Spinal stenosis is a condition where a part of the spinal column becomes narrow. There are generally two types of spinal stenosis- lumbar stenosis and cervical stenosis. Lumbar stenosis is the form of the condition that affects the lower back. It is also the most common type of spinal stenosis.

Common Causes of Lumbar Spinal Stenosis
Some people may be born with a narrow spinal canal, but in most cases the condition is caused post birth. Here is a look at some of the most common causes for the spinal stenosis.

Overgrowth of bone- Osteoarthritis can sometimes cause bone spur formation, which in turn can lead to the stenosis at the lumbar region of the spine. This usually occurs in adults, as osteoarthritis is common after a certain age.
Herniated discs- A soft cartilage exists between the vertebrae, which cushions any impact on them. However, this cartilage dries up over time, and with age may lead to formation of crack on the exterior, which in turn causes suppression of the inner soft material and nerves of the spine.
Stiffened ligaments- The ligaments in the spine may become thick and stiffened over time and age. Due to the thickness of the ligaments, a bulge may occur in the spinal column and lead to lumbar spinal stenosis.
Injuries to the spine- Lumbar spinal stenosis may often be brought on by an injury to the spine. A spinal fracture resulting from an accident may narrow down the spine, which can cause the issue.
Tumours- A tumour may affect anyone at any point of time. These tumours may occur between the spinal cord and the vertebrae or between two bones in the vertebrae.
Symptoms of Lumbar Spinal Stenosis
Often the spinal stenosis may lie dormant and not produce any noticeable symptoms. However, it can still be diagnosed using an MRI or CT scan. However, all forms of the condition gradually progress and produce severe symptoms. This is why the treatment should be started as soon as the lumbar spinal stenosis is diagnosed, for the best result.

Here are common symptoms associated with the disorder

Numbness and tingling in the leg and foot.
Pain in the back
Leg cramps after long spells of standing or walking.
Weakness in the legs and feet.
If you observe any of the symptoms mentioned above, make sure that you visit an orthopaedist, so that the condition can be diagnosed and treatment can be initiated at soon as possible.

Lumbar Canal Stenosis - What Causes It?

Bone Fractures: Causes and Symptoms

'Fracture' is a medical term for a broken bone. According to an estimate, an average person has two fractures within their lifetime. When a force exerted is stronger than the bone itself, it can lead to a fracture. The risk and chance of fracture depend on your age. With age, bones tend to become brittle and, hence, a fall that would have been potentially harmless years ago can lead to a broken bone at a later age.

There are many types of bone fractures, but the main types are:

Closed fracture: A fracture in which the bone breaks but does not tear through the skin

Open fracture: Where the broken bone punctures through the skin and protrudes out. There's a greater chance of bone infection in an open fracture

Displaced fracture: In this type of fracture the bone snaps into more than two parts

Nondisplaced fracture: The bone cracks partly or wholly but it does continue to move

Some of the common signs and symptoms of a fracture are:

- Bruising and swelling of the bones
- Open fractures marked by protruding bones from the skin
- Loss of locomotive and functional ability of the injured area
- Deformity of the injured area
- Pain in the event of movement of the injured area

A fracture can be caused by a number of reasons, and they are:

- Injuries and accidents
- Falls and slips
- Wear and tear through overuse
- Sport injuries
- Fist fights and brawls
- Osteoporosis (a disease which causes bones to weaken in adults)
- Osteomalacia ( a disease caused due to softening of your bones, which is caused by a vitamin D deficiency.) Soft bones are more likely to bow and fracture than are harder, healthy bones.

Note:

Osteomalacia is not the same as osteoporosis. Osteomalacia occurs due to a defect in the bone-building process while osteoporosis develops due to a weakening of existing bones.



Bone Fractures: Causes and Symptoms

Mobility for a person is very important, and when you look through, the hip is a very important component to this. It connects the upper and lower parts of the body and helps in movement. It is a ball and socket joint, where the hip bone provides a socket, into which the upper part of the thighbone (femur) sits into, allowing for free movement.

