Synthes Plate Fractures: Know The Signs & Treatments!
Addressing synthes broad femoral plate periprosthetic fractures requires a comprehensive understanding of both the biomechanical principles involved and the potential complications that can arise. Synthes, a leading name in orthopedic implants, provides plates commonly used in fracture fixation. Periprosthetic fractures, specifically those occurring around a hip or knee replacement, present unique challenges. These challenges are frequently addressed by orthopedic surgeons specializing in Trauma Surgery, and their treatment protocols are often based on guidelines established by organizations like the Orthopaedic Trauma Association (OTA). Effective management relies on accurate diagnosis and the selection of appropriate fixation techniques, considering factors such as bone quality and fracture pattern.

Synthes Plate Fractures: Recognizing the Signs & Exploring Treatments
This article aims to provide clear and comprehensive information about fractures occurring around a hip replacement (periprosthetic fractures) specifically when a Synthes broad femoral plate has been used for previous fracture fixation. These fractures are complex and require specialized understanding.
Understanding Synthes Broad Femoral Plate Periprosthetic Fractures
Defining Periprosthetic Fractures
A periprosthetic fracture is a fracture of the bone around a joint replacement implant (in this case, a hip replacement). It occurs after the initial joint replacement surgery. When a patient with a prior femur fracture treated with a Synthes broad femoral plate undergoes a hip replacement, the area around the plate becomes susceptible to this type of fracture.
Role of the Synthes Broad Femoral Plate
The Synthes broad femoral plate is a specific type of orthopedic implant used to stabilize femur fractures. It is typically a long, strong metal plate that is attached to the bone with screws. Its purpose is to hold the fractured bone fragments together, allowing them to heal properly. The plate’s presence can alter the stress distribution in the femur, potentially increasing the risk of fracture at the ends of the plate after a hip replacement.
Why are Synthes Broad Femoral Plate Fractures Significant?
These fractures are often challenging to treat because:
- The presence of both the hip implant and the bone plate complicates surgical options.
- The bone quality around the implants may be compromised.
- The fracture pattern can be complex, involving the implant itself.
- Achieving stable fixation can be technically difficult.
Identifying the Signs and Symptoms
Recognizing the symptoms early is crucial for prompt diagnosis and treatment.
Common Signs and Symptoms
- Sudden onset of pain: Often located in the hip, groin, or thigh. The pain may be sharp and severe.
- Inability to bear weight: Difficulty or inability to stand or walk without significant pain.
- Deformity: Visible deformity of the leg or hip (rare, but possible).
- Swelling and bruising: Around the hip and thigh.
- Clicking or popping sensation: At the time of injury.
- Limb Length Discrepancy: The affected leg may appear shorter.
Factors that Increase Risk
Certain factors can increase the likelihood of developing a periprosthetic fracture around a Synthes plate:
- Osteoporosis: Weakened bones are more prone to fracture.
- Advanced age: Bones become more brittle with age.
- Previous fracture: A history of femur fracture already indicates underlying bone weakness.
- Revision hip surgery: Repeat hip replacement surgeries can weaken the surrounding bone.
- Trauma: A fall or direct blow to the hip.
- Loosening of the hip implant: This can place extra stress on the surrounding bone.
- Certain medications: Long-term use of corticosteroids can weaken bones.
Diagnosis: Confirming the Fracture
A thorough diagnosis is essential to determine the extent of the fracture and guide treatment.
Diagnostic Procedures
- Physical Examination: The doctor will assess your pain, range of motion, and overall condition.
- X-rays: The primary imaging technique to visualize the fracture. X-rays will show the location, pattern, and severity of the fracture in relation to the existing hip implant and the Synthes plate.
- CT Scan: Computed tomography (CT) scans provide more detailed images of the bone, implant, and fracture line. This is especially helpful for complex fracture patterns.
- Bone Scan: In some cases, a bone scan may be used to assess the bone’s activity and identify areas of increased stress.
