Hip Implants: Know Them Before You Get Them

Hip implant surgery is important if a part or the whole hip becomes damaged after an injury or a disease or wear downs after a disease related to joint. To have the person return to normal life and get some relief from the excruciating pain, replacing the affected part becomes of pivotal importance. The hip joint is replaced with an artificial joint or implant.

Types Of Hip Implants

Depending on the severity of the condition, the doctors can opt for either one of the following types of hip implants:

  • Complete hip implant where the joint is removed and a ball is inserted. The socket is then attached by roughing a part of the bone to create the necessary space. The ball and the socket are then cemented using various techniques and materials. In some cases, the cement is not used and the bone is roughened in a special way instead that would allow it to grow on the parts of the implants.
  • Partial hip implant where only a certain part of the joint is removed.
  • Hip resurfacing is used for younger patients or to improve mobility which is affected by arthritis. It replaces the socket and resurfaces the head of the femur instead of removing it.

The Design Of The Hip Implant

There are different types of materials being used for hip implants to make them more efficient. The design, however, pretty much remains to be the same. The design of the hip implant makes use of:

  • A metal stem which is inserted into the femur. It can also be used to keep the implants in place.
  • A ball which acts like the moveable joint and gives the hip its mobility
  • A socket which is attached to the pelvis which connects the ball to the stem
  • The bearing which gives the ball a smooth surface it can rotate on. It is the part where the ball and the socket rub together. The purpose is to give Hip its:
    – Mobility
    – Flexibility
    – Range-of-motion
    – Performance
    – Durability

Materials Used For Hip Implants

Combinations of different equipment are now being used to make the designs of the hip implants more efficient. The most common ones being:

  • A metal ball which is attached to a plastic socket. This metal and plastic approach is the most widely used
  • Plastic socket with a ball made of ceramic or in some cases ceramic ball used in combination with a ceramic socket. The latter is more common for patients who lead a fairly active life or a still young.
  • A metal ball with a metal socket. This one is used for young active patients

The hip implant makes use of a major surgery, and it is important to discuss all the possible alternatives with your doctor before coming to a conclusion. A lot of health, age and lifestyle factors will come into play when it comes to deciding the type of implant and the material which is used for the implant.

FAQs Related to Hip Implants

If you are thinking to have a hip replacement surgery, then it is important for you to know the basic of hip replacement surgery, such as the hip implants that your surgeon may be using.

hip-implants-prosthesis

Hip Implant Basics

Our hip joint comprises of two major parts, which include a femoral head (ball) at femur (the top of your thighbone) that fits into the acetabulum (a rounded socket) in your pelvis. The ball rotates within the acetabulum’s curved surface. During a hip replacement surgery, the acetabulum is replaced by an acetabular. Besides, the femoral stem is implanted into the ball (the femoral head) and the femur and is fitted in the acetabulum. This helps in connecting the leg to the hip and enables movement.

What Is A Hip Implant Made Of?

Even though there are varied models and designs of hips that are built by a number of manufacturers, but there are three major elements of an artificial hip, which includes a stem that is implanted into the thigh bone (the femur); a cup that attaches to the pelvis and a ball that is attached to the top of the femur.

The modern hip implants, famous since the 1970s, are created by combining different materials, such as metals, ceramics and plastics. The most common material used for making hip implants is cobalt chrome, titanium and stainless steel. Most of the recent hip implant devices are metal-on-metal designs, which have been created with the hope that hip surgery would last longer and provide pain-free flexibility for more years.

How Much Does It Weigh?

Your surgeon will select the implant that is most appropriate for you and fits your anatomy, and lifestyle. Generally, a complete hip system (liner, shell, head and stem) weighs between 1 to 2 pounds, which depends on the kind of material that is used.

Hip Surgery – Providing Relief to your Hip Pain

A surgery is usually the last option a doctor offers for your treatment and is often when it is imperative to do it, and when other methods of treatment seem ineffective. However, in today’s time with advanced medical facilities most surgeries are successful and hence the fear of surgery is gradually diminishing. Surgeries of all kinds are on a rise and hip surgery although not very common earlier is also being performed on a large scale.

