Aim: We aimed to conduct a study comparing early outcomes of bilateral total knee replacement (BTKR) done in single sitting versus double sitting. Materials and Methods: The study included 58 patients who were already operated case of BTKR done in single sitting (sequential BTKR) – Group I (n = 30) and double sitting (staged BTKR) – Group II (n = 27), during time period April 2016 to May 2019. At follow-up, functional outcome in both the groups was assessed by Knee Injury and Osteoarthritis (OA) Outcome Score, Western Ontario and McMaster Universities OA Index score, and Visual Analog Scale scores. Results: The mean age in Group I was 64.5 ± 10.52 years and in Group II was 63.92 ± 5.76 years. The mean body mass index (BMI) in Group I was 28.42 ± 1.365 kg/m2, whereas the mean BMI in Group II was 29.19 ± 1.898 kg/m2. The mean length of hospital stay in Group I was 15.23 ± 2.921 days as compared to 23.69 ± 5.259 days in Group II. There was no mortality in both the groups within 90 days after operation in both the groups. There was significantly less requirement of hospital stay in Group I as compared to Group II (P = 0.001, Mann–Whitney U-test). Conclusion: We found that the single sitting BTKR is cost-effective and a relatively safe surgery. There was significantly lower length of hospital stay in single sitting BTKR along with no major complication in our study. Thus we advocate BTKR as a single sitting surgery with proper patient selection and preanesthetic workup.

Background: India is a home for 27% of the world's tuberculosis (TB) cases. When compared, extrapulmonary TB (EPTB) cases have a lower incidence than pulmonary TB (PTB), but there is no significant reduction in the incidence of EPTB than PTB. Spinal TB is most common of skeletal TB. Aims: We aimed to study and to identify the clinical-radiological features in spinal TB and the incidence of neurological involvement along with factors associated with it. Settings and Design: This was a retrospective study in a tertiary care center of Central India. Subjects and Methods: A total of 114 cases with spinal TB were included in the study. Data collected retrospectively from January 2008 to December 2018 using a picture archiving and picture archiving and communication system of the hospital. Radiographs, magnetic resonance imaging scan, computed tomography, and ultrasound findings were studied. History and clinical examination findings were thoroughly analyzed. Statistical Analysis Used: Data were analyzed using Epi Info Software. Results: There were 74 (64.9%) male cases and 40 (35.1%) female cases. Most of the cases belong to rural 85 (74.5%) than urban 29 (24.5%) area. After neurological evaluation, paraparesis/paraplegia was observed in 52 (45.6%) cases and tetraplegia in 2 (1.7%) cases. Sensory deficit was observed in 10 (10.5%) cases. Bowel/bladder involvement was present in 5 (4.4% cases). Most of the cases with neurodeficit had dorsal vertebral involvement 30 (61.1%). Conclusions: The pattern of spinal TB is varied and is difficult to get diagnosed. We observed a high proportion of cases with neurodeficit. Most of them were with late-onset TB. This highlights that early diagnosis and complete treatment are very important in the treatment of TB of the spine.

Ipsilateral fractures of the femur and tibia have been called “floating knee” injuries and may include combinations of diaphyseal, metaphyseal, and intra-articular fractures. These are often high-energy injuries and most frequently occur in the polytrauma patient. Many of these fractures are open, with associated vascular injuries. Surgical stabilization of both fractures and early mobilization of the patient and the extremity produce the best clinical outcomes. This rare case report is of 43-year-old female from an urban setup in Chennai who underwent an Road Traffic Accident (RTA) and sustained injuries that lead to a bilateral floating knee. She was initially managed as per principles of damage control orthopedics and stabilized with knee spanning external fixators on either side. On further stabilization of the patient, bilateral definitive fixation was done in a staged manner. The patient finally regained full functional range of motions on either limb and was completely rehabilitated within 3 months.

