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.

Aim: The aim of this study is to evaluate the efcacy of vertebroplasty for treatment of painful osteoporotic vertebral fractures on clinical grounds. Materials & Methods: 20 patients with osteoporotic compression fractures treated by vertebroplasty were enrolled in this study. In all patients, Pre operative Visual analog score for back ache, Oswestry disability score were noted for the purpose of comparison of post operative functional outcome. In our study, average follow up was done for 12 months with maximum follow up wa Observation & Results: s for 16 months and minimum follow up was for 3 months. Statistics comparing preop VAS score versus VAS score, pre op ODS vs post op ODS at immediate, one month, three months, six months and twelve months were done from which we interpreted that p value <0.005 in all postoperative period, so it was a signicant comparison. Statistically, there was signicant pain relief and functional outcome in immediate post operative period which was maintained at the end of 12 months also. We conclude that the Vertebroplasty Conclusion: are promising innovations with the benet of quick improvement in mobility, markedly decreases pain-related doctor visits, stature in the management of osteoporotic compression fracture
