The Spastic Upper Extremity: General Principles in the Surgical Management of the Spastic Upper Extremity

Peter Rhee, DO, MSc

[email protected]

Upper Motor Neuron Syndrome • Disruption of UMN inhibitory pathways • Impaired regulation or loss of voluntary movement • Causes

• Brain Injury • Cerebrovascular accident (CVA) • Traumatic brain injury (TBI) • Anoxic brain injury (ABI)

• Spinal cord injury (SCI) Upper Motor Neuron Syndrome: Signs and Symptoms

• Immediate → Flaccidity • Days to weeks → Increasing motor tone

• Unmasking of primitive reflexes • Spinal reflex hyperactivity

Spinal reflex hyperactivity • Exaggerated muscle activation in response to:

• Quick stretch → spasticity • Slow stretch → rigidity

• Can results in spastic co-activation → dyssynergy Surgical Management Options for Spastic Deformities

• Functional = Volitional muscle control • Non-Functional = No volitional muscle control

Case

• 6 year-old female with hemiplegic CP. She has undergone botoxinjection and therapy for years. Not seeing improvement any longer. Primarily difficulty gripping

Faculty opinion

• Approach?

Washington University Orthopedics | | St. Louis Children’s Hospital | Shriner’s Hospital for Children-St. Louis

Flexed wrist deformity

• Tendon fractional lengthening• +/- ECU centralization

• Tendon transfer• FCU transfer to wrist extensor

• Partial neurectomy of FCU innervation

• * Wrist arthrodesis

Washington University Orthopedics | | St. Louis Children’s Hospital | Shriner’s Hospital for Children-St. Louis

Tendon transfer considerations

• Augments weak extensors•Don’t forget the finger flexors•Dynamic vs static transfer• Role of EMG

Washington University Orthopedics | | St. Louis Children’s Hospital | Shriner’s Hospital for Children-St. Louis

Technical considerations

• FCU origin is long = long incision for harvest• Ensure no fascial entrapment around ulna• Transfer through interosseous space• If worried about too much supination

• Transfer to ECRB or ECRL• Wrist in neutral

Patterson et al. JHS 2010

Post-operative Rehabilitation

• Cast for 5 weeks• Wrist brace for 4 weeks with OT for gentle active motion• Young patients full time brace wear

• Brace nighttime for 3-4 weeks
