Inflammation of the joints (arthritis) in the elbow

Anatomy of the elbow – why inflammation is so painful

The elbow consists of three joints: the humeroulnar joint, humeroradial joint and proximal radioulnar joint. A common joint capsule with mucous membrane (synovium) covers the joint surfaces. The synovium produces synovial fluid that nourishes the cartilage and lubricates movement. If this mucous membrane becomes inflamed, increased fluid formation (effusion), swelling and pain occurs.

• Capsule and synovium: central structures in arthritis
• Strong nerve supply: explains the pronounced pain
• High tendency to stiffness: avoid prolonged immobilization, mobilize early

What is Elbow Arthritis?

Arthritis is an inflammatory disease of the interior of the joint. It can occur infectious (bacterial), crystal-related (e.g. gout), autoimmune (e.g. rheumatoid arthritis, psoriatic arthritis), reactive after infections, metabolic or post-traumatic. If left untreated, long-term inflammation can damage cartilage and bones.

• Acute arthritis: hours to days, often severe pain and redness
• Chronic arthritis: gradual progression with morning stiffness and recurring attacks
• Monoarthritis: only the elbow affected; Oligo/polyarthritis: multiple joints at the same time

Typical symptoms

• Pain at rest and under stress, often throbbing
• Swelling, warmth, occasionally redness
• Restriction of movement, v. a. Extension and flexion inhibition
• Morning stiffness >30 minutes (common in inflammatory rheumatic forms)
• General symptoms of infection: fever, feeling sick

Causes and risk factors

• Infectious (septic) arthritis: bacteria in the joint – acute emergency
• Crystal arthropathies: gout (uric acid crystals), pseudogout/CPPD
• Autoimmune: rheumatoid arthritis, psoriatic arthritis, spondyloarthritis
• Reactive after infections (e.g. urinary/intestinal tract)
• Post-traumatic: after contusion/sprain with synovitis
• Degenerative: inflammatory attacks associated with osteoarthritis
• Risk factors: previous joint injections/surgery, diabetes, immunosuppression, high uric acid, psoriasis

Differential diagnoses: Not all elbow swelling is arthritis

• Bursitis (olecranon bursitis): swelling over the tip of the ulna, often without joint involvement
• Elbow joint arthrosis without florid inflammation
• Tendon attachment irritation (tennis/golfer elbow) – outside the joint
• Free joint bodies, cartilage damage, osteochondritis dissecans
• Crystal deposits in soft tissues (tophi)
• Skin or soft tissue infection (cellulitis) without intra-articular involvement

Diagnostics: Differentiate safely, treat safely

The aim is to quickly identify or rule out infectious arthritis and to classify the cause of the inflammation. Joint puncture is the standard procedure for unclear, painful swelling, provided there are no contraindications.

Important: A puncture relieves painfully tense joints and provides crucial information. Infection must be reliably ruled out before intra-articular corticosteroid injections.

Conservative therapy – our first step

Treatment depends on the cause, activity and comorbidities. Basic principles: control inflammation, relieve pain, maintain mobility, treat the cause.

• Short-term protection: Immobilization in the functional position for a maximum of a few days to avoid stiffness
• Cold in the acute phase, if chronic stiffness may be warm
• Anti-inflammatory drugs (NSAIDs) at the lowest effective dose; local gels as an option
• Joint aspiration for severe effusion for pain relief and diagnosis
• Physiotherapy and occupational therapy: early functional mobilization, joint protection, everyday adaptation, avoidance of end positions
• Treatment of the underlying disease: e.g. B. Uric acid lowering in gout, DMARDs/biological therapies in collaboration with rheumatology in rheumatoid arthritis
• Ergonomic adjustments at work/sports, load control

Gout flare-up: short-term colchicine or NSAID; Check uric acid reduction after the attack has subsided. CPPD is treated symptom-based.

Corticoid injection: In non-infectious arthritis, an intra-articular injection under sterile conditions and ideally ultrasound-targeted can reduce discomfort. It is indicated when conservative measures are not sufficient. A prior infection clarification is mandatory.

Invasive and surgical options – targeted and with a sense of proportion

• Septic arthritis: immediate hospital treatment, antibiotics, usually surgical irrigation/debridement - this is an emergency.
• Arthroscopic synovectomy: for treatment-refractory, non-infectious synovitis (e.g. rheumatoid arthritis) to reduce inflammatory activity.
• Radio synoviorthesis (RSO): in selected cases with chronic synovitis and after conservative options have been exhausted; Implementation with nuclear medicine cooperation. Not used in case of infection.
• Regenerative procedures: PRP or hyaluronic acid on the elbow are discussed individually; the evidence is limited and heterogeneous at the elbow. Careful indication is a prerequisite.

The aim of all measures is to preserve the joint and restore function. Surgical procedures are only considered after conservative options have been exhausted and the benefits and risks have been clearly weighed up.

Self-help and everyday strategies

• Short-term relief with a forearm sling, but move gently several times a day
• Cold packs 10-15 minutes for swelling; Protect skin
• Light movement exercises in the pain-free area, no jerky end movements
• Adjust the workplace: forearm support, changing positions, breaks
• Note down the triggers (exertion, diet for gout) and discuss them with the treatment team
• Adequate fluid intake and balanced diet; If you have gout, reduce foods rich in purines and alcohol

Course and prognosis

The prognosis depends on the cause and treatment time. Acute, non-infectious arthritis often resolves within days to weeks with targeted therapy. Chronic inflammatory diseases require a long-term disease control strategy. In gout, flare-ups can be significantly reduced by controlling uric acid. Septic arthritis can destroy cartilage in a short period of time - every hour counts.

• Early diagnosis protects cartilage and mobility
• Regular follow-up checks for chronic inflammation
• Consistent stretching and exercise programs prevent stiffness

Warning signs: when to clarify immediately?

• Suddenly severe pain with massive swelling, redness and warmth
• Fever, chills, pronounced feeling of illness
• New joint inflammation under immunosuppression or after injection/surgery
• Severe pain at rest, rapid deterioration within hours

These signs may indicate a joint infection. Please see a doctor immediately – if necessary at the rescue center.

Prevention: Avoid flare-ups of inflammation

• Consistent treatment of underlying diseases (e.g. rheumatism, gout)
• Exercise dosage in sport and work, plan breaks
• Protection against skin injuries and infections, especially if the joint is previously damaged
• Healthy lifestyle: weight control, quitting smoking, getting enough sleep

Our approach in Hamburg

In our orthopedic specialist practice at Dorotheenstrasse 48, 22301 Hamburg, we start with elbow arthritis with a structured anamnesis, physical examination and - if necessary - imaging diagnostics and joint aspiration. We prioritize conservative measures, clarify causes in a differentiated manner and, if necessary, coordinate interdisciplinary treatment (e.g. rheumatology, nuclear medicine).

• Conservative first: control inflammation, maintain mobility
• Safe indication for injections – rule out infection beforehand
• Transparent information about benefits, limits and alternatives
• Follow-up care with clear exercise and stress recommendations

Related to osteoarthritis, cartilage damage and instability

Inflammation can occur as a flare-up in degenerative changes (osteoarthritis) and increase symptoms. Free joint bodies or cartilage damage cause recurring irritation. Instabilities lead to overloading of the synovium. A cause-based therapy takes these connections into account in order to avoid further attacks.
