The Consistency Between Scientific Papers Presented at the Orthopaedic Trauma Association and their Subsequent Full-Text Publication. Journal of Orthopaedic Trauma. 20(2):129-133, February 2006. Preston, Charles F MD *; Bhandari, Mohit MD, MSc, FRCSC +; Fulkerson, Eric MD *; Ginat, Danial BS *; Egol, Kenneth A MD *; Koval, Kenneth J MD ++ Abstract: Objectives: To determine the consistency of conclusions/statements made in podium presentations at the annual meeting of the Orthopaedic Trauma Association (OTA) with those in subsequent full-text publications. Also, to evaluate the nature and consistency of study design, methods, sample sizes, results and assign a corresponding level of evidence. Data Sources: Abstracts of the scientific programs of the OTA from 1994 to 1997 (N = 254) were queried by using the PubMed database to identify those studies resulting in a peer-reviewed, full-text publication. Study Selection: Of the 169 articles retrieved, 137 studies were the basis of our study after the exclusion criteria were applied: non-English language, basic science studies, anatomic dissection studies, and articles published in non-peer-reviewed journals. Data Extraction/Synthesis: Information was abstracted onto a data form: first from the abstract published in the final meeting program, and then from the published journal article. Information was recorded regarding study issues, including the study design, primary objective, sample size, and statistical methods. We provided descriptive statistics about the frequency of consistent results between abstracts and full-text publications. The results were recorded as percentages and a 95% confidence interval was applied to each value. Study results were recorded for the abstract and full-text publication comparing results and the overall conclusion. A level of scientific-based evidence was assigned to each full-text publication. Results: The final conclusion of the study remained the same 93.4% of the time. The method of study was an observational case series 52% of the time and a statement regarding the rate of patient follow-up was reported 42% of the time. Of the studies published, 18.2% consisted of a sample size smaller than the previously presented abstract. When the published papers had their level of evidence graded, 11% were level I, 16% level II, 17% level III, and 56% level IV. Conclusions: Authors conclusions were consistent with those in full-text publications. Most studies were observational, less than half reported on the rate of patient follow-up. Many abstracts followed by publication had a smaller sample size in the published paper. Half of all studies were graded level IV evidence.

AAOS Scientific Exhibit 2006 Tibial Osteotomy and Deformity Correction With the Ilizarov/Taylor Spatial Frame: Clinical Experience, Surgical Planning, Video Surgical Demonstration, and Computer Animation Scientific Exhibit Number: SE26 Location: McCormick Place Hall B Adult Reconstruction Knee S Robert Rozbruch, MD New York NY (a - Smith & Nephew Inc.)

In this exhibit, we will present our clinical experience with tibial osteotomy, surgical planning, the deformity correction software, a video surgical demonstration, and a computer animation. The Taylor Spatial Frame (TSF) is an evolution of the classic Ilizarov frame. It utilizes a computer program, which helps calculate a schedule for gradual strut and frame adjustment to simultaneously correct multiple aspects of deformity around a virtual hinge without the need for complicated frame modification. In this exhibit, we will present our clinical experience, surgical planning, the deformity correction software, a video surgical demonstration, and a computer animation. Forty-two patients (50 tibiae) underwent osteotomy surgery for deformity correction using the Taylor Spatial Frame between 2000 and 2003. Malunion was the most common etiology (23 limbs). Other causes included developmental deformity such as genu varum (19 limbs) or genu valgum (4 limbs) with pain and/or osteoarthritis, congenital deformity (2) and neurologic disorders (2). The osteotomy was performed near the apex of the deformity, which was at the proximal tibia in 33, middle tibia in 9 and distal tibia in 8. Varus angulation was the most common deformity. Mechanical axis deviation (MAD) and joint orientation angles were used to evaluate the deformity. Rotational deformity was assessed clinically. Twenty-five patients had leg length discrepancy with 3.1cm average (range: 0.4 -22 cm). Tibia and fibula osteotomies were performed for deformity correction. Double level osteotomy was performed on one tibia. Planned deformity correction in different planes was achieved in all cases using TSF The average medial MAD improved from 28 mm to 4 mm medial or to 7 mm lateral in cases with hypercorrection. The average lateral MAD improved from 42 mm to 0 and in cases of osteoarthritis was overcorrected to 9 mm medial to midline to unload affected compartment of the knee. Simultaneous lengthening of 2.1 cm was done in 14 patients (16 limbs). Average time in a frame was 131 days and there were no nonunions. Osteotomy of the tibia and fibula and the use of the Ilizarov/ Taylor Spatial Frame can be used effectively to correct leg deformities. All aspects of deformity are addressed including length. This technique uses a minimally invasive approach and gradual deformity correction.
