May facilitate hip arthroscopy access with less traction; leaves open validation before practice change.
Iatrogenic injury is a known complication of initial portal placement during hip arthroscopy. The rate of labral puncture or damage to the articular surfaces with arthroscopic instruments is variable and may be associated with operator inexperience or complex anatomy. In addition, the amount of traction applied to achieve joint distraction may unnecessarily place patients at risk of neurapraxia. The purpose of this article is to describe the "femoral head drop" technique as a method to increase safe access to the central compartment and minimize the amount of traction needed to do so, especially in patients with challenging bony anatomy. This technique uses the application of intra-articular saline solution to cause inferior migration of the femoral head. Intra-articular fluid distension, or the femoral head drop technique, is simple, safe, and reproducible, making it appropriate for hip arthroscopists at any level of experience.

Alpaugh et al. (2015) studied Hip arthroscopy. Femoral head drop technique (intra-articular fluid distension) was evaluated. The femoral head drop technique using intra-articular saline solution provides a simple and safe method to increase access to the central compartment and minimize traction during hip arthroscopy.
