Sagittal Deformity Treatment in Germany

Sagittal spinal deformity is a disruption of the natural spinal curves in the lateral (sagittal) plane. A healthy person's spine has physiological curves: cervical lordosis, thoracic kyphosis, lumbar lordosis and sacral kyphosis. Their harmonious combination allows maintaining the center of gravity of the head over the pelvis with minimal muscular effort. When sagittal balance is disrupted, the patient leans forward, experiences chronic pain and progressive decline in quality of life. German clinics employ precise diagnostic methods, surgical correction and innovative MIBRAR® therapy.

What is sagittal deformity

Sagittal balance is assessed by the position of the plumb line from the center of the C7 vertebral body relative to the posterior-superior corner of the sacrum (S1). This parameter is called SVA (Sagittal Vertical Axis). Normally SVA does not exceed 5 cm — the line passes through or slightly anterior to S1. With positive sagittal imbalance (SVA > 5 cm), the plumb line shifts forward, and the patient compensates by knee flexion, pelvic retroversion and back muscle tension.

Key sagittal balance parameters:

• PI (Pelvic Incidence) — anatomical pelvic parameter, does not change with age. Determines the "budget" of lumbar lordosis.
• LL (Lumbar Lordosis) — lumbar lordosis. Normally PI = LL ± 10°.
• TK (Thoracic Kyphosis) — thoracic kyphosis. Normally 20–45°.
• PT (Pelvic Tilt) — pelvic tilt. Compensatory indicator: when PT > 25° compensation reserves are exhausted.
• SVA — vertical distance from C7 to S1. SVA > 5 cm — significant imbalance.

Violation of the PI = LL formula is the main cause of sagittal imbalance and one of the leading causes of pain syndrome after spinal surgery.

Causes

1. Degenerative changes — disc degeneration and facet joint arthritis lead to loss of lumbar lordosis. Most common cause in elderly patients.
2. Compression fractures — osteoporotic vertebral fractures with wedge deformity increase thoracic kyphosis.
3. Iatrogenic imbalance — improper lordosis restoration during spinal fusion, insufficient correction in scoliosis. Common cause of FBSS.
4. Ankylosing spondylitis (Bechterew's disease) — progressive kyphosis with spinal ankylosis.
5. Scheuermann's disease — juvenile structural thoracic kyphosis.
6. Neuromuscular diseases — parkinsonism, myopathies, neurodegenerative processes.
7. Flat-back syndrome — loss of lumbar lordosis after spinal fusion with Harrington rods or improper fixation.

Symptoms

• Forward trunk lean — inability to stand upright without effort. Patient "collapses" by end of day.
• Chronic back pain — constant pain in lumbar and thoracic regions due to paravertebral muscle overload.
• Compensatory mechanisms — knee flexion, pelvic retroversion, neck hyperextension — secondary pain in knees, hips, neck.
• Rapid fatigue — inability to walk or stand for long periods.
• Balance impairment — fall risk, especially in elderly.
• Neurological symptoms — with concomitant spinal stenosis or foraminal stenosis: radicular pain, numbness, leg weakness.
• Daily activity limitation — difficulties with cooking, cleaning, communication (inability to look forward).

Diagnosis

1. Clinical examination — posture assessment in standing position, trunk inclination (C7-plumb), compensatory knee flexion, range of motion.
2. Full-length spine radiography (EOS / full-length X-ray) — key method! Standing image of entire spine from C2 to femoral heads. Measurement of SVA, PI, LL, TK, PT, SS (Sacral Slope).
3. MRI — disc assessment, neural structures, stenosis, tumor exclusion.
4. CT — surgical correction planning, vertebral bone structure assessment (bone quality for screws).
5. DEXA densitometry — mandatory before surgical correction! Osteoporosis increases construct loosening risk.
6. Functional X-rays — deformity rigidity assessment, correction potential.

Conservative treatment

Conservative therapy is effective for mild imbalance (SVA < 5 cm) and as support before and after surgical correction:

• Physical therapy — back extensor strengthening, core stabilization, extension exercises. Schroth method-based programs for kyphotic deformity.
• Drug therapy — NSAIDs, analgesics for pain control. Osteoporosis treatment (bisphosphonates, denosumab, teriparatide) to prevent new fractures.
• Bracing — thoracolumbar brace for compression fractures, temporary support.
• Epidural and facet blocks — for concomitant radicular syndrome.

MIBRAR® therapy

Sagittal spinal deformity is included in the list of indications for MIBRAR® technology (individual assessment). Prof. Babayan's method aims to regenerate degeneratively altered spinal structures.

MIBRAR® principle: "Kein Schnitt, nur ein Stich!" — no incision, only a puncture. Autologous regenerative concentrate (ARK), containing growth factors, anti-inflammatory factors and mesenchymal stem cells, is transplanted directly into the affected area under Sono Control Arm™ guidance (0.1 mm precision).

MIBRAR® for sagittal deformity:

• Intervertebral disc regeneration — restoring disc height increases lumbar lordosis.
• Facet joint regeneration — cartilage restoration reduces pain syndrome and improves segment mobility.
• Anti-inflammatory effect — reduction of swelling and pain without cortisone. Stem cells migrate to where they are "most needed" (from Prof. Babayan's book).
• Surgical correction support — MIBRAR® can be used as adjunct to spinal fusion to accelerate bone healing.

Outpatient procedure, without anesthesia, without hospitalization. Exclusively autologous material is used — no side effects associated with synthetic drugs. Over 10 years — more than 11,000 international cases without significant complications.

Surgical treatment

Surgical correction is indicated for SVA > 5 cm with progression, conservative therapy failure and significant quality of life limitation. Goal — restore PI = LL ± 10° formula and SVA < 5 cm.

Surgical correction methods:

1. SPO (Smith-Petersen Osteotomy) — wedge resection of posterior vertebral elements. Correction 10–15° per level. Indicated for mobile deformities.
2. PSO (Pedicle Subtraction Osteotomy) — wedge resection through pedicle and vertebral body. Correction 25–35° per level. Gold standard for rigid deformity.
3. VCR (Vertebral Column Resection) — complete vertebral resection. Maximum correction (up to 60°). Indicated for severe rigid deformities.
4. Spinal fusion — stabilization with transpedicular screws and rods. Usually long fusion from upper thoracic to sacrum/pelvis.
5. ACR (Anterior Column Realignment) — lateral approach, correction through disc. Less traumatic alternative to PSO.

All surgeries performed with neuromonitoring (SSEP, MEP), robotic navigation and intraoperative balance control (radiography).
