Patrick T. Gomella, MD, MPH

BASICS

DESCRIPTION

• Osteitis pubis is a painful sterile inflammatory condition affecting the pubic symphysis

– Most commonly seen in athletes

• First described with suprapubic surgery and remains a potential complication of pelvic procedures

EPIDEMIOLOGY

Incidence

• Overall incidence in nonathlete populations unknown

– 0.16% in procedures using bone anchors

Prevalence

Overall prevalence in nonathlete populations unknown

RISK FACTORS

• Invasive pelvic procedures

– Several urologic procedures implicated

Radical prostatectomy

Prostate cryotherapy

TRUS Bx of prostate

TURP

Retropubic urethropexy: Specifically Marshall–Marchetti–Krantz procedure

Sling procedures

Pelvic radiation

• Trauma

• Rheumatic disorders

• Pregnancy/parturition

• Overuse syndrome in athletes

Genetics

No known genetic predisposition

PATHOPHYSIOLOGY

• Symphysis pubis is a nonsynovial amphiarthrodial joint at the confluence of the two pubic bones, consisting of an intrapubic fibrocartilaginous disc between thin layers of hyaline cartilage

• Etiology unknown but may be related to periosteal trauma

ASSOCIATED CONDITIONS

• Ankylosing spondylitis

• Rheumatoid arthritis

GENERAL PREVENTION

N/A

DIAGNOSIS

HISTORY

• Inciting event such as a pelvic procedure or trauma

• Insidious onset of suprapubic pain

• Pain radiating to thigh adductors, lower abdomen, perineum

• Pain worse when walking or when rising from a seated position (1)[C]

PHYSICAL EXAM

• Point tenderness over pubic symphysis

• Waddling gait

• Low-grade fever

• Increased pain with coughing or Valsalva

• Painful hip abduction

DIAGNOSTIC TESTS & INTERPRETATION

ALERT

Must rule out osteomyletis, especially in postoperative patients.

Lab

• Not generally required to make diagnosis

• May see moderate leukocytosis and an increased erythrocyte sedimentation rate (2)[C]

Raised levels of acute phase proteins (fibrinogen, C-reactive protein), and increased erythrocyte sedimentation rate are more suggestive of osteomyelitis

Imaging

• Pelvic radiograph

– Typically normal in acute phase

– Articular surface erosion, sclerosis, osteophyte formation

• Scintigraphy

– Increased uptake around pubic symphysis

• Symphysogram of joint

– Extravasation of contrast material

– Diagnostic and therapeutic

• Magnetic resonance imaging (MRI) most sensitive and considered gold standard

– Acute (<6 mo): Bone marrow edema, fluid in joint, periarticular edema

– Chronic (>6 mo): Subchondral sclerosis/resorption, bony margin irregularities, osteophytes (3)[C]

Diagnostic Procedures/Surgery

• Symphysogram of joint

– Pain on injection of contrast diagnostic (4)[C]

– Generally replaced by MRI

• Aerobic/anaerobic culture of joint aspirate to rule out infection if clinically indicated

Pathologic Findings

Sclerotic changes in bony architecture and degeneration of hyaline cartilage with normal periosteum (5)[C]

DIFFERENTIAL DIAGNOSIS

• Osteomyelitis (the most critical)

• Neoplasia of pelvic rami

• Bony metastases

• Pubic osteolysis

• Sports hernia (athletic pubalgia, sportsman’s hernia)

• Adductor strain

• Muscle tears

• Avulsion injuries

• Stress fractures

• Tears of acetabular labrum

TREATMENT

GENERAL MEASURES

• Rest, heat, or ice

• Physical therapy to strengthen pelvic girdle can be considered

MEDICATION

First Line

• Nonsteroidal anti-inflammatory

– Ibuprofen 200–800 mg 2–4×/d (max dose 2.4 g/d)

– Naproxen 250–500 mg 2×/d (max dose 1.5 g/d for limited time)

• Cyclooxygenase-2 (COX-2) inhibitor

– Celecoxib 100–200 mg 1–2×/d

– Adverse CV events noted with COX-2 inhibitors, use lowest effective dose for shortest duration possible

Second Line

• Oral glucocorticoids such as prednisone if local glucocorticoid injections fail

– Typical short course (ie, 60 mg for 5 days)

– Can use a taper dose

SURGERY/OTHER PROCEDURES

• Glucocorticoid injection in joint may be useful for cases refractory to rest and NSAIDs (4)[C]

– Any steroid preparation can be used based on provider preference

Include an adjuvant anesthetic

• Various surgical techniques can be used for cases refractory to medical management

– Curettage

– Wedge resection

– Wide resection

– Arthrodesis

• If bone anchors are in place, their removal may be necessary

ADDITIONAL TREATMENT

Radiation Therapy

Has been attempted in the past with mixed results, but not recommended due to risk of neoplasia

Additional Therapies

• Cryotherapy, ultrasound therapy, laser therapy, and electric stimulation have been used with variable success in athletic osteitis pubis

– No data on success of these modalities for nonathlete populations

• Anticoagulant therapy with heparin has been suggested as a possible treatment in a postoperative setting with some minimal success

Complementary & Alternative Therapies

Physical therapy

ONGOING CARE

PROGNOSIS

• Typically a drawn out and variable clinical course

– Symptoms can last several months to several years

– Operative procedures may be needed in 5–10% of cases

COMPLICATIONS

• Wedge or wide resection of pubic symphysis—risk of posterior instability of pelvic girdle leading to damage to sacroiliac joints

• Arthrodesis—risk of nonunion or death of bone graft site requiring additional surgery

FOLLOW-UP

Patient Monitoring

Follow-up depends on patient symptomatology and procedures obtained

CLINICAL/SURGICAL PEARLS

• Osteitis pubis pain and osteomyelitis pain worse when walking or when rising from a seated position.

• Essential to rule out osteomyelitis as a more significant cause.

• Rarely osteitis pubis and osteomyelitis of the pubis can coexist.

• To distinguish between osteomyelitis and osteitis pubis, a biopsy and culture of the affected area are necessary.

• Suspect the condition in a urologic patient where the pubic symphysis has been involved in urologic surgical intervention such as bone anchors or sling procedures.
