Technique, patient and implant selection key to avoiding fracture during THA

At the Current Concepts in Joint Replacement 2011 Winter Meeting, Craig J. Della Valle, MD, provided tips on the prevention of intraoperative fractures during total hip arthroplasty.

“Prevention is key,” Della Valle said, noting that appropriate exposure is crucial.

In a study of more than 5,000 hip replacements performed by 11 surgeons during a 10-year period, Della Valle and colleagues found that risk factors for fracture include elderly patients, female patients and type of stem used. He noted that flat-wedge taper designs have a high risk for early postoperative and intraoperative fracture. Developmental dysplasia of the hip was also substantial risk factor.

The decision to use a cemented or uncemented implant is also key.
