Overload and dysfunction of the elbow

Anatomy: Why the elbow is so vulnerable

The elbow connects the upper arm and forearm via several joint parts (humeroulnar, humeroradial and proximal radioulnar joint). Flexion/extension and rotational movements (pronation/supination) are controlled by powerful muscle groups of the forearm flexors and extensors. Important nerves run through the area: the ulnar nerve on the inside (sulcus ulnaris), the radial nerve with its posterior interosseous branch in the area of ​​the so-called radial tunnel and the median nerve on the front/inside of the forearm. Tendons, fascia and gliding tissue must slide freely under load - if irritation or constriction occurs, pain, numbness or loss of strength arise.

• Ulnar nerve: runs behind the inner bone projection (musician's bone) - sensitive, among other things. for ring and little fingers.
• Radial nerve/posterior interosseous nerve (PIN): motor supply to the extensor muscles, irritation possible in the radial tunnel.
• Median nerve: sensitive, etc. Thumb–middle finger, motor for gripping function; also irritable proximally.
• Tendon attachments: extensor tendon laterally (tennis elbow), flexor tendon medially (golfer's elbow).
• Fascia/slide bearings: crucial for pain-free load transfer and nerve mobility.

What are overload and dysfunction problems?

This refers to complaints that arise not from an acute accident, but from repeated or unfavorable stress. Factors often work together: an irritated tendon (tendinopathy), shortened or tired muscles, fascial tension and, at the same time, mechanical irritation or sliding disorder of a peripheral nerve. This can lead to pain in the epicondyle (inside/outside), tingling in the fingers, loss of strength when gripping or a loss of sensation.

• Muscular-tendinous: Overloaded forearm flexors/extensors, insertion tendinopathies.
• Nervous: functional nerve constrictions/irritations (ulnar nerve, radial nerve, median nerve).
• Fascial/biomechanical: limited sliding tissue, incorrect shoulder/hand statics, poor technique.
• Mixed images: e.g. B. Tendinopathy with accompanying nerve irritation symptoms (double crush concept).

Causes and risk factors

• Repetitive movements: mouse/keyboard work, assembly, crafts, making music.
• Sports activities: racket sports, climbing, throwing/strength sports, CrossFit, rowing.
• Technical/ergonomics errors: unfavorable handle sizes, hard support edge, unfavorable wrist angles.
• Sudden increase in load without adaptation (e.g. training jump, DIY).
• Previous injuries, scars, swelling, bony growths (osteophytes).
• Systemic factors: diabetes, thyroid disorder, nicotine, certain medications.
• Proximal influences: neck/shoulder imbalance, scapular control, incorrect statics.

Typical symptoms

• Pain locally on the inner/outer elbow, often dependent on stress.
• Radiating into the forearm/hand, pain dependent on gripping or turning movements.
• Tingling, numbness or electrification (indication of nerve involvement).
• Loss of strength, unsteady grip, rapid fatigue.
• Morning stiffness, feeling of “rubbing” or “snapping” when moving.

The distribution of the abnormal sensations can provide clues: ulnar side (ring/little finger) speaks more for ulnar nerve, dorsal forearm/back of hand for radial nerve, thumb–middle finger more for median nerve. However, an exact assignment is made through examination.

Differential diagnoses at a glance

• Epicondylopathy (tennis/golfer's elbow) without nerve involvement.
• Carpal tunnel syndrome or proximal median nerve narrowing.
• Radial tunnel syndrome vs. lateral epicondylopathy.
• Sulcus ulnaris syndrome (ulnar narrowing at the elbow).
• Cervical radiculopathy, thoracic outlet problem.
• Osteoarthritis, loose joint bodies, plica/synovial folds.
• Inflammation, rarely infections or rheumatological causes.

Diagnostics: thorough and targeted

It is important to differentiate whether the tendon/muscle or a nerve or a combination is primarily affected. This determines the treatment priority.

Conservative treatment – ​​the standard approach

Most elbow strain and dysfunction problems can be treated without surgery. We combine stress control, training therapy, targeted physiotherapy and, if necessary, temporary medication support.