Like any other human organ, the hip also is prone to damage. Be it natural ageing, infection, injury, or diseases, hip movement can be affected, leading to limited movement and increased pain and stiffness. For these people, being able to get back a hip which will allow them to be back on their feet is a boon for sure. It helps in relieving pain and improving mobility, almost giving people a second lease of life.

Reasons for hip replacement:

With natural ageing, the hip joint can lose its ability to move, due to normal wear and tear of the hip and thigh bones
Diseases of the hips (infectious or autoimmune) can also lead to hip replacement
Injury or trauma is another major cause that requires hip replacement
Joint problems, leading to repeated dislocations
Tumours of the relevant bones
Understanding the procedure in detail

The affected bones (whether diseases or worn out) are replaced with a prosthesis which is compatible with the normal body tissue.
While some materials fuse to the natural bone, others do not and are simply placed as a separate unit
This is a surgery which requires hospitalisation and stays for up to 5 days depending on patient s overall health condition
The entire procedure may take a couple of hours and is usually done under general anaesthesia
An incision is made through the side of the hip
Both the hip and the thigh joints are prepared, diseased tissue removed, re-shaped, etc. to make way for the prosthesis
The prosthesis is introduced through the same incision and positioned into place
As noted earlier, there are two types. The ones which fuse to the bone have pores in them into which normal bone eventually grows.
The other variety is the cemented version, and a glue is used to keep it in place
Most doctors now use a combination, that is cement a porous prosthesis, into which bone will grow, and the incisions are closed
The patient stays in the hospital for 1 to 4 days depending on overall health
Once discharged, infection and pain control are continued
Exercise and physiotherapy play a major role in restoring normal function
Weight management is also very important

Hip Replacement - Understanding The Procedure In Detail!

After a tough workout session or a strenuous day at the office, your muscles may feel floppy and exhausted until you have given them a chance to rest. However, persistent muscle weakness with no apparent cause or explanation can be a sign of an underlying medical problem.

What causes muscle weakness?
Voluntary muscle contractions and movement are generated when the brain sends a signal through your spinal cord and nerves to the particular muscle. If there are any hindrances in the connections between them, it can result in muscle weakness. However hard you try, the muscle is such cases becomes abnormal.

Here are some common causes of muscle weakness:

Lack of Use: One of the most common causes of muscle weakness, lack of muscle fitness may occur as a result of a sedentary lifestyle. If the muscles are not used, then the fibers are partially replaced with fat.
Ageing: As we age, our muscles tend to get weaker and lose strength. Muscles become bulky and recovery times during injury are greater. However, with physical activity, it is still possible to increase the muscle power. So stay active and instill strength in your muscles.
Infections: Infections and inflammation can cause temporary muscle fatigue. Even though recovery is quick, if the infection is severe the weakness can last for some time. Without proper care, it can lead to permanent damage.
Pregnancy: During and just after pregnancy, high levels of steroid in the blood and low levels of iron can cause muscle tiredness. Lower back pain is common during pregnancy and all your muscles may feel floppy.
Chronic Diseases: With conditions of diabetes, heart disease, kidney disease and anemia, it can lead to muscle weakness by thwarting the essential blood or nutrient supply to the muscles. Also, chronic pain related ailments cause weakness.
Injuries: Injury or trauma such as sporting injuries, pulls and sprains can deter the muscles. Along with localized pain, it can also lead to muscle weakness if not taken care of properly.
Sleep Disorders: With disturbed or reduced sleep there is a general sense of tiredness that leads to fatigue in the muscles. Insomnia, anxiety, depression and other mental disorders also affect the muscles a great deal.
Conditions affecting Nerves: Conditions like Myasthenia gravis or motor neuron disease affects the nerves and thereby fail to relay signals to the muscles, leading to weakness.
Genetic disorder affecting muscles: There are also certain inherited diseases which can affect the muscles like muscular dystrophy.
Spine-related disorders: Conditions like slip disc and other disorders affect the muscles served by the irritated or compressed nerves of the spinal cord.

