Favorable Radiographic and Early Postoperative Results with the Inguinal Crease Direct Anterior Total Hip Arthroplasty.

We report the results, scar appearance, and patient satisfaction of a direct anterior approach total hip arthroplasty performed through an oblique inguinal incision. Patients were separated into direct anterior THA (n = 29) or an oblique inguinal incision anterior approach (n = 41). Clinical and radiographic data was compared, scar appearance was assessed by the Vancouver Scar Scale (VSS), and satisfaction was assessed by a simple questionnaire. Harris Hip Scores significantly improved in each group (1.8×10-8) and improved similarly between groups (p ≥ 0.35). The VSS score was lower in the inguinal incision versus the standard incision group (0.68 [range 0-3] vs. 1.56 [range 0-4], p = 0.015). Scar satisfaction was higher in the inguinal incision group with 87% compared to only 32% in the standard approach. The inguinal incision approach was safe, offered similar postoperative results, and resulted in improved patient scar satisfaction compared to the standard anterior approach by using an incision that more closely resembled normal anatomy.

Adverse Reaction to Zirconia in a Modern Total Hip Arthroplasty with Ceramic Head.

Hypersensitivity reactions to zirconia (ZrO2) or similar ceramics is highly unusual. Owing to the stable oxide formed between the base metal and oxygen, ceramics are considered relatively biologically inert. We report the case of an otherwise healthy 50-year-old woman with a 5-year history of progressively worsening right hip pain who underwent a ceramic-on-polyethylene total hip replacement and subsequently developed hypersensitivity reaction. After metal allergy testing showed her to be highly reactive to zirconium, the femoral head was revised to a custom titanium implant and her symptoms resolved.
