Taylor Spatial Frame

A circular external fixator used in orthopedic surgery

The Taylor Spatial Frame (TSF) is a sophisticated external fixator used in orthopedic surgery to treat complex fractures, limb length discrepancies, and deformities. It is a versatile device that allows for precise adjustments in multiple planes, making it particularly useful in correcting angular deformities and rotational deformities.

Design and Components

The Taylor Spatial Frame consists of two or more circular rings connected by six adjustable struts. These struts can be lengthened or shortened to change the position of the rings relative to each other. The rings are attached to the bone using bone screws or wires, which are inserted through the skin and into the bone.

Rings

The rings are typically made of lightweight materials such as aluminum or carbon fiber, which provide strength while minimizing weight. The number of rings used depends on the complexity of the deformity being treated.

Struts

The struts are the key components that allow for the adjustment of the frame. Each strut can be independently adjusted, allowing for precise control over the position and orientation of the bone segments. The struts are calibrated, and adjustments are made according to a pre-determined plan based on the patient's specific needs.

Indications

The Taylor Spatial Frame is indicated for a variety of orthopedic conditions, including:

• Complex fractures that are not amenable to internal fixation
• Limb lengthening procedures
• Correction of angular deformities
• Treatment of nonunions and malunions
• Bone transport procedures

Principles of Operation

The operation of the Taylor Spatial Frame is based on the principles of Ilizarov technique, which involves gradual distraction of bone segments to stimulate osteogenesis. The frame allows for controlled and precise adjustments, which are typically made on a daily basis according to a pre-determined schedule.

Planning and Adjustment

Before the application of the frame, a detailed plan is created using computer software that calculates the necessary adjustments to achieve the desired correction. This plan takes into account the specific deformity and the anatomical considerations of the patient.

Adjustments are made by lengthening or shortening the struts according to the schedule. These adjustments are usually performed by the patient or a caregiver, under the guidance of the treating physician.

Advantages

The Taylor Spatial Frame offers several advantages over traditional external fixators:

• Allows for correction in multiple planes
• Provides stability while allowing for bone healing
• Can be adjusted without the need for additional surgery
• Reduces the risk of joint stiffness by allowing for early weight-bearing and joint movement

Complications

As with any medical device, the use of the Taylor Spatial Frame can be associated with complications, including:

• Pin site infections
• Nerve injury
• Joint stiffness
• Delayed union or nonunion
