Introduction
The Short Medacta Stem (SMS) is designed for Total Hip Arthroplasty (THA) to optimize the reconstruction of individual anatomy and biomechanics. It addresses the challenges of a growing patient population requiring THA.

Design and Features
The SMS is a bone-preserving, short metaphyseal-fitting, cementless femoral stem. It is designed for physiological proximal load transfer and anatomical restoration. The design is based on anthropometric data from the MyBody database.

Material and Coating
Made from Ti-6Al-7Nb Alloy, the SMS features a sandblasted surface with a roughness of 2.5 to 6 µm. It includes a 300 µm MectaGrip coating and an 80 µm hydroxyapatite outer layer, enhancing the bone-implant interface.

Optimized Fit and Performance
The SMS's shortened length and reduced distal geometry preserve bone tissue and facilitate easy insertion. Its triple tapered design ensures axial and rotational stability, while the anatomical curvature enhances load transfer and reduces fracture risk.

Size Range and Compatibility
The SMS offers 13 standard and 13 lateralized sizes, maintaining leg length consistency. It is compatible with minimally invasive surgery (MIS) techniques, particularly the AMIS approach.

AMIS Experience
The AMIS technique, developed in collaboration with expert surgeons, optimizes the anterior approach for THA, reducing the risk of damage to periarticular structures. The AMIS Experience includes a comprehensive set of services for healthcare efficiency.

Conclusion
The SMS, as part of the P-Family Hip System, provides a valuable solution for patients with good bone quality, especially young and active individuals. Its design supports MIS procedures and offers extensive size options for diverse patient needs.
