CHIEF COMPLAINTS:Patient currently complains of pain and numbness in the right elbow for several months.
CLINICAL DIAGNOSIS. Right Cubital Tunnel Syndrome.
MOTOR AND SENSORY STUDIES:
Motor nerve conduction studies stimulating bilateral median and the left ulnar nerves revealed normal distal latencies, normal amplitudes and normal nerve conduction velocities.Sensory studies testing bilateral median , ulnar and radial nerves revealed normal distal latencies, normal amplitudes and normal nerve conduction. velocities. The right ulnar nerve showed a slow NCV across elbow. The elbow was flexed at a 90 degree angle. Temperature was within range.
Bilateral Median F-wave studies with recording electrodes at the APB muscle displayed normal latencies and normal amplitudes.Bilateral ulnar F-wave studies with recording electrodes at the ADQ muscle displayed normal latencies and normal amplitudes.There is no significant side to side differences.
Electromyography examination was performed with a monopolar disposable needle on the muscles indicated in the attached table. Study revealed no signs of electrical instability.No evidence of dennervation potentials at rest affecting predominantly the FDI and FCU muscles.Recruitment was within normal limits.
Electrodiagnostic study revealed evidence of a moderate right Cubital Tunnel Syndrome across the elbow.
