sitting
• Catching during cutting, squatting, and direction changes
• Referred pain to the lateral buttock

Assessment

• FADIR test: hip flexion, adduction, internal rotation
• FABER test: hip external rotation, abduction
• X-ray: alpha angle, CE angle
• MRI arthrogram: labral tear

Treatment Strategy

Conservative treatment first (3–6 months):

1. Movement correction: avoid extreme hip flexion with internal rotation
2. Gluteal strengthening: clamshell, bridge
3. Iliopsoas release
4. Mobility training: 90/90 hip mobility
5. Sport-specific: adjusting squat depth

If conservative treatment fails or there is a significant labral tear, consider hip arthroscopy.

Rehabilitation Timeline

Phase	Duration	Focus
Assessment	Week 1	Movement analysis, strength testing
Early	1–4 weeks	Mobility, gluteal activation
Intermediate	4–12 weeks	Functional training
Advanced	12–20 weeks	Jump shots, cutting movements
Return to play	5–6 months	Full basketball training

Practical Recommendations

• Do not ignore recurrent catching deep in the hip; seek imaging assessment early
• If squatting causes pain, adjusting foot external rotation angle may provide relief
• Perform 5 minutes of hip mobility work before training
• Short-term NSAID use is acceptable during the acute phase
• Discuss hip arthroscopy vs. conservative treatment with an orthopedic sports medicine specialist
• NTSU Sports Science Center and Chang Gung Sports Medicine Center provide comprehensive FAI assessments

Prevention Strategies

• Maintain hip mobility during the season
• Strengthen the gluteus medius and gluteus maximus
• Avoid prolonged training in a single posture
• Incorporate core training to stabilize the pelvis

Conclusion

FAI is an interaction between “structural” and “functional” factors. Although bone morphology cannot be changed, most young basketball players can return to the court without surgery through movement correction and strength training. Seek early comprehensive conservative treatment to avoid progression to the arthritic stage.
