This document presents three cases of articular fractures and discusses the management of such fractures. The key points are:
1) Articular fractures require anatomic reduction, stable fixation to allow for early mobilization in order to preserve the articular cartilage. Loss of reduction or immobilization can lead to joint stiffness and osteoarthritis.
2) Early mobilization is important to prevent joint stiffness and ensure proper healing, as articular cartilage relies on motion and load bearing for nutrition from synovial fluid.
3) Management of articular fractures involves open reduction, anatomic restoration of the articular surface, stable fixation through methods like lag screws or plates to achieve "absolute stability", and early range of motion exercises

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

• Inability to bear weight
3. Examination
L/E of Left Knee:
• Overlying Skin: Intact
• Swelling ++
• Tenderness + over anterior aspect of left knee and leg
• DNVS : Intact
• ROM : Couldn’t be elicited
7. Management
In ER ,
◦ Limb was immobilized

◦ Close monitoring of neurovascular status/ development of compartment syndrome
•Baseline blood investigations were sent and patient was planned for surgery
8. Surgery
•Operated on 6th day after swelling subsided
•ORIF with Bicolumnar plating was done via
Anterolateral and Posteromedial approach
•Articular congruency was maintained and
corticocancellous bone graft was placed.
•Knee Immobilizer was applied to allow soft
tissue healing

10. Case 2
•20y/Male, Dang
•A/h/o RTA
•Presented to our center on the day of trauma
•C/o : Pain, Swelling and Deformity of Rt Hip
30. Intra-articular Fractures: Problems
•Immobilization results in joint stiffness
•Immobilization after surgery results in more stiffness
•Loss of articular congruency leads to shift in loading patterns – progression to
osteoarthritis
•Depressed articular fragments will not be reduced by closed manipulation
•Metaphyseal defects beneath reduced articular segments need to be filled
with bone grafts or substitutes to prevent articular fragment redisplacement/
settling
31. Articular Fractures: Treatment
•Anatomic Reduction
• No step-up and gaps, no depressions
•Maintenance of articular congruency
• So that load is evenly distributed
•Stable Internal Fixation (Absolute Stability)
• So that early mobilization is possible
•Early Mobilization
• Prevents joint stiffness and ensures healing
32. Concept of Absolute Stability
Definition: No micromotion between the fracture fragments
under normal physiological loading
◦ Open Reduction is required
◦ Anatomic Reduction is required
•Healing by Primary Intention
•No Callus Formation
33. Concept of Absolute Stability
•Methods :
• Lag Screw Fixation
• Axial Compression with Compression
Plating
• Tension Band Wiring
• Buttress plating
34. Articular Fracture : Principles
•Understanding the mechanism of Injury
•Evaluation of soft tissues
•Adequate imaging
•Timing of surgery
•Appropriate surgical approach
•Articular Reduction
•Buttressing of the metaphysis
•Post Operative Care
35. Postoperative Treatment
•Splinting for short duration to allow healing of soft tissues
•Active assisted exercises as soon as possible
•Regular X ray surveillance at follow-up
36. What’s New ?
•Concept of Absolutive Fixation
•Properties between Absolute and relative stability
37. Take Home Message
•Articular cartilage has a poor healing capacity.
•It is avascular and derives its nutrition from synovial fluid
•Proper flow of synovial fluid requires-
• Motion
• Load
•Early mobilization improves healing of articular cartilage
38. Take Home Message
•Anatomic Reduction-Often direct
•Stability –Absolute – Stable Fixation
•Early mobilization
•Anatomic Reduction + Stable Fixation + Early Mobilization Healing with Hyaline
