How To Do Metatarsophalangeal Joint Arthrocentesis
Warnings and Common Errors for MTP Joint Arthrocentesis
Carefully ensure optimal positioning before joint puncture. Allow adequate time for local anesthesia to take effect before proceeding. To avoid damaging the synovium and articular cartilage, do not advance the needle against resistance and do not move the needle once it has begun draining synovial fluid. If the needle tip must be relocated, first withdraw it almost to the skin surface andthenredirect; do not try to change the angle of insertion while a needle is embedded in tissue.
