Diagnostics: Physical Exam – RH fetlock laceration, all other findings within normal limits.
Radiographs and Ultrasound – Within normal limits.
Arthrocentesis (Joint Tap) – a needle was placed in the RH fetlock joint opposite the laceration and 30 ml of sterile saline was then used to pressurize the joint at which time synovial fluid and saline began to leak from the laceration site. The laceration was determined to communicate with the RH fetlock joint.
Sterile fluid being infused with the arthroscope into the joint and expelled from the laceration site. Note how visible the laceration is once the hair is clipped.
