Write answer in between .Q:Seven hours after undergoing left hip arthroplasty for chronic hip pain, a 67-year-old woman reports a prickling sensation in her left anteromedial thigh and lower leg. Neurologic examination shows left leg strength 35 on hip flexion and 25 on knee extension. Patellar reflex is decreased on the left. Sensation to pinprick and light touch are decreased on the anteromedial left thigh as well as medial lower leg. Which of the following is the most likely underlying cause of this patients symptoms?? A: Sural nerve injury, B: Femoral nerve injury, C: Fibular nerve injury, D: S1 radiculopathy, E: L5 radiculopathyn,  <response>: This is a patient who underwent left hip arthroplasty and is now experiencing neurological deficits in the left lower extremity. The key findings are decreased strength in hip flexion and knee extension, decreased patellar reflex, and decreased sensation in the anteromedial thigh and medial lower leg. This localizes the lesion to the femoral nerve, which innervates the quadriceps knee extension and saphenous nerve territory anteromedial thigh and medial lower leg. Sural, fibular, and L5 nerves can be ruled out based on the distribution of symptoms. S1 radiculopathy would cause posterior thigh and lateral leg deficits rather than anteromedial thigh and medial lower leg. Therefore, the most likely cause is a femoral nerve injury during the hip arthroplasty.B: Femoral nerve injury