Introduction: Osteoporosis is a common metabolic disease of the bone characterized by decreased bone mass and micro-architectural deterioration in bone tissues that results in increased susceptibility to fractures. Osteoporosis is a significant public health problem in many parts of the world, also in India. The primary purpose of the article is to find out the prevalence of osteoporosis in Eastern Odisha through the cross-sectional study of bone mineral density (BMD). Materials and Methods: Two thousand and one hundred individuals within the age range of 20–82 years were included in the study. It was conducted between February 2016 and August 2017. The instrument to measure BMD was the Achilles Express Bone Ultradensitometer. Their average BMD was calculated according to T score by using the World Health Organization guidelines for the classification into normal, osteopenic, and osteoporotic. The findings were statistically analyzed. The results were compared with the results of other authors. Statistical analysis was performed using the SPSS software version 16 (IBM Corporation, Armonk, New York USA). Results: Prevalence of osteoporosis was found to be 22.4% and osteopenia 37.9%. There was a significant difference in the prevalence of osteoporosis between premenopausal and postmenopausal women. Conclusion: In India, no centralized data are available to show the prevalence of osteoporosis. This study was an effort to find out the prevalence of osteoporosis in Eastern part of Odisha, India. Ultrasonic heel densitometry is a safe and noninvasive method for the assessment of BMD to diagnose and assess the osteoporotic individuals so that adequate steps can be taken in them to prevent fracture and other complications of osteoporosis.
骨质疏松症是一种常见的骨代谢性疾病，其特征是骨量减少，骨组织微结构恶化，导致骨折易感性增加。骨质疏松症在世界许多地区是一个重大的公共卫生问题，在印度也是如此。本文的主要目的是通过骨密度(BMD)的横断面研究来了解奥里萨邦东部骨质疏松症的患病率。材料与方法:研究纳入年龄在20-82岁之间的2,100名个体。该调查于2016年2月至2017年8月进行。测量骨密度的仪器为阿基里斯快速骨超强度计。他们的平均骨密度是根据T评分计算的，按照世界卫生组织的指南分为正常、骨质减少和骨质疏松。对调查结果进行统计分析。结果与其他作者的结果进行了比较。采用SPSS软件16版(IBM Corporation, Armonk, New York USA)进行统计分析。结果:骨质疏松率为22.4%，骨质减少率为37.9%。绝经前和绝经后妇女的骨质疏松患病率有显著差异。结论:在印度，没有集中的数据显示骨质疏松症的患病率。本研究旨在了解印度奥里萨邦东部地区骨质疏松症的患病率。超声足跟密度测量是一种安全、无创的评估骨密度的方法，用于诊断和评估骨质疏松症患者，以便采取适当的措施预防骨折和骨质疏松症的其他并发症。

Background: Intertrochanteric fracture is one of the most common fractures of the hip, especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. This study was done to compare the functional and radiological outcome of PFN with dynamic hip screw (DHS) in treatment of type 31-A2, intertrochanteric fractures. Materials and Methods: From June 2019 to June 2021, prospective randomized and comparative study was conducted on the 162 patients of type 31-A2 intertrochanteric fractures of hip who were operated using PFN or DHS. Intraoperative complications were noted. Functional outcome was assessed using Harris hip score (HHS) and radiological findings were compared at 6, 12, and 24 months postoperatively. Results: In our study, out of 162 patients, 77 patients are managed with DHS, while 85 patients are managed with PFN. The average age group of the patients was 61–70 years. In our series, we found that patients with DHS had longer duration of surgery (111 min) and required longer time for mobilization, while patients who underwent PFN had shorter duration of surgery (97 min) and allowed early mobilization. In addition, complications such as DVT, lag screw cutout, shortening, and superficial infection are more in DHS group as compared to PFN group. The patients treated with PFN started early ambulation as they had better HHS in the early postoperative period as well as late postoperative period. Conclusion: PFN is better than DHS in type 31-A2 intertrochanteric fractures in terms of decreased blood loss, reduced duration of surgery, early weight-bearing and mobilization, reduced hospital stay, decreased risk of infection, and decreased complications.

