Computerised Navigation System (Nav-3)  for a Joint Replacement Surgery: A Boon for Patients

Share Now :

Computerized Navigation System in Joint Replacement has revolutionized Joint Replacement Surgery. Poor alignment is the most common cause of premature failure of the implant in manual Joint Replacement. New technology of computer based navigation system has completely eliminated poor alignment and made Joint Replacement surgery 100% accurate. The Computerized Navigation System (Nav-3) enables surgeons to consistently obtain results that are far more accurate than conventional methods. Dr. Ankur Goel is working on the most Advanced Navigation System for Joint Replacement by Computerized Navigation System (Nav-3) at Sri Sai Hospital Moradabad.

Since the level of accuracy is very high, it also helps in increasing the life of the implant by 20-25 years, and also reduces the blood loss to the patient. Patients who undergo this type of Surgery in our hospital are able to walk and climb stairs without assistance within a few days after surgery. The Computerized Navigation System helps the surgeon to make precise cuts and correct deformities in the knee. It also removes human errors in surgery.

Sri Sai Hospital, Moradabad uses Computerized Navigation System (Nav-3) to provide real-time, patient-specific information about patients during surgery, including infrared cameras, state-of-the-art software, due to while costly Investigations like Intensive CT and MRI Scans prior to surgery etc. does not need to be done. At the beginning of the operation, the surgeon strategically places small transmitters on the patient's leg. The surgeon then guides the foot through a series of prescribed movements, which, in turn, are recorded by the navigation's infrared camera and transmitted to a computer. The computer analyzes those positions to create an anatomical 'model' of the knee and updates this information throughout the procedure, displaying all relevant axes, angles and distances for the surgeon. Analyzing and providing this continuous data, navigation helps guide the surgeon through the bone cut, implant positioning.

What is Prematurity Birth of babies

What is Prematurity Birth of babies

What is Prematurity

  • Every year, an estimated 15 million babies are born preterm (before 37 completed weeks of gestation), and this number is rising.
  • Preterm birth complications are the leading cause of death among children under 5 years of age, responsible for approximately 1 million deaths in 2015 (1).
  • Three-quarters of these deaths could be prevented with current, cost-effective interventions.
  • Across 184 countries, the rate of preterm birth ranges from 5% to 18% of babies born.


Preterm is defined as babies born alive before 37 weeks of pregnancy are completed. There are sub-categories of preterm birth, based on gestational age:

  • extremely preterm (less than 28 weeks)
  • very preterm (28 to 32 weeks)
  • moderate to late preterm (32 to 37 weeks).

Induction or cesarean birth should not be planned before 39 completed weeks unless medically indicated.


Who is at risk for prematurity?

Many women have no known risk factors for premature birth. But several things can make premature birth more likely.

Women with these risk factors are more likely to deliver early:

  • Having had a past preterm labor or birth.
  • Getting pregnant within a short time (less than a year) after having had a baby.
  • Being pregnant with more than one baby.
  •  Having an abnormal cervix or uterus " Being younger than 16 or older than 35
  • Having health problems such as high blood pressure, diabetes, heart disease, or kidney disease or high levels of social and psychological stress.
  •  Smoking

 In addition, women who develop any of the following problems during pregnancy are more likely to deliver early-

  • Infections
  • High blood pressure
  • Diabetes
  • Blood-clotting problems
  • Problems with the placenta
  • Vaginal bleeding


How is prematurity treated?

Treatment will depend on your child's symptoms, age, and general health. It will also depend on how severe the condition is.

Treatment may include:

  • Corticosteroid medicine is given to the mother before a premature birth to help the baby's lungs and other organs grow and mature.
  • Watching the baby's temperature, blood pressure, heart and breathing rates, and oxygen levels.
  • Temperature-controlled bed or incubator.
  • Oxygen is given by mask or with a breathing machine called a ventilator.
  • IV (intravenous) fluids, feedings, or medicines.
  • Special feedings with a tube in the stomach if a baby can't suck.
  • X-rays or other imaging tests.
  • Skin-to-skin contact with the parents (kangaroo care).


