Core Surgical Specializations
1. Brachial Plexus Injury Repair (臂丛神经损伤修复)
Dr. Dong specializes in surgical treatment of brachial plexus injuries, among the most devastating peripheral nerve injuries causing complete or partial arm paralysis.
Understanding Brachial Plexus Injuries:
The brachial plexus is a complex network of nerves (C5-T1) originating from the neck that controls all arm and hand movement and sensation. Injury to this network can result in complete arm paralysis, loss of sensation, and severe functional disability.
Common Causes:
- Motorcycle Accidents: High-energy traction injuries, most common in adults
- Motor Vehicle Collisions: High-speed impacts
- Birth Injuries: Shoulder dystocia during delivery (Erb's palsy)
- Sports Injuries: Contact sports, skiing accidents
- Falls: Landing on shoulder with arm extended
- Penetrating Trauma: Gunshot or stab wounds
Types of Brachial Plexus Injuries:
- Upper Plexus (C5-C6): Erb's palsy affecting shoulder and elbow
- Lower Plexus (C8-T1): Klumpke's palsy affecting hand
- Total Plexus (C5-T1): Complete arm paralysis
- Preganglionic Avulsion: Nerve roots torn from spinal cord (worst prognosis)
- Postganglionic Rupture: Nerve torn distal to ganglion (better prognosis)
Comprehensive Evaluation:
- Detailed Clinical Examination: Motor and sensory testing of all muscle groups
- Electrodiagnostic Studies: EMG and nerve conduction studies
- MRI Imaging: Visualizing nerve roots and plexus
- CT Myelography: Detecting nerve root avulsions
- Surgical Exploration: Direct visualization to assess injury severity
Surgical Reconstruction Strategies:
Nerve Repair and Grafting:
- Direct Repair: Suturing ruptured nerves when possible
- Nerve Grafting: Using sural nerve cables to bridge gaps
- Vascularized Nerve Grafts: For long defects requiring blood supply
Nerve Transfers (Dr. Dong's Expertise):
- For Elbow Flexion: Oberlin transfer (ulnar fascicles to biceps), median nerve to brachialis
- For Shoulder Function: Spinal accessory to suprascapular nerve, triceps branches to axillary nerve
- For Hand Function: Supinator branch to posterior interosseous nerve, brachialis to anterior interosseous nerve
- For Finger Flexion: ECRB to FDP, contralateral C7 transfer
- For Wrist Extension: Pronator teres to ECRB
Free Functional Muscle Transfer:
- Gracilis Muscle Transfer: For elbow flexion or finger flexion
- Double Free Muscle Transfer: Restoring both elbow and hand function
- Neurotized Muscle Transfer: Combining nerve transfer with muscle transfer
Tendon Transfers:
- Rerouting functioning muscles to restore lost movements
- Secondary procedures after nerve regeneration
Timing of Surgery:
- Early Exploration (3-6 months): For complete paralysis or no recovery signs
- Nerve Transfers (3-12 months): Optimal window for best results
- Secondary Procedures (12-24 months): Tendon transfers, free muscle transfers
Expected Outcomes:
- Elbow flexion recovery: 70-90% with nerve transfers
- Shoulder function: 60-80% improvement
- Hand function: Variable, depends on injury severity
- Sensation: Partial recovery in many cases
2. Hand Function Reconstruction After Spinal Cord Injury (脊髓损伤后手功能重建)
Dr. Dong has pioneering expertise in restoring hand function to patients with cervical spinal cord injuries (tetraplegia/quadriplegia), a field offering hope where little existed before.
Understanding Tetraplegia:
Cervical spinal cord injury results in paralysis of arms and legs. The level of injury determines which muscles remain functional. Even restoring limited hand function can dramatically improve independence and quality of life.
Classification by Injury Level:
- C5 Level: Shoulder and elbow flexion present, no wrist or hand function
- C6 Level: Wrist extension present, no finger or thumb function
- C7 Level: Some finger extension, limited hand function
- C8 Level: Better hand function but weak grip
Goals of Hand Reconstruction:
- Grasp Function: Ability to hold objects
- Pinch Function: Thumb-to-finger pinch for fine manipulation
- Release Function: Ability to let go of objects
- Elbow Extension: Reaching and positioning hand
- Improved Independence: Self-feeding, writing, using phone, personal care
Surgical Techniques:
Tendon Transfers (Primary Approach):
Rerouting functioning muscles above injury level to restore hand function:
-
For C5 Patients:
- Deltoid to triceps (elbow extension)
- Biceps to triceps (elbow extension)
- Brachioradialis to ECRB (wrist extension)
-
For C6 Patients:
- Brachioradialis to FPL (thumb flexion/pinch)
- ECRL to FDP (finger flexion/grasp)
- Pronator teres to FPL (alternative for pinch)
-
For C7 Patients:
- BR to FPL and ECRL to FDP (key pinch and grasp)
- Zancolli lasso procedure (intrinsic function)
Nerve Transfers (Emerging Technique):
- Transferring nerves from above injury level to paralyzed muscles below
- Supinator to PIN for finger extension
- Brachialis to AIN for thumb and finger flexion
- Earlier intervention possible compared to tendon transfers
Functional Electrical Stimulation (FES):
- Implanted electrodes stimulating paralyzed muscles
- Neuroprosthetic systems for grasp and release
- Combined with tendon transfers for optimal function
Arthrodesis (Joint Fusion):
- Wrist fusion for stable platform
- Thumb CMC fusion for stable pinch
- Finger joint fusions for positioning
Surgical Planning:
- Patient Selection: Motivated patients with stable injury (>1 year post-injury)
- Muscle Strength Assessment: Identifying donor muscles (must be grade 4+ strength)
- Goal Setting: Realistic expectations based on available donors
- Staged Procedures: Multiple surgeries over 1-2 years
- Intensive Rehabilitation: Critical for success, 6-12 months per procedure
Outcomes:
- 80-90% of patients achieve functional grasp and pinch
- Significant improvement in independence and quality of life
- Ability to self-feed, use phone, write, perform personal care
- Reduced dependence on caregivers
- Improved employment opportunities
3. Nerve Compression Disorders (神经卡压疾病)
Dr. Dong treats the full spectrum of peripheral nerve compression syndromes affecting upper and lower extremities.
