Osteitis Pubis
Lower LimbOverview
Osteitis pubis is an inflammatory condition of the pubic symphysis and surrounding bone, commonly occurring in athletes involved in activities requiring repetitive kicking, twisting, or rapid acceleration/deceleration. The condition results from biomechanical stress and microtrauma to the pubic joint and associated musculature, presenting with chronic groin pain that significantly impacts athletic performance.
Pathophysiology
Osteitis pubis develops through cumulative microtrauma to the pubic symphysis caused by repetitive stress from adductor muscle pull, rectus abdominis tension, and dynamic hip instability. This leads to inflammatory changes in the symphyseal joint, surrounding bone, and associated soft tissues. Underlying biomechanical dysfunction—including hip muscle imbalances, core instability, and altered pelvic mechanics—perpetuates the inflammatory cycle and prevents healing.
Patient Education
Osteitis pubis requires a comprehensive approach addressing both local inflammation and the underlying biomechanical dysfunction causing repetitive stress; early intervention focusing on load management and muscle balance is essential to prevent chronic pain patterns.
Typical Presentation
Site
Pubic symphysis and medial groin region, often bilateral; pain may radiate into lower abdomen or medial thigh
Quality
Dull, aching pain with inflammatory characteristics; may describe as sharp with certain movements
Intensity
Moderate to severe (6-8/10); typically worsens with activity and improves with rest, though morning stiffness is common
Aggravating
Adduction against resistance, kicking, running, twisting and turning, rapid acceleration/deceleration, sit-ups, climbing stairs, prolonged standing on one leg
Relieving
Rest, ice application, anti-inflammatory medication, gentle stretching of adductors, core stabilization work, activity modification
Associated
Hip adductor tightness and tenderness, lower abdominal pain, hip flexor tightness, reduced hip internal rotation, core muscle weakness, altered pelvic biomechanics, pain with provocative tests (adduction squeeze test)
Orthopaedic Tests
Palpation of the Pubic Symphysis
Procedure
Patient supine or seated. Palpate the pubic symphysis and surrounding adductor musculature directly over the symphyseal joint. Apply gentle pressure to elicit tenderness.
Positive Finding
Localized tenderness directly over the pubic symphysis or medial adductor insertion
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Highly suggestive of pubic symphysis pathology; cornerstone of clinical assessment. Tenderness localizes inflammation to the symphysis itself.
Adductor Squeeze Test (Adductor Longus Provocation)
Procedure
Patient supine, hips flexed to 45° and knees flexed to 90°. Place a pillow or rolled towel between the knees. Ask patient to squeeze the object with maximum effort for 5 seconds.
Positive Finding
Pain at the medial groin, pubic symphysis, or lower abdomen during or immediately after squeezing
Sensitivity / Specificity
71% / 86%
Delporte et al., 2017, British Journal of Sports Medicine
Interpretation
Positive test suggests adductor-related groin pain, commonly associated with osteitis pubis. Pain with adductor contraction reflects symphyseal stress and musculotendinous inflammation.
Single Leg Stance with Trunk Flexion
Procedure
Patient stands on one leg while attempting to touch their toes. Observe for pelvic tilt and note reproduction of groin or symphyseal pain.
Positive Finding
Pain in the pubic region or inability to maintain neutral pelvis; reproduction of osteitis pubis symptoms
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Positive test indicates instability across the pubic symphysis and increased stress on the joint during unilateral loading. Common in osteitis pubis due to core and adductor weakness.
Resisted Hip Adduction (Standing or Supine)
Procedure
Patient supine or standing. Place examiner's hand on medial thigh proximal to knee. Resist patient's adduction effort while monitoring for pain at the pubic symphysis or medial groin.
Positive Finding
Sharp or reproducing pain in the pubic symphysis region or medial groin during resisted adduction
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Positive result indicates adductor and rectus abdominis strain contributing to symphyseal dysfunction. Reflects musculotendinous irritation at or near the pubic attachment.
Resisted Hip Flexion with Adduction (Flexion–Adduction Test)
Procedure
Patient supine, hips flexed to 45°. Resist combined hip flexion and adduction. Monitor for pain localized to the symphysis or medial lower abdomen.
Positive Finding
Reproduction of pain at the pubic symphysis or proximal medial adductor region
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Combines the stress of both rectus abdominis and adductor longus, increasing provocation of symphyseal inflammation. Highly specific to osteitis pubis when positive.
Pelvic Distraction Test
Procedure
Patient supine. Examiner places hands on the anterior superior iliac spines and applies gentle separation (lateral distraction) of the pelvis. Assess for pain relief or reproduction at the symphysis.
Positive Finding
Pain relief or reduction in symphyseal tenderness with distraction; alternatively, pain with compression (reverse test) suggests symphyseal pathology
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Positive distraction test (pain relief) may indicate symptomatic unloading of the pubic symphysis, supporting diagnosis of osteitis pubis. Compression that reproduces pain further confirms symphyseal involvement.
⚠ Red Flags

Osteopathic Techniques
Region
Pubic symphysis and surrounding soft tissues
Technique
Soft Tissue
Rationale
Gentle soft tissue mobilization to adductor longus, gracilis, and rectus abdominis attachments reduces muscle tension and pain while improving local circulation without aggravating the inflamed symphysis
Region
Hip joint and surrounding muscles
Technique
MET
Rationale
Muscle Energy Techniques applied to hip adductors, flexors, and external rotators address muscle imbalance and restore normal hip mechanics, reducing aberrant forces transmitted through the pubic symphysis
Region
Lumbosacral and pelvic regions
Technique
Articulation
Rationale
Gentle articulation of sacroiliac joints and lumbar spine corrects associated pelvic dysfunction and abnormal load distribution that perpetuates symphyseal stress
Region
Adductor and inguinal region
Technique
Functional
Rationale
Functional osteopathic techniques support optimal positioning of pelvic structures and adductor muscle-tendon units during loading, reducing repetitive microtrauma
Region
Anterior pelvic and lower abdominal region
Technique
Soft Tissue
Rationale
Release of rectus abdominis and associated anterior pelvic fascia reduces superior traction on the pubic symphysis while improving fascial continuity and load distribution
Region
