Abstract Aim The correction accuracy of the Taylor Spatial Frame (TSF) fixator depends considerably on the precise determination of the mounting parameters (MP). Incorrect parameters result in secondary deformities that require subsequent corrections. Different techniques have been described to improve the precision of MP measurement, although exact calculation is reportedly impossible radiologically. The aim of this study was to investigate the accuracy of intraoperative and postoperative radiographic measurement methods compared to direct MP measurement from TSF bone mounting. Methods A tibial Sawbone® model was established with different origins and reference ring positions. First, reference MPs for each origin were measured directly on the frame and bone using a calibrated, digital vernier calliper. In total 150 MPs measured with three different radiographic measurement techniques were compared to the reference MPs: digital radiographic measurements were performed using soft-copy PACS images without (method A) and with (method B) calibration and calibrated image intensifier images (method C). Results MPs measured from a non-calibrated X-ray image (method A) showed the highest variance compared to the reference MPs. A greater distance between the origin and the reference ring corresponded to less accurate MP measurements with method A. However, the MPs measured from calibrated X-ray images (method B) and calibrated image intensifier images (method C) were intercomparable (p = 0.226) and showed only minor differences compared to the reference values but significant differences to method A (p < 0,001). Conclusion The results demonstrate that MPs can be accurately measured with radiographic techniques when using calibration markers and a software calibration tool, thus minimizing the source of error and improving the quality of correction.

Abstract Background: The Taylor spatial frame (TSF) is increasingly used for acute tibial shaft fracture care as more general orthopedic surgeons are gaining expertise of this versatile device. The purpose of this study was to evaluate the clinical effectiveness of the TSF for fracture reduction and definitive management in patients with acute tibial shaft fractures.Methods: The study was conducted on 34 patients with acute tibial shaft fractures who were admitted or referred to our institution and consented to TSF treatment from Jan 2016 to June 2019, including 27males and 7 females with a mean age of 39 years (range 18 to 65 years). Patients' clinical and radiological data, and the final clinical outcomes at a minimum of 12 months follow-up were collected and retrospectively analyzed. All complications were documented according to Paley’s classification. The clinical outcomes were evaluated using the Association for the Study and Application of the Method of Ilizarov criteria (ASAMI) at the last clinical visit.Results: All patients remained in the TSF for a mean of 26 weeks (range 15 to 52 weeks) and acquired complete bone union. The satisfactory alignment was achieved in all patients, and all the patients were able to perform daily activities with no difficulty at the last clinical visit. Complications included pin tract infection (44%), delayed union (6%), nonunion (3%), and joint stiffness (3%). The ASAMI bony result was excellent in 31 patients and good in 3. The ASAMI functional result was excellent in 27 patients, good in 6, and fair in 1. Conclusions: Fracture reduction and definitive management using the Taylor spatial frame is an alternative and effective method for acute tibial shaft fractures, including technical advantages of early trauma-control, ease of soft tissue care, the versatility of achieving excellent alignment, and the continuity of device until bone union.

Congenital pseudarthrosis of the tibia remains one of the most difficult conditions in pediatric orthopedic surgery. The numerous treatment options reflect this difficulty. The aim of successful treatment is to achieve union, length and deformity correction. This reports a 16-years-old male patient with congenital pseudarthrosis of the tibia diagnosed at age of two years, who previously underwent 14 different operations. The patient was referred to King Abdulaziz University Hospital, where he was treated with Taylor Spatial Frame, excision of pseudarthrosis, autogenus bone grafts and Demineralized Bone Matrix was performed, and union was achieved. Stability and deformity correction permitted by Taylor Spatial Frame, in addition to stimulation of bone healing through proper grafting provided a successful option to treat this complex condition.
