Neuroregeneration

What does neuroregeneration mean in orthopedics?

Peripheral nerves consist of nerve fibers (axons) that are surrounded by supportive connective tissue and a protective myelin layer. When they are irritated or injured, the body attempts to regulate inflammation, improve blood flow and repair damaged structures. The aim of orthopedic neuroregeneration is to relieve and specifically promote these natural processes - especially through relief, exercise therapy, metabolic optimization and carefully selected, evidence-conscious additional procedures.

Briefly explained: nerve anatomy and relevance

• Peripheral nerves: motor, sensory and autonomic fibers outside the brain and spinal cord
• Protective layers: endo-, peri- and epineurium; important for lubrication and nutrition of the nerve
• Regeneration: peripheral nerves can partially recover functionally under favorable conditions; the speed is limited
• Central vs. peripheral: Central nerves (brain/spinal cord) regenerate to a much lesser extent; in orthopedics the focus is peripheral

When does neuroregeneration make sense?

• Nerve compression syndromes: e.g. B. Carpal tunnel syndrome, ulnar sulcus syndrome, tarsal tunnel syndrome, Morton's neuralgia
• Spinal nerve root irritation (radiculopathy): e.g. B. in the case of a herniated disc or foraminal stenosis
• Post-traumatic or postoperative nerve irritation: scarring, hematomas, neuromas
• Sports and overuse injuries: repeated microtraumas, myofascial tightness
• Metabolic factors: diabetic polyneuropathy and other metabolic disorders - orthopedically relevant in the management of symptoms; causal treatment interdisciplinary

Which measures are suitable in each individual case depends on the cause, duration and severity of the symptoms as well as comorbidities.

Typical symptoms and warning signs

• Tingling, burning, electrifying pain, numbness
• Loss of strength, clumsiness, muscle weakness
• Sensitivity to cold or heat, allodynia (pain to touch)
• Night pain, stress-related aggravation

Warning signs that require immediate medical attention:

• Acute, progressive loss of strength or paralysis
• Difficulty defecating/urinating, numbness in the riding breeches area
• Fever, severe inflammation, rapidly increasing swelling
• Accident event with possible nerve or vascular injury

Diagnostics: understand the cause, plan therapy in a targeted manner

• Medical history: course of pain, triggers, nighttime complaints, previous operations, previous illnesses
• Clinical examination: neurostatus, strength, sensitivity and reflex testing, provocation tests (e.g. Tinel sign, Phalen test, Slump/ULNT)
• High-resolution ultrasound: visualization of nerve caliber, gliding ability, constrictions, scars
• Nerve conduction velocity/EMG (cooperation partner): objectification of damage pattern and severity
• Imaging (MRI/CT): if an intervertebral disc, spinal canal stenosis or masses are suspected
• Laboratory: if metabolic or inflammatory causes are suspected (e.g. diabetes, vitamin deficiency)

Conservative basic therapy – the foundation of neuroregeneration

Conservative treatment precedes any specialized measure. The aim is to reduce mechanical irritation, provide the nerve with a metabolically beneficial supply and calm pain processing.

• Relief and ergonomics: workplace adjustment, night positioning splints (e.g. wrist), padding/changing shoes
• Physiotherapy: neurodynamic mobilization, sliding exercises, posture training, myofascial techniques
• Dosed activity: gradual increase in load instead of resting; Targeted strengthening of the surrounding muscles
• Drug pain therapy as needed: evidence-based step-by-step schemes, cautious use, regular reevaluation
• Local measures: Cooling/heat depending on tolerance, tape/orthosis in individual cases
• Psychoeducation: Understanding nerve healing and realistic time progression reduces stress and pain focus

Metabolism, sleep and micronutrients

A well-regulated metabolism is essential for nerves. This includes nutrition, sleep and, if necessary, micronutrients.