Hip Prosthesis

Excessive unbearable pain in the hips, loss of mobility, loss of sleep, pain in the joints, seasonal pain during change of weather especially humid weather, degeneration of bones and sudden accidents are primarily the reasons for a hip bone treatment. Depending upon the condition of the patient, and after performing several x-rays and tests an orthopedic decides which method will suit the patient best in getting relief from the pain.  At times a minimal invasive surgery is enough to provide you relief from the pain instead of a total hip surgery. This prevents the patient from an elongated treatment and early recovery.

Different Methods of Hip Treatment

Arthroscopy

Bipolar Hip Prosthesis

In arthroscopy, the area of the hip discomfort is viewed through a camera and the problem is identified and treated. Through arthroscopy the damaged cartilage can be trimmed, the loose debris can be removed from the hips, and also irrigating the inside of the hip.

Osteotomy

In osteotomy, it is like a partial surgery where the bones are cut, reshaped or partially removed to shift the stress from the diseased tissue to a healthy tissue.

Internal fixation

In this method the broken bones are fastened with a small metal device to heal the fracture faster.

Total Hip Replacement

When the above methods do not seem to be effective enough to provide relief to the patient the doctor goes for total hip replacement.  This method involves replacing the painful damaged hip part with artificial hips called prosthesis. The prosthesis has three components: a socket, ball, and a stem. The outer shell is made of metal usually and the inner shell of either plastic or metal. The joining of the socket with the metal ball makes the movement of the hip smooth and frictionless.

The total hip fixation is also of two types:

Cemented Hip Implant

Femoral Neck Ball

In this kind of hip implant the bone cement is injected into the prepared femoral canal. Bone cement is a grout that helps position the implant within the bone. This grout helps the implant to be positioned in the required position.

Porous Hip Implant

In this type of hip implant, it is designed to engage the bone within the canal and allow the bone to grow into the porous surface. The femoral canal is prepared in such a way that the implant is fit tightly initially. In this method there are possibilities of the ingrowths of the bone to provide additional fixation to hold the implant as per the desired position.

Hip Implant surgeries are an effective way to reduce the pain and increase your mobility. Thousands of surgeries are being preformed successfully every year to provide relief to the ailing persons.

Orthopedic Surgical Instruments – A must for Surgeons

Surgeries are often the most dreaded and paradoxically also life saving procedures that help a person get back to a normal healthy living. In the case of orthopedic surgeries, it is primarily done to restore the function of the skeletal system. For performing these surgeries the surgeons need specially designed tools that have specific functions and are used for general use and for specific use. These tools basically provide assistance to the surgeons for the step by step systematic and proper handling of the surgery.

As technology progresses and medical innovations are carried out almost on a daily basis these tools have become more and more sophisticated and specific giving improved results.

Orthopedic surgeries can include a hip replacement surgery or hand surgery to release tendons for Carpal Tunnel Syndrome. The range of skills required in the process of an orthopedic surgery and the instruments needed to accomplish this task can be very wide. Surgeons require very specific instruments for various kinds of surgeries which can include power drills to delicate micro-surgical instruments in another.

The different types of orthopedic surgical instruments include:

Bone Instruments: Bones are one of the hardest parts of our body and fixing and cutting through them is not a very easy job. The instruments required for making these cuts are generally powered tools. Some are used by the hands like the straight hand saw which also includes the hack saw and the saber saw. In the more specialized surgeries like the knee surgery where more accurate and measurable cuts are required the “gigli” saw is used which is like a cable made of sharp strands of wire.

The asternal saw is a reciprocating bone cutter which has a powered rotary oscillation that provides smooth controllable cuts and is mostly used for cutting the ribs or the skull.

A Cosotome is a powerful rib cutter which has two levers, the first one grasping the rib and the second cutting through the ribs. It is used to pertain access to the thoracic activity.

In back surgery “rongeurs” are used to cut the small bone.

For most bone surgeries you require automatic drills to instill pins, screws and plates. Pliers, screw drivers and mallets are the hand tools used in most of the surgeries for skimming bone of the surface.

