Obesity remains the most important risk factor for the incidence and progression of osteoarthritis (OA). The leading cause of OA was believed to be overloading the joints due to excess weight which in turn leads to the destruction of articular cartilage. However, recent studies have proved otherwise, various other factors like adipose deposition, insulin resistance, and especially the improper coordination of innate and adaptive immune responses may lead to the initiation and progression of obesity-associated OA. It is becoming increasingly evident that multiple inflammatory cells are recruited into the synovial joint that serves an important role in pathological changes in the synovial joint. Polarization of macrophages and macrophage-produced mediators are extensively studied and linked to the inflammatory and destructive responses in the OA synovium and cartilage. However, the role of other major innate immune cells such as neutrophils, eosinophils, and dendritic cells in the pathogenesis of OA has not been fully evaluated. Although cells of the adaptive immune system contribute to the pathogenesis of obesity-induced OA is still under exploration, a quantity of literature indicates OA synovium has an enriched population of T cells and B cells compared with healthy control. The interplay between a variety of immune cells and other cells that reside in the articular joints may constitute a vicious cycle, leading to pathological changes of the articular joint in obese individuals. This review addresses obesity and the role of all the immune cells that are involved in OA and summarised animal studies and human trials and knowledge gaps between the studies have been highlighted. The review also touches base on the interventions currently in clinical trials, different stages of the testing, and their shortcomings are also discussed to understand the future direction which could help in understanding the multifactorial aspects of OA where inflammation has a significant function.

Introduction: As a result of increasing longevity, we are seeing more elderly patients with complex medical co-morbidities who sustain hip fractures requiring surgical management. The aim of this study is to understand and analyze the effect of preoperative medical comorbidities and associated low physiological reserve status on functional rehabilitation outcomes following surgical management of hip fractures. Materials and methods: This study conducted a retrospective analysis of 73 patients who fulfilled the inclusion criteria .We utilized the de Morton Mobility Index (DEMMI) scores pre surgery and at the time of discharge from hospital following a period of rehabilitation as a measure of their pre and post-surgery functional status. The Physiological and Operative Score (POSSUM) was used as our tool to objectively quantify medical co-morbidities including but not limited to cardiovascular and pulmonary conditions. Results: The median age of our study population was 83 years of which 55(75%) were female. Time to surgery was a median of 21.0 hours, IQR (15.0-29.0), with a median physiological score of 21.0, IQR (19.0-26.0), the median pre surgery DEMMI was 85.0, IQR (55.5- 100.0) and the median DEMMI at discharge was 33.0, IQR (30.0-41.0).There is a moderate correlation between DEMMI pre and DEMMI at 3 months, 0.38 that is statistically significant, p = 0.001. Discussion: The effect of medical co- morbidities which causes the patient to have a poor physiological reserve even when coupled with the effect of the operative stress have no significant negative impact on the 90-day functional outcome of these patients. Conclusion: This study demonstrated that the presence of medical comorbidities in patients who require surgical management of hip fractures would not adversely affect their rehabilitation outcomes. The preinjury functional status of a patient is a significant factor in predicting functional rehabilitation outcomes.

We report a case of scoliosis, fracture of the neck of the femur and ochronosis occurring together in a patient.

Airway management is considered one of the most difficult and challenging procedures among the various anesthetic procedures. It becomes tougher when there is a diseased temporomandibular joint (TMJ) due to inadequate mouth opening. In the current scenario there are only a few methods that ensure a safe, uneventful intubation in a TMJ ankylosis patient with a difficult airway. These include techniques ranging from minimally invasive techniques like blind nasal intubation, retrograde intubation using a guide wire, the latest technique of intubating with the help of a fiberoptic laryngoscope and the time tested tracheostomy. All these techniques have got their own disadvantages. So we report a case series of five patients with TMJ ankylosis who underwent fluoroscopic-assisted intubation for airway management. We found that this technique is 100% successful in managing the airway in these patients. To the best of our knowledge, this is the first case series detailing this novel technique in the entire English medical literature.
