Need for Distal Femoral Osteotomy
Femoral osteotomy is a highly convenient treatment for limb deformities in patients. Angular deformities can occur in the distal femur either in the developmental stages or through mal-alignment acquired later on. These are found in patients suffering from fracture malunion, osteoarthritis, metabolic disorders, adolescent-onset Blount disease or idiopathic processes (Seah et al. 2011). The axial alignment of lower limbs is affected by limb deformities, and is of immense concern when mechanical forces occurring during ambulation influence the articular cartilage. The varus and valgus alignment of the knee, when investigated through biomedical studies, have been shown to increase the medial and lateral load, thereby resulting in the progression of osteoarthritis.
Studies have shown that degenerative valgus deformities of the knee are less frequent than varus deformities (Wheeless 2012). In order to treat these deformities, the angle between the femur’s anatomical axis and the tibia’s mechanical axis has to be corrected up to 0-2° of valgus. This procedure will result in the unloading of the lateral tibio-femoral joint compartment, thus preventing the deformity from reoccurring. For the treatment of genu varum, high tibial osteotomy has been used successfully (Wheeless 2012). On the other hand, it is found to be less effective in case of genu valgum as it results in the formation of an oblique joint line. The tilting results in the generation of shear force across the knee, apart from lateral tibial subluxation, wherein the distal femur seems to fall off the plateau of the medial tibia. In such an instance, distal femoral osteotomy is apparently a better treatment option. Shoji and Insall (cited in Paddu et al. 2009), who studied 49 patients through a 31 month follow up, showed that only 26 of the 49 patients who had had proximal medial tibial closing wedge osteotomy had total relief from pain. Only seven of the patients had partial relief while sixteen had no relief at all. As already described, this treatment has been ineffective because when a major deformity in the valgus is corrected, the joint line slopes in the frontal plane superaolaterally. If the angle between the tibial mechanical axis and the anatomic femoral axis is more than 12-15° of the valgus, or if there is a deviation of the joint plane by more than 10° from the horizontal, distal femoral osteotomy is indicated. This specification was given by Bouillet and Van Gaver (cited in Paddu et al. 2009). A number of other studies have also suggested that osteotomy in the distal femur should be performed rather than in the proximal tibia if the angle between the tibia and femur is more than 12°. Another study by Maquet (cited in Paddu et al. 2009) has provided evidence that distal femoral osteotomy is a better treatment option for valgus deformity in patients as it helps in restoring the lower extremity’s mechanical axis, thereby reducing the Q angle and biomechanically altering the patellofemoral joint. Phillips and Krackow (1999) have suggested that this feature is an additional benefit as valgus malalignment is usually associated with patellofemoral disorders. In presence of restricted motion of the knee or inflammatory arthrititides, distal femoral osteotomy is contraindicated (Wheeless 2012; Distal Femoral Osteotomy 27450 2012).

Brief overview on the studies on the cardiac nervous system
In the 1950s, intrinsic cardiac ganglia were found primarily over the posterior surfaces of the atria and atrio-ventricular groove (Armour, Murphy, Yuan, MacDonald, & Hopkins, 1997). From then until now, the studies have evolved into defining their roles in heart function, the activities of the cardiac innervations at different conditions, the molecular mechanisms of their function, the diseases they are implicated in, and the effects of these discoveries in the management of cardiac diseases.

Myofascial Pain Patterns and Dysfunction of Lower Extremities Associated with Latissimus Dorsi Flap Breast Re-construction Proce
Even though this particular breast reconstruction technique is fairly safe, some of the postoperative breast cancer patients who had mastectomy and LD flap breast reconstruction are complaining about myofascial pain and lower extremities dysfunction. Up to the present time, there is no existing research study that has tried to discuss and identify the main factors that causes myofascial pain and lower extremities dysfunction after going through LD flap breast reconstruction.

Any imbalance in beating pattern is caused by Sino- Atrial node, situated in the right atrium. Paroxysmal atrial fibrillation is caused due to diversity of acute disorders and WPW syndrome. It could also result from digoxin toxicity. Atrial fibrillation could be classified to silent atrial fibrillation, atrial fibrillation in the setting of failure of heart and atrial fibrillation within the setting of myocardial infarction.