Tissue Instruments: For constructing the broken tissues a number of new instruments have entered the market. However, the basic instruments like the scissors, clamps, and retractors. Each one has its role. The scissors ofcourse is used for cutting, the clamps for stopping the blood vessels from bleeding and the retractors does the work of holding back the tissues so that the surgeons can operate freely.

Prosthesis: This is one of the most regular type of orthopedic surgery being done. Several types of instruments are required to perform this surgery. It includes chisels, glue, power tools, reamers, and calipers. All these instruments have different roles to help in replacing the bone with an artificial one.

Surgical instruments play a crucial role in the rate of success of the surgery. The material that gets used in making of these instruments helps in improving the sustainability and results of the surgery.

Hip Joint Replacement Surgery – An Analysis

Austin Moore Hip Prostheses

Like all other major surgeries, hip replacement surgery is suggested, when the patient is unable to take the pain in the hip area and therefore recommended to go for a surgery. The mental make-up of any patient during a surgery has to be strong along with the basic parameters of health doing well. A surgery is often recommended when it is seen to be the most effective option to decrease the pain and get the patient to lead a normal healthy life.

What is the Process Involved in a Hip Replacement Surgery?

The normal hip joint is a ball and socket joint and the hip replacement surgery involves replacing of the diseased ball and socket joint with an artificial metallic ball with the stem inserted into the femur bone with an artificial plastic cup socket. The metallic artificial ball and stem are referred to as the “prosthesis”.

This process requires a surgical procedure for the orthopedic surgeon to make the replacement from the original joint with a prosthetic one that delivers almost the same functions like the original. Once the artificial ball and the plastic cup socket are inserted in the hip joint area, it needs to be cemented in some cases.

In some cases joints are cemented for the attachment of the artificial joint to the bone which does the work of glue. There are also some joints which are not cemented. They instead use a porous coating that is designed to allow the bone to adhere to the artificial agent. As time passes by, new bone grows and gradually fills up the porous coatings, thereby attaching the joint to the bone.

How is Hip Replacement Surgeries Useful?

Hip replacement surgeries help in relieving the pain to the patient. Patients suffering from arthritis are usually prone and more likely susceptible to the pain in the hip joints and need the surgery when the pain becomes unbearable. Usually, people above the age of 60 or older are faced with this problem. In some cases, it may be for younger people as well, but the replaced artificial joints have a certain life span and may need to be replaced again after a stipulated period of time.

Hip pain surgery can help you resume to your normal activities which was being hindered due to the pain, like bathing, preparing meals, doing household chores, and walking.

If you have been using a cane or a walker for your walking, a hip replacement surgery can help you resume to a normal walking lifestyle.

A lot of people complain of sleeping disturbances due to the pain in the hip joint, a hip replacement surgery, can give you back, a peaceful sleep in the night.

Risk Involved in the Surgery and After Care

Risks Involved:

  • Anesthetic risks (common to all surgery)
  • Likelihood of infection which can be both of the wound and the artificial hip joint itself
  • Dislocation of the artificial hip joint which though is very unlikely but the risk is always there
  • During any kind of surgery the development of blood clots is a possibility
  • A change in the length of the leg that has been operated upon
  • Damage to the nerves and the blood vessels surrounding the hip joint

After Care or Recovery:

  • Till the soft tissues around the new hip joint are healed, special care needs to be taken for the movements around the hip joint area. One has to remember that it is not the natural hip so a hip prosthesis has a limited range of movement.
  • The first six weeks after surgery is a very high risk time for dislocation of the new hip.
  • The guidelines prescribed by the doctor on the physical movement of the operated patient should be duly followed.
  • Some of these guidelines include; do not cross the legs, do not bend down low, avoid lifting heavy objects, avoid forceful or jarring movement of the hip.
  • Avoid lying on the operated side, do not stand for long periods, sit on a firm chair with support to your arms, and treat scratches and cuts promptly to decrease chances of infection affecting the new joint.

Surgeries are a crucial time of a patient’s life and if dealt with patience and the right doctor accompanied by the right treatment with a positive frame of mind , it gives out a successful result.