• Blood sugar management for diabetes in coordination with your family doctor/diabetologist
• Low-inflammatory diet: sufficient protein, omega-3 fatty acids, vegetables/fruit; Reduce alcohol and nicotine
• Sleep hygiene: consistent sleep times, optimize sleep environment; Lack of sleep increases sensitivity to pain
• Micronutrients: B vitamins, vitamin D or magnesium only if clearly indicated; no blanket high-dose recommendations

Neuromodulative and regenerative procedures – when do they complement?

Additional procedures can be useful if conservative measures alone do not help sufficiently or if a targeted, local stimulus should support regeneration. We examine the benefits, risks and evidence individually. Some procedures are off-label and are currently being further scientifically investigated.

PRP neuromodulation

During PRP neuromodulation, the body's own platelet-rich plasma (PRP) is introduced into the area surrounding irritated nerve structures under ultrasound control. The aim is to modulate local inflammation and improve the tissue environment.

• Indications: localized nerve irritations, tendinopathies with nerve involvement, selected constriction syndromes
• Process: blood collection, preparation, ultrasound-targeted injection; mostly serial treatment
• Evidence: growing number of studies for selected indications; Quality of evidence heterogeneous
• Risks: temporary increase in pain, hematoma, infection (rare)

Axomera (percutaneous bioelectric therapy)

Axomera delivers short, weak electrical stimuli intended to modulate local neuro- and tissue regulation. It is applied specifically along anatomical pathways.

• Possible areas of application: nerve irritations, myofascial pain syndromes
• Evidence: clinical experience reports and initial studies; further research is ongoing
• Tolerability: generally good; occasionally tiredness, temporary change in symptoms

Shock wave therapy (ESWT) perineural

Focused or radial shock waves are applied in low doses to the area around the nerve or to adjacent tissue. Hypothesis: Microcirculation and tissue repair processes are stimulated.

• Application: e.g. B. Morton's neuralgia, myofascial tightness
• Evidence: heterogeneous; positive signals in some indications, overall further research is needed
• Side effects: redness, tenderness, rarely hematoma

EMTT and laser regeneration (photobiomodulation)

Magnetic-mechanical stimuli (EMTT) and certain laser protocols aim to have a biostimulative effect. In the case of nerve irritation, they are sometimes used as a supplement.

• Goal: Activation of metabolism, promotion of blood circulation, modulation of peripheral nociception
• Evidence: inconsistent; Procedures can be part of a multimodal plan
• Tolerability: mostly good; local irritation reactions possible

Transcranial pulse stimulation (TPS)

TPS is a non-invasive brain stimulation with ultrasound pulses and is primarily investigated for neurological/psychiatric indications. Orthopedically, TPS can only be relevant in individual cases with central pain modulation.

Important: TPS is not a standard procedure in orthopedic pain therapy. Application takes place - if at all - after strict indications and interdisciplinary coordination.

Stem cell therapy – currently not standard

Stem cell-based procedures for peripheral nerves are predominantly in the experimental area. They are not part of routine care in orthopedics. If offered in studies, we provide transparent information about the benefits, risks and alternatives.

Therapy step plan: structured and individual

Security, risks and limits

Each measure is checked individually for side effects. Conservative therapy is usually well tolerated. Local reactions are possible with injections and technical procedures; Infections, bleeding or nerve irritation rarely occur. Guaranteed improvement cannot be promised; The aim is to provide the best possible, evidence-based support for natural healing.

Healing time and prognosis

Nerves slowly recover. Depending on the cause and extent of the damage, improvements are possible within weeks to months; In the case of severe lesions, the course can be significantly longer. Decisive factors are relief of the cause, consistent therapy and comorbidities.

Costs and reimbursement

Many diagnostic and conservative measures are covered by health insurance companies. Some neuromodulative/regenerative procedures are individual health services (IGeL) or can be billed to private physicians according to GOÄ. Before you start you will receive a cost estimate; We support you with questions about reimbursement.
