The goal of this approach is to recreate an anatomic alignment of the new joint line with approximately 2[degrees] to 3[degrees] of joint line
varus relative to the perpendicular mechanical axis of the tibia.
The most common type of angulation was
varus angulation.
Several complications are also described related to intramedullary implants, including malalignment, cut-out, infection, false drilling, wrong lag screw length and drill bit breakage during the interlocking procedure, external or internal malrotation ([less than or equal to]20[degrees]) of the femoral diaphysis, elongation of the femur (up to 2 cm), impaired bone healing, periprosthetic fracture distal to the tip of the nail, fracture collapse, implant failure, lag screw intrapelvic migration, neurovascular injury, secondary
varus deviation, complications after implant removal, trochanteric pain, and refracture (17).
Production of normal arch was necessary to correct the adductus and the
varus. The foot was manipulated and heel was not touched to allow the calcaneus to abduct the foot.
It was hypothesized that 1) participants with a
varus alignment will have a greater KAM compared to participants with a neutral or valgus alignment, and 2) KAM will not differ regardless usage of a toe clip.
All patients had mild
varus deformities, which was 7.7 [+ or -] 3.5[degrees] in average.
The development of reconstruction nail designs allows for additional fixation via forces between the cephalomedullary screw and the femoral neck and head preventing
varus and flexion deformities [21].
Physical examination showed pain, an evident
varus deformity, chair sign positive, and clear pivot shift.
For example, providing medial calcaneal mobilizations/releases for the overpronator would be great if the patient has a compensated calcaneal
varus. But ifthe patient has a compensated forefoot
varus the medial mobilization/release would likely worsen their injury.
applied curved intertrochanteric
varus osteotomy to 53 hips with the diagnosis of femoral head osteonecrosis and reported successful clinical results in a mean follow-up of 6.2 years (17).
Its management is difficult due to instability of fracture pattern with a tendency to
varus collapse and the muscular forces acting on the fractured fragments resulting in shaft medialization.
Laxity and
varus deviation of the distal left hindlimb at the intertarsal joint were first observed 2 years prior to presentation at the animal's previous institution.
