He described three variations that included excision of a medial based wedge with its reversal to obtain "varusation and containment" with anterior head containment by derotation
. In the cases in which he was unable to achieve the desired degree of medial rotation of the proximal fragment, an excision of a posterior based wedge to obtain head containment by extension was performed.
He had surgery in 2012 that included lengthening multiple muscles and bone derotation
of the tibia/fibula.
Because of lateral expansion and derotation
in pos- terior segment, some amount of mesial movement of molars could also have occurred, to improve molar relation.

PDH can be repaired by reduction of hernia contents and excision of the hernia sac, with or without intestinal derotation
, thereby avoiding injury to the major mesenteric vessels juxtaposed to the hernial orifice.
In addition to potential QAM symbol estimation error induced by received [mathematical expression not reproducible] deviation, there are two other receiver processes that are key for achieving reliable QAM symbol estimation, including (1) received carrier frequency offset [f.sub.Rx] estimation and (2) phase recovery for symbol constellation derotation
Tooth movements like derotation
and torquing are also difficult in these teeth because of their imbalanced shapes and unusually broad mesiodistal root surface areas.7 Such anomaly may also be a cause of malocclusion as additional space is required for a tooth to be accommodated in dental arch.8
However, it lacks axial distraction forces and cannot perform derotation
. In 1984, Cotrel and Dubousset introduced their segmental fixation system, known as the CD system, which was considered as the first 3D internal fixation system.
In our study of subtrochanteric fractures treated with PFN, we encountered intraoperative complications like iatrogenic fracture of lateral cortex in 2 cases (10%) due to selection of wrong entry point, failure to put derotation
screw in 2 cases (10%) and guidewire breakage in 1 case (5%).
Despite reports stating that tibiotarsal rotation cannot be treated successfully with surgery, (8) our results demonstrated that rotation treatment is possible by creating a closed fracture and fixing the fracture after derotation
. This technique was used successfully in 19 birds in our study.
