A 60-year-old female underwent hybrid total hip arthroplasty with good position of implants and post-operatively is instructed not to extend, adduct, and externally rotate the hip to prevent dislocation. What approach was likely performed?
Select Answer to see Preferred Response
The position to dislocate a hip anteriorly is extension, adduction, and external rotation which is the position at risk after an anterior approach. Hips are most likely to dislocate the direction of the approach assuming the implants are correctly positioned. Other important variables to THA stability include: component design, component alignment, soft-tissue tensioning, and soft tissue function.
