ABSTRACT:
A device for controlling the injection of a cement into a cavity is provided which is particularly useful in the practice of total hip arthroplasty. A canister holds a standard cement syringe and supports a retracting assembly which withdraws a nozzle of the syringe into the canister. The device ensures that the tip of the nozzle remains at or very near the meniscus of the rising cement column so that the cement flows primarily radially into the cavity by withdrawing the nozzle into the canister as the cement is injected. Additionally, a pressure release mechanism permits the syringe to migrate as a unit independently of the retracting assembly to maintain the tip of the nozzle at the meniscus of the rising cement column.
