This study was aimed to look into factors responsible for delayed mobilization after lower limb arthroplasty and effect on length of stay. It is an observational study conducted at Kings Mill Hospital from August to October 2021. All patients undergoing primary knee or hip arthroplasty were included in the study, while patients with revision surgeries were excluded. A proforma was designed to record demographics and different variables including medications, type of anaesthesia, orthostatic hypotension, dizziness, preop and post op pain score, fall in haemoglobin, analgesia and length of stay. Patients were assessed on day one and data was recorded in the proforma. Data was analysed using SPSS.Abstract

Methods
The aim of our study was to assess the outcome of caudal epidural injection for patients with low back pain in relation to fatty infiltration of spinal muscle. This is a prospective study. The spinal muscles were graded on sagittal section T1 MRI at the lower border of lumber 4 vertebra from 3 to 12 depending on the severity of fatty infiltration. The outcome of the intervention was assessed by improvement in pre and post intervention oswestry disability index score as well as visual analog pain score. Patients with significant fatty changes don't respond well to the caudal epidural injection.
The quality of femoral stem cementation has been shown to be a useful indicator of long-term survival of the total hip arthroplasty. Barrack's cementation grading is widely used but has certain limitations. It is based upon second-generation cementation technique and has high inter- and intra-observer variability. We introduce a new femoral cementation index based upon lengths of radiological lucency and cement-bone interface on AP and lateral views. Five observers graded femoral cementation of radiographs of 30 primary hip arthroplasties using Barrack's grading and the new index on two occasions and Inter- & Intra-observer reliability was assessed. We also assessed the correlation between proximal femoral anatomy (calcar-canal ratio) & structural bone quality (using cortical index) with cementation using the new index in 50 patients. Inter- and intra-observer reliability of the new index showed intraclass correlation coefficient 0.79 and 0.82 respectively and Barrack's grading system showed Kappa value- 0.20 (inter-observer) and 0.55 (intra-observer) reliability. There was poor correlation between the calcar-canal ratio and the quality of cementation [Pearson's coefficient −0.04 (p< 0.05)]. There was some correlation between the cortical index and the quality of cementation [Pearson's coefficient 0.46 (p < 0.05)]. Our new index is a reliable method of assessing femoral cementation. The anatomy of femoral canal didn't have any significant influence on the quality of cementation achieved as assessed by our new index. The femoral cortical structural quality seemed to have some positive influence on the quality of cementation.
