BACKGROUND This study was conducted to examine the recovery times following cemented or uncemented total hip arthroplasty for patients with avascular necrosis of the femoral head and to examine the clinical and functional outcomes of cemented versus uncemented total hip replacements in patients with this agonizing condition. METHODS This was a 17-month study that took place in a hospital setting and involved 30 patients with hip joint arthritis brought on by avascular necrosis of the femoral head. The patients gave written informed consent and the approval of the institutional ethics committee before being referred to the Department of Orthopedics at the Princes Esra Hospital/Deccan College of Medical Sciences, Hyderabad, Telangana, India. RESULTS Before surgery, the mean functional gait score was 10.53±6.96, and after surgery, it was 30.33±2.31. Prior to surgery, the functional activity score was 5.17±1.62, and following surgery, it was 11.40±1.07. The study group's preoperative and postoperative scores showed statistically significant variation. The average Harris hip score was 32.27±8.11 before surgery and 92.60±3.16 after surgery. The differences in scores before and after surgery were statistically significant. Before surgery, the study group's mean ROM score was 2.40±1.25, and after surgery, it was 4.63±0.49. In the preoperative and postoperative phases, there was a statistically significant difference in ROM evaluations. CONCLUSION The current generation of uncemented implants used in total hip replacement for AVNcaused hip arthritis yields, satisfactory clinical and radiological outcomes after a reasonable period of follow-up. Despite a few problems with the course of treatment, functional and clinical outcomes have been good to exceptional overall. [ABSTRACT FROM AUTHOR]

Background: Bipolar hemiarthroplasty is the standard of care for transcervical fracture in the elderly. Stainless steel being cheaper is preferred over titanium in developing nations for implants and prostheses. This study was conducted for assessing the short-term outcomes of uncemented bipolar hemiarthroplasty done using hydroxyapatite-coated stainless steel prosthesis. Methods: Sixty-five patients, >60 year of age operated between 2018 and 2020 at tertiary care centre with stainless steel (316L) completely coated with hydroxyapatite bipolar hemiarthroplasty implants were retrospectively followed up. Radiological outcomes were assessed based on pedestal formation, stem position, radiological limb length discrepancy, sinkage of stem, spot welds and stress shielding. Clinical and functional outcomes were assessed based on mean Harris Hip score. Results: Mean Harris Hip score at baseline, 3-week follow-up, 6-week follow-up, 3-month follow-up and 1-year follow-up was 45.9 (SD 2.5), 63.2 (SD 6.5), 75.1 (SD 9.9), 83.9 (SD 9.8) and 87.1 (SD 9.9), respectively. Excellent, good, fair, poor results were seen in 32.31, 40, 18.46, 9.23 of the patients, respectively. Valgus, central and varus stem position was seen in 49.23, 40, 10.77 percent of the patients, respectively. Pedestal formation, radiological limb length discrepancy, sinkage, spot welds, stress shielding was seen in 6.15, 32.31, 3.07, 53.85, 40 percent of the patients, respectively. Conclusion: Short-term outcomes of this study provides evidence that using a more affordable fully hydroxyapatite-coated stainless steel prosthesis for uncemented bipolar hemiarthroplasty is an appropriate treatment option for the transcervical femur fracture.

To assess the functional outcomes of the unstable intertrochanteric fractures in the osteoporotic individuals treated by primary cemented hemiarthroplasty by early mobilization and immediate weight-bearing, restoration of limb length, and gait Assessment. It is a prospective study of 17 elderly patients with comminuted intertrochanteric fractures managed with cemented hemiarthroplasty attending to the Department of Orthopaedics, Government General Hospital, Rangaraya medical college, Kakinada. 17 cases of unstable intertrochanteric fractures were treated with cemented bipolar hemiarthroplasty. The average follow-up period was 12 months. The average age was 72.75 years with a standard deviation of 5.56. Most (82.3%) of the patients presented with Boyd and Griffin type 2 fracture. The functional assessment by HHS showed good to excellent outcomes in most of the patients (64.7%). 2 patients had abductor weakness, 1 patient had superficial surgical site infection, one had hypotension, and 1 patient had bedsore. Primary cemented bipolar prosthetic replacement in comminuted intertrochanteric fractures in the elderly patients provide s painless, stable, and mobile hip joint so that we can institute early postoperative mobilization which can avoid the consequences of prolonged recumbency. Hemiarthroplasty also avoids a second procedure in such elderly patients with multiple comorbidities as there is a high risk of failure of internal fixation in patients with poor bone quality, subjecting them to a second surgery and anaesthesia being a risky proposition.

Background: Objective of the study was to evaluate and compare psychometric properties such as validity, reliability, floor ceiling effects and interpretability of the modified Harris Hip Score (mHHS) and the Forgotten Joint Score (FJS) in patients undergoing bipolar hemiarthroplasty for femoral neck fracture in Indian patients, because this has not been done before. Methods: This observational study consisted of 40 consecutively operated patients. Construct validity and reliability were evaluated using correlation coefficient and Intraclass correlation coefficient (ICC), respectively. Interpretability was evaluated by describing mean and standard deviation of mHHS and FJS in five subgroups of patients based on their response to the global rating questions and assessment. Results: The mean follow-up duration was 15.7 months ± 10.4. There was very high correlation between mHHS and FJS (r = 0.92, p < 0.0001) suggesting convergent construct validity. The results of correlation coefficient were 100% and 66.7% in accordance with the pre-formulated hypotheses for mHHS and FJS, respectively. mHHS and FJS demonstrated adequate construct validity and inadequate construct validity, respectively. The ICC value for mHHS and FJS was 0.80 (p = 0.005) {adequate reliability} and 0.34 (p = 0.06) {inadequate reliability}, respectively. Both mHHS and FJS-12 demonstrated acceptable level of floor (0% for mHHS and 14.3% for FJS) and ceiling effects (12.5% for both mHHS and FJS). There was significant difference in the mHHS and FJS in the five subgroups of patients suggesting adequate interpretability. Conclusion: We recommend the use of the modified Harris Hip Score over the Forgotten Joint Score for functional outcome evaluation of Indian patients from rural setting undergoing bipolar hemiarthroplasty for femoral neck fracture.

There are several reports in medical literature about Red Cell Exchange (RCE) being routinely performed pre-operatively in sickle cell disease patients to provide immediate decrease in HbS concentration and prevent post-operative complications. We would like to present one such case of SCD who also had multiple allo-antibodies and had to undergo hemi-arthroplasty for avascular necrosis of head femur. Grouping and antibody screening was performed using column agglutination technique. 3-cell and 11- cell panel were used for antibody screening and identification, respectively. Automated RBC exchange was performed on apheresis machine Com.Tec using the standard PL1 kit (Fresenius Kabi, Germany). Multiple (anti-c, E) allo-antibodies were identified and successful pre-operative RCE was done with corresponding antigen-negative AHG compatible RBC units. Single RCE procedure reduced HbS concentration from 65% to 25%. The patient underwent uneventful hemi-arthroplasty and was discharged on post-operative day-7. Patient is on regular follow-up and continues to do well two months after the day of surgery. This is possibly the first case report from India, which illustrates successful automated RCE in a SCD patient with alloimmunization. [ABSTRACT FROM AUTHOR]
