★ World First: FSPR for Paralyzed Hand — Dr. Sun Chenyan (2016)

FSPR — Functional Selective Posterior Rhizotomy

A precision neurosurgical procedure for reducing spasticity in cerebral palsy, hemiplegia, and paraplegia. Pioneered and continuously refined by Dr. Sun Chenyan at Eber Medical Group — including the first-in-world FSPR for a paralyzed hand.

What is FSPR?

FSPR — Functional Selective Posterior Rhizotomy — is a neurosurgical procedure that permanently reduces limb spasticity by selectively sectioning the overactive dorsal nerve rootlets in the spinal cord. Unlike drug treatments (e.g., baclofen, botulinum toxin), FSPR provides permanent spasticity reduction without ongoing medication.

The procedure was first adapted to clinical practice in China by Dr. Sun Chenyan at Eber Medical Group. In 2016, Dr. Sun performed the first-in-world FSPR for a paralyzed hand — a landmark extension of the technique to upper-limb spasticity. After surgery, patients who previously had a non-functional, contracted hand regained the ability to perform fine motor tasks: cutting vegetables, tying shoelaces, and brewing tea.

Indications for FSPR

  • Spastic cerebral palsy (CP) — lower and upper limb spasticity; from 6 months of age
  • Hemiplegia with limb spasticity (post-stroke, trauma, CP)
  • Paraplegia with lower limb spasticity (spinal cord injury, spina bifida)
  • Paralyzed hand with spasticity — Eber's unique indication (world first)
  • Equinus foot, scissor gait, clenched fist deformity

FSPR Procedure: Technical Excellence

At Eber Medical Group, FSPR is performed with a focus on bone-preserving surgery. Unlike traditional Selective Dorsal Rhizotomy (SDR) that often requires extensive bone removal, our technique utilizes Hemi-laminectomy or even procedures without bone resection.

  1. Bone-Preserving Access: Minimal incision and limited bone window to access the spinal canal. This preserves the structural integrity and stability of the growing child's spine.
  2. Intraoperative Neurophysiological Monitoring (IONM): Continuous 50Hz stimulation using Carl Zeiss surgical microscopes to identify pathological rootlets.
  3. Precision Sectioning: Only the overactive Ia-fibers are sectioned, effectively "cutting the noise" without losing sensation.
  4. Minimal Blood Loss: Advanced hemostatic technologies ensure the procedure is virtually bloodless.

Rehabilitation After FSPR

Rehabilitation is integral to FSPR outcomes — surgery removes the spasticity barrier, but neuroplasticity and function are rebuilt through structured therapy:

Phase Duration Focus
Acute (Inpatient) Weeks 1–4 Wound care, early passive/active ROM, sensory re-education, bladder function
Sub-acute Rehabilitation Months 1–3 Muscle strengthening, gait training, occupational therapy, TMS, acupuncture
Active Rehabilitation Months 3–6 Functional tasks (writing, walking, ADL), robotic therapy, sports, independence
Maintenance Ongoing Home exercise program, outpatient TCM, periodic reassessment

Outcomes: What Patients Achieve After FSPR

  • Significant, permanent reduction in limb spasticity (MAS score improvement)
  • Improved gait — children who previously walked with scissors gait walk normally
  • Hand function restoration — fine motor tasks previously impossible become achievable
  • Reduced need for oral spasticity medications (baclofen, tizanidine)
  • Improved quality of life and family caregiver burden

FSPR — Frequently Asked Questions

What conditions is FSPR used for?
FSPR — Functional Selective Posterior Rhizotomy — is used for spastic cerebral palsy (CP), hemiplegia, paraplegia, and spasticity from spinal cord injury. It is particularly effective for lower limb spasticity (scissor gait, equinus foot) and, uniquely at Eber, for upper limb/hand spasticity — Dr. Sun Chenyan performed the first-in-world FSPR for a paralyzed hand in 2016.
How does FSPR differ from conventional SDR (Selective Dorsal Rhizotomy)?
FSPR (Functional Selective Posterior Rhizotomy) is a more refined, function-preserving version of SDR. It targets only rootlets causing pathological spasticity while preserving sensory function — verified by intraoperative neurophysiological monitoring (IONM). Eber's technique, developed by Dr. Sun Chenyan, also extends the indication to upper-limb spasticity (first-in-world for paralyzed hand, 2016).
What results can patients expect after FSPR?
For lower limbs: significant reduction of spasticity, improved gait pattern, better walking speed and endurance. For upper limbs/hand (Eber's innovation): patients regain fine motor function — cutting vegetables, tying shoelaces, writing, brewing tea. Combined with 3–6 months of rehabilitation, most patients achieve functional independence milestones.
What is the recovery timeline after FSPR?
Week 1–4: Inpatient rehabilitation, wound care, early physiotherapy. Months 1–3: Intensive outpatient/inpatient rehab, muscle strengthening, gait training, occupational therapy. Months 3–6: Progressive functional rehabilitation; most improvement achieved. TCM (acupuncture, tuina) is integrated throughout the rehabilitation phase.
Is FSPR safe for young children?
Yes. FSPR is performed at Eber Medical Group in children from 6 months of age under general anesthesia with continuous intraoperative monitoring. The safety profile is well-established; the most significant risks are temporary sensory changes and urinary retention, both managed proactively in our ICU-equipped facility.
