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

The term "short stem" refers to a specific 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 quality who desire the most natural possible 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.
• Joint socket: It is implanted into the pelvis and forms the opposite surface to the prosthetic head.

Differences between short-stem and long-stem prostheses

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

1. Bone preservation: A major advantage of short-stem prostheses is greater bone preservation. Because the stem is shorter, less bone material needs to be removed, which is particularly beneficial in 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 biomechanically optimized hip joint function, which supports natural range of motion.
3. Reduced invasiveness: The shorter shaft allows for a minimally invasive surgical procedure. This results in less tissue damage, a faster recovery, and a lower rate of postoperative complications.
4. Weight distribution: Because the short stem is anchored higher 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 minimal bone loss, the short stem prosthesis is ideal for younger patients who may require a revision of the prosthesis during their lifetime.
• Active patients: Patients who lead an active lifestyle benefit from the increased stability and natural range of motion offered by the short stem prosthesis.
• Patients with good bone quality: Since the short stem prosthesis usually 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.
• Avascular necrosis of the femoral head, 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 natural joint function is not possible without a prosthesis.

Contraindications may include:

• Severely reduced bone quality, which makes stable anchoring of the prosthesis difficult.
• Severe deformities of the femur that prevent 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 postoperative recovery. Younger, active patients or those with good bone density, in particular, can benefit significantly from this type of prosthesis. The Endoprostheticum in Mainz specializes in this innovative technique and offers comprehensive expertise in the application 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 sought less invasive methods for joint replacement. Over the past few decades, the designs have continuously evolved, with increasing emphasis on bone preservation and minimizing complications. Today, short-stem prostheses are among the most advanced and successful implants used in joint replacement surgery.

5. Advantages of short-stem prostheses compared to traditional prostheses

Short-stem prostheses offer numerous advantages compared to conventional long-stem prostheses. These include less bone loss, better anatomical reconstruction, and greater implant stability. Patients often report faster recovery and greater 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 ideal for younger patients who expect a long prosthesis lifespan, but also for older patients with sufficiently good bone quality.
