“…This angle was defined as the “projected AVA.” This procedure was performed on the affected as well as the healthy femur. Values obtained were compared to the conversion table values published by Müller and Rippstein, [25] and the “real CCD angle” and “real AVA” were recorded for further analyses.…”

Elastic stabile intramedullary nailing (ESIN) is a well-established method to stabilize diaphyseal fracture of the femur (DFF) in children. We aimed to evaluate the minimal medullary canal diameter (MMCD) of the fractured femur relative to the diameter of the nails. We also analyzed the real anteversion angle (AVA) of the affected femur in comparison to the healthy femur. We retrospectively reviewed the medical records and plain X-ray images of children aged 2–15 years treated with ESIN for unstable femoral shaft fractures between 2004 and 2012. We measured MMCD on preoperative plain X-ray images. Nail diameter (ND) and any postoperative complications were extracted from the medical records. At follow-up conducted at a median of 40 months (range: 4–103 months) after the operation, we obtained Dunn X-ray images of both hips. Particular emphasis was placed on postoperative torsional differences in relation to age, weight, and maturity of the growth plate. We analyzed the relationship between postoperative rotational malalignment and the ratio of ND to MMCD. Median age of the 22 children at the time of injury was 7.5 years (range: 2–15 years). Median body weight was 25 kg (range: 13–57 kg). Median MMCD amounted to 8.6 mm (range: 5.5–11.0 mm). Median ND/MMCD was 36.9% (range: 27.3%–47.4%). Radiological analyses revealed a median of 27.0° (range: −22.0° to +49.0°) of real AVA in the affected leg and 32.5° (range: 18.0°–48.0°) in the healthy leg. Three children (13.6%) experienced a grade III complication (Clavien–Dindo classification of surgical complications; CDCSC). Two of these children suffered retrotorsion of the femoral neck, while the third child experienced diminished anteversion. Overall, 3 of 22 children (13.6%) suffered a CDCSC-grade III complication (i.e., retrotorsion of the femoral neck in two children and diminished anteversion of the femoral neck in one child). We recommend obtaining Dunn images at the end of the operation to confirm correct rotational alignment after stabilization with ESIN. Further prospective studies are required to confirm our findings.

To study the spontaneous regression of femoral anteversion, 30 children referred to the outpatient clinic for intoeing were followed until at least 15 years of age. The mean observation time was 9 (7-12) years, and all the children were examined three times during the growth period. The mean radiographic angle at the first examination was 42 degrees, at the second examination 36 degrees, and at the last examination 28 degrees. The mean decrease of the AV angle per year was 1.5 degrees, with a considerable range (0.2-3.1 degrees). The mean internal rotation of the hip decreased from 74 degrees to 53 degrees during the observation period, and the external rotation increased from 19 degrees to 37 degrees. While all 30 children had an intoeing gait at the first examination, this disappeared in all but 5 children.

“…- Rippstein (1955) found the same error in measurements of wire models. - Gross and haike (1970) checked their measurements (Rippstein's method) post mortem after dissection of the femora and found a maximum error of Such good results however can only be obtained, when the measurement is carried out with the upmost care for the details of the procedure, especially the correct positioning of the patient on the X-ray table. Dunlap et al (1953) and Gross and Haike (1 970) have analyzed the influence of potential errors in the procedure on the accuracy of the measurements; Positioning errors concerning rotation in the hip joints:…”
