Dynamic signage is rocking the advertising world, this revolution is being monopolized with advertising digital posters, allowing almost any business to deploy a digital advertising solution, and it could be in the form of an info-mercial rather than a advertisement.

Why is this marketing solution so effective?

A business owner can produce some fantastic media by using free content creation tools that are free on line, then when they are happy they can transfer the multi media content to the memory device as these support formats such as JPG (digital image), MPEG1, MPEG2, MPEG4 (digital video) and MP3 audio files. You do not need to have any programming knowledge or experience, if you have ever uploaded a video to you-tube can do this, it is so simple even a 10 year old can do it. Businesses such as Walmart, Tescos, Home Depot and Disney are even using this basic form of marketing however it has two huge benefits over previous, printed forms of marketing.

The first advantage is that if you find you have an overstock of an item you can change your promotion to sell this gadget maximizing your profit for around 15 minutes work, this time can be reduced dramatically if your suppliers give you marketing videos of the products you are reselling, just drag and drop the content from the DVD to the memory card or USB flash drive.

The second benefit is that these can be placed anywhere in a store, from a window facing the outside to behind the receptionist in a companies reception area. If you can hang a picture frame you can hang an advertising digital poster. Just remember you need a power source as the posters come with a power lead that is 2 meters long.

Ideal for exhibitions or temporary locations, as there is no real cabling needed for them to operate, just a mains socket.

Birmingham Hip Resurfacing

Hip resurfacing is ideal for many younger, active patients who suffer from hip pain. Many people stay physically active far into their late fifties and beyond so there’s an increased need for an alternative to total hip replacement that accommodates their age and lifestyle.

What Is the BIRMINGHAM HIP* Resurfacing Device?

Your hip is a socket and ball joint where the thighbone and pelvis come together. As your leg moves, the ball of your thighbone (called the femoral head) moves and rotates against the socket portion of your pelvic bone (called the acetabulum). If your hip joint is diseased due to certain kinds of arthritis, or previous damage, it will become less functional and more painful over time. When your hip pain increases to the point that it can not be helped by usual measures such as pain medicine and exercises (physical therapy) and your ability to move your hip decreases, affecting your ability to do your daily activities, it may become necessary to surgically replace the hip joint.
The BIRMINGHAM HIP™ Resurfacing (BHR™) device has two parts: a socket in the shape of a shallow cup (acetabular component), and a cap in the form of a ball head (femoral resurfacing component). See Figure 1.
The cup replaces the damaged surface of your hip socket (acetabulum). The cap covers the ball-shaped bone at the top of your thigh (femoral head), and the cap has a small stem that is inserted into the top of your thighbone. The cap moves within the cup. The surfaces that rub against each other (the bearing couple) are made from highly-polished metal. This type of bearing couple is called a metal-on-metal bearing couple.

Hip resurfacing versus a total hip replacement:

With a hip resurfacing device, the surgeon covers your hip socket with a metal cup, and covers your femoral head with a metal cap. (See Figure 1) The BHR System is a hip resurfacing device. With a total hip replacement device, the surgeon covers your hip socket with a cup and replaces your femoral head with a metal ball attached to a long metal stem. The metal stem is inserted into your thighbone. (See Figure 2)

BIRMINGHAM HIP* Resurfacing System Surgery

BIRMINGHAM HIP Resurfacing System surgery has helped more hip pain patients around the world than any other hip resurfacing surgery available. Their experience – and yours – can be broken down into three basic parts.

* Before Surgery – Getting Ready
* Day of Surgery – What to expect
* After Surgery – Smart Recovery Strategies

BEFORE SURGERY – GETTING READY

BIRMINGHAM HIP* Resurfacing System procedure starts with an appointment with your orthopaedic surgeon.
This initial surgical consultation may include X-rays, a medical history and physical, and a list of your medications and allergies. Your surgeon may review the BIRMINGHAM HIP Resurfacing System procedure and answer any questions you have about hip pain, hip resurfacing or any other pre-surgical issues.

Your doctor may want you to meet with a Physical Therapist (PT) even before the surgery. The PT may give you some tips on preparing your house for rehabilitation, and on how you should sleep, get out of bed, sit, get up, and walk following surgery. Some things you can do before surgery to prepare for the rehabilitation period are:

• Add extra cushions to couches and chairs. The extra height will make it easier for you to lower and raise yourself from the chair.
• Have armchairs available. During rehabilitation, you may be told only to sit in armchairs, as you will need the arms to help you sit down and get up.
• Arrange to have an elevated toilet seat and/or support bars fitted in your bathroom.
• Move items you may need to reach to shelves or tables above waist level.
• Remove all throw rugs and anything else on the floor that might cause you to slip or trip and fall.

