Abstract
Recording of intramuscular pressure by using the injection technique in different ways has been evaluated in 12 healthy subjects and 12 patients with medial tibial syndrome. Pressure recording with an injection needle was compared to the recerding by a Teflon catheter with multiple side holes at its tip. Following an injection of 0.07 ml, the intramuscular pressure was significantly higher when it was recorded with the injection needle. Pressure recorded with an injection needle by the “meniscus method” was found to be significantly closer to the preinjection pressure compared to the injection technique described by Whitesides et al. (13). Pressure readings by the “meniscus method” after injection, and by a catheter or needle with multiple side holes, decrease the drawbacks of the injection technique.
