Understanding Adductor Bursitis
Adductor bursitis is a less common but important cause of inner groin and thigh pain, resulting from inflammation of the small fluid-filled sac cushioning the adductor tendons near their attachment to the pelvis.
While it shares some overlap with adductor tendinitis, adductor bursitis specifically involves the bursa rather than the tendon fibers themselves, and distinguishing between the two guides more precise, effective treatment.
Symptoms of Adductor Bursitis
Do not ignore these physical red flags indicating bursal inflammation in the medial thigh:
Deep Pubic Bone Tenderness
Focal, pinpoint pain and tenderness felt deep in the groin near the pubic bone attachment.
Compression & Sitting Pain
Pain worsening with direct seating pressure, particularly when sitting on hard unpadded chairs.
Adduction Strain
Discomfort aggravated by squeezing legs together, side-stepping, or rotational hip cutting movements.
Localized Swelling & Heat
Mild palpable swelling, bursal distension, and warmth localized along the proximal inner thigh.
Causes of Adductor Bursitis
Inner thigh bursal inflammation is triggered by friction, direct trauma, and biomechanical imbalance:
- Repetitive Friction: High-demand lateral cutting, pivoting, and kicking in soccer, hockey, or martial arts.
- Direct Impact Trauma: Blunt force trauma or falls landing directly on the medial groin and pubic rami.
- Prolonged Pressure: Repetitive mechanical rubbing and saddle compression during distance cycling or horseback riding.
- Pelvic Biomechanical Imbalance: Core weakness, gluteal inhibition, or leg length discrepancies overloading the adductor ring.
Treatment & Rehabilitation Approach
Adductor bursitis responds exceptionally well to structured conservative modalities and staged return-to-sport:
Conservative De-loading
Pausing provocative cutting activities, ice therapy in acute phases, gentle non-aggressive stretching, and oral anti-inflammatory support.
Guided Injections & Progression
Ultrasound-guided corticosteroid bursal injection for recalcitrant cases, followed by progressive isometric and eccentric adductor re-strengthening.
How Adductor Bursitis Is Diagnosed
Our structured 4-tier clinical diagnostic protocol evaluates bursal distension, adductor squeeze provocation, differential sports hernia screening, and dynamic musculoskeletal imaging.
1. History & Sports Biomechanics Audit
Detailed screening of cutting motions, direct groin trauma, saddle friction, and onset timeline.
- Sport-Specific Cutting Audit: Inquiring about lateral acceleration, pivoting, and kicking in soccer, hockey, or rugby.
- Bicycle & Equestrian Saddle Audit: Tracking hours spent cycling or riding with sustained saddle pressure on the inner thigh.
- Acute vs Overuse Onset: Documenting blunt trauma blow to groin vs insidious gradual friction buildup.
- Pinpoint Pain Localization: Asking patient to point to localized pain spot at the pubic bone (bursa marker).
- Hard Surface Sitting Intolerance: Documenting immediate deep groin ache when sitting on unpadded stools or wood.
- Stairs & Side-Stepping Aggravation: Tracking sharp twinges when taking two steps at a time or stepping out of cars.
- Sleep Position Disturbance: Evaluating pain when sleeping on side without pillow between knees (adductor stretch).
- Warm-Up Pattern: Noting if pain improves slightly after warming up but returns intensely post-exercise.
- Prior Adductor Strain History: Screening for previous inner thigh tears creating residual scar tissue.
- Footwear & Surface Review: Checking artificial turf cleats or running shoes lacking medial support.
- Medication Response Review: Assessing symptom reduction after trial of oral anti-inflammatory drugs.
- Ice vs Heat Response: Documenting whether acute cold application rapidly calms deep groin throbbing.
- Previous Physical Therapy Review: Evaluating response to stretching (aggressive stretching often worsens bursitis).
- Pain Visual Analog Score (VAS): Recording rest, walking, and sport-related groin pain numbers.
- HAGOS Functional Outcome Index: Scoring Copenhagen Hip and Groin Outcome Score baseline.
2. Differential Groin & Neuro Screening
Screening for sports hernias, hip labral tears, obturator nerve entrapment, and pubic osteitis.
- Tendinitis vs Bursitis Differentiation: Tendinitis shows diffuse tendon length tenderness; bursitis is focal and cystic.
- Athletic Pubalgia (Sports Hernia) Screen: Checking pain during resisted abdominal crunch or cough/Valsalva.
- Inguinal Hernia Physical Exam: Palpating superficial inguinal ring for palpable impulse or true visceral cough bulge.
- Osteitis Pubis Exclusion: Checking bilateral tenderness directly over pubic symphysis joint line.