Upper Extremity Nerve Compressions:
Carpal Tunnel Syndrome:
- Symptoms: Numbness/tingling in thumb, index, middle fingers; hand weakness; night pain
- Diagnosis: Clinical examination, nerve conduction studies
- Treatment: Endoscopic or open carpal tunnel release
- Outcomes: 90-95% excellent relief of symptoms
Cubital Tunnel Syndrome:
- Symptoms: Numbness in ring and small fingers, hand weakness, elbow pain
- Diagnosis: Tinel's sign at elbow, nerve conduction studies
- Treatment: Ulnar nerve decompression, transposition if needed
- Outcomes: 70-90% good to excellent results
Radial Tunnel Syndrome:
- Symptoms: Forearm pain, weakness with gripping
- Diagnosis: Clinical examination, diagnostic injection
- Treatment: Radial tunnel release, supinator decompression
Thoracic Outlet Syndrome:
- Symptoms: Arm pain, numbness, weakness; vascular symptoms
- Diagnosis: Provocative tests, imaging, nerve studies
- Treatment: First rib resection, scalene muscle release
Pronator Syndrome:
- Symptoms: Median nerve compression in forearm
- Treatment: Pronator teres release
Lower Extremity Nerve Compressions:
- Tarsal Tunnel Syndrome: Posterior tibial nerve compression at ankle
- Peroneal Nerve Compression: At fibular head causing foot drop
- Meralgia Paresthetica: Lateral femoral cutaneous nerve compression
- Piriformis Syndrome: Sciatic nerve compression by piriformis muscle
Surgical Approaches:
- Endoscopic Release: Minimally invasive for carpal tunnel
- Open Decompression: Direct visualization and complete release
- Nerve Transposition: Moving nerve to less compressed location
- Neurolysis: Freeing nerve from scar tissue
- Epineurotomy: Releasing tight nerve sheath
Outcomes:
- Earlier surgery yields better results
- Sensory symptoms improve faster than motor weakness
- Most patients experience significant relief
- Severe, long-standing compression may have incomplete recovery
Comprehensive Rehabilitation
Dr. Dong emphasizes that surgery is only part of treatment - intensive rehabilitation is critical for optimal outcomes:
Pre-Operative Therapy:
- Maintaining joint range of motion
- Preventing contractures
- Strengthening available muscles
- Learning adaptive techniques
Post-Operative Rehabilitation:
- Early Phase (0-6 weeks): Wound healing, gentle range of motion
- Strengthening Phase (6-12 weeks): Progressive resistance exercises
- Functional Training (3-12 months): Task-specific practice, motor relearning
- Long-Term Optimization: Continued therapy as nerve regenerates

Frequently Asked Questions
Can hand function be restored after spinal cord injury?
Yes, tendon transfers and nerve transfers can restore grasp, pinch, and release function in many tetraplegic patients, dramatically improving independence. Success depends on injury level and available donor muscles.
How long does recovery take after brachial plexus surgery?
Nerve regeneration takes 12-24 months. Functional improvement is gradual. Multiple staged procedures over 1-2 years may be needed for optimal results.
Should I have carpal tunnel surgery?
Surgery is recommended when conservative treatment (splinting, injections) fails, or when there's muscle wasting or severe nerve damage on testing. Earlier surgery prevents permanent nerve damage.
What is success rate for nerve transfers?
Nerve transfers for elbow flexion achieve useful function in 70-90% of patients. Hand function restoration is more variable. Earlier surgery yields better results.
Am I too old for brachial plexus surgery?
Age is less important than time since injury and overall health. Nerve transfers can work in older patients. Dr. Dong evaluates each case individually.
How long should I stay in Shanghai?
Plan for 2-3 weeks: evaluation (2-3 days), surgery and hospital stay (3-7 days), initial therapy and follow-up (1-2 weeks) before traveling home.
