Elbow joint: diseases, diagnosis and therapy

Anatomy of the elbow joint: the interaction

The elbow is a complex joint complex made up of three sub-joints: the humeroulnar (bending/stretching), the humeroradial and the proximal radioulnar joint (rotational movements of the forearm). A common joint capsule with a synovial membrane encloses the structures and produces synovial fluid that nourishes the hyaline cartilage and reduces friction.

• Joint partners: upper arm bone (humerus), ulna (ulna), radius (radius)
• Articular cartilage: smooth, shock-absorbing layer on the joint surfaces
• Capsule and ligaments: among others Stabilize the ulnar collateral ligament complex (MCL) and radial collateral ligament complex (LCL).
• Synovia: Joint fluid for lubrication and nutrition
• Nearby structures: bursa, tendon attachments, nerve course - clinically relevant, even if not intra-articular

Disturbances in the finely tuned system of cartilage, capsule, ligaments and bones lead to pain, swelling, restricted movement or instability.

Typical symptoms of joint problems

• Pain on exertion and at rest, often localized internally or externally
• Stiffness in the morning or after periods of rest
• Swelling/feeling of warmth (indication of inflammation)
• Restriction of bending, stretching and turning (pronation/supination)
• Snapping, rubbing (crepitation) or blocking due to free joint bodies
• Feeling of instability after injury or ligament damage

Warning signs such as acute, severe pain after trauma, pronounced swelling, fever, pain at night when resting or rapidly increasing restriction of movement should be clarified promptly by a doctor.

Common diseases of the elbow joint

The spectrum ranges from wear and tear and overload to inflammatory or post-traumatic changes. You can find more detailed information on the linked subpages.

• Elbow osteoarthritis: Wear and tear of cartilage, often after previous injuries or chronic overuse
• Rheumatoid arthritis: autoimmune inflammation of the synovial membrane with capsule and cartilage involvement
• Acute or chronic joint inflammation (arthritis): infectious, crystal-induced forms (e.g. gout/pseudogout) or reactive
• Free joint bodies: detached cartilage/bone fragments, lead to blockages and snapping phenomena
• Cartilage damage/osteochondral lesions: localized defects, e.g. B. at the capitulum humeri
• Joint instability of the elbow: after ligament injuries or dislocations, with tipping into valgus/varus
• Post-traumatic conditions: axial deviations, step formation, heterotopic ossifications

Special forms sometimes occur in children and adolescents (e.g. osteochondritis dissecans). In adults, degenerative, inflammatory and post-traumatic causes are the main causes.

Causes and risk factors

• Previous injuries: fractures, dislocations, ligament lesions with later development of osteoarthritis
• Occupational/crushed exposure: repetitive heavy loads, vibration, overhead work
• Sports overload: throwing, racket and strength sports (valgus/varus stress, hyperextension)
• Systemic factors: autoimmune diseases, metabolism (gout), diabetes, smoking
• Biomechanical causes: misalignments, mobility deficits of the shoulder/wrist
• Age and genetic predisposition: influence on cartilage quality and regeneration

Diagnostics: structured and targeted

The evaluation begins with anamnesis (onset of symptoms, progression, stress profile, previous illnesses/medications) and a physical examination with functional testing.

• Inspection/palpation: swelling, warmth, tenderness, effusion
• Range of motion: active and passive flexion/extension, pronation/supination
• Stability tests: Valgus/varus stress, moving valgus stress test
• Imaging: X-ray (joint space, osteophytes, free bodies), ultrasound (effusion, synovitis), MRI (cartilage, bone marrow, ligaments), CT (bone geometry, free bodies)
• Laboratory/fluid analysis: inflammation levels, uric acid; Joint puncture if infection or crystal arthropathy is suspected

Depending on the question, functional analysis, documented ROM measurements and progress checks are used. Injection diagnostics can provide information about the source of pain in selected cases.

