From the Guidelines
For surgical correction of lower limb length discrepancy, Taylor Spatial Frames (TSF) are generally preferred over standard Ilizarov frames due to their superior precision and versatility. However, the provided evidence does not directly compare TSF frames with standard Ilizarov frames in the context of lower limb length discrepancy correction [ 1 ]. The study [ 1 ] discusses the management of X-linked hypophosphataemia, which may involve lower limb deformities, but it does not provide a direct comparison between TSF and Ilizarov frames. Despite the lack of direct evidence, TSF frames are often chosen for their ability to correct multiplanar deformities through computerized planning and adjustments, which can be beneficial in complex cases of lower limb length discrepancy. Some key considerations when choosing between TSF and standard Ilizarov frames include:
- The complexity of the deformity
- Surgeon experience with each type of frame
- Cost constraints
- Patient compliance with adjustment protocols Both TSF and Ilizarov frames require meticulous pin site care and physical therapy throughout treatment to prevent infection and maintain joint mobility and muscle strength. In clinical practice, the decision between TSF and standard Ilizarov frames should prioritize the patient's specific needs and the surgeon's expertise, even in the absence of direct comparative evidence [ 1 ].
From the Research
Comparison of TSF and Ilizarov Frames
- The Taylor Spatial Frame (TSF) and Ilizarov ring fixator (IRF) are two external fixation systems used in the surgical correction of lower limb length discrepancy and deformity.
- A study published in 2007 2 compared the accuracy of deformity correction between the TSF and IRF, and found that the TSF achieved higher percentages of excellent results, particularly in two-, three-, and four-dimensional deformity corrections.
- The TSF allowed for more precise simultaneous multiplanar deformity corrections, with a success rate of 90.7% compared to 55.7% for the IRF.
Advantages of TSF
- The TSF combines a rigid hexapod fixation system with a web-based software program, enabling precise simultaneous corrections of multidirectional deformities 2, 3.
- The TSF has been shown to be effective in treating complex lower-limb deformities, with excellent results in 18 out of 22 cases in one study 4.
- The use of internet-based software with the TSF provides an instant treatment plan for deformity correction, allowing for accurate and efficient treatment 3.
Ilizarov Frame
- The Ilizarov ring fixator has been widely used for limb lengthening and deformity correction, with a long history of successful applications 5.
- However, the Ilizarov frame may have limitations in terms of precision and accuracy, particularly in complex deformity corrections 2.
- The Ilizarov frame has been compared to the TSF in several studies, with the TSF generally showing better results in terms of accuracy and success rate 2, 4.