DAY OFSURGERY – WHAT TO EXPECT

After being admitted you will be taken to the appropriate pre-surgical area where the nursing staff will take your vital signs, start intravenous (IV) fluids, and administer medications as needed. You will be asked to empty your bladder just prior to surgery, and to remove all jewelry, contacts, etc. Once you change into a surgical gown you will be taken to the operating room. The anesthesiologist will meet you and review the medications and procedures to be used during surgery.
Your surgeon will start the operation with a technique to approach the hip joint. There are several different surgical approaches available, and your surgeon will choose the approach which best suits his or her experience. There are subtle differences in each approach which will result in slight variations in the post-operative regimes used in the recovery and rehabilitation from the surgery.

The surgeon then prepares the bone for resurfacing, using specialized instruments supplied by Smith & Nephew , the manufacturer of BIRMINGHAM HIP* Resurfacing System implants. The head of the femur is prepared to receive the resurfacing component, and the socket is shaped to accept the new resurfacing cup. Once this is accomplished the socket is inserted in a position to give stability to the hip, and allow the bone to grow around it. This encourages long-term security in the newly refinished hip joint. Finally, the resurfacing head component is fixed into position using bone cement.
Following a careful inspection of all components your surgeon will then close the surgical approach path with sutures. It is common for the surgeon to leave a drainage tube exiting from just below the incision for a couple of days after BIRMINGHAM HIP Resurfacing System surgery, but in some cases it is not necessary.

AFTER SURGERY – SMART RECOVERY STRATEGIES

Most patients are in the hospital from 4 to 6 days. The surgery usually takes 2 to 4 hours to perform. You will use walking support (canes, crutches) for about six weeks after surgery while your hip muscles are healing. You may be told not to bend your hip or waist to more than a 90-degree angle during the healing time (rehabilitation).
Before you go home, your Physical Therapist (PT) will teach you to climb stairs and how to move from a bed, chair, and car. Your PT may also give you a list of exercises to do at home every day. These exercises will help you become as independent as possible in your personal care and daily activities after you return home. Physical therapy will also help prepare you for more difficult exercises, movement, and activity.

The weeks after hip surgery

Most of your therapy and healing (rehabilitation) will occur once you have checked out of the hospital. Your PT will design an exercise program to increase motion and strength of your hip, and will teach you the exercises, making sure you know proper way to do the
exercises before you begin. The success of your rehabilitation is very dependent on how dedicated you are to the physical therapy program.

Walking is the key to a speedy return to your active lifestyle. But don’t overdo it. Swimming is good, but you shouldn’t attempt other sporting activities, including golf, until getting cleared by your surgeon. Talk to your doctor about planning a regular exercise and stretching program.

Precautions after BIRMINGHAM HIP Resurfacing System surgery
The first six to 12 months after a BIRMINGHAM HIP Resurfacing System operation are the most vulnerable for the new hip joint. You’ll want to try out your new resurfaced hip. But you’ll also want to be smart, and take it slowly.
Avoid heavy lifting and high-impact activities like jogging or jumping. Don’t twist or squat. Driving can resume around four to five weeks after hip resurfacing surgery, pending physician approval, as can sexual relations – but try to avoid extreme movements of the hip for around three months.

Some pain is normal and expected during your rehabilitation period, and the pain should slowly decrease in the weeks following surgery. If you experience any serious, mmediate, constant hip pain or pressure or feeling of unsteadiness, or if you are suddenly unable to put weight on your hip after the early post-operative pain has gone away, you should contact your doctor. These signs (symptoms) may be a signal of a serious problem (such as bone breakage, dislocation, infection, device loosening, movement, or breakage). Any of these problems may require medical attention including additional surgery. Remember to listen to what your body tells you, and what your doctor recommends. If you begin to have pain or swelling, contact your physician for advice.

Follow your doctor’s schedule for examinations after surgery. Routine examinations will include regular X-ray exams to look for any problems such as hip bone or device breakage, position changes, or anything abnormal. X-rays will also check the progress of bone healing around the implant.

Your new hip device may activate metal detector alarms. Tell the security attendant about your artificial hip when passing through security checkpoints in airports, stores, and public buildings.

Specific potential benefits of the BIRMINGHAM HIP* Resurfacing System include:

• The BHR’s metal cup will not chip or crack as ceramic components can.
• The BHR does not cause thighbone (femoral shaft) fractures as total hip replacement systems can.
• The BHR may make future revision surgery easier because hip resurfacing surgery leaves your femoral head in place and there is no large metal stem placed in the thighbone.
• Revision surgery of a total hip replacement where your femoral head has already been removed and a large stem is already in place can be a more difficult operation.
• Dislocation of the ball head from the socket is less common with the BHR device than with total hip replacement devices. In the clinical study, 0.3% of BHR patients experienced dislocation, compared with between 1% and 4.2% of total hip replacement patients from comparison studies.

