Hip fractures are among the most common orthopedic injuries, especially in elderly patients suffering from osteoporosis or reduced bone density. Timely surgical intervention is crucial to restore mobility, reduce pain, and improve the patient’s quality of life. Among the various Orthopaedic implants available today, the Thompson hip prosthesis has remained a reliable and widely used implant for hemiarthroplasty procedures. Its simple design, proven clinical performance, and durability make it one of the preferred choices for treating displaced fractures of the femoral neck.
Over the years, advancements in implant technology have introduced multiple prosthesis designs to suit different patient anatomies and surgical requirements. Products such as Thompson hip prostheses standard stem, thompson hip prostheses long neck, austin moore hip prostheses standard stem, austin moore hip prostheses extra-long stem, bipolar hip prostheses, lazcano hip prostheses, and shoulder prostheses continue to play an important role in modern orthopedic surgery.
What Is a Thompson Hip Prosthesis?
A Thompson hip prosthesis is a monoblock femoral implant designed for hemiarthroplasty. It replaces the femoral head while leaving the patient’s natural acetabulum intact. The implant is primarily indicated for elderly patients with displaced intracapsular fractures of the femoral neck where preserving the native femoral head is not feasible.
Unlike total hip replacement, hemiarthroplasty is generally less invasive, requires shorter operative time, and allows early mobilization. This makes the Thompson prosthesis particularly valuable for elderly patients with limited physiological reserves.
Manufactured from high-quality stainless steel, the prosthesis provides excellent strength, corrosion resistance, and long-term durability.
Evolution of Hip Prostheses
Hip replacement technology has evolved significantly over the past several decades. Early prostheses were relatively simple in design but offered remarkable improvements in pain relief and patient mobility.
Today, orthopedic surgeons can choose from various implant designs based on:
- Patient age
- Bone quality
- Femoral anatomy
- Activity level
- Type of fracture
- Surgical preference
Modern Hip implants include:
- Thompson Prosthesis
- Austin Moore Prosthesis
- Bipolar Prosthesis
- Cemented Hip Prosthesis
- Cementless Hip Prosthesis
- Modular Hip Systems
Each implant serves a specific purpose depending on clinical indications.
Thompson Hip Prostheses Standard Stem Stainless Steel
One of the most commonly used implants is the Thompson hip prostheses standard stem stainless steel.
Key Features
- High-grade stainless steel construction
- Anatomically designed stem
- Smooth polished surface
- Strong femoral fixation
- Excellent load transmission
- Long-lasting mechanical strength
The standard stem design is suitable for patients with normal femoral canal anatomy and provides dependable fixation with or without bone cement.
Its polished finish reduces tissue irritation while enhancing implant longevity.
Thompson Hip Prostheses Long Neck S.S.
Certain patients require additional neck length to restore normal biomechanics after surgery.
The thompson hip prostheses long neck s.s offers:
- Improved limb length restoration
- Better soft tissue tension
- Enhanced joint stability
- Reduced risk of postoperative dislocation
- Improved gait mechanics
Long neck options allow surgeons to optimize hip biomechanics without compromising implant stability.
Thompson Hip Prostheses Long Stem S.S.
Patients with osteoporosis, previous fractures, or widened femoral canals may benefit from the Thompson Hip Prostheses Long Stem S.S.
Advantages include:
- Increased stem stability
- Better load distribution
- Greater fixation within the femoral canal
- Improved support in compromised bone
- Reduced implant loosening
Long stem implants are particularly useful in revision cases or patients with poor proximal bone stock.
Surgical Indications
Thompson prostheses are commonly indicated for:
- Displaced femoral neck fractures
- Elderly low-demand patients
- Osteoporotic fractures
- Failed internal fixation
- Femoral head collapse
- Selected revision procedures
They are generally recommended when preserving the natural femoral head is not practical.
Surgical Procedure
Implantation involves several important steps:
Preoperative Planning
The surgeon evaluates:
- X-rays
- Femoral canal size
- Limb length
- Neck offset
- Patient anatomy
Femoral Head Removal
The fractured femoral head is carefully removed.
Canal Preparation
The femoral canal is broached and prepared for prosthesis insertion.
Implant Selection
Depending on anatomy, the surgeon selects:
- Standard stem
- Long neck
- Long stem
Implant Fixation
The prosthesis may be inserted:
- Cemented
- Cementless (selected cases)
Reduction
The implant head is reduced into the acetabulum and stability is confirmed.
Advantages of Thompson Hip Prosthesis
The popularity of Thompson prostheses stems from several clinical benefits.
Reliable Pain Relief
- Replacement of the damaged femoral head significantly reduces pain.
Early Mobilization
- Patients often begin rehabilitation within days after surgery.
Simple Surgical Technique
- The implant is easier to insert than modular total hip systems.
Lower Surgical Time
- Reduced operative duration benefits elderly patients.
Proven Clinical Performance
- Decades of successful use have established its reliability.
Durable Stainless Steel Construction
- High mechanical strength ensures long service life.
Austin Moore Hip Prostheses Standard Stem S.S.
The austin moore hip prostheses standard stem s.s. remains another widely recognized hemiarthroplasty implant.
Unlike Thompson prostheses, Austin Moore implants feature a fenestrated stem that encourages bone ingrowth.
Common indications include:
- Femoral neck fractures
- Elderly patients
- Low-demand individuals
Advantages include:
- Biological fixation
- Proven clinical history
- Excellent strength
- Reliable performance
Both Thompson and Austin Moore prostheses continue to be valuable options depending on surgeon preference and patient anatomy.

Extra-long stems reduce the likelihood of loosening in compromised femurs.
Bipolar Hip Prostheses Non-Fenestrated Stainless Steel
The bipolar hip prostheses non-fenestrated stainless steel represents a significant advancement over traditional hemiarthroplasty implants.
Unlike monoblock prostheses, bipolar implants feature two articulating surfaces:
- Inner articulation
- Outer articulation
Benefits include:
- Reduced acetabular wear
- Improved range of motion
- Better joint mechanics
- Lower dislocation rates
- Increased patient comfort
These implants are commonly selected for more active elderly patients.
Lazcano Hip Prostheses Narrow Stem S.S.
