Introduction: Hip pain due to inflammation of the synovium of the hip; Epidemiology . incidence . most common cause of hip pain in the pediatric population

Increased warmth and erythema also suggest inflammation, but these findings are often insensitive, so their absence does not rule out inflammation. Clicking or a feeling that the patella is floating suggests an effusion. This maneuver causes swelling to appear (or be palpable) on the medial side. Finding crystals in synovial fluid confirms crystal-induced arthritis but does not rule out coexisting infection.

Examination of the head, neck, and skin should note any signs of conjunctivitis, psoriatic plaques, tophi, or ecchymoses. Pain without inflammation is usually more safely treated with. Pain that is worse with passive as well as active joint motion on examination, and that restricts joint motion, usually indicates inflammation. Review of systems should seek extra-articular symptoms of causative disorders, including fever (infection, sometimes crystal-induced arthritis), urethritis (gonococcal arthritis or reactive arthritis), rash or eye redness (reactive or psoriatic arthritis), history of abdominal pain and diarrhea (inflammatory bowel disease), and recent diarrhea or genital lesions (reactive arthritis). Prompt drainage, IV antibiotics, and sometimes operative joint lavage may be required to minimize permanent joint damage and prevent sepsis and death.

Injury can affect intra-articular and/or periarticular structures and involve direct injury (eg, twisting during a fall) or overuse (eg, repetitive motion, prolonged kneeling). The most common causes of acute monoarticular pain overall are the following: With injury, a history of trauma is usually present and suggestive. Also, temporal patterns (eg, persistent vs intermittent), associated symptoms (eg, swelling), exacerbating and mitigating factors (eg, activity), and any recent or past trauma to the joint should be noted. X-rays rarely change the diagnosis in acute monarthritis unless fracture is suspected. Involvement of the first metatarsophalangeal joint (podagra) suggests gout but can also result from Symptoms indicating dermatologic, cardiac, or pulmonary involvement suggest disorders that are systemic and more commonly result in polyarticular joint pain. Acute monoarticular pain is sometimes caused by a disorder that characteristically causes polyarticular pain (eg, Inflammation (due to, eg, infection, crystal-induced arthritis, or autoimmune systemic inflammatory disorders) Noninflammatory problems, usually mechanical (eg, trauma, internal derangements) The synovium and joint capsule are major sources of intra-articular pain. Crystals in synovial fluid confirm crystal-induced arthritis but do not rule out coexisting infection. Clinical evaluation should determine whether the joint or periarticular structures are the cause of symptoms and whether there is joint inflammation. Other imaging tests (eg, CT, bone scan, but most often MRI) are rarely necessary acutely but may be indicated for diagnosis of certain specific disorders (eg, osteonecrosis, tumor [see Table: Blood tests (eg, ESR, rheumatoid factor, anti-cyclic citrullinated peptide [anti-CCP] antibody) may help support a clinically suspected diagnosis of a systemic inflammatory disorder (eg, RA). But now that things are starting to settle I thought I’d share my favorite room.

Kocher Criteria for Septic Arthritis - MDCalc
The Kocher Criteria for Septic Arthritis distinguishes septic arthritis from transient synovitis in a child with an inflamed hip.

From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world. X-rays rarely change the diagnosis in acute monarthritis unless fracture is suspected. Physical therapy after the acute symptoms have lessened is useful to increase or maintain range of motion and strengthen adjacent muscles. Testing is often necessary to rule out serious causes and establish the diagnosis. I’ve been moving to a new place and hadn’t had much time or wifi to post.

Arthrocentesis is mandatory to rule out infection in acute monoarticular joint pain with swelling. With some types of bursitis (eg, olecranon, prepatellar), swelling and sometimes erythema may be localized at the bursa. Joint pain that is still unexplained after arthrocentesis and x-ray should be evaluated with MRI to rule out uncommon etiologies (eg, occult fracture, osteonecrosis, pigmented villonodular synovitis). For injuries, the joint is stressed with various maneuvers (as tolerated) to identify disruption of cartilage or ligaments (eg, in the knee, valgus and varus tests, anterior and posterior drawer tests, Lachman test, McMurray test). Injury can affect intra-articular and/or periarticular structures and involve direct injury (eg, twisting during a fall) or overuse (eg, repetitive motion, prolonged kneeling). Pain that originates from the menisci is more likely to be a result of injury. Clicking or a feeling that the patella is floating suggests an effusion. Acute, self-limited, recurrent episodes of monarthritis, most often in the first metatarsophalangeal joint, ankle, or knee (gout) or wrist or knee (pseudogout) Sometimes x-rays for transient hydroxyapatite deposition in calcific periarthritis Acute or subacute onset of pain, swelling, and warmth, commonly with decreased range of motion More frequent in immunosuppressed patients, IV drug users, patients with diabetes or prior antibiotic use, and patients with risk factors for sexually transmitted diseases Prior manifestations of Lyme disease, such as erythema migrans, fever, malaise, and/or myalgias following a tick bite Sometimes obesity, history of joint overuse (eg, in professional athletes), and/or bony enlargement Pain with active joint movement; minimal pain with passive movement and joint compression Point tenderness and sometimes swelling and/or erythema over the bursa, tendon insertion site, or other periarticular structure (eg, fascia); minimal localized tenderness over joint, no effusion Sometimes aspiration of bursal fluid for Gram stain, cell count, and culture Usually large joint effusion in the painful joint, often in a patient with psoriasis Insidious, slowly progressive, and eventually constant pain, usually with joint swelling Acute monoarticular joint pain requires rapid diagnosis because infectious (septic) arthritis requires rapid treatment. A noninflammatory synovial fluid (eg, 1000/µL WBCs) is more suggestive of osteoarthritis or trauma.
