Introduction. A 58-year-old woman with debility from end-stage liver disease visited the clinic reporting weakness of her right upper extremity for the past day.
Patient history. The patient had fallen from her bed and remained lying on the floor for several hours until help arrived. Her right arm was compressed under her body the entire time, and she said she was unable to extend her right wrist. She denied numbness and tingling in her right hand and had no pain.
Physical examination. On physical examination, she could not fully extend her right wrist (Figure), but sensation was intact throughout. Her right-hand grip strength was normal. The intrinsic hand muscles of the lumbricals and interosseous muscles were intact. She had normal distal pulses and capillary refill. Results from a spurling test was negative. The rest of her nervous system examination was normal, including normal gait, vision, and speech, and she was negative for the Babinski sign.
Figure. Photo shows the patient demonstrating right wrist weakness when asked to extend both hands.
Based on the patient's history and physical examination, which one of the following is the most likely diagnosis?
A. Carpal tunnel syndrome
B. Cerebrovascular accident
C. Radial nerve compression
D. Cubital tunnel syndrome
E. Cervical radiculopathy
