Dynamic Axial Hip Joint Traction External Fixator: An Effective Treatment for Proximal Femoral Fractures

Proximal femoral fractures are a common injury, particularly among the elderly population. These fractures can significantly impact a person's quality of life, making it difficult to walk, stand, and perform daily activities. While there are various treatment options available for proximal femoral fractures, dynamic axial hip joint traction external fixator (DAPHT) has emerged as an effective alternative to traditional treatments such as hip screws and intramedullary nails.

What is Dynamic Axial Hip Joint Traction External Fixator (DAPHT)?

DAPHT is an external fixation device that is used to stabilize and align the proximal femur after a fracture. The device consists of two pins that are inserted into the femoral head and neck, and a connecting rod that applies traction to the fracture site. The pins are typically placed under fluoroscopic guidance to ensure proper placement and alignment. The device is designed to allow controlled movement of the fracture site, which promotes bone healing and prevents complications such as non-union and implant failure.

How does DAPHT work?

DAPHT works by applying dynamic axial traction to the proximal femur. The device is designed to allow controlled movement of the fracture site, which promotes bone healing and prevents complications such as non-union and implant failure. The traction force is applied through a connecting rod that is attached to the pins that are inserted into the femoral head and neck. The traction force can be adjusted to ensure optimal alignment and healing of the fracture.

Advantages of DAPHT over Traditional Treatments

DAPHT has several advantages over traditional treatments such as hip screws and intramedullary nails. One of the main advantages is that it allows controlled movement of the fracture site, which promotes bone healing and prevents complications such as non-union and implant failure. Additionally, DAPHT is less invasive than traditional treatments, which can reduce the risk of infection and other complications. DAPHT also allows for earlier weight-bearing compared to traditional treatments, which can lead to faster recovery times and improved outcomes.

Surgical Technique for DAPHT

The surgical technique for DAPHT involves the following steps:

1. The patient is placed under general anesthesia and positioned on a fracture table.

2. The fracture is reduced under fluoroscopic guidance.

3. Two pins are inserted into the femoral head and neck under fluoroscopic guidance.

4. A connecting rod is attached to the pins, and traction is applied to the fracture site.

5. The traction force is adjusted to ensure optimal alignment and healing of the fracture.

6. The wound is closed, and the patient is monitored in the recovery room.

Risks and Complications of DAPHT

While DAPHT is generally considered safe and effective, there are risks and complications associated with the procedure. These include infection, pin tract infection, nerve injury, blood vessel injury, and implant failure. Your orthopedic surgeon will discuss these risks with you and help you make an informed decision about the most appropriate treatment for your fracture.

Conclusion

DAPHT is an effective alternative to traditional treatments for proximal femoral fractures. The device allows controlled movement of the fracture site, promotes bone healing, and allows for earlier weight-bearing compared to traditional treatments. While there are risks and complications associated with the procedure, DAPHT is generally considered safe and effective. Your orthopedic surgeon can help you determine the most appropriate treatment for your fracture based on your individual needs and circumstances.

FAQs

1. How long does it take to recover from DAPHT surgery?

Recovery time varies depending on the severity of the fracture, the patient's overall health, and other factors. In general,patients can expect to be non-weight-bearing for several weeks after surgery and will gradually begin to put weight on the affected leg as healing progresses. It can take several months for the bone to fully heal, and rehabilitation may continue for several months after that.

1. Is DAPHT suitable for all types of proximal femoral fractures?

DAPHT is most commonly used for stable, displaced proximal femoral fractures in elderly patients. However, your orthopedic surgeon will determine whether DAPHT is appropriate for your specific fracture based on various factors such as the severity and location of the fracture, your age, and overall health.

1. What should I expect during the DAPHT surgery?

During the surgery, you will be under general anesthesia, and the surgeon will make small incisions in the skin to insert the pins and connecting rod. You may experience some discomfort and pain after the surgery, but this can be managed with pain medication.

1. How long do the pins need to stay in place?

The pins typically remain in place for several weeks to several months, depending on the severity of the fracture and the rate of bone healing. Your orthopedic surgeon will monitor your progress and determine when the pins can be removed.

1. What are the alternatives to DAPHT for treating proximal femoral fractures?

Traditional treatments such as hip screws and intramedullary nails are alternative treatments for proximal femoral fractures. Your orthopedic surgeon will help you determine the most appropriate treatment for your fracture based on various factors such as the severity and location of the fracture, your age, and overall health.
