Case ReportsAdductor canal block can result in motor block of the quadriceps muscle.
The block of nerves in the adductor canal is considered to cause a sensory block without a motor component. In this report, we describe a case of significant quadriceps muscle weakness after an adductor canal block (ACB). ⋯ Several studies have reported that ACB involves no motor blockade. However, our case report illustrates that the ACB can result in clinically significant quadriceps muscle paralysis. This report suggests that patients should be monitored vigilantly for this occurrence to decrease the risk of falls.

Case ReportsPneumothorax After Ultrasound-Guided Supraclavicular Block: Presenting Features, Risk, and Related Training.
Presenting features and estimate of risk of pneumothorax after ultrasound-guided supraclavicular block are discussed, along with related training strategies. ⋯ We estimate the risk of pneumothorax to be 0.4 per 1000 after ultrasound-guided supraclavicular block. We recommend specific training strategies for needle visualization for this technique to reduce the risk of pneumothorax.