Treatment Options
The treatment approach depends on several factors, including the type and location of the fracture, the stability of the hip implant, the patient’s overall health, and bone quality.
Non-Surgical Treatment
Non-surgical treatment is rarely an option for displaced periprosthetic fractures with a Synthes plate in place. It might be considered in very rare circumstances:
- Stable, undisplaced fractures: With minimal pain, a period of protected weight-bearing may be recommended with close monitoring.
- High surgical risk: Patients who are medically unfit for surgery.
Surgical Treatment
Surgery is typically required to stabilize the fracture and restore function.
- Revision Hip Arthroplasty: If the hip implant is loose, it may need to be replaced with a new implant. This can involve specialized stems that bypass the fracture site.
- Open Reduction and Internal Fixation (ORIF):
- This involves surgically exposing the fracture site and realigning the bone fragments.
- The fracture is then stabilized with plates, screws, or cables.
- Considerations for Synthes plates: The existing Synthes plate may be incorporated into the new fixation construct, removed and replaced, or left in place depending on its location and the fracture pattern.
- Femoral Bone Grafting: If there is significant bone loss, bone grafting may be necessary to promote healing. This can involve using bone from the patient’s own body (autograft) or from a donor (allograft).
- Distal Femoral Replacement: In cases with significant comminution and poor bone stock, a distal femoral replacement might be considered.
Specific Surgical Considerations
When deciding on the best surgical approach, the following are crucial:
- Fracture Location and Pattern: Dictates the type of fixation.
- Hip Implant Stability: Loose implants require revision.
- Bone Quality: Poor bone quality may necessitate specialized implants and techniques.
- Condition of the Synthes plate: Its location relative to the fracture, its stability, and its impact on the new fixation.
Rehabilitation
Regardless of the chosen treatment, rehabilitation is essential for regaining strength, mobility, and function.
- Physical Therapy: Focuses on strengthening the muscles around the hip and leg, improving range of motion, and restoring balance and coordination.
- Occupational Therapy: Helps with activities of daily living, such as dressing, bathing, and cooking.
- Assistive Devices: Crutches, walkers, or canes may be needed initially to protect the healing bone.
- Weight-bearing Progression: Gradually increasing the amount of weight placed on the leg as the fracture heals. The surgeon will provide specific instructions on weight-bearing restrictions.

Synthes Plate Fractures: FAQs
Synthes plates are a common solution for bone fractures, but sometimes complications arise. Here are some frequently asked questions to clarify the signs and treatments of Synthes plate fractures.
What are the common causes of a Synthes plate fracture?
Synthes plates can fracture due to various reasons, including excessive stress on the implant, non-union of the original fracture, or new trauma to the area. For instance, a fall could lead to a synthes broad femoral plate periprosthetic fracture if the bone around the implant is already weakened.
How do I know if my Synthes plate is fractured?
Symptoms of a fractured Synthes plate can vary. You might experience increased pain, swelling, and instability around the fracture site. A cracking or popping sound might also be audible. X-rays are usually necessary for a definitive diagnosis.
What are the treatment options for a Synthes plate fracture?
Treatment depends on the severity and location of the fracture. Options range from conservative management with immobilization to surgical intervention. Surgery might involve plate replacement, bone grafting, or revision of the original fixation, particularly in cases of synthes broad femoral plate periprosthetic fracture.
Can a Synthes plate fracture lead to further complications?
Yes, if left untreated, a fractured Synthes plate can lead to delayed or non-union of the original fracture, infection, and increased pain and disability. In some cases, adjacent bone can be affected as well, leading to additional fractures, like synthes broad femoral plate periprosthetic fracture, which need more extensive surgical interventions.
So, if you or someone you know is dealing with a synthes broad femoral plate periprosthetic fracture, remember that knowledge is power! Stay informed and consult with your healthcare team for the best possible outcome.