What are the possible complications of prematurity?

Premature babies are cared for by a Neonatologist. This is a doctor with special training to care for newborns. Other specialists may also care for babies, depending on their health problems.

Premature babies are born before their bodies and organ systems have fully matured. These babies are smaller than they would have been if they were born at full term. They may need help breathing, eating, fighting infection, and staying warm. Extremely premature babies, those born before 28 weeks, are at the greatest risk for problems. Their organs and body systems are not ready for life on their own outside the mother's uterus. And they may be too immature to function well even with intensive care support.

Some of the problems premature babies may have include:

  • Keeping their body temperature steady or staying warm.
  • Breathing problems, including serious short- and long-term problems.
  • Blood pressure problems due to immaturity of various organ systems (especially low blood pressure in early hours and days).
  • Blood problems These include Jow red blood.
  • Blood problems. These include low red blood cell counts (anemia), yellow color to the skin from breaking down red blood cells (jaundice).
  • Kidney problems due to immaturity.
  • Digestive problems, including immature absorption and digestion. Most premature babies need intravenous IV nutrition for some time at birth. In some cases, there may be inflammation and death of parts of the intestine (necrotizing enterocolitis). Babies are often not able to feed by mouth until closer to their due date and will need tube feedings. The best feeding is mom's own milk. If this isn't possible, donor human milk from a milk bank is the safest alternative.
  •  Nervous system problems, including bleeding in the brain or seizures.
  • Infections.

Premature babies can have long-term health problems as well. Generally, the more premature the baby, the more serious and long-lasting the health problems may be.

Can prematurity be prevented?

More babies are surviving even though they are born early and are very small. But it is best to prevent preterm labor if possible.

It's important to get good prenatal care while you are pregnant. Your healthcare provider can help find problems and suggest lifestyle changes to lower the risk for preterm labor and birth. Some ways to help prevent prematurity include:

  • Stop smoking if you smoke. You should stop smoking before you are pregnant.
  • Finding out if you are at risk for preterm labor.
  • Learning the symptoms of preterm labor.
  • Getting treated for preterm labor

Your healthcare provider may give you the hormone progesterone if you are at high risk for preterm birth. Progesterone can help if you have had a past preterm birth.

Dengue Fever: Causes, Complications, and Vaccine Strategies

Dengue Fever: Causes, Complications, and Vaccine Strategies

Dengue is the most extensively spread mosquito-borne disease; endemic in more than 100 countries.  Approximately 2.5 billion people live in dengue-risk regions with about 100 million new cases each year worldwide. The cumulative dengue diseases burden has attained an unprecedented proportion in recent times with sharp increase in the size of human population at risk.Amid the rising cases, Uttar Pradesh has become one of the worst-hit states in India by the dengue fever outbreak.

Dengue is a mosquito-borne viral infection, and the virus responsible for causing dengue, is called dengue virus (DENV). There are four DENV serotypes, meaning that it is possible to be infected four times.While many DENV infections produce only mild illness, DENV can cause an acute flu-like illness, occasionally developing into a potentially lethal complication, called severe dengue. There is no specific treatment for dengue/severe dengue, however Dengue deaths are preventable if we take timely interventions.Early detection of disease progression associated with severe dengue, and access to proper medical care lowers fatality rates of severe dengue to below 1%. Until now, no vaccine has been developed to prevent Dengue virus. The only prevention is to avoid mosquito bites. Dengue prevention and control depends on effective vector control measures.

Dengue is one of the major public health problems which can be controlled with active participation of the community. Need is to organize health education programmes about dengue disease to increase community knowledge and sensitize the community to participate in integrated vector control programmes.