Some of the Potential Risks of the BIRMINGHAM HIP* Resurfacing System

The potential risks of any hip joint replacement include:

• Damage to blood vessels, or temporary or permanent nerve damage during surgery,
• Sudden drop in blood pressure during surgery due to the use of
  bone cement
• Blood circulation problems because of surgery or during recovery including blood clots in the legs or lungs or heart attack.
• Allergic reactions to the device material or to medications you are given,
• Surgical wounds that take a long time to heal due to many reasons such as poor skin condition, infection, poor blood circulation, bad hygiene, etc
• Infection related to surgery and wound healing. Infections may occur months to years after surgery and these infections are difficult to treat and may require reoperation with removal surgery and later replacement at another time.
• Dislocation of the hip, device loosening/shifting, or device wear/breakage due to muscle and fibrous tissue lack of firmness (laxity). Device placement in the wrong position in the bone, poor attachment of the device to the bone, too much weight or activity put on the device, or accidents affecting the hip joint like falls (trauma),
• Damage to the bones and tissue (tissue necrosis) near the hip joint, including loss of the surrounding bone (osteolysis) or staining of the hip joint fluid (metallosis) due to wearing away of the metal parts over time.
• Change in the length of the leg in which the device is placed,
• Device breakage due to weakening of the metal over time (fatigue fracture),
• Bone breakage due to osteoporosis or accidents (trauma),
• Bone loss or too much bone formation near the implants in response to the surgery or to the presence of the device in the bone.
  These potential adverse effects may require medical attention or additional surgery. Rarely do complications lead to death.

The potential risks of the BHR device as compared with a total hip replacement system include:

• The risk of femoral neck scratching (notching) during surgery that can lead to femoral neck fracture after surgery. This occurred in less than 1% of BHR patients in the clinical study.
• The risk of femoral head collapse. This occurred in less than 1% of BHR patients in the clinical study.
• The risk of femoral head collapse. This occurred in less than 1% of BHR patients in the clinical study.
• The risk of avascular necrosis. This occurred in 1% of the BHR patients in the clinical study.
• If the ball cap part of BHR device must be removed (revised), your surgeon will likely put a total hip replacement metal stem in your thighbone (see Figure 2).

These complications may require surgery to change from the BHR device to a total hip replacement device. You should compare these risks to the potential benefits of a BHR system, as described above.

What Do the Clinical Studies Show?
A clinical study was performed to evaluate the safety and effectiveness of the BHR device. Complication (safety) information was collected from the entire group of 2,385 study hips. Effectiveness information was collected from the first 1,626 of the 2,385 hips because these 1,626 hips have the longest follow-up. There is 5 year follow-up information for 546 of these 1,626 hips.

Safety Data
The overall complication rate and the types of complications in the BHR study group were generally similar to the complications reported for other hip replacement systems. Complications led to revision surgery in 27 out of 2,385 hips. The 1.13% revision rate at 5-years after surgery from all complications was comparable to the revision rates reported for total hip replacement devices. There were no deaths related directly to use of the device in the study. All deaths were from other medical problems.

recovery time on wisdom teeth removal + help with some "tooth" terms?

So I know it has been asked a lot on here, but I keep seeing things I do not understand like: "dry socket"? and "impacted"

So all I know is that my wisdom teeth, the two bottom ones are growing in sideways and I'm having them taken out tomorrow.

Now, my question is about the recovery time:
So I am missing class tomorrow so I can go get these out, and I cannot possibly miss class again on Monday so do you think that I will be in condition to drive about 40 miles sunday night if my surgery is on Friday morning?
Also, is the pain so bad that I will not be able to walk up and down the UCLA hills to class and to pay attention in class?

How is talking like ? I am a French major and I'm sure i will need to fully converse in French on Monday.

By the way I am 19 , going onto 20- I hear it is easier to heal when one is younger?

I've had all 4 wisdom teeth removed (impacted) between the ages of 20 and 25.

Impaction is your teeth have not surfaced. They are under the gum and most often are growing in sideways. The fear that dentists have is:
the tooth can press on a nerver, crowd other teeth out or become a source of infection.

Removing these teeth is a preventative measure. Dry socket is a complication that involves the bony area where the tooth was removed, it does not form a solid clot and can become very painful. The dentist has to "pack" this area with gauze.

This does not occur with every type of extraction.

The first day you will definitely be in pain and may have to take a strong pain killer to get you through the night or even have to take it for a couple of days. Then the pain will start to decrease and you can take Tylenol or Motrin. You can use cold compresses to help bring the swelling down.

Gargle with warm salt water. Be careful of the foods that you eat. The first few days---applesause, yogurt, jello, etc..

Its just better to stay away from spicey foods or those that may irritate your gum to chew.

By Monday you should be fine. You may be sore, but the pain will be tolerable.

Good luck to you.