- Obturator Nerve Entrapment Screen: Testing for burning medial thigh numbness and adductor muscle wasting.
- Femoral Acetabular Impingement (FAI): FADIR maneuver checking deep anterior hip groin pinch.
- Acetabular Labral Tear Screen: Checking hip click, catching, or giving-way sensations.
- Femoral Neck Stress Fracture Screen: Fulcrum test and inability to hop on single leg without severe groin pain.
- Lumbar Radiculopathy (L1-L2) Rule-Out: Assessing upper lumbar disc referral to groin dermatome.
- Iliopsoas Bursitis Differentiation: Palpating anterior groin lateral to femoral artery (psoas bursa).
- Genitourinary / Testicular Audit: Ruling out epididymitis, varicocele, or gynecologic pelvic pain referral.
- Septic Bursitis Red-Flag Check: Screening for high fever, spreading erythema, or fluctuant abscess signs.
- Vibration Sense & Reflex Integrity: Confirming normal patellar reflex and intact sensation.
- Urgent Urological / Surgical Triage: Fast-track referral for incarcerated hernias or testicular emergencies.
3. Physical Palpation & Provocation Exam
Direct bursal palpation, resisted adductor squeeze tests at 0°/45°, and flexibility metrics.
- Focal Adductor Bursa Palpation: Identifying point tenderness deep between pectineus and adductor longus tendon origin.
- Bursal Swelling / Fullness Check: Feeling for localized boggy swelling compared to asymptomatic side.
- Adductor Squeeze Test at 0° (Knees Straight): Squeezing sphygmomanometer/fist between ankles reproducing groin pain.
- Adductor Squeeze Test at 45° (Hook-Lying): Squeezing fist between knees testing adductor longus and bursal shear.
- Passive Hip Abduction Stretch: Gently opening thigh to end-range provoking bursal stretch compression.
- Resisted Adductor Strength (0-5 Scale): Documenting pain inhibition weakness during manual muscle testing.
- Patrick’s (FABER) Test: Evaluating posterior and medial groin pain response during figure-4 hip position.
- Pelvic Alignment & Leg Length Check: Measuring true anatomical leg length discrepancy causing uneven load.
- Gluteus Medius Strength Test: Testing hip abductor endurance (abductor weakness overloads adductors).
- Core Muscle Stability Assessment: Single-leg bridge and plank testing pelvic ring load transfer.
- Thomas Test for Hip Flexors: Checking psoas and rectus femoris tightness altering pelvic tilt.
- Active Straight Leg Raise (ASLR): Testing functional pelvic stability and sacroiliac load transfer.
- Physical Baseline Record: Logging squeeze test pressure (mmHg) and abduction range for rehab tracking.
4. Ultrasound, MRI & Rehab Roadmap
High-resolution dynamic ultrasound, pelvic MRI, guided bursal injections, and return-to-sport staging.
- High-Resolution Musculoskeletal Ultrasound: Visualizing anechoic/hypoechoic fluid distension inside adductor bursa.
- Power Doppler Ultrasound Assessment: Identifying active hypervascularity and acute bursal synovial wall thickening.
- Tendon Integrity Ultrasound Check: Confirming intact adductor longus/brevis fibers without high-grade tearing.
- Pelvis & Hip MRI (T2/STIR Sequences): Evaluating hyperintense fluid signal between adductor tendons and pubic bone.
- Bone Marrow Edema Rule-Out: Checking absence of subchondral pubic bone edema to exclude active osteitis pubis.
- Pelvic AP Radiograph: Ruling out pubic bone avulsion fractures, calcific tendinopathy, or hip dysplasia.
- Diagnostic Local Anesthetic Block: Ultrasound-guided bursal infiltration confirming immediate pain elimination.
- Corticosteroid / PRP Bursal Injection: Targeted anti-inflammatory or regenerative therapy for recalcitrant cases.
- Staged Conservative Rehab Protocol: Phase 1 (rest/ice), Phase 2 (isometric squeeze), Phase 3 (dynamic loading).
- Copenhagen Adductor Exercise (CAE): Introducing progressive eccentric adductor strengthening once pain subsides.
- Bicycle & Saddle Modification Plan: Recommending cutout saddles, wider bike seats, and padded shorts.
- Multi-Specialist Sports Medicine Review: Collaborative sports physician, physiotherapist, and orthotist care audit.
- Digital Archiving: Secure storage of ultrasound stills and squeeze pressure graphs in patient portal.
- Final Return-to-Sport Clearance: Passing pain-free 100% maximal squeeze test and functional sprint cutting drills.
