Introduction: Hip resurfacing arthroplasty (HRA) or Total hip replacement (THR), as it is popularly called, attempts to mollify these basic clinical problems, in patients with a hip arthritic problem, which may be of a sequela to age-related degeneration, osteonecrosis, systemic disorder like Rheumatoid arthritis (RA) or Ankylosing spondylosis (AS) or as a result of trauma and or an old infection. The basic pathology, is an unfavourable and abrading hip diarthrodial joint. The endeavour of the study was, to establish the efcacy of the Posterior vs Lateral approach for THA/THR, by studying their outcomes in primary THR. This prospective study was undertaken at Che Materials And Methods: ttinad Hospital and Research Institute (CARE), Kelambakkam, Chengalpattu district, Tamilnadu, In the Department of Orthopaedics from Jan 2017 to Dec 2020 (48 months). The Functional outcome of hip surgery was measured using the Harris Hip Score, Oxford hip score and the WOMAC. Rivermead visual gait analysis (RVGA) method was used post-operatively to assess the gait. The Biomechanical outcomes of Abductor Gait Component, were individually assessed by EMG studies. The Harris Hip Score, The Oxford Hip S Results: core and WOMAC score, when the lateral approach was compared to the posterior approach pre-op and post-op in the 12 months minimum follow-up period, the laterally approached group faired better. The VAS score was equivocal. The comprehensive RVGA assessment also showed marginally better results for the laterally approached group as was the case with the Trendelenburg test score. The EMG studies for the Gluteus Maximus, Medius and the lateral rotators of hip also favoured the outcomes for the laterally approach hips. The supremacy of the Lateral Approach, ove Conclusion: r Posterior Approach, cannot be adjudged in a short-term follow-up study. It is thus opined that the Lateral Approach may be statistically and data wise superior, but the patient satisfaction, which is a major factor, is almost the same in both the approach groups. The follow-up needs to be atleast for a decade for us to be able to come to any meaningful conclusion. With regards to surgery like the Total hip replacement, which have a longevity factor exceeding 10 years, studies have to be followed up for periods in excess of 10 years.

Trochanteric fracture id one of the commonest fractures in Orthopaedics and also among the most devastating injuries of the elderly. The incidence of this fracture increases with advancing age. Around 50% of the Peri-trochanteric variant of these fractures, are of the unstable type. PFNA2 deploys a helical blade which provides compressibility and an additional rotation control at the fracture site.The aim of this study is to assess the effectiveness of Intra-medullary xation of unstable peri-trochanteric fractures with inter-locking proximal femoral nail PFNA2, in a prospective study. This study was done in Department of Orthopaedics, Chettinad Hospital and Research institute, Kelambakkam, Chengalpattu district, Tamilnadu and was spread over 4 years from Jan 2017 to December 2020 with minimum follow-up period of 12 months. 66 patients participated in this study. Harris Hip Score was used to assess the functional outcome. The Harris Hip Score, mean at 6 months was 75.35, which improved to 82.02 by 12 months of follow-up. With regard to our complications 4 patients had a superior cut out of helical screw, which required re-operation by bipolar hemiarthroplasty of the cemented variant. 9 patients had a varus deformity of 10-12 degrees. Abductor lurch was noted in 11 patients. Supercial-wound infection occurred in 8 patients and deep wound infection, requiring surgical irrigation occurred in 3 patients. In conclusion, PFNA2 has better stability, better rotatory stress shielding, superior compaction at fracture site, less blood loss, shorter operation time, less radiation exposure and better clinico-radiological outcomes. PFNA2 is a good implant choice to tackle the complex problems encountered in displaced unstable trochanteric fractures

Mobile phones have become a crucial requirement in the modern day world. They have emerged as the most common and straightforward means of global communication and information access. Setting the appropriate pricing range for mobile phones is crucial. To determine pricing, all of their features must be considered. This study paper's major goal is to achieve mobile pricing. In this paper we have used different machine learning algorithms along with ensemble algrithms and made a study between Gradient Boosting and Artificial Neural Networks(ANN’s) to find which suits best for our data. We got an accuracy of 91.25% for MLP classifier. An interactive web sites employing flask is also designed to make customers easier to choose a price range.
