Vertical or Horizontal (Bikini) Incision for Direct Anterior Total Hip Arthroplasty: Outcomes of Early (<90 day) Revision.

Background: The horizontal 'bikini' incision for direct anterior approach (DAA) total hip arthroplasty has gained popularity due to its early wound healing characteristics; however, the nonextensile nature of this approach may pose problems in treating early complications. This study sought to characterize the outcomes of early revision (<90 days) in patients who underwent anterior hip arthroplasty utilizing either a traditional longitudinal incision or a horizontal (bikini) incision.

Methods: This retrospective study identified patients who underwent DAA primary total hip arthroplasty with a subsequent DAA revision within 90 days.

Methylene Blue Infiltration As a Method for Distinguishing Superficial and Deep Infections.

Background: There are no established objective methods to reliably differentiate between superficial and deep infection in the setting of total hip arthroplasty. We employed a technique of distinguishing superficial and deep infections by infiltrating methylene blue to a prosthetic hip during infection workup to determine its effectiveness and to characterize its utility in defining the joint cavity where deep debridement is required.

Methods: An analysis was conducted on 35 patients who preoperatively received an injection of methylene blue under radiological guidance to their total hip arthroplasty.