Urinary problems can be an indicator of Kidney Damage

Urinary problems can be an indicator of Kidney Damage

Urinary problems are commonly encountered in children of all age groups. It may vary from burning Micturating, pain during passage of urine, dribbling of urine, not passing urine in stream, recurrent urinary tract infection, bedwetting in older children, frequent passage of urine unknowingly in clothes. It is troublesome for the child most of the time. Sometimes it may become a social stigma, as no one likes to play with a child having wet and smelly clothes. It becomes difficult for the child to attend school, as frequent complaints from teachers and fellow classmates reduce the self-esteem of the child. These problems could be an indication of various Paediatric Urology diseases that may cause kidney damage if not detected and treated on time. Nowadays antenatal ultrasound done during pregnancy detect several common Pediatric Urology problems which can be treated after birth and hence kidney damage and an array of urinary problems can be avoided. Broadly there are four kinds of paediatric urology diseases encountered in day to day practice. Posterior urethra valve is a disease which can be detected during pregnancy before the birth of the child. There is partial obstruction in the urethra (part through which urine passes to come out of the body). If undetected for a long period of time and finally if the diagnosis is delayed, the child may have permanent kidney damage. Ultrasound, Micturating cystourethrogram are two investigations that can confirm the diagnosis. Treatment is done by Pediatric Cystoscopy in which no cut is made over body and obstruction is removed and the child leads a happy life thereafter. child may suffer from recurrent urinary infection, dribbling of urine Hydronephrosis is swelling up of the kidney because of obstruction in outflow of urine from kidney. It is usually diagnosed during pregnancy and Paediatric Surgeons operate and cure the disease by creating a pathway for drainage of urine as early as 4 to 6 weeks of age and hence kidney is protected from getting damaged. Vesicoureteric reflux (VUR) is a disease where the urine keeps circulating in the system. Urine is waste product of the body meant to be thrown out. There is unidirectional flow of urine from kidney to outside. Here, when we urge to urinate, bladder compresses and urine is sent back to kidneys, hence it keeps infecting and damaging the kidney. The child presents with recurrent urinary infections. The diagnosis is made by Micturating Cystourethrogram. Treatment is by creating a valve mechanism to prevent reflux and hence the cure. Neurogenic bladder is a complex entity due to neural dysfunction. So, the crux is don't ignore urinary problems in children. Meet your nearest Pediatric Surgeon whenever there is a problem so that the kidneys of your child can be saved in time before they get damaged.

Weight Loss and Bariatric Surgery Clinic

Weight Loss and Bariatric Surgery Clinic

Sri Sai Hospital is organizing  Weight loss and Bariatric Surgery Clinic for obese people on Every Tuesday. People who were obese and facing health problems due to obesity came to the Clinic for their medical check-up, which includes BMI, body fat analysis, blood sugar. Also free nutrition and diet advice was given by experts.

Dr. Zuhaib Naseem, Consultant Minimal Access and Bariatric Surgeon at Sri Sai Hospital said, "Today among all other diseases, obesity has emerged as one of the growing health problem among people especially those living in urban areas.  Sedentary life style and lack of physical exercise is one of the major cause of  obesity.  Also, an obese person can have other health complications like high blood pressure, heart disease, diabetes mellitus, sleep apnea etc. Hence it is essential for people with obesity to get the right medical treatment at the right time and protect themselves from further health hazards".

The camp was organized with the sole purpose of helping people to know their obesity level and opt for the right treatment. A person with a BMI (Body Mass Index) of 25 to 30 is said to be overweight and if it is greater than 30 it is generally considered obese. Overweight conditions can be easily managed with proper diet control, exercise and physical activities. In severe cases where BMI is greater than 30, it is often difficult to maintain and reduce weight. According to Dr Zuhaib Naseem of Sri Sai Hospital, bariatric surgery is an ideal option in such situations. Surgery reduces the size of the stomach and sometimes bypasses a part of the small intestine. Bariatric Surgery improves health problems related to obesity and also improves physical function, mood, and improved quality of life.

 Dr. Zuhaib Naseem said, "We will regularly conduct weight loss and bariatric surgery clinics every Tuesday at Sri Sai Hospital and it will be our pleasure to do more and more free camps in the near future".