• Load management: temporary reduction of pain-causing activities, gradual reconstruction.
• Physiotherapy: eccentric-concentric tendon training, stretching, myofascial techniques, mobilization of the cervical spine/shoulder, coordination of the scapula.
• Nerve mobilization (nerve gliding): carefully measured gliding exercises for the ulnar nerve, radial nerve, median nerve - symptom-guided, not painful.
• Ergonomics & technology: Adjustment of workstation, tools, sports technique (grip strength, support, wrist angle).
• Aids: epicondylitis bandage, forearm cuff, if necessary night ulnar splint for flexion-related problems.
• Medications: short-term anti-inflammatory painkillers or topical NSAIDs; Benefits and risks are weighed individually.
• Cold/heat depending on tolerance, active break and micro-breaks in everyday life.

We usually plan a structured therapy trial over 6-12 weeks with clear interim goals. The increase in load occurs in small steps (e.g. +10–15% per week), depending on pain and function.

Regenerative processes – selective and enlightened

In the case of treatment-resistant tendinopathies or stubborn sliding disorders, additional procedures can be discussed. The evidence varies depending on the indication and is discussed transparently in advance.

• Ultrasound-targeted injections: e.g. B. peritendinous in tendinopathy, with careful indication. Cortisone can provide short-term pain relief; potential side effects and risk of recurrence are taken into account.
• Hydrodissection (ultrasound-targeted) to release adhesions around nerves: may be considered in individual cases; Data is still limited.
• PRP/ACP for chronic tendinopathies: mixed studies; possible if basic therapy has been exhausted.
• Shockwave: v. a. to be considered for tendinopathies; not for nerve compression.

Regenerative measures do not replace structured training and stress-adapted rehabilitation, but can be supplemented in individual cases.

Surgical options – only if there is a clear indication

Surgery is considered if persistent symptoms persist despite consistent conservative therapy or if objective nerve dysfunction (increasing weakness, sensory loss, conduction block) is evident. The specific procedure depends on the cause, e.g. B. Decompression of the ulnar nerve in the ulnar sulcus, radial tunnel decompression or removal of disturbing structures.

Before a surgical step, we provide detailed information about the benefits, risks and alternatives. In the case of specific nerve bottlenecks, we refer you to the corresponding detailed pages.

Self-help: everyday measures and exercises

• Micro-breaks: every 30-45 minutes of work on the mouse/keyboard, briefly loosen up, shake out your forearm.
• Ergonomics: Rest your forearms on a soft edge, keyboard flat, mouse close to your body, wrist neutral.
• Metered stretches: Forearm flexors/extensors, gentle 20-30 seconds 3 times a day, pain-free.
• Strengthening: gradual build-up with rubber band/dumbbell (light load), 3 times/week, pain max. 3/10.
• Nerve sliding: only with few symptoms and correctly instructed; Stop exercises if tingling/pain increases.
• Warmth before exertion, cold after higher exertion - depending on individual tolerance.

Course and prognosis

Many sufferers achieve noticeable improvement within weeks with consistent conservative treatment. In chronic cases, rehabilitation can take several months. What is crucial is adapted load control, technique optimization and sticking to the training program. Relapses are possible when stress peaks occur without preparation - prevention helps to avoid this.

Prevention: How to prevent it

• Increase training gradually (rule of thumb: 10-15% per week).
• Regular strength and coordination training for the forearm, shoulder girdle and torso.
• Have sports technique and grip sizes checked; Adjust racket stringing.
• Adjust the workplace ergonomically; Use soft support edges.
• Adequate recovery time, sleep and a balanced diet.
• Address risk factors: e.g. B. Nicotine reduction, blood sugar control in diabetes.

When should I seek medical advice?

• Sudden severe pain after trauma or snapping sensation.
• Increasing numbness, persistent tingling or weakness, dropping objects.
• Muscle regression (atrophy) in the hand/forearm.
• Redness, warmth, fever or severe pain at night.
• Complaints despite home measures > 2–4 weeks.

Typical sufferers

• Desk workers with high mouse/keyboard usage.
• Crafts, assembly, nursing professions – repeated gripping/rotating movements.
• Racket athletes, climbers, throwing and strength sports.
• Musicians (string, keyboard, wind instruments).
• Elderly with degeneration/tendinopathy; People with diabetes or thyroid disorders.
