Case ReportsFemoral nerve injury complicating continuous psoas compartment block.
The objective of this case report is to describe a femoral nerve injury after a psoas compartment block (PCB) and to discuss the probable mechanisms of injury and neuron regeneration. To date, this is the first report of severe femoral nerve injury after PCB. ⋯ Severe nerve injuries after regional anesthesia techniques remain infrequent and probably unreported. Our case report suggests that severe femoral nerve injury should be added to the list of reported complications during PCB. This case report is also encouraging because it shows the possibility of a good recovery after such injury.

Case ReportsPiriformis syndrome in a patient after cesarean section under spinal anesthesia.
The diagnosis, pathogenesis, and treatment of piriformis syndrome as a cause of persistent buttock and hip pain after spinal anesthesia are presented in this case report. ⋯ Back pain with radiation into the buttocks after spinal anesthesia is frequently attributed to the spinal procedure itself. However, prolonged sitting and weight bearing in the upright position after cesarean delivery can cause sciatic nerve compression at the sacroiliac joint with concomitant irritation, inflammation, and spasm of the piriformis muscle. Piriformis syndrome is frequently underdiagnosed in the obstetric population. Because the diagnosis of piriformis syndrome is based mainly on clinical signs and symptoms, the clinician must have a high index of suspicion.
