E X A C T E C H HIP Primary Femoral Solutions Developed for primary femoral solutions, the AlteonTM Neck Preserving Femoral Stem shares the proven features of conventional stems. Unlike traditional stems, the Neck Preserving Stem was designed to conserve more bone. Stability: Achieving initial mechanical stability is important to enable biologic fixation.1 Neck Preserving Femoral Stem Neck Preserving: A conservative treatment option, designed for maintaining the maximum amount of proximal femoral bone.2 Efficiency: With a curved geometry and broach-only system, the implant is designed to preserve host bone and follow the native anatomy.

TEST STUDY Quantified Volume and Native Femoral Neck Preserved with Neck Preserving Stem Compared to Two Traditional Total Hip Arthroplasty Stems* Nicholas J. Stroud (Exactech, Inc., Gainesville, FL, USA), John W. Aldridge (Hampton Roads Orthopaedics & Sports Medicine, Newport News, VA, USA), Scott J. Dunitz (Tulsa Bone & Joint, Tulsa, OK, USA) Abstract Short femoral stems for total hip arthroplasty (THA) have garnered increased popularity over the last decade due to promising short-term clinical and biomechanical success. Initial findings support claims that metaphyseal fixed short stems preserve...