Introduction: Biceps tendon degeneration or tearing is a significant cause of shoulder discomfort and dysfunction. Biceps tenodesis is commonly performed to treat symptomatic biceps tendon pathology. A variety of fixation techniques can be used including screw fixation, endobutton, or suture anchor techniques. This study examines the patient outcomes when the FOOTPRINT™ Ultra suture anchor system is used for biceps tenodesis. Materials and Methods: Retrospective review of consecutive patients undergoing biceps tenodesis was conducted. All patients underwent biceps tenodesis using the FOOTPRINT™ Ultra suture anchor. The primary endpoint was any device-related complication during the intraoperative or postoperative period. Descriptive and inferential statistics were performed to assess patient characteristics and outcomes. Results: Twenty-nine patients were included in this study; 20 (69.0%) underwent arthroscopic biceps tenodesis and the remainder underwent open surgery. The mean follow-up time was 8.51 ± 5.28 months postoperatively. One patient experienced a postoperative infection within the first 30 days requiring a return to the operating room. Two patients experienced a complication within the first 6 months postoperatively. No patients experienced a device-related complication. No patients experienced a retear of their biceps tendon; two patients experienced a retear to their rotator cuff repair. The mean pain Numeric Rating Scale improved from 5.88 ± 2.58 on a scale of 0–10 preoperatively to 1.94 ± 2.32 postoperatively (P < 0.001). Conclusion: The FOOTPRINT™ Ultra suture anchor appears to be safe for the use in patients undergoing arthroscopic or open biceps tenodesis.

Introduction: The aim of this study was to research factors affecting the short-term outcome of metal-on-metal hip resurfacing (MOMHR) and develop a multivariate regression model that may predict outcome. Materials and Methods: This was a prospective study of 154 patients who underwent MOMHR and were followed for a minimum of 1 year. Fourteen independent variables (age, gender, diagnosis, co-morbidities, body mass index (BMI), pr-operative Western Ontario and McMaster Universities Osteoarthritis (WOMAC) physical component/stiffness (S)/pain (P), short form 12 (SF-12) physical (SP), SF-12 mental (SM), acetabular and femoral component sizes, operative time, and estimated blood loss) were analyzed using correlation and multivariate regression analyses. Multivariate regression model was tested by using an independent cohort for validation. Results: Correlation analyses found four variables that significantly influence short term MOMHR outcome. These include comorbidities (C, P = 0.0001), preoperative SF-12 mental (SM, P = 0.0004), BMI (P = 0.0006), and gender (G, P = 0.0454). By multivariate analysis, the subsequent regression model was obtained with an R2 value of 0.3816: Outcome = G*4.72 ‒ BMI*0.70 ‒ C*0.11 + SM*0.31 + 87.44. The average predicted outcome using this equation did not differ significantly from the observed WOMAC physical function outcome at a minimum of 1 year postoperatively. Conclusion: To the best of our knowledge, this study is the first reported multivariate analysis of factors affecting MOMHR and confirms the correlation of some of the previously proposed factors such as gender, BMI, comorbidities, and preoperative function. The multivariate regression equation can be used to predict the short-term outcome of MOMHR.
本研究的目的是研究影响金属对金属髋关节表面置换(MOMHR)短期预后的因素，并建立一个可能预测预后的多元回归模型。材料和方法:这是一项前瞻性研究，154例患者接受了MOMHR，随访至少1年。14个独立变量(年龄、性别、诊断、合并症、体重指数(BMI)、手术前西安大略和麦克马斯特大学骨关节炎(WOMAC)物理成分/僵硬度(S)/疼痛(P)、短形式12 (SF-12)物理(SP)、SF-12精神(SM)、髋臼和股骨成分大小、手术时间和估计失血量)采用相关和多变量回归分析进行分析。采用独立队列对多元回归模型进行验证。结果:相关分析发现四个变量显著影响短期MOMHR结果。这些包括合并症(C, P = 0.0001)，术前SF-12精神(SM, P = 0.0004)， BMI (P = 0.0006)和性别(G, P = 0.0454)。经多因素分析，得到后续回归模型，R2值为0.3816:Outcome = G*4.72 - BMI*0.70 - C*0.11 + SM*0.31 + 87.44。使用该方程的平均预测结果与术后至少1年观察到的WOMAC身体功能结果没有显著差异。结论:据我们所知，本研究首次报道了影响MOMHR因素的多变量分析，并证实了先前提出的一些因素(如性别、BMI、合并症和术前功能)之间的相关性。多元回归方程可用于预测MOMHR的短期预后。
