S24.141

Clinical Causes: Traumatic injury such as spinal fractures, dislocations, or stab wounds affecting the T1 level Spinal tumors or growths impacting the spinal cord at T1 Multiple sclerosis (rare at this level but possible) Infections leading to spinal cord inflammation or abscesses Disc herniation pressing on the spinal cord or nerves Vascular issues such as spinal cord infarction or bleeding Iatrogenic causes such as complications from spinal surgery

Key Symptoms: Loss of motor function (weakness or paralysis) on the same side as the injury Loss of pain and temperature sensation on the opposite side of the injury Preservation of some sensory modalities depending on the extent of damage Altered reflexes and changes in muscle tone Possible bowel or bladder dysfunction Sensory deficits such as numbness or tingling in affected areas Muscle stiffness or spasticity below the level of injury

Diagnosis Path: Neurological examination to assess motor strength, sensation, and reflexes Magnetic Resonance Imaging (MRI) to visualize the extent and location of spinal cord damage Computed Tomography (CT) scans if fractures or bony injuries are suspected Electrophysiological studies like somatosensory evoked potentials (SSEPs) to evaluate nerve function Additional tests to rule out infection, tumor, or other underlying causes

Treatment Protocols: Acute management with corticosteroids to reduce inflammation and swelling Surgical intervention if there is spinal compression, fracture fixation, or tumor removal Pain management with medications tailored to individual needs Physical and occupational therapy to promote movement, strength, and independence Assistive devices and adaptive strategies for mobility and daily activities Monitoring and managing autonomic functions like bladder and bowel control Long-term rehabilitation programs to optimize recovery and quality of life
