1. Introduction: What is a short stem in a hip prosthesis?

The term "short stem" refers to a special type of hip prosthesis that is less invasive than conventional long-stem prostheses. Short-stem prostheses are characterized by their shorter anchorage in the femur, which largely preserves the bone and optimizes the biomechanical function of the hip joint. This type of prosthesis is particularly suitable for younger patients or those with good bone substance who aim for a natural reconstruction of the hip joint.

A hip prosthesis generally consists of three components:

• Shaft: This part is anchored in the femur.
• Head: Replaces the femoral head and forms the new joint surface.
• Acetabulum: Implanted into the pelvis and forms the counter-surface to the prosthesis head.

Differences between short-stem and long-stem prostheses

Short-stem prostheses offer several significant differences compared to traditional long-stem prostheses:

1. Bone Preservation: A major advantage of the short-stem prosthesis is the greater preservation of bone. Since the stem is shorter, less bone material needs to be removed, which is particularly beneficial during later revisions or re-implantation of the prosthesis.
2. Anatomical adaptation: The short stem prosthesis is more closely aligned with the patient's natural anatomy. This enables a biomechanically optimized function of the hip joint, supporting natural freedom of movement.
3. Reduced invasiveness: The shorter stem allows for a more minimally invasive surgical procedure. This results in less tissue damage, a faster recovery phase, and a lower rate of postoperative complications.
4. Weight distribution: Since the short stem is anchored further up in the femur, the load is distributed over a larger area of the bone. This can make the prosthesis more stable and reduce the risk of complications such as loosening or fractures.

Benefits for different patient groups

The short-stem prosthesis is particularly well-suited for various patient groups:

• Younger patients: Due to the low bone loss, the short-stem prosthesis is ideal for younger patients who may require a revision of the prosthesis during their lifetime.
• Aktive Patienten: Patienten, die einen aktiven Lebensstil pflegen, profitieren von der höheren Stabilität und dem natürlichen Bewegungsumfang, den die Kurzschaftprothese bietet.
• Patients with good bone quality: Since the short stem prosthesis generally preserves more bone, it is particularly suitable for patients whose bone structure is healthy and robust.

Indications and contraindications

The indications for a short stem prosthesis include:

• Advanced osteoarthritis of the hip joint, in which the cartilage is severely worn out.
• Femoral head necrosis, in which the bone in the femoral head dies and impairs the shape and function of the joint.
• Severe fractures of the hip joint, where restoration of the natural joint function without a prosthesis is not possible.

Contraindications may be:

• Severely reduced bone quality, which complicates stable anchoring of the prosthesis.
• Severe deformations of the femur, which prevent an anatomical adaptation of the short-stem prosthesis.

The short stem prosthesis represents a modern, less invasive option for hip replacement, characterized by greater bone preservation, improved adaptation to the natural anatomy, and faster recovery after surgery. In particular, younger, active patients or those with good bone substance can significantly benefit from this type of prosthesis. The endoprosthetics department in Mainz has specialized in this innovative technique and offers comprehensive expertise in the use of short stem prostheses.



2. Development of Short-Stem Prostheses: A Look into the Past

The development of short-stem prostheses began in the 1980s, when orthopedic surgeons were looking for less invasive methods for joint replacement. In recent decades, the designs have continued to evolve, with an increasing focus on preserving bone and minimizing complications. Today, short-stem prostheses are among the most advanced and successful implants used in endoprosthetics.

5. Advantages of Short-Stem Prostheses over Traditional Prostheses

The short stem prosthesis offers numerous advantages compared to conventional long stem prostheses. These include less bone loss, better anatomical reconstruction, and higher stability of the implant. Patients often report faster recovery and higher satisfaction after surgery.

6. Indications for the use of a short stem prosthesis

The short stem prosthesis is particularly suitable for patients who are active and in good physical condition. It is ideally suited for younger patients who expect a long lifespan of the prosthesis, but also for older patients with sufficiently good bone quality.
