“…Each part has unique importance and contribution, the loss or change of a component can result into important or small alterations. The only way to understand them is analyzing how each component is distributed in the individual (4) , as well as the importance to understand the biomechanical alterations that each clinical problems cause in the locomotor parts (1,3,6,8,11) .…”

SUMMARYVariations and deformities of lower limbs involving rotation in the transverse plane are associated with many clinical problems, ranging from harmless in-toing in children to disabling degenerative osteoarthritis of the knee in adult patients.While the bone alterations located in the transverse plane are difficult to be assessed, the frontal and sagittal deformities can be easily assessed , for instance, with the conventional radiographies.In this context, among the most available methods for the leg rotational study, there is not any clinical or image procedure which is more accurate, practical or with low cost.In order to solve this problem, the authors present a new device to indirect clinical standard of the leg torsion angle in adults and children. In this study, 40 lower limbs from human cadavers were assessed and analyzed.

PurposeThe aim of this systematic review was to identify the surgical indications of tibial derotational osteotomy (TDO) in patients with idiopathic external tibial torsion (ETT) and identify common measurement thresholds for surgical correction.MethodsA systematic search of MEDLINE and Embase via Ovid, Cochrane Library via Wiley, Web of Science, Scopus, SPORTDiscus via EBSCOhost, ClinicalTrials.gov, WHO ICTRP and Global Index Medicus databases was performed with search terms reflecting the concepts of idiopathic tibial torsion, TDOs, and surgical indications. Studies reporting surgical indications and measurement methods of idiopathic tibial torsion in patients who underwent TDO were included. Two authors independently screened articles and extracted data that was characterized with descriptive statistics.ResultsSeventeen studies were identified for inclusion, with 460 tibias and 351 patients. Nearly all patients who underwent surgery had either anterior knee pain or patellar instability, even if other indications were present. Of all included patients, the most common surgical indications for TDO were anterior knee pain (88%), patellar instability (59%), gait dysfunction (41%) and cosmetic deformity (12%). Twelve studies (71%) cited multiple of these indications as reasons for surgery. On physical exam, tibial torsion was measured most commonly by thigh–foot angle (59%) (TFA) and transmalleolar axis (24%) (TMA). In terms of TFA, the most frequently reported cut‐off for ETT was >30° (35%). Computerized tomography (CT) was used by nine studies (53%). The most common CT axes used to measure ETT were the TMA with respect to the posterior tibia condylar axis or the bicondylar tibia axis.ConclusionAnterior knee pain and/or patellar instability are common indications for TDO in patients with idiopathic tibial torsion. Standardized TFA thresholds (>30°) and CT measurement methods (TMA and posterior tibia condylar or bicondylar tibial axis) may help further establish objective surgical indications.Level of EvidenceIV.
