Final answer:
The patient's symptoms suggest compartment syndrome, likely due to increased pressure in the leg compartments after surgery for an acute embolus, requiring prompt diagnosis and treatment.
Step-by-step explanation:
The clinical presentation of a patient who has good perfusion to the foot and toes but cannot dorsiflex the foot, along with tenderness in the calf following surgery for an acute embolus, suggests the possibility of compartment syndrome. This condition occurs when there is increased pressure within the compartments of the leg, usually due to swelling or bleeding, which can compromise circulation and nerve function. Since the patient has had an acute embolus and surgery, the risk of developing compartment syndrome is increased. The inability to dorsiflex the foot, known as foot drop, and calf tenderness are typical signs. It is imperative to diagnose this condition promptly as it can lead to permanent damage if not treated quickly.
