Zimmer Features New CLS® Brevius Stem with Kinectiv® Technology at EFORT Congress

Zimmer Holdings, Inc. (NYSE and SIX: ZMH), a global leader in musculoskeletal care, today introduced its CLS Brevius Stem with Kinectiv Technology at the 12th annual European Federation of National Associations of Orthopaedics and Traumatology (EFORT) meeting in Copenhagen, Denmark. The new hip stem is based on the CLS Spotorno Stem, one of the most reliable implants worldwide [1-3] with more than 25 years of clinical use. The new hip stem writes the next chapter in CLS Spotorno Stem history with the addition of Kinectiv Technology. This technology enables surgeons to better match patients' individual needs with modular neck options designed for independent intra-operative adjustments.

The CLS Spotorno Hip Stem is a pioneering system for uncemented total hip arthroplasty characterized by excellent primary and rotational stability. Since its introduction in the 1980s, the CLS Spotorno Stem has been used in more than 560,000 total hip arthroplasty procedures around the world [4]. The stem has been optimized to accommodate a variety of patients' anatomies and to bring great intraoperative flexibility.

Intra-Operative Flexibility with Kinectiv Technology

Expanding the CLS Spotorno Stem technology through a modular neck approach combines a proven concept with more than 25 years of clinical success with the intra-operative flexibility of modular neck options. Kinectiv Technology offers a wide array of head center locations allowing for an independent, intra-operative control of leg length, offset and version for a more accurate restoration of the patient's natural anatomy. The CLS Brevius Stem with Kinectiv Technology is shorter than conventional stems, providing greater bone conservation compared with the original CLS Spotorno Stem.

Documented Long-Term Reliability

The CLS Stem's capacity for osseointegration has been demonstrated in a number of clinical studies with follow-up periods up to 20 years [2, 3, 5, 7]. The Swedish Hip Arthroplasty Registry documents a 97.5% survival rate at 16 years postoperative [1]. Consistently, Muller et al. found a stable stem fixation in 98.8% of the operated hips 17 years after implantation [3]. All of these studies, together with the results of other clinical investigations, some of which encompass follow-up periods of up to 20 years [7], confirm that revision surgery after implantation of the CLS Spotorno Hip Stem body is a rare event - again demonstrating the excellent longevity of this implant with long-time survival rates.

Kinectiv Technology can already look back on initial periods of clinically proven success. The results indicate that the design of the Kinectiv Neck Implants not only gives the flexibility surgeons need to address a wide range of patient anatomies but also meets the stringent strength requirements. In a 2-year follow-up multicenter study conducted on 634 patients, Duwelius et al. were not able to find any complications related to femoral implant nor fractures of a stem or modular necks or dissociations of the nead-neck junction [6].