Conservative therapy: basis of treatment

In orthopedics, conservative therapy has priority. The aim is to reduce pain, calm inflammation, improve mobility and ensure joint function.

• Education & stress control: temporary reduction of triggering activities, ergonomic adjustments
• Medication: anti-inflammatory painkillers in low effective doses and for as short a period as possible; Prefer topical preparations, pay attention to stomach and kidney tolerance
• Physiotherapy: joint mobilization, capsular stretching, neuromuscular training, coordination; Integration of shoulder blade and trunk stability
• Aids: temporary bandages/splints for calming; targeted, time-limited use
• Cold/warm: cold for acute inflammation, warm for tension
• Weight and lifestyle factors: quitting smoking, sleep, anti-inflammatory nutritional principles

For inflammatory rheumatic diseases, basic therapy is carried out in collaboration with rheumatology (e.g. DMARDs). We provide orthopedic support with physiotherapy, infiltrations and joint protection.

Injections and minimally invasive procedures

Injections can specifically relieve symptoms and improve function. The selection and implementation are carried out individually and after information about the benefits and risks.

• Intra-articular corticosteroids: short-term inflammatory control, limited frequency
• Hyaluronic acid: visco-supplementing; Mixed study data, weigh benefits individually
• PRP (platelet-rich plasma): regenerative procedure with heterogeneous evidence; selectively and according to indication
• Ultrasound or X-ray assisted puncture/irrigation for effusion; Diagnostic/therapeutic if infectious is suspected
• Arthroscopy: minimally invasive for the removal of free joint bodies, synovectomy, capsule release, smoothing of osteophytic constrictions; only if there is a suitable indication

None of these procedures guarantee freedom from symptoms. The key success factor is the combination of appropriate indications, technology and consistent follow-up treatment.

Operational options – when do they make sense?

If conservative measures are insufficiently helpful and the quality of life is significantly reduced, surgical procedures can be considered. The selection depends on the findings, age, activity level and objectives.

• Arthroscopic/open debridements: removal of free bodies, osteophytes, capsule solution for painful impingement/stiffness
• Ligament reconstruction in cases of relevant instability (e.g. MCL/LCL) after conservative therapy has been exhausted
• Cartilage/bone procedures: microfracture, osteochondral transplantation in selected cases
• Prosthetic joint replacement (elbow TEP): last resort for advanced osteoarthritis with a low load profile
• Interposition arthroplasty or conversion osteotomies in specialized situations

Indications for surgery are discussed carefully and realistically. Rehabilitation, rest and targeted physiotherapy are essential for the result.

Self-help and training: what you can do yourself

• Maintain mobility: gentle bending/stretching and twisting movements within the pain limit several times a day
• Dose loads: slowly increase impact and throwing loads, plan breaks
• Adjust the workplace ergonomically: forearm support, neutral wrist angle, frequent micro-breaks
• Local measures: 10-15 minutes of cold for acute irritation; Heat for muscle relaxation
• Think holistically: have shoulder/torso stability, posture and technique checked
• Treat concomitant illnesses: e.g. B. Stop gout, reduce smoking

Sport and work: return safely

The return will take place gradually. First, pain-free everyday life and full mobility, then targeted strength and coordination, then sport-specific stress. Technical training and adequate regeneration are key.

When should you seek medical advice?

• Acute pain after a fall/injury, deformity, significant limitation of movement
• Pain at rest, pain at night, or persistent swelling/warmth
• Fever or general symptoms of joint problems
• Repeated blockages, snapping, or marked stiffness
• Feeling of instability or buckling under load
• Known rheumatic disease with new elbow involvement

Course, prognosis and prevention

The prognosis depends on the cause, severity and level of therapy. Many complaints can be significantly improved conservatively. Chronic changes such as osteoarthritis cannot be “cured”, but their progression can be positively influenced.

• Early clarification if symptoms persist
• Targeted training for mobility, strength and control
• Control load, optimize technique, plan breaks
• Treat comorbidities, reduce risk factors
