Paxeon Reconstruction, a manufacturer of best-in-class orthopedic products including derivative and emerging products, announces that Dr. Christian Christensen has completed a retrospective study that included 579 patients during a one-and-a-half-year period with at least three months follow-up on each patient.

Postoperative peri-prosthetic fractures are a common complication of direct anterior total hip arthroplasty. These femoral fractures generally require complex femoral revision. Dr. Christensen of Lexington, Kentucky has compared surgical outcomes of the anterior approach with two different implants. His results suggest that femoral implant design affects peri-prosthetic fracture rate following direct anterior total hip arthroplasty. These results were recently presented at the 9th Annual Emily Berend Adult Reconstruction Symposium at Duke University in Durham, NC in March 2016.

From February 2015 through June 2016, Dr. Christensen performed a total of 381 direct anterior total hip replacements using the flat tapered wedged femoral implant. In June of 2016, Dr. Christensen began utilizing the Origin by Paxeon Reconstruction. Origin is a dual taper, hydroxyapatite coated implant that was used in a total of 198 consecutive, anterior hips.

Each patient was monitored for three months after surgery to identify the frequency of peri-prosthetic femur fractures in each group. In the first cohort, 5 out of 381 patients (1.3%) sustained femur fractures at an average of 19.6 days after surgery. All five of these patients had a Vancouver type B2 fracture and required femoral revision. However, in the second cohort, when using the Origin, no patients sustained femoral fractures. These results suggest that using the Origin stem when doing the anterior approach will result in a lower postoperative fracture rate.

The Origin by Paxeon Reconstruction showed a reduced fracture rate than a plasma sprayed, flat-taper, wedged design. Dr. Christensen’s group continues to accumulate data and plans to submit the findings to the Journal of Arthroplasty this fall when the data reaches a clinically significant value.

Kyle Sineath, President of Paxeon Reconstruction said: “We are thankful to Dr. Christensen for bringing to light the fact that our implants can reduce or eliminate postoperative peri-prosthetic fractures as a complication of direct anterior total hip arthroplasty.”