Muscle Weakness - 10 Common Reasons Behind It!

A broken bone or a crack in the commonly known as a fracture. Any bone in the arm can be broken, but common areas for fractures in the arm is wrist, specifically the distal radius, forearm bones (radius and ulna), elbow, humerus and shoulder. 

What causes fracture in bones?

Fall: Falling an outstretched hand or elbow is the most common cause of a broken arm.
Sports injuries: Direct blows and injuries on the field or court are a common cause of all types of arm fractures.
Significant trauma: Any of your arm bones can break during a car accident, bike accident or other direct trauma.
Abuse: In children, a broken arm may be the result of child abuse.
How to identify?

An audible snap or cracking sound may be your first indication you've broken an arm.

Signs and symptoms include:

Severe pain, which may increase with movement
Swelling
Bruising
Deformity, such as a bent arm or wrist
Inability to turn your arm from palm up to palm down or vice versa
When to see a doctor?

If you have enough pain in your arm that you can't use it normally, see a doctor right away and do the same for your child. Delay in diagnosis and treatment of a broken arm, especially for children who heal faster than adults do, can lead to poor healing and deformity.

Fracture In Upper Limb Bones - 4 Things That Can Cause It

Spine surgery is conventionally performed as  open surgery , which means the region being worked on is opened with a long entry point to permit the surgeon to view and access the area. Technical and scientific advances have permitted more back and neck conditions to be treated with a less obtrusive surgical technique. The minimal invasive spine surgery (MISS) does not include a long cut, and it prevents causing damage to the muscles around the spine. As a rule, this causes less pain after the surgery and a speedier and healthy recovery.

Spine surgery is normally suggested when non-surgical treatments like medicinal or exercise based methods have not helped in lessening the excruciating symptoms of your back problem. Moreover, surgery is just considered if your doctor can pinpoint the correct reason of your pain, for example, a herniated circle or spinal stenosis. 

MISS is also called less obtrusive spine surgery. In these procedures, surgeons utilise particular instruments to get to the spine through little cuts. The surgery process is as follows:

During the surgery, a little entry point is made and the tubular retractor is embedded through the skin.
It is also inserted into the delicate tissues down to the spinal cord.
This makes a passage to the little range where the problem exists in the spine.
The tubular retractor holds the muscles open and is set up all through the surgery.
The surgeon gets to the spine utilising the little instruments that fit through the focal point of the tubular retractor.
Any bone or disk material that is expelled goes out from the retractor.
Any gadgets needed for the fusion process, for example, screws or rods, are embedded through the retractor.
A few surgeries require more than one retractor.
Keeping in mind the end goal to see where to put the entry point and embed the retractor, the surgeon is guided by fluoroscopy.
This strategy shows ongoing X-ray pictures of the patient's spine on a screen throughout the surgery.
The surgeon additionally utilises a microscope to enlarge the view through the retractor.
Towards the end of the procedure, the tubular retractor is expelled and the muscles come back to their original position.
This restrains the muscle damage that is more ordinarily found in open surgeries.
It is very important to talk about these risks with your doctor before your surgery or procedure.

Infection: Antibiotics are consistently given to the patient some time before, during, and regularly after the surgery to reduce the danger of infections.
Bleeding: A specific measure of bleeding is normal; however, this is not commonly dangerous.
Pain in the grafted area: Some patients will encounter surgical pain at the bone joint site.
Recurring symptoms: A few patients may encounter a repeat of their side effects.
Pseudarthrosis: Patients who tend to smoke are more prone to pseudarthrosis. This is a condition wherein there is insufficient bone formation. In case that this happens, a minor surgery may be required.
Nerve damage: It is possible that the nerves or veins might be harmed during these operations. These complications are extremely uncommon.
Blood clots: Another complication is blood clots in the legs. This poses a threat because these clots can break off and settle in the lungs.
