SPECIAL FOCUS: Hip Reconstruction

Purpose of review Modular hip replacements for chronic arthritis or acute fractures of the femoral neck are becoming increasingly popular as surgeons and patients learn of the advantages of modular designs.

Recent findings Modular components are easier to insert and cause less tissue damage as they are inserted. The variety of stems and necks that can be mixed, matched, and selected for optimum prosthetic placement at the time of surgery also leads to faster recovery and better outcomes. These factors also decrease the cost of the procedure, which is a major consideration as surgeons face an aging population with a greatly increased need of hip replacements for degenerative disease and fractures.

Summary Since the publications on modular hips are still few, the exact results on these joints have not been quantified, but it is important for surgeons to conscientiously and honestly report their experience and results with the newer designs. It is our opinion that the initial impressions about improved outcomes will prove to be correct in the next few years.
