Comment:
Rear delivery is the poorest method of delivery in two-handed function. More often than not, rear-delivery systems encourage operators to extensively reach, lean, or twist their torsos to retrieve instruments from behind the patient's head, which can contribute to low-back pain. Operators should try to retrieve instruments with the closest (nondominant) hand to avoid repeated twisting or reaching across the body and then transfer the instrument to the dominant hand. If rear delivery rooms are designated for even a moderate amount of two-handed use, they should be reconfigured to an alternative delivery system.
